OneStream announced it has agreed to be acquired by software investor Hg in an all-cash transaction that values the company at approximately $6.4 billion in equity. Under the agreement, Hg will become the majority voting shareholder, while General Atlantic and Tidemark will hold significant minority stakes. Shareholders will receive $24.00 per share, representing a 31% premium to the company’s closing price on January 5, 2026. The deal, unanimously approved by OneStream’s board, is expected to close in the first half of 2026, subject to regulatory approvals. Following completion, OneStream will operate as a privately held company, and its shares will no longer trade publicly. Chief Executive Officer Tom Shea will continue to lead the company from its headquarters in Birmingham, Michigan.
Shea described the transaction as a strategic step for the company’s future. “Today marks a pivotal moment for OneStream and our vision to be the operating system for modern Finance,” he stated, adding that the partnership will support faster execution and expanded AI capabilities for finance teams. Hg Partner Alan Cline highlighted, “OneStream’s AI differentiation, strong customer base, and clear vision make it exceptionally well positioned for the future.” Hg indicated it will provide operational support and dedicated AI resources to OneStream, while General Atlantic emphasized the platform’s value in helping finance teams address increasing complexity and planning requirements.
