First Quarter and Full Year 2024 Guidance

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 on the date of this press release. 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, including our outlook and guidance, our operating performance, our ability to innovate, our customer acquisition and go-to-market efforts, our ability to monetize, and our ability to deliver on our long-term strategy. 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, 2023. Additional information will also be set forth in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Use of Non-GAAP Financial Measures

To supplement our condensed 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 income (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 acquired intangible assets, acquisition-related expenses, executive transition costs, net gain on extinguishment of debt, impairment expense and amortization of debt discount and issuance costs.

Adjusted EBITDA: excludes stock-based compensation expense, depreciation and other amortization expenses, amortization of acquired intangible assets, acquisition-related expenses, executive transition costs, interest income, interest expense, including amortization of debt discount and issuance costs, net gain on extinguishment of debt, impairment expense, other income (expense), net, and income taxes.

Acquisition-Related Expenses: consists of acquisition-related charges that are not related to ongoing operations. Management considers its operating results without this activity when evaluating its ongoing non-GAAP net income (loss) performance and its adjusted EBITDA performance because these charges may not be reflective of our core business, ongoing operating results, or future outlook.

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 and non-cash charges recognized with respect to changes in our executives' 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.

Impairment Expense: consists of impairment charge related to our computer and networking equipment, including software, we expect to not be used. 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 Income (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.

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.

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.

Key Metrics

¹ We calculate LTM Net Retention Rate by dividing the total customer revenue for the prior twelve-month period (“prior 12-month period”) ending at the beginning of the last twelve-month period (“LTM period”) minus revenue contraction due to billing decreases or customer churn, plus revenue expansion due to billing increases during the LTM period from the same customers by the total prior 12-month period revenue. We believe the LTM Net Retention Rate is supplemental as it removes some of the volatility that is inherent in a usage-based business model.

² Under our new methodology, our number of customers is calculated based on the number of separate identifiable operating entities with which we have a billing relationship in good standing, from which we recognized revenue during the current quarter. Under our prior methodology, our number of customers is calculated based on the number of separate identifiable operating entities with which we have a billing relationship in good standing, from which we recognized revenue during the last month of the quarter. Under our new methodology, our enterprise customers are defined as those with annualized current quarter revenue in excess of $100,000. This is calculated by taking the revenue for each customer within the quarter and multiplying it by four. Under our prior methodology, our enterprise customers are defined as those with revenue in excess of $100,000 in the trailing 12-month period. Under our prior methodology, our total customer count was 3,097 in the fourth quarter, up 78 from the third quarter of 2023; 532 were enterprise customers in the fourth quarter, up 2 from the third quarter of 2023.

³ Under our new methodology, our average enterprise customer spend is calculated by taking the annualized current quarter revenue contributed by enterprise customers existing as of the current period, and dividing that by the number of enterprise customers as of the current period. Under our prior methodology, our average enterprise customer spend is calculated by taking the sum of the trailing 12-month revenue contributed by enterprise customers existing as of the current period, and dividing that by the number of enterprise customers as of the current period. Under our prior methodology, our average enterprise customer spend was $859 thousand in the fourth quarter, up 3% quarter-over-quarter.

⁴ Remaining performance obligations include future committed revenue for periods within current contracts with customers, as well as deferred revenue arising from consideration invoiced for which the related performance obligations have not been satisfied.

⁵ Non-GAAP net income (loss) per basic share is calculated as Non-GAAP net income (loss) divided by weighted average basic shares for 2024.

⁶ Assumes weighted average basic shares outstanding of 134.3 million in Q1 2024 and 137.5 million for the full year 2024.

⁷ Annual Revenue Retention rate is calculated by first calculating "Annual Revenue Churn", which is calculated by multiplying the final full month of revenue from a customer that terminated its contract with us, (a "Churned Customer") by the number of months remaining in the same calendar year. Our ARR rate is calculated by subtracting the quotient of the Annual Revenue Churn from all of our Churned Customers from which we recognized revenue during the last quarter of the prior year divided by our annual revenue of the same calendar year from 100%. Under the prior methodology, our ARR rate is calculated by subtracting the quotient of the Annual Revenue Churn from all of our Churned Customers from which we recognized revenue during the last month of the prior year divided by our annual revenue of the same calendar year from 100%. Under our prior methodology, our ARR was 99.1%, down 0.1% year-over-year.
