Welcome to our dedicated page for ONESTREAM SEC filings (Ticker: OS), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
The OneStream, Inc. (OS) SEC filings page on Stock Titan aggregates the company’s regulatory disclosures from the U.S. Securities and Exchange Commission, giving investors structured access to its official communications. As a Nasdaq-listed software company focused on enterprise Finance management and AI-enabled solutions, OneStream uses SEC filings to report financial results, corporate governance changes and other material events.
Among the key documents available are Form 8-K current reports, which OneStream files to announce items such as quarterly financial results and board or leadership changes. For example, the company has filed 8-Ks in connection with its second and third quarter 2025 results and to report the appointment of a new director to its Board. These filings often reference accompanying earnings press releases that detail revenue composition, non-GAAP metrics like non-GAAP operating income and non-GAAP net income per share, and definitions of measures such as free cash flow.
Investors can also use the filings page to track how OneStream defines and reconciles non-GAAP metrics used in its communications. The company explains in its materials that non-GAAP measures are intended to supplement GAAP results by excluding certain non-cash, non-operational or non-recurring items, and provides reconciliations in tables attached to its earnings releases.
As OneStream has announced a definitive agreement to be acquired by an entity controlled by Hg, future SEC filings are expected to include documents related to that transaction, subject to regulatory requirements. On Stock Titan, these filings are accompanied by AI-powered summaries that highlight key points, helping readers quickly understand the nature of each report—whether it concerns results of operations, board changes, or transaction-related disclosures—while still allowing access to the full original documents and exhibits.
OneStream, Inc. CEO and director Thomas Anthony Shea reported a Form 4 showing that 9,258 shares of Class A Common Stock were withheld at $23.70 per share to satisfy tax obligations on restricted stock unit settlement, which the company notes is not a market sale. After this tax-withholding disposition, he directly holds 459,986 shares, including unvested restricted stock units.
OS reports a Form 144 notice for the proposed disposition of 7,412 shares of Class A common stock tied to a restricted stock vesting event. The filing lists the proposed sale method as Issuer placement on 03/10/2026. The filing also records prior dispositions of 6,011 Class A shares on 12/11/2025.
OneStream, Inc. files its annual report, highlighting a pending agreement to be acquired by affiliates of Hg. At closing, each share of Class A and Class D common stock and each LLC Unit will be converted into $24.00 in cash, while Class B and Class C shares will receive $0.0001 in cash, subject to the Merger Agreement terms.
The mergers are expected to close in the first half of 2026, contingent on regulatory clearances, including under the HSR Act, and other customary conditions. OneStream describes its unified, AI‑enabled Digital Finance Cloud platform for the Office of the CFO, its Solution Exchange ecosystem and a partner network that includes major global consultancies.
The company reports rapid customer growth to 1,805 customers and expanding international revenue, but also details risks: potential failure or delay of the mergers, related litigation, strong competition from large software vendors, continued operating losses, a complex tax receivable agreement structure and concentrated voting control through high‑vote Class C and D shares, including holdings by KKR.
OneStream, Inc. reported strong fourth quarter and full-year 2025 results, showing fast growth and improving profitability while preparing to go private in a pending sale to Hg. For Q4 2025, total revenue reached $163.7 million, up 24%, with subscription revenue of $150.3 million, up 27% year over year.
GAAP operating loss narrowed sharply to $5.2 million with a (3%) margin, compared with a (36%) margin a year earlier, helped by lower equity-based compensation. Non-GAAP operating income rose to $16.7 million with a 10% margin, and GAAP net income per share turned positive at $0.01, while non-GAAP net income per share increased to $0.12.
For 2025, revenue grew 23% to $601.9 million, subscription revenue rose 28% to $550.0 million, and non-GAAP operating income increased to $27.1 million with a 5% margin. Free cash flow improved to $95.6 million. The company highlighted rapid adoption of its Finance AI offerings and an expanded strategic alliance with Microsoft. Due to the pending Hg acquisition, it will not host an earnings call or provide guidance.
OneStream, Inc. Chief Revenue Officer Ken Hohenstein reported option exercises and share sales. On February 17, 2026, he exercised stock options covering 60,000 shares of Class A common stock at exercise prices of $10.65 and $14.51 per share, and then sold 60,000 shares of Class A common stock at $23.46 per share in an open-market transaction effected under a Rule 10b5-1 trading plan adopted on August 22, 2025. Following these transactions, he directly held 990,961 shares of Class A common stock and also had indirect ownership of 790,279 shares, which includes shares held by the Hohenstein Purple Elephant 2019 Irrevocable Grantor Trust and unvested restricted stock units.
A shareholder filed a notice to sell 60,000 Class A shares of OS, to be handled by Fidelity Brokerage Services LLC on or about 02/17/2026. The aggregate market value of this planned sale is listed as $1,407,600.00, and the shares trade on NASDAQ, with 90,268,494 Class A shares outstanding.
The shares to be sold were acquired by exercising stock options granted in 2022, 2023, and 2024, with exercises on 02/17/2026 for cash totaling 60,000 shares. In the prior three months, an individual named Kenneth D. Hohenstein sold 40,000 and 120,000 Class A shares on 11/17/2025 and 01/16/2026, for gross proceeds of $837,773.00 and $2,835,636.00, respectively.
T. Rowe Price Investment Management, Inc. filed an amended Schedule 13G reporting beneficial ownership of 7,779,413 shares of INC common stock, representing 8.6% of the class as of December 31, 2025. It reports sole power to vote 7,764,467 shares and sole power to dispose of 7,779,413 shares, with no shared voting or dispositive power. The firm states the shares were acquired and are held in the ordinary course of business and not to change or influence control of the company, and it expressly denies being the beneficial owner of the securities referenced.
OneStream, Inc. has agreed to be acquired and taken private by Onward AcquireCo Inc., an affiliate of private‑equity firm Hg, through a two‑step merger structure. Merger subsidiaries will combine with OneStream and its operating LLC, leaving both as wholly owned subsidiaries of Parent.
The OneStream board unanimously approved the Merger Agreement, determined it is fair and in the best interests of stockholders, and obtained fairness opinions from J.P. Morgan and Centerview Partners on the cash consideration for Class A common stock. Hg’s funds have committed equity financing, with an aggregate equity commitment cap of approximately $5.6 billion to cover merger consideration and related costs.
KKR‑affiliated holders controlling about 58 percent of the voting power have already delivered a written consent adopting the Merger Agreement, so no further stockholder vote or proxies are being solicited. Non‑consenting stockholders are instead given an information statement and notice of appraisal rights under Delaware law.
If the mergers close, OneStream’s Class A shares will be delisted from Nasdaq, deregistered under the Exchange Act and converted into cash, and the company will cease to be publicly traded. An example in the document notes that 100 shares of Class A common stock would receive $2,400 in cash, before any taxes or withholding. A tax receivable agreement will be amended so that it terminates at closing without change‑of‑control payments, and a no‑shop and no board‑recommendation‑change covenant applies after the majority written consent. The deal is subject to customary conditions, including antitrust and foreign investment clearances, and includes a termination fee framework and specific‑performance remedies.
Thomas Anthony Shea filed an amended Schedule 13G reporting significant ownership in OneStream, Inc. Class A common stock. He beneficially owns 18,173,259 shares on an as-converted basis, representing 16.3% of the class.
Shea has sole voting and dispositive power over 5,897,454 shares and shared voting and dispositive power over 12,275,805 shares held through family trusts and related entities. The stake includes Class D common stock that is convertible into Class A common stock, as well as options exercisable within 60 days of December 31, 2025.
