Background of the Simulations Plus Investigation

On June 11, 2025, Simulations Plus issued preliminary third-quarter fiscal 2025 revenue results and revised its full-year fiscal 2025 revenue outlook. The Company attributed the updated outlook, in part, to market uncertainties affecting its business. Following this announcement, Simulations Plus stock declined more than 24%, falling from $26.44 per share to $20.05 per share.

Additional concerns emerged on July 14, 2025, when Simulations Plus reported its third-quarter fiscal 2025 financial results. The Company disclosed a net loss of $67.3 million, which included a $77.2 million non-cash impairment charge. Simulations Plus later announced that it had dismissed Grant Thornton LLP as its independent registered public accounting firm.

In connection with that disclosure, Simulations Plus stated that certain issues relating to segment reporting, reporting-unit determinations, and internal control over financial reporting could not be completed in time for the Company’s Form 10-Q. Grant Thornton, however, disputed aspects of the Company’s description. The auditor stated that it had previously identified and communicated matters concerning segment reporting, reporting-unit determinations, and internal control over financial reporting, and that those matters “were not resolved to our satisfaction” as of the date Grant Thornton was terminated.

Following these disclosures, Simulations Plus shares fell nearly 26%, declining from $17.47 per share to $12.97 per share.
