Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in

Rules 13a-15(f)

and

15d-15(f)

under the Exchange Act. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on our evaluation under the framework in Internal Control — Integrated Framework (2013), our management, including our chief executive officer and chief financial officer, concluded that our internal control over financial reporting was effective as of December 31, 2024.

The effectiveness of our internal control over financial reporting as of December 31, 2024 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Waters Corporation

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Waters Corporation and its subsidiaries (the “Company”) as of December 31, 2024 and 2023, and the related consolidated statements of operations, of comprehensive income, of stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2024, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in

Internal Control—Integrated Framework

(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in

Internal Control—Integrated Framework

(2013) issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in

accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Product Revenue Recognition

As described in Note 2 to the consolidated financial statements, the Company recognizes revenue upon transfer of control of promised products to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products. The Company recognizes revenue on product sales at the time control of the product transfers to the customer. Certain of the Company’s customers have terms where control of the product transfers to the customer on shipment, while others have terms where control transfers to the customer on delivery. Product sales totaled $1.8 billion for the year ended December 31, 2024.

The principal consideration for our determination that performing procedures relating to product revenue recognition is a critical audit matter is a high degree of auditor effort in performing procedures related to the Company’s product revenue recognition.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to product revenue recognition. These procedures also included, among others, (i) evaluating the recognition of revenue for a sample of transactions by obtaining and inspecting source documents, such as invoices, customer purchase orders, and shipping documents, and (ii) obtaining and inspecting evidence of remittance of cash payment from customers, as applicable, related to product revenue.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1 Description of Business and Organization

Waters Corporation (the “Company,” “we,” “our,” or “us”), a global leader in analytical instruments and software, has pioneered innovations in chromatography, mass spectrometry and thermal analysis serving life, materials and food sciences for more than 65 years. The Company primarily designs, manufactures, sells and services high-performance liquid chromatography (“HPLC”), ultra-performance liquid chromatography (“UPLC” and together with HPLC, referred to as “LC”) and mass spectrometry (“MS”) technology systems and support products, including chromatography columns, other consumable products and comprehensive post-warranty service plans. These systems are complementary products that are frequently employed together

(“LC-MS”)

and sold as integrated instrument systems using common software platforms. LC is a standard technique and is utilized in a broad range of industries to detect, identify, monitor and measure the chemical, physical and biological composition of materials, and to purify a full range of compounds. MS technology, principally in conjunction with chromatography, is employed in drug discovery and development, including clinical trial testing, the analysis of proteins in disease processes (known as “proteomics”), nutritional safety analysis and environmental testing.

LC-MS

instruments combine a liquid phase sample introduction and separation system with mass spectrometric compound identification and quantification. In addition, the Company designs, manufactures, sells and services thermal analysis, rheometry and calorimetry instruments through its TA Instruments product line. These instruments are used in predicting the suitability and stability of fine chemicals, pharmaceuticals, water, polymers, metals and viscous liquids for various industrial, consumer goods and healthcare products, as well as for life science research. The Company is also a developer and supplier of advanced software-based products that interface with the Company’s instruments, as well as other manufacturers’ instruments.

On May 16, 2023, the Company completed the acquisition of Wyatt Technology, LLC and its three operating subsidiaries, Wyatt Technology Europe GmbH, Wyatt Technology France and Wyatt Technology UK Ltd. (collectively, “Wyatt”), for a total purchase price of $1.3

billion in cash. Wyatt is a pioneer in innovative light scattering and field-flow fractionation instruments, software, accessories and services. The acquisition has expanded Waters’ portfolio and increased our exposure to large molecule applications. The Company financed this transaction with a combination of cash on its balance sheet and borrowings under its revolving credit facility. The Company’s financial results for the year ended December 31, 2024 include the financial results of Wyatt for the full year, while the financial results for the year ended December 31, 2023 only include

seven-and-a-half

months of Wyatt’s financial results as the closing of the acquisition occurred during the second quarter of 2023.

2 Basis of Presentation and Summary of Significant Accounting Policies

Use of Estimates

The preparation of consolidated financial statements in conformity with generally accepted accounting principles (“GAAP”) requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent liabilities at the dates of the financial statements. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition, goodwill and intangible assets, income taxes, litigation and inventory valuation. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual amounts may differ from these estimates under different assumptions or conditions.

Risks and Uncertainties

The Company is subject to risks common to companies in the analytical instrument industry, including, but not limited to, global economic and financial market conditions, fluctuations in foreign currency exchange rates,

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

fluctuations in customer demand, development by

its

competitors of new technological innovations, costs of developing new technologies, levels of debt and debt service requirements, risk of disruption, dependence on key personnel, protection and litigation of proprietary technology, shifts in taxable income between tax jurisdictions and compliance with regulations of the U.S.

Food

and Drug Administration and similar foreign regulatory authorities and agencies.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries, which are wholly owned. The Company consolidates entities in which it owns or controls 50% or more of the voting shares. All inter-company balances and transactions have been eliminated.

Translation of Foreign Currencies

The functional currency of each of the Company’s foreign operating subsidiaries is the local currency of its country of domicile, except for the Company’s subsidiaries in Hong Kong and Singapore, where the underlying transactional cash flows are denominated in currencies other than the respective local currency of domicile. The functional currency of the Hong Kong and Singapore subsidiaries is the U.S. dollar, based on the respective entity’s cash flows.

For the Company’s foreign operations, assets and liabilities are translated into U.S. dollars at exchange rates prevailing on the balance sheet date, while revenues and expenses are translated at average exchange rates prevailing during the respective period. Any resulting translation gains or losses are included in accumulated other comprehensive loss in the consolidated balance sheets.

The Company’s net sales derived from operations outside the United States were 68%, 69% and 70% in 2024, 2023 and 2022, respectively. Gains and losses from foreign currency transactions are included primarily in cost of sales in the consolidated statements of operations. In 2024, 2023 and 2022, foreign currency transactions resulted in net losses of $36 million, $16 million and $31 million, respectively.

Seasonality of Business

The Company typically experiences seasonality in its orders that is reflected as an increase in sales in the fourth quarter, as a result of purchasing habits for capital goods of customers that tend to exhaust their spending budgets by calendar

year-end.

Cash, Cash Equivalents and Investments

Cash equivalents represent highly liquid investments, with original maturities of 90 days or less, primarily in bank deposits, U.S. treasury bill money market funds and commercial paper. Investments with longer maturities are classified as investments, and are held primarily in U.S. treasury bills, U.S. dollar-denominated treasury bills and commercial paper, bank deposits and corporate debt securities.

The Company maintains cash balances in various operating accounts in excess of federally insured limits, and in foreign subsidiary accounts in currencies other than the U.S. dollar. As of December 31, 2024 and 2023, $275 million out of $325 million and $321 million out of $396 million, respectively, of the Company’s total cash, cash equivalents and investments were held by foreign subsidiaries. In addition, $226 million out of $325 million and $233 million out of $396 million of cash, cash equivalents and investments were held in currencies other than the U.S. dollar at December 31, 2024 and 2023, respectively.

Accounts Receivable and Allowance for Credit Losses

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The Company has very limited use of rebates and other cash considerations payable to customers and, as a result, the transaction price determination does not have any material variable consideration. The Company does not consider there to be significant concentrations of credit risk with respect to trade receivables due to the short-term nature of the balances, the Company having a large and diverse customer base, and the Company having a strong historical experience of collecting receivables with minimal defaults. As a result, credit risk is considered low across territories and trade receivables are considered to be a single class of financial asset. The allowance for credit losses is based on a number of factors and is calculated by applying a historical loss rate to trade receivable aging balances to estimate a general reserve balance along with an additional adjustment for any specific receivables with known or anticipated issues affecting the likelihood of recovery. Past due balances with a probability of default based on historical data as well as relevant available forward-looking information are included in the specific adjustment. The historical loss rate is reviewed on at least an annual basis and the allowance for credit losses is reviewed quarterly for any required adjustments. The Company does not have any

off-balance

sheet credit exposure related to its customers.

Trade receivables related to instrument sales are collateralized by the instrument that is sold. If there is a risk of default related to a receivable that is collateralized, then the fair value of the collateral is calculated and adjusted for the cost to

re-possess,

refurbish and

re-sell

the instrument. This adjusted fair value is compared to the receivable balance and the difference would be recorded as the expected credit loss.

The following is a summary of the activity of the Company’s allowance for credit losses for the twelve months ended December 31, 2024, 2023 and 2022 (in thousands):

		Balance at Beginning of Period				Additions				Deductions and Other				Balance at End of Period
Allowance for Credit Losses
December 31, 2024		$	19,335			$	3,198			$	(8,264	)		$	14,269
December 31, 2023		$	14,311			$	8,120			$	(3,096	)		$	19,335
December 31, 2022		$	13,228			$	6,509			$	(5,426	)		$	14,311

Concentration of Credit Risk

The Company sells its products and services to a significant number of large and small customers throughout the world, with net sales to the pharmaceutical industry of approximately 58%, 57% and 59% in 2024, 2023 and 2022, respectively. None of the Company’s individual customers accounted for more than 2% of annual Company sales in 2024, 2023 or 2022. The Company performs continuing credit evaluations of its customers and generally does not require collateral, but in certain circumstances may require letters of credit or deposits. Historically, the Company has not experienced significant credit losses.

Inventory

The Company values all of its inventories at the lower of cost or net realizable value on a

first-in,

first-out

basis (“FIFO”).

Income Taxes

As part of the process of preparing the consolidated financial statements, the Company is required to estimate its income taxes in each of the jurisdictions in which it operates. This process involves the Company estimating its

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

income taxes, taking into account the amount, timing and character of taxable income, tax deductions and credits and assessing changes in tax laws, regulations, agreements and treaties. Differing treatment of items for tax and accounting purposes, such as depreciation, amortization and inventory reserves, result in deferred tax assets and liabilities, which are included within the consolidated balance sheets. In the event that actual results differ from these estimates, or the Company adjusts these estimates in future periods, such changes could materially impact the Company’s financial position and results of operations.

The accounting standards for income taxes require that a company continually evaluate the necessity of establishing or changing a valuation allowance for deferred tax assets depending on whether it is more likely than not that the actual benefit of those assets will be realized in future periods.

The Company accounts for its uncertain tax return positions in accordance with the accounting standards for income taxes, which require financial statement reporting of the expected future tax consequences of uncertain tax positions on the presumption that all concerned tax authorities possess full knowledge of those tax positions, as well as all of the pertinent facts and circumstances, but prohibit any discounting of unrecognized tax benefits associated with those positions for the time value of money. The Company classified interest and penalties related to unrecognized tax benefits as a component of the provision for income taxes.

Leases

The Company’s lease portfolio consists primarily of operating leases. The Company’s operating leases consist of property leases for sales, demonstration, laboratory, warehouse and office spaces, automotive leases for sales and service personnel and equipment leases, primarily used in our manufacturing and distribution operations. The Company categorizes leases as either operating or finance leases at the commencement date of the lease. The Company does not have any material financing leases.

The Company makes variable lease payments that do not depend on a rate or index, primarily for items such as real estate taxes and other expenses. These expenses are recorded as variable costs in the period incurred. For the years ended December 31, 2024, 2023 and 2022, variable costs incurred were not material.

The Company’s lease agreements may include tenant improvement allowances, rent holidays, and/or contingent rent provisions as well as a certain number of these leases contain rental escalation clauses that are either fixed or adjusted periodically for inflation of market rates which are factored into our determination of lease payments at lease inception. The Company’s leases also sometimes include renewal options and/or termination options which are included in the determination of the lease term when they are reasonably certain to be exercised.

The Company has lease agreements which contain lease and

non-lease

components, which are accounted for as a single lease component for all underlying classes of assets.

For leases with terms greater than 12 months, the Company records a

right-of-use

asset and lease liability at the present value of lease payments over the term of the leases and records rent expense on a straight-line basis over the lease term. The Company has elected not to apply the recognition requirements to short-term leases with terms less than 12 months. For short-term leases, the Company recognizes lease payments in net income on a straight-line basis over the term of the lease. For the years ended December 31, 2024, 2023

and

2022, costs incurred

related

to short-term leases were not material.

When available, the Company uses the rate implicit in the lease to discount lease payments to determine the present value of the lease liabilities; however, most of the leases do not provide a readily determinable implicit

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

rate and, as required by the accounting guidance, the Company estimates its incremental secured borrowing rate to discount the lease payments based on information available at lease commencement (or, for the leases in existence on the adoption date, the January 1, 2019 information). The Company’s incremental borrowing rate reflects the estimated rate of interest that the Company would pay to borrow on a collateralized basis over a similar term to the lease payments in a similar economic

environment

.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost.

Expenditures

for maintenance and repairs are charged to expense, while the costs of significant improvements are capitalized. Depreciation is provided using the straight-line method over the following estimated useful lives: buildings — fifteen to thirty-nine years; building improvements — five to

ten years; leasehold improvements — the shorter of the economic useful life or life of lease; and production and other equipment —

three

to ten years. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are eliminated from the consolidated balance sheets and related gains or losses are reflected in the consolidated statements of operations.

Asset Impairments

The Company reviews its long-lived assets for impairment in accordance with the accounting standards for property, plant and equipment. Whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable, the Company evaluates the recoverability of the carrying value of the asset based on the expected future cash flows, relying on a number of factors, including, but not limited to, operating results, business plans, economic projections and anticipated future cash flows. If the asset is deemed not recoverable, it is written down to fair value and the impairment is recorded in the consolidated statements of operations.

During 2022, the Company recorded a total

non-cash

charge of $6

million in other income (expense), net in the consolidated statement of operations for the impairment of various equity investments without readily determinable fair values accounted for under the measurement alternative or the equity method of accounting. The impairments resulted from the substantial doubt of the investee’s ability to continue as a going concern.

Business Combinations and Asset Acquisitions

The Company accounts for business acquisitions under the accounting standards for business combinations. The results of each acquisition are included in the Company’s consolidated results as of the acquisition date and the purchase price of an acquisition is allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values. Any excess of the fair value consideration transferred over the estimated fair values of the net assets acquired is recognized as goodwill. We use assumptions and estimates in determining the fair value of assets acquired and liabilities assumed. The determination of the fair value of intangible assets, which represents a significant portion of the purchase price in our recent acquisition of Wyatt, requires the use of significant judgment with regard to (i) the fair value; and (ii) whether such intangibles are amortizable or

non-amortizable

and, if the former, the period and the method by which the intangible asset will be amortized. We utilize commonly accepted valuation techniques, such as the income, cost and market approaches, as appropriate, in establishing the fair value of intangible assets. Typically, key assumptions include projections of cash flows that arise from identifiable intangible assets of acquired businesses as well as discount rates based on an analysis of the weighted average cost of capital, adjusted for specific risks associated with the assets.

The customer relationship intangible assets were the most significant identifiable assets acquired in the acquisition of Wyatt. The customer relationships were valued using the multi-period excess earnings method under the income approach. Our cash flow projections for the customer relationships acquired included significant judgments and assumptions related to customer attrition rate, discount rate, and forecasted revenues.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Goodwill and Other Intangible Assets

Goodwill and indefinite-lived intangible assets are not amortized, but are evaluated for impairment on an annual basis, or on an interim basis when events or changes in circumstances indicate that the carrying value may not be recoverable. In assessing the recoverability of goodwill and indefinite-lived intangible assets, we must make assumptions regarding the estimated future cash flows, including forecasted revenue growth and the discount rate to determine the fair value of these assets. If these estimates or their related assumptions change in the future, we may be required to record impairment charges against these assets in the reporting period in which the impairment is determined.

We test goodwill for impairment at the reporting unit level, which is the operating segment or one level below an operating segment. We have the option of performing a qualitative assessment to determine whether further impairment testing is necessary before performing the quantitative assessment. If as a result of the qualitative assessment, it is

more-likely-than-not

that the fair value of a reporting unit is less than its carrying amount, a quantitative impairment test will be required. Otherwise, no further testing will be required. If a quantitative impairment test is performed, we compare the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. Estimating the fair value of the reporting units requires significant judgment by management. If the carrying amount of a reporting unit exceeds the fair value of the reporting unit, an impairment charge is recognized for the amount by which the carrying value amount exceeds the reporting unit’s fair value up to the total amount of goodwill allocated to the reporting unit. The Company performs an annual goodwill impairment assessment for its reporting units as of December 31 each year. The Company has two reporting units: Waters and TA. Goodwill is allocated to the reporting units at the time of acquisition.

The Company’s intangible assets include purchased technology; capitalized software; costs associated with acquiring Company patents, trademarks and intellectual properties, such as licenses; and acquired IPR&D. Purchased intangibles are recorded at their fair market values as of the acquisition date and amortized over their estimated useful lives, ranging from

one

to fifteen years. Other intangibles are amortized over a period ranging from

one

to ten years. Acquired IPR&D is amortized from the date of completion of the acquired program over its estimated useful life.

Goodwill totaled $1.3 billion as of both December 31, 2024 and 2023, respectively. Net intangible assets and long-lived assets amounted to $568 million and $651 million, as of December 31, 2024, respectively, and $629 million and $639 million as of December 31, 2023, respectively.

Software Development Costs

The Company capitalizes internal and external software development costs for products offered for sale in accordance with the accounting standards for the costs of software to be sold, leased, or otherwise marketed. Capitalized costs are amortized to cost of sales over the period of economic benefit, which approximates a straight-line basis over the estimated useful lives of the related software products, generally

three

to

ten years

. The Company capitalized $34 million, $44 million and $46 million of direct expenses that were related to the development of software in 2024, 2023 and 2022, respectively. Net capitalized software included in intangible assets totaled $154 million and $165 million at December 31, 2024 and 2023, respectively. See Note 7, Goodwill and Other Intangibles.

The Company capitalizes software development costs for internal use. Capitalized internal software development costs are amortized over the period of economic benefit, which approximates a straight-line basis over ten years.

Net capitalized internal software included in property, plant and equipment totaled $

56 million and $

million at December 31, 2024 and 2023, respectively.

Other Investments

The Company accounts for its investments that represent less than twenty percent ownership, and for which the Company does not have the ability to exercise significant influence, using the accounting standards for

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

investments in equity securities. Investments for which the Company does not have the ability to exercise significant influence, and for which there is not a readily determinable market value, are accounted for at cost, adjusted for subsequent observable price changes as applicable. The Company periodically evaluates the carrying value of its investments for which the Company does not have the ability to exercise significant influence, and for which there is not a readily determinable fair value and carries them at cost, less impairment, adjusted for subsequent observable price changes. For equity investments in which the Company has the ability to exercise significant influence over operating and financial policies of the investee, the equity method of accounting is used. The Company’s share of net income or losses of equity method investments is included in the consolidated statements of operations and was not material in any period presented.

During the year ended December 31, 2024, the Company received no proceeds from, and made $1 million of investments in, unaffiliated companies. During the year ended December 31, 2023

,

the Company received $1 million in proceeds from, and made no investments in, unaffiliated companies. During the year ended December 31, 2022

,

the Company received $10 million in proceeds from, and made investments of $1 million in, unaffiliated companies.

In 2022, the Company recorded a realized gain of $7 million in other income (expense), net in the consolidated statement of operations due to the sales of various equity investments as well as incurring $6 million in impairment losses. The Company also recognized an additional $2 million

non-cash

gain on the cashless exercise of a warrant.

Fair Value Measurements

In accordance with the accounting standards for fair value measurements and disclosures, certain of the Company’s assets and liabilities are measured at fair value on a recurring basis as of December 31, 2024 and 2023. Fair values determined by Level 1 inputs utilize observable data, such as quoted prices in active markets. Fair values determined by Level 2 inputs utilize data points other than quoted prices in active markets that are observable either directly or indirectly. Fair values determined by Level 3 inputs utilize unobservable data points for which there is little or no market data, which require the reporting entity to develop its own assumptions.

The following table represents the Company’s assets and liabilities measured at fair value on a recurring basis at December 31, 2024 (in thousands):

		Total at December 31, 2024				Quoted Prices in Active Markets for Identical Assets (Level 1)				Significant Other Observable Inputs (Level 2)				Significant Unobservable Inputs (Level 3)

Fair Value of 401(k) Restoration Plan Assets

The 401(k) Restoration Plan is a nonqualified defined contribution plan and the assets were held in registered mutual funds and have been classified as Level 1. The fair values of the assets in the plan are determined through market and observable sources from daily quoted prices on nationally recognized securities exchanges.

Fair Value of Cash Equivalents, Investments, Foreign Currency Exchange Contracts, Interest Rate Cross-Currency Swap Agreements and Interest Rate Swap Cash Flow Hedges

The fair values of the Company’s cash equivalents, investments, foreign currency exchange contracts, interest rate cross-currency swap agreements and interest rate swap cash flow hedges are determined through market and observable sources and have been classified as Level 2. These assets and liabilities have been initially valued at the transaction price and subsequently valued, typically utilizing third-party pricing services. The pricing services use many inputs to determine value, including reportable trades, benchmark yields, credit spreads, broker/dealer quotes, current spot rates and other industry and economic events. The Company validates the prices provided by third-party pricing services by reviewing their pricing methods and obtaining market values from other pricing sources.

Fair Value of Other Financial Instruments

The Company’s accounts receivable and accounts payable are recorded at cost, which approximates fair value due to their short-term nature. The carrying value of the Company’s variable interest rate debt approximates fair value due to the variable nature of the interest rate. The carrying value of the Company’s fixed interest rate debt was $1.3 billion at both December 31, 2024 and 2023. The fair value of the Company’s fixed interest rate debt was estimated using discounted cash flow models, based on estimated current rates offered for similar debt under current market conditions for the Company. The fair value of the Company’s fixed interest rate debt was e

stimate

d to be $1.1

billion

and $1.2 billion at December 31, 2024 and 2023, respectively, using Level 2 inputs.

Derivative Transactions

The Company is a global company that operates in over 35 countries and, as a result, the Company’s net sales, cost of sales, operating expenses and balance sheet amounts are significantly impacted by fluctuations in foreign

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

currency exchange rates. The Company is exposed to currency price risk on foreign currency exchange rate fluctuations when it translates its

non-U.S.

dollar foreign subsidiaries’ financial statements into U.S. dollars and when any of the Company’s subsidiaries purchase or sell products or services in a currency other than its own currency.

The Company’s principal strategies in managing exposures to changes in foreign currency exchange rates are to (1) naturally hedge the foreign-currency-denominated liabilities on the Company’s balance sheet against corresponding assets of the same currency, such that any changes in liabilities due to fluctuations in foreign currency exchange rates are typically offset by corresponding changes in assets and (2) mitigate foreign exchange risk exposure of international operations by hedging the variability in the movement of foreign currency exchange rates on a portion of its euro-denominated and

yen-denominated

net asset investments. The Company presents the derivative transactions in financing activities in the statement of cash flows.

Foreign Currency Exchange Contracts

The Company does not specifically enter into any derivatives that hedge foreign-currency-denominated operating assets, liabilities or commitments on its balance sheet, other than a portion of certain third-party accounts receivable and accounts payable, and the Company’s net worldwide intercompany receivables and payables, which are eliminated in consolidation. The Company periodically aggregates its net worldwide balances by currency and then enters into foreign currency exchange contracts that mature within 90 days to hedge a portion of the remaining balance to minimize some of the Company’s currency price risk exposure. The foreign currency exchange contracts are not designated for hedge accounting treatment. Principal hedged currencies include the euro, Japanese yen, British pound, Mexican peso and Brazilian real.

Cash Flow Hedges

The Company’s Credit Facility is a variable borrowing and has interest payments based on a contractually specified interest rate index. The contractually specified index on the Credit Facility is the

3-month

Term SOFR. The variable rate interest payments create interest risk for the Company as interest payments will fluctuate based on changes in the contractually specified interest rate index over the life of the Credit Facility. In order to reduce interest rate risk, the Company has entered in interest rate swaps with an aggregate notional value of $150 million to effectively

lock-in

the forecasted interest payments on the variable rate borrowing over its term. The interest rate swaps represent cash flow hedges and are assessed for hedge effectiveness each reporting period. When the hedge relationship is highly effective at achieving offsetting changes in cash flows, the Company will record the entire change in fair value of the interest rate swaps in accumulated other comprehensive loss. The amount in accumulated other comprehensive loss is reclassified to income in the period that the underlying transaction impacts consolidated income. If it becomes probable that the forecasted transaction will not occur, the hedge relationship will be

de-designated

and amounts accumulated in other comprehensive loss will be reclassified to income in the current period. Interest settlements due to benchmark interest rate changes are recorded in interest income or interest expense. For the twelve months ended December 31, 2024, the Company did not have any cash flow hedges that were deemed ineffective.

Interest Rate Cross-Currency Swap Agreements

As of December 31, 2024, the Company had entered into interest rate cross-currency swap derivative agreements with durations up to three years with an aggregate notional value of $625 million to hedge the variability in the movement of foreign currency exchange rates on a portion of its euro-denominated and

yen-denominated

net asset investments. Under hedge accounting, the change in fair value of the derivative that relates to changes in the foreign currency spot rate are recorded in the currency translation adjustment in other comprehensive income and remain in accumulated other comprehensive loss in stockholders’ equity until the sale or substantial

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

liquidation of the foreign operation. The difference between the interest rate received and paid under the interest rate cross-currency swap derivative agreement is recorded in interest income in the statement of operations.

The Company’s foreign currency exchange contracts, interest rate cross-currency swap agreements and interest rate swap agreements designated as cash flow hedges included in the consolidated balance sheets are classified as follows (in thousands):

Stockholders’ Equity

In December 202

, the Company’s Board of Directors authorized the extension of the existing share repurchase program through January 21, 202

. The Company’s remaining authorization is $1.0 billion. During 2023 and 2022, the Company repurchased 0.2 million and 2.0 million shares of the Company’s outstanding common stock at a cost of $58 million and $616

million, respectively, under authorized share repurchase programs. The Company did not make any open market share repurchases in 2024. In addition, the Company repurchased

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

$13 million, $12 million and $11 million of common stock related to the vesting of restricted stock units during the years ended December 31, 2024, 2023 and 2022, respectively. As of December 31, 2

4, the Company has a total of $1.0 billion authorized for future repurchases.

Revenue Recognition

The Company recognizes revenue upon transfer of control of promised products and services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company generally enters into contracts that include a combination of products and services. Revenue is allocated to distinct performance obligations and is recognized net of allowances for returns and discounts.

The Company recognizes revenue on product sales at the time control of the product transfers to the customer. Certain of the Company’s customers have terms where control of the product transfers to the customer on shipment, while others have terms where control transfers to the customer on delivery. All incremental costs of obtaining a contract are expensed as and when incurred if the expected amortization period of the asset that would have been recognized is one year or less. Shipping and handling costs are included as a component of cost of sales. In situations where the control of the goods transfers prior to the completion of the Company’s obligation to ship the products to its customers, the Company has elected the practical expedient to account for the shipping services as a fulfillment cost. Accordingly, such costs are recognized when control of the related goods is transferred to the customer. In more rare situations, the Company has revenue associated with products that contain specific customer acceptance criteria and the related revenue is not recognized before the customer acceptance criteria are satisfied. The Company elected to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with specific revenue-producing transactions and collected by the Company from a customer.

Generally, the Company’s contracts for products include a performance obligation related to installation. The Company has determined that the installation represents a distinct performance obligation and revenue is recognized separately upon the completion of installation. The Company determines the amount of the transaction price to allocate to the installation service based on the standalone selling price of the product and the service, which requires judgment. The Company determines the relative standalone selling price of installation based upon a number of factors, including hourly service billing rates and estimated installation hours. In developing these estimates, the Company considers past history, competition, billing rates of current services and other factors.

The Company has sales from standalone software, which are included in product revenue. These arrangements typically include software licenses and maintenance contracts, both of which the Company has determined are distinct performance obligations. The Company determines the amount of the transaction price to allocate to the license and maintenance contract based on the relative standalone selling price of each performance obligation. Software license revenue is recognized at the point in time when control has been transferred to the customer. The revenue allocated to the software maintenance contract is recognized on a straight-line basis over the maintenance period, which is the contractual term of the contract, as a time-based measure of progress best reflects the Company’s performance in satisfying this obligation. Unspecified rights to software upgrades are typically sold as part of the maintenance contract on a

when-and-if-available

basis.

Payment terms and conditions vary among the Company’s revenue streams, although terms generally include a requirement of payment within 30 to 60 days of product shipment. Prior to providing payment terms to customers, an evaluation of their credit risk is performed. Returns and customer credits are infrequent and insignificant and are recorded as a reduction to sales. Rights of return are not included in sales arrangements and, therefore, there is minimal variable consideration included in the transaction price of our products.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Service revenue includes (1) service and software maintenance contracts and (2) service calls (time and materials). Instrument service contracts and software maintenance contracts are typically annual contracts, which are billed at the beginning of the contract or maintenance period. The amount of the service and software maintenance contract is recognized on a straight-line basis to revenue over the maintenance service period, which is the contractual term of the contract, as a time-based measure of progress best reflects the Company’s performance in satisfying this obligation. There are no deferred costs associated with the service contract, as the cost of the service is recorded when the service is performed. Service calls are recognized to revenue at the time a service is performed.

Product Warranty Costs

The Company accrues estimated product warranty costs at the time of sale, which are included in cost of sales in the consolidated statements of operations. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its component suppliers, the Company’s warranty obligation is affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. The amount of the accrued warranty liability is based on historical information, such as past experience, product failure rates, number of units repaired and estimated costs of material and labor. The liability is reviewed for reasonableness at least quarterly.

The following is a summary of the activity of the Company’s accrued warranty liability for the twelve months ended December 31, 2024, 2023 and 2022 (in thousands):

		Balance at Beginning of Period				Accruals for Warranties				Settlements Made				Balance at End of Period

Restructuring

In March 2024, the Company implemented a reduction in workforce that impacted approximately

2% of the Company’s employees, primarily in China, where there had been a significant decline in sales as a result of lower customer demand. As a result, the Company incurred approximately $9

million of severance-related costs.

D

uring 2024, the Company paid $

million of severance-related costs in connection with the workforce reduction that occurred in

March 2024 and

July 2023. The accrued restructuring expense was approximately $

million at December 31, 2024 and $

million at December 31, 2023 and included in other current liabilities on the consolidated balance sheets.

Recently Adopted Accounting Standards

In March 2020, accounting guidance was issued that facilitates the effects of reference rate reform on financial reporting. The amendments in the update provide optional guidance for a limited period of time to ease the potential burden in accounting for or recognizing the effects of reference rate reform on financial reporting and apply to all entities, subject to meeting certain criteria, that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. In January of 2021, an update was issued to clarify that certain optional expedients and exceptions under the reference rate reform guidance for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. Specifically, certain provisions in the reference rate reform guidance, if elected by an entity, apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. This temporary guidance is effective for all entities as of March 12, 2020, through December 31, 2022. In December 2022, an update was issued because the cessation date for overnight LIBOR rates being published was extended to June 30, 2023, which was beyond the current expiration date of this guidance. The update extended the sunset date to December 31, 2024. The Company may elect to apply this guidance for all contract modifications or eligible hedging relationships during that time period subject to certain criteria. The Company did not elect to adopt this guidance because the Company did not have material reference rate exposure which required utilizing the guidance under this accounting pronouncement.

In November 2023, accounting guidance was issued that requires additional disclosures of reportable segment information. The guidance requires that public entities disclose, on an annual and interim basis (1) significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss, (2) an amount for other segment items by reportable segment and a description of its composition (the other segment items category is the difference

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

between segment revenue less the segment expenses disclosed under the significant expense principle and each reported measure of segment profit or loss), (3) provide all annual disclosures about a reportable segment’s profit or loss and assets currently required by Topic 280 in interim periods, (4) clarify that if the CODM uses more than one measure of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources, a public entity may report one or more of those additional measures of segment profit. However, at least one of the reported segment profit or loss measures (or the single reported measure, if only one is disclosed) should be the measure that is most consistent with the measurement principles used in measuring the corresponding amounts in the public entity’s consolidated financial statements, (5) the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources, and (6) if a public entity has a single reportable segment to provide all the disclosures required by the amendments in this update and all existing segment disclosures in Topic 280. The amendments in this update do not change how operating segments are identified or aggregated nor how the quantitative thresholds are applied to determine its reportable segments. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments in this update should be applied retrospectively to all prior periods presented in the financial statements. Upon transition, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. The Company has adopted this accounting standard update and included its significant expense categories in Note 17 “Business Segment Information”.

Recently Issued Accounting Standards

In December 2023, accounting guidance was issued to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this update change disclosure requirements related to the rate reconciliation, income taxes paid and other disclosures. For the rate reconciliation the amendments require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. For income taxes paid the amendments require that all entities disclose on an annual basis the following information; (1) the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes, (2) the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5 percent of total income taxes paid (net of refunds received). Finally, for other disclosures the amendments require that all entities disclose the following information: (1) income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign, and (2) income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. This update also eliminates the requirement for all entities to (1) disclose the nature and estimate of the range of the reasonably possible change in the unrecognized tax benefits balance in the next 12 months or (2) make a statement that an estimate of the range cannot be made. As well as removing the requirement to disclose the cumulative amount of each type of temporary difference when a deferred tax liability is not recognized because of the exceptions to comprehensive recognition of deferred taxes related to subsidiaries and corporate joint ventures. The amendments in this update are effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments in this update should be applied on a prospective basis and retrospective application is permitted. The Company does not believe this accounting standard update will have a material impact on the Company’s financial position, results of operations and cash flows. The Company is currently evaluating the impact the adoption of this accounting standard update will have on our footnote disclosures.

In November 2024, accounting guidance was issued to improve disclosures of expenses and address requests from investors for more detailed information about the types of expenses (including purchases of

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

inventory, employee compensation, depreciation, amortization, and depletion) in commonly presented expense captions (such as cost of sales, SG&A, and research and development). This incremental information will allow investors to better understand the components of an entity’s expenses, make their own judgements about the entity’s performance, and more accurately forecast expenses which will allow investors to better assess an entity’s prospects for future cash flows. The amendments in this update require disclosure, in the notes to the financial statements, of specified information about certain costs and expenses. The amendments require that at each interim and annual reporting period an entity (1) disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization included in each relevant expense caption. A relevant expense caption is an expense caption presented on the face of the income statement within continuing operations that contains any of the expense categories listed in (a) — (d), (2) include certain amounts that are already required to be disclosed under current generally accepted accounting principles (GAAP) in the same disclosure as the other disaggregation requirements, (3) disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively, (4) disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. The amendments in this update are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The amendments in this update should be applied either (1) prospectively to financial statements issued for reporting periods after the effective date of this update or (2) retrospectively to any or all prior periods presented in the financial statements. The Company does not believe this accounting standard update will have a material impact on the Company’s financial position, results of operations and cash flows. The Company is currently evaluating the impact the adoption of this accounting standard update will have on our footnote disclosures.

3 Revenue Recognition

The Company’s deferred revenue liabilities in the consolidated balance sheets consist of the obligation on instrument service contracts and customer payments received in advance, prior to transfer of control of the instrument. The Company records deferred revenue primarily related to its service contracts, where consideration is billable at the beginning of the service period.

6 Acquisitions

On May 16, 2023, the Company acquired all of the issued and outstanding equity interests of Wyatt for $1.3

billion, net of cash acquired. Wyatt is a pioneer in innovative light scattering and field-flow fractionation instruments, software, accessories and services. The acquisition has expanded Waters’ portfolio and increased our exposure to large molecule applications.

The Company allocated the purchase price of the acquisition to identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. The Company allocated $

million of

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

the purchase price to intangible assets comprised of developed technology, trade name and customer relationships. The developed technology and customer relationships will be amortized over ten years and the trade name will be amortized over five years.

The intangible assets were valued with input from valuation specialists. The Company used variations of the income approach, which uses Level 3 inputs, in determining the fair value of intangible assets acquired in the Wyatt acquisition. Specifically, the customer relationships were valued using the multi-period excess earnings method under the income approach. The Company utilized the relief from royalty method to determine the fair value of the tradename and the developed technology. The following table presents the allocation of the purchase price to the estimated fair values of the assets acquired and liabilities assumed on the closing date of May 16, 2023 (in thousands):

Purchase Price
Cash paid		$	1,307,978
Less: cash acquired			(25,624	)
Net cash consideration			1,282,354
Identifiable Net Assets (Liabilities) Acquired
Accounts receivable			20,099
Inventory			14,706
Deferred tax assets			11,335
Prepaid and other assets			1,096
Property, plant and equipment			9,056
Operating lease assets			5,204
Intangible assets			418,100
Accounts payable and accrued expenses			(31,664	)
Operating lease liabilities			(5,204	)
Tax liabilities			(3,917	)
Deferred revenue			(15,219	)
Other liabilities			(5,728	)
Total identifiable net assets acquired			417,864
Goodwill			864,490
Cash consideration paid		$	1,282,354

The details of the purchase price allocated to the intangible assets acquired and the estimated useful lives are as follows (dollars in thousands):

		Amount				Weighted-Average Life
Developed technology		$	80,000				10 years
Customer relationships			330,600				10 years
Trade name			7,500				5 years
Total			$418,100

The Company allocated $864 million of the purchase price to goodwill which is primarily deductible for tax purposes and has been allocated to the Waters Division operating segment. The goodwill arising from the acquisition consists largely of the value of intangible assets that do not qualify for separate recognition such as workforce in place and cash flows from the integration of acquired technology, distribution channels and products with the Company’s products, which are higher than if the acquired companies’ technology, customer access or products were utilized on a stand-alone basis.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The Company’s consolidated results include net sales of $111 million during fiscal 2024 and $73 million during the period in fiscal 2023 following the

Wyatt

acquisition that closed on May 16, 2023. For each of those periods, Wyatt operated at an immaterial net loss after purchased intangibles amortization, the retention

expenses

and interest expense. The Company also incurred transaction related costs of $

million during the twelve months ended December 31, 2023, in connection with the Company’s acquisition of Wyatt, which are recorded in selling and administrative expenses in the consolidated statement of operations.

Unaudited Pro Forma Financial Information

The following unaudited pro forma information is presented for illustrative purposes only. It is not necessarily indicative of the actual results of operations that actually would have been realized had the entities been a single company as of January 1, 2022 or the future operating results of the combined entity. The unaudited pro forma information does not give effect to the potential impact of current financial conditions, regulatory matters or any anticipated synergies that may be associated with the acquisition. The unaudited pro forma information also does not include any integration costs that the Company may incur related to the acquisition as part of combining the operations of the companies.

The following unaudited pro forma information shows the results of the Company’s operations for the twelve months ended December 31, 2023 and 2022, as if the acquisition had occurred on January 1, 2022 (in thousands):

		December 31, 2023				December 31, 2022
Revenue		$	2,995,001			$	3,086,281
Net income			658,431				651,869

To reflect the acquisition of Wyatt as if it had occurred on January 1, 2022, the unaudited pro forma information includes adjustments to reflect, among other things, the incremental intangible asset amortization to be incurred based on the values of each identifiable intangible asset of Wyatt and the interest expense from debt financings obtained to partially fund the cash consideration transferred. Pro forma adjustments were tax effected at the Company’s historical statutory rates in effect for the respective periods.

Pro forma net income for the twelve months ended December 31, 2023, was adjusted to exclude certain

non-recurring

expenses related to transaction costs incurred and the fair value adjustment of inventory. These

non-recurring

expenses were reclassified to the prior period and included in the pro forma net income for the twelve months ended December 31, 2023 and 2022.

In conjunction with the Wyatt acquisition, the Company entered into retention agreements with certain employees, in which the Company agreed to pay a total of $40 million, in two equal installments upon the first and second anniversary of the acquisition date. As these employees are earning their individual cash award by providing service over the

two-year

period that benefit

s

the Company, the $40 million will be recognized within total costs and operating expenses in the consolidated statements of operations over the

two-year

service period. The Company has recorded $18 million and $19 million of expense in the consolidated statement of operations for the twelve months ended December 31, 2024 and 2023, respectively.

On January 31, 2022, the Company completed an asset acquisition in which the charge detection mass spectrometry technology (“CDMS technology”) assets of Megadalton Solutions, Inc. (“Megadalton”) were acquired for approximately $10 million in total purchase price, of which $5 million was paid at closing and

the remaining

$4

million will be paid in the future at various dates through 2029. This CDMS technology makes it possible to analyze extremely large proteins and protein complexes used in cell and gene therapies that would otherwise be difficult to analyze with conventional mass spectrometry. Once this technology is further

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

developed, it will extend the capabilities of our mass spectrometry portfolio for a broader set of applications, and as such, the cost of this technology asset has been accounted for as Acquired

In-Process Research

and Development and expensed in costs and operating expenses in the statement of operations.

The Company capitalized $40 million, $468 million and $54 million of intangible assets for the years ended December 31, 2024, 2023 and 2022, respectively. The gross carrying value of intangible assets and accumulated amortization for intangible assets decreased by $37 million and $39 million, respectively, in the year ended December 31, 2024 due to the effects of foreign currency translation. Amortization expense for intangible assets was $105 million, $81 million and $58 million for the years ended December 31, 2024, 2023 and 2022, respectively. In addition, in the year ended December 31, 2023, the company wrote off a $4 million intangible asset that was fully amortized.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The Company’s effective tax rate was 15.5%, 12.8% and 15.5

% for the years ended December 31, 2024, 2023 and 2022, respectively. The increase in the Company’s effective tax rate in 2024 can primarily be attributed to the recognition of a previously unrecognized tax benefit of $

million as a result of the completion of a tax examination in 2023

.

The Company’s effective income tax rate differs from the U.S. federal statutory rate each year due to differences in the proportionate amounts of

pre-tax

income recognized in jurisdictions with different effective tax rates and the items discussed below. Included in the 2024 net effect of foreign operations is the impact of the Pillar Two system of global minimum tax rules, which did not have a material impact.

The four principal jurisdictions in which the Company manufactures are the U.S., Ireland, the U.K. and Singapore, where the statutory tax rates were 21%, 12.5%, 25% and 17

%, respectively, as of December 31, 2024. The Company has a Development and Expansion Incentive in Singapore that provides a concessionary income tax rate of

% on certain types of income for the period April 1, 2021 through March 31, 2026. The effect of applying these concessionary income tax rates rather than the statutory tax rate to income arising from qualifying activities in Singapore increased the Company’s net income by $

14 million, $16 million and $20 million and increased the Company’s net income per diluted share by $0.24, $0.27 and $0.33 for the years ended December 31, 2024, 2023 and 2022, respectively.

During 2024, the Company’s effective tax rate differed from the 21

% U.S. statutory tax rate primarily due to the jurisdictional mix of earnings,

a

$

million provision related to the GILTI tax, including the impact of capitalizing research and development expenditures pursuant to IRC Section 174, and a tax benefit of $

3 million on stock-based compensation.

The 2023 effective tax rate differed from the 21% U.S. statutory tax rate primarily due to the jurisdictional mix of earnings, a $18 million recognition of a previously unrecognized tax benefit as a result of the completion of a tax examination, a $15 million provision related to the GILTI tax, including the impact of capitalizing research and development expenditures pursuant to IRC Section 174 and a tax benefit of $3 million on stock-based compensation.

The 2022 effective tax rate differed from the 21% U.S. statutory tax rate primarily due to the jurisdictional mix of earnings, an $18 million provision related to the GILTI tax and a tax benefit of $7 million on stock-based compensation.

The Company recorded a tax provision of $3 million, $4 million and $4 million for 2024, 2023 and 2022, respectively, for future withholding taxes and U.S. state taxes on the repatriation of 2024, 2023 and 2022 undistributed earnings.

The Company has gross foreign net operating losses of $505 million, of which $176 million do not expire under current laws

,

$42

million start expiring in 2025 and $287 million start expiring in 2041. As of December 31, 2024, the Company has provided a deferred tax valuation allowance of

$119 million, of which $113 million relates to certain foreign net operating losses. The Company’s net deferred tax assets associated with net operating losses and tax credit carryforwards are approximately $5 million as of December 31, 2024, which represent the future tax benefit of foreign net operating loss carryforwards that do not expire under current law.

The Company accounts for its uncertain tax return positions in accordance with the accounting standards for income taxes, which require financial statement reporting of the expected future tax consequences of uncertain tax reporting positions on the presumption that all concerned tax authorities possess full knowledge of those tax reporting positions, as well as all of the pertinent facts and circumstances, but prohibit any discounting of unrecognized tax benefits associated with those reporting positions for the time value of money. The Company

continues

to classify interest and penalties related to unrecognized tax benefits as a component of the provision for income taxes.

The following is a summary of the activity of the Company’s gross unrecognized tax benefits, excluding interest and penalties, for the year ended December 31, 2024, 2023 and 2022 (in thousands):

		2024				2023				2022
Balance at the beginning of the period		$	14,323			$	29,019			$	28,692

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

As of 2024, the total amount of gross unrecognized tax benefits was $18

million, all of which, if recognized, would impact the Company’s effective tax rate. The Company is subject to various foreign audits and inquiries, and we currently do not expect any material adjustments.

With limited exceptions, the Company is no longer subject to tax audit examinations in significant jurisdictions for the years ended on or before December 31, 2019. The Company continuously monitors the lapsing of statutes of limitations on potential tax assessments for related changes in the measurement of unrecognized tax benefits, related net interest and penalties and deferred tax assets and liabilities.

As of December 31, 2024, the Company expects to record additional reductions in the measurement of its unrecognized tax benefits and related net interest and penalties of approximately $1 million within the next twelve months due to potential tax audit settlements and the lapsing of statutes of limitations on potential tax assessments. The Company does not expect to record any other material reductions in the measurement of its unrecognized tax benefits within the next twelve months.

The following is a summary of the activity of the Company’s valuation allowance for the years ended December 31, 2024, 2023 and 2022 (in thousands):

		Balance at Beginning of Period				Charged to Provision for Income Taxes*				Other**				Balance at End of Period
Valuation allowance for deferred tax assets:
2024		$	57,873			$	64,310			$	(2,719	)		$	119,464
2023		$	54,300			$	1,467			$	2,106			$	57,873
2022		$	58,834			$	(1,647	)		$	(2,887	)		$	54,300

*	These amounts have been recorded as part of the income statement provision for income taxes. The income statement effects of these amounts have largely been offset by amounts related to changes in other deferred tax balance sheet accounts. The increase in the 2024 charge to the provision for income taxes can be attributed to an increase in foreign net operating losses.

**	The changes in the valuation allowance during the years ended December 31, 2024, 2023 and 2022 are primarily due to the effect of foreign currency translation on a valuation allowance related to a net operating loss carryforward.

10 Litigation

From time to time, the Company and its subsidiaries are involved in various litigation matters arising in the ordinary course of business. The Company believes it has meritorious arguments in its current litigation matters and believes any outcome, either individually or in the aggregate, will not be material to the Company’s financial position, results of operations or cash flows. During the year ended December 31, 2024, the Company recorded $12 million and paid $10 million of patent litigation settlement and related costs.

11 Leases

As of December 31, 2024 and 2023, the Company had lease agreements that expire at various dates through 2034, with weighted-average remaining lease terms of 3.6 years and 4.5 years, respectively. Rental expense was

$39 million, $38 million and $36 million for the years ended December 31, 2024, 2023 and 2022, respectively. As of December 31, 2024 and 2023, the weighted-average discount rates used to determine the present value of lease liabilities were 4.41% and 4.15% respectively. During the years ended December 31, 2024, 2023 and 2022, cash paid for amounts included in the measurement of lease liabilities in operating activities in the statement of cash flows was $39 million, $38 million and $36 million, respectively. The Company recorded

a

$3

million decrease in right-of-use assets in exchange for new operating lease liabilities during the year ended December 31, 2024

. The Company recorded a

12 Other Commitments and Contingencies

The Company licenses certain technology and software from third parties in the

ordinary

course of business. Future minimum fees payable under existing technology and software license agreements as of December 31, 2024 are $98 million for the years ended December 31, 2025 and thereafter.

The software license agreements are long-term contracts and are not cancellable by the Company until the expiration of their initial term. The amounts owed under these contracts are included in both other assets and other long-term liabilities on the Company’s consolidated balance sheet as of December 31, 2024. In December 2024, the Company’s Board of Directors approved the implementation of a new worldwide enterprise resource planning system (“ERP”). The Company anticipates spending approximately

$130 million on the ERP implementation over the next three years. The Company expects to use existing cash and its credit facility to fund the ERP implementation.

The Company enters into standard indemnification agreements in its ordinary course of business. Pursuant to these agreements, the Company indemnifies, holds harmless and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the Company’s business partners or customers, in connection with patent, copyright or other intellectual property infringement claims by any third party with respect to its current products, as well as claims relating to property damage or personal injury resulting from the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

performance of services by the Company or its subcontractors. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited. Historically, the Company’s costs to defend lawsuits or settle claims relating to such indemnity agreements have been minimal and management accordingly believes the estimated fair value of these agreements is immaterial.

13 Stock-Based Compensation

In May 2020, the Company’s shareholders approved the Company’s 2020 Equity Incentive Plan (“2020 Plan”). As of December 31, 2024, the 2020 Plan has 6.0 million shares available for grant in the form of incentive or

non-qualified

stock options, stock appreciation rights (“SARs”), restricted stock or other types of awards (e.g. restricted stock units and performance stock units). The Company issues new shares of common stock upon exercise of stock options, restricted stock unit conversion or performance stock unit conversion. Under the 2020 Plan, the exercise price for stock options may not be less than the fair market value of the underlying stock at the date of grant. The 2020 Plan is scheduled to terminate on May 13, 2030. Options generally will expire no later than ten years after the date on which they are granted and will become exercisable as directed by the Compensation Committee of the Board of Directors and generally vest in equal annual installments over a five-year period. A SAR may be granted alone or in conjunction with an option or other award. Shares of restricted stock, restricted stock units and performance stock units may be issued under the 2020 Plan for such consideration as is determined by the Compensation Committee of the Board of Directors. As of December 31, 2024, the Company had stock options, restricted stock and restricted and performance stock unit awards outstanding.

In May 2009, the Company’s shareholders approved the 2009 Employee Stock Purchase Plan, under which eligible employees may contribute up to 15% of their earnings toward the quarterly purchase of the Company’s common stock. The plan makes available 0.8 million shares of the Company’s common stock,

and as

of December 31, 2024, 0.8 million shares have been issued under

the plan

. Each plan period lasts three months beginning on January 1, April 1, July 1 and October 1 of each year. The purchase price for each share of stock is the lesser of 90% of the market price on the first day of the plan period or 100% of the market price on the last day of the plan period. Stock-based compensation expense related to this plan was $1 million for each of the years ended December 31, 2024, 2023 and 2022.

The Company accounts for stock-based compensation costs in accordance with the accounting standards for stock-based compensation, which require that all share-based payments to employees be recognized in the statements of operations, based on their grant date fair values. The Company recognizes the expense using the straight-line attribution method. The stock-based compensation expense recognized in the consolidated statements of operations is based on awards that ultimately are expected to vest; therefore, the amount of expense has been reduced for estimated forfeitures. Forfeitures are estimated based on historical experience. If actual results differ significantly from these estimates, stock-based compensation expense and the Company’s results of operations could be materially impacted. In addition, if the Company employs different assumptions in the application of these standards, the compensation expense that the Company records in the future periods may differ significantly from what the Company has recorded in the current period.

The consolidated statements of operations for the years ended December 31, 2024, 2023 and 2022 include the following stock-based compensation expense related to stock option awards, restricted stock awards, restricted stock unit awards, performance stock unit awards and the employee stock purchase plan (in thousands):

		2024				2023				2022
Cost of sales		$	2,587			$	2,014			$	3,498
Selling and administrative expenses			36,160				31,012				32,192
Research and development expenses			5,962				3,842				6,874
Total stock-based compensation		$	44,709			$	36,868			$	42,564

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Stock Options

In determining the fair value of the stock options, the Company makes a variety of assumptions and estimates, including volatility measures, expected yields and expected stock option lives. The fair value of each option grant was estimated on the date of grant using the Black-Scholes option pricing model. The Company uses implied volatility on its publicly traded options as the basis for its estimate of expected volatility. The Company believes that implied volatility is the most appropriate indicator of expected volatility because it is generally reflective of historical volatility and expectations of how future volatility will differ from historical volatility. The expected life assumption for grants is based on historical experience for the population of

non-qualified

stock option exercises. The risk-free interest rate is the yield currently available on U.S. Treasury

zero-coupon

issues with a remaining term approximating the expected term used as the input to the Black-Scholes

model.

The relevant data used to determine the value of the stock options granted during the twelve months ended December 31, 2024, 2023 and 2022 are as follows:

During 2024, 2023 and 2022, the total intrinsic value of the stock options exercised (i.e., the difference between the market price at exercise and the price paid by the employee to exercise the options) was $14

million,

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

$11 million and $31 million, respectively. The total cash received from the exercise of these stock options was $21 million, $18 million and $32 million for the years ended December 31, 2024, 2023 and 2022, respectively.

The aggregate intrinsic value of the outstanding stock options at December 31, 2024 was $51 million. There were 0.3 million options exercisable at December 31, 2024, 2023 and 2022. The weighted-average exercise prices of options exercisable at December 31, 2024, 2023 and 2022 were $251.63, $223.37 and $188.21, respectively. The weighted-average remaining contractual life of the exercisable outstanding stock options at December 31, 2024 was 5.3 years. The aggregate intrinsic value of stock options exercisable as of December 31, 2024 was $33 million.

At December 31, 2024, the Company had 0.6 million stock options that are vested and expected to vest. The intrinsic value, weighted-average exercise price and remaining contractual life of the vested and expected to vest stock options were $50 million, $283.20 and 6.7 years, respectively, at December 31, 2024.

The amount of compensation costs recognized for the years ended December 31, 2024, 2023 and 2022 on the stock options expected to vest were $11 million, $10 million and $8 million, respectively. As of December 31, 2024, there were $25 million of total unrecognized compensation costs related to unvested stock option awards that are expected to vest. These costs are expected to be recognized over a weighted-average period of 3.2 years.

Restricted Stock

During

each of

the years ended December 31, 2024, 2023 and 2022, the Company granted three

thousand shares of restricted stock. The weighted-average fair value per share on the grant date of the restricted stock granted in 2024, 2023 and 2022 was

$329.00, $341.04 and $363.44, respectively. The Company has recorded $1 million of compensation expense in each of the years ended December 31, 2024, 2023 and 2022 related to the restricted stock grants. As of December 31, 2024, the Company had three thousand unvested shares of restricted stock outstanding, which have been fully expensed.

Restricted Stock Units

The following table summarizes the unvested restricted stock unit award activity for the twelve months ended December 31, 2024 (in thousands, except per share data):

Restricted stock units are generally granted annually in February and vest in equal annual installments over a five-year period. The amount of compensation costs recognized for the years ended December 31, 2024, 2023 and 2022 on the restricted stock units expected to vest were $22 million, $19 million and $19 million, respectively. As of December 31, 2024, there were $60 million of total unrecognized compensation costs related to the restricted stock unit awards that are expected to vest. These costs are expected to be recognized over a weighted-average period of 3.3 years.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Performance Stock Units

The Company’s performance stock units are equity compensation awards with a market vesting condition based on the Company’s Total Shareholder Return (“TSR”) relative to the TSR of the components of the S&P Health Care Index. TSR is the change in value of a stock price over time, including the reinvestment of dividends. The vesting schedule ranges from 0% to 200% of the target shares awarded. Beginning with the grants made in 2020, the vesting conditions for performance stock units now include a performance condition based on future sales growth.

In determining the fair value of the performance stock units, the Company makes a variety of assumptions and estimates, including volatility measures, expected yields and expected terms. The fair value of each performance stock unit grant was estimated on the date of grant using the Monte Carlo simulation model. The Company uses implied volatility on its publicly traded options as the basis for its estimate of expected volatility. The Company believes that implied volatility is the most appropriate indicator of expected volatility because it is generally reflective of historical volatility and expectations of how future volatility will differ from historical volatility. The expected life assumption for grants is based on the performance period of the underlying performance stock units. The risk-free interest rate is the yield currently available on U.S. Treasury

zero-coupon

issues with a remaining term approximating the expected term used as the input to the Monte Carlo simulation model. The correlation coefficient is used to model the way in which each company in the S&P Health Care Index tends to move in relation to each other during the performance period. The relevant data used to determine the value of the performance stock units granted during the years ended December 31, 2024, 2023 and 2022 are as follows:

16 Retirement Plans

U.S. employees are eligible to participate in the Waters Employee Investment Plan, a 401(k) defined contribution plan, immediately upon hire. Employees may contribute up to 60% of eligible pay on a

pre-tax

or

post-tax

basis and the Company makes matching contributions of 100% for contributions up to 6% of eligible pay. The Company also sponsors a 401(k) Restoration Plan, which is a nonqualified defined contribution plan. Employees are 100% vested in employee and Company matching contributions for both plans. For the years ended December 31, 2024, 2023 and 2022, the Company’s matching contributions amounted to $20 million, $22 million and $21 million, respectively.

The Company also sponsors other employee benefit plans in the U.S., including a retiree healthcare plan, which provides reimbursement for medical expenses and is contributory. There are various employee benefit plans outside the United States (both defined benefit and defined contribution plans). Certain

non-U.S.

defined benefit plans

(“Non-U.S.

Pension Plans”) are included in the disclosures below, which are required under the accounting standards for retirement benefits.

The Company contributed $18 million, $18 million and $16 million in the years ended December 31, 2024, 2023 and 2022, respectively, to the

non-U.S.

plans (primarily defined contribution plans) which are currently outside of the scope of the required disclosures. The eligibility and vesting of

non-U.S. plans

are consistent with local laws and regulations.

The net periodic pension cost is made up of several components that reflect different aspects of the Company’s financial arrangements as well as the cost of benefits earned by employees. These components are determined using the projected unit credit actuarial cost method and are based on certain actuarial assumptions. The Company’s accounting policy is to reflect in the projected benefit obligation all benefit changes to which the Company is committed as of the current valuation date; use a market-related value of assets to determine pension expense; amortize increases in prior service costs on a straight-line basis over the expected future service of active participants as of the date such costs are first recognized; and amortize cumulative actuarial gains and losses in excess of 10% of the larger of the market-related value of plan assets and the projected benefit obligation over the expected future service of active participants.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Plan assets are measured at fair value using the following valuation techniques and inputs:

Level 1:		The fair value of these types of investments is based on market and observable sources from daily quoted prices on nationally recognized securities exchanges.
Level 2:		The fair value of these types of investments utilizes data points other than quoted prices in active markets that are observable either directly or indirectly.
Level 3:		These bank and insurance investment contracts are issued by well-known, highly-rated companies. The fair value disclosed represents the present value of future cash flows under the terms of the respective contracts. Significant assumptions used to determine the fair value of these contracts include the amount and timing of future cash flows and counterparty credit risk.

There have been no changes in the above valuation techniques associated with determining the value of the plans’ assets during the years ended December 31, 2024 and 2023.

The accounting standards for segment reporting establish standards for reporting information about operating segments in annual financial statements and require selected information for those segments to be presented in interim financial reports of public business enterprises. They also establish standards for related disclosures about products and services, geographic areas and major customers. The Company’s Chief Executive Officer is the CODM. The CODM evaluates the business based on our two operating segments: Waters and TA.

The Waters operating segment is primarily in the business of designing, manufacturing, selling and servicing LC and MS instruments, columns and other precision chemistry consumables that can be integrated and used along with other analytical instruments. The TA operating segment is primarily in the business of designing, manufacturing, selling and servicing thermal analysis, rheometry and calorimetry instruments. The Company’s two operating segments have similar economic characteristics; product processes; products and services; types and classes of customers; methods of distribution; and regulatory environments. Because of these similarities, the two segments have been aggregated into one reporting segment for financial statement purposes. Please refer to the consolidated financial statements for financial information regarding the one reportable segment of the Company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The Company typically experiences an increase in sales in the fourth quarter, as a result of purchasing habits for capital goods of customers that tend to exhaust their spending budgets by calendar year-end. Selling and administrative expenses are typically higher after the first quarter in each year as the Company’s annual payroll merit increases take effect.

The Company experienced significant increases in purchased intangibles amortization and interest expense beginning in the second quarter of 2023 as a result of the Wyatt acquisition.
