SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Principles of Consolidation

The condensed consolidated financial statements, which include the accounts of Roku and its wholly-owned subsidiaries, have been prepared in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 13, 2026 (the “Annual Report”).

The condensed consolidated balance sheet as of December 31, 2025 has been derived from the audited consolidated financial statements as of that date but does not include all of the information and footnotes included in the Company’s Annual Report. The interim financial information is unaudited, but reflects all normal recurring adjustments that are, in the opinion of management, necessary to fairly present the information set forth herein. The results of operations for the three months ended March 31, 2026 are not necessarily indicative of the operating results to be expected for the full year or any future periods.

All intercompany accounts and transactions have been eliminated in consolidation. Certain prior period amounts reported in the condensed consolidated financial statements and accompanying notes have been reclassified to conform to the current period presentation.

There have been no material changes to the accounting policies disclosed in the audited consolidated financial statements and the related notes for the year ended December 31, 2025.

Use of Estimates

The preparation of the Company’s condensed consolidated financial statements in accordance with U.S. GAAP requires management to make certain estimates, judgments, and assumptions that affect the reported amounts of assets, liabilities, net revenue, and expenses. Significant items subject to such estimates and assumptions include:

•revenue recognition: determining the nature and timing of satisfaction of performance obligations, variable consideration, determining the stand-alone selling prices of performance obligations, and evaluation of customer versus vendor relationships;

•the impairment of long-lived assets;

•inventory reserves;

•valuation of consideration transferred, assets acquired, and liabilities assumed in connection with business combinations (see Note 4);

•valuation of strategic investments (see Note 9);

•useful lives of tangible and intangible assets;

•allowances for sales returns and sales incentives; and

•the valuation of deferred income tax assets.

The Company bases its estimates on historical experience and on various other assumptions that the Company believes to be reasonable under the circumstances. Actual results may differ from the Company’s estimates and assumptions.

Inventories

The Company’s inventories consist primarily of finished goods and are stated at the lower of cost or net realizable value with cost determined on a first-in, first-out basis. Provisions are made if the cost of the inventories exceeds their net realizable value. The Company evaluates inventory levels for excess and obsolete products, based on its assessment of future demand and market conditions. The Company recognized inventory provisions charged to the Cost of revenue, devices, of $20.7 million and $6.8 million for the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026 and December 31, 2025, the ending inventory reserve was $28.2 million and $29.3 million, respectively.

Recently Adopted Accounting Pronouncements

In July 2025, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU") 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”), which introduces a practical expedient for the application of the current expected credit loss model to current accounts receivable and contract assets. The Company adopted this guidance prospectively effective January 1, 2026 and elected the practical expedient provided by ASU 2025-05. In accordance with this practical expedient, for current accounts receivable and contract assets, the Company assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset. The adoption did not have a material impact on the Company’s consolidated financial statements.

Recent Accounting Pronouncements

In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which simplifies the capitalization guidance by removing all references to software development project stages so that the guidance is neutral to different software development methods. The guidance is effective for fiscal years beginning after December 15, 2027 and interim periods within those fiscal years on a retrospective, modified, or prospective basis. The Company is currently in the process of evaluating the effects of the new guidance.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) - Disaggregation of Income Statement Expenses, which requires additional disclosures of specific expense categories in the notes to the financial statements on an annual and interim basis. The guidance is effective for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027 on a retrospective or prospective basis. The Company is currently in the process of evaluating the effects of the new guidance.
