Reconciliation of Non-GAAP Measures

Three Months Ended December 31

(Millions) (Unaudited)

Overview

The Company reports its financial results in accordance with accounting principles generally accepted in the United States (referred to in this release as in accordance with "GAAP" or "reported" results). The Company also refers to and presents certain additional non-GAAP financial measures, within the meaning of Regulation G and item 10(e) Regulation S-K in accordance with the Securities Exchange Act of 1934. These measures are: non-GAAP revenue, adjusted operating income (loss), adjusted operating margin, adjusted income, net of tax and adjusted earnings per share (EPS). The Company has included reconciliations of these non-GAAP financial measures to the most directly comparable financial measure calculated in accordance with GAAP in the following tables.

The Company believes these non-GAAP financial measures provide useful supplemental information that enables investors to better compare the Company’s performance across periods. Management also uses these measures internally to assess the operating performance of its businesses and to decide how to allocate resources. However, investors should not consider these non-GAAP measures in isolation from, or as a substitute for, the financial information that the Company reports in accordance with GAAP. The Company's non-GAAP measures include adjustments that reflect how management views its businesses, and may differ from similarly titled non-GAAP measures presented by other companies.

In the first quarter of 2025, the Company changed its methodology to report adjusted operating income (loss), adjusted income, net of tax and adjusted EPS to exclude the impact of intangible amortization and other net benefit credits. Prior year results are presented using the new methodology for comparative purposes.

Adjusted Operating Income (Loss) and Adjusted Operating Margin

Adjusted operating income (loss) is calculated by excluding the impact of certain noteworthy items and identified intangible amortization expense from the Company's GAAP operating income (loss). The following tables reconcile adjusted operating income (loss) to GAAP operating income (loss) on a consolidated and reportable segment basis for the three and twelve months ended December 31, 2025 and 2024. The following tables also present adjusted operating margin. For the three and twelve months ended December 31, 2025 and 2024, adjusted operating margin is calculated by dividing the sum of adjusted operating income by consolidated or segment adjusted revenue. The Company's adjusted revenue used in the determination of adjusted operating margin is calculated by excluding the impact of certain noteworthy items from the Company's GAAP revenue.

Reconciliation of Non-GAAP Measures

Three Months Ended December 31

(Millions) (Unaudited)

Non-GAAP revenue isolates the impact of foreign exchange rate movements and certain transaction-related items from the current period GAAP revenue. The non-GAAP revenue measure is presented on a constant currency basis, excluding the impact of foreign currency fluctuations. The Company isolates the impact of foreign exchange rate movements period over period, by translating the current period foreign currency GAAP revenue into U.S. Dollars based on the difference in the current and corresponding prior period exchange rates. Similarly, certain other items such as acquisitions and dispositions, including transfers among businesses, may impact period over period comparisons of revenue and are consistently excluded from current and prior period GAAP revenues for comparability purposes. Percentage changes, referred to as non-GAAP underlying revenue, are calculated by dividing the period over period change in non-GAAP revenue by the prior period non-GAAP revenue.

The following table provides the reconciliation of GAAP revenue to non-GAAP revenue:
