Markets served include pharmaceutical and biotech, academic and government, industrial and applied, as well as healthcare and diagnostics.

Interim Financial Statements

The interim condensed consolidated financial statements presented herein have been prepared by the company, are unaudited and, in the opinion of management, reflect all adjustments of a normal recurring nature necessary for a fair statement of the financial position at June 28, 2025, the results of operations for the three- and six-month periods ended June 28, 2025 and June 29, 2024, and the cash flows for the six-month periods ended June 28, 2025 and June 29, 2024. Interim results are not necessarily indicative of results for a full year.

The condensed consolidated balance sheet presented as of December 31, 2024, has been derived from the audited consolidated financial statements as of that date. The condensed consolidated financial statements and notes are presented as permitted by Form 10-Q and do not contain all information that is included in the annual financial statements and notes thereto of the company. The condensed consolidated financial statements and notes included in this report should be read in conjunction with the 2024 financial statements and notes included in the company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC). Certain reclassifications of prior year amounts have been made to conform to the current year presentation.

Note 1 to the consolidated financial statements for 2024 describes the significant accounting estimates and policies used in preparation of the consolidated financial statements. There have been no material changes in the company’s significant accounting policies during the six months ended June 28, 2025.

Amounts and percentages reported within these condensed consolidated financial statements are presented and calculated based on underlying unrounded amounts. As a result, the sum of components may not equal corresponding totals due to rounding.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

The company’s estimates include, among others, asset reserve requirements as well as the amounts of future cash flows associated with certain assets and businesses that are used in assessing the risk of impairment. Actual results could differ from those estimates.

Recent Accounting Pronouncements

The following table provides a description of recent accounting pronouncements adopted and those standards not yet adopted with potential for a material impact on the company's financial statements or disclosures.

Credit Facilities

The company has a revolving credit facility (the Facility) with a bank group that provides for up to $5.00 billion of unsecured multi-currency revolving credit. The Facility expires on January 7, 2027. The revolving credit agreement calls for interest at either a Term Secured Overnight Financing Rate (SOFR), a Euro Interbank Offered Rate (EURIBOR)-based rate (for funds drawn in euro), or a rate based on the prime lending rate of the agent bank, at the company’s option. The agreement contains affirmative, negative and financial covenants, and events of default customary for facilities of this type. The covenants in the Facility include a Consolidated Net Interest Coverage Ratio (Consolidated EBITDA to Consolidated Net Interest Expense), as such terms are defined in the Facility. Specifically, the company has agreed that, so long as any lender has any commitment under the Facility, any letter of credit is outstanding under the Facility, or any loan or other obligation is outstanding under the Facility, it will maintain a minimum Consolidated Net Interest Coverage Ratio of 3.5:1.0 as of the last day of any fiscal quarter. As of June 28, 2025, no borrowings were outstanding under the Facility, although available capacity was reduced by immaterial outstanding letters of credit.

Commercial Paper Programs

The company has commercial paper programs pursuant to which it may issue and sell unsecured, short-term promissory notes (CP Notes). Under the U.S. program, a) maturities may not exceed 397 days from the date of issue and b) the CP Notes are issued on a private placement basis under customary terms in the commercial paper market and are not redeemable prior to maturity nor subject to voluntary prepayment. Under the euro program, maturities may not exceed 183 days and may be denominated in euro, U.S. dollars, Japanese yen, British pounds sterling, Swiss franc, Canadian dollars or other currencies. Under both programs, the CP Notes are issued at a discount from par (or premium to par, in the case of negative interest rates), or, alternatively, are sold at par and bear varying interest rates on a fixed or floating basis.

Senior Notes

Interest is payable annually on the euro and public Swiss franc-denominated fixed rate senior notes and semi-annually on all other senior notes. Each of the U.S. dollar and euro-denominated fixed rate senior notes, and Japanese yen-denominated and Swiss franc-denominated private placement notes may be redeemed at a redemption price of 100% of the principal amount plus a specified make-whole premium and accrued interest, together with swap breakage costs payable to holders of the Japanese yen-denominated and Swiss franc-denominated private placement notes who have entered into cross-currency swap agreements. The company is subject to certain affirmative and negative covenants under the indentures and note purchase agreement governing the senior notes, the most restrictive of which limits the ability of the company to pledge certain property and assets as security under borrowing arrangements. The company was in compliance with all covenants related to its senior notes at June 28, 2025.

Thermo Fisher Scientific (Finance I) B.V. (Thermo Fisher International), a wholly-owned finance subsidiary of the company, issued each of the following notes outstanding as of June 28, 2025, included in the table above (collectively, the “Euronotes”) in registered public offerings: the 0.00% Senior Notes due 2025, the 0.80% Senior Notes due 2030, the 1.125% Senior Notes due 2033, the 1.625% Senior Notes due 2041, and the 2.00% Senior Notes due 2051. The company has fully and unconditionally guaranteed all of Thermo Fisher International’s obligations under the Euronotes and all of Thermo Fisher International’s other debt securities, and no other subsidiary of the company will guarantee these obligations. Thermo Fisher International is a “finance subsidiary” as defined in Rule 13-01(a)(4)(vi) of the Exchange Act, with no assets or operations other than those related to the issuance, administration and repayment of the Euronotes and other debt securities issued by Thermo Fisher International from time to time. The financial condition, results of operations and cash flows of Thermo Fisher International are consolidated in the financial statements of the company.

Note 5.    Commitments and Contingencies

Environmental Matters

The company is currently involved in various stages of investigation and remediation related to environmental matters. The company cannot predict all potential costs related to environmental remediation matters and the possible impact on future operations given the uncertainties regarding the extent of the required cleanup, the complexity and interpretation of applicable laws and regulations, the varying costs of alternative cleanup methods and the extent of the company’s responsibility. Expenses for environmental remediation matters related to the costs of installing, operating and maintaining groundwater-treatment systems and other remedial activities related to historical environmental contamination at the company’s domestic and international facilities were not material in any period presented. At June 28, 2025, there have been no material changes to the accruals for pending environmental-related matters disclosed in the company’s 2024 financial statements and notes included in the company’s Annual Report on Form 10-K. While management believes the accruals for environmental remediation are adequate based on current estimates of remediation costs, the company may be subject to additional remedial or compliance costs due to future events such as changes in existing laws and regulations, changes in agency direction or enforcement policies, developments in remediation technologies or changes in the conduct of the company’s operations, which could have a material adverse effect on the company’s financial position, results of operations and cash flows.

Litigation and Related Contingencies

The company is involved in various disputes, governmental and/or regulatory inspections, inquiries, investigations and proceedings, and litigation matters that arise from time to time in the ordinary course of business. The disputes and litigation matters include product liability, intellectual property, employment and commercial issues. Due to the inherent uncertainties associated with pending litigation or claims, the company cannot predict the outcome, nor, with respect to certain pending litigation or claims where no liability has been accrued, make a meaningful estimate of the reasonably possible loss or range of loss that could result from an unfavorable outcome. The company has no material accruals for pending litigation or claims for which accrual amounts are not disclosed in the company’s 2024 financial statements and notes included in the company’s Annual Report on Form 10-K, nor are material losses deemed probable for such matters. It is reasonably possible, however, that an unfavorable outcome that exceeds the company’s current accrual estimate, if any, for one or more such matters could have a material adverse effect on the company’s results of operations, financial position and cash flows.

Product Liability, Workers Compensation and Other Personal Injury Matters

The company is involved in various proceedings and litigation that arise from time to time in connection with product liability, workers compensation and other personal injury matters. At June 28, 2025, there have been no material changes to the accruals for pending product liability, workers compensation, and other personal injury matters disclosed in the company’s 2024 financial statements and notes included in the company’s Annual Report on Form 10-K. Although the company believes that the amounts accrued and estimated insurance recoveries are probable and appropriate based on available information, including actuarial studies of loss estimates, the process of estimating losses and insurance recoveries involves a considerable degree of judgment by management and the ultimate amounts could vary, which could have a material adverse effect on the company’s results of operations, financial position, and cash flows. Insurance contracts do not relieve the company of its primary obligation with respect to any losses incurred. The collectability of amounts due from its insurers is subject to the solvency and willingness of the insurer to pay, as well as the legal sufficiency of the insurance claims. Management monitors the payment history as well as the financial condition and ratings of its insurers on an ongoing basis.

Restructuring and Other Costs

In the first six months of 2025, restructuring and other costs primarily included continuing charges for headcount reductions and facility consolidations in an effort to streamline operations, impairment of long-lived assets, and, to a lesser extent, net charges for pre-acquisition litigation and other matters. In 2025, severance actions associated with facility consolidations and cost reduction measures affected approximately 2% of the company’s workforce.

As of August 1, 2025, the company has identified restructuring actions, primarily in the Laboratory Products and Biopharma Services segment, that it expects will result in additional charges of approximately $140 million, primarily in 2025, and expects to identify additional actions in future periods.

Restructuring and other costs by segment are as follows:

Note 7.    Income Taxes

The provision for income taxes in the accompanying statements of income differs from the provision calculated by applying the statutory federal income tax rate to income before provision for income taxes due to the following:

	Six months ended
(In millions)	June 28, 2025			June 29, 2024

Provision for/(benefit from) income taxes	$	187		$	408

During the first quarter of 2025, the company recorded a deferred tax benefit of $125 million resulting from the recognition of a tax attribute related to a domestication transaction. During the second quarter of 2025, the company recorded a deferred tax benefit of $153 million related to capital losses generated as part of intra-entity transactions and a $93 million benefit in jurisdictions where the deferred tax assets are now expected to be realized due to forecasted income.

During the first quarter of 2024, the company recorded a tax reserve and associated interest of $240 million related to the potential settlement of international tax audits for tax years 2009 through 2016, which were settled during 2024. During the second quarter of 2024, the company recorded a benefit of $183 million, primarily in jurisdictions where the deferred tax assets are now expected to be realized due to forecasted income.

The company has operations and a taxable presence in approximately 70 countries outside the U.S. The company's effective income tax rate differs from the U.S. federal statutory rate each year due to certain operations that are subject to tax incentives, state and local taxes, and foreign taxes that are different than the U.S. federal statutory rate.

On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was enacted. The OBBBA includes a broad range of provisions, such as the permanent extension of certain otherwise expiring provisions, modifications to the international tax framework and the reinstatement of favorable tax treatment for certain business provisions. While most of the changes made by the OBBBA are effective in future tax years, some of its provisions are effective in 2025. We are currently evaluating its impact on our consolidated financial statements.

Unrecognized Tax Benefits

As of June 28, 2025, the company had $0.52 billion of unrecognized tax benefits substantially all of which, if recognized, would reduce the effective tax rate. A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows:

(In millions)	2025

Note 12.    Acquisitions

The company’s acquisitions have historically been made at prices above the determined fair value of the acquired identifiable net assets, resulting in goodwill, primarily due to expectations of the synergies that will be realized by combining the businesses and the benefits that will be gained from the assembled workforces. These synergies include the elimination of redundant facilities, functions and staffing; use of the company’s existing commercial infrastructure to expand sales of the acquired businesses’ products and services; and use of the commercial infrastructure of the acquired businesses to cost-effectively expand sales of company products and services.

Acquisitions have been accounted for using the acquisition method of accounting, and the acquired companies’ results have been included in the accompanying financial statements from their respective dates of acquisition.

Pending Acquisition

The company has entered into an agreement with Solventum Corporation to acquire its Purification and Filtration business. It subsequently amended the agreement to exclude Solventum’s drinking water filtration business from the scope of the business to be acquired and revised the cash consideration payable at closing to approximately $4.0 billion. Solventum’s Purification and Filtration business is a leading provider of purification and filtration technologies used in the production of biologics as well as in medical technologies and industrial applications. The transaction, which is expected to be completed by the end of 2025, is subject to customary closing conditions. Upon completion, Solventum’s Purification and Filtration business will become part of the Life Sciences Solutions segment.

2024

On July 10, 2024, the company acquired, within the Life Sciences Solutions segment, Olink Holding AB (publ), a Swedish-based provider of next-generation proteomics solutions. The acquisition enhances the segment’s capabilities in the high-growth proteomics market with the addition of highly differentiated solutions. It also complements the existing life sciences and mass spectrometry offerings, accelerating protein biomarker discovery and providing strong synergy opportunities. The goodwill recorded as a result of this business combination is not tax deductible.

The components of the purchase price and net assets acquired are as follows:

(In millions)	Olink
Purchase price
Cash paid	$	3,215
Purchase price payable	28
Cash acquired	(97)
	$	3,146
Net assets acquired
Definite-lived intangible assets

Product technology	207
Tradenames	97
Goodwill	2,301
Net tangible assets	9
Deferred tax assets (liabilities)	(176)
	$	3,146

The weighted-average amortization periods for definite-lived intangible assets acquired in 2024 are 19 years for customer relationships, 15 years for product technology, and 15 years for tradenames. The weighted-average amortization period for definite-lived intangible assets acquired in 2024 is 18 years.

Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

Forward-looking statements, within the meaning of Section 21E of the Securities Exchange Act of 1934 (the Exchange Act), are made throughout this Management’s Discussion and Analysis of Financial Condition and Results of Operations. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements, including without limitation statements regarding: projections of revenues, expenses, earnings, margins, tax rates, tax provisions, cash flows, pension and benefit obligations and funding requirements, and our liquidity position; cost reductions, restructuring activities, new product and service developments, competitive strengths or market position, acquisitions or divestitures; growth, declines and other trends in markets we sell into; new or modified laws, regulations and accounting pronouncements; outstanding claims, legal proceedings, tax audits and assessments and other contingent liabilities; foreign currency exchange rates and fluctuations in those rates; general economic and capital markets conditions; the timing of any of the foregoing; assumptions underlying any of the foregoing; and any other statements that address events or developments that Thermo Fisher intends or believes will or may occur in the future. Without limiting the foregoing, the words “believes,” “anticipates,” “plans,” “expects,” “seeks,” “estimates,” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements are accompanied by such words. While the company may elect to update forward-looking statements in the future, it specifically disclaims any obligation to do so, even if the company’s estimates change, and readers should not rely on those forward-looking statements as representing the company’s views as of any date subsequent to the date of the filing of this report.

A number of important factors could cause the results of the company to differ materially from those indicated by such forward-looking statements, including those detailed under the caption “Risk Factors” in the company’s Annual Report on Form 10-K for the year ended December 31, 2024 (which is on file with the SEC). Important factors that could cause actual results to differ materially from those indicated by forward-looking statements include risks and uncertainties relating to: the need to develop new products and adapt to significant technological change; implementation of strategies for improving growth; general economic conditions and related uncertainties; dependence on customers’ capital spending policies and government funding policies; the effect of economic and political conditions, impact of tariffs, and exchange rate fluctuations on international operations; use and protection of intellectual property; the effect of changes in governmental regulations; any natural disaster, public health crisis, pandemic, or other catastrophic event; and the effect of laws and regulations governing government contracts, as well as the possibility that expected benefits related to recent or pending acquisitions may not materialize as expected.

The company refers to various amounts or measures not prepared in accordance with generally accepted accounting principles (non-GAAP measures). These non-GAAP measures are further described and reconciled to their most directly comparable amount or measure under the section “Non-GAAP Measures” later in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Certain amounts and percentages reported within this Quarterly Report on Form 10-Q are presented and calculated based on underlying unrounded amounts. As a result, the sum of components may not equal corresponding totals due to rounding.

Organic Revenue Growth

Organic revenue growth (non-GAAP measure)	2	%	1	%

During the second quarter of 2025, revenues grew in the pharma and biotech market due to increased demand from customers. Revenues in the academic and government and industrial and applied markets declined, reflecting some customer hesitancy in a more uncertain environment, which resulted in muted demand for equipment and instruments. Revenue to customers in the diagnostics and healthcare market declined as we navigated headwinds in China. During the second quarter of 2025, sales grew in North America and Europe. Sales declined in Asia-Pacific, including China. Contributions to organic revenue during the second quarter of 2025 from the Laboratory Products and Biopharma Services and Life Sciences Solutions segments were partially offset by declines in the Analytical Instruments segment.

During the first six months of 2025, revenues grew in the pharma and biotech market due to increased demand from customers, partially offset by reduced demand for COVID-19 vaccine and therapy related products and services. Revenues in the academic and government market declined driven by the macro conditions in the U.S. and China. Revenue to customers in the industrial and applied market grew slightly. Revenue to customers in the diagnostics and healthcare market was flat. During the first six months of 2025, sales grew in North America and Europe. Sales were flat in Asia-Pacific, but declined in China. The first six months of 2025 were also impacted by two fewer selling days than the first six months of 2024. Contributions to organic revenue during the first six months of 2025 from the Laboratory Products and Biopharma Services, Life Sciences Solutions, and Specialty Diagnostics segments were partially offset by declines in the Analytical Instruments segment.

The company continues to execute its proven growth strategy which consists of three pillars:

GAAP operating income margin and adjusted operating income margin decreased in the second quarter of 2025 due primarily to unfavorable business mix, the impacts of tariffs and related foreign exchange, and strategic investments, partially offset by very strong productivity improvements. GAAP operating income margin in the second quarter of 2025 benefited from lower amortization expense when compared to 2024; however, we recognized net credits for changes in contingent consideration in 2024, which did not recur in 2025.

GAAP operating income margin and adjusted operating income margin decreased during the first six months of 2025 due primarily to unfavorable business mix, the impacts of strategic investments, partially offset by strong productivity improvements. GAAP operating income margin in the first six months of 2025 benefited from lower levels of amortization expense when compared to 2024.

The company’s references to strategic investments generally refer to targeted spending for enhancing commercial capabilities, including expansion of geographic sales reach and e-commerce platforms, marketing initiatives, expanded service and operational infrastructure, research and development projects and other expenditures to enhance the customer experience, as well as incentive compensation and recognition for employees. The company’s references throughout this discussion to productivity improvements generally refer to improved cost efficiencies from its Practical Process Improvement (PPI) business system to address inflation, including reduced costs resulting from implementing continuous improvement methodologies, global sourcing initiatives, a lower cost structure following restructuring actions including headcount reductions and consolidation of facilities, and low cost region manufacturing.

On a reported basis, the bioproduction business grew $194 million, driven by higher demand from pharma and biotech customers, and genetic sciences grew $56 million, driven by the 2024 acquisition of Olink. Biosciences revenue declined $50 million, due to lower demand from academic and government customers. The decrease in segment income margin resulted primarily from unfavorable business mix, the impact of the Olink acquisition, partially offset by very strong productivity improvements.

The decrease in organic revenues in the second quarter of 2025 was driven by the impact of tariffs and the policy focus of the U.S. administration, which is leading to more muted demand for equipment and instrumentation. On a reported basis, the electron microscopy and chemical analysis businesses each declined $32 million, driven by decreased demand for instrumentation from U.S.-based academic and government customers, as well as customers in China. The decrease in segment income margin was driven by the impacts of tariffs and related foreign exchange. Additionally, strong productivity was more than offset by lower volumes and strategic investments.

Net interest expense (interest expense less interest income) in the second quarter and first six months of 2025 increased due primarily to lower cash, and cash equivalents and short-term investments balances, as well as lower interest rates on these balances when compared to the second quarter and first six months of 2024. In the second quarter and first six months of 2025, the company’s net interest expense was reduced by approximately $66 million and $133 million, respectively, as a result of its interest rate swap and cross-currency interest rate swap arrangements. In the second quarter and first six months of 2024, the company’s net interest expense was reduced by approximately $67 million and $132 million, respectively, as a result of its interest rate swap and cross-currency interest rate swap arrangements (Note 10).

GAAP other income/(expense) and adjusted other income/(expense) includes currency transaction gains/losses on non-operating monetary assets and liabilities, and net periodic pension benefit cost/income, excluding the service cost component. GAAP other income/(expense) in the first six months of 2025 and 2024 also includes $2 million and $10 million, respectively, of net gains on investments. GAAP other income/(expense) in the second quarter of 2025 also includes $5 million of charges for settlement of pension plans.

The company’s GAAP and adjusted tax rates decreased in the first six months of 2025 compared to 2024, due to a $125 million deferred tax benefit resulting from the recognition of a tax attribute related to a domestication transaction in the first quarter of 2025. The company’s GAAP and adjusted rates in the second quarter of 2025 were also impacted by a deferred tax benefit of $153 million related to capital losses generated as part of intra-entity transactions and a $93 million benefit in jurisdictions where the deferred tax assets are now expected to be realized due to forecasted income. The company’s GAAP and adjusted tax rates in the first six months of 2024 were impacted by a benefit of $183 million, primarily in jurisdictions where the deferred tax assets are now expected to be realized due to forecasted income and a benefit of $102 million resulting from capital losses generated as part of intra-entity transactions. The company’s GAAP tax rate in the first six months of 2024 was also impacted by $176 million of expense, net, for a provision associated with a tax audit (Note 7).

The effective tax rates in both 2025 and 2024 were also affected by relatively significant earnings in lower tax jurisdictions. Due primarily to the non-deductibility of intangible asset amortization for tax purposes, the company’s cash payments for income taxes are higher than its income tax expense for financial reporting purposes and are expected to total approximately $1.80 billion in 2025.

The company expects its GAAP effective tax rate in 2025 will be between 6% and 8% based on currently forecasted rates of profitability in the countries in which the company conducts business and expected generation of foreign tax credits. The effective tax rate can vary significantly from period to period as a result of discrete income tax factors and events. The company expects its adjusted tax rate will be approximately 10.5% in 2025.

THERMO FISHER SCIENTIFIC INC.

The company has operations and a taxable presence in approximately 70 countries outside the U.S. Some of these countries have lower tax rates than the U.S. The company’s ability to obtain a benefit from lower tax rates outside the U.S. is dependent on its relative levels of income in countries outside the U.S. and on the statutory tax rates in those countries. Based on the dispersion of the company’s non-U.S. income tax provision among many countries, the company believes that a change in the statutory tax rate in any individual country is not likely to materially affect the company’s income tax provision or net income.

Equity in earnings/losses of unconsolidated entities was impacted by an $88 million impairment of an equity method investment in the second quarter of 2024.

Weighted average diluted shares decreased in 2025 compared to 2024, primarily due to share repurchases.

Liquidity and Capital Resources

The company’s proven growth strategy has enabled it to generate free cash flow as well as access the capital markets. The company deploys its capital primarily via mergers and acquisitions and secondarily via share buybacks and dividends.

(In millions)	June 28, 2025		December 31, 2024
Cash and cash equivalents	$	4,576	$	4,009
Short-term investments	1,814		1,561
Total debt	35,229		31,275

Approximately half of the company’s cash balances and cash flows from operations are from outside the U.S. The company uses its non-U.S. cash for needs outside of the U.S. including acquisitions, capacity expansion, and repayment of third-party foreign debt by foreign subsidiaries. In addition, the company also transfers cash to the U.S. using non-taxable intercompany transactions, including loans and returns of capital, as well as dividends where the related U.S. dividend received deduction or foreign tax credit equals any tax cost arising from the dividends. As a result of using such means of transferring cash to the U.S., the company does not expect any material adverse liquidity effects from its significant non-U.S. cash balances for the foreseeable future.

The company believes that its existing cash and cash equivalents and its future cash flow from operations together with available borrowing capacity under its revolving credit agreement will be sufficient to meet the cash requirements of its existing businesses for the foreseeable future, including at least the next 24 months.

As of June 28, 2025, the company’s short-term obligations and current maturities of long-term obligations totaled $2.21 billion. The company has a revolving credit facility with a bank group that provides up to $5.00 billion of unsecured multi-currency revolving credit (Note 3). If the company borrows under this facility, it intends to leave undrawn an amount equivalent to outstanding commercial paper to provide a source of funds in the event that commercial paper markets are not available. As of June 28, 2025, no borrowings were outstanding under the company’s revolving credit facility, although available capacity was reduced by immaterial outstanding letters of credit.

Operating Activities

During the first six months of 2025, cash provided by income was offset in part by investments in working capital. Changes in other assets and liabilities used cash of $1.43 billion primarily due to the timing of payments for compensation and income taxes. Cash payments for income taxes were $1.20 billion during the first six months of 2025.

During the first six months of 2024, cash provided by income was offset in part by investments in working capital. Changes in other assets and other liabilities used cash of $0.57 billion primarily due to the timing of payments for compensation and income taxes. Cash payments for income taxes were $1.13 billion during the first six months of 2024.

Investing Activities

During the first six months of 2025 the company’s investing activities included purchases of $0.66 billion for the purchase of property, plant and equipment for capacity and capability investments.

THERMO FISHER SCIENTIFIC INC.

During the first six months of 2024, purchases of short-term investments used cash of $1.78 billion. The company’s investing activities also included purchases of $0.65 billion of property, plant and equipment for capacity and capability investments.

The company expects that for all of 2025, expenditures for property, plant and equipment, net of disposals, will be between $1.4 billion and $1.7 billion.

Financing Activities

During the first six months of 2025, issuance of debt provided $2.84 billion of cash. Repayment of debt used cash of $1.63 billion. The company’s financing activities also included the repurchase of $2.00 billion of the company’s common stock (3.6 million shares) and the payment of $0.31 billion in cash dividends. On November 15, 2024, the Board of Directors announced that it replaced the existing authorization to repurchase the company’s common stock, of which $1.00 billion was remaining, with a new authorization to repurchase up to $4.00 billion of the company’s common stock. All of the shares of common stock repurchased by the company during the first quarter of 2025 were under this program. At August 1, 2025, authorization remained for $1.00 billion of future repurchases of the company’s common stock.

During the first six months of 2024, issuance of debt provided $1.20 billion of cash. The company’s financing activities also included the repurchase of $3.00 billion of the company’s common stock (5.5 million shares) and the payment of $0.28 billion in cash dividends.

The company’s commitments for purchases of property, plant and equipment, contractual obligations and other commercial commitments, did not change materially subsequent to December 31, 2024, except for the agreement to acquire Solventum Corporation’s Purification & Filtration business (Note 12).

Non-GAAP Measures

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.

THERMO FISHER SCIENTIFIC INC.

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.

Item 4.    Controls and Procedures

Management’s Evaluation of Disclosure Controls and Procedures

The company’s management, with the participation of the company’s chief executive officer and chief financial officer, has evaluated the effectiveness of the company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on such evaluation, the company’s chief executive officer and chief financial officer concluded that, as of the end of such period, the company’s disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There have been no changes in the company’s internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the fiscal quarter ended June 28, 2025, that have materially affected or are reasonably likely to materially affect the company’s internal control over financial reporting.
