Other Upcoming Events:

Cloudflare Lock-up Expiration: In connection with our initial public offering of Class A common stock, all of our executive officers, directors, and stockholders as of the IPO were parties to market standoff agreements with us or entered into lock-up agreements with the IPO underwriters that restrict their ability to sell or transfer their Cloudflare shares (the “lock-up”). Pursuant to the lock-up agreements, if (i) at least 120 days have elapsed since September 12, 2019, (ii) we have publicly released earnings results for the fiscal year ended December 31, 2019, and (iii) the lock-up is scheduled to end during or within five trading days prior to a broadly applicable period during which trading in our securities would not be permitted under our insider trading policy (the “blackout period”), then the lock-up will end up to ten trading days prior to the commencement of the blackout period; so long as we have publicly announced the lock-up expiration at least two trading days in advance of such expiration.

The lock-up is scheduled to end on March 11, 2020, which falls within the quarterly blackout period under our insider trading policy that commences on March 1, 2020. Therefore, in accordance with the lock-up agreements, the lock-up will end at the beginning of trading on February 19, 2020. We will also release all of our market standoff agreements when the lock-up expires.

Explanation of Non-GAAP Financial Measures

In addition to our results determined in accordance with generally accepted accounting principles in the United States (U.S. GAAP), we believe the following non-GAAP measures are useful in evaluating our operating performance. We use the following non-GAAP financial information to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance. However, non-GAAP financial information has limitations as an analytical tool and should not be considered in isolation or as a substitute for financial information presented in accordance with U.S. GAAP. In particular, free cash flow is not a substitute for cash provided by (used in) operating activities. Additionally, the utility of free cash flow as a measure of our liquidity is further limited as it does not represent the total increase or decrease in our cash balance for a given period. In addition, other companies, including companies in our industry, may calculate similarly-titled non-GAAP measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. A reconciliation is provided above for each non-GAAP financial measure to the most directly comparable financial measure stated in accordance with U.S. GAAP. Investors are cautioned that there are a number of limitations associated with the use of non-GAAP financial measures as analytical tools. Investors are encouraged to review the related U.S. GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable U.S. GAAP financial measures, and not to rely on any single financial measure to evaluate our business.

Expenses Excluded from Non-GAAP Measures. We exclude stock-based compensation expense, which is a non-cash expense, from certain of our non-GAAP financial measures because we believe that excluding this item provides meaningful supplemental information regarding operational performance. We exclude amortization of intangible assets, which is a non-cash expense, related to business combinations from certain of our non-GAAP financial measures because such expenses are related to business combinations and have no direct correlation to the operation of our business.

Non-GAAP Gross Profit and Non-GAAP Gross Margin. We define non-GAAP gross profit and non-GAAP gross margin as U.S. GAAP gross profit and U.S. GAAP gross margin, respectively, excluding stock-based compensation expense and amortization of acquired intangible assets.

Non-GAAP Loss from Operations and Non-GAAP Operating Margin. We define non-GAAP loss from operations and non-GAAP operating margin as U.S. GAAP loss from operations and U.S. GAAP operating margin, respectively, excluding stock-based compensation expense and amortization of acquired intangible assets.

Non-GAAP Net Loss and Non-GAAP Net Loss per Share, Basic and Diluted. We define non-GAAP net loss as GAAP net loss plus stock-based compensation expense, amortization of acquired intangible assets, and a non-GAAP provision for (benefit from) income taxes. The difference between our GAAP and non-GAAP income tax expense (benefit) is primarily due to adjustments in stock-based compensation and amortization of intangibles associated with business combinations. We define non-GAAP net loss per share, basic and diluted, as non-GAAP net loss divided by the weighted-average common shares outstanding. Since we have reported net losses for all periods presented, we have excluded all potentially dilutive securities from the calculation of net loss per share as their effect is antidilutive and accordingly, basic and diluted net loss per share is the same for all periods presented. We believe that excluding these items from non-GAAP net loss and non-GAAP net loss per share, diluted, provides management and investors with greater visibility into the underlying performance of our core business operating results.

Free Cash Flow and Free Cash Flow Margin. Free cash flow is a non-GAAP financial measure that we calculate as net cash provided by (used in) operating activities less cash used for purchases of property and equipment and capitalized internal-use software. Free cash flow margin is calculated as free cash flow divided by revenue. We believe that free cash flow and free cash flow margin are useful indicators of liquidity that provide information to management and investors about the amount of cash generated from our operations that, after the investments in property and equipment and capitalized internal-use software, can be used for strategic initiatives, including investing in our business, and strengthening our financial position. We believe that historical and future trends in free cash flow and free cash flow margin, even if negative, provide useful information about the amount of cash generated (or consumed) by our operating activities that is available (or not available) to be used for strategic initiatives. For example, if free cash flow is negative, we may need to access cash reserves or other sources of capital to invest in strategic initiatives. One limitation of free cash flow and free cash flow margin is that these measures do not reflect our future contractual commitments. Additionally, free cash flow does not represent the total increase or decrease in our cash balance for a given period.
