1 Earnings Call – Q2 - FY25 April 3, 2025

Except for historical information, the matters discussed in this presentation are forward-looking statements that involve risks and uncertainties. Words like “believe,” “will”, “can”, “expect,” “anticipate” and similar expressions (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. Forward looking statements contained in this press release include, but are not limited to, statements about expectations for the second half of 2025 and anticipated projections for fiscal year 2025. Factors that could cause or contribute to such differences include, but are not limited to: our ability to integrate our Adaptive Learning & Insights (ALI) and Medical Communications (MC) business units, our ability to meet our stated guidance, our ability to maintain our competitive advantages, acceptance of new software and improved versions of our existing software by our customers, the general economics of the pharmaceutical industry, general economic, political or geopolitical conditions and changes, 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. Non-GAAP Financial Measures This press release includes certain financial measures not presented in accordance with generally accepted accounting principles (“GAAP”) such as Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, and Adjusted Diluted EPS and certain ratios and other metrics derived there from. These non-GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing financial results. Therefore, these measures should not be considered in isolation or as an alternative to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP. You should be aware that the presentation of these measures may not be comparable to similarly-titled measures used by other companies. We believe (i) these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends; and (ii) that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in and in comparing financial measures with other similar companies, many of which present similar non- GAAP financial measures to investors. These non-GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP financial measures. Reconciliations of these non-GAAP measures to the most directly comparable GAAP measures are set forth in the appendix to this presentation. Safe Harbor Statement 2
