Wilson Sonsini Advises OneStream on Acquisition by Hg

Client Highlights

January 7, 2026

On January 6, 2026, OneStream, the leading enterprise finance management platform, announced that it has entered into a definitive agreement to be acquired by Hg, a leading investor in software, services, and data businesses. The all-cash transaction values OneStream at approximately $6.4 billion in equity value. Wilson Sonsini Goodrich & Rosati advised OneStream on this transaction in a continuation of its long-standing advisory relationship with the company, including leading OneStream’s Up-C IPO in July 2024.

Under the terms of the agreement, OneStream shareholders will receive $24.00 per share in cash. The per-share purchase price represents a 31 percent premium to OneStream’s closing share price on January 5, 2026, and a 27 percent premium to its volume-weighted average share price over the 30-trading day period ending the same date. The transaction 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. KKR, in its capacity as the holder of a majority of OneStream’s voting power, has approved the transaction.
