SUPPLEMENTARY INFORMATION
RECONCILIATION OF GAAP TO NON-GAAP FINANCIAL MEASURES
(Unaudited)

This earnings release includes “adjusted net income (non-GAAP)” and “adjusted net income per diluted share (non-GAAP)”, which are financial measures that are not in accordance with U.S. generally accepted accounting principles (“GAAP”), since they exclude a charge for EC-related claims. These measures differ from the most directly comparable measures calculated in accordance with GAAP and may not be comparable to similarly titled non-GAAP financial measures used by other companies.

On July 19, 2016, the European Commission (EC) concluded its investigation of all major European truck manufacturers and reached a settlement with the Company. Following the settlement, legal proceedings seeking damages were filed against all major European truck manufacturers. In the first quarter of 2023, the Company recorded a pre-tax charge of $600.0 ($446.4 after-tax) for the estimable total cost. Several courts have issued judgments; some have been favorable while others have been unfavorable and have been appealed. The Company has settled with the majority of claimants and continues to pursue appropriate resolutions. Due to higher settlement costs, the Company updated its estimate and recorded an additional pre-tax charge of $350.0 ($264.5 after-tax) for the total estimable remaining costs in Interest and other (income) expenses, net in the first quarter of 2025.

The Company utilizes these non-GAAP measures to allow investors and management to evaluate operating trends by excluding a significant charge that is not representative of company performance.

Reconciliations from the most directly comparable GAAP measures to adjusted net income (non-GAAP) and adjusted net income per diluted share (non-GAAP) are as follows:
