Simulations Plus Announces Expiration of Hart-Scott-Rodino Waiting Period for Pending Acquisition by Altaris

Simulations Plus (SLP) announced expiration of its Hart-Scott-Rodino waiting period in connection with Altaris acquisition, a procedural regulatory milestone in an already-announced transaction. The HSR clearance removes one of several closing conditions but represents routine antitrust review completion rather than a new catalyst or material deal development.

This disclosure is administrative in nature—HSR clearance was expected and widely anticipated for a transaction of this profile. The announcement confirms regulatory progress but does not alter the fundamental investment thesis around SLP or introduce new information about deal economics, pricing, or timing. Shareholders had pricing and risk embedded in prior announcements.

The expiration satisfies mandatory antitrust process requirements under 1976 legislation. Remaining closing conditions—typically financing, other regulatory approvals, and shareholder consent—remain in play. No new deal risk or acceleration has been flagged by the Company's disclosure language.

Sector implication: Health Care software and services benefit from consolidation and private-equity backing (Altaris is a dedicated healthcare PE platform), but this particular filing adds no incremental market signal. Sentiment remains neutral pending final close.
