On January 6, 2026, OneStream announced that it had agreed to be acquired by private equity firm Hg at a price of $24.00 per share in cash. Following the closing of the proposed transaction, OneStream shareholders will be cashed out of their investment position and the company’s shares will no longer be publicly traded.

The investigation seeks to determine whether investors will be receiving a sufficiently high cash price for their shares, and whether the company’s representatives breached their fiduciary duties to investors in agreeing to the buyout price. Notably, at the time the proposed transaction was announced, several stock analysts were maintaining a price target for OneStream’s shares of $27.00 per share.
