Note 1.    Nature of Operations and Summary of Significant Accounting Policies

Nature of Operations

Thermo Fisher Scientific Inc. (the company or Thermo Fisher) enables customers to make the world healthier, cleaner and safer by helping them accelerate life sciences research, solve complex analytical challenges, increase laboratory productivity, and improve patient health through diagnostics and the development and manufacture of life-changing therapies. 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 29, 2024, the results of operations for the three- and six-month periods ended June 29, 2024 and July 1, 2023, and the cash flows for the six-month periods ended June 29, 2024 and July 1, 2023. Interim results are not necessarily indicative of results for a full year.

The condensed consolidated balance sheet presented as of December 31, 2023 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 2023 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 2023 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 29, 2024.

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.

Inventories

The components of inventories are as follows:

(In millions)	June 29, 2024		December 31, 2023
Raw materials	$	1,974	$	2,057
Work in process	825		705
Finished goods	2,399		2,326
Inventories	$	5,198	$	5,088

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.

Note 2.    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.

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 expected to be tax deductible.

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

(In billions)	Olink
Purchase price
Cash paid	$	3.19
Fair value of noncontrolling interest	0.06
Cash acquired	(0.04)
	$	3.21
Net assets acquired
Definite-lived intangible assets	$	0.99
Goodwill	2.28
Net tangible assets	0.13
Deferred tax assets (liabilities)	(0.19)
	$	3.21

The weighted-average amortization period for definite-lived intangible assets is 18 years.

The preliminary allocation of the purchase price for the acquisition of Olink is based on the estimates of the fair value of the net assets acquired and is subject to adjustment upon finalization, largely with respect to acquired intangible assets and the related deferred taxes. Measurements of these items inherently require significant estimates and assumptions.

2023

On January 3, 2023, the company acquired, within the Specialty Diagnostics segment, The Binding Site Group, a U.K.-based provider of specialty diagnostic assays and instruments to improve the diagnosis and management of blood cancers and immune system disorders. The acquisition expands the segment’s portfolio with the addition of pioneering innovation in diagnostics and monitoring for multiple myeloma. The goodwill recorded as a result of this business combination is not tax deductible.

On August 14, 2023, the company acquired, within the Laboratory Products and Biopharma Services segment, CorEvitas, LLC, a U.S.-based provider of regulatory-grade, real-world evidence for approved medical treatments and therapies. The acquisition expands the segment’s portfolio with the addition of highly complementary real-world evidence solutions to enhance decision-making as well as the time and cost of drug development. 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)	The Binding Site		CorEvitas

	$	2,699	$	910

In addition, in 2023, the company acquired, within the Analytical Instruments segment, a U.S.-based developer of Raman-based spectroscopy solutions for in-line measurement.

The weighted-average amortization periods for definite-lived intangible assets acquired in 2023 are 18 years for customer relationships, 14 years for product technology, 15 years for tradenames, and 13 years for backlog. The weighted average amortization period for all definite-lived intangible assets acquired in 2023 is 17 years.

Note 5.    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:

State income taxes, net of federal tax	39			53
Equity method investments	(45)			(6)
Other, net	(4)			(21)
Provision for income taxes	$	408		$	98

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. 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.

Unrecognized Tax Benefits

As of June 29, 2024 the company had $0.70 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)	2024
Balance at beginning of year	$	540
Additions for tax positions of current year	9
Additions for tax positions of prior years	199
Reductions for tax positions of prior years	(46)
Balance at end of period	$	702

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 29, 2024, 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 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 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 Japanese yen-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 29, 2024.

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 29, 2024, 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 8.    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 29, 2024, there have been no material changes to the accruals for pending environmental-related matters disclosed in the company’s 2023 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 2023 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

(Unaudited)

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 29, 2024, 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 2023 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.

Contingent consideration	87		—		—		87
Total liabilities	$	377	$	—	$	290	$	87

The company determines the fair value of its insurance contracts by obtaining the cash surrender value of the contracts from the issuer. The fair value of derivative contracts is the estimated amount that the company would receive/pay upon liquidation of the contracts, taking into account the change in interest rates and currency exchange rates. The company initially measures the fair value of acquisition-related contingent consideration based on amounts expected to be transferred (probability-weighted) discounted to present value. Changes to the fair values of contingent consideration are recorded in selling, general and administrative expense.

In the six-month periods ended June 29, 2024 and July 1, 2023 the company recorded $10 million and $(44) million, respectively, of net gains/(losses) on investments, which are included in other income/(expense) in the accompanying statements of income.

The following table provides a rollforward of the fair value, as determined by level 3 inputs (such as likelihood of achieving production or revenue milestones, as well as changes in the fair values of the investments underlying a recapitalization investment portfolio), of the contingent consideration.

Gains and losses recognized on currency exchange contracts are included in the accompanying statements of income together with the corresponding, offsetting losses and gains on the underlying hedged transactions.

The company uses foreign currency-denominated debt, certain foreign currency-denominated payables, and cross-currency interest rate swaps to partially hedge its net investments in foreign operations against adverse movements in exchange rates. A portion of the company’s euro-denominated senior notes, certain foreign currency-denominated payables, and its cross-currency interest rate swaps have been designated as, and are effective as, economic hedges of part of the net investment in a foreign operation. Accordingly, foreign currency transaction gains or losses due to spot rate fluctuations on the euro-denominated debt instruments and certain foreign currency-denominated payables, and contract fair value changes on the cross-currency interest rate swaps, excluding interest accruals, are included in currency translation adjustment within other comprehensive items and shareholders’ equity.

See Note 1 to the consolidated financial statements for 2023 included in the company’s Annual Report on Form 10-K for additional information on the company’s risk management objectives and strategies.

Fair Value of Other Financial Instruments

The carrying value and fair value of the company’s debt instruments are as follows:

Other	74		74		77		77
	$	35,197	$	32,057	$	34,727	$	32,268

The fair value of debt instruments, excluding private placement notes, was determined based on quoted market prices and on borrowing rates available to the company at the respective period ends, which represent level 2 measurements. The fair value of private placement notes was determined based on internally developed pricing models and unobservable inputs, which represent level 3 measurements.

Note 12.    Restructuring and Other Costs

In the first six months of 2024, 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 2024, severance actions associated with facility consolidations and cost reduction measures affected approximately 1% of the company’s workforce.

As of August 2, 2024, the company has identified restructuring actions that will result in additional charges of approximately $80 million, primarily in 2024, and expects to identify additional actions in future periods which will be recorded when specified criteria are met, such as communication of benefit arrangements or when the costs have been incurred.

Restructuring and other costs by segment are as follows:

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; the COVID-19 pandemic; 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, 2023 (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 COVID-19 pandemic; 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 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 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.

Since 2020, the Life Sciences Solutions and Specialty Diagnostics segments as well as the laboratory products business have supported COVID-19 diagnostic testing. Additionally, our pharma services business has provided our pharma and biotech customers with the services they needed to develop and produce vaccines and therapies globally. Since the company’s acquisition of PPD in December 2021, the clinical research business has continued to play a leading role in supporting the clinical trials for COVID-19 vaccines and therapies. These positive impacts are expected to continue at much lower levels in 2024 as customer testing as well as therapy and vaccine demand declines. Sales of products related to COVID-19 testing were $0.02 billion and $0.08 billion in the second quarter of 2024 and 2023, respectively, and $0.05 billion and $0.22 billion in the first six months of 2024 and 2023, respectively.

During the second quarter of 2024, revenues from pharma and biotech customers declined due to reduced demand for our products and services that support COVID-19 vaccines and therapies as well as a more muted macroeconomic environment, partially offset through strong commercial execution. Revenues in the academic and government as well as the industrial and applied markets grew due to demand for analytical instruments. The diagnostics and healthcare market declined due to decreased demand for COVID-19 testing products. During the second quarter of 2024, sales growth was strong in Asia-Pacific, including China. Sales in Europe grew slightly and in North America declined due to decreased demand for COVID-19 related products, as well as a challenging macroeconomic environment. Contributions to organic revenue during the second quarter of 2024 from the Analytical Instruments and Specialty Diagnostics segments were more than offset by declines in the Laboratory Products and Biopharma Services and Life Sciences Solutions segments.

During the first six months of 2024, all of our end markets were negatively impacted by a more muted macroeconomic environment and moderate economic activity in China. Revenues from pharma and biotech and diagnostics and healthcare customers declined due to demand for COVID-19 related products and services. Revenues in the academic and government as well as the industrial and applied markets were flat. During the first six months of 2024, sales grew slightly in Asia-Pacific, including China. Sales growth in Europe was flat and sales in North America declined due to decreased demand for COVID-19 related products. Contributions to organic revenue during the first six months of 2024 from the Specialty Diagnostics and Analytical Instruments segments were more than offset by declines in the Life Sciences Solutions and Laboratory Products and Biopharma Services segments.

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

•High-impact innovation,

•Our trusted partner status with customers, and

•Our unparalleled commercial engine.

GAAP operating income margin and adjusted operating income margin increased in the second quarter of 2024 due primarily to strong productivity improvements, partially offset by unfavorable business mix. GAAP operating income margin in the second quarter of 2024 was also impacted by net credits for changes in estimates of contingent acquisition consideration, lower levels of restructuring and other charges incurred for headcount reductions and facility consolidations in an effort to streamline operations (Note 12), and, to a lesser extent, lower amortization expense.

GAAP operating income margin and adjusted operating income margin increased in the first six months of 2024 due primarily to strong productivity improvements, partially offset by unfavorable business mix. GAAP operating income margin during the first six months of 2024 was also impacted by lower levels of restructuring and other charges incurred for headcount reductions and facility consolidations in an effort to streamline operations (Note 12).

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.

Notable Recent Acquisitions

On January 3, 2023, the company acquired, within the Specialty Diagnostics segment, The Binding Site Group, a U.K.-based provider of specialty diagnostic assays and instruments to improve the diagnosis and management of blood cancers and immune system disorders.

The increase in organic revenues in the second quarter of 2024 was primarily driven by underlying growth in the transplant diagnostics and immunodiagnostics businesses, as well as in the healthcare market channel, largely offset by decreased demand for products addressing diagnosis of COVID-19. Segment income margin was flat in the second quarter of 2024 when compared to 2023 due to good productively improvements, offset by strategic investments.

Net interest expense (interest expense less interest income) in the second quarter and first six months of 2024 decreased due primarily to higher cash, and cash equivalents and short-term investments balances, as well as higher interest rates on these balances when compared to the second quarter and first six months of 2023. The company’s net interest expense was reduced by approximately $67 million and $132 million in the second quarter and first six months of 2024, 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 2023, the company’s net interest expense was reduced by approximately $16 million and $33 million, respectively, as a result of these 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 2024 and 2023 also includes $10 million and $(43) million, respectively, of net gains/(losses) on investments.

The company’s GAAP tax rate increased in the first six months of 2024 compared to 2023 primarily due to $176 million of expense, net, for a provision associated with a tax audit recorded in the first quarter of 2024. The company’s GAAP and adjusted tax rates in the first six months of 2024 were also 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. The company’s GAAP and adjusted tax rates in the first six months of 2023 were impacted by a tax benefit of $91 million, net of related tax expenses, from a foreign exchange loss on an intercompany debt refinancing transaction in the second quarter of 2023. The company’s GAAP and adjusted tax rates in the six-month periods ended June 29, 2024 and July 1, 2023 were also impacted by $102 million and $144 million, respectively, of tax benefits resulting from capital losses generated as part of intra-entity transactions (Note 5).

THERMO FISHER SCIENTIFIC INC.

The effective tax rates in both 2024 and 2023 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 $1.65 billion in 2024.

The company expects its GAAP effective tax rate in 2024 will be between 9% and 11%. 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 2024.

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, aside from any resulting one-time adjustment to the company’s deferred tax balances to reflect a new rate.

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 2024 compared to 2023 due to share repurchases, net of option dilution.

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.

Cash and cash equivalents	$	7,073	$	8,077
Short-term investments	1,750		3
Total debt	35,404		34,917

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 29, 2024, the company’s short-term obligations and current maturities of long-term obligations totaled $5.12 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 7). 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 29, 2024, 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 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.

THERMO FISHER SCIENTIFIC INC.

During the first six months of 2023, cash provided by income was offset in part by investments in working capital. Changes in other assets and other liabilities used cash of $1.50 billion primarily due to the timing of payments for compensation and income taxes. A decrease in accounts payable used cash of $0.87 billion. Cash payments for income taxes were $0.78 billion during the first six months of 2023.

Investing Activities

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.

During the first six months of 2023, acquisitions used cash of $2.75 billion. The company’s investing activities also included purchases of $0.74 billion of property, plant and equipment for capacity and capability investments.

The company expects that for all of 2024, expenditures for property, plant and equipment, net of disposals, will be between $1.3 billion and $1.5 billion.

Financing Activities

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. On November 14, 2023, 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 2024 were under this program. At August 2, 2024, authorization remained for $1.00 billion of future repurchases of the company’s common stock.

During the first six months of 2023, repayment of senior notes used cash of $1.00 billion. The company’s financing activities also included the repurchase of $3.00 billion of the company’s common stock (5.2 million shares) and the payment of $0.25 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, 2023, except in connection with the completion of the Olink acquisition, which occurred on July 10, 2024 (Note 2).

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.

29

THERMO FISHER SCIENTIFIC INC.

•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 excluding 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.

Acquisitions

6 Months Ended

Jun. 29, 2024

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]

Acquisitions

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.

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 expected to be tax deductible.

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

(In billions)	Olink
Purchase price
Cash paid	$	3.19
Fair value of noncontrolling interest	0.06
Cash acquired	(0.04)
	$	3.21
Net assets acquired
Definite-lived intangible assets	$	0.99
Goodwill	2.28
Net tangible assets	0.13
Deferred tax assets (liabilities)	(0.19)
	$	3.21

The weighted-average amortization period for definite-lived intangible assets is 18 years.

The preliminary allocation of the purchase price for the acquisition of Olink is based on the estimates of the fair value of the net assets acquired and is subject to adjustment upon finalization, largely with respect to acquired intangible assets and the related deferred taxes. Measurements of these items inherently require significant estimates and assumptions.

2023

On January 3, 2023, the company acquired, within the Specialty Diagnostics segment, The Binding Site Group, a U.K.-based provider of specialty diagnostic assays and instruments to improve the diagnosis and management of blood cancers and immune system disorders. The acquisition expands the segment’s portfolio with the addition of pioneering innovation in diagnostics and monitoring for multiple myeloma. The goodwill recorded as a result of this business combination is not tax deductible.

On August 14, 2023, the company acquired, within the Laboratory Products and Biopharma Services segment, CorEvitas, LLC, a U.S.-based provider of regulatory-grade, real-world evidence for approved medical treatments and therapies. The acquisition expands the segment’s portfolio with the addition of highly complementary real-world evidence solutions to enhance decision-making as well as the time and cost of drug development. 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)	The Binding Site		CorEvitas
Purchase price
Cash paid	$	2,412	$	730
Debt settled	307		184
Cash acquired	(20)		(4)
	$	2,699	$	910
Net assets acquired
Definite-lived intangible assets:
Customer relationships	$	868	$	260
Product technology	162		47
Tradenames	42		—
Backlog	—		46
Goodwill	1,741		627
Net tangible assets	174		(2)
Deferred tax assets (liabilities)	(288)		(68)
	$	2,699	$	910

In addition, in 2023, the company acquired, within the Analytical Instruments segment, a U.S.-based developer of Raman-based spectroscopy solutions for in-line measurement.

The weighted-average amortization periods for definite-lived intangible assets acquired in 2023 are 18 years for customer relationships, 14 years for product technology, 15 years for tradenames, and 13 years for backlog. The weighted average amortization period for all definite-lived intangible assets acquired in 2023 is 17 years.

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. 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.

Unrecognized Tax Benefits

As of June 29, 2024 the company had $0.70 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)	2024
Balance at beginning of year	$	540
Additions for tax positions of current year	9
Additions for tax positions of prior years	199

See Note 10 for fair value information pertaining to the company’s long-term borrowings.

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 29, 2024, 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 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 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 Japanese yen-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 29, 2024.

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 29, 2024, 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.

Commitments and Contingencies

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 29, 2024, there have been no material changes to the accruals for pending environmental-related matters disclosed in the company’s 2023 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 2023 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 29, 2024, 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 2023 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.

The company determines the fair value of its insurance contracts by obtaining the cash surrender value of the contracts from the issuer. The fair value of derivative contracts is the estimated amount that the company would receive/pay upon liquidation of the contracts, taking into account the change in interest rates and currency exchange rates. The company initially measures the fair value of acquisition-related contingent consideration based on amounts expected to be transferred (probability-weighted) discounted to present value. Changes to the fair values of contingent consideration are recorded in selling, general and administrative expense.

In the six-month periods ended June 29, 2024 and July 1, 2023 the company recorded $10 million and $(44) million, respectively, of net gains/(losses) on investments, which are included in other income/(expense) in the accompanying statements of income.

The following table provides a rollforward of the fair value, as determined by level 3 inputs (such as likelihood of achieving production or revenue milestones, as well as changes in the fair values of the investments underlying a recapitalization investment portfolio), of the contingent consideration.

Gains and losses recognized on currency exchange contracts are included in the accompanying statements of income together with the corresponding, offsetting losses and gains on the underlying hedged transactions.

The company uses foreign currency-denominated debt, certain foreign currency-denominated payables, and cross-currency interest rate swaps to partially hedge its net investments in foreign operations against adverse movements in exchange rates. A portion of the company’s euro-denominated senior notes, certain foreign currency-denominated payables, and its cross-currency interest rate swaps have been designated as, and are effective as, economic hedges of part of the net investment in a foreign operation. Accordingly, foreign currency transaction gains or losses due to spot rate fluctuations on the euro-denominated debt instruments and certain foreign currency-denominated payables, and contract fair value changes on the cross-currency interest rate swaps, excluding interest accruals, are included in currency translation adjustment within other comprehensive items and shareholders’ equity.

See Note 1 to the consolidated financial statements for 2023 included in the company’s Annual Report on Form 10-K for additional information on the company’s risk management objectives and strategies.

Fair Value of Other Financial Instruments

The fair value of debt instruments, excluding private placement notes, was determined based on quoted market prices and on borrowing rates available to the company at the respective period ends, which represent level 2 measurements. The fair value of private placement notes was determined based on internally developed pricing models and unobservable inputs, which represent level 3 measurements.

Restructuring and Other Costs

Restructuring and Other Costs

In the first six months of 2024, 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 2024, severance actions associated with facility consolidations and cost reduction measures affected approximately 1% of the company’s workforce.

As of August 2, 2024, the company has identified restructuring actions that will result in additional charges of approximately $80 million, primarily in 2024, and expects to identify additional actions in future periods which will be recorded when specified criteria are met, such as communication of benefit arrangements or when the costs have been incurred.

Restructuring and other costs by segment are as follows:

	Three months ended		Six months ended

Use of Estimates

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.

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.
