The unaudited condensed consolidated financial statements include the accounts of PubMatic, Inc. and its wholly owned subsidiaries, and have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and following the requirements of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP can be condensed or omitted. These financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for the fair statement of the Company’s financial information. These interim results are not necessarily indicative of the results to be expected for the fiscal year ending December 31, 2026 or for any other interim period or for any other future year. The accompanying unaudited condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025, as filed with the SEC on February 26, 2026 (the “Annual Report”).

The accompanying condensed consolidated financial statements have been prepared in accordance with GAAP. The accompanying condensed consolidated financial statements include the accounts of PubMatic, Inc. and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenue and expenses.

The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could materially differ from those estimates and assumptions. Due to the inherent uncertainty involved in making assumptions and estimates, events and changes in circumstances arising after June 30, 2026 may result in actual outcomes that differ from those contemplated by the Company’s assumptions and estimates.

The Company holds strategic investments in privately held, non-marketable equity securities. The Company’s non-marketable equity investments are without a readily determinable fair value and therefore are accounted for using the measurement alternative. Non-marketable equity investments accounted for using the measurement alternative are recorded at cost, less any impairment, and are adjusted for changes in fair value resulting from observable transactions for identical or similar investments of the same issuer as of the respective transaction dates.

The Company periodically reviews its non-marketable equity investments for impairment. When indicators of impairment exist and the estimated fair value of an investment is below its carrying amount, a write down of the investment to its fair value is recorded in other income (expense), net in the condensed consolidated statements of operations.

The Company defines its revenue concentration based on revenue recognized from individual publishers. For the three and six months ended June 30, 2026 and 2025, no publisher represented more than 10% of the Company’s revenue. As of June 30, 2026, three buyers accounted for 29%, 15%, and 15%, respectively, of accounts receivable. As of December 31, 2025, three buyers accounted for 24%, 16%, and 14%, respectively, of accounts receivable.

Accounts receivable are recorded at the invoiced amount, are unsecured, and do not bear interest. The allowance for credit losses is based on the best estimate of the amount of probable credit losses in existing accounts receivable. The allowance for credit losses is determined based on historical collection experience and the review in each period of the status of the then outstanding accounts receivable, while taking into consideration current customer information, collection history, and other relevant data. Account balances are written off against the allowance when the Company believes it is probable the receivable will not be recovered.

In July 2025, the FASB issued ASU 2025-05 “Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses for Accounts Receivable and Contract Assets” (“ASU 2025-05”), which provides a practical expedient to measure credit losses on current accounts receivable. The practical expedient allows companies to assume that current conditions as of the balance sheet date do not change for the remaining life of the asset when measuring credit losses. ASU 2025-05 is effective for annual periods beginning after December 15, 2025 and for interim periods within those annual reporting periods on a prospective basis. The Company adopted ASU 2025-05 on January 1, 2026. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

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”, requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 will be effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact adopting ASU 2024-03 will have on its financial statement disclosures.

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” (“ASU 2025-06”), simplifies the capitalization guidance by removing all references to prescriptive and sequential software development project stages so that the guidance is neutral to different software development methods. ASU 2025-06 will be effective for annual periods beginning after December 15, 2027. The Company is currently evaluating the impact of this accounting standard on its consolidated financial statements and disclosures.

In December 2025, the FASB issued ASU No. 2025-11, “Interim Reporting (Topic 270): Narrow-Scope Improvements” (“ASU 2025-11”), which clarifies interim disclosure requirements and the applicability of Topic 270. The guidance will be effective for interim periods beginning January 1, 2028. Early adoption is permitted. Upon adoption, the guidance can be applied prospectively or retrospectively. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements and disclosures.
