Effect of Convertible Notes on Diluted EPS (Effective Q2 2025) * The Company is required to settle the principal amount of the 2029 Convertible Notes in cash,and has the option to settle the excess above principal in any combination of cash or shares. As such, only “in-the-money” shares above the implied conversion price of $29.22 are added to the diluted share count, and there is no interest expense add-back to the numerator for purposes of calculating diluted EPS. 2029 Convertible Notes (GAAP and Non-GAAP)* Average Stock Price per Common Share Incremental Dilutive Shares (in thousands) $29.00 - $30.00 205 $31.00 452 $32.00 684 $33.00 902 $34.00 1,106 $35.00 1,300 $36.00 1,482 $37.00 1,655 $38.00 1,818 $39.00 1,974 $40.00 2,121 $41.00 2,261 $42.00 2,395 $43.00 2,522 $44.00 2,644 $45.00 2,760

Note on Reconciliation Tables These tables include financial measures adjusted for the impact of certain items; these financial measures are therefore not calculated in accordance with U.S. generally accepted accounting principles (“GAAP”). These Non-GAAP financial measures exclude items such as: share-based compensation expense; charges relating to restructuring initiatives; non-cash asset impairments; certain other non-operating gains and losses; and acquisition-related items such as transaction costs, non-cash amortization of acquired intangible assets, incremental transaction-related compensation, and certain integration costs. These Non-GAAP financial measures may be different from Non-GAAP financial measures used by other companies. Non-GAAP financial measures should not be considered a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. By excluding these items, Non-GAAP financial measures are intended to facilitate meaningful comparisons to historical operating results, competitors' operating results, and estimates made by securities analysts. Management is evaluated on key performance metrics including Non-GAAP Operating Income, which is used to determine management incentive compensation as well as to forecast future periods. These Non-GAAP financial measures may be useful to investors in allowing for greater transparency of supplemental information used by management in its financial and operational decision-making. In addition, similar Non-GAAP financial measures have historically been reported to investors; the inclusion of comparable numbers provides consistency in financial reporting. Investors are encouraged to review the reconciliation of the Non-GAAP financial measures used in this news release to their most directly comparable GAAP financial measures.
