Management Commentary

"By successfully meeting our revised fiscal 2025 guidance, we have demonstrated Simulations Plus’ resilience and agility in navigating evolving market dynamics,” said Shawn O’Connor, CEO of Simulations Plus. “We delivered 13% revenue growth and achieved 8% growth in both adjusted EBITDA and adjusted EPS. Looking ahead to fiscal 2026, we anticipate low single-digit revenue growth at the mid-point of the guidance range, assuming current market conditions remain. Importantly, we believe we are well-positioned to capture upside should the spending environment improve for our pharmaceutical and biotech clients.”

“The demand environment remains cautious, but we believe adoption of cloud deployment, interoperability, and AI-driven workflows is accelerating across our customer base. Following our successful transition to a functionally optimized structure, our product and technology team is launching an ambitious product vision that links our validated modeling engines with cloud-scale compute, AI-assisted workflows, and a stronger compliance and identity framework. Cloud-scale performance for intensive modeling, AI copilots that simplify complex workflows, and federated data capabilities aligned with enterprise and regulatory expectations will cut cycle times, increase cross-product adoption, and open new enterprise opportunities — all while preserving the accuracy and scientific depth our customers depend on. With validated science at the core of every product, we believe Simulations Plus is well positioned to lead the next chapter of AI-enabled drug development. We look forward to sharing more of our integrated product vision at Investor Day in January, concluded O’Connor.”

Non-GAAP Financial Measures

This press release contains “non-GAAP financial measures,” which are measures that either exclude or include amounts that are not excluded or included in the most directly comparable measures calculated and presented in accordance with U.S. generally accepted accounting principles (“GAAP”).

A further explanation and reconciliation of these non-GAAP financial measures is included below and in the financial tables in this release.

The Company believes that the non-GAAP financial measures presented facilitate an understanding of operating performance and provide a meaningful comparison of its results between periods. The Company’s management uses non-GAAP financial measures to, among other things, evaluate its ongoing operations in relation to historical results, for internal planning and forecasting purposes and in the calculation of performance-based compensation. Adjusted EBITDA and Adjusted Diluted EPS represent measures that we believe are customarily used by investors and analysts to evaluate the financial performance of companies in addition to the GAAP
measures that we present. Our management also believes that these measures are useful in evaluating our core operating results. However, Adjusted EBITDA and Adjusted Diluted EPS are not measures of financial performance under accounting principles generally accepted in the United States of America and should not be considered an alternative to net income, operating income, or diluted EPS as indicators of our operating performance or to net cash provided by operating activities as a measure of our liquidity. We believe the Company’s Adjusted EBITDA and Adjusted Diluted EPS measures provide information that is directly comparable to that provided by other peer companies in our industry, but other companies may calculate non-GAAP financial results differently, particularly related to nonrecurring, unusual items.

Please note that the Company has not reconciled the adjusted EBITDA or adjusted diluted earnings per share forward-looking guidance included in this press release to the most directly comparable GAAP measures because this cannot be done without unreasonable effort due to the variability and low visibility with respect to costs related to acquisitions, financings, and employee stock compensation programs, which are potential adjustments to future earnings. We expect the variability of these items to have a potentially unpredictable, and a potentially significant, impact on our future GAAP financial results.

Adjusted EBITDA

Adjusted EBITDA represents net income excluding the effect of interest expense (income), provision (benefit) for income taxes, depreciation and amortization, equity-based compensation expense, loss (gain) on currency exchange, impairment charges, change in fair value of contingent consideration, reorganization expense, acquisition and integration expense and other items not indicative of our ongoing operating performance.

Adjusted Net Income and Adjusted Diluted EPS

Adjusted net income and adjusted diluted earnings per share exclude the effect of amortization, equity-based compensation expense, loss (gain) on currency exchange, impairment charges, change in fair value of contingent consideration, reorganization expense, acquisition and integration expense and other items not indicative of our ongoing operating performance as well as the income tax provision adjustment for such charges.

The Company excludes the above items because they are outside of the Company’s normal operations and/or, in certain cases, are difficult to forecast accurately.

Forward-Looking Statements

Except for historical information, the matters discussed in this press release are forward-looking statements that involve risks and uncertainties. Words like “believe,” “will”, “can”, “believe”, “expect,” “anticipate” and similar expressions (or the negative of such terms, as well as other words or expressions referencing future events, conditions or circumstances) mean that these are our best estimates as of this writing, but there can be no assurances that expected or anticipated results or events will actually take place, so our actual future results could differ significantly from those statements. These forward-looking statements are based on current assumptions and expectations that involve risks and uncertainties that could cause the actual results to differ materially from those expressed or implied. Factors that could cause or contribute to such differences include, but are not limited to: effectiveness of our new internal operational structure, our ability to maintain our competitive advantages and commercialize AI and cloud-enabled solutions, evolving regulatory and data privacy standards governing AI technologies, acceptance of new software and improved versions of our existing software by our customers, the general economics of the pharmaceutical industry, our ability to finance growth, our ability to continue to attract and retain highly qualified technical staff, market conditions, macroeconomic factors, and a sustainable market. Further information on our risk factors is contained in our quarterly, annual and current reports and filed with the U.S. Securities and Exchange Commission.
