Financial Outlook

For the fourth quarter of 2026, we expect:

•Revenue of $3.9 - $4.0 billion;

•Non-GAAP operating margin of 48 - 49%; and

•Non-GAAP diluted net income per share of $1.26 - $1.30.

Guidance for non-GAAP financial measures excludes certain items, including stock-based compensation expense, intangible asset amortization, tax benefits on stock-based awards, the income tax effect on non-GAAP exclusions, 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 and tax benefits on stock-based awards, which are impacted by the timing of employee stock transactions, 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, operating margin and diluted net income per share.
