Background:
Simulations Plus is a software company serving the pharmaceutical, biotechnology, and chemical industries. In June 2024, the Company acquired Pro-ficiency Holdings, Inc., promoting the integration as a key driver of growth and claiming it would double the Company’s total addressable market. Simulations Plus also assured investors that its internal controls over financial reporting were effective.

However, on June 11, 2025, Simulations Plus announced disappointing preliminary 3Q 2025 results, citing “market uncertainties” as headwinds. On this news, the Company’s stock fell over 24%, from $26.44 to $20.05 per share. Then, on July 14, 2025, Simulations Plus reported a $77.2 million charge “related to prior acquisitions,” and the following day disclosed that it had dismissed its auditor, Grant Thornton LLP. Simulations Plus acknowledged unresolved issues with segment reporting and internal controls, while Grant Thornton publicly disagreed with the Company’s characterization, stating that concerns it raised “were not resolved to our satisfaction.” On this news, shares fell nearly 26%, from $17.47 to $12.97 per share.
