Innovation is the energy that fuels Cloudflare, differentiates us in the market, and enables us to help build a better Internet.”

The section titled "Non-GAAP Financial Information" below describes our usage of non-GAAP financial measures. Reconciliations between historical GAAP and non-GAAP information are contained at the end of this press release following the accompanying financial data.

Financial Outlook

The following forward-looking statements regarding our financial outlook are subject to substantial uncertainty as a result of the COVID-19 pandemic, reflect our estimates as of February 11, 2021 regarding the impact of the pandemic on our operations, and are highly dependent on numerous factors that we may not be able to predict or control, including, among others: the duration, spread, and severity of the pandemic; actions taken by governments and businesses in response to the pandemic and the resulting impact on our customers, vendors, and partners; the impact of the pandemic on global and regional economies and economic activity generally; our ability to continue operating in impacted areas; and customer demand and spending patterns.

For the first quarter of 2021, we expect:

Total revenue of $130 to $131 million
Non-GAAP loss from operations of $9 to $8 million
Non-GAAP net loss per share of $0.03 to $0.02, utilizing weighted average common shares outstanding of approximately 306 million

For the full year 2021, we expect:

Total revenue of $589 to $593 million
Non-GAAP loss from operations of $25 to $21 million
Non-GAAP net loss per share of $0.09 to $0.08, utilizing weighted average common shares outstanding of approximately 309 million

Interested parties can access the call by dialing (866) 211-4146 from the United States or (647) 689-6734 internationally with conference ID 2367983.

Supplemental Financial and Other Information

Supplemental financial and other information can be accessed through the Company’s investor relations website at https://cloudflare.NET. Beginning with the quarter ended March 31, 2020, we have transitioned the method for calculating our key business metrics from a billings-based methodology to a revenue-based methodology. We believe the change in methodology to GAAP-based metrics provides improved disclosures for our investors by better aligning our key business metrics with GAAP and our financial statements and will provide a better representation of these important components of our operating model and business performance as we continue to scale. We have recast these metrics for the historical period prior to March 31, 2020 to reflect this new methodology in our supplemental materials.

Non-GAAP Financial Information

Cloudflare believes that the presentation of non-GAAP financial information provides important supplemental information to management and investors regarding financial and business trends relating to the Company’s financial condition and results of operations. Reconciliations of non-GAAP financial measures to the most directly comparable financial results as determined in accordance with GAAP are included at the end of this press release following the accompanying financial data. A reconciliation of non-GAAP guidance measures to corresponding GAAP measures is not available on a forward-looking basis without unreasonable effort due to the uncertainty of expenses that may be incurred in the future. For further information regarding why Cloudflare believes that these non-GAAP measures provide useful information to investors, the specific manner in which management uses these measures, and some of the limitations associated with the use of these measures, please refer to the “Explanation of Non-GAAP Financial Measures” section at the end of this press release.

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 is presented for supplemental informational purposes only, 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 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 employer payroll tax expenses related to stock-based compensation which is a cash expense, from certain of our non-GAAP financial measures because such expenses are dependent on the price of our common stock and other factors that are beyond our control and do not correlate to the operation of our business. Employer payroll tax expenses related to stock-based compensation was not material for all previous periods presented, and therefore it was not excluded from periods prior to March 31, 2020. We exclude amortization of acquired 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. We exclude acquisition-related and other expenses 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. Acquisition-related and other expenses can be cash or non-cash expenses and include third-party transaction costs and compensation expense for key acquired personnel. We exclude amortization of debt discount and issuance costs, which is a non-cash expense, from certain of our non-GAAP financial measures because such expenses 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 and related employer payroll taxes 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 and related employer payroll taxes, amortization of acquired intangible assets, and acquisition-related and other expenses.

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 and related employer payroll taxes, amortization of acquired intangible assets, acquisition-related and other expenses, and a non-GAAP provision for (benefit from) income taxes. Generally, the difference between our GAAP and non-GAAP income tax expense (benefit) is primarily due to adjustments in stock-based compensation and related employer payroll taxes, amortization of acquired intangibles associated with business combinations, acquisition-related and other expenses, and amortization of debt discount and issuance costs. 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 they 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.
