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 and cannot be reasonably determined or predicted at this time, although it is important to note that these factors could be material to Fastly’s future GAAP financial results.

This press release contains “forward-looking” statements that are based on our beliefs and assumptions and on information currently available to us. Forward-looking statements may involve known and unknown risks, uncertainties, and other factors that may cause our actual results, performance, or achievements to be materially different from those expressed or implied by the forward-looking statements. These statements include, but are not limited to, statements regarding our future financial and operating performance and shareholder returns, including our outlook and guidance and ability to improve liquidity; our ability to acquire new customers, expand cross-sell opportunities, and grow market share; our ability to enrich our revenue mix with platform enhancements; the performance of our existing and new platform enhancements; the performance, capabilities, and expectations regarding customer experiences with API Inventory, AI Assistant, Custom Dashboards and alerts, and the Adaptive Threat Engine update for Fastly DDoS Protection; and Fastly's strategies, platform, and business plans. Except as required by law, we assume no obligation to update these forward-looking statements publicly or to update the reasons actual results could differ materially from those anticipated in the forward-looking statements, even if new information becomes available in the future. Important factors that could cause our actual results to differ materially are detailed from time to time in the reports Fastly files with the Securities and Exchange Commission (“SEC”), including in our Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2025. Additional information will also be set forth in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

Use of Non-GAAP Financial Measures

To supplement our consolidated financial statements, which are prepared and presented in accordance with accounting principles generally accepted in the United States (“GAAP”), the Company uses the following non-GAAP measures of financial performance: non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating loss, non-GAAP net income (loss), non-GAAP basic and diluted net income (loss) per common share, non-GAAP research and development, non-GAAP sales and marketing, non-GAAP general and administrative, free cash flow and adjusted EBITDA. The presentation of this additional financial information is not intended to be considered in isolation from, as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. These non-GAAP measures have limitations in that they do not reflect all of the amounts associated with our results of operations as determined in accordance with GAAP. In addition, these non-GAAP financial measures may be different from the non-GAAP financial measures used by other companies. These non-GAAP measures should only be used to evaluate our results of operations in conjunction with the corresponding GAAP measures. Management compensates for these limitations by reconciling these non-GAAP financial measures to the most comparable GAAP financial measures within our earnings releases.

Non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating loss, non-GAAP net income (loss) and non-GAAP basic and diluted net loss per common share, non-GAAP research and development, non-GAAP sales and marketing, and non-GAAP general and administrative differ from GAAP in that they exclude stock-based compensation expense, amortization of capitalized stock-based compensation - cost of revenue, amortization of acquired intangible assets, and amortization of debt discount and issuance costs.

Adjusted EBITDA: excludes stock-based compensation expense, amortization of capitalized stock-based compensation - cost of revenue, gain on modification of lease, depreciation and other amortization expenses, amortization of acquired intangible assets, impairment expense, executive transition costs, restructuring charges, interest income, interest expense, including amortization of debt discount and issuance costs, other expense, net, and income taxes.

Amortization of Acquired Intangible Assets: consists of non-cash charges that can be affected by the timing and magnitude of asset purchases and acquisitions. Management considers its operating results without this activity when evaluating its ongoing non-GAAP performance and its adjusted EBITDA performance because these charges are non-cash expenses that can be affected by the timing and magnitude of asset purchases and acquisitions and may not be reflective of our core business, ongoing operating results, or future outlook.

Amortization of Debt Discount and Issuance Costs: consists primarily of amortization expense related to our debt obligations. Management considers its operating results without this activity when evaluating its ongoing non-GAAP net income (loss) performance and its adjusted EBITDA performance because it is not believed by management to be reflective of our core business, ongoing operating results or future outlook. These are included in our total interest expense.

Capital Expenditures: consists of cash used for purchases of property and equipment, net of proceeds from sale of property and equipment, capitalized internal-use software and payments on finance lease obligations, as reflected in our statement of cash flows.

Depreciation and Other Amortization Expense: consists of non-cash charges that can be affected by the timing and magnitude of asset purchases. Management considers its operating results without this activity when evaluating its ongoing adjusted EBITDA performance because these charges are non-cash expenses that can be affected by the timing and magnitude of asset purchases and may not be reflective of our core business, ongoing operating results, or future outlook.

Executive Transition Costs: consists of one-time cash charges recognized with respect to changes in our executive’s employment status. Management considers its operating results without this activity when evaluating its ongoing non-GAAP net income (loss) performance and its adjusted EBITDA performance because it is not believed by management to be reflective of our core business, ongoing operating results, or future outlook.

Free Cash Flow: calculated as net cash used in operating activities less purchases of property and equipment, net of proceeds from sale of property and equipment, principal payments of finance lease liabilities, capitalized internal-use software costs and advance payments made related to capital expenditures. Management specifically identifies adjusting items in the reconciliation of GAAP to non-GAAP financial measures. Management considers non-GAAP free cash flow to be a profitability and liquidity measure that provides useful information to management and investors about the amount of cash generated by the business that can possibly be used for investing in Fastly's business and strengthening its balance sheet, but it is not intended to represent the residual cash flow available for discretionary expenditures. The presentation of non-GAAP free cash flow is also not meant to be considered in isolation or as an alternative to cash flows from operating activities as a measure of liquidity.

Gain on Modification of Lease: consists of a one-time non-cash charge recognized with respect to the modification of our leases. Management considers its operating results without this activity when evaluating its ongoing non-GAAP net income (loss) performance and its adjusted EBITDA performance because it is not believed by management to be reflective of our core business, ongoing operating results, or future outlook.

Impairment Expense: consists of charges related to our long-lived assets. Management considers its operating results without this activity when evaluating its ongoing non-GAAP net income (loss) performance and its adjusted EBITDA performance because it is not believed by management to be reflective of our core business, ongoing operating results or future outlook.

Income Taxes: consists primarily of expenses recognized related to state and foreign income taxes. Management considers its operating results without this activity when evaluating its ongoing adjusted EBITDA performance because it is not believed by management to be reflective of our core business, ongoing operating results or future outlook.

Interest Expense: consists primarily of interest expense related to our debt instruments, including amortization of debt discount and issuance costs. Management considers its operating results without this activity when evaluating its ongoing non-GAAP net income (loss) performance and its adjusted EBITDA performance because it is not believed by management to be reflective of our core business, ongoing operating results or future outlook.

Interest Income: consists primarily of interest income related to our marketable securities. Management considers its operating results without this activity when evaluating its ongoing non-GAAP net income (loss) performance and its adjusted EBITDA performance because it is not believed by management to be reflective of our core business, ongoing operating results or future outlook.

Net Gain on Debt Extinguishment: relates to net gain on the partial repurchase of our outstanding convertible debt. Management considers its operating results without this activity when evaluating its ongoing non-GAAP net income (loss) performance and its adjusted EBITDA performance because it is not believed by management to be reflective of our core business, ongoing operating results or future outlook.

Other Expense, Net: consists primarily of foreign currency transaction gains and losses. Management considers its operating results without this activity when evaluating its ongoing adjusted EBITDA performance because it is not believed by management to be reflective of our core business, ongoing operating results or future outlook.

Restructuring Charges: consists primarily of employee-related severance and termination benefits related to management's restructuring plan that resulted in a reduction in our workforce. Management considers its operating results without this activity when evaluating its ongoing non-GAAP net income (loss) performance and its adjusted EBITDA performance because it is not believed by management to be reflective of our core business, ongoing operating results or future outlook.

Stock-Based Compensation Expense: consists of expenses for stock options, restricted stock units, performance awards, restricted stock awards and Employee Stock Purchase Plan ("ESPP") under our equity incentive plans. Although stock-based compensation is an expense for the Company and is viewed as a form of compensation, management considers its operating results without this activity when evaluating its ongoing non-GAAP net income (loss) performance and its adjusted EBITDA performance, primarily because it is a non-cash expense not believed by management to be reflective of our core business, ongoing operating results, or future outlook. In addition, the value of some stock-based instruments is determined using formulas that incorporate variables, such as market volatility, that are beyond our control.

Amortization of Capitalized Stock-Based Compensation - Cost of Revenue: in order to reflect the performance of our core business, ongoing operating results, or future outlook, and to be consistent with the way many investors evaluate our performance and compare our operating results to peer companies, similar to stock-based compensation, management considers it appropriate to exclude amortization of capitalized stock-based compensation from our non-GAAP financial measures.

Management believes these non-GAAP financial measures and adjusted EBITDA serve as useful metrics for our management and investors because they enable a better understanding of the long-term performance of our core business and facilitate comparisons of our operating results over multiple periods and to those of peer companies, and when taken together with the corresponding GAAP financial measures and our reconciliations, enhance investors' overall understanding of our current financial performance.

In the financial tables below, the Company provides a reconciliation of the most comparable GAAP financial measure to the historical non-GAAP financial measures used in this press release.
