("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 AlphaDEX(R) Fund (the "Trust") described in this report (each such series is referred to as a "Fund" and collectively, as the "Funds") to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. When evaluating the information included in this report, you are cautioned not to place undue reliance on these forward-looking statements, which reflect the judgment of the Advisor and its representatives only as of the date hereof. 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 shares may therefore be less than what you paid for them. Accordingly, you can lose money investing in a Fund. See "Risk Considerations" in the Additional Information section of this report for a discussion of 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 http://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 webpage at http://www.ftportfolios.com HOW TO READ THIS REPORT This This report contains information that may help you evaluate your investment in each Fund.

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the annual report which contains detailed information about your investment for the 12 months ended July 31, 2016, including a market overview and a performance analysis for the period. We encourage you to read this report and discuss it with your financial advisor. While markets were up and down during 2015, we believe there are three important things to remember. First, the U.S. economy grew, despite the massive decline in oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the "Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated rate hike by the Fed in December 2015 had little effect on the money supply, and the stock market was not shocked by the hike. Early in 2016, many investors were concerned that the volatility we saw in the market in 2015 would continue, and it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index declined by 10.27%. Since then, the market has made a steady comeback, and from February 11, 2016 to July 31, 2016, the S&P 500(R) Index was up 19.99%. First Trust believes that having a long-term investment horizon and investing in quality products can help you reach your goals, regardless of how the market behaves. We have always maintained perspective about the markets and believe investors should as well. We will continue to strive to provide quality investment opportunities each and every day, which has been one of the hallmarks of our firm since its inception 25 years ago. Thank you for giving First Trust the opportunity to be a part of your investment plan. We value our relationship with you and will continue to focus on helping investors like you reach your financial goals. Sincerely, /s/ James A. Bowen James A. Bowen Chairman of the Board of Trustees Chief Executive Officer of First Trust Advisors L.P. Page 2 -------------------------------------------------------------------------------- MARKET OVERVIEW -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND ANNUAL REPORT JULY 31, 2016 ROBERT F. CAREY, CFA SENIOR VICE PRESIDENT AND CHIEF MARKET STRATEGIST FIRST TRUST ADVISORS L.P. Mr. Carey is responsible for the overall management of research and analysis of the First Trust product line. Mr. Carey has over 25 years of experience as an Equity and Fixed-Income Analyst and is a recipient of the Chartered Financial Analyst ("CFA") designation. He is a graduate of the University of Illinois at Champaign-Urbana with a B.S. in Physics. He is also a member of the Investment Analysts Society of Chicago and the CFA Institute. Mr. Carey has appeared as a guest on such programs as Bloomberg TV, CNBC, and WBBM Radio, and has been quoted by several publications, including The Wall Street Journal, The Wall Street Reporter, Bloomberg News Service, and Registered Rep. STATE OF THE U.S. ECONOMY One of the reasons cited by the Federal Reserve for not raising interest rates beyond the initial 0.25% hike in the federal funds target rate on December 16, 2015 is the slowdown in global growth. The International Monetary Fund reduced its global growth estimate for 2016 from 3.3% in April to 3.2% in July. It also shaved its 2017 estimate by 0.1% to 3.5%, according to its own release. To help put this concern into perspective, the rate was 5.4% in 2010. The rebound in the price of crude oil is boosting Mergers & Acquisitions ("M&A") activity in the energy sector, according to Bloomberg. From February 11, 2016 (multi-year low) through August 25, 2016, the price of a barrel of crude oil rose 80.6%, from $26.21 to $47.33. Wood Mackenzie, a consulting firm, reported that more than $11 billion worth of oil and gas transactions were announced globally in July. It was the highest monthly total so far this year. Since May, deal volume has totaled $32 billion. Wood Mackenzie believes that M&A activity will continue to accelerate as oil prices stabilize. Higher energy prices, if sustained, could help boost global economic growth moving forward. Many nations around the globe rely fairly heavily on the sale of crude oil to help fund their economies, in our opinion. ETFGI, an industry research group, reported that total assets invested in exchange-traded funds (ETFs) and other exchange-traded products (ETPs) reached a record high of $3.34 trillion globally in July 2016, according to its own release. Total assets invested in U.S. ETFs/ETPs reached a record high of $2.37 trillion in July 2016. SECTOR INVESTING One barometer for gauging investors' appetites for equities is tracking money flows in and out of open-end mutual funds and ETFs. For the 12-month period ended July 31, 2016, U.S. Equity funds/ETFs reported net outflows totaling over $47 billion, according to data from Morningstar. Investors continue to favor passive funds over actively managed funds. Passive U.S. Equity funds/ETFs reported net inflows totaling $163.6 billion, compared to net outflows totaling $211.0 billion for actively managed U.S. Equity funds/ETFs. For the 12-month period ended July 2016, investors pulled capital from sector funds/ETFs, which reported net outflows totaling $18.1 billion. Passive Sector Equity funds/ETFs reported net inflows totaling $3.1 billion, compared to net outflows totaling $21.2 billion for actively managed Sector Equity funds/ETFs. Using Morningstar fund categories, some of the major sectors reporting the highest net inflows over the past 12 months were Real Estate ($7.3 billion), Equity Energy ($5.6 billion), Utilities ($2.8 billion), Consumer Defensive ($2.3 billion) and Communications ($1.3 billion). Slow and steady appears to be winning the race, in our opinion. Despite the moderate pace of economic growth since the previous recession ended in 2009, the current bull market in stocks is the second-longest in U.S. history at 2,701 days through July, as measured by the S&P 500(R) Index, according to Bespoke Investment Group. From March 9, 2009 to July 29, 2016, the S&P 500(R) Index posted a cumulative total return of 275.51%, according Bloomberg. From 2009 to 2015, the S&P 500(R) Index increased its annual earnings from $58.15 to $109.32, according to Bloomberg. As of August 5, 2016, Bloomberg's consensus estimates for 2016 and 2017 are $117.73 and $133.11, respectively.

The Fund will normally invest at least 90% of its net assets in common stocks that comprise the Consumer Discretionary Index. The shares of the Fund are listed and trade on the NYSE Arca, Inc. (the "NYSE Arca" or the "Exchange") under the ticker symbol "FXD." The Consumer Discretionary Index is a modified equal-dollar weighted index designed by NYSE Group, Inc. or its affiliates ("NYSE") to objectively identify and select stocks from the Russell 1000(R) Index in the consumer discretionary sector that may generate positive alpha relative to traditional passive-style indices through the use of the AlphaDEX(R) screening methodology. Alpha is an indication of how much an investment outperforms or underperforms on a risk-adjusted basis relative to its benchmark. The NYSE constructs the Consumer Discretionary Index using the Russell Global Sectors (the "RGS") sector scheme to determine a stock's sector membership.

(See Notes to Fund Performance Overview on page 22.) PERFORMANCE REVIEW FXD's one-year net asset value ("NAV") return of -2.34% underperformed the benchmark S&P 500(R) Consumer Discretionary Index return of 3.53% by -5.87%. The Auto Components industry was the best contributing and best performing industry during the period, with a 0.97% contribution and 17.4% return. The Textiles Apparel & Luxury Goods industry was the worst contributing and second worst performing industry during the period, with a -1.7% contribution and -17.1% return. The highest weighted industry during the period was Specialty Retail at an average 23.2% weighting. This industry had an average return of -0.7%. On a relative basis, the Fund underperformed the benchmark primarily because the Fund was underweight Amazon.com, Inc. within the Internet & Catalog Retail industry. Amazon.com, Inc. was held at an average weighting of 1.3% during the period versus the benchmark weighting of 10.4%. Amazon.com, Inc.'s return of 41.5% caused -2.9% of relative underperformance. The Fund's underweighting of Walt Disney Co. by 6.5%, relative to the benchmark, reversed 1.6% of underperformance. Walt Disney Co. had a return of -18.6% during the period. ---------------------------------------------------------- % OF TOTAL SECTOR CLASSIFICATION LONG-TERM INVESTMENTS ---------------------------------------------------------- Consumer Discretionary 92.37% Industrials 3.57 Information Technology 1.44 Consumer Staples 1.33 Financials 1.29 ------- Total 100.00% ======= ---------------------------------------------------------- % OF TOTAL TOP TEN HOLDINGS LONG-TERM INVESTMENTS ---------------------------------------------------------- Penske Automotive Group, Inc. 1.64% Gap (The), Inc. 1.58 GameStop Corp., Class A 1.51 Burlington Stores, Inc. 1.49 Gentex Corp. 1.49 BorgWarner, Inc. 1.46 Dillard's, Inc., Class A 1.45 Lear Corp. 1.45 General Motors Co. 1.45 Best Buy Co., Inc. 1.43 ------- Total 14.95% ======= ----------------------------- (1) On or about September 18, 2008, Russell Investment Group ("Russell") began calculating its Russell U.S. Indices using an enhanced Russell sector scheme, the RGS. The RGS and the former U.S. sector scheme ran in tandem until June 30, 2009, when Russell officially transitioned to the RGS and ceased calculating its indices using the U.S. sector scheme. In addition to the implementation of the RGS, Russell changed the name of the Russell 1000(R) Consumer Discretionary and Services Index to the Russell 1000(R) Consumer Discretionary Index. Consequently, performance data is not available for all the periods shown in the table for the Russell 1000(R) Consumer Discretionary Index because performance data does not exist for each of the entire periods using solely the U.S. sector scheme, or alternatively, using solely the RGS.

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. FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2016 The following Frequency Distribution of Discounts and Premiums charts are provided to show the frequency at which the bid/ask midpoint price for the Fund was at a discount or premium to the daily NAV. The following tables are for comparative purposes only and represent the period August 1, 2011 through July 31, 2016. Shareholders may pay more than NAV when they buy Fund shares and receive less than NAV when they sell those shares because shares are bought and sold at current market price.

(See Notes to Fund Performance Overview on page 22.) PERFORMANCE REVIEW FXG's one-year NAV return of 9.19% underperformed the benchmark S&P 500(R) Consumer Staples Index return of 11.67% by -2.48%. With a return of 7.8% and average weighting of 44.9%, Food Products was the top performing and highest weighted industry during the period, contributing 7.8% to the Fund's return. Within the industry, Tyson Foods, Inc. was the top returning security with a 67.6% return. The Food & Staples Retailing was the only industry to have a negative return during the period, with a -9.6% return. The Fund held this industry at an average 21.9% weighting, leading to a contribution of -2.0% during the period. Rite Aid Corp. was the worst performing security with a -21.4% return. On a relative basis, the Fund underperformed the benchmark primarily due to the Fund overweighting Rite Aid Corp. by 3.8%, creating -1.5% of drag, and due to the Fund underweighting the Tobacco industry by 9.7%, creating -1.2% of drag. The Tobacco industry had a return of 22.7% during the period. The well-performing Food Products industry reversed 2.3% of drag by being overweight 27.8% in the well performing industry. Tyson Foods, Inc., as mentioned above, created 1.8% of relative outperformance. ---------------------------------------------------------- % OF TOTAL SECTOR CLASSIFICATION LONG-TERM INVESTMENTS ---------------------------------------------------------- Consumer Staples 100.00% ------- Total 100.00% ======= ---------------------------------------------------------- % OF TOTAL TOP TEN HOLDINGS LONG-TERM INVESTMENTS ---------------------------------------------------------- Spectrum Brands Holdings, Inc. 5.08% Post Holdings, Inc. 4.93 Ingredion, Inc. 4.84 Sysco Corp. 4.80 TreeHouse Foods, Inc. 4.73 Energizer Holdings, Inc. 4.71 Mondelez International, Inc., Class A 4.55 WhiteWave Foods (The) Co. 3.89 Bunge Ltd. 3.67 Tyson Foods, Inc., Class A 3.63 ------- Total 44.83% ======= ----------------------------- (1) On or about September 18, 2008, Russell began calculating its Russell U.S. Indices using an enhanced Russell sector scheme, the RGS.

(See Notes to Fund Performance Overview on page 22.) PERFORMANCE REVIEW FXN's one-year NAV return of -12.67% underperformed the benchmark S&P 500(R) Energy Index return of 2.03% by -14.70%. The Energy Equipment & Services and Oil Gas & Consumable Fuels industries each contributed about -5.75% during the period. California Resources Corp. stands out as the worst performing security with a -69.6% return during the period, contributing -2.3% to the Fund's return. Exxon Mobil Corp. and Chevron Co., the two largest energy conglomerates held within the Fund, posted solid returns of 16.4% and 21.5%, respectively, during the period. On a relative basis, the Fund underperformed the benchmark. Exxon Mobil Corp. and Chevron Co. were two of the leading contributors to the underperformance as the Fund was underweight the benchmark -25.4% and -11.3%, respectively, causing in total -5.1% of relative underperformance. Because the benchmark is market cap weighted, these two securities take the lion's share of the weighting at 41.6%. The Fund reversed 1.7% of the relative underperformance by holding Kinder Morgan, Inc., which returned -38.9% during the period, at a 2% smaller weighting. ---------------------------------------------------------- % OF TOTAL SECTOR CLASSIFICATION LONG-TERM INVESTMENTS ---------------------------------------------------------- Energy 96.71% Information Technology 3.29 ------- Total 100.00% ======= ---------------------------------------------------------- % OF TOTAL TOP TEN HOLDINGS LONG-TERM INVESTMENTS ---------------------------------------------------------- HollyFrontier Corp. 3.65% Marathon Petroleum Corp. 3.54 Valero Energy Corp. 3.50 Tesoro Corp. 3.47 Antero Resources Corp. 3.44 First Solar, Inc. 3.29 Phillips 66 3.27 Dril-Quip, Inc. 3.18 Transocean Ltd. 3.15 Noble Corp.

(See Notes to Fund Performance Overview on page 22.) PERFORMANCE REVIEW FXO's one-year NAV return of 0.22% outperformed the benchmark S&P 500(R) Financials Index return of -3.77% by 3.99%. It was the Real Estate Investment Trust ("REIT") industry that contributed the most to the Fund's return during the period. This industry had a return of 19.9%, an average weighting of 20.8%, and contribution of 4.4%. Digital Realty Trust, Inc. also stood out as the top performing security within the REIT industry with a 69.9% return. The Capital Market industry was the worst contributing industry with a -2.2% contribution. Notably, Waddell & Reed Financial, Inc. returned -60.9% during the period creating -0.8% contribution. On a relative basis, the Fund outperformed the benchmark primarily due to the Fund's holdings within the Banking industry. The Fund underweighted this poor performing industry (-10.3% return) by 18.6%, creating 2.5% of relative outperformance. Amongst the Diversified Financial Services industry, the Fund lost -1.2% of relative performance by having a 7.4% lower allocation and -7.3% lower return. ---------------------------------------------------------- % OF TOTAL SECTOR CLASSIFICATION LONG-TERM INVESTMENTS ---------------------------------------------------------- Financials 90.27% Information Technology 6.55 Industrials 2.61 Consumer Discretionary 0.57 ------- Total 100.00% ======= ---------------------------------------------------------- % OF TOTAL TOP TEN HOLDINGS LONG-TERM INVESTMENTS ---------------------------------------------------------- Lazard Ltd., Class A 1.10% Popular, Inc. 1.05 Jones Lang LaSalle, Inc. 1.03 MarketAxess Holdings, Inc. 1.01 Franklin Resources, Inc. 0.99 CIT Group, Inc. 0.99 Fidelity National Information Services, Inc. 0.99 Fifth Third Bancorp 0.99 Senior Housing Properties Trust 0.97 Santander Consumer USA Holdings, Inc. 0.97 ------- Total 10.09% ======= ----------------------------- (1) On or about September 18, 2008, Russell began calculating its Russell U.S. Indices using an enhanced Russell sector scheme, the RGS.

(See Notes to Fund Performance Overview on page 22.) PERFORMANCE REVIEW FXL's one-year NAV return of 0.42% underperformed the benchmark S&P 500(R) Information Technology Index return of 9.77% by -9.35%. The Fund saw the majority of its positive return from the Electronic Equipment Instruments & Components Industry and Semiconductors & Semiconductor Equipment industry, which contributed 2.6% and 2.7%, respectively. NVIDIA Corp., held within the Semiconductors & Semiconductor Equipment industry, stood out as the top performing security in the Fund with a 190.3% return. The Communications Equipment industry lagged with a return of -16.0% and -2.1% contribution. Within this industry, Arista Networks, Inc. had a return of -33.5% and -0.8% contribution to the Fund's return. On a relative basis, the Fund underperformed the benchmark. The Software industry was the leading cause of the underperformance. The Fund held this industry at an average weighting of 23.7%, 3% higher than the benchmark, and had a return 0.5%, 17.1% lower than the benchmark. Microsoft Co.'s 10.1% lower weighting and -11.6% worse relative return caused -1.3% of the underperformance. Several other securities within the Software industry contributed to an additional -3.3% of drag. Apple, Inc., held within the Technology Hardware Storage & Peripherals industry, reversed 3.7% of relative underperformance from holding the -12.3% returning security at a 15.5% lower weighting. ---------------------------------------------------------- % OF TOTAL SECTOR CLASSIFICATION LONG-TERM INVESTMENTS ---------------------------------------------------------- Information Technology 99.16% Health Care 0.44 Telecommunication Services 0.40 ------- Total 100.00% ======= ---------------------------------------------------------- % OF TOTAL TOP TEN HOLDINGS LONG-TERM INVESTMENTS ---------------------------------------------------------- NVIDIA Corp. 2.40% ON Semiconductor Corp. 2.25 Jabil Circuit, Inc. 2.18 Applied Materials, Inc. 2.17 Apple, Inc. 2.15 Arrow Electronics, Inc. 2.12 Cisco Systems, Inc. 2.10 Intel Corp. 2.10 Skyworks Solutions, Inc. 2.06 Avnet, Inc. 2.00 ------- Total 21.53% ======= ----------------------------- (1) On or about September 18, 2008, Russell began calculating its Russell U.S. Indices using an enhanced Russell sector scheme, the RGS.

(See Notes to Fund Performance Overview on page 22.) PERFORMANCE REVIEW FXU's one-year NAV return of 22.66% underperformed the benchmark S&P 500(R) Utilities Index return of 23.10% by -0.44%. Electric Utilities, with the greatest allocation of 42.6%, was the top contributing industry with a 10.5% contribution. The top performing industry, Gas Utilities, had a 48.8% return, but only contributed 2.9% due to its lower allocation of 5.3% during the period. The Independent Power & Renewable Electricity Producers industry, with an allocation of 7.4% during the period, returned -25.5% and contributed -3.1% to the Fund's return. On a relative basis, the Fund underperformed the benchmark. The Independent Power & Renewable Electricity Producers industry accounted for -3.6% of the underperformance due to having a 5.3% greater allocation and -8.9% worse performance. Calpine Corp. accounted for -2.1% of the drag by the Fund having a 3.4% greater allocation than the benchmark in the -24.9% returning security. The Multi-Utilities industry reversed 1.8% of underperformance by having a 6.5% higher return than the benchmark during the period. SCANA Corp., within this industry, was the cause of 0.5% relative outperformance due to the Fund having a 2.5% greater allocation to the 41.8% returning security. ---------------------------------------------------------- % OF TOTAL SECTOR CLASSIFICATION LONG-TERM INVESTMENTS ---------------------------------------------------------- Utilities 63.33% Telecommunication Services 36.67 ------- Total 100.00% ======= ---------------------------------------------------------- % OF TOTAL TOP TEN HOLDINGS LONG-TERM INVESTMENTS ---------------------------------------------------------- Sprint Corp. 4.45% CenturyLink, Inc. 4.45 T-Mobile US, Inc. 4.40 Telephone and Data Systems, Inc. 4.36 AT&T, Inc. 4.11 FirstEnergy Corp. 4.11 Verizon Communications, Inc. 4.07 Public Service Enterprise Group, Inc. 4.05 Level 3 Communications, Inc. 4.03 Frontier Communications Corp. 3.46 ------- Total 41.49% ======= ----------------------------- (1) On or about September 18, 2008, Russell began calculating its Russell U.S. Indices using an enhanced Russell sector scheme, the RGS.

"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 and expenses reimbursed 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 between the highest bid and the lowest offer on the stock exchange on which shares of the Fund are listed for trading as of the time that the Fund's NAV is calculated. Since shares of each Fund did not trade in the secondary market until after the Fund's inception, for the period May 8, 2007 (inception) to May 10, 2007 (the first day of secondary market trading) 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. Page 22 FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS UNDERSTANDING YOUR FUND EXPENSES JULY 31, 2016 As a shareholder of First Trust Consumer Discretionary AlphaDEX(R) Fund, First Trust Consumer Staples AlphaDEX(R) Fund, First Trust Energy AlphaDEX(R) Fund, First Trust Financials AlphaDEX(R) Fund, First Trust Health Care AlphaDEX(R) Fund, First Trust Industrials/Producer Durables AlphaDEX(R) Fund, First Trust Materials AlphaDEX(R) Fund, First Trust Technology AlphaDEX(R) Fund or First Trust Utilities AlphaDEX(R) Fund (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 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 July 31, 2016. 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 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 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.

ORGANIZATION First Trust Exchange-Traded AlphaDEX(R) Fund (the "Trust") is an open-end management investment company organized as a Massachusetts business trust on December 6, 2006, 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 twenty-one exchange-traded funds considered either a Sector Fund or a Style Fund. This report covers the nine Sector Funds listed below. The shares of each Sector Fund are listed and traded on NYSE Arca, Inc. First Trust Consumer Discretionary AlphaDEX(R) Fund - (ticker "FXD") First Trust Consumer Staples AlphaDEX(R) Fund - (ticker "FXG") First Trust Energy AlphaDEX(R) Fund - (ticker "FXN") First Trust Financials AlphaDEX(R) Fund - (ticker "FXO") First Trust Health Care AlphaDEX(R) Fund - (ticker "FXH") First Trust Industrials/Producer Durables AlphaDEX(R) Fund - (ticker "FXR") First Trust Materials AlphaDEX(R) Fund - (ticker "FXZ") First Trust Technology AlphaDEX(R) Fund - (ticker "FXL") First Trust Utilities AlphaDEX(R) Fund - (ticker "FXU") Each fund represents a separate series of shares of beneficial interest in the Trust (each a "Fund" and collectively, the "Funds"). Unlike conventional mutual funds, each Fund issues and redeems shares on a continuous basis, at net asset value ("NAV"), only in large specified blocks consisting of 50,000 shares called a "Creation Unit." Creation Units are issued and redeemed principally in-kind for securities included in a Fund's relevant index. Except when aggregated in Creation Units, each Fund's shares are not redeemable securities. The investment objective of each Fund is to seek investment results that correspond generally to the price and yield (before the Fund's fees and expenses) of the following indices:

("FTP"), the distributor of the Trust, by Archipelago Holdings, Inc. ("Archipelago"), an affiliate of NYSE Group. Prior to the acquisition of the American Stock Exchange LLC (the "AMEX") by NYSE Group, the index was developed, maintained and sponsored by AMEX. 2. SIGNIFICANT ACCOUNTING POLICIES The Funds, each of which is an investment company within the scope of Financial Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follow accounting and reporting guidance under FASB 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 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 adopted by the Trust's Board of Page 61 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2016 Trustees, and in accordance with provisions of the 1940 Act. 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 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 principal market for such securities. Shares of open-end funds are valued at fair value which is based on NAV per share. Securities traded in an over-the-counter market are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price. Overnight repurchase agreements are valued at amortized cost when it represents the best estimate of fair value. Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Trust's Board of Trustees or its delegate, 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 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 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 type of security; 2) the size of the holding; 3) the initial cost of the security; 4) transactions in comparable securities; 5) price quotes from dealers and/or pricing services; 6) relationships among various securities; 7) information obtained by contacting the issuer, analysts, or the appropriate stock exchange; 8) an analysis of the issuer's financial statements; and 9) the existence of merger proposals or tender offers that might affect the value of the security. In addition, differences between the prices used to calculate a Fund's NAV and the prices used by such Fund's corresponding index could result in a difference between a Fund's performance and the performance of its underlying index. 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: o 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. o 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. o 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. Page 62 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2016 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 July 31, 2016, 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 on the accrual basis. Distributions received from a 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 is 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. OFFSETTING ON THE STATEMENTS OF ASSETS AND LIABILITIES Offsetting Assets and Liabilities require entities to disclose both gross and net information about instruments and transactions eligible for offset on the Statements of Assets and Liabilities, and disclose instruments and transactions subject to master netting or similar agreements. These disclosure requirements are intended to help investors and other financial statement users better assess the effect or potential effect of offsetting arrangements on a fund's financial position. The transactions subject to offsetting disclosures are derivative instruments, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions. This disclosure, if applicable, is included within each Fund's Portfolio of Investments under the heading "Offsetting Assets and Liabilities." For financial reporting purposes, the Funds do not offset financial assets and financial liabilities that are subject to master netting arrangements ("MNAs") or similar agreements on the Statements of Assets and Liabilities. MNAs provide the right, in the event of default (including bankruptcy and insolvency), for the non-defaulting counterparty to liquidate the collateral and calculate the net exposure to the defaulting party or request additional collateral. D. SECURITIES LENDING The Funds may lend securities representing up to 33 1/3% of the value of their total assets to broker-dealers, banks and other institutions to generate additional income. When a Fund loans its portfolio securities, it will receive, at the inception of each loan, collateral equal to at least 102% (for domestic securities) or 105% (for international securities) of the market value of the loaned securities. The collateral amount is valued at the beginning of each business day and is compared to the market value of the loaned securities from the prior business day to determine if additional collateral is required. If additional collateral is required, a request is sent to the borrower. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund's loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of (i) a decline in the value of the collateral provided for the loaned securities, (ii) a decline in the value of any investments made with cash collateral or (iii) an increase in the value of the loaned securities if the borrower does not increase the collateral accordingly and the borrower fails to return the securities. These events could also trigger adverse tax consequences for the Funds. Under the Funds' Securities Lending Agency Agreement, the securities lending agent will generally bear the risk that a borrower may default on its obligation to return loaned securities. Brown Brothers Harriman & Co. ("BBH") acts as the Funds' securities lending agent and is responsible for executing the lending of the portfolio securities to creditworthy borrowers. The Funds, however, will be responsible for the risks associated with the investment of cash collateral. A Fund may lose money on its investment of cash collateral, which may affect its ability to repay the collateral to the borrower without the use of other Fund assets. Each Fund that engages in securities lending receives compensation (net of any rebate and securities lending agent fees) for lending its securities. Compensation can be in the form of fees received from the securities lending agent or dividends or interest earned from the investment of cash collateral. The dividend and interest earned on the securities loaned is accounted for in the same manner as other dividend and interest income. At July 31, 2016, all the Funds except FXH, FXR and FXZ have securities in the securities lending program. During the fiscal year ended July 31, 2016, all the Funds participated in the securities lending program. In the event of a default by a borrower with respect to any loan, BBH will exercise any and all remedies provided under the applicable borrower agreement to make the Funds whole. These remedies include purchasing replacement securities by applying the collateral held from the defaulting broker against the purchase cost of the replacement securities. If, despite such efforts by BBH to exercise these remedies, a Funds sustains losses as a result of a borrower's default, BBH will indemnify the Fund by purchasing replacement securities at its own expense, or paying the Fund an amount equal to the market value of the replacement securities, subject to certain limitations which are set forth in detail in the Securities Lending Agency Agreement between the Trust on behalf of the Funds and BBH. Page 63 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2016 E. REPURCHASE AGREEMENTS Repurchase agreements involve the purchase of securities subject to the seller's agreement to repurchase the securities at a mutually agreed upon date and price, under the terms of a Master Repurchase Agreement ("MRA"). During the term of a repurchase agreement, the value of the underlying securities held as collateral on behalf of a Fund, including accrued interest, is required to exceed the value of the repurchase agreement, including accrued interest. The underlying securities for all repurchase agreements are held at the Funds' custodian or designated sub-custodians under tri-party repurchase agreements. MRAs govern transactions between a Fund and select counterparties. The MRAs maintain provisions for, among other things, initiation, income payments, events of default, and maintenance of collateral for repurchase agreements. Repurchase agreements received for lending securities are collateralized by U.S. Treasury Notes. The U.S. Treasury Notes are held in a joint custody account at BBH on behalf of the Funds participating in the securities lending program. In the event the counterparty defaults on the repurchase agreement, the U.S. Treasury Notes can either be maintained as part of a Fund's portfolio or sold for cash. A Fund could suffer a loss to the extent that the proceeds from the sale of the underlying collateral held by the Fund is less than the repurchase price and the Fund's costs associated with the delay and enforcement of the MRA. While the Funds may invest in repurchase agreements, any repurchase agreements held by the Funds during the fiscal year ended July 31, 2016, were received as collateral for lending securities. F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS Dividends from net investment income of each Fund, if any, are declared and paid quarterly or as the Board of Trustees may determine from time to time. Distributions of net realized gains earned by each Fund, if any, are distributed at least annually. Distributions from income and capital gains are determined in accordance with 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 significantly modified 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, 2016 was as follows:

Page 64 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2016 As of July 31, 2016, the components of distributable earnings on a tax basis for each Fund were as follows:

G. 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 the 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. Taxable years ending 2013, 2014, 2015 and 2016 remain open to federal and state audit. As of July 31, 2016, 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. Under the Regulated Investment Company Modernization Act of 2010 (the "Act"), net capital losses arising in taxable years beginning after December 22, 2010, may be carried forward indefinitely, and their character is retained as short-term and/or long-term losses. Previously, net capital losses were carried forward for up to eight years and treated as short-term losses. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses. At July 31, 2016, the Funds had pre-enactment and post-enactment net capital losses for federal income tax purposes as shown in the following table. To the extent that these loss carryforwards are used to offset future capital gains, it is probable that the capital gains so offset will not be distributed to Fund shareholders. 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.

These adjustments are primarily due to the difference between book and tax treatments of income and gains on various investment securities held by the Funds and in-kind transactions. The results of operations and net assets were not affected by these adjustments. For the fiscal year ended July 31, 2016, the adjustments for each Fund were as follows:

H. EXPENSES Expenses that are directly related to one of the Funds are charged directly to the respective Fund. General expenses of the Trust are allocated to all the Funds based upon the net assets of each Fund. FTP has entered into licensing agreements with Archipelago for each of the Funds. The license agreements allow for the use by FTP of certain trademarks and trade names of Archipelago and certain trademarks and trade names of NYSE Group. The Funds and First Trust are sub-licensees to the license agreement. The Funds are required to pay licensing fees, which are shown on the Statements of Operations. 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 Fund's business affairs and providing certain administrative services necessary for the management of the Funds. For these services, First Trust is paid an annual management fee of 0.50% of each Fund's average daily net assets. The Trust and First Trust have entered into an Expense Reimbursement, Fee Waiver and Recovery Agreement ("Recovery Agreement") in which First Trust has agreed to waive fees and/or reimburse Fund expenses to the extent that the operating expenses of each Fund (excluding interest expense, brokerage commissions and other trading expenses, acquired fund fees and expenses, taxes and extraordinary expenses) exceed 0.70% of average daily net assets per year (the "Expense Cap"). The Expense Cap will be in effect until at least November 30, 2017. Page 66 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2016 Expenses reimbursed and fees waived by First Trust under the Recovery Agreement are subject to recovery by First Trust for up to three years from the date the fee or expense was incurred, but no reimbursement payment will be made by a Fund if it results in the Fund exceeding an expense ratio equal to the Expense Cap in place at the time the expenses were reimbursed or fees waived by First Trust. These amounts would be included in "Expenses previously waived or reimbursed" on the Statements of Operations. For the fiscal year ended July 31, 2016 there were no fees waived or expenses reimbursed by First Trust for the Funds. As of July 31, 2016, none of the Funds had remaining fees previously waived or expenses reimbursed that were still subject to recovery. The Trust has multiple service agreements with The Bank of New York Mellon ("BNYM"). Under the service agreements, BNYM performs custodial, fund accounting, certain administrative services, and transfer agency services for each Fund. As custodian, BNYM is responsible for custody of each Fund's assets. As fund accountant and administrator, BNYM is responsible for maintaining the books and records of each Fund's securities and cash. As transfer agent, BNYM is responsible for maintaining shareholder records for each Fund. BNYM is a subsidiary of The Bank of New York Mellon Corporation, a financial holding company. At a meeting held on December 7, 2015, the Board of Trustees accepted Mr. Mark Bradley's resignation from his position as the President and Chief Executive Officer of the Trust, effective December 31, 2015. At the same meeting, the Board of Trustees elected Mr. James Dykas, formerly Chief Financial Officer and Treasurer of the Trust, to serve as the President and Chief Executive Officer, and Mr. Donald Swade, formerly an Assistant Treasurer of the Trust, to serve as the Treasurer, Chief Financial Officer and Chief Accounting Officer of the Trust. 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. Prior to January 1, 2016, the fixed annual retainer was allocated pro rata based on each fund's net assets. 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 or is an index fund. Additionally, the Lead Independent Trustee and the Chairmen 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 Chairmen 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 fiscal year ended July 31, 2016, the cost of purchases and proceeds from sales of investments for each Fund, excluding short-term investments and in-kind transactions, were as follows:

Page 67 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2016 5. CREATION, REDEMPTION AND TRANSACTION FEES Shares are created and redeemed by each Fund only in Creation Unit size aggregations of 50,000 shares in transactions with broker-dealers or large institutional investors that have entered into a participation agreement (an "Authorized Participant"). Such transactions are generally permitted on an in-kind basis, with a balancing cash component to equate the transaction to the daily NAV per Share of each Fund on the transaction date times the number of Shares in a Creation Unit. Authorized Participants purchasing Creation Units must pay to BNYM, as transfer agent, a standard creation transaction fee (the "Creation Transaction Fee"), which is based on the number of different securities in a Creation Unit of each Fund according to the fee schedule set forth below: Number of Securities Creation in a Creation Unit Transaction Fee ------------------------- ----------------- 1-100 $ 500 101-499 $1,000 500 or more $1,500 The Creation Transaction Fee is applicable to each purchase transaction regardless of the number of Creation Units purchased in the transaction. An additional variable fee of up to three times the Creation Transaction Fee may be charged to approximate additional expenses incurred by a Fund with respect to transactions effected outside of the clearing process (i.e., through a DTC Participant) or to the extent that cash is used in lieu of securities to purchase Creation Units. The price for each Creation Unit will equal the daily NAV per Share of a Fund on the transaction date times the number of Shares in a Creation Unit plus the fees described above and, if applicable, any transfer taxes. Authorized Participants redeeming Creation Units must pay to BNYM, as transfer agent, a standard redemption transaction fee (the "Redemption Transaction Fee"), which is based on the number of different securities in a Creation Unit of each Fund according to the fee schedule set forth below: Number of Securities Redemption in a Creation Unit Transaction Fee ------------------------- ----------------- 1-100 $ 500 101-499 $1,000 500 or more $1,500 The Redemption Transaction Fee is applicable to each redemption transaction regardless of the number of Creation Units redeemed in the transaction. An additional variable fee of up to three times the Redemption Transaction Fee may be charged to approximate additional expenses incurred by a Fund with respect to redemptions effected outside of the clearing process or to the extent that redemptions are for cash. Each Fund reserves the right to effect redemptions in cash. A shareholder may request cash redemption in lieu of securities; however, a Fund may, in its discretion, reject any such request. 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 Funds are authorized to pay an amount up to 0.25% of their average daily net assets each year to reimburse FTP, the distributor of the Funds, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or the provision of 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 June 30, 2017. 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 on 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. Page 68 -------------------------------------------------------------------------------- REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM -------------------------------------------------------------------------------- TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND: We have audited the accompanying statements of assets and liabilities of First Trust Consumer Discretionary AlphaDEX(R) Fund, First Trust Consumer Staples AlphaDEX(R) Fund, First Trust Energy AlphaDEX(R) Fund, First Trust Financials AlphaDEX(R) Fund, First Trust Health Care AlphaDEX(R) Fund, First Trust Industrials/Producer Durables AlphaDEX(R) Fund, First Trust Materials AlphaDEX(R) Fund, First Trust Technology AlphaDEX(R) Fund, and First Trust Utilities AlphaDEX(R) Fund, each a series of the First Trust Exchange-Traded AlphaDEX(R) Fund (the "Funds"), including the portfolios of investments, as of July 31, 2016, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Funds are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Funds' internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of July 31, 2016 by correspondence with the Funds' custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of each of the funds listed above included in the First Trust Exchange-Traded AlphaDEX(R) Fund as of July 31, 2016, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. /s/ Deloitte & Touche LLP Chicago, Illinois September 22, 2016 Page 69 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2016 (UNAUDITED) 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 its 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 the Funds' website located at http://www.ftportfolios.com; and (3) on the Securities and Exchange Commission's ("SEC") website at http://www.sec.gov.

These companies manufacture products and provide discretionary services directly to the consumer, and the success of these companies is tied closely to the performance of the overall domestic and Page 70 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2016 (UNAUDITED) international economy, interest rates, competition and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer discretionary products in the marketplace. CONSUMER STAPLES COMPANIES RISK. Certain of the Funds invest in consumer staples companies. Consumer staples companies provide products directly to the consumer that are typically considered non-discretionary items based on consumer purchasing habits. The success of these companies is affected by a variety of factors, such as government regulations, which may affect the permissibility of using various food additives and the production methods of companies that manufacture food products. ENERGY COMPANIES RISK. Certain of the Funds invest in energy companies. Energy companies include integrated oil companies that are involved in the exploration, production and refining process, gas distributors and pipeline-related companies and other energy companies involved with mining, producing and delivering energy-related services and drilling. General problems of energy companies include volatile fluctuations in price and supply of energy fuels, international politics, terrorist attacks, reduced demand, the success of exploration projects, clean-up and litigation costs relating to oil spills and environmental damage, and tax and other regulatory policies of various governments. Natural disasters such as hurricanes in the Gulf of Mexico also impact the petroleum industry. Oil production and refining companies are subject to extensive federal, state and local environmental laws and regulations regarding air emissions and the disposal of hazardous materials. In addition, oil prices are generally subject to extreme volatility. EQUITY SECURITIES RISK. Because the Funds invest in equity securities, the value of the Funds' shares will fluctuate with changes in the value of these 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. FINANCIAL COMPANIES RISK. Certain of the Funds invest in financial companies. Financial companies are especially subject to the adverse effects of economic recession, currency exchange rates, government regulation, decreases in the availability of capital, volatile interest rates, portfolio concentrations in geographic markets and in commercial and residential real estate loans, and competition from new entrants in their fields of business. GROWTH STOCKS INVESTMENT RISK. Growth stocks tend to be more volatile than certain other types of stocks and their prices usually fluctuate more dramatically than the overall stock market. A stock with growth characteristics can have sharp price declines due to decreases in current or expected earnings. HEALTH CARE COMPANIES RISK. Certain of the Funds invest in health care companies. Health care companies are companies involved in medical services or health care, including biotechnology research and production, drugs and pharmaceuticals and health care facilities and services. These companies are subject to extensive competition, generic drug sales or the loss of patent protection, product liability litigation and increased government regulation. Research and development costs of bringing new drugs to market are substantial, and there is no guarantee that the product will ever come to market. Health care facility operators may be affected by the demand for services, efforts by government or insurers to limit rates, restriction of government financial assistance and competition from other providers. INDEX CONSTITUENT RISK. One or more of the Funds may be a constituent of one or more indices. As a result, the Fund may be included in one or more index-tracking ETFs or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving the Fund, the size of the Fund and the market volatility of the Fund. Inclusion in an index could significantly 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, the Fund's NAV could be negatively impacted and the Fund's market price may be significantly below the Fund's net asset value during certain periods In addition, index rebalances may potentially result in increased trading activity. To the extent buying or selling activity increases, the Fund can be exposed to increased brokerage costs and adverse tax consequences and the market price of the Fund can be negatively affected. INDUSTRIALS COMPANIES RISK. Certain of the Funds invest in industrials companies. Industrials companies convert unfinished goods into finished durables used to manufacture other goods or provide services. Some industrials companies are involved in electrical equipment and components, industrial products, manufactured housing and telecommunications equipment. General risks of industrials companies include the general state of the economy, intense competition, consolidation, domestic and international politics, excess capacity and consumer demand and spending trends. In addition, they may also be significantly affected by overall capital spending levels, economic cycles, technical obsolescence, delays in modernization, labor relations, government regulations and e-commerce initiatives. Page 71 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2016 (UNAUDITED) INFORMATION TECHNOLOGY COMPANIES RISK. Certain of the Funds invest in information technology companies. Information technology companies are generally subject to the following risks: rapidly changing technologies; short product life cycles; fierce competition; aggressive pricing and reduced profit margins; the loss of patent, copyright and trademark protections; cyclical market patterns; evolving industry standards; and frequent new product introductions. Information technology companies may be smaller and less experienced companies, with limited product lines, markets or financial resources and fewer experienced management or marketing personnel. Information technology company stocks, especially those which are Internet related, have experienced extreme price and volume fluctuations that are often unrelated to their operating performance. MARKET RISK. Market risk is the risk that a particular security owned by a Fund or shares of a Fund in general may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Funds could decline in value or underperform other investments. MATERIALS AND PROCESSING COMPANIES RISK. Certain of the Funds invest in materials and processing companies. General risks of the materials sector include the general state of the economy, consolidation, domestic and international politics and excess capacity. In addition, basic materials companies may also be significantly affected by volatility of commodity prices, import controls, worldwide competition, liability for environmental damage, depletion of resources and mandated expenditures for safety and pollution control devices. NON-CORRELATION RISK. A Fund's return may not match the return of its Index for a number of reasons. For example, a Fund incurs operating expenses not applicable to its Index, and may incur costs in buying and selling securities, especially when rebalancing the Fund's portfolio holdings to reflect changes in the composition of the Index. In addition, a Fund's portfolio holdings may not exactly replicate the securities included in its Index or the ratios between the securities included in the Index. PORTFOLIO TURNOVER RISK. Certain Funds' strategies may frequently involve buying and selling portfolio securities to rebalance the Funds' exposure to various market sectors. High portfolio turnover may result in a Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause a Fund's performance to be less than you expect. REPLICATION MANAGEMENT RISK. The Funds are exposed to additional market risk due to their policy of investing principally in the securities included in the Indices. As a result of this policy, securities held by the Funds will generally not be bought or sold in response to market fluctuations. SMALLER COMPANIES RISK. Small and/or mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies. TELECOMMUNICATIONS COMPANIES RISK. Certain of the Funds invest in telecommunications companies. Telecommunications companies are subject to risks, which include increased competition and regulation by various regulatory authorities, the need to commit substantial capital and technological obsolescence. UTILITIES COMPANIES RISK. Certain of the Funds invest in utilities companies. General problems of utilities companies include the imposition of rate caps, increased competition due to deregulation, the difficulty in obtaining an adequate return on invested capital or in financing large construction projects, the limitations on operations and increased costs and delays attributable to environmental considerations and the capital market's ability to absorb utility debt. In addition, taxes, government regulation, international politics, price and supply fluctuations, volatile interest rates and energy conservation may cause difficulties for utilities. All of such issuers have been experiencing certain of these problems in varying degrees. VALUE STOCKS INVESTMENT RISK. The intrinsic value of a stock with value characteristics may not be fully recognized by the market for a long time or a stock judged to be undervalued may actually be appropriately priced at a low level. NOT FDIC INSURED NOT BANK GUARANTEED MAY LOSE VALUE Page 72 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2016 (UNAUDITED) REMUNERATION First Trust Advisors L.P. ("First Trust") is authorised and regulated by the U.S. Securities and Exchange Commission and is entitled to market shares of the First Trust Exchange-Traded AlphaDEX(R) Fund it manages (the "Funds") in the United Kingdom in accordance with the cooperation arrangements in Article 42 of the Alternative Investment Fund Managers Directive (the "Directive"). First Trust is required under the Directive to make disclosures in respect of remuneration. The following disclosures are made in line with First Trust's interpretation of currently available regulatory guidance on remuneration disclosures. During the year ended December 31, 2015, the amount of remuneration paid (or to be paid) by First Trust Advisors L.P. in respect of the Funds is $9,067,727. This figure is comprised of $453,849 paid (or to be paid) in fixed compensation and $8,613,878 paid (or to be paid) in variable compensation. There were a total of 13 beneficiaries of the remuneration described above. Those amounts include $5,011,396 paid (or to be paid) to senior management of First Trust Advisors L.P. and $4,056,331 paid (or to be paid) to other employees whose professional activities have a material impact on the risk profiles of First Trust Advisors L.P. or the Funds (collectively, "Code Staff"). Code Staff included in the aggregated figures disclosed above are rewarded in line with First Trust's remuneration policy (the "Remuneration Policy") which is determined and implemented by First Trust's senior management. The Remuneration Policy reflects First Trust's ethos of good governance and encapsulates the following principal objectives: i. to provide a clear link between remuneration and performance of First Trust and to avoid rewarding for failure; ii. to promote sound and effective risk management consistent with the risk profiles of the Funds managed by First Trust; and iii. to remunerate staff in line with the business strategy, objectives, values and interests of First Trust and the Funds managed by First Trust in a manner that avoids conflicts of interest. First Trust assesses various risk factors which it is exposed to when considering and implementing remuneration for Code Staff and considers whether any potential award to such person(s) would give rise to a conflict of interest. First Trust does not reward failure, or consider the taking of risk or failure to take risk in its remuneration of Code Staff. First Trust assesses performance for the purposes of determining payments in respect of performance-related remuneration of Code Staff by reference to a broad range of measures including (i) individual performance (using financial and non-financial criteria), and (ii) the overall performance of First Trust. Remuneration is not based upon the performance of the Funds. The elements of remuneration are balanced between fixed and variable and the senior management sets fixed salaries at a level sufficient to ensure that variable remuneration incentivises and rewards strong individual performance but does not encourage excessive risk taking. No individual is involved in setting his or her own remuneration. ADVISORY AGREEMENT BOARD CONSIDERATIONS REGARDING CONTINUATION OF INVESTMENT MANAGEMENT AGREEMENT The Board of Trustees (the "Board") of the First Trust Exchange-Traded AlphaDEX(R) Fund (the "Trust"), including the Independent Trustees, unanimously approved the continuation of the Investment Management Agreement (the "Agreement") with First Trust Advisors L.P. (the "Advisor" or "First Trust") on behalf of the following nine series of the Trust (each a "Fund" and collectively, the "Funds"): First Trust Consumer Discretionary AlphaDEX(R) Fund (FXD) First Trust Consumer Staples AlphaDEX(R) Fund (FXG) First Trust Energy AlphaDEX(R) Fund (FXN) First Trust Financials AlphaDEX(R) Fund (FXO) First Trust Health Care AlphaDEX(R) Fund (FXH) First Trust Industrials/Producer Durables AlphaDEX(R) Fund (FXR) First Trust Materials AlphaDEX(R) Fund (FXZ) First Trust Technology AlphaDEX(R) Fund (FXL) First Trust Utilities AlphaDEX(R) Fund (FXU) Page 73 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2016 (UNAUDITED) The Board approved the continuation of the Agreement for each Fund for a one-year period ending June 30, 2017 at a meeting held on June 13, 2016. The Board determined for each Fund that the continuation of the Agreement is in the best interests of the Fund in light of the extent and quality of the services provided and such other matters as the Board considered to be relevant in the exercise of its reasonable business judgment. To reach this determination for each Fund, the Board considered its duties under the Investment Company Act of 1940, as amended (the "1940 Act"), as well as under the general principles of state law in reviewing and approving advisory contracts; the requirements of the 1940 Act in such matters; the fiduciary duty of investment advisors with respect to advisory agreements and compensation; the standards used by courts in determining whether investment company boards have fulfilled their duties; and the factors to be considered by the Board in voting on such agreements. At meetings held on April 22, 2016 and June 13, 2016, the Board, including the Independent Trustees, reviewed materials provided by the Advisor responding to requests for information from counsel to the Independent Trustees that, among other things, outlined the services provided by the Advisor to each Fund (including the relevant personnel responsible for these services and their experience); the advisory fee rate payable by each Fund as compared to fees charged to a peer group of funds (all of which were exchange-traded funds ("ETFs")) compiled by Management Practice, Inc. ("MPI"), an independent source (the "MPI Peer Group"), and as compared to fees charged to other clients of the Advisor, including other ETFs managed by the Advisor; expenses of each Fund as compared to expense ratios of the funds in the Fund's MPI Peer Group; performance information for each Fund; the nature of expenses incurred in providing services to each Fund and the potential for economies of scale, if any; financial data on the Advisor; any fall-out benefits to the Advisor and its affiliate, First Trust Portfolios L.P. ("FTP"); and information on the Advisor's compliance program. The Board reviewed initial materials with the Advisor at a special meeting held on April 22, 2016, prior to which the Independent Trustees and their counsel met separately to discuss the information provided by the Advisor. Following the April meeting, independent legal counsel on behalf of the Independent Trustees requested certain clarifications and supplements to the materials provided, and the information provided in response to those requests was considered at an executive session of the Independent Trustees and independent legal counsel held prior to the June 13, 2016 meeting, as well as at the meeting held that day. The Board applied its business judgment to determine whether the arrangement between the Trust and the Advisor continues to be a reasonable business arrangement from each Fund's perspective as well as from the perspective of shareholders. The Board determined that, given the totality of the information provided with respect to the Agreement, the Board had received sufficient information to renew the Agreement. The Board considered that shareholders chose to invest or remain invested in a Fund knowing that the Advisor manages the Fund and knowing the Fund's advisory fee. In reviewing the Agreement for each Fund, the Board considered the nature, extent and quality of the services provided by the Advisor under the Agreement. The Board considered that the Advisor is responsible for the overall management and administration of the Trust and each Fund and reviewed all of the services provided by the Advisor to the Funds, as well as the background and experience of the persons responsible for such services. In reviewing the services provided, the Board noted the compliance program that had been developed by the Advisor and considered that it includes a robust program for monitoring the Advisor's and each Fund's compliance with the 1940 Act, as well as each Fund's compliance with its investment objective and policies. In addition, as part of the Board's consideration of the Advisor's services, the Advisor, in its written materials and at the April 22, 2016 meeting, described to the Board the scope of its ongoing investment in additional infrastructure and personnel to maintain and improve the quality of services provided to the Funds and the other funds in the First Trust Fund Complex. In light of the information presented and the considerations made, the Board concluded that the nature, extent and quality of the services provided to the Trust and each Fund by the Advisor under the Agreement have been and are expected to remain satisfactory and that the Advisor has managed each Fund consistent with the Fund's investment objective and policies. The Board considered the advisory fee rate payable by each Fund under the Agreement for the services provided. The Board considered that the Advisor agreed to extend the current expense cap for each Fund through November 30, 2017. For each Fund, the Board noted that expenses borne or fees waived by the Advisor are to be subject to reimbursement by the Fund for up to three years from the date the expense was incurred or fee was waived, but no reimbursement payment would be made by the Fund if it would result in the Fund exceeding an expense ratio equal to the expense cap in place at the time the expenses were borne or fees were waived by the Advisor. The Board received and reviewed information showing the advisory or unitary fee rates and expense ratios of the peer funds in the MPI Peer Groups, as well as advisory fee and unitary fee rates charged by the Advisor to other fund (including ETFs) and non-fund clients. Because each Fund's MPI Peer Group included peer funds that pay a unitary fee, the Board determined that expense ratios were the most relevant comparative data point. Based on the information provided, the Board noted that the total (net) expense ratio of each Fund was above the median total (net) expense ratio of the peer funds in each Fund's respective MPI Peer Group. With respect to the MPI Peer Groups, the Board discussed with representatives of the Advisor limitations in creating peer groups for index ETFs, including differences in underlying indexes and index-tracking methodologies that can result in greater management complexities across seemingly comparable ETFs, and different business models that may affect the pricing of services among ETF sponsors. The Board took these limitations and differences into account in considering the peer data. With Page 74 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND SECTOR FUNDS JULY 31, 2016 (UNAUDITED) respect to fees charged to other clients, the Board considered differences between the Funds and other clients that limited their comparability. In considering the advisory fee rates overall, the Board also considered the Advisor's statement that it seeks to meet investor needs through innovative and value-added investment solutions and the Advisor's description of its long-term commitment to each Fund. The Board considered performance information for each Fund. The Board noted the process it has established for monitoring each Fund's performance and portfolio risk on an ongoing basis, which includes quarterly performance reporting from the Advisor for the Funds. The Board determined that this process continues to be effective for reviewing each Fund's performance. The Board received and reviewed information for periods ended December 31, 2015 regarding the performance of each Fund's underlying index, the correlation between each Fund's performance and that of its underlying index, each Fund's tracking difference and each Fund's excess return as compared to its benchmark index. The Board considered the Advisor's explanations of how the AlphaDEX(R) stock selection methodology impacts Fund performance in various market environments, and the Advisor's statement that AlphaDEX(R) is designed to provide long-term outperformance. Based on the information provided and its ongoing review of performance, the Board concluded that each Fund was correlated to its underlying index and that the tracking difference for each Fund was consistent with the Fund's prospectus. In addition, the Board reviewed data prepared by MPI comparing each Fund's performance to its respective MPI Peer Group and to one or more broad-based benchmark indexes, but given each Fund's objective of seeking investment results that correspond generally to the performance of its underlying index, the Board placed more emphasis on its review of correlation and tracking difference. On the basis of all the information provided on the fees, expenses and performance of each Fund and the ongoing oversight by the Board, the Board concluded that the advisory fee for each Fund continues to be reasonable and appropriate in light of the nature, extent and quality of the services provided by the Advisor to each Fund under the Agreement. The Board considered information and discussed with the Advisor whether there were any economies of scale in connection with providing advisory services to the Funds and noted the Advisor's statement that it expects its expenses to increase over the next twelve months as the Advisor continues to make investments in personnel and infrastructure. The Board considered the revenues and allocated costs (including the allocation methodology) of the Advisor in serving as investment advisor to each Fund for the twelve months ended December 31, 2015 and the estimated profitability level for each Fund calculated by the Advisor based on such data, as well as complex-wide and product-line profitability data for the same period. The Board noted the inherent limitations in the profitability analysis, and concluded that, based on the information provided, the Advisor's profitability level for each Fund was not unreasonable. The Board considered that the Advisor had identified as a fall-out benefit to the Advisor and FTP their exposure to investors and brokers who, absent their exposure to the Funds, may have had no dealings with the Advisor or FTP, and noted that the Advisor does not utilize soft dollars in connection with its management of the Funds' portfolios. Based on all of the information considered and the conclusions reached, the Board, including the Independent Trustees, unanimously determined that the terms of the Agreement continue to be fair and reasonable and that the continuation of the Agreement is in the best interests of the Trust and each Fund. No single factor was determinative in the Board's analysis.

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 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 AlphaDEX(R) Fund (the "Trust") described in this report (each such series is referred to as a "Fund" and collectively, as the "Funds") to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. When evaluating the information included in this report, you are cautioned not to place undue reliance on these forward-looking statements, which reflect the judgment of the Advisor and its representatives only as of the date hereof. 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 shares may therefore be less than what you paid for them. Accordingly, you can lose money investing in a Fund. See "Risk Considerations" in the Additional Information Section of this report for a discussion of other risks in 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 http://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 webpage at http://www.ftportfolios.com.

Page 1 -------------------------------------------------------------------------------- SHAREHOLDER LETTER -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND ANNUAL LETTER FROM THE CHAIRMAN AND CEO JULY 31, 2016 Dear Shareholders: Thank you for your investment in the Style Funds of First Trust Exchange-Traded AlphaDEX(R) Fund. First Trust Advisors L.P. ("First Trust") is pleased to provide you with the annual report which contains detailed information about your investment for the 12 months ended July 31, 2016, including a market overview and a performance analysis for the period. We encourage you to read this report and discuss it with your financial advisor. While markets were up and down during 2015, we believe there are three important things to remember. First, the U.S. economy grew, despite the massive decline in oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the "Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated rate hike by the Fed in December 2015 had little effect on the money supply, and the stock market was not shocked by the hike. Early in 2016, many investors were concerned that the volatility we saw in the market in 2015 would continue, and it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index declined by 10.27%. Since then, the market has made a steady comeback, and from February 11, 2016 to July 31, 2016, the S&P 500(R) Index was up 19.99%. First Trust believes that having a long-term investment horizon and investing in quality products can help you reach your goals, regardless of how the market behaves. We have always maintained perspective about the markets and believe investors should as well. We will continue to strive to provide quality investment opportunities each and every day, which has been one of the hallmarks of our firm since its inception 25 years ago. Thank you for giving First Trust the opportunity to be a part of your investment plan. We value our relationship with you and will continue to focus on helping investors like you reach your financial goals. Sincerely, /s/ James A. Bowen James A. Bowen Chairman of the Board of Trustees Chief Executive Officer of First Trust Advisors L.P. Page 2 -------------------------------------------------------------------------------- MARKET OVERVIEW -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND ANNUAL REPORT JULY 31, 2016 ROBERT F. CAREY, CFA SENIOR VICE PRESIDENT AND CHIEF MARKET STRATEGIST FIRST TRUST ADVISORS L.P. Mr. Carey is responsible for the overall management of research and analysis of the First Trust product line. Mr. Carey has over 25 years of experience as an Equity and Fixed-Income Analyst and is a recipient of the Chartered Financial Analyst ("CFA") designation. He is a graduate of the University of Illinois at Champaign-Urbana with a B.S. in Physics. He is also a member of the Investment Analysts Society of Chicago and the CFA Institute. Mr. Carey has appeared as a guest on such programs as Bloomberg TV, CNBC, and WBBM Radio, and has been quoted by several publications, including The Wall Street Journal, The Wall Street Reporter, Bloomberg News Service, and Registered Rep. STATE OF THE U.S./GLOBAL ECONOMY One of the reasons cited by the Federal Reserve for not raising interest rates beyond the initial 0.25% hike in the federal funds target rate on December 16, 2015 is the slowdown in global growth. The International Monetary Fund reduced its global growth estimate for 2016 from 3.3% in April to 3.2% in July. It also shaved its 2017 estimate by 0.1% to 3.5%, according to its own release. To help put this concern into perspective, the rate was 5.4% in 2010. The rebound in the price of crude oil is boosting Mergers & Acquisitions ("M&A") activity in the energy sector, according to Bloomberg. From February 11, 2016 (multi-year low) through August 25, 2016, the price of a barrel of crude oil rose 80.6%, from $26.21 to $47.33. Wood Mackenzie, a consulting firm, reported that more than $11 billion worth of oil and gas transactions were announced globally in July. It was the highest monthly total so far this year. Since May, deal volume has totaled $32 billion. Wood Mackenzie believes that M&A activity will continue to accelerate as oil prices stabilize. Higher energy prices, if sustained, could help boost global economic growth moving forward. Many nations around the globe rely fairly heavily on the sale of crude oil to help fund their economies, in our opinion. ETFGI, an industry research group, reported that total assets invested in exchange-traded funds (ETFs) and other exchange-traded products (ETPs) reached a record high of $3.34 trillion globally in July 2016, according to its own release. Total assets invested in U.S. ETFs/ETPs reached a record high of $2.37 trillion in July 2016. STYLE/MARKET CAP INVESTING One barometer for gauging investors' appetites for equities is tracking money flows in and out of open-end mutual funds and ETFs. For the 12-month period ended July 31, 2016, U.S. Equity funds/ETFs reported net outflows totaling over $47 billion, according to data from Morningstar. Investors continue to favor passive funds over actively managed funds. Passive U.S. Equity funds/ETFs reported net inflows totaling $163.6 billion, compared to net outflows totaling $211.0 billion for actively managed U.S. Equity funds/ETFs. For the 12-month period ended July 2016, Morningstar reported the following net flows for these nine Style/Market Cap fund categories: $51.2 billion (Large Blend); $1.1 billion (Large Value); -$58.8 billion (Large Growth); -$2.2 billion (Mid-Cap Blend); -$6.4 billion (Mid-Cap Value); -$20.3 billion (Mid-Cap Growth); -$0.4 billion (Small Blend); $2.6 billion (Small Value); and -$14.4 billion (Small Growth). Slow and steady appears to be winning the race, in our opinion. Despite the moderate pace of economic growth since the previous recession ended in 2009, the current bull market in stocks is the second-longest in U.S. history at 2,701 days through July, as measured by the S&P 500(R) Index, according to Bespoke Investment Group. From March 9, 2009 to July 29, 2016, the S&P 500(R) Index posted a cumulative total return of 275.51%, according Bloomberg. From 2009 to 2015, the S&P 500(R) Index increased its annual earnings from $58.15 to $109.32, according to Bloomberg. Currently, Bloomberg's consensus estimates for 2016 and 2017 are $117.73 and $133.11, respectively. Page 3 -------------------------------------------------------------------------------- FUND PERFORMANCE OVERVIEW (UNAUDITED) -------------------------------------------------------------------------------- FIRST TRUST LARGE CAP CORE ALPHADEX(R) FUND (FEX) From the beginning of the period covered by this report until April 8, 2016, the First Trust Large Cap Core AlphaDEX(R) Fund (the "Fund") sought investment results that corresponded generally to the price and yield (before the Fund's fees and expenses) of an equity index called the Defined Large Cap Core Index. Effective April 8, 2016, the Fund changed its investment objective to seek investment results that correspond generally to the price and yield (before the Fund's fees and expenses) of an equity index called the Nasdaq AlphaDEX(R) Large Cap Core Index (the "Index"). The Fund will normally invest at least 90% of its net assets in common stocks that comprise the Index. From the beginning of the period covered by this report until April 8, 2016, the shares of the Fund traded on the NYSE Arca. Effective April 8, 2016, the shares of the Fund are listed and trade on The Nasdaq Stock Market LLC under the ticker symbol "FEX." The Fund commenced trading on May 9, 2007. The Index employs the AlphaDEX(R) stock selection methodology which uses fundamental growth and value factors to objectively select stocks from the Nasdaq US 500 Large Cap Index that may generate positive alpha relative to traditional passive indices. The Index is a modified equal-dollar weighted index where higher ranked stocks receive a higher weight within the Index.

(1) The Defined Large Cap Core Index was replaced with the Nasdaq AlphaDEX(R) Large Cap Core Index. The new index is substantially similar to the old index. (2) Performance data is not available for all the periods shown in the table for the index because performance data does not exist for each of the entire periods. (3) The Fund's cumulative total returns from April 8, 2016 through July 31, 2016 were 7.33% and 7.38% at NAV and Market Price, respectively. That compares to an Index return of 7.54% for the same period. (See Notes to Fund Performance Overview on page 28.) PERFORMANCE REVIEW FEX's one-year net asset value ("NAV") return of 3.59% underperformed the benchmark S&P 500(R) Index return of 5.61% by -2.02%. The Utilities sector was the leading contributing sector during the period with a 1.9% contribution, 24.2% return, and 8.4% average weighting. The Gas Utilities industry had an impressive 51.9% return, but was limited to a 0.2% contribution due to its small allocation of 0.4%. The Consumer Discretionary sector was given the highest weighting during the period at 19%, and due to its -3.6% return, contributed -1.1% to the Fund's return. Amongst the Consumer Discretionary sector, securities held within the Multiline Retail industry such as Kohls Co., Macy's Inc., and Nordstrom, Inc. had a -21.9% return and contributed -0.4% to the Fund's return. On a relative basis the Fund underperformed the benchmark primarily due to the Consumer Discretionary sector where the Fund was overweight the sector by 6.2% and underperformed by -7.1%, creating -1.7% of relative underperformance. The Financials sector, the second highest weighted sector during the period at 15.2%, reversed 1.3% of underperformance by outperforming the benchmark by 4.9%.

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. FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS BID/ASK MIDPOINT VS. NAV AS OF JULY 31, 2016 The following Frequency Distribution of Discounts and Premiums charts are provided to show the frequency at which the bid/ask midpoint price for the Fund was at a discount or premium to the daily NAV. The following tables are for comparative purposes only and represent the period August 1, 2011 through July 31, 2016. Shareholders may pay more than NAV when they buy Fund shares and receive less than NAV when they sell those shares because shares are bought and sold at current market price.

That compares to an Index return of 8.59% for the same period. (See Notes to Fund Performance Overview on page 28.) PERFORMANCE REVIEW FNX's one-year NAV return of 0.76% underperformed the benchmark S&P MidCap 400(R) Index return of 5.53% by -4.77%. The Financials sector contributed the most during the period to the Fund's return, with a 2.5% contribution stemming from its high 21.8% allocation and 6.6% return. Amongst this sector, the Real Estate Investment Trust ("REIT") industry contributed 2.8% to the Fund's return. REITs had a return of 29.8% during the period. The Energy sector was the Fund's worst performing sector with a -29.3% return, contributing -3.1% to the Fund's return, and given an average allocation of 6.4% during the period. The two industries within the Energy sector, the Oil Gas & Consumable Fuels and the Energy Equipment & Services contributed -1.9% and -1.2%, respectively, to the Fund's return. On a relative basis the Fund underperformed the benchmark. The Energy sector caused -1.4% of the underperformance by allocating 2.8% more of the Fund's weighting to the -29.3% returning sector. Several securities contributed to this sectors underperformance including Atwood Oceanics, Inc. (-0.40%), SM Energy Co. (-0.30%), and Western Refining, Inc. (-0.20%). The Utilities sector, which was the top returning sector during the period at 31.0%, reversed 0.6% of underperformance as the Fund was slightly overweight the benchmark by 0.6%.

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. FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS BID/ASK MIDPOINT VS.

Effective April 8, 2016, the Fund changed its investment objective to seek investment results that correspond generally to the price and yield (before the Fund's fees and expenses) of an equity index called the Nasdaq AlphaDEX(R) Small Cap Core Index (the "Index"). The Fund will normally invest at least 90% of its net assets in common stocks that comprise the Index. From the beginning of the period covered by this report until April 8, 2016, the shares of the Fund traded on the NYSE Arca. Effective April 8, 2016, the shares of the Fund are listed and trade on The Nasdaq Stock Market LLC under the ticker symbol "FYX." The Fund commenced trading on May 9, 2007. The Index employs the AlphaDEX(R) stock selection methodology which uses fundamental growth and value factors to objectively select stocks from the Nasdaq US 700 Small Cap Index that may generate positive alpha relative to traditional passive indices. The Index is a modified equal-dollar weighted index where higher ranked stocks receive a higher weight within the Index.

(2) Performance data is not available for all the periods shown in the table for the index because performance data does not exist for each of the entire periods. (3) The Fund's cumulative total returns for the period from April 8, 2016 through July 31, 2016 were 12.13% and 12.33% at NAV and Market Price, respectively. That compares to an Index return of 12.33% for the same period. (See Notes to Fund Performance Overview on page 28.) PERFORMANCE REVIEW FYX's one-year NAV return of 2.20% underperformed the benchmark S&P SmallCap 600(R) Index return of 5.96% by -3.76%. The Information Technology sector contributed the most to the Fund's return during the period with a 2.8% contribution. This sector had a 16.2% allocation and 19.5% return. Within the Information Technology sector, the Diversified Telecommunication Services industry had an impressive 57.9% return.

On a relative basis the Fund underperformed the benchmark primarily due to the Energy sector. This sector had a -7.5% lower return during the period and was given a 2.0% greater allocation. It was the Energy Equipment & Services industry that created the most underperformance within the Energy sector, creating -1.6% drag from its -19.1% lower return, relative to the benchmark. The Financials and Information Technology sectors each reversed about 0.34% of drag by outperforming the benchmark.

The Energy sector contributed -1.9% to the Fund's return during the period as it had a -9.8% return and 12.3% allocation. The Oil Gas & Consumables industry contributed -1.2% of the -1.9% due to the fact that the Fund had a return of -8.6% and 9.5% allocation within the industry. The Utilities sector was by far the leading sector in terms of contribution. The Utilities sector contributed 2.9% as a result of the Fund's 23.5% return and 13.5% allocation. The Multi-Utilities and Electric Utilities industries each accounted for about 1.5% of contribution. On a relative basis, the Fund underperformed the benchmark. The Energy sector accounted for -2.3% of the underperformance due to the Fund having a -17.1% worse relative return. Several securities contributed to the sectors underperformance, including Southwestern Energy Co. (-0.4% of underperformance), Exxon Mobil Corp. (-0.38%), and HollyFrontier Co., (-0.28%). The Financials sector reversed close to 2.1% of underperformance within the Banking industry by underweighting the benchmark by 5.3% and outperforming the benchmark by 1.8%.

Effective April 8, 2016, the Fund changed its investment objective to seek investment results that correspond generally to the price and yield (before the Fund's fees and expenses) of an equity index called the Nasdaq AlphaDEX(R) Multi Cap Value Index (the "Index"). The Fund will normally invest at least 90% of its net assets in common stocks that comprise the Index. From the beginning of the period covered by this report until April 8, 2016, the shares of the Fund traded on the NYSE Arca. Effective April 8, 2016, the shares of the Fund are listed and trade on The Nasdaq Stock Market LLC under the ticker symbol "FAB." The Fund commenced trading on May 9, 2007. The Index employs the AlphaDEX(R) stock selection methodology which uses fundamental growth and value factors to objectively select value stocks from the Nasdaq US 500 Large Cap Index, Nasdaq US 600 Mid Cap Index and Nasdaq US 700 Small Cap Index (together the "Nasdaq US Multi Cap Value Index") that may generate positive alpha relative to traditional passive indices. The Index is a modified equal-dollar weighted index where higher ranked stocks receive a higher weight within the Index.

Effective April 8, 2016, the Fund changed its investment objective to seek investment results that correspond generally to the price and yield (before the Fund's fees and expenses) of an equity index called the Nasdaq AlphaDEX(R) Mid Cap Value Index (the "Index"). The Fund will normally invest at least 90% of its net assets in common stocks that comprise the Index. From the beginning of the period covered by this report until April 8, 2016, the shares of the Fund traded on the NYSE Arca. Effective April 8, 2016, the shares of the Fund are listed and trade on The Nasdaq Stock Market LLC under the ticker symbol "FNK." The Fund commenced trading on April 20, 2011. The Index employs the AlphaDEX(R) stock selection methodology which uses fundamental growth and value factors to objectively select value stocks from the Nasdaq US 600 Mid Cap Index that may generate positive alpha relative to traditional passive indices. The Index is a modified equal-dollar weighted index where higher ranked stocks receive a higher weight within the Index.

(1) The Defined Mid Cap Value Index was replaced with the Nasdaq AlphaDEX(R) Mid Cap Value Index. The new index is substantially similar to the old index. (2) Performance data is not available for all the periods shown in the table for the index because performance data does not exist for each of the entire periods. (3) The Fund's cumulative total returns for the period from April 8, 2016 through July 31, 2016 were 7.93% and 8.11% at NAV and Market Price, respectively. That compares to an Index return of 8.16% for the same period. (See Notes to Fund Performance Overview on page 28.) PERFORMANCE REVIEW FNK's one-year NAV return of 1.22% underperformed the benchmark S&P MidCap 400(R) Value Index return of 7.81% by -6.59%. The Utilities and Financials sectors each contributed about 2.4% to the Fund's return. The Utilities sector had a high contribution due to its 34.0% return during the period, the highest return amongst the sectors during the period. The Financials sector had a high contribution due to its high allocation of 22.2%, the highest allocation amongst the sectors during the period. The REIT industry in particular, within the Financials sector, contributed 1.5% alone to the Fund's return from its 4.4% allocation and 15.2% return. On a relative basis, the Fund underperformed the benchmark. The Energy sector caused -2.3% of underperformance as the Fund was overweight the benchmark by 3.8% and underperformed the benchmark by -4.0%. Both of the industries within the Energy sector, the Energy Equipment & Services and Oil Gas & Consumable Fuels industries, contributed about -1.15% to the Fund's return. The Utilities sector reversed 0.6% of underperformance as the Fund outperformed the benchmark by 3.2%. Electric Utilities accounted for nearly half of the Utilities sector's outperformance by having a 3.5% higher return than the benchmark.

PERFORMANCE REVIEW FNY's one-year NAV return of 0.03% underperformed the benchmark S&P MidCap 400(R) Growth Index return of 3.32% by -3.29%. The Financials sector contributed the most during the period to the Fund's return, with a 2.9% contribution stemming from its high 21.8% allocation and 8.1% return. Amongst this sector, the REIT industry contributed 4.7% to the Fund's return. REITs had a return of 38.9% during the period. The Consumer Discretionary sector was the Fund's third highest weighted sector during the period at 17.8% and the Fund's worst contributing sector with a -2.7% contribution, stemming from its -5.8% return. The Hotels Restaurants & Leisure industry in particular contributed -1.1% to the Fund's return due to its higher weighting of 5.1% and return of -4.4%. On a relative basis, the Fund underperformed the benchmark. The underperformance can be attributed primarily to the Health Care sector, which was given a 13.9% allocation during the period, where the Fund underperformed the benchmark by -10.1%, creating -1.8% of drag. The Life Sciences Tools & Services industry, within the Health Care sector, was the cause of -0.8% of the underperformance. The Industrials sector, which was given a weighting of 11.1% during the period, reversed close to 1.1% of underperformance by outperforming the benchmark by 8.1%. The Airlines industry alone, within the Industrials sector, reversed 0.5% of underperformance by underweighting the poor performing industry (-26.9% return).

PERFORMANCE REVIEW FYT's one-year NAV return of 0.79% underperformed the benchmark S&P SmallCap 600(R) Value Index return of 8.95% by -8.16%. Several sectors contributed equally to the Fund's return during the period including the Information Technology (2% contribution), Industrials (1.9% contribution), Financials (1.7% contribution), and Utilities (1.6% contribution) sectors. The highest weighted sector during the period was the Consumer Discretionary sector at 19.4%, but it had a near flat contribution due to its -8.4% return. The Energy sector was the worst performing and contributing sector during the period. This sector had a -40.9% return and -7.1% contribution to the Fund's return. The contribution was tampered due to its relatively low weighting of 8.5% during the period. On a relative basis, the Fund underperformed the benchmark. It was the Energy sector that contributed the most to the relative underperformance. The Fund held the Energy sector at a 4.2% greater allocation and had a -8.2% lower return, leading to -4.7% of relative underperformance. The two industries within the Energy sector, the Oil Gas & Consumable Fuels and Energy Equipment & Services industries, each contributed about -2.3% to the underperformance, each overweighting and underperforming the benchmark. The Health Care sector reversed 0.5% of drag by underweighting the benchmark by 3.8% and outperforming the benchmark by 1.5%.

Effective April 8, 2016, the Fund changed its investment objective to seek investment results that correspond generally to the price and yield (before the Fund's fees and expenses) of an equity index called the Nasdaq AlphaDEX(R) Small Cap Growth Index (the "Index"). The Fund will normally invest at least 90% of its net assets in common stocks that comprise the Index. From the beginning of the period covered by this report until April 8, 2016, the shares of the Fund traded on the NYSE Arca. Effective April 8, 2016, the shares of the Fund are listed and trade on The Nasdaq Stock Market LLC under the ticker symbol "FYC." The Fund commenced trading on April 20, 2011. The Index employs the AlphaDEX(R) stock selection methodology which uses fundamental growth and value factors to objectively select growth stocks from the Nasdaq US 700 Small Cap Index that may generate positive alpha relative to traditional passive indices. The Index is a modified equal-dollar weighted index where higher ranked stocks receive a higher weight within the Index.

(1) The Defined Small Cap Growth Index was replaced with the Nasdaq AlphaDEX(R) Small Cap Growth Index. The new index is substantially similar to the old index. (2) Performance data is not available for all the periods shown in the table for the index because performance data does not exist for each of the entire periods. (3) The Fund's cumulative total returns for the period from April 8, 2016 through July 31, 2016 were 12.48% and 12.61% at NAV and Market Price, respectively. That compares to an Index return of 12.75% for the same period. (See Notes to Fund Performance Overview on page 28.) PERFORMANCE REVIEW FYC's one-year NAV return of 3.54% outperformed the benchmark S&P SmallCap 600(R) Growth Index return of 3.27% by 0.27%. The Information Technology sector was the top contributing sector during the period at 3.8%. This sector had an 18.2% allocation and 19.3% return. Several industries within the Information Technology sector posted high returns during the period including Diversified Telecommunication Services (57.9%), IT Services (31.1%), and Semiconductors & Semiconductor Equipment (29.0%). The Health Care sector was the worst contributing sector during the period at -3.3%. This sector had a 21.1% allocation during the period, the highest amongst the sectors, and a -5.2% return. The Pharmaceuticals industry returned -27.4% during the period and contributed -1.6% to the Fund's return. On a relative basis, the Fund outperformed the benchmark primarily due to the Financials sector. This sector was given the second highest allocation during the period at 20.9%, 3.7% lower than the benchmark. The sector also had a 6.3% higher return than the benchmark, leading to 1.5% of relative outperformance. The Health Care sector reversed 2.5% of outperformance as the Fund was overweight the benchmark by 2.4% and underperformed by -8.1%.

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.

That compares to an Index return of 5.10% for the same period. (See Notes to Fund Performance Overview on page 28.) PERFORMANCE REVIEW FMK's one-year NAV return of 0.19% underperformed the benchmark S&P 100(R) Index return of 5.75% by -5.56%. The Information Technology sector was given the greatest allocation of 22.9% and had a return of 7.5%, leading to a 1.4% contribution to the Fund's return. In the Information Technology sector, the Semiconductor & Semiconductor Equipment industry contributed 0.9%, due to its 15.6% return and 6.7% allocation. The Health Care sector deterred -3.5% of Fund performance as this sector had a -16.9% return and 11.7% allocation. The Biotechnology industry caused -1.9% of the sector's contribution. The Biotechnology industry was given an allocation of 4.1% and had a return of -28.9%. On a relative basis, the Fund underperformed the benchmark. The underperformance can be largely attributed to the Health Care sector. The Health Care sector caused -3.3% of underperformance as it had an -18.9% lower return. The Biotechnology and Pharmaceuticals industries each contributed about -1.1% of underperformance due to underperforming the benchmark by -16.1% and -23.9% respectively. The Financials sector reversed 1.7% of underperformance as the Fund was underweight the benchmark in this poor performing sector (-12.2% return) by 6.1%. The Banking industry, in particular, was the cause of 1.6% of the outperformance as the Fund underweighted the benchmark by 4.3% and outperformed the benchmark by 5.1%.

"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. For certain Funds the total returns would have been lower if certain fees had not been waived and expenses reimbursed 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 between the highest bid and the lowest offer on the stock exchange on which shares of the Fund are listed for trading as of the time that the Fund's NAV is 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. Page 28 FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS UNDERSTANDING YOUR FUND EXPENSES JULY 31, 2016 As a shareholder of First Trust Large Cap Core AlphaDEX(R) Fund, First Trust Mid Cap Core AlphaDEX(R) Fund, First Trust Small Cap Core AlphaDEX(R) Fund, First Trust Large Cap Value AlphaDEX(R) Fund, First Trust Large Cap Growth AlphaDEX(R) Fund, First Trust Multi Cap Value AlphaDEX(R) Fund, First Trust Multi Cap Growth AlphaDEX(R) Fund, First Trust Mid Cap Value AlphaDEX(R) Fund, First Trust Mid Cap Growth AlphaDEX(R) Fund, First Trust Small Cap Value AlphaDEX(R) Fund, First Trust Small Cap Growth AlphaDEX(R) Fund or First Trust Mega Cap AlphaDEX(R) Fund (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 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 July 31, 2016. 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 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 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.

ORGANIZATION First Trust Exchange-Traded AlphaDEX(R) Fund (the "Trust") is an open-end management investment company organized as a Massachusetts business trust on December 6, 2006, 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 twenty-one exchange-traded funds considered either a Sector Fund or Style Fund. This report covers the twelve Style Funds listed below. The shares of each Style Fund are listed and traded on The Nasdaq Stock Market LLC ("Nasdaq"). First Trust Large Cap Core AlphaDEX(R) Fund - (ticker "FEX") (1) First Trust Mid Cap Core AlphaDEX(R) Fund - (ticker "FNX") (1) First Trust Small Cap Core AlphaDEX(R) Fund - (ticker "FYX") (1) First Trust Large Cap Value AlphaDEX(R) Fund - (ticker "FTA") (1) First Trust Large Cap Growth AlphaDEX(R) Fund - (ticker "FTC") (1) First Trust Multi Cap Value AlphaDEX(R) Fund - (ticker "FAB") (1) First Trust Multi Cap Growth AlphaDEX(R) Fund - (ticker "FAD") (1) First Trust Mid Cap Value AlphaDEX(R) Fund - (ticker "FNK") (1) First Trust Mid Cap Growth AlphaDEX(R) Fund - (ticker "FNY") (1) First Trust Small Cap Value AlphaDEX(R) Fund - (ticker "FYT") (1) First Trust Small Cap Growth AlphaDEX(R) Fund - (ticker "FYC") (1) First Trust Mega Cap AlphaDEX(R) Fund - (ticker "FMK") (1) (1) Formerly traded on the NYSE Arca, Inc. Each fund represents a separate series of shares of beneficial interest in the Trust (each a "Fund" and collectively, the "Funds"). Unlike conventional mutual funds, each Fund issues and redeems shares on a continuous basis, at net asset value ("NAV"), only in large specified blocks consisting of 50,000 shares called a "Creation Unit." Creation Units are issued and redeemed principally in-kind for securities included in a Fund's relevant index. Except when aggregated in Creation Units, each Fund's shares are not redeemable securities. Effective April 8, 2016, the investment objective of each Fund is to seek investment results that correspond generally to the price and yield (before the Fund's fees and expenses) of the following indices:

SIGNIFICANT ACCOUNTING POLICIES The Funds, each of which is an investment company within the scope of Financial Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follow accounting and reporting guidance under FASB 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. Page 127 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2016 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 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 adopted by the Trust's Board of Trustees, and in accordance with provisions of the 1940 Act. 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 and other equity securities listed on any national or foreign exchange (excluding 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 principal market for such securities. Shares of open-end funds are valued at fair value which is based on NAV per share. Securities traded in an over-the-counter market are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price. Overnight repurchase agreements are valued at amortized cost when it represents the best estimate of fair value. Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by the Trust's Board of Trustees or its delegate, 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 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 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 type of security; 2) the size of the holding; 3) the initial cost of the security; 4) transactions in comparable securities; 5) price quotes from dealers and/or pricing services; 6) relationships among various securities; 7) information obtained by contacting the issuer, analysts, or the appropriate stock exchange; 8) an analysis of the issuer's financial statements; and 9) the existence of merger proposals or tender offers that might affect the value of the security. In addition, differences between the prices used to calculate a Fund's NAV and the prices used by such Fund's corresponding index could result in a difference between a Fund's performance and the performance of its underlying index. 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: Page 128 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2016 o 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. o 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. o 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 July 31, 2016, 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 on the accrual basis. Distributions received from a 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 is 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. OFFSETTING ON THE STATEMENTS OF ASSETS AND LIABILITIES Offsetting Assets and Liabilities requires entities to disclose both gross and net information about instruments and transactions eligible for offset on the Statements of Assets and Liabilities, and disclose instruments and transactions subject to master netting or similar agreements. These disclosure requirements are intended to help investors and other financial statement users better assess the effect or potential effect of offsetting arrangements on a fund's financial position. The transactions subject to offsetting disclosures are derivative instruments, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions. This disclosure, if applicable, is included within each Fund's Portfolio of Investments under the heading "Offsetting Assets and Liabilities". For financial reporting purposes, the Funds do not offset financial assets and financial liabilities that are subject to master netting arrangements ("MNAs") or similar agreements on the Statements of Assets and Liabilities. MNAs provide the right, in the event of default (including bankruptcy and insolvency), for the non-defaulting counterparty to liquidate the collateral and calculate the net exposure to the defaulting party or request additional collateral. D. SECURITIES LENDING The Funds may lend securities representing up to 33 1/3% of the value of their total assets to broker-dealers, banks and other institutions to generate additional income. When a Fund loans its portfolio securities, it will receive, at the inception of each loan, collateral equal to at least 102% (for domestic securities) or 105% (for international securities) of the market value of the loaned securities. The collateral amount is valued at the beginning of each business day and is compared to the market value of the loaned securities from the prior business day to determine if additional collateral is required. If additional collateral is required, a request is sent to the borrower. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund's loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of (i) a decline in the value of the collateral provided for the loaned securities, (ii) a decline in the value of any investments made with cash collateral or (iii) an increase in the value of the loaned securities if the borrower does not increase the collateral accordingly and the borrower fails to return the securities. These events could also trigger adverse tax consequences for the Funds. Under the Funds' Securities Lending Agency Agreement, the securities lending agent will generally bear the risk that a borrower may default on its obligation to return loaned securities. Brown Brothers Harriman & Co. ("BBH") acts as the Funds' securities lending agent and is responsible for executing the lending of the portfolio securities to creditworthy borrowers. The Funds, however, will be responsible for the risks associated with the investment of cash collateral. A Fund may lose money on its investment of cash collateral, which may affect its ability to repay the collateral to the borrower without the use of other Fund assets. Each Fund that engages in securities lending receives compensation (net Page 129 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2016 of any rebate and securities lending agent fees) for lending its securities. Compensation can be in the form of fees received from the securities lending agent or dividends or interest earned from the investment of cash collateral. The dividend and interest earned on the securities loaned is accounted for in the same manner as other dividend and interest income. At July 31, 2016, all the Funds except for FMK have securities in the securities lending program. In the event of a default by a borrower with respect to any loan, BBH will exercise any and all remedies provided under the applicable borrower agreement to make the Funds whole. These remedies include purchasing replacement securities by applying the collateral held from the defaulting broker against the purchase cost of the replacement securities. If, despite such efforts by BBH to exercise these remedies, a Fund sustains losses as a result of a borrower's default, BBH will indemnify the Fund by purchasing replacement securities at its own expense, or paying the Fund an amount equal to the market value of the replacement securities, subject to certain limitations which are set forth in detail in the Securities Lending Agency Agreement between the Trust on behalf of the Funds and BBH. E. REPURCHASE AGREEMENTS Repurchase agreements involve the purchase of securities subject to the seller's agreement to repurchase the securities at a mutually agreed upon date and price, under the terms of a Master Repurchase Agreement ("MRA"). During the term of a repurchase agreement, the value of the underlying securities held as collateral on behalf of a Fund, including accrued interest, is required to exceed the value of the repurchase agreement, including accrued interest. The underlying securities for all repurchase agreements are held at the Funds' custodian or designated sub-custodians under tri-party repurchase agreements. MRAs govern transactions between a Fund and select counterparties. The MRAs contain provisions for, among other things, initiation, income payments, events of default, and maintenance of collateral for repurchase agreements. Repurchase agreements received for lending securities are collateralized by U.S. Treasury Notes. The U.S. Treasury Notes are held in a joint custody account at BBH on behalf of the Funds participating in the securities lending program. In the event the counterparty defaults on the repurchase agreement, the U.S. Treasury Notes can either be maintained as part of a Fund's portfolio or sold for cash. A Fund could suffer a loss to the extent that the proceeds from the sale of the underlying collateral held by the Fund is less than the repurchase price and the Fund's costs associated with the delay and enforcement of the MRA. While the Funds may invest in repurchase agreements, any repurchase agreements held by the Funds during the fiscal year ended July 31, 2016, were received as collateral for lending securities. F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS Dividends from net investment income of each Fund, if any, are declared and paid quarterly, or as the Board of Trustees may determine from time to time. Distributions of net realized gains earned by each Fund, if any, are distributed at least annually. Distributions from income and capital gains are determined in accordance with 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 significantly modified 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, 2016, was as follows:

G. 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 the 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. Taxable years ending 2013, 2014, 2015 and 2016 remain open to federal and state audit. As of July 31, 2016, 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. Under the Regulated Investment Company Modernization Act of 2010 (the "Act"), net capital losses arising in taxable years beginning after December 22, 2010, may be carried forward indefinitely, and their character is retained as short-term and/or long-term losses. Previously, net capital losses were carried forward for up to eight years and treated as short-term losses. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses. At July 31, 2016, the Funds had pre-enactment and post-enactment net capital losses for federal income tax purposes as shown in the following table. To the extent that these loss carryforwards are used to offset future capital gains, it is probable that the capital gains so offset will not be distributed to Fund shareholders. 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.

These adjustments are primarily due to the difference between book and tax treatments of income and gains on various investment securities held by the Funds and in-kind transactions. The results of operations and net assets were not affected by these adjustments. For the fiscal year ended July 31, 2016, the adjustments for each Fund were as follows:

EXPENSES Expenses that are directly related to one of the Funds are charged directly to the respective Fund, except for the First Trust Mid Cap Value AlphaDEX(R) Fund, First Trust Mid Cap Growth AlphaDEX(R) Fund, First Trust Small Cap Value AlphaDEX(R) Fund, First Trust Small Cap Growth AlphaDEX(R) Fund and First Trust Mega Cap AlphaDEX(R) Fund (the "Unitary Fee Funds"), for which expenses other than excluded expenses (discussed in Note 3) are paid by the Advisor. General expenses of the Trust are allocated to all the Funds based upon the net assets of each Fund. Effective April 8, 2016, First Trust Portfolios L.P. ("FTP") entered into licensing agreements with Nasdaq, Inc. for each of the Style Funds. Prior to April 8, 2016, FTP had licensing agreements with Standard & Poors Financial Services LLP. The license agreements allow for the use by FTP of certain trademarks and trade names. The Funds and First Trust are sub-licensees to the applicable license agreement. The Funds, except for the Unitary Fee Funds, are required to pay licensing fees, which are shown on the Statements of Operations. The licensing fees for the Unitary Fee Funds are paid by First Trust from the unitary investment advisory fees it receives from each of these Funds. 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. For the Unitary Fee Funds, First Trust is paid an annual unitary management fee of 0.70% of such Fund's average daily net assets and is responsible for the expenses of such Fund including the cost of transfer agency, custody, fund administration, legal, audit and other services, and excluding distribution and service fees pursuant to a Rule 12b-1 plan, if any, brokerage expenses, acquired fund fees and expenses, taxes, interest, and extraordinary expenses. For the First Trust Large Cap Core AlphaDEX(R) Fund, First Trust Mid Cap Core AlphaDEX(R) Fund, First Trust Small Cap Core AlphaDEX(R) Fund, First Trust Large Cap Value AlphaDEX(R) Fund, First Trust Large Cap Growth AlphaDEX(R) Fund, First Trust Multi Cap Value AlphaDEX(R) Fund and First Trust Multi Cap Growth AlphaDEX(R) Fund, First Trust is paid an annual management fee of 0.50% of each Fund's average daily net assets. For such Funds, the Trust and First Trust have entered into an Expense Reimbursement, Fee Waiver and Recovery Agreement ("Recovery Agreement") in which First Trust has agreed to waive fees and/or reimburse Fund expenses to the extent that the operating expenses of each such Fund (excluding interest expense, brokerage commissions and other trading expenses, acquired fund fees and expenses, taxes and extraordinary expenses) exceed 0.70% of average daily net assets per year (the "Expense Cap"). These Funds will have the Expense Cap in effect until at least November 30, 2017. Expenses reimbursed and fees waived by First Trust under the Recovery Agreement are subject to recovery by First Trust for up to three years from the date the fee was waived or expense was incurred, but no reimbursement payment will be made by a Fund if it results in the Fund exceeding an expense ratio equal to the Expense Cap in place at the time the expenses were reimbursed or fees waived by First Trust. These amounts would be included in "Expenses previously waived or reimbursed" on the Statements of Operations. The advisory fee waivers and expense reimbursements for the fiscal year ended July 31, 2016 and fees waived or expenses borne by First Trust subject to recovery from the applicable Fund for the periods indicated were as follows:

At July 31, 2016, none of the Funds, other than First Trust Multi Cap Growth AlphaDEX(R) Fund, had previously waived fees or expenses reimbursed that are subject to recovery. The Trust has multiple service agreements with The Bank of New York Mellon ("BNYM"). Under the service agreements, BNYM performs custodial, fund accounting, certain administrative services, and transfer agency services for each Fund. As custodian, BNYM is responsible for custody of each Fund's assets. As fund accountant and administrator, BNYM is responsible for maintaining the books and records of each Fund's securities and cash. As transfer agent, BNYM is responsible for maintaining shareholder records for each Fund. BNYM is a subsidiary of The Bank of New York Mellon Corporation, a financial holding company. Page 133 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2016 At a meeting held on December 7, 2015, the Board of Trustees accepted Mr. Mark Bradley's resignation from his position as the President and Chief Executive Officer of the Trust, effective December 31, 2015. At the same meeting, the Board of Trustees elected Mr. James Dykas, formerly Chief Financial Officer and Treasurer of the Trust, to serve as the President and Chief Executive Officer, and Mr. Donald Swade, formerly an Assistant Treasurer of the Trust, to serve as the Treasurer, Chief Financial Officer and Chief Accounting Officer of the Trust. 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. Prior to January 1, 2016, the fixed annual retainer was allocated pro rata based on each Fund's net assets. 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 or is an index fund. Additionally, the Lead Independent Trustee and the Chairmen 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 Chairmen rotate every three years. The officers and "Interested" Trustee receive no compensation from the Trust for acting in such capacities. 4.

5. CREATION, REDEMPTION AND TRANSACTION FEES Shares are created and redeemed by each Fund only in Creation Unit size aggregations of 50,000 shares in transactions with broker-dealers or large institutional investors that have entered into a participation agreement (an "Authorized Participant"). Such transactions are generally permitted on an in-kind basis, with a balancing cash component to equate the transaction to the Page 134 -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2016 daily NAV per Share of each Fund on the transaction date times the number of Shares in a Creation Unit. Authorized Participants purchasing Creation Units must pay to BNYM, as transfer agent, a standard creation transaction fee (the "Creation Transaction Fee"), which is based on the number of different securities in a Creation Unit of each Fund according to the fee schedule set forth below: Number of Securities Creation in a Creation Unit Transaction Fee -------------------- ----------------- 1-100 $ 500 101-499 $1,000 500 or more $1,500 The Creation Transaction Fee is applicable to each purchase transaction regardless of the number of Creation Units purchased in the transaction. An additional variable fee of up to three times the Creation Transaction Fee may be charged to approximate additional expenses incurred by a Fund with respect to transactions effected outside of the clearing process (i.e., through a DTC Participant) or to the extent that cash is used in lieu of securities to purchase Creation Units. The price for each Creation Unit will equal the daily NAV per Share of a Fund on the transaction date times the number of Shares in a Creation Unit plus the fees described above and, if applicable, any transfer taxes. Authorized Participants redeeming Creation Units must pay to BNYM, as transfer agent, a standard redemption transaction fee (the "Redemption Transaction Fee"), which is based on the number of different securities in a Creation Unit of each Fund according to the fee schedule set forth below: Number of Securities Redemption in a Creation Unit Transaction Fee -------------------- ----------------- 1-100 $ 500 101-499 $1,000 500 or more $1,500 The Redemption Transaction Fee is applicable to each redemption transaction regardless of the number of Creation Units redeemed in the transaction. An additional variable fee of up to three times the Redemption Transaction Fee may be charged to approximate additional expenses incurred by a Fund with respect to redemptions effected outside of the clearing process or to the extent that redemptions are for cash. Each Fund reserves the right to effect redemptions in cash. A shareholder may request cash redemption in lieu of securities; however, a Fund may, in its discretion, reject any such request. 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 Funds are authorized to pay an amount up to 0.25% of their average daily net assets each year to reimburse FTP, the distributor of the Funds, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or the provision of 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 June 30, 2017. 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 on 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.

These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Funds are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Funds' internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of July 31, 2016 by correspondence with the Funds' custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of each of the funds listed above included in the First Trust Exchange-Traded AlphaDEX(R) Fund as of July 31, 2016, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. /s/ Deloitte & Touche LLP Chicago, Illinois September 22, 2016 Page 136 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2016 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 its 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 the Funds' website located at http://www.ftportfolios.com; and (3) on the Securities and Exchange Commission's ("SEC") website at http://www.sec.gov.

YOU SHOULD CONSIDER EACH FUND'S INVESTMENT OBJECTIVE, RISKS, CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. YOU CAN DOWNLOAD EACH FUND'S PROSPECTUS AT HTTP://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. FOR ADDITIONAL INFORMATION ABOUT THE RISKS ASSOCIATED WITH INVESTING IN THE FUNDS, PLEASE SEE THE FUNDS' STATEMENT OF ADDITIONAL INFORMATION, AS WELL AS OTHER REGULATORY FILINGS. READ THESE DOCUMENTS CAREFULLY BEFORE YOU INVEST. FIRST TRUST PORTFOLIOS L.P. IS THE DISTRIBUTOR OF THE FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND. The following summarizes some of the risks that should be considered for the Funds. CONSUMER DISCRETIONARY COMPANIES RISK. Certain of the Funds invest in consumer discretionary companies. Consumer discretionary companies are companies that provide non-essential goods and services, such as retailers, media companies and consumer services. These companies manufacture products and provide discretionary services directly to the consumer, and the success of these companies is tied closely to the performance of the overall domestic and international economy, interest rates, competition and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer discretionary products in the marketplace. ENERGY COMPANIES RISK. Certain of the Funds invest in energy companies. Energy companies include integrated oil companies that are involved in the exploration, production and refining process, gas distributors and pipeline-related companies and other energy companies involved with mining, producing and delivering energy-related services and drilling. General problems of energy companies include volatile fluctuations in price and supply of energy fuels, international politics, terrorist attacks, reduced demand, the success of exploration projects, clean-up and litigation costs relating to oil spills and environmental damage, and tax and other regulatory policies of various governments. Natural disasters such as hurricanes in the Gulf of Mexico also impact the petroleum industry. Oil production and refining companies are subject to extensive federal, state and local environmental laws and regulations regarding air emissions and the disposal of hazardous materials. In addition, oil prices are generally subject to extreme volatility. EQUITY SECURITIES RISK. Because the Funds invest in equity securities, the value of the Funds' shares will fluctuate with changes in the value of these 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. FINANCIAL COMPANIES RISK. Financial companies are especially subject to the adverse effects of economic recession, currency exchange rates, government regulation, decreases in the availability of capital, volatile interest rates, portfolio concentrations in geographic markets and in commercial residential and real estate loans, and competition from new entrants in their fields of business. GROWTH STOCKS INVESTMENT RISK. Certain of the Funds utilize a growth stocks investment strategy and are thus subject to growth stocks investment risk. Growth stocks tend to be more volatile than certain other types of stocks and their prices usually fluctuate more dramatically than the overall stock market. A stock with growth characteristics can have sharp price declines due to decreases in current or expected earnings. HEALTH CARE COMPANIES RISK. Certain of the Funds invest in health care companies. Health care companies are companies involved in medical services or health care, including biotechnology research and production, drugs and pharmaceuticals and health care facilities and services. These companies are subject to extensive competition, generic drug sales or the loss of patent protection, product liability litigation and increased government regulation. Research and development costs of bringing new drugs to market are substantial, and there is no guarantee that the product will ever come to market. Health care facility operators may be affected by the demand for services, efforts by government or insurers to limit rates, restriction of government financial assistance and competition from other providers. INDEX CONSTITUENT RISK. One or more of the Funds may be a constituent of one or more indices. As a result, the Fund may be included in one or more index-tracking ETFs or mutual funds. Being a component security of such a vehicle could greatly affect the trading activity involving the Fund, the size of the Fund and the market volatility of the Fund. Inclusion in an index could significantly 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, the Fund's NAV could be negatively impacted and the Fund's market price may be significantly below the Fund's net asset value during certain periods In addition, index rebalances may potentially result in increased trading activity. To the extent buying or selling activity increases, the Fund can be exposed to increased brokerage costs and adverse tax consequences and the market price of the Fund can be negatively affected. Page 138 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2016 INDUSTRIALS COMPANIES RISK. Industrials companies convert unfinished goods into finished durables used to manufacture other goods or provide services. These companies produce electrical equipment and components , industrial products, manufactured housing and telecommunications equipment. General risks of these companies include the general state of the economy, intense competition, consolidation, domestic and international politics, excess capacity and consumer demand and spending trends. In addition, they may also be significantly affected by overall capital spending levels, economic cycles, technical obsolescence, delays in modernization, labor relations, government regulations and e-commerce initiatives. INFORMATION TECHNOLOGY COMPANIES RISK. Certain of the Funds invest in information technology companies. Information technology companies are generally subject to the following risks: rapidly changing technologies; short product life cycles; fierce competition; aggressive pricing and reduced profit margins; the loss of patent, copyright and trademark protections; cyclical market patterns; evolving industry standards; and frequent new product introductions. Information technology companies may be smaller and less experienced companies, with limited product lines, markets or financial resources and fewer experienced management or marketing personnel. Information technology company stocks, especially those which are Internet related, have experienced extreme price and volume fluctuations that are often unrelated to their operating performance. MARKET CAPITALIZATION RISK. The Funds normally invest at least 90% of their assets in common stocks that comprise the applicable Index. The securities of companies represented in the Indices generally have market capitalizations that are consistent with the name of each Index. To determine the market capitalization range of such securities, each Fund uses the current range of the applicable Index. However, the Funds will not sell a security because the security has exceeded or fallen below the current market capitalization range of the applicable Index. Because of market movement, there can be no assurance that the securities in the Funds will stay within a given market capitalization range. As a result, the Funds may be exposed to additional risk or may not give investors the opportunity to invest fully in a given market capitalization range. MARKET RISK. Market risk is the risk that a particular security owned by a Fund or shares of a Fund in general may fall in value. Securities are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Funds could decline in value or underperform other investments. NON-CORRELATION RISK. A Fund's return may not match the return of its Index for a number of reasons. For example, a Fund incurs operating expenses not applicable to its Index, and may incur costs in buying and selling securities, especially when rebalancing the Fund's portfolio holdings to reflect changes in the composition of the Index. In addition, a Fund's portfolio holdings may not exactly replicate the securities included in its Index or the ratios between the securities included in the Index. PORTFOLIO TURNOVER RISK. Certain Funds' strategies may frequently involve buying and selling portfolio securities to rebalance the Funds' exposure to various market sectors. High portfolio turnover may result in a Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause a Fund's performance to be less than you expect. REPLICATION MANAGEMENT RISK. The Funds are exposed to additional market risk due to their policy of investing principally in the securities included in the Indices. As a result of this policy, securities held by the Funds will generally not be bought or sold in response to market fluctuations. SMALLER COMPANIES RISK. Certain of the Funds invest in small and/or mid capitalization companies. Small and/or mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies. VALUE STOCKS INVESTMENT RISK. Certain of the Funds utilize a value investment strategy and thus are exposed to value investment risk. The intrinsic value of a stock with value characteristics may not be fully recognized by the market for a long time or a stock judged to be undervalued may actually be appropriately priced at a low level. NOT FDIC INSURED NOT BANK GUARANTEED MAY LOSE VALUE Page 139 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2016 REMUNERATION First Trust Advisors L.P. ("First Trust") is authorised and regulated by the U.S. Securities and Exchange Commission and is entitled to market shares of the First Trust Exchange-Traded AlphaDEX(R) Funds it manages (the "Funds") in the United Kingdom in accordance with the cooperation arrangements in Article 42 of the Alternative Investment Fund Managers Directive (the "Directive"). First Trust is required under the Directive to make disclosures in respect of remuneration. The following disclosures are made in line with First Trust's interpretation of currently available regulatory guidance on remuneration disclosures. During the year ended December 31, 2015, the amount of remuneration paid (or to be paid) by First Trust Advisors L.P. in respect of the Funds is $9,067,727. This figure is comprised of $453,849 paid (or to be paid) in fixed compensation and $8,613,878 paid (or to be paid) in variable compensation. There were a total of 13 beneficiaries of the remuneration described above. Those amounts include $5,011,396 paid (or to be paid) to senior management of First Trust Advisors L.P. and $4,056,331 paid (or to be paid) to other employees whose professional activities have a material impact on the risk profiles of First Trust Advisors L.P. or the Funds (collectively, "Code Staff"). Code Staff included in the aggregated figures disclosed above are rewarded in line with First Trust's remuneration policy (the "Remuneration Policy") which is determined and implemented by First Trust's senior management. The Remuneration Policy reflects First Trust's ethos of good governance and encapsulates the following principal objectives: i. to provide a clear link between remuneration and performance of First Trust and to avoid rewarding for failure; ii. to promote sound and effective risk management consistent with the risk profiles of the Funds managed by First Trust; and iii. to remunerate staff in line with the business strategy, objectives, values and interests of First Trust and the Funds managed by First Trust in a manner that avoids conflicts of interest. First Trust assesses various risk factors which it is exposed to when considering and implementing remuneration for Code Staff and considers whether any potential award to such person(s) would give rise to a conflict of interest. First Trust does not reward failure, or consider the taking of risk or failure to take risk in its remuneration of Code Staff. First Trust assesses performance for the purposes of determining payments in respect of performance-related remuneration of Code Staff by reference to a broad range of measures including (i) individual performance (using financial and non-financial criteria), and (ii) the overall performance of First Trust. Remuneration is not based upon the performance of the Funds. The elements of remuneration are balanced between fixed and variable and the senior management sets fixed salaries at a level sufficient to ensure that variable remuneration incentivises and rewards strong individual performance but does not encourage excessive risk taking. No individual is involved in setting his or her own remuneration. ADVISORY AGREEMENT BOARD CONSIDERATIONS REGARDING CONTINUATION OF INVESTMENT MANAGEMENT AGREEMENT The Board of Trustees (the "Board") of the First Trust Exchange-Traded AlphaDEX(R) Fund (the "Trust"), including the Independent Trustees, unanimously approved the continuation 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" or "First Trust") on behalf of the following twelve series of the Trust (each a "Fund" and collectively, the "Funds"): First Trust Large Cap Core AlphaDEX(R) Fund (FEX) First Trust Mid Cap Core AlphaDEX(R) Fund (FNX) First Trust Small Cap Core AlphaDEX(R) Fund (FYX) First Trust Multi Cap Growth AlphaDEX(R) Fund (FAD) First Trust Multi Cap Value AlphaDEX(R) Fund (FAB) First Trust Large Cap Growth AlphaDEX(R) Fund (FTC) First Trust Large Cap Value AlphaDEX(R) Fund (FTA) First Trust Mid Cap Value AlphaDEX(R) Fund (FNK) First Trust Mid Cap Growth AlphaDEX(R) Fund (FNY) First Trust Small Cap Value AlphaDEX(R) Fund (FYT) First Trust Small Cap Growth AlphaDEX(R) Fund (FYC) First Trust Mega Cap AlphaDEX(R) Fund (FMK) Page 140 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2016 The Board approved the continuation of the Agreement for each Fund for a one-year period ending June 30, 2017 at a meeting held on June 13, 2016. The Board determined for each Fund that the continuation of the Agreement is in the best interests of the Fund in light of the extent and quality of the services provided and such other matters as the Board considered to be relevant in the exercise of its reasonable business judgment. To reach this determination for each Fund, the Board considered its duties under the Investment Company Act of 1940, as amended (the "1940 Act"), as well as under the general principles of state law in reviewing and approving advisory contracts; the requirements of the 1940 Act in such matters; the fiduciary duty of investment advisors with respect to advisory agreements and compensation; the standards used by courts in determining whether investment company boards have fulfilled their duties; and the factors to be considered by the Board in voting on such agreements. At meetings held on April 22, 2016 and June 13, 2016, the Board, including the Independent Trustees, reviewed materials provided by the Advisor responding to requests for information from counsel to the Independent Trustees that, among other things, outlined the services provided by the Advisor to each Fund (including the relevant personnel responsible for these services and their experience); the advisory fee rate or unitary fee rate payable by each Fund as compared to fees charged to a peer group of funds (all of which were exchange-traded funds ("ETFs")) compiled by Management Practice, Inc. ("MPI"), an independent source (the "MPI Peer Group"), and as compared to fees charged to other clients of the Advisor, including other ETFs managed by the Advisor; expenses of each Fund as compared to expense ratios of the funds in the Fund's MPI Peer Group; performance information for each Fund; the nature of expenses incurred in providing services to each Fund and the potential for economies of scale, if any; financial data on the Advisor; any fall-out benefits to the Advisor and its affiliate, First Trust Portfolios L.P. ("FTP"); and information on the Advisor's compliance program. The Board reviewed initial materials with the Advisor at a special meeting held on April 22, 2016, prior to which the Independent Trustees and their counsel met separately to discuss the information provided by the Advisor. Following the April meeting, independent legal counsel on behalf of the Independent Trustees requested certain clarifications and supplements to the materials provided, and the information provided in response to those requests was considered at an executive session of the Independent Trustees and independent legal counsel held prior to the June 13, 2016 meeting, as well as at the meeting held that day. The Board applied its business judgment to determine whether the arrangement between the Trust and the Advisor continues to be a reasonable business arrangement from each Fund's perspective as well as from the perspective of shareholders. The Board determined that, given the totality of the information provided with respect to the Agreements, the Board had received sufficient information to renew the Agreements. The Board considered that shareholders chose to invest or remain invested in a Fund knowing that the Advisor manages the Fund and knowing the Fund's advisory fee or unitary fee. In reviewing the Agreement for each Fund, the Board considered the nature, extent and quality of the services provided by the Advisor under the Agreement. The Board considered that the Advisor is responsible for the overall management and administration of the Trust and each Fund and reviewed all of the services provided by the Advisor to the Funds, as well as the background and experience of the persons responsible for such services. In reviewing the services provided, the Board noted the compliance program that had been developed by the Advisor and considered that it includes a robust program for monitoring the Advisor's and each Fund's compliance with the 1940 Act, as well as each Fund's compliance with its investment objective and policies. In addition, as part of the Board's consideration of the Advisor's services, the Advisor, in its written materials and at the April 22, 2016 meeting, described to the Board the scope of its ongoing investment in additional infrastructure and personnel to maintain and improve the quality of services provided to the Funds and the other funds in the First Trust Fund Complex. In light of the information presented and the considerations made, the Board concluded that the nature, extent and quality of the services provided to the Trust and each Fund by the Advisor under the Agreements have been and are expected to remain satisfactory and that the Advisor has managed each Fund consistent with the Fund's investment objective and policies. For FEX, FNX, FYX, FAD, FAB, FTC and FTA (the "Non-Unitary Fee Funds"), the Board considered the advisory fee rate payable by each Non-Unitary Fee Fund under the applicable Agreement for the services provided. The Board considered that the Advisor agreed to extend the current expense cap for each Non-Unitary Fee Fund through November 30, 2017. For each Non-Unitary Fee Fund, the Board noted that expenses borne or fees waived by the Advisor are to be subject to reimbursement by the Non-Unitary Fee Fund for up to three years from the date the expense was incurred or fee was waived, but no reimbursement payment would be made by the Non-Unitary Fee Fund if it would result in the Non-Unitary Fee Fund exceeding an expense ratio equal to the expense cap in place at the time the expenses were borne or fees were waived by the Advisor. For FNK, FNY, FYT, FYC and FMK (the "Unitary Fee Funds"), the Board considered the unitary fee rate payable by each Unitary Fee Fund under the applicable Agreement for the services provided. The Board considered that, as part of the unitary fee, the Advisor is responsible for each Unitary Fee Fund's expenses, including the cost of transfer agency, custody, fund administration, legal, audit, licensing and other services, but excluding interest, taxes, 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. The Board received and reviewed information showing the advisory or unitary fee rates and expense ratios of the peer funds in the MPI Peer Groups, as well as advisory fee and unitary fee rates charged by the Advisor to other fund (including ETFs) and non-fund clients. Because each Fund's MPI Peer Group included peer funds that pay a unitary fee and because the Unitary Fee Funds pay a unitary fee, the Board determined that expense ratios were the most relevant comparative data point. Based on the information provided, the Board noted that Page 141 -------------------------------------------------------------------------------- ADDITIONAL INFORMATION (CONTINUED) -------------------------------------------------------------------------------- FIRST TRUST EXCHANGE-TRADED ALPHADEX(R) FUND STYLE FUNDS JULY 31, 2016 the total (net) expense ratio of each Non-Unitary Fee Fund and the unitary fee for each Unitary Fee Fund was above the median total (net) expense ratio of the peer funds in each Fund's respective MPI Peer Group. With respect to the MPI Peer Groups, the Board discussed with representatives of the Advisor limitations in creating peer groups for index ETFs, including differences in underlying indexes and index-tracking methodologies that can result in greater management complexities across seemingly comparable ETFs, and different business models that may affect the pricing of services among ETF sponsors. The Board took these limitations and differences into account in considering the peer data. With respect to fees charged to other clients, the Board considered differences between the Funds and other clients that limited their comparability. In considering the advisory and unitary fee rates overall, the Board also considered the Advisor's statement that it seeks to meet investor needs through innovative and value-added investment solutions and the Advisor's description of its long-term commitment to each Fund. The Board considered performance information for each Fund. The Board noted the process it has established for monitoring each Fund's performance and portfolio risk on an ongoing basis, which includes quarterly performance reporting from the Advisor for the Funds. The Board determined that this process continues to be effective for reviewing each Fund's performance. The Board received and reviewed information for periods ended December 31, 2015 regarding the performance of each Fund's underlying index, the correlation between each Fund's performance and that of its underlying index, each Fund's tracking difference and each Fund's excess return as compared to its benchmark index. The Board considered the Advisor's explanations of how the AlphaDEX(R) stock selection methodology impacts Fund performance in various market environments, and the Advisor's statement that AlphaDEX(R) is designed to provide long-term outperformance. Based on the information provided and its ongoing review of performance, the Board concluded that each Fund was correlated to its underlying index and that the tracking difference for each Fund was consistent with the Fund's prospectus. The Board noted that effective April 8, 2016, each Fund changed its underlying index to an index developed and maintained by Nasdaq, Inc. using the AlphaDEX stock selection methodology. In addition, the Board reviewed data prepared by MPI comparing each Fund's performance to its respective MPI Peer Group and to one or more broad-based benchmark indexes, but given each Fund's objective of seeking investment results that correspond generally to the performance of its underlying index, the Board placed more emphasis on its review of correlation and tracking difference. On the basis of all the information provided on the fees, expenses and performance of each Fund and the ongoing oversight by the Board, the Board concluded that the advisory fee and unitary fee for each Fund continues to be reasonable and appropriate in light of the nature, extent and quality of the services provided by the Advisor to each Fund under the Agreements. The Board considered information and discussed with the Advisor whether there were any economies of scale in connection with providing advisory services to the Funds and noted the Advisor's statement that it expects its expenses to increase over the next twelve months as the Advisor continues to make investments in personnel and infrastructure. For the Unitary Fee Funds, the Board noted that any reduction in fixed costs associated with the management of the Unitary Fee Funds would benefit the Advisor, but that the unitary fee structure provides a level of certainty in expenses for the Unitary Fee Funds. The Board considered the revenues and allocated costs (including the allocation methodology) of the Advisor in serving as investment advisor to each Fund for the twelve months ended December 31, 2015 and the estimated profitability level for each Fund calculated by the Advisor based on such data, as well as complex-wide and product-line profitability data for the same period. The Board noted the inherent limitations in the profitability analysis, and concluded that, based on the information provided, the Advisor's profitability level for each Fund was not unreasonable. The Board considered that the Advisor had identified as a fall-out benefit to the Advisor and FTP their exposure to investors and brokers who, absent their exposure to the Funds, may have had no dealings with the Advisor or FTP, and noted that the Advisor does not utilize soft dollars in connection with its management of the Funds' portfolios. Based on all of the information considered and the conclusions reached, the Board, including the Independent Trustees, unanimously determined that the terms of the Agreements continue to be fair and reasonable and that the continuation of the Agreements is in the best interests of the Trust and each Fund. No single factor was determinative in the Board's analysis.

Pursuant to its charter and its Audit and Non-Audit Services Pre-Approval Policy, the Audit Committee (the "Committee") is responsible for the pre-approval of all audit services and permitted non-audit services (including the fees and terms thereof) to be performed for the registrant by its independent auditors. The Chairman of the Committee is authorized to give such pre-approvals on behalf of the Committee up to $25,000 and report any such pre-approval to the full Committee. The Committee is also responsible for the pre-approval of the independent auditor's engagements for non-audit services with the registrant's adviser (not including a sub-adviser whose role is primarily portfolio management and is sub-contracted or overseen by another investment adviser) and any entity controlling, controlled by or under common control with the investment adviser that provides ongoing services to the registrant, if the engagement relates directly to the operations and financial reporting of the registrant, subject to the de minimis exceptions for non-audit services described in Rule 2-01 of Regulation S-X. If the independent auditor has provided non-audit services to the registrant's adviser (other than any sub-adviser whose role is primarily portfolio management and is sub-contracted with or overseen by another investment adviser) and any entity controlling, controlled by or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to its policies, the Committee will consider whether the provision of such non-audit services is compatible with the auditor's independence. (e)(2) The percentage of services described in each of paragraphs (b) through (d) for the registrant and the registrant's investment adviser and distributor of this Item that were approved by the audit committee pursuant to the pre-approval exceptions included in paragraph (c)(7)(i)(C) or paragraph(C)(7)(ii) of Rule 2-01 of Regulation S-X are as follows: Registrant: Adviser and Distributor: ----------- ------------------------ (b) 0% (b) 0% (c) 0% (c) 0% (d) 0% (d) 0% (f) The percentage of hours expended on the principal accountant's engagement to audit the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons other than the principal accountant's full-time, permanent employees was less than fifty percent.
