Accounting Policies [Abstract]
Significant Accounting Policies	NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES Significant Accounting Policies There have been no material changes in the Company’s significant accounting policies as of and for the three months ended March 31, 2025, as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 filed with the Securities and Exchange Commission (SEC) on February 27, 2025. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and applicable rules and regulations of the SEC regarding interim financial information. The condensed consolidated financial statements include the results of the Company and its wholly owned subsidiaries. As the Reorganization Transactions are considered transactions between entities under common control, the financial statements for periods prior to the IPO and Reorganization Transactions have been adjusted to combine the previously separate entities for presentation purposes. Prior to the Reorganization Transactions, OneStream, Inc. had no operations. All significant intercompany transactions and balances have been eliminated during consolidation. The unaudited condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all normal recurring adjustments necessary to present fairly the balance sheets, statements of operations, statements of comprehensive loss, statements of stockholders’ / members’ equity and statements of cash flows for the interim periods, but are not necessarily indicative of the results to be expected for the full year or any other future period. Certain information and disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC for interim financial information. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes for the year ended December 31, 2024 included in the Company’s Annual Report on Form 10-K. Use of Estimates The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and the accompanying footnotes. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions that management believes to be reasonable under the circumstances. Actual results could differ from those estimates. Segment Information The Company operates in one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker (CODM), who, in the Company’s case, is the Chief Executive Officer (CEO), in deciding how to allocate resources and assessing performance. The Company’s CODM allocates resources and assesses performance based upon financial information on a consolidated basis, primarily using consolidated net income (loss) as the measure of profit or loss to make key operating decisions. Consolidated expense information, as presented on the condensed consolidated statements of operations, is regularly provided to the CODM. Deferred Offering Costs Deferred offering costs consist primarily of accounting, legal and other fees related to the Company’s IPO. During the year ended December 31, 2024, the Company capitalized $7.2 million of offering costs related to the 2024 IPO, and after completion of the IPO, these costs were reclassified into stockholders’ / members’ equity as a reduction against the proceeds received from the IPO. Concentration of Risk and Significant Customers Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company maintains its cash deposits with high-quality financial institutions with investment-grade ratings. The majority of the Company’s cash balances are with U.S. banks and are insured to the extent defined by the Federal Deposit Insurance Corporation (FDIC) and may, at times, exceed FDIC limits. No customer accounted for more than 10% of total revenue and no customer accounted for more than 10% of total accounts receivable in any period presented. The Company relies upon a limited number of third-party hosted cloud computing vendors to serve customers and operate certain aspects of its services, such as environments for production, and development usage. Given this, any disruption of or interference at the hosted infrastructure partners would impact the Company’s operations and the Company’s business could be adversely impacted. Equity-based Compensation The Company has issued equity-based awards to employees in the form of restricted stock units (RSUs) and stock options, and, prior to the Reorganization Transactions, OneStream Software LLC issued ICUs and common unit options, as described in Note 10. The Company accounts for equity-based awards based on their grant date fair values. Determining the grant date fair values of equity-based awards may require management to make assumptions and judgments. These assumptions reflect the Company’s best estimates, but they involve inherent uncertainties based on market conditions. As a result, if other assumptions are used, equity-based compensation costs could be materially impacted. Equity-based compensation expense is recognized on a straight-line basis for awards with service-only vesting conditions, whereas awards with performance conditions are recognized using the accelerated attribution method. Forfeitures are accounted for as they occur. The Company accounts for the Amended and Restated Employee Stock Purchase Plan (the ESPP) in accordance with Accounting Standards Codification (ASC) 718, Compensation—Stock Compensation, and generally recognizes equity-based compensation expense on a straight-line basis over the term of each offering period. The Black-Scholes option pricing model is used to determine the fair value of the ESPP awards as of the beginning of the offering period. Certain features of the ESPP may require the Company to apply modification accounting as outlined in ASC 718. Refer to Note 10, Equity-based Compensation, for further details on the Company’s equity-based compensation awards. Net Loss per Share Basic net loss per share for the three months ended March 31, 2025 is computed by dividing net loss attributable to OneStream, Inc. by the weighted-average number of shares of Class A common stock and Class D common stock outstanding during the period, excluding dilutive shares. Diluted net loss per share is computed by giving effect to the weighted-average potentially dilutive shares for the applicable period, including additional shares of Class D common stock issuable upon redemption of LLC Units held by Continuing Members, and Class A common stock issuable pursuant to outstanding stock options, RSUs and purchase rights committed under the ESPP, as applicable. The potentially dilutive shares of common stock are computed using the treasury stock method. Diluted net loss per share for all periods presented is the same as basic net loss per share as the inclusion of potentially issuable shares would be anti-dilutive. All losses and earnings for the period prior to the IPO were entirely allocable to OneStream Software LLC. Due to the impact of the Reorganization Transactions, the Company’s capital structure for the pre- and post-IPO periods is not comparable. As a result, the presentation of net (loss) income per share for the periods prior to the IPO and Reorganization Transactions is not meaningful and only net loss per share for periods subsequent to the IPO and Reorganization Transactions are presented herein.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and applicable rules and regulations of the SEC regarding interim financial information. The condensed consolidated financial statements include the results of the Company and its wholly owned subsidiaries. As the Reorganization Transactions are considered transactions between entities under common control, the financial statements for periods prior to the IPO and Reorganization Transactions have been adjusted to combine the previously separate entities for presentation purposes. Prior to the Reorganization Transactions, OneStream, Inc. had no operations. All significant intercompany transactions and balances have been eliminated during consolidation.

The unaudited condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all normal recurring adjustments necessary to present fairly the balance sheets, statements of operations, statements of comprehensive loss, statements of stockholders’ / members’ equity and statements of cash flows for the interim periods, but are not necessarily indicative of the results to be expected for the full year or any other future period. Certain information and disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC for interim financial information.

These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes for the year ended December 31, 2024 included in the Company’s Annual Report on Form 10-K.

Use of Estimates

Management bases its estimates on historical experience and on various other market-specific and relevant assumptions that management believes to be reasonable under the circumstances. Actual results could differ from those estimates.

No customer accounted for more than 10% of total revenue and no customer accounted for more than 10% of total accounts receivable in any period presented.

The Company relies upon a limited number of third-party hosted cloud computing vendors to serve customers and operate certain aspects of its services, such as environments for production, and development usage. Given this, any disruption of or interference at the hosted infrastructure partners would impact the Company’s operations and the Company’s business could be adversely impacted.

Equity-based Compensation

The Company has issued equity-based awards to employees in the form of restricted stock units (RSUs) and stock options, and, prior to the Reorganization Transactions, OneStream Software LLC issued ICUs and common unit options, as described in Note 10. The Company accounts for equity-based awards based on their grant date fair values. Determining the grant date fair values of equity-based awards may require management to make assumptions and judgments.

Certain features of the ESPP may require the Company to apply modification accounting as outlined in ASC 718. Refer to Note 10, Equity-based Compensation, for further details on the Company’s equity-based compensation awards.

Net Loss per Share

Basic net loss per share for the three months ended March 31, 2025 is computed by dividing net loss attributable to OneStream, Inc. by the weighted-average number of shares of Class A common stock and Class D common stock outstanding during the period, excluding dilutive shares. Diluted net loss per share is computed by giving effect to the weighted-average potentially dilutive shares for the applicable period, including additional shares of Class D common stock issuable upon redemption of LLC Units held by Continuing Members, and Class A common stock issuable pursuant to outstanding stock options, RSUs and purchase rights committed under the ESPP, as applicable. The potentially dilutive shares of common stock are computed using the treasury stock method. Diluted net loss per share for all periods presented is the same as basic net loss per share as the inclusion of potentially issuable shares would be anti-dilutive.

All losses and earnings for the period prior to the IPO were entirely allocable to OneStream Software LLC. Due to the impact of the Reorganization Transactions, the Company’s capital structure for the pre- and post-IPO periods is not comparable. As a result, the presentation of net (loss) income per share for the periods prior to the IPO and Reorganization Transactions is not meaningful and only net loss per share for periods subsequent to the IPO and Reorganization Transactions are presented herein.
