Why BTIG Downgraded OneStream (OS) After Its $24-Per-Share Buyout Agreement

OneStream, Inc. (NASDAQ:OS) is one of the best rising AI stocks to buy now. On March 6, 2026, BTIG downgraded OneStream to Neutral from Buy without a price target after the company agreed to be acquired (by PE firm Hg Capital) for $24 per share, with the transaction expected to close in the first half of 2026. The analyst said the pending takeover was the reason for the downgrade, not a change in the company’s underlying operating performance.

For context, OneStream reported fourth-quarter 2025 revenue of $163.7 million, up 24% year over year, while subscription revenue rose 27% to $150.3 million. GAAP operating loss narrowed to $5.2 million from $47.4 million a year earlier, while non-GAAP operating income increased to $16.7 million from $8.7 million. Non-GAAP EPS improved to $0.12 from $0.07. For full-year 2025, revenue increased 23% to $601.9 million, and subscription revenue rose 28% to $550.0 million. CEO Tom Shea said 2025 showed strong momentum in Finance AI, with AI bookings and customers more than doubling during the year, while the company also expanded its strategic partnership with Microsoft. Because of the pending Hg acquisition, OneStream said it would not host a quarterly conference call or provide forward-looking guidance.

OneStream, Inc. (NASDAQ:OS) is an enterprise finance software company that provides a cloud platform for financial close, consolidation, reporting, planning, and forecasting. The company says its platform unifies financial and operational data and embeds AI tools to help modernize the Office of the CFO.
