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.
