Non-GAAP Financial Measures Mylan is not providing forward looking information for U.S. GAAP reported financial measures or a quantitative reconciliation of forward-looking non-GAAP financial measures to the most directly comparable U.S. GAAP measure because it is unable to predict with reasonable certainty the ultimate outcome of certain significant items without unreasonable effort. These items include, but are not limited to, acquisition-related expenses, including integration, restructuring expenses, asset impairments, litigation settlements and other contingencies, including changes to contingent consideration and certain other gains or losses. These items are uncertain, depend on various factors, and could have a material impact on U.S. GAAP reported results for the relevant period. The stated forward-looking non-GAAP financial measure, ≤ 2.5x sustained leverage target, is based on the ratio of (i) targeted on l g-term average debt, and (ii) targeted long-term Credit Agreement Adjusted EBITDA. However, the Company has not quantified future amounts to develop the target but has stated its goal to manage long-term average debt and adjusted earnings and EBITDA over time in order to generally maintain the target. This target does not reflect Company guidance. For the quarter ended March 31, 2020, Mylan’s Credit Agreement Adjusted EBITDA was based on the sum of (i) Mylan’s adjusted EBITDA for the quarters ended June 30, 2019, September 30, 2019, December 31, 2019 and March 31, 2020 and (ii) certain adjustments permitted to be included in Credit Agreement Adjusted EBITDA as of March 31, 2020 pursuant to the revolving credit facility dated as of July 27, 2018 (as amended, supplemented or otherwise modified from time to time), among Mylan Inc., as borrower, the Company, as guarantor, certain affiliates and subsidiaries of the Company from time to time party thereto as guarantors, each lender from time to time party thereto and Bank of America, N.A., as administrative agent (the “Credit Agreement”). For the quarter ended March 31, 2020, Mylan calculated adjusted EBITDA as U.S. GAAP net earnings (loss) adjusted for clean energy investments pre-tax loss, income tax provision (benefit), interest expense and depreciation and amortization (to get to EBITDA) and further adjusted for share-based compensation expense, litigation settlements and other contingencies, net and restructuring, acquisition related and other special items to get to adjusted EBITDA. References to free cash flows are to U.S. GAAP net cash provided by operating activities minus capital expenditures. Adjusted EBITDA margin is calculated as adjusted EBITDA divided by total revenues. Historical Mylan non-GAAP financial measures may not be directly comparable to future non-GAAP financial measures that may be used by the combined company. This presentation includes the presentation and discussion of certain financial information that differs from what is reported under U.S. GAAP. These non-GAAP financial measures, including, but not limited to, leverage target, free cash flow, adjusted EBITDA, adjusted EBITDA margin, 2020E EBITDA margin, average estimated gross debt to 2020E EBITDA and total enterprise value to 2020E EBITDA are presented in order to supplement investors’ and other readers’ understanding and assessment of the financial performance of Mylan. Management uses these measures internally for forecasting, budgeting, measuring its operating performance, and incentive-based awards. Primarily due to acquisitions and other significant events which may impact comparability of our periodic operating results, Mylan believes that an evaluation of its ongoing operations (and comparisons of its current operations with historical and future operations) would be difficult if the disclosure of its financial results was limited to financial measures prepared only in accordance with U.S. GAAP. We believe that non-GAAP financial measures are useful supplemental information for our investors and when considered together with our U.S. GAAP financial measures and the reconciliation to the most directly comparable U.S. GAAP financial measure, if applicable, provide a more complete understanding of the factors and trends affecting our operations. In addition, the Company believes that including EBITDA and supplemental adjustments applied in presenting adjusted EBITDA and Credit Agreement Adjusted EBITDA pursuant to our Credit Agreement is appropriate to provide additional information to investors to demonstrate the Company’s ability to comply with financial debt covenants and assess the Company’s ability to incur additional indebtedness. The Company also believes that adjusted EBITDA better focuses management on the Company’s underlying operational results and true business performance and, beginning in 2020, is used, in part, for management’s incentive compensation. Investors and other readers are encouraged to review the related U.S. GAAP financial measures and, if applicable, the reconciliations of the non-GAAP measures to their most directly comparable U.S. GAAP measures, and investors and other readers should consider non- GAAP measures only as supplements to, not as substitutes for or as superior measures to, the measures of financial performance prepared in accordance with U.S. GAAP. 4Non-GAAP Financial Measures Mylan is not providing forward looking information for U.S. GAAP reported financial measures or a quantitative reconciliation of forward-looking non-GAAP financial measures to the most directly comparable U.S. GAAP measure because it is unable to predict with reasonable certainty the ultimate outcome of certain significant items without unreasonable effort.
