THERMO FISHER SCIENTIFIC INC.

In addition to the financial measures prepared in accordance with generally accepted accounting principles (GAAP), we use certain non-GAAP financial measures such as organic revenue growth, which is reported revenue growth, excluding the impacts of revenues from acquired/divested businesses and the effects of currency translation. We report organic revenue growth because Thermo Fisher management believes that in order to understand the company’s short-term and long-term financial trends, investors may wish to consider the impact of acquisitions/divestitures and foreign currency translation on revenues. Thermo Fisher management uses organic revenue growth to forecast and evaluate the operational performance of the company as well as to compare revenues of current periods to prior periods.

We report adjusted operating income, adjusted operating margin, adjusted other income/(expense), adjusted tax rate, and adjusted EPS. We believe that the use of these non-GAAP financial measures, in addition to GAAP financial measures, helps investors to gain a better understanding of our core operating results and future prospects, consistent with how management measures and forecasts the company’s core operating performance, especially when comparing such results to previous periods, forecasts, and to the performance of our competitors. Such measures are also used by management in their financial and operating decision-making and for compensation purposes. To calculate these measures we exclude, as applicable:

•Certain acquisition-related costs, including charges for the sale of inventories revalued at the date of acquisition, significant transaction/acquisition-related costs, including changes in estimates of contingent acquisition-related consideration, and other costs associated with obtaining short-term financing commitments for pending/recent acquisitions. We exclude these costs because we do not believe they are indicative of our normal operating costs.

•Costs/income associated with restructuring activities and large-scale abandonments of product lines, such as reducing overhead and consolidating facilities. We exclude these costs because we believe that the costs related to restructuring activities and large-scale abandonment of product lines are not indicative of our normal operating costs.

•Equity in earnings/losses of unconsolidated entities; impairments of long-lived assets; and certain other gains and losses that are either isolated or cannot be expected to occur again with any predictability, including gains/losses on investments, the sale of businesses, product lines, and real estate, significant litigation-related matters, curtailments/settlements of pension plans, and the early retirement of debt. We exclude these items because they are outside of our normal operations and/or, in certain cases, are difficult to forecast accurately for future periods.

•The expense associated with the amortization of acquisition-related intangible assets because a significant portion of the purchase price for acquisitions may be allocated to intangible assets that have lives of up to 20 years. Exclusion of the amortization expense allows comparisons of operating results that are consistent over time for both our newly acquired and long-held businesses and with both acquisitive and non-acquisitive peer companies.

•The noncontrolling interest and tax impacts of the above items and the impact of significant tax audits or events (such as changes in deferred taxes from enacted tax rate/law changes), the latter of which we exclude because they are outside of our normal operations and difficult to forecast accurately for future periods.

We report free cash flow, which is operating cash flow less net capital expenditures, to provide a view of the continuing operations’ ability to generate cash for use in acquisitions and other investing and financing activities. The company also uses this measure as an indication of the strength of the company. Free cash flow is not a measure of cash available for discretionary expenditures since we have certain non-discretionary obligations such as debt service that are not deducted from the measure.

The non-GAAP financial measures of the company’s results of operations and cash flows included in this Form 10-Q are not meant to be considered superior to or a substitute for the company’s results of operations prepared in accordance with GAAP. Reconciliations of such non-GAAP financial measures to the most directly comparable GAAP financial measures are set forth within the “Consolidated Results” and “Segment Results” sections and below.

(a)Adjusted results exclude accelerated depreciation on manufacturing assets to be abandoned due to facility consolidations. Adjusted results in the second quarter and first six months of 2025 exclude $5 million and $10 million, respectively, of charges for the sale of inventory revalued at the date of acquisition. Adjusted results in the first six months of 2024 also exclude $13 million of charges for inventory write-downs associated with large-scale abandonment of product lines.

(b)Adjusted results exclude certain third-party expenses, principally transaction/integration costs related to recent acquisitions and charges/credits for changes in estimates of contingent acquisition consideration.

(c)Adjusted results exclude restructuring and other costs consisting principally of severance, impairments of long-lived assets, net charges/credits for pre-acquisition litigation and other matters, and abandoned facility and other expenses of headcount reductions and real estate consolidations.

(d)Adjusted results exclude net gains/losses on investments. Adjusted results in the second quarter and first six months of 2025 also exclude $5 million of charges for settlement of pension plans.

(e)Adjusted results exclude incremental tax impacts for the reconciling items between GAAP and adjusted net income, incremental tax impacts as a result of tax rate/law changes, and the tax impacts from audit settlements.

(f)Adjusted results exclude the incremental impacts for the reconciling items between GAAP and adjusted net income attributable to noncontrolling interests.
