25 End Notes: Non-GAAP Financial Measures In this presentation, we sometimes use information derived from consolidated and segment financial information that may not be presented in our financial statements or prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). Certain of these financial measures are considered not in conformity with GAAP (“non-GAAP financial measures”) under the United States Securities and Exchange Commission (“SEC”) rules. Specifically, we have referred to the following non- GAAP financial measures: • Adjusted Net Income • Adjusted EBITDA • Adjusted EBITDA Margin • Adjusted Gross Margin • Adjusted Gross Margin % • Net Debt • Net Leverage Ratio We define Adjusted Net Income, which is a non-GAAP financial measures, as net income (loss) excluding the impact of non-cash amortization charges, impairments, severance and restructuring costs (benefits), inventory step-up provision, acquisition and divestiture costs, loss on assets held for sale, contingent consideration milestones, changes in fair value of financial instruments, stock-based compensation expense, loss on debt extinguishment, other, net, and tax effects. In the first quarter of 2026 we revised our calculation of these measures to exclude the impact of stock-based compensation expense, as this is a non-cash expense that is not related to our operating performance. We use Adjusted Net Income to assess total Company operating performance on a consistent basis. We believe that this non-GAAP financial measures, when considered together with our GAAP financial results and GAAP financial measures, provide management and investors with an additional understanding of our business operating results, including underlying trends. We define Adjusted EBITDA, which is a non-GAAP financial measure, as net income (loss) before depreciation and amortization, income taxes, total interest expense, net, impairments, inventory step-up provision, changes in fair value of financial instruments, severance and restructuring costs (benefits), acquisition and divestiture costs, loss on assets held for sale, contingent consideration milestones, stock-based compensation expense, loss on debt extinguishment, impairments, and other, net. We define Adjusted EBITDA Margin, which is a non-GAAP financial measure, as Adjusted EBITDA divided by Total Revenues. In the first quarter of 2026 we revised our calculation of these measures to exclude the impact of stock-based compensation expense, as this is a non-cash expense that is not related to our operating performance. We believe that these non-GAAP financial measures, when considered together with our GAAP financial results and GAAP financial measures, provide management and investors with a more complete understanding of our operating results, including underlying trends. In addition, EBITDA is a common alternative measure of operating performance used by many of our competitors. It is used by investors, financial analysts, rating agencies and others to value and compare the financial performance of companies in our industry, although it may be defined differently by different companies. Therefore, we also believe that this non-GAAP financial measure, considered along with corresponding GAAP financial measures, provides management and investors with additional information for comparison of our operating results with the operating results of other companies.
26 End Notes: Non-GAAP Financial Measures (Continued) We define Adjusted Gross Margin, which is a non-GAAP financial measure, as Gross Margin, excluding the impact of intangible asset amortization, stock-based compensation expense, severance and restructuring costs (benefits) and inventory step-up provision. We define Adjusted Gross Margin %, which is a non-GAAP financial measure, as Adjusted Gross Margin as a percentage of Products and services sales, net. In the first quarter of 2026 we revised our calculation of these measures to exclude the impact of stock-based compensation expense, as this is a non-cash expense that is not related to our operating performance. We define Net Debt, which is a non-GAAP financial measure, as our total debt less our cash and cash equivalents. We believe this non-GAAP financial measure, when considered together with our GAAP financial results, provides management and investors with an additional understanding of the Company's ability to pay its debts. We define Net Leverage Ratio, which is a non-GAAP financial measure, as our Net Debt divided by our Trailing Twelve Month Adjusted EBITDA. We believe this non-GAAP financial measure, when considered together with our GAAP financial results, provides management and investors with an additional understanding of the Company's current borrowing capabilities. Non-GAAP financial measures are not defined in the same manner by all companies and may not be comparable with other similarly titled measures of other companies. The determination of the amounts that are excluded from these non-GAAP financial measures are a matter of management judgment and depend upon, among other factors, the nature of the underlying expense or income amounts. Because non-GAAP financial measures exclude the effect of items that will increase or decrease the Company’s reported results of operations, management strongly encourages investors to review the Company’s consolidated financial statements and publicly filed reports in their entirety. For additional information on the non-GAAP financial measures noted here, please refer to the reconciliation tables provide in the Appendix to this presentation as well as the associated press release which can be found on the Company’s website at www.emergentbiosolutions.com.
