Why Is Johnson Fistel Investigating Simulations Plus?

On April 3, 2025, Simulations Plus reported financial results for the second quarter of fiscal 2025 and maintained full-year fiscal 2025 revenue guidance of $90 million to $93 million.

Then, on June 11, 2025, Simulations Plus announced preliminary third-quarter fiscal 2025 revenue results and reduced its full-year fiscal 2025 revenue guidance to a range of $76 million to $80 million. The Company attributed the revised outlook, in part, to market uncertainties affecting pharmaceutical and biotechnology customers, including budget reductions, project cancellations, and delays.

Following this announcement, Simulations Plus stock declined more than 24%, falling from $26.44 per share to $20.05 per share.

Additional Simulations Plus Disclosures

On July 14, 2025, Simulations Plus reported third-quarter fiscal 2025 financial results and disclosed a net loss of $67.3 million, or $3.35 per diluted share. The loss included a $77.2 million non-cash impairment charge.

The following day, Simulations Plus disclosed that its Audit Committee had dismissed Grant Thornton LLP as the Company’s independent registered public accounting firm. In the Company’s Form 8-K, Simulations Plus stated that certain matters relating to segment reporting, reporting-unit determinations, and internal control over financial reporting could not be finalized in time for the Company’s Quarterly Report on Form 10-Q.

Grant Thornton later filed a letter with the SEC disagreeing with aspects of Simulations Plus’ disclosure. In that letter, Grant Thornton stated that it had identified and communicated matters to management and the Audit Committee relating to 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.
