**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, impairment charges 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 below include reconciliations of non-GAAP adjusted measures to GAAP measures.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)For each of the three and six months ended June 30, 2025 and 2024, 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:

---

| | | | | |
|:---|:---|:---|:---|:---|

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)For both the three and six months ended June 30, 2025, the pre-tax impact primarily represents a $24 million impairment charge on certain long-lived assets related to the potential exit of a business. Additionally, each of the three and six months ended June 30, 2025 and June 30, 2024 include losses associated with the change in the fair value of the contingent consideration accrual associated with previous acquisitions. The following table summarizes the pre-tax impact of these other charges on our consolidated statements of operations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)For each of the three and six months ended June 30, 2025 and 2024, the pre-tax impact represents gains and losses associated with changes in the carrying value of our strategic investments, recorded in equity in earnings of equity method investees, net of taxes, and other income, net.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)The three and six months ended June 30, 2025 include a $46 million pre-tax gain, recorded in other operating (income) expense, net, from a payroll tax credit under the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") associated with the retention of employees. Additionally, the six months ended June 30, 2025 includes an $8 million gain, recorded in equity in earnings of equity method investees, net of taxes, representing a non-recurring gain related to a lease.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 2025 and 2024.

3)The outlook for adjusted diluted EPS represents management's estimates for the full year 2025 before the impact of special items. Further impacts to earnings related to special items may occur throughout 2025. 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 2025 outlook for diluted EPS under GAAP to our outlook for adjusted diluted EPS:

---

| | | |
|:---|:---|:---|
| | **Low** | **High** |
| Diluted EPS | $8.60 | $8.80 |
| Restructuring and integration charges (a) | 0.24 | 0.24 |
| Amortization expense (b) | 1.03 | 1.03 |
| Other charges (c) | 0.27 | 0.27 |
| Other gains (d) | (0.36) | (0.36) |
| Gains and losses on investments | (0.01) | (0.01) |
| ETB | (0.14) | (0.14) |
| Adjusted diluted EPS | $9.63 | $9.83 |
