**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 attached 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 both the three and twelve months ended December 31, 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;Operating income | $16 | $17 | $53 | $62 |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The pre-tax impact for all periods relates to the change in the fair value of the contingent consideration accrual associated with previous acquisitions. Such impact is recorded in other operating (income) expense, net in our consolidated statement of operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)The pre-tax impact for the three and twelve months ended December 31, 2025 primarily includes $7 million of charges to earnings related to legal matters (recorded in selling, general and administrative expenses in our consolidated statement of operations). The pre-tax impact for the twelve months ended December 31, 2025 also includes an impairment charge of $29 million on certain long-lived assets related to the exit of a business and $15 million of charges to earnings related to legal matters. Such amounts are recorded in other operating (income) expense, net in our consolidated statement of operations. The following table summarizes the pre-tax impact of these other items on our consolidated statement of operations:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Three Months Ended December 31,** | **Three Months Ended December 31,** | **Twelve Months Ended December 31,** | **Twelve Months Ended December 31,** |

| &nbsp;&nbsp;&nbsp;Operating income | $8 | $2 | $52 | $4 |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)For all periods presented, the pre-tax impact represents gains and losses associated with changes in the carrying value of our strategic investments, principally recorded in other income, net.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)The twelve months ended December 31, 2025 includes 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 associated with the retention of employees. Also, the twelve months ended December 31, 2025 includes a pre-tax gain, recorded in equity in earnings of equity method investees, net of taxes, representing a non-recurring gain related to a lease. The twelve months ended December 31, 2024 principally includes a non-recurring $8 million pre-tax gain, recorded in other income, net, associated with a foreign exchange forward contract utilized in conjunction with an acquisition. The following table summarizes the pre-tax impact of these other gains on our consolidated statements of operations:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Three Months Ended December 31,** | **Three Months Ended December 31,** | **Twelve Months Ended December 31,** | **Twelve Months Ended December 31,** |

| Other income, net | $— | $3 | $— | $12 |
| Equity in earnings of equity method investees, net of taxes | $— | $— | $8 | $— |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)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. No income tax impact was recorded on gains/losses associated with the change in the fair value of the contingent consideration accrual associated with previous acquisitions. The three

------

and twelve months ended December 31, 2025 include $5 million of income tax expense related to the disposal of a business.

3)For the twelve months ended December 31, 2025, we repurchased 2.5 million shares of our common stock for $452 million. As of December 31, 2025, $0.4 billion remained available under our share repurchase authorization.

4)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:

---

| | | |
|:---|:---|:---|
| | **Low** | **High** |
| Diluted EPS | $9.45 | $9.65 |
| Restructuring and integration charges (a) | 0.07 | 0.07 |
| Amortization expense (b) | 1.03 | 1.03 |
| Other charges (c) | 0.11 | 0.11 |
| ETB | (0.16) | (0.16) |
| Adjusted diluted EPS | $10.50 | $10.70 |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)Represents estimated pre-tax charges of $12 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%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Represents estimated pre-tax amortization expenses of $155 million. Income tax benefits were primarily calculated using a combined statutory income tax rate of 25.5%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Principally includes estimated pre-tax net charges of $12 million associated with the estimated change 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 impacts were recorded on the change associated with the contingent consideration accrual.
