Note on Non-GAAP Financial Measures
As used in this press release the term "reported" refers to measures under accounting principles generally accepted in the United States ("GAAP"). The term "adjusted" refers to non-GAAP operating performance measures that exclude special items such as restructuring and integration charges, amortization expense, excess tax benefits ( ETB ) associated with stock-based compensation, gains and losses associated with changes in the carrying value of our strategic investments and other items.
Non-GAAP adjusted measures are presented because management believes those measures are useful adjuncts to GAAP results. Non-GAAP adjusted measures should not be considered as an alternative to the corresponding measures determined under GAAP. Management may use these non-GAAP measures to evaluate our performance period over period and relative to competitors, to analyze the underlying trends in our business, to establish operational budgets and forecasts and for incentive compensation purposes. We believe that these non-GAAP measures are useful to investors and analysts to evaluate our performance period over period and relative to competitors, as well as to analyze the underlying trends in our business and to assess our performance. The additional tables attached below include reconciliations of non-GAAP adjusted measures to GAAP measures.

(a)For both the three months ended March 31, 2026 and 2025, the pre-tax impact represents costs primarily associated with workforce reductions and integration costs incurred in connection with further restructuring and integrating our business. The following table summarizes the pre-tax impact of restructuring and integration charges on our consolidated statements of operations

| Cost of services | $ | 1 | $ | 6 | |||||||
| Selling, general and administrative | 6 | 13 | |||||||||
| Operating income | $ | 7 | $ | 19 |
(b)For both the three months ended March 31, 2026 and 2025, the pre-tax impact primarily represents a loss associated with the change in the fair value of the contingent consideration accrual associated with previous acquisitions, recorded in other operating expense, net.
(c)For the three months ended March 31, 2026, the pre-tax impact represents losses associated with changes in the carrying value of our strategic investments, principally recorded in equity in earnings of equity method investees, net of taxes.
(d)The three months ended March 31, 2025 includes pre-tax gains of $8 million, recorded in equity in earnings of equity method investees, net of taxes, principally consisting of a non-recurring gain related to a lease.
(e)For restructuring and integration charges, other gains charges, gains and losses on investments, and amortization expense, income tax impacts, where recorded, were primarily calculated using combined statutory income tax rates of 25.5% for both 2026 and 2025. No income tax impact was recorded on losses associated with the change in the fair value of the contingent consideration accrual associated with previous acquisitions.
3)The outlook for adjusted diluted EPS represents management's estimates for the full year 2026 before the impact of special items. Further impacts to earnings related to special items may occur throughout 2026. Additionally, the amount of ETB is dependent upon employee stock option exercises and our stock price, which are difficult to predict. The following table reconciles our 2026 outlook for diluted EPS under GAAP to our outlook for adjusted diluted EPS

(a)Represents estimated pre-tax charges of $16 million primarily associated with workforce reductions and integration costs incurred in connection with further restructuring and integrating our business. Income tax benefits were primarily calculated using a combined statutory income tax rate of 25.5%.
(b)Represents estimated pre-tax amortization expenses of $149 million. Income tax benefits were primarily calculated using a combined statutory income tax rate of 25.5%.
(c)Principally represents estimated pre-tax net losses of $10 million associated with the increase in the fair value of the contingent consideration accrual associated with previous acquisitions. Such estimate is subject to the risks and uncertainties discussed in the Forward Looking Statements section above. No income tax benefits are recorded on the changes associated with the contingent consideration accrual.
(d)Income tax impacts were calculated using a combined statutory income tax rate of 25.5%.
