Shareholder rights law firms Robbins LLP>>> and Johnson Fistel>>> are investigating Simulations Plus>>> for potential securities law violations and breaches of fiduciary duties by its officers and directors. This follows Simulations Plus>>>'s announcement of reduced full-year fiscal 2025 revenue guidance, a significant net loss of $67.3 million including a $77.2 million non-cash impairment charge, and the dismissal of its auditor, Grant Thornton Bharat>>>. Grant Thornton Bharat>>> subsequently filed a letter with the SEC, disagreeing with Simulations Plus>>>'s characterization of the dismissal and stating that certain matters related to segment reporting and internal controls were not resolved to its satisfaction. These events have led to substantial declines in Simulations Plus>>>'s stock price.
