Background:

Simulations Plus is a software company serving the pharmaceutical, biotechnology, and chemical industries. In June 2024, the Company acquired Pro-ficiency Holdings, Inc. and stated that the acquisition doubled the Company’s total addressable market to $8 billion.

On June 11, 2025, Simulations Plus announced preliminary third-quarter fiscal 2025 revenue and updated its full-year fiscal 2025 revenue outlook, 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 third-quarter fiscal 2025 results, including a net loss of $67.3 million and a $77.2 million non-cash impairment charge. The following day, the Company disclosed that it had dismissed its auditor, Grant Thornton LLP. Simulations Plus stated that certain matters involving segment reporting, reporting-unit determinations, and internal control over financial reporting could not be finalized in time for its Form 10-Q. Grant Thornton disagreed with the Company’s characterization and stated that it had identified and communicated matters related to segment reporting, reporting-unit determinations, and internal control over financial reporting, and that those matters “were not resolved to our satisfaction” as of its termination. On this news, shares fell nearly 26%, from $17.47 to $12.97 per share.
