PERRIGO COMPANY PLC

ITEM 2.02. Results of Operations and Financial Condition On August 5, 2026, Perrigo Company plc (the “Company”) released earnings for the second quarter ended June 27, 2026. The press release related to the Company’s earnings is attached as Exhibit 99.1. The Company provides non-GAAP financial measures as additional information that it believes is useful to investors and analysts in evaluating the performance of the Company's ongoing operating trends, facilitating comparability between periods and, where applicable, with companies in similar industries and assessing the Company's prospects for future performance. These non-GAAP financial measures exclude items, such as amortization expense, unusual litigation, impairment charges, restructuring charges, and acquisition and integration-related charges, that by their nature affect comparability of operational performance or that we believe obscure underlying business operational trends. The intangible asset amortization excluded from these non-GAAP financial measures represents the entire amount recorded within the Company’s GAAP financial statements and is excluded because the amortization, unlike the related revenue, is not affected by operations of any particular period unless an intangible asset becomes impaired or the estimated useful life of an intangible asset is revised. The revenue generated by the associated intangible assets has not been excluded from the related non-GAAP financial measure. The non-GAAP measures the Company provides are consistent with how management analyzes and assesses the operating performance of the Company, and disclosing them provides investor insight into management’s view of the business. Management uses these adjusted financial measures for planning and forecasting in future periods, and evaluating segment and overall operating performance. In addition, management uses certain of the profit measures as factors in determining compensation. Non-GAAP measures related to profit measurements, which may include adjusted gross profit, adjusted net income, adjusted operating income, adjusted diluted earnings per share, adjusted gross margin, constant currency net sales, adjusted operating margin and adjusted effective tax rate are useful to investors as they provide them with supplemental information to enhance their understanding of the Company’s underlying business performance and trends, and enhance the ability of investors and analysts to compare the Company’s period-to-period financial results. Management believes that adjusted gross margin and adjusted operating margin are useful to investors, in addition to the reasons discussed above, by allowing them to more easily compare and analyze trends in the Company’s peer business group and assisting them in comparing the Company’s overall performance to that of its competitors. The Company also discloses net sales growth excluding the impact of currency on an organic basis. In addition, the Company presents non‑GAAP measures for 'Core' Perrigo, reflecting its go‑forward business and excluding infant formula currently under strategic review and previously announced divestitures. Core measures may include Core net income, Core net sales, Core organic net sales, Core gross profit, Core operating income, Core diluted earnings per share, Core gross margin, and Core operating margin, including on an organic, constant‑currency basis. Management believes these measures provide greater consistency in financial reporting and facilitate meaningful comparisons of underlying operating results and acquisition and divestiture activity. The Company cannot reconcile its ‘All In’ or ‘Core’ expected organic net sales growth, adjusted gross margin, adjusted operating margin, adjusted earnings per share, adjusted diluted earnings per share, or adjusted effective tax rate to the most directly comparable GAAP measures under "Fiscal Year 2026 Outlook from Continuing Operations" without unreasonable effort because certain items that impact net income and other reconciling metrics are out of the Company's control and/or cannot be reasonably predicted at this time. These items include, but are not limited to, uncertainty of non-recurring infant formula related charges and timing and amount of restructuring charges and the income tax effects of these items or other income tax-related events. The Company believes these supplemental financial measures provide investors with consistency in financial reporting, enabling meaningful comparisons of past and present underlying operating results, and also facilitate analysis of the Company’s operating performance and acquisition and divestiture trends. Investors should consider the non-GAAP measures provided in the attached earnings release in conjunction with, and not in lieu of, the Company's reported financial statements in accordance with GAAP.
