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.

							(c)	For each of the three and nine months ended September 30, 2025 and 2024, the pre-tax impact represents gains and 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 nine months ended September 30, 2025 include a $46 million pre-tax gain, recorded in other operating 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 nine months ended September 30, 2025 include 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.  For the three and nine months ended September 30, 2024, other income, net includes a non-recurring pre-tax gain 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 September 30,				Nine Months Ended September 30,

							(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.  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 acquisition.

 

3)	For both the three and nine months ended September 30, 2025, we repurchased 0.9 million shares of our common stock for $150 million.  As of September 30, 2025, $0.7 billion remained available under our share repurchase authorization.
4)	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	$                                   8.58		$                                   8.66
Restructuring and integration charges (a)	0.30		0.30
Amortization expense (b)	1.02		1.02
Other charges (c)	0.39		0.39
Other gains (d)	(0.36)		(0.36)
Gains and losses on investments (e)	(0.01)		(0.01)
ETB	(0.16)		(0.16)
Adjusted diluted EPS	$                                   9.76		$                                   9.84

							(a)	Represents estimated pre-tax charges of $45 million primarily associated with workforce reductions and integration costs incurred in connection with further restructuring and integrating our business.
