Updates fiscal 2025 revenue guidance range

Third quarter fiscal 2025 full results to be released on July 2, 2025, with conference call at 5 p.m. ET

Simulations Plus, Inc. (Nasdaq: SLP) (“Simulations Plus” or the “Company”), a leading provider of cheminformatics, biosimulation, simulation-enabled performance and intelligence solutions, and medical communications to the biopharma industry, today announced preliminary revenue for its third fiscal quarter and updated its full year 2025 revenue guidance.

• The Company expects to report third quarter fiscal 2025 revenue in the range of between $19 million and $20 million
• Full year fiscal 2025 revenue is expected to range between $76 million and $80 million

The third quarter fiscal 2025 revenue range set forth above is preliminary, unaudited, based on currently available information, and subject to adjustment in the final financial statements to be filed with the Company’s Quarterly Report on Form 10-Q for the third quarter fiscal 2025, expected to be filed July 2, 2025.

Full year fiscal 2025 revenue guidance may also be adjusted when the Company reports third quarter fiscal 2025 results.

“Market uncertainties surrounding future funding, drug pricing and potential tariffs are creating significant headwinds for both our pharmaceutical and biotech clients, resulting in budget reductions, project cancellations, and delays that are more pronounced than what we have experienced over the past two years,” said Shawn O’Connor, Chief Executive Officer of Simulations Plus. “While our software segment has remained relatively resilient, given its role as critical infrastructure in drug development programs, demand for services has proven more sensitive to market volatility and is coming in below our expectations.

“To better position the Company for long-term alignment with our clients, we recently announced a strategic reorganization—transitioning from a business unit structure to a functionally driven operating model. We also made key leadership appointments to enhance client engagement and elevate our sales and marketing capabilities.

“These actions mark the final phase of a multi-year transformation aimed at streamlining operations, unlocking synergies across teams, and concentrating our resources on the most promising growth opportunities. We believe the new organizational structure will also foster greater collaboration through centralized product and technology development, contributing to accelerated delivery of software enhancements, platform integration, and AI advancements.

“Finally, these changes are expected to improve operational efficiency and better position us for sustainable and profitable long-term growth. Looking ahead, we remain optimistic about the future of predictive analytics in biosimulation and clinical operations. These capabilities are essential to helping our clients achieve greater efficiency and success, and we are proud to be a long-standing partner and innovation leader in this space,” concluded O’Connor.
