In an all-cash transaction that takes the US financial software maker private only 17 months after its initial public offering, OneStream is to be acquired by buyout firm Hg for approximately $6.4bn.
Under the terms of the definitive agreement, OneStream shareholders will receive $24 per share in cash. The per-share purchase price represents a 31 percent premium to OneStream’s closing share price on 5 January 2026.
Upon completion of the transaction, OneStream will become a privately held company and will no longer be listed or traded on any public stock exchange.
OneStream’s majority voting shareholder General Atlantic, a leading global investor, will also be a significant minority investor alongside Tidemark, a leading technology investment firm.
“This transaction marks a pivotal moment for OneStream and our vision to be the operating system for modern finance,” said Tom Shea, chief executive of OneStream. “As we build on our strong foundation of growth, we are thrilled to partner with the teams at Hg, General Atlantic and Tidemark. Through this partnership, we are able to significantly advance our artificial intelligence (AI)-first go-to-market strategy and expand our finance AI capabilities at a rapid pace.”
With over 1700 customers, including 18 percent of the Fortune 500, a strong ecosystem of go to market, implementation and development partners and 1600 employees, OneStream’s vision is to be the operating system for modern finance.
“We are excited to support Mr Shea and the OneStream team,” said Joe Jefferies, a partner at Hg. “We will seek to preserve the strong customer focus and entrepreneurial culture that have been central to their success, while bringing Hg’s deep expertise in scaling software businesses. This includes support from our AI team of over 100 specialists and supporting partnerships.”
Following closure, Mr Shea will continue to serve as chief executive of OneStream alongside the current leadership team, with the company maintaining its headquarters in Birmingham, Michigan.
The transaction, which has been unanimously approved by OneStream’s board of directors, is expected to close in the first half of 2026, subject to the receipt of required regulatory approvals and the satisfaction of other customary closing conditions.
“This transaction delivers immediate value to our shareholders and is a vote of confidence in our strategy, our talented employees and our partner ecosystem,” noted Mr Shea. “We look forward to having the ability to move faster, think bigger and deliver more for our forward-thinking finance customers.”
