Senior Secured Credit Facilities Agreement	3 Months Ended
Senior Secured Credit Facilities Agreement	Mar. 31, 2024
Debt Disclosure [Abstract]
Senior Secured Credit Facilities Agreement	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 million (“the Revolving Credit Facility”), including a $25 million letter of credit sub-facility and a $25 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 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 March 31, 2024, the applicable interest rate under the revolving credit facility was 9.50%. 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 March 31, 2024, 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 Citizen assumed SVB’s obligations under the Credit Agreement.

The Company’s financial assets consist of Level 1 and 2 assets. The Company had no Level 3 assets or liabilities for the periods presented. The Company classifies its cash equivalents and marketable securities 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. The Company’s fixed income available-for-sale securities consist of high quality, investment grade securities from diverse issuers. The valuation techniques used to measure the fair value of the Company’s marketable securities were derived from non-binding market consensus prices that are corroborated by observable market data and quoted market prices for similar instruments.

Accounting Policies [Abstract]

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 2024, for example, refer to the fiscal year ending December 31, 2024.

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, 2024 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, 2023, as filed with the SEC on February 28, 2024 (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. Certain prior period amounts reported in our condensed consolidated financial statements and notes thereto have been reclassified to conform to the current period presentation.

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 March 31, 2024, may result in actual outcomes that differ from those contemplated by the Company’s assumptions and estimates.

Concentration of Revenue and Accounts Receivable

The Company defines its revenue concentration based on revenue recognized from individual publishers. For the three months ended March 31, 2024 and 2023, no publisher represented more than 10% and one publisher represented 11% of the Company’s revenue, respectively. As of March 31, 2024, three buyers accounted for 33%, 22%, and 11% respectively, of accounts receivable. As of December 31, 2023, three buyers accounted for 30%, 21%, 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):


	Three Months Ended March 31,
	2024		2023
Allowance for credit losses, beginning balance	$	770	$	1,765
Increase in provision for expected credit losses	—		—
Write-offs	163		—
Allowance for credit losses, ending balance	$	933	$	1,765

Recent Accounting Pronouncements Not Yet Adopted

In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-07 "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures" which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for our annual periods beginning January 1, 2024, and for interim periods beginning January 1, 2025, with early adoption permitted. We are currently evaluating the potential effect that the updated standard will have on our financial statement disclosures.

In December 2023, FASB issued ASU 2023-09 "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" to expand the disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes paid. ASU 2023-09 is effective for our annual periods beginning January 1, 2025, with early adoption permitted. We are currently evaluating the potential effect that the updated standard will have on our financial statement disclosures.

Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2024
Income Tax Disclosure [Abstract]
Income Taxes	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 discrete effective tax rate method has been used to calculate taxes for the fiscal three months ended March 31, 2024. The Company has determined that since small changes in estimated “ordinary” income would result in significant changes in the estimated AETR, the historical method would not provide a reliable estimate for the fiscal three months ended March 31, 2024. The Company recorded a benefit from income taxes of $0.2 million and $3.4 million for the three months ended March 31, 2024 and 2023, respectively. The effective income tax rate was 9% and 37% for the three months ended March 31, 2024 and 2023, respectively. The benefit from income taxes for the three months ended March 31, 2024 is related to tax benefits from foreign-derived intangible income (FDII), research tax credits, and deductions for equity awards, offset by nondeductible stock-based compensation and Section 162(m) limitation on the tax deductibility of officers’ compensation. 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.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Commitments and Contingencies	Mar. 31, 2024
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Purchase Obligations The Company’s purchase obligations primarily relate to minimum contractual payments due to data center providers. During the three months ended March 31, 2024, 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, 2023. Letters of Credit As of March 31, 2024 and December 31, 2023, the Company had two irrevocable letters of credit outstanding related to non-cancelable facilities leases in the amounts of $3.5 million and $0.5 million, with annual automatic renewal and final expiration dates in July 2028 and April 2025, 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

Accounting Policies [Abstract]
Basis of Presentation	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. Certain prior period amounts reported in our condensed consolidated financial statements and notes thereto have been reclassified to conform to the current period presentation.
Use of Estimates	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 March 31, 2024, may result in actual outcomes that differ from those contemplated by the Company’s assumptions and estimates.
Concentration of Revenue and Accounts Receivable	Concentration of Revenue and Accounts Receivable The Company defines its revenue concentration based on revenue recognized from individual publishers
Recently Adopted Accounting Pronouncements	Recent Accounting Pronouncements Not Yet Adopted In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-07 "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures" which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for our annual periods beginning January 1, 2024, and for interim periods beginning January 1, 2025, with early adoption permitted. We are currently evaluating the potential effect that the updated standard will have on our financial statement disclosures. In December 2023, FASB issued ASU 2023-09 "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" to expand the disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes paid. ASU 2023-09 is effective for our annual periods beginning January 1, 2025, with early adoption permitted. We are currently evaluating the potential effect that the updated standard will have on our financial statement disclosures.

Equity [Abstract]

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 (“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 (“2024 Repurchase Program”) in addition to the $75 million previously authorized under the 2023 Repurchase Program. As of March 31, 2024, $100.0 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 three months ended March 31, 2024, the Company repurchased 894,651 aggregate shares of Class A common stock for $15.7 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 is scheduled to terminate on December 31, 2024, while the 2024 Repurchase Program is scheduled to terminate on December 31, 2025.

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 March 31, 2024, the Company has reserved 3,025,245 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 first ten 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.

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”).

The aggregate number of shares reserved for issuance under the ESPP increases automatically on January 1st of each of the first ten 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 March 31, 2024, the Company had reserved 401,599 shares of its Class A common stock for issuance under the ESPP.

Under the ESPP, Class A common stock will be purchased for the accounts of employees participating in the ESPP on each purchase date at a price per share equal to 85% of the lesser of: (a) the fair market value on the offering date or (b) the fair market value on the purchase date. The ESPP provides for, at maximum, 27 month offering periods and each offering period may consist of one or more six-month purchase periods, whereby the latest offering period commenced on June 1, 2022, and the offering periods thereafter consist of two six-month purchase periods ending May 31, 2023. As of March 31, 2024, $1.1 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 three months ended March 31, 2024 and 2023, no shares of our Class A common stock were purchased under the ESPP.

As of March 31, 2024, unrecognized stock-based compensation expense related to the ESPP was $0.2 million, which is expected to be recognized over a weighted-average period of 0.17 years.

Leases

Leases [Abstract]

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.

During the three months ended March 31, 2024, operating right-of-use assets obtained in exchange for new lease obligations was $4.0 million.

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


	Three Months Ended March 31,
	2024		2023
Operating lease cost	$	2,019	$	1,834
Finance lease cost	47		47
Total lease cost	$	2,066	$	1,881

As of March 31, 2024, a weighted average discount rate of 3.15% 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 3.7 and 4.0 years, respectively, as of March 31, 2024.

As of March 31, 2024, the maturities of lease liabilities under operating and finance leases were as follows (in thousands):


	Operating Leases		Finance Leases		Total
