“Our second quarter results reflected strong performance in both our software and services segments,” said Shawn O’Connor, Chief Executive Officer of Simulations Plus. “Total revenue increased 16%, driven by higher software revenues in our Clinical Pharmacology & Pharmacometrics (CPP) business unit and the Cheminformatics business unit, whose ADMET Predictor® platform continued to gain adoption and added another new Artificial Intelligence (AI) biotech customer in the second quarter. Services revenue growth was primarily driven by higher revenues in our Quantitative Systems Pharmacology (QSP) and Physiologically Based Pharmacokinetics (PBPK) business units.

“Since the beginning of calendar 2024, we have seen encouraging signs in biotech funding with notable strength from biotech companies that have candidates undergoing clinical trials. Regarding large pharmaceutical companies, funding continues to vary depending on their near-term direction and business outlook, but the overall market is healthier compared to a year ago. For the balance of 2024, we remain cautiously optimistic that demand for our comprehensive suite of modeling and simulation software products and services will continue to gain momentum as the funding environment improves.

“During the quarter, we also launched our corporate development initiative to intensify our focus on strategic investments and partnerships in early-state technology companies. While strategic acquisitions to complement

organic growth remain a priority, we believe there are hidden gems among early-stage companies developing high-potential technologies. We believe that our ability to identify and evaluate commercial applications for emerging technologies will complement our own R&D efforts and position Simulations Plus at the forefront of innovation.

“Our strong performance in the first half of the year, combined with market improvement, puts us on track to achieve our guidance for fiscal 2024. We entered the third quarter with a healthy pipeline and a solid balance sheet, and we are confident that Simulations Plus is firmly positioned to advance its critical role in drug development workflow. Our unwavering focus remains on delivering disciplined growth and achieving long-term returns for our shareholders.”

The Company’s Board of Directors declared a cash dividend of $0.06 per share of the Company’s common stock, payable on May 6, 2024, to shareholders of record as of April 29, 2024. The declaration of any future dividends will be determined by the Board of Directors each quarter and will depend on earnings, financial condition, capital requirements, and other factors.

Adjusted EBITDA

Adjusted EBITDA is defined as earnings (loss) before interest, taxes, depreciation and amortization, stock-based compensation, (gain) loss on currency exchange, any acquisition- or financial-transaction-related expenses, and any asset impairment charges. Currency exchange excluded represents the exchange rate fluctuations on the foreign currency denominated transactions. The impact of transactions in foreign currency represents the effect of converting revenue and expenses occurring in a currency other than the functional currency. 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 represents a measure that we believe is 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 Adjusted EBITDA is useful in evaluating our core operating results. However, Adjusted EBITDA is not a measure of financial performance under accounting principles generally accepted in the United States of America and should not be considered an alternative to net income or operating income as an indicator of our operating performance or to net cash provided by operating activities as a measure of our liquidity. The Company’s Adjusted EBITDA measure may not provide information that is directly comparable to that provided by other companies in its industry, as other companies in its industry may calculate non-GAAP financial results differently, particularly related to nonrecurring, unusual items.

Adjusted Diluted EPS

Adjusted diluted EPS is calculated based on net income excluding the impact of any acquisition- or financial-transaction-related expenses, any asset impairment charges, and tax provisions / benefits related to the previous items. 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 for future periods.

The Company believes that the use of non-GAAP measures helps investors to gain a better understanding of the Company’s core operating results and future prospects, consistent with how management measures and forecasts the Company’s performance, especially when comparing such results to previous periods or forecasts.
