Hg buys OneStream (NASDAQ: OS) in $6.4B, $24-per-share take-private
Rhea-AI Filing Summary
OneStream, Inc. has completed its acquisition by Hg and is going private in an all-cash deal valuing the company at approximately $6.4 billion. OneStream shareholders are entitled to receive $24.00 per share in cash under the merger agreement.
On the closing date, OneStream became a subsidiary of Onward AcquireCo, Inc., affiliates of Hg, funded by equity from Hg, Tidemark, General Atlantic and other existing stockholders, plus new debt financing. A new senior secured term loan facility of $1.4 billion, a $250 million revolving facility and a $600 million delayed draw term loan were put in place, and prior credit facilities were repaid.
As a result of the transaction, OneStream’s Class A common stock has ceased trading on Nasdaq, and the company is pursuing delisting and deregistration, which will end its public reporting obligations. OneStream will remain led by CEO Tom Shea and its existing leadership team as a privately held company focused on its Finance AI and enterprise finance platform strategy.

Insights
OneStream is taken private in a $6.4 billion, $24/share cash buyout backed by sizable new debt facilities.
The transaction transfers control of OneStream to Hg affiliates via a merger structure, with OneStream and its subsidiary LLC surviving as wholly owned units. Equity funding from Hg, Tidemark, General Atlantic and other existing stockholders is combined with new senior secured credit facilities, including a $1.4 billion term loan, a $250 million revolver and a $600 million delayed draw term loan.
All prior amounts outstanding under OneStream’s existing credit agreement were prepaid and commitments terminated at closing, simplifying debt arrangements under the new structure. Public shareholders receive $24.00 per share in cash and lose further participation, while OneStream’s Class A stock is being delisted and deregistered, ending Exchange Act reporting. The company’s leadership, including CEO Tom Shea, remains in place as it pursues its Finance AI growth strategy under private ownership.

BIRMINGHAM, Mich., April 1, 2026 /PRNewswire/ – OneStream, the leading enterprise Finance management platform that modernizes the Office of the CFO by unifying core Finance and operational functions – including financial close, consolidation, reporting, planning and forecasting – today announced the successful completion of its acquisition by Hg, a leading investor in European and transatlantic technology and services businesses. Minority investors include General Atlantic, a leading global investor, and Tidemark, a leading technology investment firm.
The all-cash transaction values OneStream at approximately $6.4 billion in equity value. With the completion of the transaction, OneStream’s Class A common stock has ceased trading on the NASDAQ.
Backed by investors with deep expertise in scaling category-leading platforms for the Office of the CFO, OneStream is now privately held, with Tom Shea continuing to serve as CEO and the current OneStream leadership team remaining in place.
“Following an exceptional year of growth, including more than doubling our AI customers year over year in 2025, today’s news marks an exciting next step for OneStream,” said Tom Shea, founder and CEO of OneStream. “We believe the leaders in Finance AI will be defined over the next 24 to 36 months, and we are making deliberate, long-term decisions to lead at this critical inflection point. Our strategy, leadership, and commitment to customers and partners remains at the center of this. With Hg’s partnership, we are well positioned to accelerate innovation, scale globally, and deliver even greater value to Finance leaders around the world.”
“We see a tremendous opportunity with OneStream and their vision to be the operating system for Modern Finance,” said Joe Jefferies, Partner at Hg. “There is a fundamental shift in how companies must deliver value in the age of AI. OneStream’s powerful Finance AI differentiation brings AI and Agentic AI solutions to a company’s contextualized business logic, making it a key player in the Finance AI sector. This, coupled with an already strong global customer base and clear vision, makes OneStream a critical addition to our Hg team and we look forward to helping them accelerate innovation and growth.”
