Reconciliations of GAAP to Non-GAAP Financial Measures (In thousands, except per share amounts) (Unaudited) Forecasted Diluted Earnings Per Share Year Ended December 31, 2025 Low High Diluted earnings per share (GAAP) $ 6.14   $ 6.30   Pretax amortization of acquisition-related intangible assets 1.16   1.16   Income tax benefit on amortization of acquisition-related intangible assets (0.28) (0.28) Adjusted Diluted earnings per share (Non-GAAP) $ 7.02   $ 7.18   Use of Non-GAAP Financial Information The Company supplements its consolidated financial statements presented on a U.S. generally accepted accounting principles (“GAAP”) basis with certain non-GAAP financial information to provide investors with greater insight, increased transparency and allow for a more comprehensive understanding of the information used by management in its financial and operational decision-making. Reconciliation of non-GAAP measures to their most directly comparable GAAP measures are included in the accompanying financial tables. These non-GAAP financial measures should be considered in addition to, and not as a replacement for, or superior to, the comparable GAAP measure, and may not be comparable to similarly titled measures reported by other companies. The Company believes that these measures provide useful information to investors by reflecting additional ways of viewing AMETEK’s operations that, when reconciled to the comparable GAAP measure, helps our investors to better understand the long-term profitability trends of our business, and facilitates easier comparisons of our profitability to prior and future periods and to our peers.
