Executive Summary
Simulations Plus, Inc. has completed its acquisition by affiliates of Altaris, LLC, a healthcare-focused investment firm, for $18.50 per share in cash, with a total transaction value of approximately $376.8 million. As a result, the company's common stock is delisted from Nasdaq and will be deregistered, and the company becomes a privately held subsidiary of Altaris, combined with Chemical Computing Group (CCG). This marks the final step in the going-private transaction that was shareholder-approved in August 2026.
