1 Basis of Presentation and Summary of Significant Accounting Policies

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.

The Company’s interim fiscal quarter typically ends on the thirteenth Saturday of each quarter. Since the Company’s fiscal year end is December 31, the first and fourth fiscal quarters may have more or less than thirteen complete weeks. The Company’s first fiscal quarters for 2025 and 2024 ended on March 29, 2025 and March 30, 2024, respectively.

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the instructions in Form

10-Q

and do not include all of the information and footnote disclosures required for annual financial statements prepared in accordance with generally accepted accounting principles (“U.S. GAAP”) in the United States of America. The consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany balances and transactions have been eliminated.

The preparation of consolidated financial statements in conformity with U.S. 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. Actual amounts may differ from these estimates under different assumptions or conditions.

It is management’s opinion that the accompanying interim consolidated financial statements reflect all adjustments (which are normal and recurring) that are necessary for a fair statement of the results for the interim periods. The interim consolidated financial statements should be read in conjunction with the consolidated financial statements included in the Company’s Annual Report on Form

10-K

for the year ended December 31, 2024, as filed with the U.S. Securities and Exchange Commission (“SEC”) on February 25, 2025.

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, 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 new tariff rules and regulations of the U.S. Food and Drug Administration and similar foreign regulatory authorities and agencies.

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.

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited) – (Continued)

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.

Cash and Cash Equivalents

Cash equivalents represent highly liquid investments, with original maturities of 90 days or less, while investments with longer maturities are classified as investments. 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 March 29, 2025 and December 31, 2024, $287 million out of $383 million and $275 million out of $325

million, respectively, of the Company’s total cash and cash equivalents were held by foreign subsidiaries. In addition, $

226 million out of $383 million and $226 million out of $325

million of cash and cash equivalents were held in currencies other than the U.S. dollar at March 29, 2025 and December 31, 2024, 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 three months ended March 29, 2025 and March 30, 2024 (in thousands):

		Balance at Beginning of Period				Additions				Deductions and Other				Balance at End of Period
Allowance for Credit Losses
March 29, 2025		$	14,269			$	1,036			$	(1,598	)		$	13,707
March 30, 2024		$	19,335			$	991			$	(5,461	)		$	14,865

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 March 29, 2025 and December 31, 2024. 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.

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.

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited) – (Continued)

Fair Value of Cash Equivalents, 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, 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 March 29, 2025 and December 31, 2024. 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 estimated to be $1.1 billion at both March 29, 2025 and December 31, 2024, 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 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 into interest rate swaps with an aggregate notional value of $

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

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited) – (Continued)

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 three months ended March 29, 2025, the Company did not have any cash flow hedges that were deemed ineffective.

Interest Rate Cross-Currency Swap Agreements

As of March 29, 2025, the Company had entered into interest rate cross-currency swap derivative agreements with durations up to three years with an aggregate notional value of $705 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 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 2024, the Company’s Board of Directors authorized the extension of its existing share repurchase program through January 21, 2028.

The

Company’s remaining authorization is $1.0 billion. The Company did not make any open market share repurchases in 2025 or 2024. The Company repurchased $14 million and $13 million of common stock related to the vesting of restricted stock units during the three months ended March 29, 2025 and March 30, 2024, respectively.

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 three months ended March 29, 2025 and March 30, 2024 (in thousands):

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

2024 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 $8

million of severance-related costs. The accrued restructuring expense was less than $

1 million as of March 29, 2025 and $1

million as of December 31, 2024 and included in other current liabilities on the consolidated balance sheets.

2 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.

The following is a summary of the activity of the Company’s deferred revenue and customer advances for the three months ended March 29, 2025 and March 30, 2024 (in thousands):

Total		$	1,452,384			$	891,630				7 years			$	1,414,446			$	846,540				7 years

The Company capitalized $20 million and $10 million of intangible assets in the three months ended March 29, 2025 and March 30, 2024, respectively. The gross carrying value of both the intangible assets and accumulated amortization for intangible assets increased by $18 million in the three months ended March 29, 2025 due to the effects of foreign currency translation. Amortization expense for intangible assets was $28 million and $26 million for the three months ended March 29, 2025 and March 30, 2024, respectively. Amortization expense for intangible assets is estimated to be $113 million per year for

each

of the next five years.

5 Debt

On July 12, 2024 the Company entered into a private Master Note Facility Agreement (the “Shelf Agreement”) with NYL Investors LLC, pursuant to which the Company may, at its option, authorize the issuance and sale of senior promissory notes (the “Shelf Notes”) up to an aggregate principal amount of $200 million. The purchase of any Shelf Notes is in the sole discretion of NYL. Any Shelf Notes sold or issued pursuant to the Shelf Agreement will mature no more than 15 years after the issuance date and will bear interest on the unpaid balance from the issuance date at the rates specified in the Shelf Agreement.

The Company has a five-year, $2.0 billion revolving credit facility (the “Credit Facility”) that matures in

September 2026

. As of March 29, 2025 and December 31, 2024, the Credit Facility had a total of $0.2 billion and $0.4 billion outstanding, respectively.

The interest rates applicable under the Credit Facility are, at the Company’s option, equal to either the alternate base rate (which is a rate per annum equal to the greatest of (1) the prime rate in effect on such day, (2) the Federal Reserve Bank of New York Rate on such day plus

⁄

of 1% per annum and (3) the adjusted Term SOFR rate for a

one-month

interest period as published two U.S. Government Securities Business Days prior to such day (or if such day is not a U.S. Government Securities Business Day, the immediately preceding U.S. Government Securities Business Day), plus 1% annum) or the applicable 1, 3 or 6 month adjusted Term SOFR or EURIBO rate for euro-denominated loans, in each case, plus an interest rate margin based upon the Company’s leverage ratio, which can range between 0 and 12.5 basis points for alternate base rate loans and between 80 and 112.5 basis points for Term SOFR or EURIBO rate loans. The facility fee on the Credit Facility ranges between 7.5 and 25 basis points per annum, based on the leverage ratio, of the amount of the revolving facility commitments and the outstanding term loan. The Credit Facility requires that the Company comply with an interest coverage ratio test of not less than 3.50:1 as of the end of any fiscal quarter for any period of four consecutive fiscal quarters and a leverage ratio test of not more than 3.50:1 as of the end of any fiscal quarter. In addition, the Credit Facility includes negative covenants, affirmative covenants, representations and warranties and events of default that are customary for investment grade credit facilities.

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited) – (Continued)

As of both March 29, 2025 and December 31, 2024, the Company had a total of $1.3

billion of outstanding senior unsecured notes. Interest on the fixed rate senior unsecured notes is payable semi-annually each year.

The Company may prepay all or some of the senior unsecured notes at any time in an amount not less than 10% of the aggregate principal amount outstanding. In the event of a change in control of the Company (as defined in the note purchase agreement), the Company may be required to prepay the senior unsecured notes at a price equal to 100% of the principal amount thereof, plus accrued and unpaid interest. These senior unsecured notes require that the Company comply with an interest coverage ratio test of not less than 3.50:1 for any period of four consecutive fiscal quarters and a leverage ratio test of not more than 3.50:1 as of the end of any fiscal quarter. In addition, these senior unsecured notes include customary negative covenants, affirmative covenants, representations and warranties and events of default.

The Company had the following outstanding debt at March 29, 2025 and December 31, 2024 (in thousands):

		March 29, 2025				December 31, 2024
Senior unsecured notes - Series N - 1.68%, due March 2026		$	100,000			$	—

Total long-term debt			1,356,727				1,626,488
Total debt		$	1,456,727			$	1,626,488

As of March 29, 2025 and December 31, 2024, the Company had a total amount available to borrow under the Credit Facility of $1.8 billion and $1.6 billion, respectively, after outstanding letters of credit. The weighted-average interest rates applicable to the senior unsecured notes and credit agreement borrowings collectively were 3.73% and 3.72% at March 29, 2025 and December 31, 2024, respectively. As of March 29, 2025, the Company was in compliance with all debt covenants.

The Company and its foreign subsidiaries also had available short-term lines of credit totaling $111 million at both March 29, 2025 and December 31, 2024, for the purpose of short-term borrowing and issuance of commercial guarantees. None of the Company’s foreign subsidiaries had outstanding short-term borrowings as of March 29, 2025 or December 31, 2024.

6 Income Taxes

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 March 29, 2025. The Company has a Development and Expansion Incentive in Singapore that provides a concessionary income tax rate of 5% on certain types of income for the period April 1, 2021 through March 31, 2026. The effect of applying the concessionary income tax rate rather than the statutory tax rate to income arising from qualifying activities in Singapore increased the Company’s net income for the three months ended March 29, 2025 and March 30, 2024 by $0.5 million and $2 million, respectively, and increased the Company’s net income per diluted share by $0.01 and $0.03, respectively.

The Company’s effective tax rate for the three months ended March 29, 2025 and March 30, 2024 was 15.1% and 11.0%, respectively. The income tax provision includes a $2 million and a $1

million income tax benefit related to stock-based compensation for the three months ended March 29, 2025 and March 30, 2024, respectively. The remaining differences between the effective tax rates can primarily be attributed to the impact of discrete tax benefits in the prior year and differences in the proportionate amounts of

pre-tax

income recognized in jurisdictions with different effective tax rates.

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited) – (Continued)

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 Company’s gross unrecognized tax benefits, excluding interest and penalties, at March 29, 2025 and March 30, 2024 were $18 million and $15

million, respectively. 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.

Effective in 2024, various foreign jurisdictions began implementing aspects of the guidance issued by the Organization for

Economic Co-operation and

Development related to the new Pillar Two system of global minimum tax rules. These changes in tax law did not have a material impact on the Company’s financial position, results of operations and cash flows for the three months ended March 29, 2025. The Company continues to monitor the adoption of the Pillar Two rules in additional jurisdictions.

7 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 three months ended March 30, 2024, the Company recorded $10 million of patent litigation settlement provisions and related costs. No litigation provisions were recorded by the Company during the three months ended March 29, 2025.

8 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 March 29, 2025 are $82 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 March 29, 2025. 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 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.

11 Business Segment Information

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 chief operating decision maker (“CODM”). The CODM evaluates the business based on our

two operating segments: Waters and TA.

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited) – (Continued)

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. Operations of the Wyatt business are part of the Waters operating segment. 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.
