SAN DIEGO, July 28, 2026 /PRNewswire/ -- Robbins LLP announces that it is investigating Simulation Plus, Inc. (NASDAQ: SLP) to determine whether certain officers and directors violated securities laws or breached fiduciary duties owed to shareholders.
The investigation concerns whether Simulation Plus made materially false or misleading statements or omitted material information regarding its financial reporting, internal controls, and business outlook.
Investors who purchased Simulation Plus securities and suffered losses may have legal rights.
Why Is Robbins LLP Investigating Simulation Plus?
The investigation focuses on whether Simulation Plus failed to disclose material information concerning its financial reporting, revenue outlook, and internal controls before investors suffered significant losses.
- On June 11, 2025, the Company announced preliminary third-quarter fiscal 2025 revenue and lowered its full-year fiscal 2025 revenue outlook, citing market uncertainty.
- Following the announcement, the stock price declined more than 24%, from $26.44 to $20.05 per share.

- On July 15, 2025, Simulation Plus disclosed that it had dismissed Grant Thornton LLP as its independent auditor.
- The Company further stated that issues involving segment reporting, reporting-unit determinations, and internal control over financial reporting prevented timely completion of its Form 10-Q.
Robbins LLP is investigating whether investors were adequately informed of these matters.
