Caution Regarding Forward-Looking Statements
This report contains certain forward-looking statements within the meaning of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended. Forward-looking statements include statements regarding the goals, beliefs, plans or current expectations of First Trust Advisors L.P. (“First Trust” or the “Advisor”) and/or Horizon Investments, LLC (“Horizon” or the “Sub-Advisor”) and their respective representatives, taking into account the information currently available to them. Forward-looking statements include all statements that do not relate solely to current or historical fact. For example, forward-looking statements include the use of words such as “anticipate,” “estimate,” “intend,” “expect,” “believe,” “plan,” “may,” “should,” “would” or other words that convey uncertainty of future events or outcomes.
Forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of any series of First Trust Exchange-Traded Fund III (the “Trust”) described in this report (each such series is referred to as a “Fund” and collectively, the “Funds”) to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

We undertake no obligation to publicly revise or update these forward-looking statements to reflect events and circumstances that arise after the date hereof.
Performance and Risk Disclosure
There is no assurance that any Fund described in this report will achieve its investment objective. Each Fund is subject to market risk, which is the possibility that the market values of securities owned by the Fund will decline and that the value of the Fund’s shares may therefore be less than what you paid for them. Accordingly, you can lose money by investing in a Fund. See “Risk Considerations” in the Additional Information section of this report for a discussion of certain other risks of investing in the Funds.
Performance data quoted represents past performance, which is no guarantee of future results, and current performance may be lower or higher than the figures shown. For the most recent month-end performance figures, please visit www.ftportfolios.com or speak with your financial advisor. Investment returns, net asset value and share price will fluctuate and Fund shares, when sold, may be worth more or less than their original cost.
The Advisor may also periodically provide additional information on Fund performance on each Fund’s web page at www.ftportfolios.com.

Shareholder Letter
First Trust Exchange-Traded Fund III
Semi-Annual Letter from the Chairman and CEO
January 31, 2023
Dear Shareholders,
First Trust is pleased to provide you with the semi-annual report for the Managed Volatility Funds of First Trust Exchange-Traded Fund III (the “Funds”), which contains detailed information about the Funds for the six-month period ended January 31, 2023.
Given recent inflation data, the Federal Reserve’s (the “Fed”) monetary policy remains front and center in most discussions regarding the outlook of the U.S. economy. Annual revisions to the Consumer Price Index released on February 10, 2023, showed that prices climbed at a 3.3% annual rate in the last three months of 2022, not the 1.8% rate reported four weeks prior, according to Brian Wesbury, Chief Economist at First Trust. Additionally, “core” inflation, which excludes volatile food and energy prices, was also revised upwards from 3.1% to 4.3% over the period. Furthermore, January’s 2023 jobs data came in better than expected, with non-farm payroll employment rising by 517,000. It is precisely this situation: stubbornly high inflation, strong jobs growth and increasing interest rates, which has many pundits debating whether the typical U.S. consumer can remain healthy enough to help ward off an economic recession.
As many investors know, the consumer is an essential driver of economic growth in the U.S. On average, over the 15-year period ended October 1, 2022, consumer spending accounted for 67.8% of the U.S. gross domestic product (“GDP”). Crucially, recent data regarding consumer health has been mixed, in my opinion. On one hand, the Commerce Department reported that in December 2022, the U.S. savings rate rose to its highest level in seven months, coming in at 3.4%. On the other hand, while December’s savings rate was a welcome reversal from the declines suffered throughout 2021 and 2022, it could indicate that consumers are beginning to pull back on discretionary spending amidst a cloudier economic outlook, according to Bloomberg. Recent data shows that the average interest rate on U.S. credit cards rose to 19.07% in the fourth quarter of 2022, its highest level in over 50 years. Additionally, U.S. credit card debt reached a record $930.6 billion in the fourth quarter, jumping 18.5% year-over-year. Even so, debt service payments accounted for just 9.75% of disposable personal income in the third quarter of 2022. This figure is higher than its historic low of 8.33% set in 2021 but is also well below its peak of 13.17% set in 2007. In my view, it is worth keeping an eye on debt service payments. If higher payments lead to a decline in discretionary spending, it could negatively impact GDP.
I would like to take a moment to remind you that even though nearly three years have passed since the World Health Organization initially declared the coronavirus outbreak a global pandemic, the economic impact of worldwide lockdowns and the subsequent governmental stimulus is still very real. China, for example, only recently dropped its requirement that incoming travelers must quarantine before entering the country. In addition, the global economy has yet to fully absorb the impact of the fiscal policies enacted to jump start consumer spending in 2020, in my view. As evidence of this, each of the countries that comprise the G-10 currently has a headline inflation rate that stands well above its stated target. Central banks likely have more work to do, in my opinion.
Thank you for giving First Trust the opportunity to play a role in your financial future. We value our relationship with you and will report on the Funds again in six months.
Sincerely,
James A. Bowen
Chairman of the Board of Trustees
Chief Executive Officer of First Trust Advisors L.P.

Fund Performance Overview (Unaudited)
First Trust Horizon Managed Volatility Domestic ETF (HUSV)
The investment objective of First Trust Horizon Managed Volatility Domestic ETF (the “Fund”) is to provide capital appreciation. Under normal market conditions, the Fund seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in common stocks of domestic companies listed and traded on U.S. national securities exchanges that Horizon Investments, LLC (“Horizon” or the “Sub-Advisor”) believes exhibit low future expected volatility. The goal of this strategy is to capture upside price movements in rising markets and reduce downside risk when markets decline. To implement this strategy, the Sub-Advisor employs volatility forecasting models to forecast future expected volatility. The strategy is largely quantitative and rules-based, but also includes multiple parameters over which the Sub-Advisor may exercise discretion (including, but not limited to, the number of holdings and the weightings of particular holdings) in connection with its active management of the Fund. Shares of the Fund are listed and trade on the NYSE Arca, Inc. under the ticker symbol “HUSV.” The first day of secondary market trading in shares of the Fund was August 25, 2016.

Performance figures assume reinvestment of all distributions and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. The Fund’s past performance does not predict future performance.

Fund Performance Overview (Unaudited) (Continued)
First Trust Horizon Managed Volatility Developed International ETF (HDMV)
The investment objective of First Trust Horizon Managed Volatility Developed International ETF (the “Fund”) is to provide capital appreciation. Under normal market conditions, the Fund seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in common stocks and depositary receipts of developed market companies listed and traded on non-U.S. exchanges that Horizon Investments, LLC (“Horizon” or the “Sub-Advisor”) believes exhibit low future expected volatility. The term “developed market companies” means those companies (i) whose securities are traded principally on a stock exchange in a developed market country, (ii) with a primary business office in a developed market country, or (iii) that have at least 50% of their assets in, or derive at least 50% of their revenues or profits from, a developed market country.

However, this list may change in response to market and geopolitical events.

Notes to Fund Performance Overview (Unaudited)
Total returns for the periods since inception are calculated from the inception date of each Fund. “Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated.
Each Fund’s per share net asset value (“NAV”) is the value of one share of the Fund and is computed by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of outstanding shares. The price used to calculate market return (“Market Price”) is determined by using the midpoint of the national best bid and offer price (“NBBO”) as of the time that the Fund’s NAV is calculated. Under SEC rules, the NBBO consists of the highest displayed buy and lowest sell prices among the various exchanges trading the Fund at the time the Fund’s NAV is calculated. Prior to January 1, 2019, the price used was the midpoint between the highest bid and the lowest offer on the stock exchange on which shares of the Fund were listed for trading as of the time that the Fund’s NAV was calculated. Since shares of each Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of each Fund is used as a proxy for the secondary market trading price to calculate market returns. NAV and market returns assume that all distributions have been reinvested in each Fund at NAV and Market Price, respectively.
An index is a statistical composite that tracks a specified financial market or sector. Unlike each Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by each Fund. These expenses negatively impact the performance of each Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The total returns presented reflect the reinvestment of dividends on securities in the indices. The returns presented do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of each Fund will vary with changes in market conditions. Shares of each Fund may be worth more or less than their original cost when they are redeemed or sold in the market. Each Fund’s past performance is no guarantee of future performance.

Understanding Your Fund Expenses
January 31, 2023 (Unaudited)
As a shareholder of First Trust Horizon Managed Volatility Domestic ETF, First Trust Horizon Managed Volatility Developed International ETF or First Trust Horizon Managed Volatility Small/Mid ETF (each a “Fund” and collectively, the “Funds”), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs (in U.S. dollars) of investing in the Funds and to compare these costs with the ongoing costs of investing in other funds.
The Example is based on an investment of $1,000 invested at the beginning of the period and held through the six-month period ended January 31, 2023.
Actual Expenses
The first line in the following table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During the Six-Month Period” to estimate the expenses you paid on your account during this six-month period.
Hypothetical Example for Comparison Purposes
The second line in the following table provides information about hypothetical account values and hypothetical expenses based on each Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not each Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Funds and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.
Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs such as brokerage commissions. Therefore, the second line in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

(a) Portfolio securities are categorized based upon their country of incorporation. For a breakdown of the portfolio securities by sector, please see the Fund Performance Overview.
(b) This security is fair valued by the Advisor’s Pricing Committee in accordance with procedures approved by the Trust’s Board of Trustees and in accordance with provisions of the Investment Company Act of 1940 and rules thereunder, as amended. At January 31, 2023, securities noted as such are valued at $39,596,620 or 98.4% of net assets. Certain of these securities are fair valued using a factor provided by a third-party pricing service due to the change in value between the foreign markets’ close and the New York Stock Exchange close exceeding a certain threshold. On days when this threshold is not exceeded, these securities are typically valued at the last sale price on the exchange on which they are principally traded.
(c) This security may be resold to qualified foreign investors and foreign institutional buyers under Regulation S of the Securities Act of 1933, as amended (the “1933 Act”).
(d) This security is exempt from registration upon resale under Rule 144A of the 1933 Act and may be resold in transactions exempt from registration, normally to qualified institutional buyers. This security is not restricted on the foreign exchange where it trades freely without any additional registration. As such, it does not require the additional disclosure required of restricted securities.
(e) Non-income producing security.

First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
1. Organization
First Trust Exchange-Traded Fund III (the “Trust”) is an open-end management investment company organized as a Massachusetts business trust on January 9, 2008, and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended (the “1940 Act”).
The Trust currently consists of seventeen funds that are offering shares. This report covers the following funds (each a “Fund” and collectively, the “Funds”). The shares of each Fund are listed and traded on the NYSE Arca, Inc.
First Trust Horizon Managed Volatility Domestic ETF – (ticker “HUSV”)
First Trust Horizon Managed Volatility Developed International ETF – (ticker “HDMV”)
First Trust Horizon Managed Volatility Small/Mid ETF – (ticker “HSMV”)
HUSV and HDMV are diversified series of the Trust. HSMV is a non-diversified series of the Trust.
Each Fund represents a separate series of shares of beneficial interest in the Trust. Unlike conventional mutual funds, each Fund issues and redeems shares on a continuous basis, at net asset value (“NAV”), only in large blocks of shares known as “Creation Units.”
Each Fund is an actively managed exchange-traded fund. The investment objective of each Fund is to provide capital appreciation.
Under normal market conditions, HUSV seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in common stocks of domestic companies listed and traded on U.S. national securities exchanges that Horizon Investments, LLC (“Horizon” or the “Sub-Advisor”) believes exhibit low future expected volatility.
Under normal market conditions, HDMV seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in common stocks and depositary receipts of developed market companies listed and traded on non-U.S. exchanges that Horizon believes exhibit low future expected volatility.
Under normal market conditions, HSMV seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in small- and/or mid-capitalization common stocks listed and traded on U.S. national securities exchanges that Horizon believes exhibit low future expected volatility.
There can be no assurance that a Fund will achieve its investment objective. The Funds may not be appropriate for all investors.
2. Significant Accounting Policies
The Funds are each considered an investment company and follow accounting and reporting guidance under Financial Accounting Standards Board Accounting Standards Codification Topic 946, “Financial Services-Investment Companies.” The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of the financial statements. The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.
A. Portfolio Valuation
Each Fund’s NAV is determined daily as of the close of regular trading on the New York Stock Exchange (“NYSE”), normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. Foreign securities are priced using data reflecting the earlier closing of the principal markets for those securities. Each Fund’s NAV is calculated by dividing the value of all assets of each Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of shares outstanding.
Each Fund’s investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent readily available market quotations such as last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Pricing Committee of the Funds’ investment advisor, First Trust Advisors L.P. (“First Trust” or the “Advisor”), in accordance with valuation procedures approved by the Trust’s Board of Trustees, and in accordance with provisions of the 1940 Act and rules thereunder. Investments valued by the Advisor’s Pricing Committee, if any, are footnoted as such in the footnotes to the Portfolio of Investments. Each Fund’s investments are valued as follows:
Common stocks, real estate investment trusts (“REITs”) and other equity securities listed on any national or foreign exchange (excluding The Nasdaq Stock Market LLC (“Nasdaq”) and the London Stock Exchange Alternative Investment Market (“AIM”))
Page 29

Notes to Financial Statements (Continued)
First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
are valued at the last sale price on the exchange on which they are principally traded or, for Nasdaq and AIM securities, the official closing price. Securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, at the close of the securities exchange representing the primary exchange for such securities.
Securities trading on foreign exchanges or over-the-counter markets that close prior to the NYSE close may be valued using a systematic fair valuation model provided by a third-party pricing service. If these foreign securities meet certain criteria in relation to the valuation model, their valuation is systematically adjusted to reflect the impact of movement in the U.S. market after the close of the foreign markets.
Securities traded in an over-the-counter market are valued at the mean of their most recent bid and asked price, if available, and otherwise at their last trade price.
Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Advisor’s Pricing Committee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a third-party pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of a Fund’s NAV or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the third-party pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchanges. A variety of factors may be considered in determining the fair value of such securities, including, but not limited to, the following:
1) the last sale price on the exchange on which they are principally traded or, for Nasdaq and AIM securities, the official closing price;
2) the type of security;
3) the size of the holding;
4) the initial cost of the security;
5) transactions in comparable securities;
6) price quotes from dealers and/or third-party pricing services;
7) relationships among various securities;
8) information obtained by contacting the issuer, analysts, or the appropriate stock exchange;
9) an analysis of the issuer’s financial statements;
10) the existence of merger proposals or tender offers that might affect the value of the security; and
11) other relevant factors.
If the securities in question are foreign securities, the following additional information may be considered:
1) the value of similar foreign securities traded on other foreign markets;
2) ADR trading of similar securities;
3) closed-end fund or exchange-traded fund trading of similar securities;
4) foreign currency exchange activity;
5) the trading prices of financial products that are tied to baskets of foreign securities;
6) factors relating to the event that precipitated the pricing problem;
7) whether the event is likely to recur;
8) whether the effects of the event are isolated or whether they affect entire markets, countries or regions; and
9) other relevant factors.
Because foreign markets may be open on different days than the days during which investors may transact in the shares of a Fund, the value of the Fund’s securities may change on the days when investors are not able to transact in the shares of the Fund. The value of securities denominated in foreign currencies is converted into U.S. dollars using exchange rates determined daily as of the close of regular trading on the NYSE.

First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
The Funds are subject to fair value accounting standards that define fair value, establish the framework for measuring fair value and provide a three-level hierarchy for fair valuation based upon the inputs to the valuation as of the measurement date. The three levels of the fair value hierarchy are as follows:
Level 1 – Level 1 inputs are quoted prices in active markets for identical investments. An active market is a market in which transactions for the investment occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:
o Quoted prices for similar investments in active markets.
o Quoted prices for identical or similar investments in markets that are non-active. A non-active market is a market where there are few transactions for the investment, the prices are not current, or price quotations vary substantially either over time or among market makers, or in which little information is released publicly.
o Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).
o Inputs that are derived principally from or corroborated by observable market data by correlation or other means.
Level 3 – Level 3 inputs are unobservable inputs. Unobservable inputs may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.
The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value each Fund’s investments as of January 31, 2023, is included with each Fund’s Portfolio of Investments.
B. Securities Transactions and Investment Income
Securities transactions are recorded as of the trade date. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recorded on the ex-dividend date. Interest income, if any, is recorded daily on the accrual basis.
Withholding taxes and tax reclaims on foreign dividends have been provided for in accordance with each Fund’s understanding of the applicable country’s tax rules and rates.
Distributions received from a Fund’s investments in REITs may be comprised of return of capital, capital gains, and income. The actual character of the amounts received during the year are not known until after the REITs’ fiscal year end. A Fund records the character of distributions received from the REITs during the year based on estimates available. The characterization of distributions received by a Fund may be subsequently revised based on information received from the REITs after their tax reporting periods conclude.
C. Foreign Currency
The books and records of the Funds are maintained in U.S. dollars. Foreign currencies, investments and other assets and liabilities are translated into U.S. dollars at the exchange rates prevailing at the end of the period. Purchases and sales of investments and items of income and expense are translated on the respective dates of such transactions. Unrealized gains and losses on assets and liabilities, other than investments in securities, which result from changes in foreign currency exchange rates have been included in “Net change in unrealized appreciation (depreciation) on foreign currency translation” on the Statements of Operations. Unrealized gains and losses on investments in securities which result from changes in foreign exchange rates are included with fluctuations arising from changes in market price and are included in “Net change in unrealized appreciation (depreciation) on investments” on the Statements of Operations. Net realized foreign currency gains and losses include the effect of changes in exchange rates between trade date and settlement date on investment security transactions, foreign currency transactions and interest and dividends received and are included in “Net realized gain (loss) on foreign currency transactions” on the Statements of Operations. The portion of foreign currency gains and losses related to fluctuations in exchange rates between the initial purchase settlement date and subsequent sale trade date is included in “Net realized gain (loss) on investments” on the Statements of Operations.
D. Dividends and Distributions to Shareholders
Dividends from net investment income, if any, are declared and paid quarterly by each Fund, or as the Board of Trustees may determine from time to time. Distributions of net realized capital gains earned by each Fund, if any, are distributed at least annually.

January 31, 2023 (Unaudited)
Distributions from net investment income and realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These permanent differences are primarily due to the varying treatment of income and gain/loss on portfolio securities held by the Funds and have no impact on net assets or NAV per share. Temporary differences, which arise from recognizing certain items of income, expense and gain/loss in different periods for financial statement and tax purposes, will reverse at some time in the future.
The tax character of distributions paid by each Fund during the fiscal year ended July 31, 2022, was as follows:

E. Income Taxes
Each Fund intends to continue to qualify as a regulated investment company by complying with the requirements under Subchapter M of the Internal Revenue Code of 1986, as amended, which includes distributing substantially all of its net investment income and net realized gains to shareholders. Accordingly, no provision has been made for federal and state income taxes. However, due to the timing and amount of distributions, each Fund may be subject to an excise tax of 4% of the amount by which approximately 98% of each Fund’s taxable income exceeds the distributions from such taxable income for the calendar year.
The Funds are subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. For HUSV and HDMV, taxable years ended 2019, 2020, 2021, and 2022 remain open to federal and state audit. For HSMV, the taxable years ended 2020, 2021, and 2022 remain open to federal and state audit. As of January 31, 2023, management has evaluated the application of these standards to the Funds and has determined that no provision for income tax is required in the Funds’ financial statements for uncertain tax positions.
The Funds intend to utilize provisions of the federal income tax laws, which allow them to carry a realized capital loss forward indefinitely following the year of the loss and offset such loss against any future realized capital gains. The Funds are subject to certain limitations under U.S. tax rules on the use of capital loss carryforwards and net unrealized built-in losses. These limitations apply when there has been a 50% change in ownership. At July 31, 2022, for federal income tax purposes, the Funds had a capital loss carryforward available that is shown in the following table, to the extent provided by regulations, to offset future capital gains.

F. Expenses
Expenses, other than the investment advisory fee and other excluded expenses, are paid by the Advisor (See Note 3).
3. Investment Advisory Fee, Affiliated Transactions and Other Fee Arrangements
First Trust, the investment advisor to the Funds, is a limited partnership with one limited partner, Grace Partners of DuPage L.P., and one general partner, The Charger Corporation. The Charger Corporation is an Illinois corporation controlled by James A. Bowen, Chief Executive Officer of First Trust. First Trust is responsible for supervising the selection and ongoing monitoring of the securities in each Fund’s portfolio, managing the Funds’ business affairs and providing certain administrative services necessary for the management of the Funds.
First Trust is paid an annual unitary management fee for each Fund. Pursuant to the Investment Management Agreement between First Trust and the Trust, First Trust manages the investment of the Funds’ assets and is responsible for the expenses of each Fund, including the cost of transfer agency, sub-advisory, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees payable pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses, which are paid by each respective Fund. Effective November 1, 2022, the annual unitary management fee payable by each Fund to First Trust for these services will be reduced at certain levels of each Fund’s net assets (“breakpoints”) and calculated pursuant to the following schedules:
Breakpoints   HUSV   HSMV
Fund net assets up to and including $2.5 billion   0.7000%   0.80%
Fund net assets greater than $2.5 billion up to and including $5 billion   0.6825%   0.78%
Fund net assets greater than $5 billion up to and including $7.5 billion   0.6650%   0.76%
Fund net assets greater than $7.5 billion up to and including $10 billion   0.6475%   0.74%
Fund net assets greater than $10 billion up to and including $15 billion   0.6300%   0.72%
Fund net assets greater than $15 billion   0.5950%   0.68%
         
Breakpoints   HDMV    
Fund net assets up to and including $2.5 billion   0.80%    
Fund net assets greater than $2.5 billion up to and including $5 billion   0.78%    
Fund net assets greater than $5 billion up to and including $7.5 billion   0.76%    
Fund net assets greater than $7.5 billion up to and including $10 billion   0.74%    
Fund net assets greater than $10 billion   0.72%    
Prior to November 1, 2022, HUSV paid First Trust an annual unitary management fee equal to 0.70% of the Fund’s average daily net assets and HDMV and HSMV each paid First Trust an annual unitary management fee of 0.80% of their average daily net assets. First Trust also provides fund reporting services to the Funds for a flat annual fee in the amount of $9,250, which is covered under the annual unitary management fee.

First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
Horizon serves as the Funds’ sub-advisor and manages each Fund’s portfolio subject to First Trust’s supervision. The Sub-Advisor receives a sub-advisory fee from First Trust equal to 50% of any remaining monthly unitary management fee paid to the Advisor after the average Fund’s expenses accrued during the most recent twelve months are subtracted from the unitary management fee for that month.
The Trust has multiple service agreements with Brown Brothers Harriman & Co. (“BBH”). Under the service agreements, BBH performs custodial, fund accounting, certain administrative services, and transfer agency services for the Funds. As custodian, BBH is responsible for custody of each Fund’s assets. As fund accountant and administrator, BBH is responsible for maintaining the books and records of each Fund’s securities and cash. As transfer agent, BBH is responsible for maintaining shareholder records for each Fund.
Each Trustee who is not an officer or employee of First Trust, any sub-advisor or any of their affiliates (“Independent Trustees”) is paid a fixed annual retainer that is allocated equally among each fund in the First Trust Fund Complex. Each Independent Trustee is also paid an annual per fund fee that varies based on whether the fund is a closed-end or other actively managed fund, a target outcome fund or an index fund.
Additionally, the Lead Independent Trustee and the Chairs of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Independent Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairs rotate every three years. The officers and “Interested” Trustee receive no compensation from the Trust for acting in such capacities.
4. Purchases and Sales of Securities
For the six months ended January 31, 2023, the cost of purchases and proceeds from sales of investment securities for each Fund, excluding short-term investments and in-kind transactions, were as follows:
  Purchases   Sales
First Trust Horizon Managed Volatility Domestic ETF $ 69,806,224   $ 69,867,975
First Trust Horizon Managed Volatility Developed International ETF  18,874,498    19,052,211
First Trust Horizon Managed Volatility Small/Mid ETF  4,650,617    4,570,071
       
For the six months ended January 31, 2023, the cost of in-kind purchases and proceeds from in-kind sales for each Fund were as follows:
  Purchases   Sales
First Trust Horizon Managed Volatility Domestic ETF $ 18,738,399   $ 17,969,065
First Trust Horizon Managed Volatility Developed International ETF  —    5,602,890
First Trust Horizon Managed Volatility Small/Mid ETF  3,172,586    —
5. Creations, Redemptions and Transaction Fees
Each Fund generally issues and redeems its shares in primary market transactions through a creation and redemption mechanism and does not sell or redeem individual shares. Instead, financial entities known as “Authorized Participants” have contractual arrangements with a Fund or one of the Fund’s service providers to purchase and redeem Fund shares directly with the Fund in large blocks of shares known as “Creation Units.” Prior to the start of trading on every business day, a Fund publishes through the National Securities Clearing Corporation (“NSCC”) the “basket” of securities, cash or other assets that it will accept in exchange for a Creation Unit of the Fund’s shares. An Authorized Participant that wishes to effectuate a creation of a Fund’s shares deposits with the Fund the “basket” of securities, cash or other assets identified by the Fund that day, and then receives the Creation Unit of the Fund’s shares in return for those assets. After purchasing a Creation Unit, the Authorized Participant may continue to hold the Fund’s shares or sell them in the secondary market. The redemption process is the reverse of the purchase process: the Authorized Participant redeems a Creation Unit of a Fund’s shares for a basket of securities, cash or other assets. The combination of the creation and redemption process with secondary market trading in a Fund’s shares and underlying securities provides arbitrage opportunities that are designed to help keep the market price of a Fund’s shares at or close to the NAV per share of the Fund.
Each Fund imposes fees in connection with the purchase of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which
Page 34

Notes to Financial Statements (Continued)
First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
the transactions are settled. The price for each Creation Unit will equal the daily NAV per share of a Fund times the number of shares in a Creation Unit, plus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the creation basket.
Each Fund also imposes fees in connection with the redemption of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price received for each Creation Unit will equal the daily NAV per share of a Fund times the number of shares in a Creation Unit, minus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the redemption basket. Investors who use the services of a broker or other such intermediary in addition to an Authorized Participant to effect a redemption of a Creation Unit may also be assessed an amount to cover the cost of such services. The redemption fee charged by a Fund will comply with Rule 22c-2 of the 1940 Act which limits redemption fees to no more than 2% of the value of the shares redeemed.
6. Distribution Plan
The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, each Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. (“FTP”), the distributor of the Funds, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or to provide investor services. FTP may also use this amount to compensate securities dealers or other persons that are Authorized Participants for providing distribution assistance, including broker-dealer and shareholder support and educational and promotional services.
No 12b-1 fees are currently paid by the Funds, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before November 30, 2023.
7. Indemnification
The Trust, on behalf of the Funds, has a variety of indemnification obligations under contracts with its service providers. The Trust’s maximum exposure under these arrangements is unknown. However, the Trust has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.
8. Subsequent Events
Management has evaluated the impact of all subsequent events to the Funds through the date the financial statements were issued and has determined that there were no subsequent events requiring recognition or disclosure in the financial statements that have not already been disclosed.

Proxy Voting Policies and Procedures
A description of the policies and procedures that the Trust uses to determine how to vote proxies and information on how each Fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available (1) without charge, upon request, by calling (800) 988-5891; (2) on each Fund’s website at www.ftportfolios.com; and (3) on the Securities and Exchange Commission’s (“SEC”) website at www.sec.gov.
Portfolio Holdings
Each Fund files portfolio holdings information for each month in a fiscal quarter within 60 days after the end of the relevant fiscal quarter on Form N-PORT. Portfolio holdings information for the third month of each fiscal quarter will be publicly available on the SEC’s website at www.sec.gov. Each Fund’s complete schedule of portfolio holdings for the second and fourth quarters of each fiscal year is included in the semi-annual and annual reports to shareholders, respectively, and is filed with the SEC on Form N-CSR. The semi-annual and annual report for each Fund is available to investors within 60 days after the period to which it relates. Each Fund’s Forms N-PORT and Forms N-CSR are available on the SEC’s website listed above.
Risk Considerations
Risks are inherent in all investing. Certain general risks that may be applicable to a Fund are identified below, but not all of the material risks relevant to each Fund are included in this report and not all of the risks below apply to each Fund. The material risks of investing in each Fund are spelled out in its prospectus, statement of additional information and other regulatory filings. Before investing, you should consider each Fund’s investment objective, risks, charges and expenses, and read each Fund’s prospectus and statement of additional information carefully. You can download each Fund’s prospectus at www.ftportfolios.com or contact First Trust Portfolios L.P. at (800) 621-1675 to request a prospectus, which contains this and other information about each Fund.
Concentration Risk. To the extent that a fund is able to invest a significant percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the fund’s investments more than if the fund were more broadly diversified. A fund that tracks an index will be concentrated to the extent the fund’s corresponding index is concentrated. A concentration makes a fund more susceptible to any single occurrence and may subject the fund to greater market risk than a fund that is more broadly diversified.
Credit Risk. Credit risk is the risk that an issuer of a security will be unable or unwilling to make dividend, interest and/or principal payments when due and the related risk that the value of a security may decline because of concerns about the issuer’s ability to make such payments.
Cyber Security Risk. The funds are susceptible to potential operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause a fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause a fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. In addition, cyber security breaches of a fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, or issuers in which the fund invests, can also subject a fund to many of the same risks associated with direct cyber security breaches.
Defined Outcome Funds Risk. To the extent a fund’s investment strategy is designed to deliver returns tied to the price performance of an underlying ETF, an investor may not realize the returns the fund seeks to achieve if that investor does not hold shares for the entire target outcome period. In the event an investor purchases shares after the first day of the target outcome period or sells shares prior to the end of the target outcome period, the buffer that the fund seeks to provide against a decline in the value of the underlying ETF may not be available, the enhanced returns that the fund seeks to provide (if any) may not be available and the investor may not participate in a gain in the value of the underlying ETF up to the cap for the investor’s investment period. Additionally, the fund will not participate in gains of the underlying ETF above the cap and a shareholder may lose their entire investment. If the fund seeks enhanced returns, there are certain time periods when the value of the fund may fall faster than the value of the underlying ETF, and it is very unlikely that, on any given day during which the underlying ETF share price increases in value, the fund’s share price will increase at the same rate as the enhanced returns sought by the fund, which is designed for an entire target outcome period. Trading flexible exchange options involves risks different from, or possibly greater than, the risks associated with investing directly in securities, such as less liquidity and correlation and valuation risks. A fund may experience substantial downside from specific flexible exchange option positions and certain positions may expire worthless.
Derivatives Risk. To the extent a fund uses derivative instruments such as futures contracts, options contracts and swaps, the fund may experience losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified
Page 36

Additional Information (Continued)
First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
by certain features of the derivative. These risks are heightened when a fund’s portfolio managers use derivatives to enhance the fund’s return or as a substitute for a position or security, rather than solely to hedge (or offset) the risk of a position or security held by the fund.
Equity Securities Risk. To the extent a fund invests in equity securities, the value of the fund’s shares will fluctuate with changes in the value of the equity securities. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant stock market, such as market volatility, or when political or economic events affecting the issuers occur. In addition, common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market.
ETF Risk. The shares of an ETF trade like common stock and represent an interest in a portfolio of securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities, although lack of liquidity in an ETF could result in it being more volatile and ETFs have management fees that increase their costs. Shares of an ETF trade on an exchange at market prices rather than net asset value, which may cause the shares to trade at a price greater than net asset value (premium) or less than net asset value (discount). In times of market stress, decisions by market makers to reduce or step away from their role of providing a market for an ETF’s shares, or decisions by an ETF’s authorized participants that they are unable or unwilling to proceed with creation and/or redemption orders of an ETF’s shares, could result in shares of the ETF trading at a discount to net asset value and in greater than normal intraday bid-ask spreads.
Fixed Income Securities Risk. To the extent a fund invests in fixed income securities, the fund will be subject to credit risk, income risk, interest rate risk, liquidity risk and prepayment risk. Income risk is the risk that income from a fund’s fixed income investments could decline during periods of falling interest rates. Interest rate risk is the risk that the value of a fund’s fixed income securities will decline because of rising interest rates. Liquidity risk is the risk that a security cannot be purchased or sold at the time desired, or cannot be purchased or sold without adversely affecting the price. Prepayment risk is the risk that the securities will be redeemed or prepaid by the issuer, resulting in lower interest payments received by the fund. In addition to these risks, high yield securities, or “junk” bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and the market for high yield securities is generally smaller and less liquid than that for investment grade securities.
Index or Model Constituent Risk. Certain funds may be a constituent of one or more indices or ETF models. As a result, such a fund may be included in one or more index-tracking exchange-traded funds or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving a fund, the size of the fund and the market volatility of the fund. Inclusion in an index could increase demand for the fund and removal from an index could result in outsized selling activity in a relatively short period of time. As a result, a fund’s net asset value could be negatively impacted and the fund’s market price may be significantly below its net asset value during certain periods. In addition, index rebalances may potentially result in increased trading activity in a fund’s shares.
Index Provider Risk. To the extent a fund seeks to track an index, it is subject to Index Provider Risk. There is no assurance that the Index Provider will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, the Index Provider may carry out an unscheduled rebalance or other modification of the Index constituents or weightings, which may increase the fund’s costs. The Index Provider does not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and it does not guarantee that the Index will be calculated in accordance with its stated methodology. Losses or costs associated with any Index Provider errors generally will be borne by the fund and its shareholders.
Investment Companies Risk. To the extent a fund invests in the securities of other investment vehicles, the fund will incur additional fees and expenses that would not be present in a direct investment in those investment vehicles. Furthermore, the fund’s investment performance and risks are directly related to the investment performance and risks of the investment vehicles in which the fund invests.
LIBOR Risk. To the extent a fund invests in floating or variable rate obligations that use the London Interbank Offered Rate (“LIBOR”) as a reference interest rate, it is subject to LIBOR Risk. The United Kingdom’s Financial Conduct Authority, which regulates LIBOR has ceased making LIBOR available as a reference rate over a phase-out period that began December 31, 2021. There is no assurance that any alternative reference rate, including the Secured Overnight Financing Rate (“SOFR”) will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. The unavailability or replacement of LIBOR may affect the value, liquidity or return on certain fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any potential effects of the transition away from LIBOR on the fund or on certain instruments in which the fund invests can be difficult to ascertain, and they may vary depending on a variety of factors, and they could result in losses to the fund.

First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
Management Risk. To the extent that a fund is actively managed, it is subject to management risk. In managing an actively-managed fund’s investment portfolio, the fund’s portfolio managers will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that a fund will meet its investment objective.
Market Risk. Market risk is the risk that a particular security, or shares of a fund in general, may fall in value. Securities held by a fund, as well as shares of a fund itself, are subject to market fluctuations caused by factors such as general economic conditions, political events, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of a fund could decline in value or underperform other investments as a result of the risk of loss associated with these market fluctuations. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on a fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. In February 2022, Russia invaded Ukraine which has caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, and the United States. The hostilities and sanctions resulting from those hostilities could have a significant impact on certain fund investments as well as fund performance. The COVID-19 global pandemic and the ensuing policies enacted by governments and central banks have caused and may continue to cause significant volatility and uncertainty in global financial markets. While the U.S. has resumed “reasonably” normal business activity, many countries continue to impose lockdown measures. Additionally, there is no guarantee that vaccines will be effective against emerging variants of the disease. These events also adversely affect the prices and liquidity of a fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of a fund’s shares and result in increased market volatility. During any such events, a fund’s shares may trade at increased premiums or discounts to their net asset value and the bid/ask spread on a fund’s shares may widen.
Non-U.S. Securities Risk. To the extent a fund invests in non-U.S. securities, it is subject to additional risks not associated with securities of domestic issuers. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to: possible adverse political, social or economic developments; restrictions on foreign investment or exchange of securities; capital controls; lack of liquidity; currency exchange rates; excessive taxation; government seizure of assets; the imposition of sanctions by foreign governments; different legal or accounting standards; and less government supervision and regulation of exchanges in foreign countries. Investments in non-U.S. securities may involve higher costs than investments in U.S. securities, including higher transaction and custody costs, as well as additional taxes imposed by non-U.S. governments. These risks may be heightened for securities of companies located, or with significant operations, in emerging market countries.
Operational Risk. Each fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of a fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. Each fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect a fund’s ability to meet its investment objective. Although the funds and the funds’ investment advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.
Passive Investment Risk. To the extent a fund seeks to track an index, the fund will invest in the securities included in, or representative of, the index regardless of their investment merit. A fund generally will not attempt to take defensive positions in declining markets.
Preferred Securities Risk. Preferred securities combine some of the characteristics of both common stocks and bonds. Preferred securities are typically subordinated to bonds and other debt securities in a company’s capital structure in terms of priority to corporate income, subjecting them to greater credit risk than those debt securities. Generally, holders of preferred securities have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may obtain limited rights. In certain circumstances, an issuer of preferred securities may defer payment on the securities and, in some cases, redeem the securities prior to a specified date. Preferred securities may also be substantially less liquid than other securities, including common stock.
Valuation Risk. The valuation of certain securities may carry more risk than that of common stock. Uncertainties in the conditions of the financial markets, unreliable reference data, lack of transparency and inconsistency of valuation models and processes may lead to inaccurate asset pricing. A fund may hold investments in sizes smaller than institutionally sized round lot positions (sometimes referred to as odd lots). However, third-party pricing services generally provide evaluations on the basis of institutionally-sized round lots. If a fund sells certain of its investments in an odd lot transaction, the sale price may be less than the value at which such securities
Page 38

Additional Information (Continued)
First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
have been held by the fund. Odd lots often trade at lower prices than institutional round lots. There is no assurance that the fund will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to the fund.

The Board of Trustees of First Trust Exchange-Traded Fund III (the “Trust”), including the Independent Trustees, unanimously approved the amendment (as applicable to a specific Fund, the “Advisory Agreement Amendment” and collectively, the “Advisory Agreement Amendments”) of the Investment Management Agreements (as applicable to a specific Fund, the “Advisory Agreement” and collectively, the “Advisory Agreements”) with First Trust Advisors L.P. (the “Advisor”) and the amendment (the “Sub-Advisory Agreement Amendment” and together with the Advisory Agreement Amendments, the “Amendments”) of the Investment Sub-Advisory Agreement (the “Sub-Advisory Agreement” and together with the Advisory Agreements, the “Agreements”) among the Trust, the Advisor and Horizon Investments, LLC (the “Sub-Advisor”) on behalf of the following three series of the Trust (each a “Fund” and collectively, the “Funds”):
First Trust Horizon Managed Volatility Domestic ETF (HUSV)
First Trust Horizon Managed Volatility Developed International ETF (HDMV)
First Trust Horizon Managed Volatility Small/Mid ETF (HSMV)
The Board approved the applicable Amendments for each Fund at a meeting held on October 24, 2022.  As part of the review process, the Board reviewed information and had preliminary discussions with the Advisor regarding the proposed Amendments at meetings held on April 18, 2022, June 12–13, 2022 and September 18–19, 2022.  Following those preliminary discussions, the Board requested and received information from the Advisor regarding the proposed Amendments, and that information was considered at an executive session of the Independent Trustees and their counsel held prior to the October 24, 2022 meeting, as well as at the October meeting.
In reviewing the Advisory Agreement Amendment for each Fund, the Board considered that the purpose of the Advisory Agreement Amendments is to modify the unitary fee rate for each Fund under the applicable Advisory Agreement by introducing a breakpoint schedule pursuant to which the unitary fee rate paid by each Fund to the Advisor will be reduced as assets of such Fund meet certain thresholds.  In reviewing the Sub-Advisory Agreement Amendment for each Fund, the Board considered that the purpose of the Sub-Advisory Agreement Amendment is to modify the sub-advisory fee rate for each Fund under the Sub-Advisory Agreement to reflect the modification of the unitary fee rate schedule under the applicable Advisory Agreement Amendment.  The Board noted the Advisor’s representations that the quality and quantity of the services provided to each Fund by the Advisor under the applicable Advisory Agreement and by the Sub-Advisor under the Sub-Advisory Agreement will not be reduced or modified as a result of the applicable Advisory Agreement Amendment and the Sub-Advisory Agreement Amendment, and that the obligations of the Advisor under each Advisory Agreement and the obligations of the Sub-Advisor under the Sub-Advisory Agreement will remain the same in all respects.
The Board noted that it, including the Independent Trustees, last approved the continuation of the applicable Advisory Agreement for each Fund for a one-year period ending June 30, 2023 at a meeting held on June 12–13, 2022.  The Board noted that in connection with such approval it had determined for each Fund, based upon the information provided, that the terms of the applicable Advisory Agreement were fair and reasonable and that the continuation of the applicable Advisory Agreement was in the best interests of the Fund in light of the nature, extent and quality of the services provided and such other matters as the Board considered to be relevant in the exercise of its business judgment.
The Board also noted that it, including the Independent Trustees, approved the Sub-Advisory Agreement for HSMV, HUSV and HDMV for an initial two-year period ending December 6, 2023, March 31, 2024 and April 11, 2024, respectively, at a meeting held on September 12–13, 2021 and that shareholders of each of HSMV, HUSV and HDMV approved the Sub-Advisory Agreement for their respective Fund at meetings held on December 6, 2021, March 31, 2022 and April 11, 2022, respectively.  The Board noted that in connection with its approval it had determined for each Fund, based upon the information provided, that the terms of the Sub-Advisory Agreement were fair and reasonable and that the approval of the Sub-Advisory Agreement was in the best interests of the Fund in light of the nature, extent and quality of the services provided and such other matters as the Board considered to be relevant in the exercise of its business judgment.

(“First Trust” or the “Advisor”) and its representatives, taking into account the information currently available to them. Forward-looking statements include all statements that do not relate solely to current or historical fact. For example, forward-looking statements include the use of words such as “anticipate,” “estimate,” “intend,” “expect,” “believe,” “plan,” “may,” “should,” “would” or other words that convey uncertainty of future events or outcomes.
Forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of any series of First Trust Exchange-Traded Fund III (the “Trust”) described in this report (each such series is referred to as a “Fund” and collectively, the “Funds”) to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

Performance and Risk Disclosure
There is no assurance that any Fund described in this report will achieve its investment objectives. Each Fund is subject to market risk, which is the possibility that the market values of securities owned by the Fund will decline and that the value of the Fund’s shares may therefore be less than what you paid for them. Accordingly, you can lose money by investing in a Fund. See “Risk Considerations” in the Additional Information section of this report for a discussion of certain other risks of investing in the Funds.
Performance data quoted represents past performance, which is no guarantee of future results, and current performance may be lower or higher than the figures shown. For the most recent month-end performance figures, please visit www.ftportfolios.com or speak with your financial advisor. Investment returns, net asset value and share price will fluctuate and Fund shares, when sold, may be worth more or less than their original cost.
The Advisor may also periodically provide additional information on Fund performance on each Fund’s web page at www.ftportfolios.com.

Shareholder Letter
First Trust Exchange-Traded Fund III
Semi-Annual Letter from the Chairman and CEO
January 31, 2023
Dear Shareholders,
First Trust is pleased to provide you with the semi-annual report for certain series of First Trust Exchange-Traded Fund III (the “Funds”), which contains detailed information about the Funds for the six-month period ended January 31, 2023.
Given recent inflation data, the Federal Reserve’s (the “Fed”) monetary policy remains front and center in most discussions regarding the outlook of the U.S. economy. Annual revisions to the Consumer Price Index released on February 10, 2023, showed that prices climbed at a 3.3% annual rate in the last three months of 2022, not the 1.8% rate reported four weeks prior, according to Brian Wesbury, Chief Economist at First Trust. Additionally, “core” inflation, which excludes volatile food and energy prices, was also revised upwards from 3.1% to 4.3% over the period. Furthermore, January’s 2023 jobs data came in better than expected, with non-farm payroll employment rising by 517,000. It is precisely this situation: stubbornly high inflation, strong jobs growth and increasing interest rates, which has many pundits debating whether the typical U.S. consumer can remain healthy enough to help ward off an economic recession.
As many investors know, the consumer is an essential driver of economic growth in the U.S. On average, over the 15-year period ended October 1, 2022, consumer spending accounted for 67.8% of the U.S. gross domestic product (“GDP”). Crucially, recent data regarding consumer health has been mixed, in my opinion. On one hand, the Commerce Department reported that in December 2022, the U.S. savings rate rose to its highest level in seven months, coming in at 3.4%. On the other hand, while December’s savings rate was a welcome reversal from the declines suffered throughout 2021 and 2022, it could indicate that consumers are beginning to pull back on discretionary spending amidst a cloudier economic outlook, according to Bloomberg. Recent data shows that the average interest rate on U.S. credit cards rose to 19.07% in the fourth quarter of 2022, its highest level in over 50 years. Additionally, U.S. credit card debt reached a record $930.6 billion in the fourth quarter, jumping 18.5% year-over-year. Even so, debt service payments accounted for just 9.75% of disposable personal income in the third quarter of 2022. This figure is higher than its historic low of 8.33% set in 2021 but is also well below its peak of 13.17% set in 2007. In my view, it is worth keeping an eye on debt service payments. If higher payments lead to a decline in discretionary spending, it could negatively impact GDP.
I would like to take a moment to remind you that even though nearly three years have passed since the World Health Organization initially declared the coronavirus outbreak a global pandemic, the economic impact of worldwide lockdowns and the subsequent governmental stimulus is still very real. China, for example, only recently dropped its requirement that incoming travelers must quarantine before entering the country. In addition, the global economy has yet to fully absorb the impact of the fiscal policies enacted to jump start consumer spending in 2020, in my view. As evidence of this, each of the countries that comprise the G-10 currently has a headline inflation rate that stands well above its stated target. Central banks likely have more work to do, in my opinion.
Thank you for giving First Trust the opportunity to play a role in your financial future. We value our relationship with you and will report on the Funds again in six months.
Sincerely,
James A. Bowen
Chairman of the Board of Trustees
Chief Executive Officer of First Trust Advisors L.P.

Fund Performance Overview (Unaudited) (Continued)
First Trust California Municipal High Income ETF (FCAL) (Continued)

Performance figures assume reinvestment of all distributions and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. The Fund’s past performance does not predict future performance.

Performance in municipal bonds investment strategies can be impacted from the benefits of purchasing odd lot positions. The impact of these investments can be particularly meaningful when funds have limited assets under management and may not be a sustainable source of performance as a fund grows in size. 
Frequency Distribution of Discounts and Premiums
Information showing the number of days the market price of the Fund’s shares was greater (at a premium) and less (at a discount) than the Fund’s net asset value for the most recently completed year, and the most recently completed calendar quarters since that year (or life of the Fund, if shorter), is available at https://www.ftportfolios.com/Retail/etf/home.aspx.

Notes to Fund Performance Overview (Unaudited)
Total returns for the periods since inception are calculated from the inception date of each Fund. “Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated. The total returns would have been lower if certain fees had not been waived by the Advisor.
Each Fund’s per share net asset value (“NAV”) is the value of one share of the Fund and is computed by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of outstanding shares. The price used to calculate market return (“Market Price”) is determined by using the midpoint of the national best bid and offer price (“NBBO”) as of the time that the Fund’s NAV is calculated. Under SEC rules, the NBBO consists of the highest displayed buy and lowest sell prices among the various exchanges trading the Fund at the time the Fund’s NAV is calculated. Prior to January 1, 2019, the price used was the midpoint between the highest bid and the lowest offer on the stock exchange on which shares of the Fund were listed for trading as of the time that the Fund’s NAV was calculated. Since shares of each Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of each Fund is used as a proxy for the secondary market trading price to calculate market returns. NAV and market returns assume that all distributions have been reinvested in each Fund at NAV and Market Price, respectively.
An index is a statistical composite that tracks a specified financial market or sector. Unlike each Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by each Fund. These expenses negatively impact the performance of each Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The total returns presented reflect the reinvestment of dividends on securities in the indices. The returns presented do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of each Fund will vary with changes in market conditions. Shares of each Fund may be worth more or less than their original cost when they are redeemed or sold in the market. Each Fund’s past performance is no guarantee of future performance.

First Trust Exchange-Traded Fund III
Understanding Your Fund Expenses
January 31, 2023 (Unaudited)
As a shareholder of First Trust California Municipal High Income ETF or First Trust New York Municipal High Income ETF (each a “Fund” and collectively, the “Funds”), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs of investing in the Funds and to compare these costs with the ongoing costs of investing in other funds.
The Example is based on an investment of $1,000 invested at the beginning of the period and held through the six-month period ended January 31, 2023.
Actual Expenses
The first line in the following table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During the Six-Month Period” to estimate the expenses you paid on your account during this six-month period.
Hypothetical Example for Comparison Purposes
The second line in the following table provides information about hypothetical account values and hypothetical expenses based on each Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not each Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Funds and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.
Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs such as brokerage commissions. Therefore, the second line in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

(a) This security, sold within the terms of a private placement memorandum, is exempt from registration upon resale under Rule 144A of the Securities Act of 1933, as amended, and may be resold in transactions exempt from registration, normally to qualified institutional buyers. Pursuant to procedures adopted by the Trust’s Board of Trustees, this security has been determined to be liquid by First Trust Advisors L.P. (the “Advisor”). Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security specific factors and assumptions, which require subjective judgment. At January 31, 2023, securities noted as such amounted to $104,548 or 0.8% of net assets.
(b) Variable Rate Demand bond. Interest rate is reset periodically by the agent based on current market conditions.

Notes to Financial Statements
First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
1. Organization
First Trust Exchange-Traded Fund III (the “Trust”) is an open-end management investment company organized as a Massachusetts business trust on January 9, 2008, and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended (the “1940 Act”).
The Trust currently consists of seventeen funds that are offering shares. This report covers the following funds, (each a “Fund” and collectively, the “Funds”):
First Trust California Municipal High Income ETF – (The Nasdaq Stock Market LLC ticker “FCAL”)
First Trust New York Municipal High Income ETF – (NYSE Arca, Inc. ticker “FMNY”)
FCAL is a diversified series of the Trust. FMNY is a non-diversified series of the Trust.
Each Fund represents a separate series of shares of beneficial interest in the Trust. Unlike conventional mutual funds, each Fund issues and redeems shares on a continuous basis, at net asset value (“NAV”), only in large blocks of shares known as “Creation Units.”
Each Fund is an actively managed exchange-traded fund. The primary investment objective of each Fund is to seek to provide current income that is exempt from regular federal income taxes and, for FCAL, California income taxes and, for FMNY, New York income taxes. The secondary investment objective of each Fund is long-term capital appreciation. Under normal market conditions, each Fund seeks to achieve its investment objectives by investing at least 80% of its net assets (including investment borrowings) in municipal debt securities that pay interest that is exempt from regular federal income taxes and, for FCAL, California income taxes and, for FMNY, New York State and New York City income taxes. There can be no assurance that a Fund will achieve its investment objectives. The Funds may not be appropriate for all investors.
2. Significant Accounting Policies
The Funds are each considered an investment company and follow accounting and reporting guidance under Financial Accounting Standards Board Accounting Standards Codification Topic 946, “Financial Services-Investment Companies.” The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of the financial statements. The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.
A. Portfolio Valuation
Each Fund’s NAV is determined daily as of the close of regular trading on the New York Stock Exchange (“NYSE”), normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. Domestic debt securities are priced using data reflecting the earlier closing of the principal markets for those securities. Each Fund’s NAV is calculated by dividing the value of all assets of each Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of shares outstanding.
Each Fund’s investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent readily available market quotations such as last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Pricing Committee of the Funds’ investment advisor, First Trust Advisors L.P. (“First Trust” or the “Advisor”), in accordance with valuation procedures approved by the Trust’s Board of Trustees, and in accordance with provisions of the 1940 Act and rules thereunder. Investments valued by the Advisor’s Pricing Committee, if any, are footnoted as such in the footnotes to the Portfolio of Investments. Each Fund’s investments are valued as follows:
Municipal securities and other debt securities are fair valued on the basis of fair valuations provided by a third-party pricing service approved by the Advisor’s Pricing Committee, which may use the following valuation inputs when available:
1) benchmark yields;
2) reported trades;
3) broker/dealer quotes;
4) issuer spreads;
5) benchmark securities;
6) bids and offers; and
7) reference data including market research publications.
Page 26

Notes to Financial Statements (Continued)
First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but a Fund may hold or transact in such securities in smaller, odd lot sizes. Odd lots may trade at lower prices than institutional round lots.
Exchange-traded futures contracts are valued at the closing price in the market where such contracts are principally traded. If no closing price is available, exchange-traded futures contracts are valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price.
Fixed income and other debt securities having a remaining maturity of sixty days or less when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discounts (amortized cost), provided the Advisor’s Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of the determination. Factors that may be considered in determining the appropriateness of the use of amortized cost include, but are not limited to, the following:
1) the credit conditions in the relevant market and changes thereto;
2) the liquidity conditions in the relevant market and changes thereto;
3) the interest rate conditions in the relevant market and changes thereto (such as significant changes in interest rates);
4) issuer-specific conditions (such as significant credit deterioration); and
5) any other market-based data the Advisor’s Pricing Committee considers relevant. In this regard, the Advisor’s Pricing Committee may use last-obtained market-based data to assist it when valuing portfolio securities using amortized cost.
Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Advisor’s Pricing Committee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended (the “1933 Act”)) for which a third-party pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of a Fund’s NAV or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the third-party pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchanges. A variety of factors may be considered in determining the fair value of such securities, including, but not limited to, the following:
1) the fundamental business data relating to the issuer;
2) an evaluation of the forces which influence the market in which these securities are purchased and sold;
3) the type, size and cost of the security;
4) the financial statements of the issuer;
5) the credit quality and cash flow of the issuer, based on the Advisor’s or external analysis;
6) the information as to any transactions in or offers for the security;
7) the price and extent of public trading in similar securities (or equity securities) of the issuer/borrower, or comparable companies;
8) the coupon payments;
9) the quality, value and salability of collateral, if any, securing the security; and
10) other relevant factors.
The Funds are subject to fair value accounting standards that define fair value, establish the framework for measuring fair value and provide a three-level hierarchy for fair valuation based upon the inputs to the valuation as of the measurement date. The three levels of the fair value hierarchy are as follows:
Level 1 – Level 1 inputs are quoted prices in active markets for identical investments. An active market is a market in which transactions for the investment occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:
o Quoted prices for similar investments in active markets.
Page 27

Notes to Financial Statements (Continued)
First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
o Quoted prices for identical or similar investments in markets that are non-active. A non-active market is a market where there are few transactions for the investment, the prices are not current, or price quotations vary substantially either over time or among market makers, or in which little information is released publicly.
o Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).
o Inputs that are derived principally from or corroborated by observable market data by correlation or other means.
Level 3 – Level 3 inputs are unobservable inputs. Unobservable inputs may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.
The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value each Fund’s investments as of January 31, 2023, is included with each Fund’s Portfolio of Investments.
B. Securities Transactions and Investment Income
Securities transactions are recorded as of the trade date. Realized gains and losses from securities transactions are recorded on the identified cost basis. Interest income is recorded daily on the accrual basis. Amortization of premiums and accretion of discounts are recorded using the effective interest method.
C. Restricted Securities
FCAL invests in restricted securities, which are securities that may not be offered for public sale without first being registered under the 1933 Act. Prior to registration, restricted securities may only be resold in transactions exempt from registration under Rule 144A under the 1933 Act, normally to qualified institutional buyers. As of January 31, 2023, FCAL held restricted securities as shown in the following table that the Advisor has deemed illiquid pursuant to procedures adopted by the Trust’s Board of Trustees. Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security-specific factors and assumptions, which require subjective judgment. FCAL does not have the right to demand that such securities be registered. These securities are valued according to the valuation procedures as stated in the Portfolio Valuation note (Note 2A) and are not expressed as a discount to the carrying value of a comparable unrestricted security. There are no unrestricted securities with the same maturity dates and yields for these issuers.

D. Futures Contracts
The Funds may purchase or sell (i.e., are long or short) exchange-listed futures contracts to hedge against changes in interest rates (interest rate risk). Futures contracts are agreements between the Funds and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and at a specified date. Depending on the terms of the contract, futures contracts are settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date. Open futures contracts can also be closed out prior to settlement by entering into an offsetting transaction in a matching futures contract. If the Funds are not able to enter into an offsetting transaction, the Funds will continue to be required to maintain margin deposits on the futures contract. When the contract is closed or expires, the Funds record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed or expired. This gain or loss is included in “Net realized gain (loss) on futures contracts” on the Statements of Operations.
Upon entering into a futures contract, the Funds must deposit funds, called margin, with its custodian in the name of the clearing broker equal to a specified percentage of the current value of the contract. Open futures contracts are marked to market daily with the change in value recognized as a component of “Net change in unrealized appreciation (depreciation) on futures contracts” on the Statements of Operations. This daily fluctuation in the value of the contracts is also known as variation margin and is included in “Variation margin” payable or receivable on the Statements of Assets and Liabilities.

If market conditions change unexpectedly, the Funds may not achieve the anticipated benefits of the futures contract and may realize a loss. The use of futures contracts involves the risk of imperfect correlation in movements in the price of the futures contracts, interest rates and the underlying instruments.
Restricted cash segregated as collateral for futures contracts in the amounts of $160,100 and $2,750 for FCAL and FMNY, respectively, is shown as “Cash segregated as collateral for open futures contracts” on the Statements of Assets and Liabilities.
E. Dividends and Distributions to Shareholders
Dividends from net investment income, if any, are declared and paid monthly by each Fund, or as the Board of Trustees may determine from time to time. Distributions of net realized capital gains earned by each Fund, if any, are distributed at least annually.
Distributions from net investment income and realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These permanent differences are primarily due to the varying treatment of income and gain/loss on portfolio securities held by the Funds and have no impact on net assets or NAV per share. Temporary differences, which arise from recognizing certain items of income, expense and gain/loss in different periods for financial statement and tax purposes, will reverse at some time in the future.
The tax character of distributions paid by each Fund during the fiscal year ended July 31, 2022, was as follows:
  Distributions

F. Income Taxes
Each Fund intends to continue to qualify as a regulated investment company by complying with the requirements under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), which includes distributing substantially all of its net investment income and net realized gains to shareholders. Accordingly, no provision has been made for federal and state income taxes. However, due to the timing and amount of distributions, each Fund may be subject to an excise tax of 4% of the amount by which approximately 98% of each Fund’s taxable income exceeds the distributions from such taxable income for the calendar year.
In addition, each Fund intends to invest in municipal securities to allow it to pay shareholders “exempt dividends” as defined in the Code.
The Funds are subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. For FCAL, taxable years ended 2019, 2020, 2021, and 2022 remain open to federal and state audit. For FMNY, the taxable period ended 2021 and the taxable year ended 2022 remain open to federal and state audit. As of January 31, 2023, management has evaluated the application of these standards to the Funds and has determined that no provision for income tax is required in the Funds’ financial statements for uncertain tax positions.
The Funds intend to utilize provisions of the federal income tax laws, which allow them to carry a realized capital loss forward indefinitely following the year of the loss and offset such loss against any future realized capital gains. The Funds are subject to certain limitations under U.S. tax rules on the use of capital loss carryforwards and net unrealized built-in losses. These limitations apply when there has been a 50% change in ownership. At July 31, 2022, for federal income tax purposes, each applicable Fund had a capital loss carryforward available that is shown in the table below, to the extent provided by regulations, to offset future capital gains.

G. Expenses
Expenses, other than the investment advisory fee and other excluded expenses, are paid by the Advisor (See Note 3).
3. Investment Advisory Fee, Affiliated Transactions and Other Fee Arrangements
First Trust, the investment advisor to the Funds, is a limited partnership with one limited partner, Grace Partners of DuPage L.P., and one general partner, The Charger Corporation. The Charger Corporation is an Illinois corporation controlled by James A. Bowen, Chief Executive Officer of First Trust. First Trust is responsible for the selection and ongoing monitoring of the securities in each Fund’s portfolio, managing the Funds’ business affairs and providing certain administrative services necessary for the management of the Funds.
Pursuant to the Investment Management Agreements between the Trust and the Advisor, First Trust manages the investment of the Funds’ assets and is responsible for the Funds’ expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreements, interest, taxes, acquired fund fees and expenses, if any, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses. Effective November 1, 2022, the annual unitary management fee payable by each Fund to First Trust for these services will be reduced at certain levels of each Fund’s net assets (“breakpoints”) and calculated pursuant to the following schedule, provided that FMNY is not eligible for any breakpoints until the termination of the Fee Waiver Agreement discussed below.
Breakpoints  
Fund net assets up to and including $2.5 billion 0.65000%
Fund net assets greater than $2.5 billion up to and including $5 billion 0.63375%
Fund net assets greater than $5 billion up to and including $7.5 billion 0.61750%
Fund net assets greater than $7.5 billion up to and including $10 billion 0.60125%
Fund net assets greater than $10 billion 0.58500%
Prior to November 1, 2022, First Trust was paid an annual unitary management fee equal to 0.65% of each Fund’s average daily net assets. First Trust also provides fund reporting services to each Fund for a flat annual fee in the amount of $9,250, which is covered under the annual unitary management fee.
The Trust’s Board of Trustees and the Advisor have entered into Fee Waiver Agreements for the Funds pursuant to which the Advisor contractually agreed to waive management fees of 0.15% of average daily net assets until November 30, 2022 and May 11, 2023, for FCAL and FMNY, respectively. As of November 30, 2022, the Fee Waiver Agreement for FCAL terminated. The Fee Waiver Agreement for FMNY may be terminated by action of the Trust’s Board of Trustees at any time upon 60 days’ written notice by the Trust on behalf of FMNY or by the Advisor only after May 11, 2023. First Trust does not have the right to recover the fees waived

under the Fee Waiver Agreements. During the six months ended January 31, 2023, the Advisor waived fees of $57,858 and $8,456 for FCAL and FMNY, respectively.
The Trust has multiple service agreements with Brown Brothers Harriman & Co. (“BBH”). Under the service agreements, BBH performs custodial, fund accounting, certain administrative services, and transfer agency services for the Funds. As custodian, BBH is responsible for custody of the Funds’ assets. As fund accountant and administrator, BBH is responsible for maintaining the books and records of the Funds’ securities and cash. As transfer agent, BBH is responsible for maintaining shareholder records for the Funds.
Each Trustee who is not an officer or employee of First Trust, any sub-advisor or any of their affiliates (“Independent Trustees”) is paid a fixed annual retainer that is allocated equally among each fund in the First Trust Fund Complex. Each Independent Trustee is also paid an annual per fund fee that varies based on whether the fund is a closed-end or other actively managed fund, a target outcome fund or an index fund.
Additionally, the Lead Independent Trustee and the Chairs of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Independent Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairs rotate every three years. The officers and “Interested” Trustee receive no compensation from the Trust for acting in such capacities.
4. Purchases and Sales of Securities
For the six months ended January 31, 2023, the cost of purchases and proceeds from sales of investment securities for each Fund, excluding short-term investments and in-kind transactions, were as follows:
  Purchases   Sales
First Trust California Municipal High Income ETF $ 35,568,936   $ 44,611,498
First Trust New York Municipal High Income ETF  4,606,382    2,472,786
       
For the six months ended January 31, 2023, the Funds had no in-kind transactions.

The Funds do not have the right to offset financial assets and liabilities related to futures contracts on the Statements of Assets and Liabilities.
6. Creations, Redemptions and Transaction Fees
Each Fund generally issues and redeems its shares in primary market transactions through a creation and redemption mechanism and does not sell or redeem individual shares. Instead, financial entities known as “Authorized Participants” have contractual arrangements with a Fund or one of the Fund’s service providers to purchase and redeem Fund shares directly with the Fund in large blocks of shares known as “Creation Units.” Prior to the start of trading on every business day, a Fund publishes through the National Securities Clearing Corporation (“NSCC”) the “basket” of securities, cash or other assets that it will accept in exchange for a Creation Unit of the Fund’s shares. An Authorized Participant that wishes to effectuate a creation of a Fund’s shares deposits with the Fund the “basket” of securities, cash or other assets identified by the Fund that day, and then receives the Creation Unit of the Fund’s shares in return for those assets. After purchasing a Creation Unit, the Authorized Participant may continue to hold the Fund’s shares or sell them in the secondary market. The redemption process is the reverse of the purchase process: the Authorized Participant redeems a Creation Unit of a Fund’s shares for a basket of securities, cash or other assets. The combination of the creation and redemption process with secondary market trading in a Fund’s shares and underlying securities provides arbitrage opportunities that are designed to help keep the market price of a Fund’s shares at or close to the NAV per share of the Fund.
Each Fund imposes fees in connection with the purchase of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price for each Creation Unit will equal the daily NAV per share of a Fund times the number of shares in a Creation Unit, plus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the creation basket.
Each Fund also imposes fees in connection with the redemption of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price received for each Creation Unit will equal the daily NAV per share of a Fund times the number of shares in a Creation Unit, minus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the redemption basket. Investors who use the services of a broker or other such intermediary in addition to an Authorized Participant to effect a redemption of a Creation Unit may also be assessed an amount to cover the cost of such services. The redemption fee charged by a Fund will comply with Rule 22c-2 of the 1940 Act which limits redemption fees to no more than 2% of the value of the shares redeemed.
7. Distribution Plan
The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, each Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. (“FTP”), the distributor of the Funds, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or to provide investor services. FTP may also use this amount to compensate securities dealers or other persons that are Authorized Participants for providing distribution assistance, including broker-dealer and shareholder support and educational and promotional services.

No 12b-1 fees are currently paid by the Funds, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before November 30, 2023.
8. Borrowings
The Trust, on behalf of FCAL, along with First Trust Series Fund and First Trust Exchange-Traded Fund IV have a $305 million Credit Agreement with The Bank of Nova Scotia (“Scotia”) as administrative agent for a group of lenders. Prior to October 30, 2022, the commitment amount was $280 million. Scotia charges a commitment fee of 0.25% of the daily amount of the excess of the commitment amount over the outstanding principal balance of the loans and an agency fee. First Trust allocates the commitment fee and agency fee amongst the funds that have access to the credit line. To the extent that the Fund accesses the credit line, there would also be an interest fee charged. The Fund did not have any borrowings outstanding during the six months ended January 31, 2023.
9. Indemnification
The Trust, on behalf of the Funds, has a variety of indemnification obligations under contracts with its service providers. The Trust’s maximum exposure under these arrangements is unknown. However, the Trust has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.
10. Subsequent Events
Management has evaluated the impact of all subsequent events to the Funds through the date the financial statements were issued and has determined that there was the following subsequent event:
Effective March 1, 2023, the credit agreement with Scotia was amended, and the maximum commitment amount changed from $305,000,000 to $550,000,000.

Proxy Voting Policies and Procedures
A description of the policies and procedures that the Trust uses to determine how to vote proxies and information on how each Fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available (1) without charge, upon request, by calling (800) 988-5891; (2) on each Fund’s website at www.ftportfolios.com; and (3) on the Securities and Exchange Commission’s (“SEC”) website at www.sec.gov.
Portfolio Holdings
Each Fund files portfolio holdings information for each month in a fiscal quarter within 60 days after the end of the relevant fiscal quarter on Form N-PORT. Portfolio holdings information for the third month of each fiscal quarter will be publicly available on the SEC’s website at www.sec.gov. Each Fund’s complete schedule of portfolio holdings for the second and fourth quarters of each fiscal year is included in the semi-annual and annual reports to shareholders, respectively, and is filed with the SEC on Form N-CSR. The semi-annual and annual report for each Fund is available to investors within 60 days after the period to which it relates. Each Fund’s Forms N-PORT and Forms N-CSR are available on the SEC’s website listed above.
Risk Considerations
Risks are inherent in all investing. Certain general risks that may be applicable to a Fund are identified below, but not all of the material risks relevant to each Fund are included in this report and not all of the risks below apply to each Fund. The material risks of investing in each Fund are spelled out in its prospectus, statement of additional information and other regulatory filings. Before investing, you should consider each Fund’s investment objective, risks, charges and expenses, and read each Fund’s prospectus and statement of additional information carefully. You can download each Fund’s prospectus at www.ftportfolios.com or contact First Trust Portfolios L.P. at (800) 621-1675 to request a prospectus, which contains this and other information about each Fund.
Concentration Risk. To the extent that a fund is able to invest a significant percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the fund’s investments more than if the fund were more broadly diversified. A fund that tracks an index will be concentrated to the extent the fund’s corresponding index is concentrated. A concentration makes a fund more susceptible to any single occurrence and may subject the fund to greater market risk than a fund that is more broadly diversified.
Credit Risk. Credit risk is the risk that an issuer of a security will be unable or unwilling to make dividend, interest and/or principal payments when due and the related risk that the value of a security may decline because of concerns about the issuer’s ability to make such payments.
Cyber Security Risk. The funds are susceptible to potential operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause a fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause a fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. In addition, cyber security breaches of a fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, or issuers in which the fund invests, can also subject a fund to many of the same risks associated with direct cyber security breaches.
Defined Outcome Funds Risk. To the extent a fund’s investment strategy is designed to deliver returns tied to the price performance of an underlying ETF, an investor may not realize the returns the fund seeks to achieve if that investor does not hold shares for the entire target outcome period. In the event an investor purchases shares after the first day of the target outcome period or sells shares prior to the end of the target outcome period, the buffer that the fund seeks to provide against a decline in the value of the underlying ETF may not be available, the enhanced returns that the fund seeks to provide (if any) may not be available and the investor may not participate in a gain in the value of the underlying ETF up to the cap for the investor’s investment period. Additionally, the fund will not participate in gains of the underlying ETF above the cap and a shareholder may lose their entire investment. If the fund seeks enhanced returns, there are certain time periods when the value of the fund may fall faster than the value of the underlying ETF, and it is very unlikely that, on any given day during which the underlying ETF share price increases in value, the fund’s share price will increase at the same rate as the enhanced returns sought by the fund, which is designed for an entire target outcome period. Trading flexible exchange options involves risks different from, or possibly greater than, the risks associated with investing directly in securities, such as less liquidity and correlation and valuation risks. A fund may experience substantial downside from specific flexible exchange option positions and certain positions may expire worthless.
Derivatives Risk. To the extent a fund uses derivative instruments such as futures contracts, options contracts and swaps, the fund may experience losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified
Page 34

Additional Information (Continued)
First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
by certain features of the derivative. These risks are heightened when a fund’s portfolio managers use derivatives to enhance the fund’s return or as a substitute for a position or security, rather than solely to hedge (or offset) the risk of a position or security held by the fund.
Equity Securities Risk. To the extent a fund invests in equity securities, the value of the fund’s shares will fluctuate with changes in the value of the equity securities. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant stock market, such as market volatility, or when political or economic events affecting the issuers occur. In addition, common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market.
ETF Risk. The shares of an ETF trade like common stock and represent an interest in a portfolio of securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities, although lack of liquidity in an ETF could result in it being more volatile and ETFs have management fees that increase their costs. Shares of an ETF trade on an exchange at market prices rather than net asset value, which may cause the shares to trade at a price greater than net asset value (premium) or less than net asset value (discount). In times of market stress, decisions by market makers to reduce or step away from their role of providing a market for an ETF’s shares, or decisions by an ETF’s authorized participants that they are unable or unwilling to proceed with creation and/or redemption orders of an ETF’s shares, could result in shares of the ETF trading at a discount to net asset value and in greater than normal intraday bid-ask spreads.
Fixed Income Securities Risk. To the extent a fund invests in fixed income securities, the fund will be subject to credit risk, income risk, interest rate risk, liquidity risk and prepayment risk. Income risk is the risk that income from a fund’s fixed income investments could decline during periods of falling interest rates. Interest rate risk is the risk that the value of a fund’s fixed income securities will decline because of rising interest rates. Liquidity risk is the risk that a security cannot be purchased or sold at the time desired, or cannot be purchased or sold without adversely affecting the price. Prepayment risk is the risk that the securities will be redeemed or prepaid by the issuer, resulting in lower interest payments received by the fund. In addition to these risks, high yield securities, or “junk” bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and the market for high yield securities is generally smaller and less liquid than that for investment grade securities.
Index or Model Constituent Risk. Certain funds may be a constituent of one or more indices or ETF models. As a result, such a fund may be included in one or more index-tracking exchange-traded funds or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving a fund, the size of the fund and the market volatility of the fund. Inclusion in an index could increase demand for the fund and removal from an index could result in outsized selling activity in a relatively short period of time. As a result, a fund’s net asset value could be negatively impacted and the fund’s market price may be significantly below its net asset value during certain periods. In addition, index rebalances may potentially result in increased trading activity in a fund’s shares.
Index Provider Risk. To the extent a fund seeks to track an index, it is subject to Index Provider Risk. There is no assurance that the Index Provider will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, the Index Provider may carry out an unscheduled rebalance or other modification of the Index constituents or weightings, which may increase the fund’s costs. The Index Provider does not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and it does not guarantee that the Index will be calculated in accordance with its stated methodology. Losses or costs associated with any Index Provider errors generally will be borne by the fund and its shareholders.
Investment Companies Risk. To the extent a fund invests in the securities of other investment vehicles, the fund will incur additional fees and expenses that would not be present in a direct investment in those investment vehicles. Furthermore, the fund’s investment performance and risks are directly related to the investment performance and risks of the investment vehicles in which the fund invests.
LIBOR Risk. To the extent a fund invests in floating or variable rate obligations that use the London Interbank Offered Rate (“LIBOR”) as a reference interest rate, it is subject to LIBOR Risk. The United Kingdom’s Financial Conduct Authority, which regulates LIBOR has ceased making LIBOR available as a reference rate over a phase-out period that began December 31, 2021. There is no assurance that any alternative reference rate, including the Secured Overnight Financing Rate (“SOFR”) will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. The unavailability or replacement of LIBOR may affect the value, liquidity or return on certain fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any potential effects of the transition away from LIBOR on the fund or on certain instruments in which the fund invests can be difficult to ascertain, and they may vary depending on a variety of factors, and they could result in losses to the fund.

Management Risk. To the extent that a fund is actively managed, it is subject to management risk. In managing an actively-managed fund’s investment portfolio, the fund’s portfolio managers will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that a fund will meet its investment objective.
Market Risk. Market risk is the risk that a particular security, or shares of a fund in general, may fall in value. Securities held by a fund, as well as shares of a fund itself, are subject to market fluctuations caused by factors such as general economic conditions, political events, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of a fund could decline in value or underperform other investments as a result of the risk of loss associated with these market fluctuations. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on a fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. In February 2022, Russia invaded Ukraine which has caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, and the United States. The hostilities and sanctions resulting from those hostilities could have a significant impact on certain fund investments as well as fund performance. The COVID-19 global pandemic and the ensuing policies enacted by governments and central banks have caused and may continue to cause significant volatility and uncertainty in global financial markets. While the U.S. has resumed “reasonably” normal business activity, many countries continue to impose lockdown measures. Additionally, there is no guarantee that vaccines will be effective against emerging variants of the disease. These events also adversely affect the prices and liquidity of a fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of a fund’s shares and result in increased market volatility. During any such events, a fund’s shares may trade at increased premiums or discounts to their net asset value and the bid/ask spread on a fund’s shares may widen.
Non-U.S. Securities Risk. To the extent a fund invests in non-U.S. securities, it is subject to additional risks not associated with securities of domestic issuers. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to: possible adverse political, social or economic developments; restrictions on foreign investment or exchange of securities; capital controls; lack of liquidity; currency exchange rates; excessive taxation; government seizure of assets; the imposition of sanctions by foreign governments; different legal or accounting standards; and less government supervision and regulation of exchanges in foreign countries. Investments in non-U.S. securities may involve higher costs than investments in U.S. securities, including higher transaction and custody costs, as well as additional taxes imposed by non-U.S. governments. These risks may be heightened for securities of companies located, or with significant operations, in emerging market countries.
Operational Risk. Each fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of a fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. Each fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect a fund’s ability to meet its investment objective. Although the funds and the funds’ investment advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.
Passive Investment Risk. To the extent a fund seeks to track an index, the fund will invest in the securities included in, or representative of, the index regardless of their investment merit. A fund generally will not attempt to take defensive positions in declining markets.
Preferred Securities Risk. Preferred securities combine some of the characteristics of both common stocks and bonds. Preferred securities are typically subordinated to bonds and other debt securities in a company’s capital structure in terms of priority to corporate income, subjecting them to greater credit risk than those debt securities. Generally, holders of preferred securities have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may obtain limited rights. In certain circumstances, an issuer of preferred securities may defer payment on the securities and, in some cases, redeem the securities prior to a specified date. Preferred securities may also be substantially less liquid than other securities, including common stock.
Valuation Risk. The valuation of certain securities may carry more risk than that of common stock. Uncertainties in the conditions of the financial markets, unreliable reference data, lack of transparency and inconsistency of valuation models and processes may lead to inaccurate asset pricing. A fund may hold investments in sizes smaller than institutionally sized round lot positions (sometimes referred to as odd lots). However, third-party pricing services generally provide evaluations on the basis of institutionally-sized round lots. If a fund sells certain of its investments in an odd lot transaction, the sale price may be less than the value at which such securities

have been held by the fund. Odd lots often trade at lower prices than institutional round lots. There is no assurance that the fund will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to the fund.

Advisory Agreements
Board Considerations Regarding Approval of Amendments to the Investment Management Agreements  
The Board of Trustees of First Trust Exchange-Traded Fund III (the “Trust”), including the Independent Trustees, unanimously approved the amendment (as applicable to a specific Fund, the “Amendment” and collectively, the “Amendments”) of the Investment Management Agreements (as applicable to a specific Fund, the “Agreement” and collectively, the “Agreements”) with First Trust Advisors L.P. (the “Advisor”) on behalf of the following two series of the Trust (each a “Fund” and collectively, the “Funds”):
First Trust California Municipal High Income ETF (FCAL)
First Trust New York Municipal High Income ETF (FMNY)
The Board approved the Amendment for each Fund at a meeting held on October 24, 2022.  As part of the review process, the Board reviewed information and had preliminary discussions with the Advisor regarding the proposed Amendments at meetings held on April 18, 2022, June 12–13, 2022 and September 18–19, 2022.  Following those preliminary discussions, the Board requested and received information from the Advisor regarding the proposed Amendments, and that information was considered at an executive session of the Independent Trustees and their counsel held prior to the October 24, 2022 meeting, as well as at the October meeting.
In reviewing the Amendment for each Fund, the Board considered that the purpose of the Amendments is to modify the unitary fee rate for each Fund under the applicable Agreement by introducing a breakpoint schedule pursuant to which the unitary fee rate paid by each Fund to the Advisor will be reduced as assets of such Fund meet certain thresholds.  The Board noted the Advisor’s representations that the quality and quantity of the services provided to each Fund by the Advisor under the applicable Agreement will not be reduced or modified as a result of the applicable Amendment, and that the obligations of the Advisor under each Agreement will remain the same in all respects.
The Board noted that it, including the Independent Trustees, last approved the continuation of the applicable Agreement for each Fund for a one-year period ending June 30, 2023 at a meeting held on June 12–13, 2022.  The Board noted that in connection with such approval it had determined for each Fund, based upon the information provided, that the terms of the applicable Agreement were fair and reasonable and that the continuation of the applicable Agreement was in the best interests of the Fund in light of the nature, extent and quality of the services provided and such other matters as the Board considered to be relevant in the exercise of its business judgment.
The Board noted that the Advisor had previously agreed to waive a portion of its unitary fee for each Fund and that the modified unitary fee rate schedule for each Fund under the applicable Amendment would not be implemented until the expiration of the Fund’s contractual fee waiver.  The Board considered that the effective unitary fee rate paid by each Fund under the applicable Agreement after taking into account the contractual fee waiver is less than the effective unitary fee rate that the Fund would pay pursuant to the modified unitary fee rate schedule under the applicable Amendment.
Based on all of the information considered, the Board, including the Independent Trustees, unanimously determined that the terms of the Amendments are fair and reasonable and that the Amendments are in the best interests of each Fund.

Shareholder Letter
First Trust Municipal High Income ETF (FMHI)
Semi-Annual Letter from the Chairman and CEO
January 31, 2023
Dear Shareholders,
First Trust is pleased to provide you with the semi-annual report for the First Trust Municipal High Income ETF (the “Fund”), which contains detailed information about the Fund for the six-month period ended January 31, 2023.
Given recent inflation data, the Federal Reserve’s (the “Fed”) monetary policy remains front and center in most discussions regarding the outlook of the U.S. economy. Annual revisions to the Consumer Price Index released on February 10, 2023, showed that prices climbed at a 3.3% annual rate in the last three months of 2022, not the 1.8% rate reported four weeks prior, according to Brian Wesbury, Chief Economist at First Trust. Additionally, “core” inflation, which excludes volatile food and energy prices, was also revised upwards from 3.1% to 4.3% over the period. Furthermore, January’s 2023 jobs data came in better than expected, with non-farm payroll employment rising by 517,000. It is precisely this situation: stubbornly high inflation, strong jobs growth and increasing interest rates, which has many pundits debating whether the typical U.S. consumer can remain healthy enough to help ward off an economic recession.
As many investors know, the consumer is an essential driver of economic growth in the U.S. On average, over the 15-year period ended October 1, 2022, consumer spending accounted for 67.8% of the U.S. gross domestic product (“GDP”). Crucially, recent data regarding consumer health has been mixed, in my opinion. On one hand, the Commerce Department reported that in December 2022, the U.S. savings rate rose to its highest level in seven months, coming in at 3.4%. On the other hand, while December’s savings rate was a welcome reversal from the declines suffered throughout 2021 and 2022, it could indicate that consumers are beginning to pull back on discretionary spending amidst a cloudier economic outlook, according to Bloomberg. Recent data shows that the average interest rate on U.S. credit cards rose to 19.07% in the fourth quarter of 2022, its highest level in over 50 years. Additionally, U.S. credit card debt reached a record $930.6 billion in the fourth quarter, jumping 18.5% year-over-year. Even so, debt service payments accounted for just 9.75% of disposable personal income in the third quarter of 2022. This figure is higher than its historic low of 8.33% set in 2021 but is also well below its peak of 13.17% set in 2007. In my view, it is worth keeping an eye on debt service payments. If higher payments lead to a decline in discretionary spending, it could negatively impact GDP.
I would like to take a moment to remind you that even though nearly three years have passed since the World Health Organization initially declared the coronavirus outbreak a global pandemic, the economic impact of worldwide lockdowns and the subsequent governmental stimulus is still very real. China, for example, only recently dropped its requirement that incoming travelers must quarantine before entering the country. In addition, the global economy has yet to fully absorb the impact of the fiscal policies enacted to jump start consumer spending in 2020, in my view. As evidence of this, each of the countries that comprise the G-10 currently has a headline inflation rate that stands well above its stated target. Central banks likely have more work to do, in my opinion.
Thank you for giving First Trust the opportunity to play a role in your financial future. We value our relationship with you and will report on the Fund again in six months.
Sincerely,
James A. Bowen
Chairman of the Board of Trustees
Chief Executive Officer of First Trust Advisors L.P.

Fund Performance Overview (Unaudited)
First Trust Municipal High Income ETF (FMHI)
The First Trust Municipal High Income ETF’s (the “Fund”) primary investment objective is to provide federally tax-exempt income, and its secondary objective is long-term capital appreciation.  Under normal market conditions, the Fund seeks to achieve its investment objectives by investing at least 80% of its net assets (including investment borrowings) in municipal debt securities that pay interest that is exempt from regular federal income taxes (“Municipal Securities”). Under normal market conditions, the Fund invests at least 50% of its net assets in Municipal Securities that are, at the time of investment, rated below investment grade by at least one nationally recognized statistical rating organization rating such securities (or Municipal Securities that are unrated and determined by the Fund’s advisor to be of comparable quality), commonly referred to as “high yield” or “junk” bonds.  The Fund lists and principally trades its shares on The Nasdaq Stock Market LLC under the ticker symbol “FMHI.”

Total returns for the period since inception are calculated from the inception date of the Fund. “Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated. The total returns would have been lower if certain fees had not been waived by the Advisor.
The Fund’s per share net asset value (“NAV”) is the value of one share of the Fund and is computed by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of outstanding shares. The price used to calculate market return (“Market Price”) is determined by using the midpoint of the national best bid and offer price (“NBBO”) as of the time that the Fund’s NAV is calculated. Under SEC rules, the NBBO consists of the highest displayed buy and lowest sell prices among the various exchanges trading the Fund at the time the Fund’s NAV is calculated. Prior to January 1, 2019, the price used was the midpoint between the highest bid and the lowest offer on the stock exchange on which shares of the Fund were listed for trading as of the time that the Fund’s NAV was calculated. Since shares of the Fund did not trade in the secondary market until after its inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the secondary market trading price to calculate market returns. NAV and market returns assume that all distributions have been reinvested in the Fund at NAV and Market Price, respectively.
An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the indices that make up the Blended Benchmark do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The total returns presented reflect the reinvestment of dividends on securities in the indices. The returns presented do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future performance.

(1) The Blended Benchmark consists of the following two indexes: 50% of the Bloomberg High Yield 10-Year Municipal Index (8-12 years) which is comprised of bonds with a final maturity between 8 and 12 years that are part of the Bloomberg Municipal Bond High Yield Index; and 50% of the Bloomberg Revenue 10-Year Municipal Index (8-12 years), which is comprised of revenue bonds that have a final maturity between 8 and 12 years that are part of the Bloomberg Municipal Bond Index. Indexes do not charge management fees or brokerage expenses, and no such fees or expenses were deducted from the index performance shown. Indexes are unmanaged and an investor cannot invest directly in an index. The Blended Benchmark returns are calculated by using the monthly return of the two indices during each period shown above. At the beginning of each month the two indices are rebalanced to a 50-50 ratio to account for divergence from that ratio that occurred during the course of each month. The monthly returns are then compounded for each period shown above, giving the performance for the Blended Benchmark for each period shown above.

(2) The credit quality and ratings information presented above reflect the ratings assigned by one or more nationally recognized statistical rating organizations (NRSROs), including S&P Global Ratings, Moody’s Investors Service, Inc., Fitch Ratings or a comparably rated NRSRO. For situations in which a security is rated by more than one NRSRO and the ratings are not equivalent, the highest rating is used.  Sub-investment grade ratings are those rated BB+/Ba1 or lower. Investment grade ratings are those rated BBB-/Baa3 or higher. The credit ratings shown relate to the creditworthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. Credit ratings are subject to change.

Fund Performance Overview (Unaudited) (Continued)
First Trust Municipal High Income ETF (FMHI) (Continued)

Performance figures assume reinvestment of all distributions and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. The Fund’s past performance does not predict future performance.

Performance in municipal bond investment strategies can be impacted from the benefits of purchasing odd lot positions. The impact of these investments can be particularly meaningful when funds have limited assets under management and may not be a sustainable source of performance as a fund grows in size.
Frequency Distribution of Discounts and Premiums
Information showing the number of days the market price of the Fund’s shares was greater (at a premium) and less (at a discount) than the Fund’s net asset value for the most recently completed year, and the most recently completed calendar quarters since that year (or life of the Fund, if shorter), is available at https://www.ftportfolios.com/Retail/etf/home.aspx.

Understanding Your Fund Expenses
January 31, 2023 (Unaudited)
As a shareholder of the First Trust Municipal High Income ETF (the “Fund”), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs of investing in the Fund and to compare these costs with the ongoing costs of investing in other funds.
The Example is based on an investment of $1,000 invested at the beginning of the period and held through the six-month period ended January 31, 2023.
Actual Expenses
The first line in the following table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During the Six-Month Period” to estimate the expenses you paid on your account during this six-month period.
Hypothetical Example for Comparison Purposes
The second line in the following table provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.
Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs such as brokerage commissions. Therefore, the second line in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

(a) Variable Rate Demand bond. Interest rate is reset periodically by the agent based on current market conditions.
(b) This security, sold within the terms of a private placement memorandum, is exempt from registration upon resale under Rule 144A of the Securities Act of 1933, as amended (the “1933 Act”), and may be resold in transactions exempt from registration, normally to qualified institutional buyers. Pursuant to procedures adopted by the Trust’s Board of Trustees, this security has been determined to be liquid by First Trust Advisors L.P. (the “Advisor”). Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security specific factors and assumptions, which require subjective judgment. At January 31, 2023, securities noted as such amounted to $91,619,824 or 28.7% of net assets.
(c) This issuer is in default and interest is not being accrued by the Fund.
(d) Pursuant to procedures adopted by the Trust’s Board of Trustees, this security has been determined to be illiquid by the Advisor.
(e) When-issued security. The interest rate shown reflects the rate in effect at January 31, 2023. Interest will begin accruing on the security’s first settlement date.
(f) Zero coupon bond.
(g) This security, sold within the terms of a private placement memorandum, is exempt from registration upon resale under Rule 144A of the 1933 Act, and may be resold in transactions exempt from registration, normally to qualified institutional buyers (see Note 2C - Restricted Securities in the Notes to Financial Statements).

First Trust Municipal High Income ETF (FMHI)
January 31, 2023 (Unaudited)
1. Organization
First Trust Exchange-Traded Fund III (the “Trust”) is an open-end management investment company organized as a Massachusetts business trust on January 9, 2008, and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended (the “1940 Act”).
The Trust currently consists of seventeen funds that are offering shares. This report covers the First Trust Municipal High Income ETF (the “Fund”), a diversified series of the Trust, which trades under the ticker “FMHI” on The Nasdaq Stock Market LLC (“Nasdaq”). The Fund represents a separate series of beneficial interest in the Trust. Unlike conventional mutual funds, the Fund issues and redeems shares on a continuous basis, at net asset value (“NAV”), only in large blocks of shares known as “Creation Units.”
The primary investment objective of the Fund is to provide federally tax-exempt income, and its secondary objective is long-term capital appreciation. Under normal market conditions, the Fund seeks to achieve its investment objectives by investing at least 80% of its net assets (including investment borrowings) in municipal debt securities that pay interest that is exempt from regular federal income taxes. There can be no assurance that the Fund will achieve its investment objectives. The Fund may not be appropriate for all investors.
2. Significant Accounting Policies
The Fund is considered an investment company and follows accounting and reporting guidance under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946, “Financial Services-Investment Companies.” The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of the financial statements. The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.
A. Portfolio Valuation
The Fund’s NAV is determined daily as of the close of regular trading on the New York Stock Exchange (“NYSE”), normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. Domestic debt securities are priced using data reflecting the earlier closing of the principal markets for those securities. The Fund’s NAV is calculated by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of shares outstanding.
The Fund’s investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent readily available market quotations such as last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Pricing Committee of the Fund’s investment advisor, First Trust Advisors L.P. (“First Trust” or the “Advisor”), in accordance with valuation procedures approved by the Trust’s Board of Trustees, and in accordance with provisions of the 1940 Act and rules thereunder. Investments valued by the Advisor’s Pricing Committee, if any, are footnoted as such in the footnotes to the Portfolio of Investments. The Fund’s investments are valued as follows:
Municipal securities and other debt securities are fair valued on the basis of fair valuations provided by a third-party pricing service approved by the Advisor’s Pricing Committee, which may use the following valuation inputs when available:
1) benchmark yields;
2) reported trades;
3) broker/dealer quotes;
4) issuer spreads;
5) benchmark securities;
6) bids and offers; and
7) reference data including market research publications.
Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but a Fund may hold or transact in such securities in smaller, odd lot sizes. Odd lots may trade at lower prices than institutional round lots.
Exchange-traded futures contracts are valued at the closing price in the market where such contracts are principally traded. If no closing price is available, exchange-traded futures contracts are valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price.

Notes to Financial Statements (Continued)
First Trust Municipal High Income ETF (FMHI)
January 31, 2023 (Unaudited)
Fixed income and other debt securities having a remaining maturity of sixty days or less when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discounts (amortized cost), provided the Advisor’s Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of the determination. Factors that may be considered in determining the appropriateness of the use of amortized cost include, but are not limited to, the following:
1) the credit conditions in the relevant market and changes thereto;
2) the liquidity conditions in the relevant market and changes thereto;
3) the interest rate conditions in the relevant market and changes thereto (such as significant changes in interest rates);
4) issuer-specific conditions (such as significant credit deterioration); and
5) any other market-based data the Advisor’s Pricing Committee considers relevant. In this regard, the Advisor’s Pricing Committee may use last-obtained market-based data to assist it when valuing portfolio securities using amortized cost.
Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Advisor’s Pricing Committee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended (the “1933 Act”)) for which a third-party pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of the Fund’s NAV or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the third-party pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchanges. A variety of factors may be considered in determining the fair value of such securities, including, but not limited to, the following:
1) the fundamental business data relating to the issuer;
2) an evaluation of the forces which influence the market in which these securities are purchased and sold;
3) the type, size and cost of the security;
4) the financial statements of the issuer;
5) the credit quality and cash flow of the issuer, based on the Advisor’s or external analysis;
6) the information as to any transactions in or offers for the security;
7) the price and extent of public trading in similar securities (or equity securities) of the issuer/borrower, or comparable companies;
8) the coupon payments;
9) the quality, value and salability of collateral, if any, securing the security; and
10) other relevant factors.
The Fund is subject to fair value accounting standards that define fair value, establish the framework for measuring fair value and provide a three-level hierarchy for fair valuation based upon the inputs to the valuation as of the measurement date. The three levels of the fair value hierarchy are as follows:
Level 1 – Level 1 inputs are quoted prices in active markets for identical investments. An active market is a market in which transactions for the investment occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:
o Quoted prices for similar investments in active markets.
o Quoted prices for identical or similar investments in markets that are non-active. A non-active market is a market where there are few transactions for the investment, the prices are not current, or price quotations vary substantially either over time or among market makers, or in which little information is released publicly.
o Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).
o Inputs that are derived principally from or corroborated by observable market data by correlation or other means.
Level 3 – Level 3 inputs are unobservable inputs. Unobservable inputs may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value the Fund’s investments as of January 31, 2023, is included with the Fund’s Portfolio of Investments.
B. Securities Transactions and Investment Income
Securities transactions are recorded as of the trade date. Realized gains and losses from securities transactions are recorded on the identified cost basis. Interest income is recorded daily on the accrual basis. Amortization of premiums and accretion of discounts are recorded using the effective interest method.
Securities purchased or sold on a when-issued or delayed-delivery basis may have extended settlement periods. The value of the security so purchased is subject to market fluctuations during this period. The Fund maintains liquid assets with a current value at least equal to the amount of its when-issued or delayed-delivery securities. At January 31, 2023, the Fund held $4,449,575 of when-issued or delayed-delivery securities.
C. Restricted Securities
The Fund invests in restricted securities, which are securities that may not be offered for public sale without first being registered under the 1933 Act. Prior to registration, restricted securities may only be resold in transactions exempt from registration under Rule 144A under the 1933 Act, normally to qualified institutional buyers. As of January 31, 2023, the Fund held restricted securities as shown in the following table that the Advisor has deemed illiquid pursuant to procedures adopted by the Trust’s Board of Trustees. Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security-specific factors and assumptions, which require subjective judgment. The Fund does not have the right to demand that such securities be registered. These securities are valued according to the valuation procedures as stated in the Portfolio Valuation note (Note 2A) and are not expressed as a discount to the carrying value of a comparable unrestricted security. There are no unrestricted securities with the same maturity dates and yields for these issuers.

        $351,395   $348,970   0.11%
D. Futures Contracts
The Fund may purchase or sell (i.e., is long or short) exchange-listed futures contracts to hedge against changes in interest rates (interest rate risk). Futures contracts are agreements between the Fund and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and at a specified date. Depending on the terms of the contract, futures contracts are settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date. Open futures contracts can also be closed out prior to settlement by entering into an offsetting transaction in a matching futures contract. If the Fund is not able to enter into an offsetting transaction, the Fund will continue to be required to maintain margin deposits on the futures contract. When the contract is closed or expires, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed or expired. This gain or loss is included in “Net realized gain (loss) on futures contracts” on the Statement of Operations.
Upon entering into a futures contract, the Fund must deposit funds, called margin, with its custodian in the name of the clearing broker equal to a specified percentage of the current value of the contract. Open futures contracts are marked to market daily with the change in value recognized as a component of “Net change in unrealized appreciation (depreciation) on futures contracts” on the Statement of Operations. This daily fluctuation in the value of the contracts is also known as variation margin and is included in “Variation margin” payable or receivable on the Statement of Assets and Liabilities.
If market conditions change unexpectedly, the Fund may not achieve the anticipated benefits of the futures contract and may realize a loss. The use of futures contracts involves the risk of imperfect correlation in movements in the price of the futures contracts, interest rates and the underlying instruments.

Restricted cash segregated as collateral for futures contracts in the amount of $327,250 is shown as “Cash segregated as collateral for open futures contracts” on the Statement of Assets and Liabilities.
E. Dividends and Distributions to Shareholders
Dividends from net investment income, if any, are declared and paid monthly by the Fund, or as the Board of Trustees may determine from time to time. Distributions of net realized capital gains earned by the Fund, if any, are distributed at least annually. The Fund may also designate a portion of the amount paid to redeeming shareholders as a distribution for tax purposes.
Distributions from net investment income and realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These permanent differences are primarily due to the varying treatment of income and gain/loss on portfolio securities held by the Fund and have no impact on net assets or NAV per share. Temporary differences, which arise from recognizing certain items of income, expense and gain/loss in different periods for financial statement and tax purposes, will reverse at some time in the future.
The tax character of distributions paid by the Fund during the fiscal year ended July 31, 2022, was as follows:
Distributions paid from:  
Ordinary income

$19,097
Capital gains

Tax-exempt income

9,541,080
Return of capital

505,451
As of July 31, 2022, the components of distributable earnings on a tax basis were as follows:
Undistributed ordinary income

$
Accumulated capital and other gain (loss)

(20,197,363)
Net unrealized appreciation (depreciation)

(13,289,674)
F. Income Taxes
The Fund intends to continue to qualify as a regulated investment company by complying with the requirements under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), which includes distributing substantially all of its net investment income and net realized gains to shareholders. Accordingly, no provision has been made for federal and state income taxes. However, due to the timing and amount of distributions, the Fund may be subject to an excise tax of 4% of the amount by which approximately 98% of the Fund’s taxable income exceeds the distributions from such taxable income for the calendar year.
In addition, the Fund intends to invest in such municipal securities to allow it to pay shareholders “exempt dividends” as defined in the Code.
The Fund is subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. Taxable years ended 2019, 2020, 2021 and 2022 remain open to federal and state audit. As of January 31, 2023, management has evaluated the application of these standards to the Fund, and has determined that no provision for income tax is required in the Fund’s financial statements for uncertain tax positions.
The Fund intends to utilize provisions of the federal income tax laws, which allow it to carry a realized capital loss forward indefinitely following the year of the loss and offset such loss against any future realized capital gains. The Fund is subject to certain limitations under U.S. tax rules on the use of capital loss carryforwards and net unrealized built-in losses. These limitations apply when there has been a 50% change in ownership. At July 31, 2022, for federal income tax purposes, the Fund had $20,197,363 of capital loss carryforwards available, to the extent provided by regulations, to offset future capital gains.
Certain losses realized during the current fiscal year may be deferred and treated as occurring on the first day of the following fiscal year for federal income tax purposes. For the fiscal year ended July 31, 2022, the Fund had no net ordinary losses.

G. Expenses
Expenses, other than the investment advisory fee and other excluded expenses, are paid by the Advisor (See Note 3).
3. Investment Advisory Fee, Affiliated Transactions and Other Fee Arrangements
First Trust, the investment advisor to the Fund, is a limited partnership with one limited partner, Grace Partners of DuPage L.P., and one general partner, The Charger Corporation. The Charger Corporation is an Illinois corporation controlled by James A. Bowen, Chief Executive Officer of First Trust. First Trust is responsible for the selection and ongoing monitoring of the securities in the Fund’s portfolio, managing the Fund’s business affairs and providing certain administrative services necessary for the management of the Fund.
Pursuant to the Investment Management Agreement between the Trust and the Advisor, First Trust manages the investment of the Fund’s assets and is responsible for the Fund’s expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, acquired fund fees and expenses, if any, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses. Effective November 1, 2022, the annual unitary management fee payable by the Fund to First Trust for these services will be reduced at certain levels of the Fund’s net assets (“breakpoints”) and calculated pursuant to the schedule below.
Breakpoints  
Fund net assets up to and including $2.5 billion 0.7000%
Fund net assets greater than $2.5 billion up to and including $5 billion 0.6825%
Fund net assets greater than $5 billion up to and including $7.5 billion 0.6650%
Fund net assets greater than $7.5 billion up to and including $10 billion 0.6475%
Fund net assets greater than $10 billion 0.6300%
Prior to November 1, 2022, the Fund paid First Trust an annual unitary management fee equal to 0.70% of its average daily net assets. First Trust also provides fund reporting services to the Fund for a flat annual fee in the amount of $9,250, which is covered under the annual unitary management fee.
The Trust’s Board of Trustees and the Advisor have entered into a Fee Waiver Agreement for the Fund pursuant to which the Advisor contractually agreed to waive management fees of 0.15% of average daily net assets until November 30, 2022. First Trust does not have the right to recover the fees waived. The Fee Waiver Agreement terminated on November 30, 2022. During the six months ended January 31, 2023, the Advisor waived fees of $155,286.
The Trust has multiple service agreements with Brown Brothers Harriman & Co. (“BBH”). Under the service agreements, BBH performs custodial, fund accounting, certain administrative services, and transfer agency services for the Fund. As custodian, BBH is responsible for custody of the Fund’s assets. As fund accountant and administrator, BBH is responsible for maintaining the books and records of the Fund’s securities and cash. As transfer agent, BBH is responsible for maintaining shareholder records for the Fund.
Each Trustee who is not an officer or employee of First Trust, any sub-advisor or any of their affiliates (“Independent Trustees”) is paid a fixed annual retainer that is allocated equally among each fund in the First Trust Fund Complex. Each Independent Trustee is also paid an annual per fund fee that varies based on whether the fund is a closed-end or other actively managed fund, a target outcome fund or an index fund.
Additionally, the Lead Independent Trustee and the Chairs of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Independent Trustees are reimbursed for travel and out-of-pocket expenses in
Page 28

connection with all meetings. The Lead Independent Trustee and Committee Chairs rotate every three years. The officers and “Interested” Trustee receive no compensation from the Trust for acting in such capacities.
4. Purchases and Sales of Securities
For the six months ended January 31, 2023, the cost of purchases and proceeds from sales of investments, excluding short term investments and in-kind transactions, were $154,114,240 and $164,220,781, respectively.
For the six months ended January 31, 2023, the Fund had no in-kind transactions.
5. Derivative Transactions

The Fund does not have the right to offset financial assets and liabilities related to futures contracts on the Statement of Assets and Liabilities.
6. Creations, Redemptions and Transaction Fees
The Fund generally issues and redeems its shares in primary market transactions through a creation and redemption mechanism and does not sell or redeem individual shares. Instead, financial entities known as “Authorized Participants” have contractual arrangements with the Fund or one of the Fund’s service providers to purchase and redeem Fund shares directly with the Fund in large blocks of shares known as “Creation Units.” Prior to the start of trading on every business day, the Fund publishes through the National Securities Clearing Corporation (“NSCC”) the “basket” of securities, cash or other assets that it will accept in exchange for a Creation Unit of the Fund’s shares. An Authorized Participant that wishes to effectuate a creation of the Fund’s shares deposits with the Fund the “basket” of securities, cash or other assets identified by the Fund that day, and then receives the Creation Unit of the Fund’s shares in return for those assets. After purchasing a Creation Unit, the Authorized Participant may continue to hold the Fund’s shares or sell them in the secondary market. The redemption process is the reverse of the purchase process: the Authorized Participant redeems a Creation Unit of the Fund’s shares for a basket of securities, cash or other assets. The combination of the creation and redemption process with secondary market trading in the Fund’s shares and underlying securities provides arbitrage opportunities that are designed to help keep the market price of the Fund’s shares at or close to the NAV per share of the Fund.
The Fund imposes fees in connection with the purchase of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price for each Creation Unit will equal the daily NAV per share of the Fund times the number of shares in a Creation Unit, plus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees,
Page 29

Notes to Financial Statements (Continued)
First Trust Municipal High Income ETF (FMHI)
January 31, 2023 (Unaudited)
stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the creation basket.
The Fund also imposes fees in connection with the redemption of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price received for each Creation Unit will equal the daily NAV per share of the Fund times the number of shares in a Creation Unit, minus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the redemption basket. Investors who use the services of a broker or other such intermediary in addition to an Authorized Participant to effect a redemption of a Creation Unit may also be assessed an amount to cover the cost of such services. The redemption fee charged by the Fund will comply with Rule 22c-2 of the 1940 Act which limits redemption fees to no more than 2% of the value of the shares redeemed.
7. Distribution Plan
The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. (“FTP”), the distributor of the Fund, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or to provide investor services. FTP may also use this amount to compensate securities dealers or other persons that are Authorized Participants for providing distribution assistance, including broker-dealer and shareholder support and educational and promotional services.
No 12b-1 fees are currently paid by the Fund, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before November 30, 2023.
8. Borrowings
The Trust, on behalf of the Fund, along with First Trust Series Fund and First Trust Exchange-Traded Fund IV have a $305 million Credit Agreement with The Bank of Nova Scotia (“Scotia”) as administrative agent for a group of lenders. Prior to October 30, 2022, the commitment amount was $280 million. Scotia charges a commitment fee of 0.25% of the daily amount of the excess of the commitment amount over the outstanding principal balance of the loans and an agency fee. First Trust allocates the commitment fee and agency fee amongst the funds that have access to the credit line. To the extent that the Fund accesses the credit line, there would also be an interest fee charged. The Fund did not have any borrowings outstanding during the six months ended January 31, 2023.
9. Indemnification
The Trust, on behalf of the Fund, has a variety of indemnification obligations under contracts with its service providers. The Trust’s maximum exposure under these arrangements is unknown. However, the Trust has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.
10. Subsequent Events
Management has evaluated the impact of all subsequent events to the Fund through the date the financial statements were issued and has determined that there was the following subsequent event:
Effective March 1, 2023, the credit agreement with Scotia was amended, and the maximum commitment amount changed from $305,000,000 to $550,000,000.

Risk Considerations
Risks are inherent in all investing. Certain general risks that may be applicable to a Fund are identified below, but not all of the material risks relevant to each Fund are included in this report and not all of the risks below apply to each Fund. The material risks of investing in each Fund are spelled out in its prospectus, statement of additional information and other regulatory filings. Before investing, you should consider each Fund’s investment objective, risks, charges and expenses, and read each Fund’s prospectus and statement of additional information carefully. You can download each Fund’s prospectus at www.ftportfolios.com or contact First Trust Portfolios L.P. at (800) 621-1675 to request a prospectus, which contains this and other information about each Fund.
Concentration Risk. To the extent that a fund is able to invest a significant percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the fund’s investments more than if the fund were more broadly diversified. A fund that tracks an index will be concentrated to the extent the fund’s corresponding index is concentrated. A concentration makes a fund more susceptible to any single occurrence and may subject the fund to greater market risk than a fund that is more broadly diversified.
Credit Risk. Credit risk is the risk that an issuer of a security will be unable or unwilling to make dividend, interest and/or principal payments when due and the related risk that the value of a security may decline because of concerns about the issuer’s ability to make such payments.
Cyber Security Risk. The funds are susceptible to potential operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause a fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause a fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. In addition, cyber security breaches of a fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, or issuers in which the fund invests, can also subject a fund to many of the same risks associated with direct cyber security breaches.
Defined Outcome Funds Risk. To the extent a fund’s investment strategy is designed to deliver returns tied to the price performance of an underlying ETF, an investor may not realize the returns the fund seeks to achieve if that investor does not hold shares for the entire target outcome period. In the event an investor purchases shares after the first day of the target outcome period or sells shares prior to the end of the target outcome period, the buffer that the fund seeks to provide against a decline in the value of the underlying ETF may not be available, the enhanced returns that the fund seeks to provide (if any) may not be available and the investor may not participate in a gain in the value of the underlying ETF up to the cap for the investor’s investment period. Additionally, the fund will not participate in gains of the underlying ETF above the cap and a shareholder may lose their entire investment. If the fund seeks enhanced returns, there are certain time periods when the value of the fund may fall faster than the value of the underlying ETF, and it is very unlikely that, on any given day during which the underlying ETF share price increases in value, the fund’s share price will increase at the same rate as the enhanced returns sought by the fund, which is designed for an entire target outcome period. Trading flexible exchange options involves risks different from, or possibly greater than, the risks associated with investing directly in securities, such as less liquidity and correlation and valuation risks. A fund may experience substantial downside from specific flexible exchange option positions and certain positions may expire worthless.
Derivatives Risk. To the extent a fund uses derivative instruments such as futures contracts, options contracts and swaps, the fund may experience losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified

by certain features of the derivative. These risks are heightened when a fund’s portfolio managers use derivatives to enhance the fund’s return or as a substitute for a position or security, rather than solely to hedge (or offset) the risk of a position or security held by the fund.
Equity Securities Risk. To the extent a fund invests in equity securities, the value of the fund’s shares will fluctuate with changes in the value of the equity securities. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant stock market, such as market volatility, or when political or economic events affecting the issuers occur. In addition, common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market.
ETF Risk. The shares of an ETF trade like common stock and represent an interest in a portfolio of securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities, although lack of liquidity in an ETF could result in it being more volatile and ETFs have management fees that increase their costs. Shares of an ETF trade on an exchange at market prices rather than net asset value, which may cause the shares to trade at a price greater than net asset value (premium) or less than net asset value (discount). In times of market stress, decisions by market makers to reduce or step away from their role of providing a market for an ETF’s shares, or decisions by an ETF’s authorized participants that they are unable or unwilling to proceed with creation and/or redemption orders of an ETF’s shares, could result in shares of the ETF trading at a discount to net asset value and in greater than normal intraday bid-ask spreads.
Fixed Income Securities Risk. To the extent a fund invests in fixed income securities, the fund will be subject to credit risk, income risk, interest rate risk, liquidity risk and prepayment risk. Income risk is the risk that income from a fund’s fixed income investments could decline during periods of falling interest rates. Interest rate risk is the risk that the value of a fund’s fixed income securities will decline because of rising interest rates. Liquidity risk is the risk that a security cannot be purchased or sold at the time desired, or cannot be purchased or sold without adversely affecting the price. Prepayment risk is the risk that the securities will be redeemed or prepaid by the issuer, resulting in lower interest payments received by the fund. In addition to these risks, high yield securities, or “junk” bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and the market for high yield securities is generally smaller and less liquid than that for investment grade securities.
Index or Model Constituent Risk. Certain funds may be a constituent of one or more indices or ETF models. As a result, such a fund may be included in one or more index-tracking exchange-traded funds or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving a fund, the size of the fund and the market volatility of the fund. Inclusion in an index could increase demand for the fund and removal from an index could result in outsized selling activity in a relatively short period of time. As a result, a fund’s net asset value could be negatively impacted and the fund’s market price may be significantly below its net asset value during certain periods. In addition, index rebalances may potentially result in increased trading activity in a fund’s shares.
Index Provider Risk. To the extent a fund seeks to track an index, it is subject to Index Provider Risk. There is no assurance that the Index Provider will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, the Index Provider may carry out an unscheduled rebalance or other modification of the Index constituents or weightings, which may increase the fund’s costs. The Index Provider does not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and it does not guarantee that the Index will be calculated in accordance with its stated methodology. Losses or costs associated with any Index Provider errors generally will be borne by the fund and its shareholders.
Investment Companies Risk. To the extent a fund invests in the securities of other investment vehicles, the fund will incur additional fees and expenses that would not be present in a direct investment in those investment vehicles. Furthermore, the fund’s investment performance and risks are directly related to the investment performance and risks of the investment vehicles in which the fund invests.
LIBOR Risk. To the extent a fund invests in floating or variable rate obligations that use the London Interbank Offered Rate (“LIBOR”) as a reference interest rate, it is subject to LIBOR Risk. The United Kingdom’s Financial Conduct Authority, which regulates LIBOR has ceased making LIBOR available as a reference rate over a phase-out period that began December 31, 2021. There is no assurance that any alternative reference rate, including the Secured Overnight Financing Rate (“SOFR”) will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. The unavailability or replacement of LIBOR may affect the value, liquidity or return on certain fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any potential effects of the transition away from LIBOR on the fund or on certain instruments in which the fund invests can be difficult to ascertain, and they may vary depending on a variety of factors, and they could result in losses to the fund.

Management Risk. To the extent that a fund is actively managed, it is subject to management risk. In managing an actively-managed fund’s investment portfolio, the fund’s portfolio managers will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that a fund will meet its investment objective.
Market Risk. Market risk is the risk that a particular security, or shares of a fund in general, may fall in value. Securities held by a fund, as well as shares of a fund itself, are subject to market fluctuations caused by factors such as general economic conditions, political events, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of a fund could decline in value or underperform other investments as a result of the risk of loss associated with these market fluctuations. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on a fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. In February 2022, Russia invaded Ukraine which has caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, and the United States. The hostilities and sanctions resulting from those hostilities could have a significant impact on certain fund investments as well as fund performance. The COVID-19 global pandemic and the ensuing policies enacted by governments and central banks have caused and may continue to cause significant volatility and uncertainty in global financial markets. While the U.S. has resumed “reasonably” normal business activity, many countries continue to impose lockdown measures. Additionally, there is no guarantee that vaccines will be effective against emerging variants of the disease. These events also adversely affect the prices and liquidity of a fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of a fund’s shares and result in increased market volatility. During any such events, a fund’s shares may trade at increased premiums or discounts to their net asset value and the bid/ask spread on a fund’s shares may widen.
Non-U.S. Securities Risk. To the extent a fund invests in non-U.S. securities, it is subject to additional risks not associated with securities of domestic issuers. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to: possible adverse political, social or economic developments; restrictions on foreign investment or exchange of securities; capital controls; lack of liquidity; currency exchange rates; excessive taxation; government seizure of assets; the imposition of sanctions by foreign governments; different legal or accounting standards; and less government supervision and regulation of exchanges in foreign countries. Investments in non-U.S. securities may involve higher costs than investments in U.S. securities, including higher transaction and custody costs, as well as additional taxes imposed by non-U.S. governments. These risks may be heightened for securities of companies located, or with significant operations, in emerging market countries.
Operational Risk. Each fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of a fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. Each fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect a fund’s ability to meet its investment objective. Although the funds and the funds’ investment advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.
Passive Investment Risk. To the extent a fund seeks to track an index, the fund will invest in the securities included in, or representative of, the index regardless of their investment merit. A fund generally will not attempt to take defensive positions in declining markets.
Preferred Securities Risk. Preferred securities combine some of the characteristics of both common stocks and bonds. Preferred securities are typically subordinated to bonds and other debt securities in a company’s capital structure in terms of priority to corporate income, subjecting them to greater credit risk than those debt securities. Generally, holders of preferred securities have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may obtain limited rights. In certain circumstances, an issuer of preferred securities may defer payment on the securities and, in some cases, redeem the securities prior to a specified date. Preferred securities may also be substantially less liquid than other securities, including common stock.
Valuation Risk. The valuation of certain securities may carry more risk than that of common stock. Uncertainties in the conditions of the financial markets, unreliable reference data, lack of transparency and inconsistency of valuation models and processes may lead to inaccurate asset pricing. A fund may hold investments in sizes smaller than institutionally sized round lot positions (sometimes referred to as odd lots). However, third-party pricing services generally provide evaluations on the basis of institutionally-sized round lots. If a fund sells certain of its investments in an odd lot transaction, the sale price may be less than the value at which such securities
Page 33

have been held by the fund. Odd lots often trade at lower prices than institutional round lots. There is no assurance that the fund will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to the fund.

Advisory Agreement
Board Considerations Regarding Approval of Amendment to the Investment Management Agreement
The Board of Trustees of First Trust Exchange-Traded Fund III (the “Trust”), including the Independent Trustees, unanimously approved the amendment (the “Amendment”) of the Investment Management Agreement (the “Agreement”) with First Trust Advisors L.P. (the “Advisor”) on behalf of the First Trust Municipal High Income ETF (the “Fund”).
The Board approved the Amendment at a meeting held on October 24, 2022. As part of the review process, the Board reviewed information and had preliminary discussions with the Advisor regarding the proposed Amendment at meetings held on April 18, 2022, June 12–13, 2022 and September 18–19, 2022. Following those preliminary discussions, the Board requested and received information from the Advisor regarding the proposed Amendment, and that information was considered at an executive session of the Independent Trustees and their counsel held prior to the October 24, 2022 meeting, as well as at the October meeting.
In reviewing the Amendment, the Board considered that the purpose of the Amendment is to modify the unitary fee rate for the Fund under the Agreement by introducing a breakpoint schedule pursuant to which the unitary fee rate paid by the Fund to the Advisor will be reduced as assets of the Fund meet certain thresholds. The Board noted the Advisor’s representations that the quality and quantity of the services provided to the Fund by the Advisor under the Agreement will not be reduced or modified as a result of the Amendment, and that the obligations of the Advisor under the Agreement will remain the same in all respects.
The Board noted that it, including the Independent Trustees, last approved the continuation of the Agreement for a one-year period ending June 30, 2023 at a meeting held on June 12–13, 2022. The Board noted that in connection with such approval it had determined, based upon the information provided, that the terms of the Agreement were fair and reasonable and that the continuation of the Agreement was in the best interests of the Fund in light of the nature, extent and quality of the services provided and such other matters as the Board considered to be relevant in the exercise of its business judgment.
The Board noted that the Advisor had previously agreed to waive a portion of its unitary fee for the Fund and that the modified unitary fee rate schedule for the Fund under the Amendment would not be implemented until the expiration of the Fund’s contractual fee waiver. The Board considered that the effective unitary fee rate paid by the Fund under the Agreement after taking into account the contractual fee waiver is less than the effective unitary fee rate that the Fund would pay pursuant to the modified unitary fee rate schedule under the Amendment.
Based on all of the information considered, the Board, including the Independent Trustees, unanimously determined that the terms of the Amendment are fair and reasonable and that the Amendment is in the best interests of the Fund.

Shareholder Letter
First Trust Exchange-Traded Fund III
Semi-Annual Letter from the Chairman and CEO
January 31, 2023
Dear Shareholders,
First Trust is pleased to provide you with the semi-annual report for certain series of First Trust Exchange-Traded Fund III (the “Funds”), which contains detailed information about the Funds for the six-month period ended January 31, 2023.
Given recent inflation data, the Federal Reserve’s (the “Fed”) monetary policy remains front and center in most discussions regarding the outlook of the U.S. economy. Annual revisions to the Consumer Price Index released on February 10, 2023, showed that prices climbed at a 3.3% annual rate in the last three months of 2022, not the 1.8% rate reported four weeks prior, according to Brian Wesbury, Chief Economist at First Trust. Additionally, “core” inflation, which excludes volatile food and energy prices, was also revised upwards from 3.1% to 4.3% over the period. Furthermore, January’s 2023 jobs data came in better than expected, with non-farm payroll employment rising by 517,000. It is precisely this situation: stubbornly high inflation, strong jobs growth and increasing interest rates, which has many pundits debating whether the typical U.S. consumer can remain healthy enough to help ward off an economic recession.
As many investors know, the consumer is an essential driver of economic growth in the U.S. On average, over the 15-year period ended October 1, 2022, consumer spending accounted for 67.8% of the U.S. gross domestic product (“GDP”). Crucially, recent data regarding consumer health has been mixed, in my opinion. On one hand, the Commerce Department reported that in December 2022, the U.S. savings rate rose to its highest level in seven months, coming in at 3.4%. On the other hand, while December’s savings rate was a welcome reversal from the declines suffered throughout 2021 and 2022, it could indicate that consumers are beginning to pull back on discretionary spending amidst a cloudier economic outlook, according to Bloomberg. Recent data shows that the average interest rate on U.S. credit cards rose to 19.07% in the fourth quarter of 2022, its highest level in over 50 years. Additionally, U.S. credit card debt reached a record $930.6 billion in the fourth quarter, jumping 18.5% year-over-year. Even so, debt service payments accounted for just 9.75% of disposable personal income in the third quarter of 2022. This figure is higher than its historic low of 8.33% set in 2021 but is also well below its peak of 13.17% set in 2007. In my view, it is worth keeping an eye on debt service payments. If higher payments lead to a decline in discretionary spending, it could negatively impact GDP.
I would like to take a moment to remind you that even though nearly three years have passed since the World Health Organization initially declared the coronavirus outbreak a global pandemic, the economic impact of worldwide lockdowns and the subsequent governmental stimulus is still very real. China, for example, only recently dropped its requirement that incoming travelers must quarantine before entering the country. In addition, the global economy has yet to fully absorb the impact of the fiscal policies enacted to jump start consumer spending in 2020, in my view. As evidence of this, each of the countries that comprise the G-10 currently has a headline inflation rate that stands well above its stated target. Central banks likely have more work to do, in my opinion.
Thank you for giving First Trust the opportunity to play a role in your financial future. We value our relationship with you and will report on the Funds again in six months.
Sincerely,
James A. Bowen
Chairman of the Board of Trustees
Chief Executive Officer of First Trust Advisors L.P.

Fund Performance Overview (Unaudited) (Continued)
First Trust Short Duration Managed Municipal ETF (FSMB) (Continued)

Performance figures assume reinvestment of all distributions and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. The Fund’s past performance does not predict future performance.

Performance in municipal bond investment strategies can be impacted from the benefits of purchasing odd lot positions. The impact of these investments can be particularly meaningful when funds have limited assets under management and may not be a sustainable source of performance as a fund grows in size.
Frequency Distribution of Discounts and Premiums
Information showing the number of days the market price of the Fund’s shares was greater (at a premium) and less (at a discount) than the Fund’s net asset value for the most recently completed year, and the most recently completed calendar quarters since that year (or life of the Fund, if shorter), is available at https://www.ftportfolios.com/Retail/etf/home.aspx.

(1) The credit quality and ratings information presented above reflect the ratings assigned by one or more nationally recognized statistical rating organizations (NRSROs), including S&P Global Ratings, Moody’s Investors Service, Inc., Fitch Ratings or a comparably rated NRSRO. For situations in which a security is rated by more than one NRSRO and the ratings are not equivalent, the highest rating is used.  Sub-investment grade ratings are those rated BB+/Ba1 or lower. Investment grade ratings are those rated BBB-/Baa3 or higher. The credit ratings shown relate to the creditworthiness of the issuers of the underlying securities in the Fund, and not to the Fund or its shares. Credit ratings are subject to change.

Fund Performance Overview (Unaudited) (Continued)
First Trust Ultra Short Duration Municipal ETF (FUMB) (Continued)

Performance figures assume reinvestment of all distributions and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. The Fund’s past performance does not predict future performance.

Performance in municipal bond investment strategies can be impacted from the benefits of purchasing odd lot positions. The impact of these investments can be particularly meaningful when funds have limited assets under management and may not be a sustainable source of performance as a fund grows in size.
Frequency Distribution of Discounts and Premiums
Information showing the number of days the market price of the Fund’s shares was greater (at a premium) and less (at a discount) than the Fund’s net asset value for the most recently completed year, and the most recently completed calendar quarters since that year (or life of the Fund, if shorter), is available at https://www.ftportfolios.com/Retail/etf/home.aspx.

Notes to Fund Performance Overview (Unaudited)
Total returns for the period since inception are calculated from the inception date of each Fund. “Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated. The total returns would have been lower if certain fees had not been waived by the Advisor.
Each Fund’s per share net asset value (“NAV”) is the value of one share of the Fund and is computed by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of outstanding shares. The price used to calculate market return (“Market Price”) is determined by using the midpoint of the national best bid and offer price (“NBBO”) as of the time that the Fund’s NAV is calculated. Under SEC rules, the NBBO consists of the highest displayed buy and lowest sell prices among the various exchanges trading the Fund at the time the Fund’s NAV is calculated. Prior to January 1, 2019, the price used was the midpoint between the highest bid and the lowest offer on the stock exchange on which shares of the Fund were listed for trading as of the time that the Fund’s NAV was calculated. Since shares of each Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of each Fund is used as a proxy for the secondary market trading price to calculate market returns. NAV and market returns assume that all distributions have been reinvested in each Fund at NAV and Market Price, respectively.
An index is a statistical composite that tracks a specified financial market or sector. Unlike each Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by each Fund. These expenses negatively impact the performance of each Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The total returns presented reflect the reinvestment of dividends on securities in the indices. The returns presented do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of each Fund will vary with changes in market conditions. Shares of each Fund may be worth more or less than their original cost when they are redeemed or sold in the market. Each Fund’s past performance is no guarantee of future performance.

Understanding Your Fund Expenses
January 31, 2023 (Unaudited)
As a shareholder of First Trust Short Duration Managed Municipal ETF or First Trust Ultra Short Duration Municipal ETF (each a “Fund” and collectively, the “Funds”), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs of investing in the Funds and to compare these costs with the ongoing costs of investing in other funds.
The Example is based on an investment of $1,000 invested at the beginning of the period and held through the six-month period ended January 31, 2023.
Actual Expenses
The first line in the following table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During the Six-Month Period” to estimate the expenses you paid on your account during this six-month period.
Hypothetical Example for Comparison Purposes
The second line in the following table provides information about hypothetical account values and hypothetical expenses based on each Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not each Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Funds and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.
Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs such as brokerage commissions. Therefore, the second line in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

(a) This security, sold within the terms of a private placement memorandum, is exempt from registration upon resale under Rule 144A of the Securities Act of 1933, as amended, and may be resold in transactions exempt from registration, normally to qualified institutional buyers. Pursuant to procedures adopted by the Trust’s Board of Trustees, this security has been determined to be liquid by First Trust Advisors L.P. (the “Advisor”).

First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
1. Organization
First Trust Exchange-Traded Fund III (the “Trust”) is an open-end management investment company organized as a Massachusetts business trust on January 9, 2008, and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended (the “1940 Act”).
The Trust currently consists of seventeen funds that are offering shares. This report covers the following funds (each a “Fund” and collectively, the “Funds”), each a diversified series of the Trust:
First Trust Short Duration Managed Municipal ETF – (NYSE Arca, Inc. (“NYSE Arca”) ticker “FSMB”)
First Trust Ultra Short Duration Municipal ETF – (NYSE Arca ticker “FUMB”)
Each Fund represents a separate series of shares of beneficial interest in the Trust. Unlike conventional mutual funds, each Fund issues and redeems shares on a continuous basis, at net asset value (“NAV”), only in large blocks of shares known as “Creation Units.”
Each Fund is an actively managed exchange-traded fund. The investment objective of each Fund is to seek to provide federally tax-exempt income consistent with capital preservation. Under normal market conditions, each Fund seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in municipal debt securities that pay interest that is exempt from regular federal income taxes.
There can be no assurance that a Fund will achieve its investment objective. The Funds may not be appropriate for all investors.
2. Significant Accounting Policies
The Funds are each considered an investment company and follow accounting and reporting guidance under Financial Accounting Standards Board Accounting Standards Codification Topic 946, “Financial Services-Investment Companies.” The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of the financial statements. The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.
A. Portfolio Valuation
Each Fund’s NAV is determined daily as of the close of regular trading on the New York Stock Exchange (“NYSE”), normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. Each Fund’s NAV is calculated by dividing the value of all assets of each Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of shares outstanding.
Each Fund’s investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent readily available market quotations such as last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Pricing Committee of the Funds’ investment advisor, First Trust Advisors L.P. (“First Trust” or the “Advisor”), in accordance with valuation procedures approved by the Trust’s Board of Trustees, and in accordance with provisions of the 1940 Act and rules thereunder. Investments valued by the Advisor’s Pricing Committee, if any, are footnoted as such in the footnotes to the Portfolio of Investments. Each Fund’s investments are valued as follows:
Municipal securities and other debt securities are fair valued on the basis of fair valuations provided by a third-party pricing service approved by the Advisor’s Pricing Committee, which may use the following valuation inputs when available:
1) benchmark yields;
2) reported trades;
3) broker/dealer quotes;
4) issuer spreads;
5) benchmark securities;
6) bids and offers; and
7) reference data including market research publications.

Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but a Fund may hold or transact in such securities in smaller, odd lot sizes. Odd lots may trade at lower prices than institutional round lots.
Exchange-traded futures contracts are valued at the closing price in the market where such contracts are principally traded. If no closing price is available, exchange-traded futures contracts are valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price.
Fixed income and other debt securities having a remaining maturity of sixty days or less when purchased are fair valued at cost adjusted for amortization of premiums and accretion of discounts (amortized cost), provided the Advisor’s Pricing Committee has determined that the use of amortized cost is an appropriate reflection of fair value given market and issuer-specific conditions existing at the time of the determination. Factors that may be considered in determining the appropriateness of the use of amortized cost include, but are not limited to, the following:
1) the credit conditions in the relevant market and changes thereto;
2) the liquidity conditions in the relevant market and changes thereto;
3) the interest rate conditions in the relevant market and changes thereto (such as significant changes in interest rates);
4) issuer-specific conditions (such as significant credit deterioration); and
5) any other market-based data the Advisor’s Pricing Committee considers relevant. In this regard, the Advisor’s Pricing Committee may use last-obtained market-based data to assist it when valuing portfolio securities using amortized cost.
Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Advisor’s Pricing Committee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a third-party pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of a Fund’s NAV or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the third-party pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchanges. A variety of factors may be considered in determining the fair value of such securities, including, but not limited to, the following:
1) the fundamental business data relating to the issuer;
2) an evaluation of the forces which influence the market in which these securities are purchased and sold;
3) the type, size and cost of the security;
4) the financial statements of the issuer;
5) the credit quality and cash flow of the issuer, based on the Advisor’s or external analysis;
6) the information as to any transactions in or offers for the security;
7) the price and extent of public trading in similar securities (or equity securities) of the issuer/borrower, or comparable companies;
8) the coupon payments;
9) the quality, value and salability of collateral, if any, securing the security; and
10) other relevant factors.
The Funds are subject to fair value accounting standards that define fair value, establish the framework for measuring fair value and provide a three-level hierarchy for fair valuation based upon the inputs to the valuation as of the measurement date. The three levels of the fair value hierarchy are as follows:
Level 1 – Level 1 inputs are quoted prices in active markets for identical investments. An active market is a market in which transactions for the investment occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:
o Quoted prices for similar investments in active markets.
Page 47

Notes to Financial Statements (Continued)
First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
o Quoted prices for identical or similar investments in markets that are non-active. A non-active market is a market where there are few transactions for the investment, the prices are not current, or price quotations vary substantially either over time or among market makers, or in which little information is released publicly.
o Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).
o Inputs that are derived principally from or corroborated by observable market data by correlation or other means.
Level 3 – Level 3 inputs are unobservable inputs. Unobservable inputs may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.
The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value each Fund’s investments as of January 31, 2023, is included with each Fund’s Portfolio of Investments.
B. Securities Transactions and Investment Income
Securities transactions are recorded as of the trade date. Realized gains and losses from securities transactions are recorded on the identified cost basis. Interest income is recorded daily on the accrual basis. Amortization of premiums and accretion of discounts are recorded using the effective interest method.
Securities purchased or sold on a when-issued or delayed-delivery basis may have extended settlement periods. The value of the security so purchased is subject to market fluctuations during this period. The Funds maintain liquid assets with a current value at least equal to the amount of its when-issued or delayed-delivery securities. At January 31, 2023, FSMB and FUMB held $7,644,025 and $5,651,053, respectively, of when-issued or delayed-delivery securities.
C. Futures Contracts
FSMB may purchase or sell (i.e., is long or short) exchange-listed futures contracts to hedge against changes in interest rates (interest rate risk). Futures contracts are agreements between the Fund and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and at a specified date. Depending on the terms of the contract, futures contracts are settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date. Open futures contracts can also be closed out prior to settlement by entering into an offsetting transaction in a matching futures contract. If the Fund is not able to enter into an offsetting transaction, the Fund will continue to be required to maintain margin deposits on the futures contract. When the contract is closed or expires, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed or expired. This gain or loss is included in “Net realized gain (loss) on futures contracts” on the Statements of Operations.
Upon entering into a futures contract, the Fund must deposit funds, called margin, with its custodian in the name of the clearing broker equal to a specified percentage of the current value of the contract. Open futures contracts are marked to market daily with the change in value recognized as a component of “Net change in unrealized appreciation (depreciation) on futures contracts” on the Statements of Operations. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are included in “Variation margin” payable or receivable on the Statements of Assets and Liabilities.
If market conditions change unexpectedly, the Fund may not achieve the anticipated benefits of the futures contract and may realize a loss. The use of futures contracts involves the risk of imperfect correlation in movements in the price of the futures contracts, interest rates and the underlying instruments. The Fund did not hold any futures contracts at January 31, 2023.
D. Dividends and Distributions to Shareholders
Dividends from net investment income, if any, are declared and paid monthly by each Fund, or as the Board of Trustees may determine from time to time. Distributions of net realized capital gains earned by each Fund, if any, are distributed at least annually. A Fund may also designate a portion of the amount paid to redeeming shareholders as a distribution for tax purposes.
Distributions from net investment income and realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These permanent differences are primarily due to the varying treatment of income and gain/loss on portfolio securities held by the Funds and have no impact on net assets or NAV per share. Temporary differences, which arise from recognizing certain items of income, expense and gain/loss in different periods for financial statement and tax purposes, will reverse at some time in the future.

E. Income Taxes
Each Fund intends to continue to qualify as a regulated investment company by complying with the requirements under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), which includes distributing substantially all of its net investment income and net realized gains to shareholders. Accordingly, no provision has been made for federal and state income taxes. However, due to the timing and amount of distributions, each Fund may be subject to an excise tax of 4% of the amount by which approximately 98% of each Fund’s taxable income exceeds the distributions from such taxable income for the calendar year.
In addition, each Fund intends to invest in municipal securities to allow it to pay shareholders “exempt dividends” as defined in the Code.
The Funds are subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. Taxable years ended 2019, 2020, 2021, and 2022 remain open to federal and state audit. As of January 31, 2023, management has evaluated the application of these standards to the Funds and has determined that no provision for income tax is required in the Funds’ financial statements for uncertain tax positions.
The Funds intend to utilize provisions of the federal income tax laws, which allow them to carry a realized capital loss forward indefinitely following the year of the loss and offset such loss against any future realized capital gains. The Funds are subject to certain limitations under U.S. tax rules on the use of capital loss carryforwards and net unrealized built-in losses. These limitations apply when there has been a 50% change in ownership. At July 31, 2022, for federal income tax purposes, each Fund had a capital loss carryforward available that is shown in the table below, to the extent provided by regulations, to offset future capital gains.

F. Expenses
Expenses, other than the investment advisory fee and other excluded expenses, are paid by the Advisor (See Note 3).
3. Investment Advisory Fee, Affiliated Transactions and Other Fee Arrangements
First Trust, the investment advisor to the Funds, is a limited partnership with one limited partner, Grace Partners of DuPage L.P., and one general partner, The Charger Corporation. The Charger Corporation is an Illinois corporation controlled by James A. Bowen, Chief Executive Officer of First Trust. First Trust is responsible for the selection and ongoing monitoring of the securities in each Fund’s portfolio, managing the Funds’ business affairs and providing certain administrative services necessary for the management of the Funds.
Pursuant to the Investment Management Agreement between First Trust and the Trust, First Trust manages the investment of the Funds’ assets and is responsible for the expenses of each Fund, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees payable pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses, which are paid by each respective Fund. Effective November 1, 2022, the annual unitary management fee payable by each Fund to First Trust for these services will be reduced at certain levels of each Fund’s net assets (“breakpoints”) and calculated pursuant to the schedules below.
Breakpoints   FSMB   FUMB
Fund net assets up to and including $2.5 billion   0.55000%   0.45000%
Fund net assets greater than $2.5 billion up to and including $5 billion   0.53625%   0.43875%
Fund net assets greater than $5 billion up to and including $7.5 billion   0.52250%   0.42750%
Fund net assets greater than $7.5 billion up to and including $10 billion   0.50875%   0.41625%
Fund net assets greater than $10 billion   0.49500%   0.40500%
Prior to November 1, 2022, FSMB and FUMB paid First Trust an annual unitary management fee of 0.55% and 0.45% of FSMB’s and FUMB’s average daily net assets, respectively. First Trust also provides fund reporting services to each Fund for a flat annual fee in the amount of $9,250, which is covered under the annual unitary management fee.
Pursuant to two separate contractual agreements for each Fund, First Trust agreed to waive management fees of 0.20% of average daily net assets for each Fund until November 30, 2022. As of November 30, 2022, the waiver agreements terminated. First Trust does not have the right to recover the fees waived. During the six months ended January 31, 2023, the Advisor waived fees of $232,733 and $208,049 for FSMB and FUMB, respectively.
The Trust has multiple service agreements with Brown Brothers Harriman & Co. (“BBH”). Under the service agreements, BBH performs custodial, fund accounting, certain administrative services, and transfer agency services for the Funds. As custodian, BBH is responsible for custody of each Fund’s assets. As fund accountant and administrator, BBH is responsible for maintaining the books and records of each Fund’s securities and cash. As transfer agent, BBH is responsible for maintaining shareholder records for each Fund.
Each Trustee who is not an officer or employee of First Trust, any sub-advisor or any of their affiliates (“Independent Trustees”) is paid a fixed annual retainer that is allocated equally among each fund in the First Trust Fund Complex. Each Independent Trustee is also paid an annual per fund fee that varies based on whether the fund is a closed-end or other actively managed fund, a target outcome fund or an index fund.
Additionally, the Lead Independent Trustee and the Chairs of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in
Page 50

First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
the First Trust Fund Complex based on net assets. Independent Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairs rotate every three years. The officers and “Interested” Trustee receive no compensation from the Trust for acting in such capacities.
4. Purchases and Sales of Securities
For the six months ended January 31, 2023, the cost of purchases and proceeds from sales of investment securities for each Fund, excluding short-term investments and in-kind transactions, were as follows:
  Purchases   Sales
First Trust Short Duration Managed Municipal ETF $ 214,510,843   $ 84,314,199
First Trust Ultra Short Duration Municipal ETF  182,138,342    158,034,392
       
For the six months ended January 31, 2023, the Funds had no in-kind transactions.
5. Creations, Redemptions and Transaction Fees
Each Fund generally issues and redeems its shares in primary market transactions through a creation and redemption mechanism and does not sell or redeem individual shares. Instead, financial entities known as “Authorized Participants” have contractual arrangements with a Fund or one of the Fund’s service providers to purchase and redeem Fund shares directly with the Fund in large blocks of shares known as “Creation Units.” Prior to the start of trading on every business day, a Fund publishes through the National Securities Clearing Corporation (“NSCC”) the “basket” of securities, cash or other assets that it will accept in exchange for a Creation Unit of the Fund’s shares. An Authorized Participant that wishes to effectuate a creation of a Fund’s shares deposits with the Fund the “basket” of securities, cash or other assets identified by the Fund that day, and then receives the Creation Unit of the Fund’s shares in return for those assets. After purchasing a Creation Unit, the Authorized Participant may continue to hold the Fund’s shares or sell them in the secondary market. The redemption process is the reverse of the purchase process: the Authorized Participant redeems a Creation Unit of a Fund’s shares for a basket of securities, cash or other assets. The combination of the creation and redemption process with secondary market trading in a Fund’s shares and underlying securities provides arbitrage opportunities that are designed to help keep the market price of a Fund’s shares at or close to the NAV per share of the Fund.
Each Fund imposes fees in connection with the purchase of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price for each Creation Unit will equal the daily NAV per share of a Fund times the number of shares in a Creation Unit, plus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the creation basket.
Each Fund also imposes fees in connection with the redemption of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price received for each Creation Unit will equal the daily NAV per share of a Fund times the number of shares in a Creation Unit, minus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the redemption basket. Investors who use the services of a broker or other such intermediary in addition to an Authorized Participant to effect a redemption of a Creation Unit may also be assessed an amount to cover the cost of such services. The redemption fee charged by a Fund will comply with Rule 22c-2 of the 1940 Act which limits redemption fees to no more than 2% of the value of the shares redeemed.
6. Distribution Plan
The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, each Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. (“FTP”), the distributor of the Funds, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or to provide investor services. FTP may also use this amount to compensate securities dealers or other persons that are Authorized Participants for providing distribution assistance, including broker-dealer and shareholder support and educational and promotional services.
No 12b-1 fees are currently paid by the Funds, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before November 30, 2023.

7. Indemnification
The Trust, on behalf of the Funds, has a variety of indemnification obligations under contracts with its service providers. The Trust’s maximum exposure under these arrangements is unknown. However, the Trust has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.
8. Subsequent Events
Management has evaluated the impact of all subsequent events to the Funds through the date the financial statements were issued and has determined that there were no subsequent events requiring recognition or disclosure in the financial statements that have not already been disclosed.

Proxy Voting Policies and Procedures
A description of the policies and procedures that the Trust uses to determine how to vote proxies and information on how each Fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available (1) without charge, upon request, by calling (800) 988-5891; (2) on each Fund’s website at www.ftportfolios.com; and (3) on the Securities and Exchange Commission’s (“SEC”) website at www.sec.gov.
Portfolio Holdings
Each Fund files portfolio holdings information for each month in a fiscal quarter within 60 days after the end of the relevant fiscal quarter on Form N-PORT. Portfolio holdings information for the third month of each fiscal quarter will be publicly available on the SEC’s website at www.sec.gov. Each Fund’s complete schedule of portfolio holdings for the second and fourth quarters of each fiscal year is included in the semi-annual and annual reports to shareholders, respectively, and is filed with the SEC on Form N-CSR. The semi-annual and annual report for each Fund is available to investors within 60 days after the period to which it relates. Each Fund’s Forms N-PORT and Forms N-CSR are available on the SEC’s website listed above.
Risk Considerations
Risks are inherent in all investing. Certain general risks that may be applicable to a Fund are identified below, but not all of the material risks relevant to each Fund are included in this report and not all of the risks below apply to each Fund. The material risks of investing in each Fund are spelled out in its prospectus, statement of additional information and other regulatory filings. Before investing, you should consider each Fund’s investment objective, risks, charges and expenses, and read each Fund’s prospectus and statement of additional information carefully. You can download each Fund’s prospectus at www.ftportfolios.com or contact First Trust Portfolios L.P. at (800) 621-1675 to request a prospectus, which contains this and other information about each Fund.
Concentration Risk. To the extent that a fund is able to invest a significant percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the fund’s investments more than if the fund were more broadly diversified. A fund that tracks an index will be concentrated to the extent the fund’s corresponding index is concentrated. A concentration makes a fund more susceptible to any single occurrence and may subject the fund to greater market risk than a fund that is more broadly diversified.
Credit Risk. Credit risk is the risk that an issuer of a security will be unable or unwilling to make dividend, interest and/or principal payments when due and the related risk that the value of a security may decline because of concerns about the issuer’s ability to make such payments.
Cyber Security Risk. The funds are susceptible to potential operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause a fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause a fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. In addition, cyber security breaches of a fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, or issuers in which the fund invests, can also subject a fund to many of the same risks associated with direct cyber security breaches.
Defined Outcome Funds Risk. To the extent a fund’s investment strategy is designed to deliver returns tied to the price performance of an underlying ETF, an investor may not realize the returns the fund seeks to achieve if that investor does not hold shares for the entire target outcome period. In the event an investor purchases shares after the first day of the target outcome period or sells shares prior to the end of the target outcome period, the buffer that the fund seeks to provide against a decline in the value of the underlying ETF may not be available, the enhanced returns that the fund seeks to provide (if any) may not be available and the investor may not participate in a gain in the value of the underlying ETF up to the cap for the investor’s investment period. Additionally, the fund will not participate in gains of the underlying ETF above the cap and a shareholder may lose their entire investment. If the fund seeks enhanced returns, there are certain time periods when the value of the fund may fall faster than the value of the underlying ETF, and it is very unlikely that, on any given day during which the underlying ETF share price increases in value, the fund’s share price will increase at the same rate as the enhanced returns sought by the fund, which is designed for an entire target outcome period. Trading flexible exchange options involves risks different from, or possibly greater than, the risks associated with investing directly in securities, such as less liquidity and correlation and valuation risks. A fund may experience substantial downside from specific flexible exchange option positions and certain positions may expire worthless.
Derivatives Risk. To the extent a fund uses derivative instruments such as futures contracts, options contracts and swaps, the fund may experience losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified
Page 53

Additional Information (Continued)
First Trust Exchange-Traded Fund III
January 31, 2023 (Unaudited)
by certain features of the derivative. These risks are heightened when a fund’s portfolio managers use derivatives to enhance the fund’s return or as a substitute for a position or security, rather than solely to hedge (or offset) the risk of a position or security held by the fund.
Equity Securities Risk. To the extent a fund invests in equity securities, the value of the fund’s shares will fluctuate with changes in the value of the equity securities. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant stock market, such as market volatility, or when political or economic events affecting the issuers occur. In addition, common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market.
ETF Risk. The shares of an ETF trade like common stock and represent an interest in a portfolio of securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities, although lack of liquidity in an ETF could result in it being more volatile and ETFs have management fees that increase their costs. Shares of an ETF trade on an exchange at market prices rather than net asset value, which may cause the shares to trade at a price greater than net asset value (premium) or less than net asset value (discount). In times of market stress, decisions by market makers to reduce or step away from their role of providing a market for an ETF’s shares, or decisions by an ETF’s authorized participants that they are unable or unwilling to proceed with creation and/or redemption orders of an ETF’s shares, could result in shares of the ETF trading at a discount to net asset value and in greater than normal intraday bid-ask spreads.
Fixed Income Securities Risk. To the extent a fund invests in fixed income securities, the fund will be subject to credit risk, income risk, interest rate risk, liquidity risk and prepayment risk. Income risk is the risk that income from a fund’s fixed income investments could decline during periods of falling interest rates. Interest rate risk is the risk that the value of a fund’s fixed income securities will decline because of rising interest rates. Liquidity risk is the risk that a security cannot be purchased or sold at the time desired, or cannot be purchased or sold without adversely affecting the price. Prepayment risk is the risk that the securities will be redeemed or prepaid by the issuer, resulting in lower interest payments received by the fund. In addition to these risks, high yield securities, or “junk” bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and the market for high yield securities is generally smaller and less liquid than that for investment grade securities.
Index or Model Constituent Risk. Certain funds may be a constituent of one or more indices or ETF models. As a result, such a fund may be included in one or more index-tracking exchange-traded funds or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving a fund, the size of the fund and the market volatility of the fund. Inclusion in an index could increase demand for the fund and removal from an index could result in outsized selling activity in a relatively short period of time. As a result, a fund’s net asset value could be negatively impacted and the fund’s market price may be significantly below its net asset value during certain periods. In addition, index rebalances may potentially result in increased trading activity in a fund’s shares.
Index Provider Risk. To the extent a fund seeks to track an index, it is subject to Index Provider Risk. There is no assurance that the Index Provider will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, the Index Provider may carry out an unscheduled rebalance or other modification of the Index constituents or weightings, which may increase the fund’s costs. The Index Provider does not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and it does not guarantee that the Index will be calculated in accordance with its stated methodology. Losses or costs associated with any Index Provider errors generally will be borne by the fund and its shareholders.
Investment Companies Risk. To the extent a fund invests in the securities of other investment vehicles, the fund will incur additional fees and expenses that would not be present in a direct investment in those investment vehicles. Furthermore, the fund’s investment performance and risks are directly related to the investment performance and risks of the investment vehicles in which the fund invests.
LIBOR Risk. To the extent a fund invests in floating or variable rate obligations that use the London Interbank Offered Rate (“LIBOR”) as a reference interest rate, it is subject to LIBOR Risk. The United Kingdom’s Financial Conduct Authority, which regulates LIBOR has ceased making LIBOR available as a reference rate over a phase-out period that began December 31, 2021. There is no assurance that any alternative reference rate, including the Secured Overnight Financing Rate (“SOFR”) will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. The unavailability or replacement of LIBOR may affect the value, liquidity or return on certain fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any potential effects of the transition away from LIBOR on the fund or on certain instruments in which the fund invests can be difficult to ascertain, and they may vary depending on a variety of factors, and they could result in losses to the fund.

Management Risk. To the extent that a fund is actively managed, it is subject to management risk. In managing an actively-managed fund’s investment portfolio, the fund’s portfolio managers will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that a fund will meet its investment objective.
Market Risk. Market risk is the risk that a particular security, or shares of a fund in general, may fall in value. Securities held by a fund, as well as shares of a fund itself, are subject to market fluctuations caused by factors such as general economic conditions, political events, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of a fund could decline in value or underperform other investments as a result of the risk of loss associated with these market fluctuations. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on a fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. In February 2022, Russia invaded Ukraine which has caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, and the United States. The hostilities and sanctions resulting from those hostilities could have a significant impact on certain fund investments as well as fund performance. The COVID-19 global pandemic and the ensuing policies enacted by governments and central banks have caused and may continue to cause significant volatility and uncertainty in global financial markets. While the U.S. has resumed “reasonably” normal business activity, many countries continue to impose lockdown measures. Additionally, there is no guarantee that vaccines will be effective against emerging variants of the disease. These events also adversely affect the prices and liquidity of a fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of a fund’s shares and result in increased market volatility. During any such events, a fund’s shares may trade at increased premiums or discounts to their net asset value and the bid/ask spread on a fund’s shares may widen.
Non-U.S. Securities Risk. To the extent a fund invests in non-U.S. securities, it is subject to additional risks not associated with securities of domestic issuers. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to: possible adverse political, social or economic developments; restrictions on foreign investment or exchange of securities; capital controls; lack of liquidity; currency exchange rates; excessive taxation; government seizure of assets; the imposition of sanctions by foreign governments; different legal or accounting standards; and less government supervision and regulation of exchanges in foreign countries. Investments in non-U.S. securities may involve higher costs than investments in U.S. securities, including higher transaction and custody costs, as well as additional taxes imposed by non-U.S. governments. These risks may be heightened for securities of companies located, or with significant operations, in emerging market countries.
Operational Risk. Each fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of a fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. Each fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect a fund’s ability to meet its investment objective. Although the funds and the funds’ investment advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.
Passive Investment Risk. To the extent a fund seeks to track an index, the fund will invest in the securities included in, or representative of, the index regardless of their investment merit. A fund generally will not attempt to take defensive positions in declining markets.
Preferred Securities Risk. Preferred securities combine some of the characteristics of both common stocks and bonds. Preferred securities are typically subordinated to bonds and other debt securities in a company’s capital structure in terms of priority to corporate income, subjecting them to greater credit risk than those debt securities. Generally, holders of preferred securities have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may obtain limited rights. In certain circumstances, an issuer of preferred securities may defer payment on the securities and, in some cases, redeem the securities prior to a specified date. Preferred securities may also be substantially less liquid than other securities, including common stock.
Valuation Risk. The valuation of certain securities may carry more risk than that of common stock. Uncertainties in the conditions of the financial markets, unreliable reference data, lack of transparency and inconsistency of valuation models and processes may lead to inaccurate asset pricing. A fund may hold investments in sizes smaller than institutionally sized round lot positions (sometimes referred to as odd lots). However, third-party pricing services generally provide evaluations on the basis of institutionally-sized round lots. If a fund sells certain of its investments in an odd lot transaction, the sale price may be less than the value at which such securities
Page 55

have been held by the fund. Odd lots often trade at lower prices than institutional round lots. There is no assurance that the fund will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to the fund.

Advisory Agreement
Board Considerations Regarding Approval of Amendment to the Investment Management Agreement
The Board of Trustees of First Trust Exchange-Traded Fund III (the “Trust”), including the Independent Trustees, unanimously approved the amendment (the “Amendment”) of the Investment Management Agreement (the “Agreement”) with First Trust Advisors L.P. (the “Advisor”) on behalf of the following two series of the Trust (each a “Fund” and collectively, the “Funds”):
First Trust Short Duration Managed Municipal ETF (FSMB)
First Trust Ultra Short Duration Municipal ETF (FUMB)
The Board approved the Amendment for each Fund at a meeting held on October 24, 2022.  As part of the review process, the Board reviewed information and had preliminary discussions with the Advisor regarding the proposed Amendment at meetings held on April 18, 2022, June 12–13, 2022 and September 18–19, 2022.  Following those preliminary discussions, the Board requested and received information from the Advisor regarding the proposed Amendment, and that information was considered at an executive session of the Independent Trustees and their counsel held prior to the October 24, 2022 meeting, as well as at the October meeting.
In reviewing the Amendment for each Fund, the Board considered that the purpose of the Amendment is to modify the unitary fee rate for each Fund under the Agreement by introducing a breakpoint schedule pursuant to which the unitary fee rate paid by each Fund to the Advisor will be reduced as assets of such Fund meet certain thresholds.  The Board noted the Advisor’s representations that the quality and quantity of the services provided to each Fund by the Advisor under the Agreement will not be reduced or modified as a result of the Amendment, and that the obligations of the Advisor under the Agreement will remain the same in all respects.
The Board noted that it, including the Independent Trustees, last approved the continuation of the Agreement for each Fund for a one-year period ending June 30, 2023 at a meeting held on June 12–13, 2022.  The Board noted that in connection with such approval it had determined for each Fund, based upon the information provided, that the terms of the Agreement were fair and reasonable and that the continuation of the Agreement was in the best interests of the Fund in light of the nature, extent and quality of the services provided and such other matters as the Board considered to be relevant in the exercise of its business judgment. 
The Board noted that the Advisor had previously agreed to waive a portion of its unitary fee for each Fund and that the modified unitary fee rate schedule for each Fund under the Amendment would not be implemented until the expiration of the Fund’s contractual fee waiver.  The Board considered that the effective unitary fee rate paid by each Fund under the Agreement after taking into account the contractual fee waiver is less than the effective unitary fee rate that the Fund would pay pursuant to the modified unitary fee rate schedule under the Amendment.
Based on all of the information considered, the Board, including the Independent Trustees, unanimously determined that the terms of the Amendment are fair and reasonable and that the Amendment is in the best interests of each Fund.

Shareholder Letter
First Trust Merger Arbitrage ETF (MARB)
Semi-Annual Letter from the Chairman and CEO
January 31, 2023
Dear Shareholders,
First Trust is pleased to provide you with the semi-annual report for the First Trust Merger Arbitrage ETF (the “Fund”), which contains detailed information about the Fund for the six-month period ended January 31, 2023.
Given recent inflation data, the Federal Reserve’s (the “Fed”) monetary policy remains front and center in most discussions regarding the outlook of the U.S. economy. Annual revisions to the Consumer Price Index released on February 10, 2023, showed that prices climbed at a 3.3% annual rate in the last three months of 2022, not the 1.8% rate reported four weeks prior, according to Brian Wesbury, Chief Economist at First Trust. Additionally, “core” inflation, which excludes volatile food and energy prices, was also revised upwards from 3.1% to 4.3% over the period. Furthermore, January’s 2023 jobs data came in better than expected, with non-farm payroll employment rising by 517,000. It is precisely this situation: stubbornly high inflation, strong jobs growth and increasing interest rates, which has many pundits debating whether the typical U.S. consumer can remain healthy enough to help ward off an economic recession.
As many investors know, the consumer is an essential driver of economic growth in the U.S. On average, over the 15-year period ended October 1, 2022, consumer spending accounted for 67.8% of the U.S. gross domestic product (“GDP”). Crucially, recent data regarding consumer health has been mixed, in my opinion. On one hand, the Commerce Department reported that in December 2022, the U.S. savings rate rose to its highest level in seven months, coming in at 3.4%. On the other hand, while December’s savings rate was a welcome reversal from the declines suffered throughout 2021 and 2022, it could indicate that consumers are beginning to pull back on discretionary spending amidst a cloudier economic outlook, according to Bloomberg. Recent data shows that the average interest rate on U.S. credit cards rose to 19.07% in the fourth quarter of 2022, its highest level in over 50 years. Additionally, U.S. credit card debt reached a record $930.6 billion in the fourth quarter, jumping 18.5% year-over-year. Even so, debt service payments accounted for just 9.75% of disposable personal income in the third quarter of 2022. This figure is higher than its historic low of 8.33% set in 2021 but is also well below its peak of 13.17% set in 2007. In my view, it is worth keeping an eye on debt service payments. If higher payments lead to a decline in discretionary spending, it could negatively impact GDP.
I would like to take a moment to remind you that even though nearly three years have passed since the World Health Organization initially declared the coronavirus outbreak a global pandemic, the economic impact of worldwide lockdowns and the subsequent governmental stimulus is still very real. China, for example, only recently dropped its requirement that incoming travelers must quarantine before entering the country. In addition, the global economy has yet to fully absorb the impact of the fiscal policies enacted to jump start consumer spending in 2020, in my view. As evidence of this, each of the countries that comprise the G-10 currently has a headline inflation rate that stands well above its stated target. Central banks likely have more work to do, in my opinion.
Thank you for giving First Trust the opportunity to play a role in your financial future. We value our relationship with you and will report on the Fund again in six months.
Sincerely,
James A. Bowen
Chairman of the Board of Trustees
Chief Executive Officer of First Trust Advisors L.P.

Fund Performance Overview (Unaudited)
First Trust Merger Arbitrage ETF (MARB)
The First Trust Merger Arbitrage ETF’s (the “Fund”) investment objective is to seek to provide investors with capital appreciation. Under normal market conditions, the Fund seeks to achieve its investment objective by establishing long and short positions in the equity securities of companies that are involved in a publicly-announced significant corporate event, such as a merger or acquisition. The Fund’s portfolio may include equity securities issued by U.S. and non-U.S. companies, including American Depositary Receipts, and derivatives, including total return swaps. The Fund may invest in securities issued by small, mid and large capitalization issuers. The Fund lists and principally trades its shares on NYSE Arca, Inc. under the ticker symbol “MARB.”

Total returns for the period since inception are calculated from the inception date of the Fund. “Average Annual Total Returns” represent the average annual change in value of an investment over the period indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.
The Fund’s per share net asset value (“NAV”) is the value of one share of the Fund and is computed by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of outstanding shares. The price used to calculate market return (“Market Price”) is determined by using the midpoint of the national best bid and offer price (“NBBO”) as of the time that the Fund’s NAV is calculated. Under SEC rules, the NBBO consists of the highest displayed buy and lowest sell prices among the various exchanges trading the Fund at the time the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after its inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the secondary market trading price to calculate market returns. NAV and market returns assume that all distributions have been reinvested in the Fund at NAV and Market Price, respectively.
An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The total returns presented reflect the reinvestment of dividends on securities in the indices. The returns presented do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future performance.

Understanding Your Fund Expenses
January 31, 2023 (Unaudited)
As a shareholder of the First Trust Merger Arbitrage ETF (the “Fund”), you incur two types of costs: (1) transaction costs; and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, if any, and other Fund expenses. This Example is intended to help you understand your ongoing costs of investing in the Fund and to compare these costs with the ongoing costs of investing in other funds.
The Example is based on an investment of $1,000 invested at the beginning of the period and held through the six-month period ended January 31, 2023.
Actual Expenses
The first line in the following table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During the Six-Month Period” to estimate the expenses you paid on your account during this six-month period.
Hypothetical Example for Comparison Purposes
The second line in the following table provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.
Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs such as brokerage commissions. Therefore, the second line in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Notes to Financial Statements
First Trust Merger Arbitrage ETF (MARB)
January 31, 2023 (Unaudited)
1. Organization
First Trust Exchange-Traded Fund III (the “Trust”) is an open-end management investment company organized as a Massachusetts business trust on January 9, 2008, and is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended (the “1940 Act”).
The Trust currently consists of seventeen funds that are offering shares. This report covers the First Trust Merger Arbitrage ETF (the “Fund”), a non-diversified series of the Trust, which trades under the ticker “MARB” on NYSE Arca, Inc. The Fund represents a separate series of beneficial interest in the Trust. Unlike conventional mutual funds, the Fund issues and redeems shares on a continuous basis, at net asset value (“NAV”), only in large blocks of shares known as “Creation Units.”
The Fund is an actively managed exchange-traded fund. The investment objective of the Fund is to seek to provide investors with capital appreciation. Under normal market conditions, the Fund seeks to achieve its investment objective by establishing long and short positions in the equity securities of companies that are involved in a publicly-announced significant corporate event, such as a merger or acquisition. The Fund’s portfolio may include equity securities issued by U.S. and non-U.S. companies, including American Depositary Receipts, and derivatives, including total return swaps. The Fund may invest in securities issued by small, mid and large capitalization issuers.
2. Significant Accounting Policies
The Fund is considered an investment company and follows accounting and reporting guidance under Financial Accounting Standards Board Accounting Standards Codification Topic 946, “Financial Services-Investment Companies.” The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of the financial statements. The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.
A. Portfolio Valuation
The Fund’s NAV is determined daily as of the close of regular trading on the New York Stock Exchange (“NYSE”), normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. Foreign securities are priced using data reflecting the earlier closing of the principal markets for those securities. The Fund’s NAV is calculated by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of shares outstanding.
The Fund’s investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent readily available market quotations such as last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Pricing Committee of the Fund’s investment advisor, First Trust Advisors L.P. (“First Trust” or the “Advisor”), in accordance with valuation procedures approved by the Trust’s Board of Trustees, and in accordance with provisions of the 1940 Act and rules thereunder. Investments valued by the Advisor’s Pricing Committee, if any, are footnoted as such in the footnotes to the Portfolio of Investments. The Fund’s investments are valued as follows:
Common stocks and other equity securities listed on any national or foreign exchange (excluding The Nasdaq Stock Market LLC (“Nasdaq”) and the London Stock Exchange Alternative Investment Market (“AIM”)) are valued at the last sale price on the exchange on which they are principally traded or, for Nasdaq and AIM securities, the official closing price. Securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, at the close of the securities exchange representing the primary exchange for such securities.
Securities traded in an over-the-counter market are valued at the mean of their most recent bid and asked price, if available, and otherwise at their last trade price.
Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Advisor’s Pricing Committee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a third-party pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of the Fund’s NAV or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the third-party pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might
Page 12

Notes to Financial Statements (Continued)
First Trust Merger Arbitrage ETF (MARB)
January 31, 2023 (Unaudited)
reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchanges. A variety of factors may be considered in determining the fair value of such securities, including, but not limited to, the following:
1) the last sale price on the exchange on which they are principally traded or, for Nasdaq and AIM securities, the official closing price;
2) the type of security;
3) the size of the holding;
4) the initial cost of the security;
5) transactions in comparable securities;
6) price quotes from dealers and/or third-party pricing services;
7) relationships among various securities;
8) information obtained by contacting the issuer, analysts, or the appropriate stock exchange;
9) an analysis of the issuer’s financial statements;
10) the existence of merger proposals or tender offers that might affect the value of the security; and
11) other relevant factors.
The Fund is subject to fair value accounting standards that define fair value, establish the framework for measuring fair value and provide a three-level hierarchy for fair valuation based upon the inputs to the valuation as of the measurement date. The three levels of the fair value hierarchy are as follows:
Level 1 – Level 1 inputs are quoted prices in active markets for identical investments. An active market is a market in which transactions for the investment occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:
o Quoted prices for similar investments in active markets.
o Quoted prices for identical or similar investments in markets that are non-active. A non-active market is a market where there are few transactions for the investment, the prices are not current, or price quotations vary substantially either over time or among market makers, or in which little information is released publicly.
o Inputs other than quoted prices that are observable for the investment (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates).
o Inputs that are derived principally from or corroborated by observable market data by correlation or other means.
Level 3 – Level 3 inputs are unobservable inputs. Unobservable inputs may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.
The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments. A summary of the inputs used to value the Fund’s investments as of January 31, 2023, is included with the Fund’s Portfolio of Investments.
B. Securities Transactions and Investment Income
Securities transactions are recorded as of the trade date. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recorded on the ex-dividend date. Interest income, if any, is recorded daily on the accrual basis.
Distributions received from the Fund’s investments in real estate investment trusts (“REITs”) may be comprised of return of capital, capital gains, and income. The actual character of the amounts received during the year are not known until after the REITs’ fiscal year end. The Fund records the character of distributions received from the REITs during the year based on estimates available. The characterization of distributions received by the Fund may be subsequently revised based on information received from the REITs after their tax reporting periods conclude.
The United Kingdom’s Financial Conduct Authority (the “FCA”), which regulates the London Interbank Offered Rates (“LIBOR”), announced on March 5, 2021 that it intended to phase-out all LIBOR reference rates, beginning December 31, 2021. Since that announcement, the FCA has ceased publication of all non-USD LIBOR reference rates and the 1-week and 2-month USD LIBOR reference rates as of December 31, 2021. The remaining USD LIBOR settings will cease to be published or no longer be representative immediately after June 30, 2023. The International Swaps and Derivatives Association, Inc. (“ISDA”) confirmed that the FCA’s
Page 13

Notes to Financial Statements (Continued)
First Trust Merger Arbitrage ETF (MARB)
January 31, 2023 (Unaudited)
March 5, 2021 announcement of its intention to cease providing LIBOR reference rates, constituted an index cessation event under the Interbank Offered Rates (“IBOR”) Fallbacks Supplement and the ISDA 2020 IBOR Fallbacks Protocol for all 35 LIBOR settings and confirmed that the spread adjustment to be used in ISDA fallbacks was fixed as of the date of the announcement.
In the United States, the Alternative Reference Rates Committee (the “ARRC”), a group of market participants convened by the Board of Governors of the Federal Reserve System and the Federal Reserve Bank of New York in cooperation with other federal and state government agencies, has since 2014 undertaken efforts to identify U.S. dollar reference interest rates as alternatives to LIBOR and to facilitate the mitigation of LIBOR-related risks. In June 2017, the ARRC identified the Secured Overnight Financing Rate (“SOFR”), a broad measure of the cost of cash overnight borrowing collateralized by U.S. Treasury securities, as the preferred alternative for U.S. dollar LIBOR. The Federal Reserve Bank of New York began daily publishing of SOFR in April 2018. There is no assurance that any alternative reference rate, including SOFR, will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity.
At this time, it is not possible to predict the full impact of the elimination of LIBOR and the establishment of an alternative reference rate on the Fund or its investments.
C. Short Sales
Short sales are utilized for investment and risk management purposes and are transactions in which securities or other instruments (such as options, forwards, futures or other derivative contracts) are sold by the Fund, but are not currently owned in the Fund’s portfolio. When the Fund engages in a short sale, the Fund must borrow the security sold short and deliver the security to the counterparty. Short selling allows the Fund to profit from a decline in a market price to the extent such decline exceeds the transaction costs and the costs of borrowing the securities. The Fund will pay a fee or premium to borrow the securities sold short and is obligated to repay the lenders of the securities. Any dividends or interest that accrues on the securities during the period of the loan are due to the lenders. A gain, limited to the price at which the security was sold short, or a loss, unlimited in size, will be recognized upon the termination of the short sale; which is affected by the Fund purchasing the security sold short and delivering the security to the lender. Any such gain or loss may be offset, completely or in part, by the change in the value of the long portion of the Fund’s portfolio. The Fund is subject to the risk that it may be unable to reacquire a security to terminate a short position except at a price substantially in excess of the last quoted price. Also, there is the risk that the counterparty to a short sale may fail to honor its contractual terms, causing a loss to the Fund.
The Fund has established an account with BNP Paribas Prime Brokerage International, Ltd. for the purpose of borrowing securities that the Fund intends to sell short. The Fund is charged interest on debit margin balances at a rate equal to the Overnight Bank Funding Rate plus 85 basis points. With regard to securities held short, the Fund is credited a rebate equal to the market value of its short positions at a rate equal to the Overnight Bank Funding Rate less 35 basis points. This rebate rate applies to easy to borrow securities. Securities that are hard to borrow may earn a rebate that is less than the foregoing or may be subject to a premium charge on a security by security basis. The different rebate rate is determined at the time of a short sale request. For the six months ended January 31, 2023, the Fund had margin interest rebate of $153,784 as shown on the Statement of Operations. Restricted cash in the amount of $17,283,169, as shown on the Statement of Assets and Liabilities, is associated with collateral at the broker as of January 31, 2023.
D. Dividends and Distributions to Shareholders
Dividends from net investment income, if any, are declared and paid quarterly by the Fund, or as the Board of Trustees may determine from time to time. Distributions of net realized capital gains earned by the Fund, if any, are distributed at least annually. The Fund may also designate a portion of the amount paid to redeeming shareholders as a distribution for tax purposes.
Distributions from net investment income and realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These permanent differences are primarily due to the varying treatment of income and gain/loss on portfolio securities held by the Fund and have no impact on net assets or NAV per share. Temporary differences, which arise from recognizing certain items of income, expense and gain/loss in different periods for financial statement and tax purposes, will reverse at some time in the future.
During the fiscal year ended July 31, 2022, no distributions were paid by the Fund.
Page 14

Notes to Financial Statements (Continued)
First Trust Merger Arbitrage ETF (MARB)
January 31, 2023 (Unaudited)
As of July 31, 2022, the components of distributable earnings on a tax basis were as follows:
Undistributed ordinary income

$
Accumulated capital and other gain (loss)

(130,900)
Net unrealized appreciation (depreciation)

164,797
E. Income Taxes
The Fund intends to continue to qualify as a regulated investment company by complying with the requirements under Subchapter M of the Internal Revenue Code of 1986, as amended, which includes distributing substantially all of its net investment income and net realized gains to shareholders. Accordingly, no provision has been made for federal and state income taxes. However, due to the timing and amount of distributions, the Fund may be subject to an excise tax of 4% of the amount by which approximately 98% of the Fund’s taxable income exceeds the distributions from such taxable income for the calendar year.
The Fund is subject to accounting standards that establish a minimum threshold for recognizing, and a system for measuring, the benefits of a tax position taken or expected to be taken in a tax return. Taxable periods ended 2020, 2021, and 2022 remain open to federal and state audit. As of January 31, 2023, management has evaluated the application of these standards to the Fund and has determined that no provision for income tax is required in the Fund’s financial statements for uncertain tax positions.
The Fund intends to utilize provisions of the federal income tax laws, which allow it to carry a realized capital loss forward indefinitely following the year of the loss and offset such loss against any future realized capital gains. The Fund is subject to certain limitations under U.S. tax rules on the use of capital loss carryforwards and net unrealized built-in losses. These limitations apply when there has been a 50% change in ownership. At July 31, 2022, for federal income tax purposes, the Fund had $52,719 of capital loss carryforward available, to the extent provided by regulations, to offset future capital gains.
During the fiscal year ended July 31, 2022, the Fund utilized $215,101 of capital loss carryforwards.
Certain losses realized during the current fiscal year may be deferred and treated as occurring on the first day of the following fiscal year for federal income tax purposes. For the fiscal year ended July 31, 2022, the Fund incurred and elected to defer net ordinary losses of $78,181.
As of January 31, 2023, the aggregate cost, gross unrealized appreciation, gross unrealized depreciation, and net unrealized appreciation/(depreciation) on investments (including short positions and derivatives, if any) for federal income tax purposes were as follows:
Tax Cost   Gross
Unrealized
Appreciation
  Gross
Unrealized
(Depreciation)
  Net Unrealized

(Depreciation)
$41,722,850   $965,325   $(1,894,443)   $(929,118)
F. Expenses
Expenses, other than the investment advisory fee, dividend and interest expenses on investments sold short and other excluded expenses, are paid by the Advisor (See Note 3).
3. Investment Advisory Fee, Affiliated Transactions and Other Fee Arrangements
First Trust, the investment advisor to the Fund, is a limited partnership with one limited partner, Grace Partners of DuPage L.P., and one general partner, The Charger Corporation. The Charger Corporation is an Illinois corporation controlled by James A. Bowen, Chief Executive Officer of First Trust. First Trust is responsible for supervising the selection and ongoing monitoring of the securities in the Fund’s portfolio, managing the Fund’s business affairs and providing certain administrative services necessary for the management of the Fund.
Pursuant to an investment management agreement between First Trust and the Trust, on behalf of the Fund (the “Investment Management Agreement”), First Trust oversees First Trust Capital Management L.P.’s (“First Trust Capital Management” or the “Sub-Advisor”) management of the Fund’s assets. First Trust is responsible for the expenses of the Fund including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, acquired fund fees and expenses, if any, brokerage commissions and other expenses connected with the execution of portfolio transactions, expenses associated with short sales transactions, distribution and service fees pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses. Effective November 1, 2022, the annual unitary management fee payable by the

Fund net assets greater than $7.5 billion up to and including $10 billion 1.15625%
Fund net assets greater than $10 billion 1.12500%
Prior to November 1, 2022, the Fund agreed to pay First Trust an annual unitary management fee equal to 1.25% of its average daily net assets. First Trust also provides fund reporting services to the Fund for a flat annual fee in the amount of $9,250, which is covered under the annual unitary management fee.
In connection with the introduction of the breakpoints discussed above, the Fund’s investment sub-advisory agreement has been amended to reflect that the investment sub-advisory fee paid to First Trust Capital Management L.P., the Fund’s investment sub-adviser, is based on First Trust’s management fee. Accordingly, during any period in which First Trust’s management fee is reduced in accordance with the breakpoints described above, the investment sub-advisory fee will be reduced to reflect the reduction in First Trust’s management fee.
First Trust Capital Partners, LLC, an affiliate of First Trust, owns a 50% ownership interest in First Trust Capital Management L.P. through First Trust Capital Solutions L.P.
The Trust has multiple service agreements with Brown Brothers Harriman & Co. (“BBH”). Under the service agreements, BBH performs custodial, fund accounting, certain administrative services, and transfer agency services for the Fund. As custodian, BBH is responsible for custody of the Fund’s assets. As fund accountant and administrator, BBH is responsible for maintaining the books and records of the Fund’s investments and cash. As transfer agent, BBH is responsible for maintaining shareholder records for the Fund.
Each Trustee who is not an officer or employee of First Trust, any sub-advisor or any of their affiliates (“Independent Trustees”) is paid a fixed annual retainer that is allocated equally among each fund in the First Trust Fund Complex. Each Independent Trustee is also paid an annual per fund fee that varies based on whether the fund is a closed-end or other actively managed fund, a target outcome fund or an index fund.
Additionally, the Lead Independent Trustee and the Chairs of the Audit Committee, Nominating and Governance Committee and Valuation Committee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Independent Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Lead Independent Trustee and Committee Chairs rotate every three years. The officers and “Interested” Trustee receive no compensation from the Trust for acting in such capacities.
4. Purchases and Sales of Securities
For the six months ended January 31, 2023, the cost of purchases and proceeds from sales of investments, excluding short term investments, investments sold short and in-kind transactions were $64,331,045 and $68,779,814, respectively. The cost of purchases to cover short sales and the proceeds of short sales were $11,427,234 and $11,291,589, respectively.
For the six months ended January 31, 2023, the cost of in-kind purchases and proceeds from in-kind sales were $28,051,836 and $5,152,946, respectively.
5. Creations, Redemptions and Transaction Fees
The Fund generally issues and redeems its shares in primary market transactions through a creation and redemption mechanism and does not sell or redeem individual shares. Instead, financial entities known as “Authorized Participants” have contractual arrangements with the Fund or one of the Fund’s service providers to purchase and redeem Fund shares directly with the Fund in large blocks of shares known as “Creation Units.” Prior to the start of trading on every business day, the Fund publishes through the National Securities Clearing Corporation (“NSCC”) the “basket” of securities, cash or other assets that it will accept in exchange for a Creation Unit of the Fund’s shares. An Authorized Participant that wishes to effectuate a creation of the Fund’s shares deposits with the Fund the “basket” of securities, cash or other assets identified by the Fund that day, and then receives the Creation Unit of the Fund’s shares in return for those assets. After purchasing a Creation Unit, the Authorized Participant may continue to hold the Fund’s shares or sell them in the secondary market. The redemption process is the reverse of the purchase process: the Authorized Participant redeems a
Page 16

Notes to Financial Statements (Continued)
First Trust Merger Arbitrage ETF (MARB)
January 31, 2023 (Unaudited)
Creation Unit of the Fund’s shares for a basket of securities, cash or other assets. The combination of the creation and redemption process with secondary market trading in the Fund’s shares and underlying securities provides arbitrage opportunities that are designed to help keep the market price of the Fund’s shares at or close to the NAV per share of the Fund.
The Fund imposes fees in connection with the purchase of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price for each Creation Unit will equal the daily NAV per share of the Fund times the number of shares in a Creation Unit, plus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the creation basket.
The Fund also imposes fees in connection with the redemption of Creation Units. These fees may vary based upon various fact-based circumstances, including, but not limited to, the composition of the securities included in the Creation Unit or the countries in which the transactions are settled. The price received for each Creation Unit will equal the daily NAV per share of the Fund times the number of shares in a Creation Unit, minus the fees described above and, if applicable, any operational processing and brokerage costs, transfer fees, stamp taxes and part or all of the spread between the expected bid and offer side of the market related to the securities comprising the redemption basket. Investors who use the services of a broker or other such intermediary in addition to an Authorized Participant to effect a redemption of a Creation Unit may also be assessed an amount to cover the cost of such services. The redemption fee charged by the Fund will comply with Rule 22c-2 of the 1940 Act which limits redemption fees to no more than 2% of the value of the shares redeemed.
6. Distribution Plan
The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. (“FTP”), the distributor of the Fund, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or to provide investor services. FTP may also use this amount to compensate securities dealers or other persons that are Authorized Participants for providing distribution assistance, including broker-dealer and shareholder support and educational and promotional services.
No 12b-1 fees are currently paid by the Fund, and pursuant to a contractual arrangement, no 12b-1 fees will be paid any time before November 30, 2023.
7. Indemnification
The Trust, on behalf of the Fund, has a variety of indemnification obligations under contracts with its service providers. The Trust’s maximum exposure under these arrangements is unknown. However, the Trust has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.
8. Subsequent Events
Management has evaluated the impact of all subsequent events to the Fund through the date the financial statements were issued and has determined that there were no subsequent events requiring recognition or disclosure in the financial statements that have not already been disclosed.

Risk Considerations
Risks are inherent in all investing. Certain general risks that may be applicable to a Fund are identified below, but not all of the material risks relevant to each Fund are included in this report and not all of the risks below apply to each Fund. The material risks of investing in each Fund are spelled out in its prospectus, statement of additional information and other regulatory filings. Before investing, you should consider each Fund’s investment objective, risks, charges and expenses, and read each Fund’s prospectus and statement of additional information carefully. You can download each Fund’s prospectus at www.ftportfolios.com or contact First Trust Portfolios L.P. at (800) 621-1675 to request a prospectus, which contains this and other information about each Fund.
Concentration Risk. To the extent that a fund is able to invest a significant percentage of its assets in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the fund’s investments more than if the fund were more broadly diversified. A fund that tracks an index will be concentrated to the extent the fund’s corresponding index is concentrated. A concentration makes a fund more susceptible to any single occurrence and may subject the fund to greater market risk than a fund that is more broadly diversified.
Credit Risk. Credit risk is the risk that an issuer of a security will be unable or unwilling to make dividend, interest and/or principal payments when due and the related risk that the value of a security may decline because of concerns about the issuer’s ability to make such payments.
Cyber Security Risk. The funds are susceptible to potential operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause a fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause a fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. In addition, cyber security breaches of a fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-advisor, as applicable, or issuers in which the fund invests, can also subject a fund to many of the same risks associated with direct cyber security breaches.
Defined Outcome Funds Risk. To the extent a fund’s investment strategy is designed to deliver returns tied to the price performance of an underlying ETF, an investor may not realize the returns the fund seeks to achieve if that investor does not hold shares for the entire target outcome period. In the event an investor purchases shares after the first day of the target outcome period or sells shares prior to the end of the target outcome period, the buffer that the fund seeks to provide against a decline in the value of the underlying ETF may not be available, the enhanced returns that the fund seeks to provide (if any) may not be available and the investor may not participate in a gain in the value of the underlying ETF up to the cap for the investor’s investment period. Additionally, the fund will not participate in gains of the underlying ETF above the cap and a shareholder may lose their entire investment. If the fund seeks enhanced returns, there are certain time periods when the value of the fund may fall faster than the value of the underlying ETF, and it is very unlikely that, on any given day during which the underlying ETF share price increases in value, the fund’s share price will increase at the same rate as the enhanced returns sought by the fund, which is designed for an entire target outcome period. Trading flexible exchange options involves risks different from, or possibly greater than, the risks associated with investing directly in securities, such as less liquidity and correlation and valuation risks. A fund may experience substantial downside from specific flexible exchange option positions and certain positions may expire worthless.
Derivatives Risk. To the extent a fund uses derivative instruments such as futures contracts, options contracts and swaps, the fund may experience losses because of adverse movements in the price or value of the underlying asset, index or rate, which may be magnified
Page 18

Additional Information (Continued)
First Trust Merger Arbitrage ETF (MARB)
January 31, 2023 (Unaudited)
by certain features of the derivative. These risks are heightened when a fund’s portfolio managers use derivatives to enhance the fund’s return or as a substitute for a position or security, rather than solely to hedge (or offset) the risk of a position or security held by the fund.
Equity Securities Risk. To the extent a fund invests in equity securities, the value of the fund’s shares will fluctuate with changes in the value of the equity securities. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant stock market, such as market volatility, or when political or economic events affecting the issuers occur. In addition, common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Equity securities may decline significantly in price over short or extended periods of time, and such declines may occur in the equity market as a whole, or they may occur in only a particular country, company, industry or sector of the market.
ETF Risk. The shares of an ETF trade like common stock and represent an interest in a portfolio of securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities, although lack of liquidity in an ETF could result in it being more volatile and ETFs have management fees that increase their costs. Shares of an ETF trade on an exchange at market prices rather than net asset value, which may cause the shares to trade at a price greater than net asset value (premium) or less than net asset value (discount). In times of market stress, decisions by market makers to reduce or step away from their role of providing a market for an ETF’s shares, or decisions by an ETF’s authorized participants that they are unable or unwilling to proceed with creation and/or redemption orders of an ETF’s shares, could result in shares of the ETF trading at a discount to net asset value and in greater than normal intraday bid-ask spreads.
Fixed Income Securities Risk. To the extent a fund invests in fixed income securities, the fund will be subject to credit risk, income risk, interest rate risk, liquidity risk and prepayment risk. Income risk is the risk that income from a fund’s fixed income investments could decline during periods of falling interest rates. Interest rate risk is the risk that the value of a fund’s fixed income securities will decline because of rising interest rates. Liquidity risk is the risk that a security cannot be purchased or sold at the time desired, or cannot be purchased or sold without adversely affecting the price. Prepayment risk is the risk that the securities will be redeemed or prepaid by the issuer, resulting in lower interest payments received by the fund. In addition to these risks, high yield securities, or “junk” bonds, are subject to greater market fluctuations and risk of loss than securities with higher ratings, and the market for high yield securities is generally smaller and less liquid than that for investment grade securities.
Index or Model Constituent Risk. Certain funds may be a constituent of one or more indices or ETF models. As a result, such a fund may be included in one or more index-tracking exchange-traded funds or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving a fund, the size of the fund and the market volatility of the fund. Inclusion in an index could increase demand for the fund and removal from an index could result in outsized selling activity in a relatively short period of time. As a result, a fund’s net asset value could be negatively impacted and the fund’s market price may be significantly below its net asset value during certain periods. In addition, index rebalances may potentially result in increased trading activity in a fund’s shares.
Index Provider Risk. To the extent a fund seeks to track an index, it is subject to Index Provider Risk. There is no assurance that the Index Provider will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, the Index Provider may carry out an unscheduled rebalance or other modification of the Index constituents or weightings, which may increase the fund’s costs. The Index Provider does not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and it does not guarantee that the Index will be calculated in accordance with its stated methodology. Losses or costs associated with any Index Provider errors generally will be borne by the fund and its shareholders.
Investment Companies Risk. To the extent a fund invests in the securities of other investment vehicles, the fund will incur additional fees and expenses that would not be present in a direct investment in those investment vehicles. Furthermore, the fund’s investment performance and risks are directly related to the investment performance and risks of the investment vehicles in which the fund invests.
LIBOR Risk. To the extent a fund invests in floating or variable rate obligations that use the London Interbank Offered Rate (“LIBOR”) as a reference interest rate, it is subject to LIBOR Risk. The United Kingdom’s Financial Conduct Authority, which regulates LIBOR has ceased making LIBOR available as a reference rate over a phase-out period that began December 31, 2021. There is no assurance that any alternative reference rate, including the Secured Overnight Financing Rate (“SOFR”) will be similar to or produce the same value or economic equivalence as LIBOR or that instruments using an alternative rate will have the same volume or liquidity. The unavailability or replacement of LIBOR may affect the value, liquidity or return on certain fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any potential effects of the transition away from LIBOR on the fund or on certain instruments in which the fund invests can be difficult to ascertain, and they may vary depending on a variety of factors, and they could result in losses to the fund.

Management Risk. To the extent that a fund is actively managed, it is subject to management risk. In managing an actively-managed fund’s investment portfolio, the fund’s portfolio managers will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that a fund will meet its investment objective.
Market Risk. Market risk is the risk that a particular security, or shares of a fund in general, may fall in value. Securities held by a fund, as well as shares of a fund itself, are subject to market fluctuations caused by factors such as general economic conditions, political events, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of a fund could decline in value or underperform other investments as a result of the risk of loss associated with these market fluctuations. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on a fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. In February 2022, Russia invaded Ukraine which has caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, and the United States. The hostilities and sanctions resulting from those hostilities could have a significant impact on certain fund investments as well as fund performance. The COVID-19 global pandemic and the ensuing policies enacted by governments and central banks have caused and may continue to cause significant volatility and uncertainty in global financial markets. While the U.S. has resumed “reasonably” normal business activity, many countries continue to impose lockdown measures. Additionally, there is no guarantee that vaccines will be effective against emerging variants of the disease. These events also adversely affect the prices and liquidity of a fund’s portfolio securities or other instruments and could result in disruptions in the trading markets. Any of such circumstances could have a materially negative impact on the value of a fund’s shares and result in increased market volatility. During any such events, a fund’s shares may trade at increased premiums or discounts to their net asset value and the bid/ask spread on a fund’s shares may widen.
Non-U.S. Securities Risk. To the extent a fund invests in non-U.S. securities, it is subject to additional risks not associated with securities of domestic issuers. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to: possible adverse political, social or economic developments; restrictions on foreign investment or exchange of securities; capital controls; lack of liquidity; currency exchange rates; excessive taxation; government seizure of assets; the imposition of sanctions by foreign governments; different legal or accounting standards; and less government supervision and regulation of exchanges in foreign countries. Investments in non-U.S. securities may involve higher costs than investments in U.S. securities, including higher transaction and custody costs, as well as additional taxes imposed by non-U.S. governments. These risks may be heightened for securities of companies located, or with significant operations, in emerging market countries.
Operational Risk. Each fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of a fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. Each fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect a fund’s ability to meet its investment objective. Although the funds and the funds’ investment advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.
Passive Investment Risk. To the extent a fund seeks to track an index, the fund will invest in the securities included in, or representative of, the index regardless of their investment merit. A fund generally will not attempt to take defensive positions in declining markets.
Preferred Securities Risk. Preferred securities combine some of the characteristics of both common stocks and bonds. Preferred securities are typically subordinated to bonds and other debt securities in a company’s capital structure in terms of priority to corporate income, subjecting them to greater credit risk than those debt securities. Generally, holders of preferred securities have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may obtain limited rights. In certain circumstances, an issuer of preferred securities may defer payment on the securities and, in some cases, redeem the securities prior to a specified date. Preferred securities may also be substantially less liquid than other securities, including common stock.
Valuation Risk. The valuation of certain securities may carry more risk than that of common stock. Uncertainties in the conditions of the financial markets, unreliable reference data, lack of transparency and inconsistency of valuation models and processes may lead to inaccurate asset pricing. A fund may hold investments in sizes smaller than institutionally sized round lot positions (sometimes referred to as odd lots). However, third-party pricing services generally provide evaluations on the basis of institutionally-sized round lots. If a fund sells certain of its investments in an odd lot transaction, the sale price may be less than the value at which such securities
Page 20

January 31, 2023 (Unaudited)
have been held by the fund. Odd lots often trade at lower prices than institutional round lots. There is no assurance that the fund will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to the fund.

Advisory and Sub-Advisory Agreements
Board Considerations Regarding Approval of Amendments to the Investment Management and Investment Sub-Advisory Agreements
The Board of Trustees of First Trust Exchange-Traded Fund III (the “Trust”), including the Independent Trustees, unanimously approved the amendment (the “Advisory Agreement Amendment”) of the Investment Management Agreement (the “Advisory Agreement”) with First Trust Advisors L.P. (the “Advisor”) and the amendment (the “Sub-Advisory Agreement Amendment” and together with the Advisory Agreement Amendment, the “Amendments”) of the Investment Sub-Advisory Agreement (the “Sub-Advisory Agreement” and together with the Advisory Agreement, the “Agreements”) among the Trust, the Advisor and First Trust Capital Management L.P. (the “Sub-Advisor”) on behalf of the First Trust Merger Arbitrage ETF (the “Fund”).
The Board approved the Amendments at a meeting held on October 24, 2022. As part of the review process, the Board reviewed information and had preliminary discussions with the Advisor regarding the proposed Amendments at meetings held on April 18, 2022, June 12–13, 2022 and September 18–19, 2022. Following those preliminary discussions, the Board requested and received information from the Advisor regarding the proposed Amendments, and that information was considered at an executive session of the Independent Trustees and their counsel held prior to the October 24, 2022 meeting, as well as at the October meeting.
In reviewing the Advisory Agreement Amendment, the Board considered that the purpose of the Advisory Agreement Amendment is to modify the unitary fee rate for the Fund under the Advisory Agreement by introducing a breakpoint schedule pursuant to which the unitary fee rate paid by the Fund to the Advisor will be reduced as assets of the Fund meet certain thresholds. In reviewing the Sub-Advisory Agreement Amendment, the Board considered that the purpose of the Sub-Advisory Agreement Amendment is to modify the sub-advisory fee rate for the Fund under the Sub-Advisory Agreement to reflect the modification of the unitary fee rate schedule under the Advisory Agreement Amendment. The Board noted the Advisor’s representations that the quality and quantity of the services provided to the Fund by the Advisor under the Advisory Agreement and by the Sub-Advisor under the Sub-Advisory Agreement will not be reduced or modified as a result of the Advisory Agreement Amendment and the Sub-Advisory Agreement Amendment, and that the obligations of the Advisor under the Advisory Agreement and the obligations of the Sub-Advisor under the Sub-Advisory Agreement will remain the same in all respects.
The Board noted that it, including the Independent Trustees, last approved the continuation of the Advisory Agreement for a one-year period ending June 30, 2023 at a meeting held on June 12–13, 2022. The Board noted that in connection with such approval it had determined, based upon the information provided, that the terms of the Advisory Agreement were fair and reasonable and that the continuation of the Advisory Agreement was in the best interests of the Fund in light of the nature, extent and quality of the services provided and such other matters as the Board considered to be relevant in the exercise of its business judgment.
The Board also noted that it, including the Independent Trustees, approved the Sub-Advisory Agreement for an initial two-year period ending February 22, 2024 at a meeting held on September 12–13, 2021 and that shareholders of the Fund approved the Sub-Advisory Agreement at a meeting held on February 22, 2022. The Board noted that in connection with its approval it had determined, based upon the information provided, that the terms of the Sub-Advisory Agreement were fair and reasonable and that the approval of the Sub-Advisory Agreement was in the best interests of the Fund in light of the nature, extent and quality of the services provided and such other matters as the Board considered to be relevant in the exercise of its business judgment.
Based on all of the information considered, the Board, including the Independent Trustees, unanimously determined that the terms of the Amendments are fair and reasonable and that the Amendments are in the best interests of the Fund.
