Financial Outlook

For the first quarter of 2025, we expect:

• Revenue between $1.93 billion to $1.97 billion;
• Non-GAAP gross margin of approximately 63%; and
• Non-GAAP operating margin of approximately 44%.

Guidance for non-GAAP financial measures excludes certain items, including stock-based compensation expense, intangible asset amortization, and potential non-recurring charges or benefits. A reconciliation of non-GAAP guidance measures to corresponding GAAP measures is not available on a forward-looking basis without unreasonable effort because these exclusions can be uncertain or difficult to predict, including stock-based compensation expense which is impacted by the timing of employee stock transactions, the company's future hiring and retention needs and the future fair market value of the company's common stock. The actual amount of these exclusions will have a significant impact on the company's GAAP gross margin and GAAP operating margin.

Non-GAAP Financial Measures

This press release and accompanying table contain certain non-GAAP financial measures including non-GAAP gross profit, non-GAAP gross margin, non-GAAP income from operations, non-GAAP operating margin, non-GAAP net income and non-GAAP diluted net income per share. These non-GAAP financial measures exclude stock-based compensation expense, intangible asset amortization, expenses related to legal settlement, gains/losses on strategic investments, and the income tax effect of these non-GAAP exclusions. In addition, non-GAAP financial measures exclude net tax benefits associated with stock-based awards, which include excess tax benefits, and other discrete indirect effects of such awards. The company uses these non-GAAP financial measures internally in analyzing its financial results and believes that these non-GAAP financial measures are useful to investors as an additional tool to evaluate ongoing operating results and trends. In addition, these measures are the primary indicators management uses as a basis for its planning and forecasting for future periods.

Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for the comparable GAAP financial measures. Non-GAAP financial measures are subject to limitations, and should be read only in conjunction with the company's consolidated financial statements prepared in accordance with GAAP. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similarly titled measures presented by other companies. A description of these non-GAAP financial measures and a reconciliation of the company's non-GAAP financial measures to their most directly comparable GAAP measures have been provided in the financial statement tables included in this press release, and investors are encouraged to review the reconciliation.
