Description of Business and Summary of Significant Accounting Policies | Description of Business and Summary of Significant Accounting Policies Description of Business Pinterest was incorporated in Delaware in 2008 and is headquartered in San Francisco, California. Pinterest is a visual search and discovery platform positioned at the intersection of search, social and commerce. We generate revenue by delivering ads on our website and mobile application. Basis of Presentation and Consolidation We prepared the accompanying condensed consolidated financial statements in accordance with generally accepted accounting principles in the United States ("GAAP"). The condensed consolidated financial statements include the accounts of Pinterest, Inc. and its wholly owned subsidiaries. We have eliminated all intercompany balances and transactions. The condensed consolidated balance sheet as of December 31, 2024 included herein was derived from the audited financial statements as of that date. We have condensed or omitted certain information and notes normally included in complete financial statements prepared in accordance with GAAP. As such, these unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements as of and for the year ended December 31, 2024, which are included in our Annual Report on Form 10-K. In our opinion, the accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the results for the interim periods presented, but they are not necessarily indicative of the results of operations to be expected for the year ending December 31, 2025. Reclassifications We have reclassified certain amounts in prior periods to conform with current presentation. Use of Estimates Preparing our condensed consolidated financial statements in conformity with GAAP requires us to make estimates and judgments that affect amounts reported in the condensed consolidated financial statements and accompanying notes. We base these estimates and judgments on historical experience and various other assumptions that we consider reasonable. GAAP requires us to make estimates and assumptions in several areas, including the fair values of financial instruments, assets acquired and liabilities assumed through business combinations, share-based awards, and contingencies, the recognition, measurement and valuation of deferred income taxes, as well as the collectability of our accounts receivable, the useful lives of our intangible assets and property and equipment, the incremental borrowing rate we use to determine our operating lease liabilities, and revenue recognition, among others. Actual results could differ materially from these estimates and judgments. Segments We operate as a single operating segment. Our chief operating decision maker is our Chief Executive Officer, who reviews financial information presented on a consolidated basis, accompanied by disaggregated information about our revenue, for purposes of making operating decisions, assessing financial performance and allocating resources. Net income (loss) is our primary measure of profit or loss, and all costs and expenses categories on our consolidated statements of operations, as well as share-based compensation expense, are significant. Refer to Note 4 for additional information about our share-based compensation expense. Our other segment items include interest income (expense), net, other income (expense), net and benefit from income taxes on our condensed consolidated statements of operations. Significant Accounting Policies There have been no material changes to our significant accounting policies from our Annual Report on Form 10-K for the year ended December 31, 2024, except for an update to our share-based compensation policy as described below. Share-Based Compensation Restricted stock units ("RSUs"), restricted stock awards ("RSAs") and stock options granted under our 2019 Omnibus Incentive Plan (the "2019 Plan") are generally subject only to a service condition. We also grant awards subject to performance or market conditions to certain executives from time to time. We record share-based compensation expense over the requisite service period of two to four years on a straight-line basis for awards subject only to a service condition and on a graded-vesting basis for awards subject to performance or market conditions. We account for forfeitures as they occur. We measure RSUs and RSAs based on the fair market value of our common stock on the grant date, stock options based on their estimated grant date fair values, which we determine using the Black-Scholes option-pricing model, and awards with a market condition using a Monte Carlo simulation valuation model. Recent Accounting Pronouncements Not Yet Adopted In September 2025, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40), which amends certain aspects of the accounting for and disclosure of software costs. ASU 2025-06 will be effective for us beginning January 1, 2028. The amendments may be applied using a prospective, retrospective, or modified transition approach, and early adoption is permitted. We are currently evaluating the effects of adoption on our condensed consolidated financial statements.
