The transaction is progressing along its previously disclosed path. Simulations Plus announced the Altaris acquisition on June 16, 2026, at $18.50 per share in cash, with closing expected in the fourth quarter of 2026. The HSR waiting period was a required closing condition, so its expiration removes one U.S. antitrust hurdle but does not change the deal economics. (Merger update)
The filing clears one gate, not the deal itself. The company still requires shareholder approval and certain regulatory approvals in France before closing. (Merger update) That means the filing reduces execution risk incrementally, but it is not a closing announcement or a new offer.
Versus expectations, this is a procedural confirmation rather than a surprise. The direction was already established when the merger was announced and the proxy was filed on July 22, 2026; today’s update mainly confirms that the transaction remains on track. The net read is therefore neutral: one standard condition has been satisfied, while the remaining approval risk is still open.
