Simulations Plus announced that it has entered into a definitive agreement to be acquired by affiliates of Altaris in an all-cash transaction valued at approximately $375 million.
Under the agreement, Simulations Plus stockholders will receive $18.50 per share in cash, representing a 26% premium to the company’s 60-day volume-weighted average price as of June 15, 2026.
Altaris expects to combine Simulations Plus with Chemical Computing Group (CCG), an existing portfolio company that provides molecular design software to customers across the pharmaceutical, chemical, and materials sectors.
The transaction was unanimously approved by the Simulations Plus Board of Directors and is expected to close in the fourth quarter of 2026, subject to customary closing conditions, including approval by Simulations Plus stockholders and required regulatory approvals.
The acquisition will be financed through a combination of committed equity and debt financing from funds affiliated with Altaris and is not subject to a financing contingency.
Simulations Plus co-founder and director Dr. Walter Woltosz has entered into a voting and support agreement with Altaris, agreeing to vote all shares beneficially owned by him in favor of the transaction.
Upon completion, Simulations Plus will become a privately held subsidiary of Altaris, and its common stock will no longer trade on the Nasdaq Stock Exchange. The company’s headquarters is expected to remain in Research Triangle Park, North Carolina.
Support: Morgan Stanley is serving as exclusive financial advisor to Simulations Plus, and Procopio Cory Hargreaves & Savitch is serving as legal counsel. Truist Securities and J.P. Morgan Securities are acting as financial advisors to Altaris, while Bass, Berry & Sims and Kirkland & Ellis are serving as legal counsel.
