Note 2 –Basis of Presentation and Summary of Significant Accounting Policies

Fiscal Year

The Company’s fiscal year ends on December 31, and its fiscal quarters end on March 31, June 30, September 30, and December 31. References to fiscal year 2026, for example, refer to the fiscal year ending December 31, 2026.

Unaudited Interim Condensed Consolidated Financial Information

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”).

Basis of Presentation

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.

Use of Estimates

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.

Equity Investments

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.

Concentration of Revenue and Accounts Receivable

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 and Allowance for Credit Losses

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.

The following table presents the changes in the allowance for credit losses (in thousands):

Recently Adopted Accounting Pronouncements

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.

Recent Accounting Pronouncements Not Yet Adopted

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.

Note 3 –Fair Value Measurements

The following tables set forth the fair value of the Company’s financial assets and liabilities measured on a recurring basis by level within the fair value hierarchy (in thousands):

The Company’s financial assets consist of Level 1, Level 2, and Level 3 assets. The Company classifies its cash equivalents within Level 1 or Level 2 because they are valued using either quoted market prices or inputs other than quoted prices which are directly or indirectly observable in the market, including readily-available pricing sources for the identical underlying security which may not be actively traded. Certain other assets are classified within Level 3 because factors used to develop the estimated fair value are unobservable inputs that are not supported by market activity.

Note 4 –Balance Sheet Components

Marketable Securities

The following tables summarize the Company’s marketable securities by significant investment categories (in thousands):

There wereno marketable securities as of December 31, 2025. The remaining contractual maturity of all marketable securities was within one year as of June 30, 2026. Realized gains and losses were not material for the six months ended June 30, 2026 and 2025.

Note 5 –Senior Secured Credit Facilities Agreement

On October 17, 2022, the Company entered into a Senior Secured Credit Facilities Credit Agreement (the “Credit Agreement”) with the several lenders parties thereto (the “Lenders”), and Silicon Valley Bank (“SVB”), as administrative agent, lead arranger, issuing lender, and swingline lender. The Credit Agreement matures on October 17, 2027.

The Credit Agreement provides a revolving credit facility in an aggregate principal amount of $110.0 million (“the Revolving Credit Facility”), including a $25.0 million letter of credit sub-facility and a $25.0 million swingline sub-facility. The Company’s obligations under the Revolving Credit Facility and the letter of credit sub-facility (described in Note 8) with SVB are secured by substantially all of its assets excluding its intellectual property. The Company may, subject to certain customary conditions, on one or more occasions increase commitments under the Revolving Credit Facility in an amount not to exceed $90.0 million in the aggregate (the “Incremental Facility”). Each Lender will have discretion to determine whether it will participate in any Incremental Facility.

Borrowings under the Revolving Credit Facility will accrue interest at rates equal, at the Company’s election, to (i) the applicable secured overnight financing rate (“SOFR”), plus the applicable margin for such loans, or (ii) the alternate base rate (“ABR”), which is defined as the highest of (a) the prime rate in effect from time to time, (b) the federal funds effective rate in effect from time to time plus 0.50%, and (c) the adjusted term SOFR for a one (1) month tenor in effect from time to time plus 1.00%, plus the applicable margin for such loans. The applicable margin for borrowings bearing interest on the SOFR ranges from 2.00% to 2.75%, and the applicable margin for borrowings bearing interest based on the ABR ranges from 1.00% to 1.75%. As of June 30, 2026, the applicable interest rate under the revolving credit facility was 7.75%. The Company will pay a quarterly commitment fee during the term of the Credit Agreement for the non-use of available funds ranging from 0.25% to 0.35%. In addition, the Credit Agreement provides a mechanism to determine a successor reference rate to the applicable reference rate if, among other things, the applicable reference rate becomes unavailable or is generally replaced as a benchmark interest rate.

The Credit Agreement contains customary representations and warranties as well as customary affirmative and negative covenants. Negative covenants include, among others, limitations on incurrence of indebtedness, liens, disposition of property and investments by the Company and its subsidiaries. In addition, the Credit Agreement requires the Company to maintain certain interest coverage, leverage and senior leverage ratios. To date, the Company is in compliance with the affirmative and negative covenants.

The Credit Agreement contains customary events of default. Upon the occurrence and during the continuance of an event of default, the Lenders may declare the outstanding advances and all other obligations under the Credit Agreement immediately due and payable.

The Company may use amounts borrowed under the Credit Agreement for general corporate purposes or working capital financing. The Company may borrow additional amounts under the Credit Agreement from time to time as opportunities and needs arise. As of June 30, 2026, the Company has not drawn down on the credit facility.

Following the SVB closure by the California Department of Financial Protection and Innovation on March 10, 2023, and its subsequent receivership by the Federal Deposit Insurance Corporation (“FDIC”), the FDIC announced that all of SVB’s deposits and substantially all of its assets had been transferred to a newly created, full-service FDIC-operated bridge bank, Silicon Valley Bridge Bank, N.A. (“SVBB”). On March 27, 2023, First Citizens Bank & Trust Company (“First Citizens”) acquired substantially all of the loans and certain other assets of the former SVB, and assumed all customer deposits and certain other liabilities of the former SVB. As such, First Citizens assumed SVB’s obligations under the Credit Agreement.

Note 6 –Leases

Operating lease cost is recognized on a straight-line basis over the lease term. Finance lease cost is recognized as a combination of the amortization expense for the right-of-use assets and interest expense for the outstanding lease liabilities, and results in a front-loaded expense pattern over the lease term. Short-term and variable lease costs are not material to the Company’s condensed consolidated financial statements.

The components of lease cost were as follows (in thousands):

As of June 30, 2026, a weighted average discount rate of 5.43% and 2.24% has been applied to the remaining operating and finance lease payments, respectively, to calculate the lease liabilities included within the condensed consolidated balance sheets. The weighted average remaining lease term of operating and finance leases is 7.3 and 1.8 years, respectively, as of June 30, 2026.

As of June 30, 2026, the maturities of lease liabilities under operating and finance leases were as follows (in thousands):

Note 7 –Acquisition-related Intangible Assets, Net

Acquisition-related Intangible Assets, Net

Acquisition-related intangible assets, net consisted of the following (in thousands):

The weighted average remaining useful life of developed technology was 1.25 years as of June 30, 2026. Amortization expense related to acquisition-related intangibles was $0.4 million for each of the three months ended June 30, 2026 and 2025, and $0.8 million for each of the six months ended June 30, 2026 and 2025.

As of June 30, 2026, estimated future amortization expense for acquisition-related intangible assets was as follows (in thousands):

Note 8 –Commitments and Contingencies

Purchase Obligations

The Company’s purchase obligations primarily relate to minimum contractual payments due to data center providers. During the six months ended June 30, 2026, there were no material changes to the Company’s non-cancelable purchase obligations disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

Letters of Credit

As of June 30, 2026 and December 31, 2025, the Company hadthree irrevocable letters of credit outstanding related to non-cancelable facilities leases in the amounts of $3.5 million, $1.5 million, and $0.2 million, with annual automatic renewal and final expiration dates in July 2028, April 2036, and September 2031, respectively.

Legal Matters

From time to time, the Company is or may be involved in various claims and other legal matters arising in the normal course of business. The Company records an accrual for a liability relating to claims and other legal matters when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Any such accruals are reviewed at least quarterly and adjusted for the impacts of negotiations, rulings, settlements, and other information or events pertaining to a particular matter, or on the advice of legal counsel. To date, the Company has not incurred a material loss, or a material loss in excess of a recorded accrual, with respect to any claims and other legal matters arising in the normal course of business. However, the outcomes of claims and other legal matters are inherently unpredictable and subject to significant uncertainties. If the Company subsequently concludes that there is a reasonable possibility that a loss exceeding amounts already recognized may be incurred, and the amount of such additional loss would be material, the Company will either disclose the estimated additional loss or state that such an estimate cannot be made.

Indemnification

In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for general indemnification. The Company’s exposure under these agreements is unknown because it involves future claims that may be made against the Company, but have not yet been made. To date, the Company has not paid any material claims or been required to defend any actions related to its indemnification obligations. However, the Company may record charges in the future as a result of these indemnification obligations. In addition, the Company has indemnification agreements with certain of its directors and executive officers that require it, among other things, to indemnify them against certain liabilities that may arise due to their status or service as directors or officers of the Company. The terms of such obligations may vary.

Executive Transition

In May 2026, the Company entered into a Transition and Amending Agreement with Paulina Klimenko, its then Chief Growth Officer, providing for her continued employment through a July 17, 2026 separation date. The agreement provides a bonus opportunity, prorated for 2026 performance, contingent on continued service through separation and execution of a general release, in lieu of severance under her prior retention agreement. No amounts were accrued under the agreement as of June 30, 2026.

Note 9 –Stockholders’ Equity and Equity Incentive Plans

Share Repurchases

In February 2023, the Company’s board of directors authorized the Company to repurchase up to $75 million of its Class A common stock (as amended, the “2023 Repurchase Program”). In February 2024, the Company’s board of directors authorized the Company to repurchase up to an additional $100 million of its Class A common stock under the 2023 Repurchase Program (the “2024 Repurchase Program Extension”) in addition to the $75 million previously authorized under the 2023 Repurchase Program, and extended the expiration of the 2023 Repurchase Program to December 31, 2025. In May 2025, the Company’s board of directors authorized the Company to repurchase up to an additional $100 million of its Class A common stock under the 2023 Repurchase Program (the “2025 Repurchase Program Extension”) in addition to the aggregate $175 million previously authorized under the 2023 Repurchase Program, and extended the expiration of the 2023 Repurchase Program to December 31, 2026. As of June 30, 2026, $63.6 million remains available for repurchases. Shares are repurchased in a manner deemed in the best interest of the Company and its stockholders, dependent upon business, economic and market conditions, corporate and regulatory requirements, prevailing stock prices and other considerations.

During the six months ended June 30, 2026, the Company repurchased 3,118,823 aggregate shares of Class A common stock for $30.3 million.

Repurchases are executed from time to time, subject to general business and market conditions and other investment opportunities, through open market purchases or privately negotiated transactions, in accordance with Rule 10b-18 and/or Rule 10b5-1 of the Exchange Act. The 2023 Repurchase Program, as amended, is scheduled to terminate on December 31, 2026.

Equity Incentive Plans

The Company maintains the 2020 Equity Incentive Plan (“2020 Plan”), pursuant to which the Company may grant stock options, restricted stock awards, stock appreciation rights, restricted stock units (“RSUs”), deferred stock units (“DSUs”), performance awards, and stock bonus awards. As of June 30, 2026, the Company has reserved 4,713,401 shares of Class A common stock for the issuance of awards under the 2020 Plan. These available shares will increase automatically on January 1 for each of the firstten calendar years during the term of the 2020 Plan by the number of shares equal to the lesser of five percent (5%) of the aggregate number of outstanding shares of all classes of the Company’s common stock outstanding as of the immediately preceding December 31, or a number as may be determined by the Company’s board of directors or compensation committee. No new awards were issued under the Company’s prior 2006 Plan or 2017 Plan (“Prior Plans”) after the effective date of the 2020 Plan. To the extent outstanding awards under the 2006 Plan and the 2017 Plan are forfeited, expire unexercised, or would otherwise have been returned to the share reserve under the Prior Plans, the shares of Class B common stock subject to such awards instead will be available for future issuance as Class A common stock under the 2020 Plan.

Stock Options

The following table summarizes stock option activity and related information under the Company’s equity incentive plans:

As of June 30, 2026, unrecognized stock-based compensation of $11.3 million related to unvested stock options will be recognized on a straight-line basis over a weighted average period of 1.95 years.

Restricted Stock Units

The following table summarizes RSU activity and related information under the Company’s 2020 Plan:

As of June 30, 2026, unrecognized stock-based compensation of $51.2 million related to unvested RSUs will be recognized on a straight-line basis over a weighted average period of 2.57 years.

2020 Employee Stock Purchase Plan

In November 2020, the Company’s board of directors adopted, and its stockholders approved, the 2020 Employee Stock Purchase Plan (“ESPP”), which became effective in connection with the Company’s initial public offering. A total of 500,000 shares of the Company’s Class A common stock were initially reserved for issuance under the ESPP. The aggregate number of shares reserved for issuance under the ESPP will increase automatically on January 1st of each of the firstten calendar years during the term of the ESPP by the number of shares equal to the lesser of (a) 1% of the total outstanding shares of all classes of the Company’s common stock as of the immediately preceding December 31 and (b) such number of shares of common stock as determined by the Company’s board of directors. The aggregate number of shares issued over the term of the ESPP may not exceed 7,500,000 shares of Class A common stock. As of June 30, 2026, the Company has reserved 2,352,578 shares of its common stock for issuance under the ESPP.

As of June 30, 2026, $0.2 million has been withheld on behalf of employees for a future purchase under the ESPP due to the timing of payroll deductions and is included in accrued liabilities. For the six months ended June 30, 2026 and 2025,137,316 and 136,438 shares of our Class A common stock were purchased under the ESPP, respectively.

As of June 30, 2026, unrecognized stock-based compensation expense related to the ESPP was $0.8 million, which is expected to be recognized over a weighted-average period of 0.87 years.

Stock-Based Compensation

Total stock-based compensation expense recognized in the condensed consolidated statements of operations was as follows (in thousands):

Note 10 –Net Loss Per Share

The Company has two classes of common stock, Class A and Class B. Basic and diluted earnings per share (“EPS”) attributable to common stockholders for Class A and Class B common stock were the same because they were entitled to the same liquidation and dividend rights.

The following table sets forth the computation of the Company’s basic and diluted net loss per share (in thousands, except per share data):

The following weighted-average outstanding shares of common stock equivalents were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented because including them would have been anti-dilutive (in thousands):

Note 11 –Income Taxes

The Company has historically calculated the provision for income taxes during interim reporting periods by applying an estimate of the annual effective tax rate (“AETR”) for the full fiscal year to “ordinary” income or loss (pretax income or loss excluding unusual or infrequently occurring discrete items) for the reporting period. The Company has determined the historical method would not provide a reliable estimate for the fiscal six months ended June 30, 2026. Therefore, the discrete effective tax rate method has been used to calculate taxes for the fiscal six months ended June 30, 2026.

The Company recorded a provision for income taxes of $3.1 million and a benefit from income taxes of $0.9 million for the three months ended June 30, 2026 and 2025, respectively, and a provision for income taxes of $0.5 million and a benefit from income taxes of $2.7 million for the six months ended June 30, 2026 and 2025, respectively.

The effective income tax rate was 164% and 14% for the three months ended June 30, 2026 and 2025, respectively, and (4)% and 16% for the six months ended June 30, 2026 and 2025, respectively. The provision for income taxes for the six months ended June 30, 2026 is primarily related to tax expense from nondeductible stock-based compensation and Section 162(m) limitation on the tax deductibility of officers’ compensation, partially offset by the tax benefits from research tax credits and deductions for equity awards.

Realization of the Company’s deferred tax assets is dependent primarily on the generation of future taxable income. In considering the need for a valuation allowance, the Company considers its historical, as well as future projected, taxable income along with other objectively verifiable evidence. Objectively verifiable evidence includes the Company’s realization of tax attributes, assessment of tax credits, and utilization of net operating loss carryforwards during the year.

Note 12 –Segment and Geographical Information

Segment Information

Operating segments are components of an enterprise for which separate financial information is available and evaluated regularly by the Company’s chief operating decision maker in deciding how to allocate resources and assessing performance. The Company’s chief operating decision maker (“CODM”) is its Chief Executive Officer.

The primary measure of segment profit or loss is consolidated net income (loss) as presented below and is used by the CODM for purposes of allocating resources and evaluating financial performance. The Company has one business activity and there are no segment managers accountable for operations, operating results beyond revenue or gross profit, or plans for levels or components below the consolidated unit level. Accordingly, the Company hasone single reporting segment.

The following table presents selected financial information with respect to the Company’s single operating segment for the three and six months ended June 30, 2026 and 2025 (in thousands):

(1)Employee compensation includes employee payroll, share-based compensation, bonus, and employee benefits for medical care, retirement, insurances, and other related expenses.

(2)Other segment items includes costs and expenses from operation of the Company’s data centers, professional services, facilities, marketing, and other related expenses.

Geographical Information

The following table presents total revenue by geographic area based on the publisher’s billing address (in thousands):

No other country besides the United States represented more than ten percent of total revenue during the three and six months ended June 30, 2026 and 2025.

The following table presents long-lived assets, net, which consist primarily of property and equipment and operating lease right-of-use assets, by geographic area (in thousands):

Note 13 –401(k) Plan

The Company has a 401(k) Savings Plan (the “401(k) Plan”) that qualifies as a deferred salary arrangement under Section 401(k) of the Internal Revenue Code. Under the 401(k) Plan, participating employees may elect to contribute up to 100% of their eligible compensation, subject to certain limitations. The 401(k) Plan provides for a discretionary employer matching contribution. The Company made $0.9 million in matching contributions to the 401(k) Plan for each of the six months ended June 30, 2026 and 2025.

Note 14 –Subsequent Event

On August 6, 2026, the Company announced the future planned retirement of Steven Pantelick, its Chief Financial Officer. Additional information regarding this transition is set forth in the Company's Current Report on Form 8-K filed with the Securities and Exchange Commission on August 6, 2026.
