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.

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 expanded Waters’ portfolio and increased exposure to large molecule applications. The Company financed this transaction with a combination of cash on its balance sheet and borrowings under its Credit Facility (as defined below). The Company’s financial results for the three and six months ended June 29, 2024 include the financial results of Wyatt. The Company’s financial results for the three and six months ended July 1, 2023 only include

one-and-a-half

months of the financial results of Wyatt as the closing of the acquisition occurred during the second quarter of 2023. In addition, the Company has completed the purchase price allocation for the Wyatt acquisition and there were no material changes as compared to the Company’s preliminary purchase price allocation for the Wyatt acquisition.

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 second fiscal quarters for 2024 and 2023 ended on June 29, 2024 and July 1, 2023, 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 inter-company 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, 2023, as filed with the U.S. Securities and Exchange Commission (“SEC”) on February 27, 2024.

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, Cash Equivalents and Investments

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 June 29, 2024 and December 31, 2023, $290 million out of $327 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, $228 million out of $327 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 June 29, 2024 and December 31, 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.

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 June 29, 2024 and December 31, 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.

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 June 29, 2024 and December 31, 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

estimated to be $1.1 billion and

$1.2

billion at June 29, 2024 and December 31, 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 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.

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

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 enters into interest rate swaps that will 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 six months ended June 29, 2024, the Company did not have any cash flow hedges that were deemed ineffective.

Interest Rate Cross-Currency Swap Agreements

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.

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 six months ended June 29, 2024 and July 1, 2023 (in thousands):

Restructuring

In March 2024, the Company had 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, which resulted in the Company incurring approximately

million of severance-related costs. During the six months ended June 29, 2024, the Company paid

$11

million of severance-related costs in connection with the workforce reductions that occurred in March 2024 and July 2023, with the majority of the remaining costs to be paid in the second half of 2024. The accrued restructuring expense was approximately

$4 million at June 29, 2024 and $8

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

Subsequent Event

On July 12, 2024 the Company entered into a private Master Note Facility Agreement (the “Shelf Agreement”) 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 Investors LLC. Any Shelf Notes sold or issued pursuant to the Shelf Agreement will mature no more than

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. As of July 31, 2024 the Company has

not

issued any Shelf Notes under the Shelf Agreement.

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.

6 Debt

The Company has a five-year, $2.0 billion revolving credit facility (the “Credit Facility”) that matures in September 2026. As of June 29, 2024 and December 31, 2023, the Credit Facility had a total of $0.8 billion and $1.1 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.

As of both June 29, 2024 and December 31, 2023, 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. Interest on the floating rate senior unsecured notes is payable quarterly. 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

Table of Contents

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 June 29, 2024 and December 31, 2023 (in thousands):

Total debt	$	2,006,009		$	2,355,513

As of June 29, 2024 and December 31, 2023, the Company had a total amount available to borrow under the Credit Facility of $1.2 billion and $0.9 billion, respectively, after outstanding letters of credit. The weighted-average interest rates applicable to the senior unsecured notes and credit agreement borrowings collectively were 4.44% and 4.69% at June 29, 2024 and December 31, 2023, respectively. As of June 29, 2024, 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 and $114 million at June 29, 2024 and December 31, 2023, respectively, 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 June 29, 2024 or December 31, 2023.

7 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 June 29, 2024. 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 six months ended June 29, 2024 and July 1, 2023 by $5 million and $7 million, respectively, and increased the Company’s net income per diluted share by $0.09 and $0.11, respectively.

The Company’s effective tax rate for the three months ended June 29, 2024 and July 1, 2023 was 15.7% and 16.5%,

respectively. The decrease between the effective tax rates can be primarily attributed to a higher tax benefit related to stock-based compensation in the three months ended June 29, 2024, with the remaining difference due to the proportionate amounts of pre-tax income recognized in jurisdictions with different effective tax rates.

The Company’s effective tax rate for the six months ended June 29, 2024 and July 1, 2023 was 13.8% and 15.6%, respectively. The decrease between the effective tax rates can primarily be attributed to a higher tax benefit related to stock-based compensation in 2024, the impact of discrete tax benefits in the current year and differences in the proportionate amounts of

pre-tax

income recognized in jurisdictions with different effective tax rates.

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 June 29, 2024 and July 1, 2023 were $15 million and $30 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, 2018. 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 and six months ended June 29, 2024. The Company continues to monitor the adoption of the Pillar Two rules in additional jurisdictions.

8 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 six months ended June 29, 2024, the Company recorded and paid

$10

million of patent litigation settlement and related costs.

9 Other Commitments and Contingencies

The Company licenses certain technology and software from third parties in the course of ordinary business. Future minimum license fees payable under existing license agreements as of June 29, 2024 are immaterial for the years ended December 31, 2024 and thereafter.

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.

12 Business Segment Information

The Company’s business activities, for which discrete financial information is available, are regularly reviewed and evaluated by the chief operating decision maker. As a result of this evaluation, the Company determined that it has 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. 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.

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

Business Overview

The Company has two operating segments: Waters^TM and TA^TM. Waters products and services primarily consist of high-performance liquid chromatography (“HPLC”), ultra-performance liquid chromatography (“UPLC^TM” and, together with HPLC, referred to as “LC”), mass spectrometry (“MS”), light scattering and field-flow fractionation instruments (Wyatt), and precision chemistry consumable products and related services. TA products and services primarily consist of thermal analysis, rheometry and calorimetry instrument systems and service sales. The Company’s products are used by pharmaceutical, biochemical, industrial, nutritional safety, environmental, academic and government customers. These customers use the Company’s products to detect, identify, monitor and measure the chemical, physical and biological composition of materials and to predict the suitability and stability of fine chemicals, pharmaceuticals, water, polymers, metals and viscous liquids in various industrial, consumer goods and healthcare products.

Wyatt Acquisition

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 expanded Waters’ portfolio and increase 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 three and six months ended June 29, 2024 include the financial results of Wyatt. The Company’s financial results for the three and six months ended July 1, 2023 only include one-and-a-half months of Wyatt’s financial results as the closing of the acquisition occurred during the second quarter of 2023.

The Company’s net sales decreased 4% in the second quarter of 2024, as compared to the second quarter of 2023, with foreign currency translation decreasing total sales growth by 2%. For the first half of 2024, the Company’s net sales decreased 6% with the effect of foreign currency translation decreasing sales growth by 1% as compared to the first half of 2023. In both the second quarter and first half of 2024, the Company’s net sales were negatively impacted by our customers delaying the purchase of our instrument systems as they remained cautious with their capital spending during the first half of 2024. The Wyatt acquisition increased sales growth by 2% and 3% for the second quarter and first half of 2024, respectively. In addition, the Company’s first half of 2024 had one less calendar day than the first half of 2023. At current foreign currency exchange rates, the Company expects that foreign currency translation will have a negative impact on sales for the remainder of 2024.

Instrument system sales decreased 14% and 17% for the second quarter and first half of 2024, respectively, primarily driven by weaker customer demand across all major regions. The decline in instrument system sales was broad-based across all of our instrument systems and was led by our mass spectrometry instrument systems, which are higher priced instruments that are significantly impacted by the timing and level of funding our academic and government customers receive. The Wyatt acquisition increased instrument system sales growth by 4% for both the second quarter and first half of 2024. Foreign currency translation decreased instrument system sales growth by 1% in the second quarter of 2024 but had no impact in the first half of 2024.

Recurring revenues (combined sales of precision chemistry consumables and services) increased 4% for both the second quarter and first half of 2024, with foreign currency translation decreasing sales growth by 2% in both the second quarter and first half of 2024. Service revenues increased 4% and 5% for the second quarter and first half of 2024, respectively. Wyatt contributed 1% and 2% to service revenue growth for the second quarter and first half of 2024, respectively. Chemistry sales growth increased 4% and 2% for the second quarter and first half of 2024, respectively, and was impacted by the lower customer demand in China for our products.

Operating income decreased for the second quarter and first half of 2024, primarily due to lower sales volume as well as the Wyatt acquisition-related retention expenses and purchased intangibles amortization, which collectively decreased operating income by 8% and 10%, respectively. In addition, operating income for the first half of 2024 was impacted by first quarter of 2024 severance-related costs associated with a workforce reduction primarily in China and a litigation settlement, which collectively decreased operating income by 5%. These costs were partially offset by cost savings from recent workforce reductions and the absence of transaction costs related to the Wyatt acquisition. The negative effect of foreign currency translation lowered operating income by approximately $9 million and $16 million for the second quarter and first half of 2024, respectively.

The Company generated $317 million and $215 million of net cash from operating activities in the first half of 2024 and 2023, respectively, with the $102 million increase being attributable to lower annual incentive bonus payments and an improvement in working capital in the current year. Net cash used in investing activities included capital expenditures related to property, plant, equipment and software capitalization of $65 million and $81 million in the first half of 2024 and 2023, respectively.

Geographically, the decline in the Company’s sales in the second quarter and first half of 2024 was broad-based across most major regions, led by China and Japan, while sales in India increased 11% and 13% in the second quarter and first half of 2024, respectively. The broad-based decline in sales can be attributed to the lower demand for our instrument systems as customers delayed the purchase of these products. Excluding China sales, the Company’s sales declined 3% for both the second quarter and first half of 2024. Foreign currency translation decreased sales growth in Asia by 5% and 4% for the second quarter and first half of 2024 respectively. Foreign currency translation decreased sales growth in Japan by 12% and 9% for the second quarter and first half of 2024, respectively.

During the second quarter of 2024, sales to pharmaceutical customers decreased 3%, as growth in India was offset by weakness across most other major regions, with foreign currency translation decreasing pharmaceutical sales growth by 2% and Wyatt contributing 3% to the Company’s pharmaceutical sales growth. Combined sales to industrial customers, which include material characterization, food, environmental and fine chemical markets, decreased 4% in the second quarter of 2024, with foreign currency translation decreasing sales growth by 1% and Wyatt contributing 1% to industrial sales growth. Combined sales to academic and government customers decreased 15% in the second quarter of 2024, with foreign currency translation decreasing sales growth by 1% and Wyatt contributing 2% to the Company’s academic and government sales growth.

During the first half of 2024, sales to pharmaceutical customers decreased 3%, primarily driven by weakness in customer demand in China, with foreign currency translation decreasing pharmaceutical sales growth by 1% and Wyatt contributing 4%. Combined sales to industrial customers decreased 5%, with foreign currency translation decreasing sales growth by 1% and Wyatt contributing 1% to industrial sales growth. Sales to our academic and government customers are highly dependent on when institutions receive funding to purchase our instrument systems and, as such, sales can vary significantly from period to period. Combined sales to academic and government customers decreased 20%, with foreign currency translation having minimal impact on sales growth and Wyatt contributing 3% to the Company’s academic and government sales growth. This overall decline in sales of 20% to our academic and government customers in the first half of 2024 compares to a 30% increase in academic and government sales in the first half of 2023, which represents a two-year compound annual growth rate of 2%.

The contribution from Wyatt increased Waters products and service sales growth by 3% for both the second quarter and first half of 2024. Waters instrument system sales decreased by 16% and 19% for the second quarter and first half of 2024, respectively, due to weaker customer demand across most major regions. Wyatt’s instrument system sales contributed 5% to Waters instrument system sales growth for both the second quarter and first half of 2024. The increase in Waters chemistry consumables sales was primarily due to the continued demand in most major geographies, driven by the uptake in columns and application-specific testing kits to pharmaceutical customers, partially offset by the negative impact from foreign currency translation which decreased sales growth by 1% in both the second quarter and first half of 2024. Waters service sales increased 4% and 5% for the second quarter and first half of 2024, respectively, due to higher service demand billing in all regions except for China, partially offset by the negative impact from foreign currency translation which decreased service sales growth by 2% and 1% in the second quarter and first half of 2024, respectively. Wyatt service revenues added 1% and 2% to Waters service revenue growth for the second quarter and first half of 2024, respectively.

TA Product and Services Net Sales

Net sales for TA products and services were as follows for the three and six months ended June 29, 2024 and July 1, 2023 (dollars in thousands):


	Three Months Ended
	June 29, 2024		% of Total			July 1, 2023		% of Total			% change
TA instrument systems	$	58,831		68	%	$	62,067		71	%		(5	%)

Total TA net sales	$	85,968		100	%	$	87,341		100	%		(2	%)


	Six Months Ended
	June 29, 2024		% of Total			July 1, 2023		% of Total			% change
TA instrument systems	$	109,516		68	%	$	120,798		71	%		(9	%)
TA service		51,392		32	%		49,142		29	%		5	%

Total TA net sales	$	160,908		100	%	$	169,940		100	%		(5	%)

TA sales declined 2% and 5% for the second quarter and first half of 2024, respectively, due to lower customer demand for TA instrument systems across most major regions. Foreign currency translation decreased sales by 2% for both the second quarter and first half of 2024.

Cost of Sales

Cost of sales decreased by 4% and 6% in the second quarter and first half of 2024, respectively. The decrease in these periods is primarily due to lower sales volume and changes in sales mix. Cost of sales is affected by many factors, including, but not limited to, foreign currency translation, product mix, product costs of instrument systems and amortization of software platforms. At current foreign currency exchange rates, the Company expects foreign currency translation to decrease gross profit during 2024.

Selling and Administrative Expenses

Selling and administrative expenses decreased 7% and 6% in the second quarter and first half of 2024, respectively. The decrease in these periods is primarily due to the decline in salary expense resulting from lower headcount from the recent reductions in workforce and a decrease in the Wyatt acquisition diligence and integration costs incurred in the second quarter and first half of 2023, which declined $4 million and $12 million, respectively. These decreases were partially offset by the increases of $2 million and $9 million related to Wyatt acquisition-related retention expenses in the second quarter and first half of 2024, respectively. The effect of foreign currency translation increased selling and administrative expenses by 1% for both the second quarter and first half of 2024.

As a percentage of net sales, selling and administrative expenses were 24.5% and 25.9% for the second quarter and first half of 2024, respectively, and 25.2% and 25.9% for the second quarter and first half of 2023, respectively.

Research and Development Expenses

Research and development expenses increased 1% and 2% in the second quarter and first half of 2024, respectively. The increase in these periods was driven by costs associated with the development of new product and technology initiatives. The impact of foreign currency exchange increased expenses by 1% for both the second quarter and first half of 2024.

Purchased Intangibles Amortization

The increase in purchased intangibles amortization of $5 million and $15 million in the second quarter and first half of 2024, respectively, is primarily due to the Wyatt acquisition intangible assets.

Litigation Provisions

The Company incurred a $10 million patent litigation settlement in the first half of 2024.

Interest Expense, net

The increase in interest expense for both the second quarter and first half of 2024 can be primarily attributed to the additional borrowings by the Company to fund the Wyatt acquisition.

Provision for 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 June 29, 2024. 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 from qualifying activities in Singapore increased the Company’s net income by $5 million and $7 million and increased the Company’s net income per diluted share by $0.09 and $0.11 for the second quarter of 2024 and 2023, respectively.

The Company’s effective tax rate for the second quarter of 2024 and 2023 was 15.7% and 16.5%, respectively. The decrease in the effective tax rate can be primarily attributed to a higher tax benefit related to stock-based compensation in the second quarter of 2024, with the remaining difference due to the proportionate amounts of pre-tax income recognized in jurisdictions with different effective tax rates.

The Company’s effective tax rate for the first half of 2024 and 2023 was 13.8% and 15.6%, respectively. The decrease in the effective tax rate can be attributed to a higher tax benefit related to stock-based compensation in 2024, the impact of discrete tax benefits in the current year and differences in the proportionate amounts of pre-tax income recognized in jurisdictions with different effective tax rates.

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 second quarter and first half of 2024. The Company continues to monitor the adoption of the Pillar Two rules in additional jurisdictions.

Cash Flow from Operating Activities

Net cash provided by operating activities was $317 million and $215 million during the first half of 2024 and 2023, respectively. The increase in 2024 operating cash flow was primarily a result of higher cash collections, lower inventory levels and lower incentive bonus payments, partially offset by lower net income. The changes within net cash provided by operating activities include the following significant changes in the sources and uses of net cash provided by operating activities, aside from the changes in net income:

•

The changes in accounts receivable were primarily attributable to the timing of payments made by customers and timing of sales. Days sales outstanding was 78 days at June 29, 2024 and 85 days at July 1, 2023.

•

The change in inventory can primarily be attributed to the reduction in our production plan as a result of the decline in sales.

•

Net cash provided from deferred revenue and customer advances results from annual increases in new service contracts as a higher installed base of customers renew annual service contracts.

•

A decrease in income tax payments of $32 million as compared to the prior year and the payment of $20 million in Wyatt acquisition-related retention payments.

•

Other changes were attributable to variation in the timing of various provisions, expenditures, prepaid income taxes and accruals in other current assets, other assets and other liabilities.

Cash Flow from Investing Activities

Net cash used in investing activities totaled $66 million and $1.4 billion in the first half of 2024 and 2023, respectively. Additions to fixed assets and capitalized software were $65 million and $81 million in the first half of 2024 and 2023, respectively.

During the first half of 2024 and 2023, the Company purchased $2 million and $1 million of investments, respectively, while $2 million and $1 million of investments matured, respectively, and were used for financing activities described below.

On May 16, 2023, the Company completed the acquisition of 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 will expand Waters’ portfolio and increase exposure to large molecule applications.

Cash Flow from Financing Activities

The Company has a credit agreement with an aggregate borrowing capacity of $2.0 billion. As of June 29, 2024, the Company had a total of $2.0 billion in outstanding debt, which consisted of $1.3 billion in outstanding senior unsecured notes and $750 million borrowed under its credit agreement. The Company’s net debt borrowings decreased by $350 million and increased by $1.1 billion during the first half of 2024 and 2023, respectively, with the prior year increase primarily being due to the funding of the Wyatt acquisition.

As of June 29, 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. As a result of entering into these agreements, the Company lowered net interest expense by approximately $5 million during both the first half of 2024 and 2023. The Company anticipates that these swap agreements will lower net interest expense by approximately $10 million in 2024.

In December 2023, the Company’s Board of Directors authorized the extension of its existing share repurchase program through January 21, 2025. The Company’s remaining authorization is $1.0 billion. During the first half of 2023, the Company repurchased $58 million of the Company’s outstanding common stock under the Company’s share repurchase program. In addition, the Company repurchased $13 million and $11 million of common stock related to the vesting of restricted stock units during the first half of 2024 and 2023, respectively. The Company believes that it has the financial flexibility to fund these share repurchases, as well as to invest in research, technology and business acquisitions, given current cash levels and debt borrowing capacity.

The Company received $22 million and $9 million of proceeds from the exercise of stock options and the purchase of shares pursuant to the Company’s employee stock purchase plan during the first half of 2024 and 2023, respectively.

The Company had cash, cash equivalents and investments of $327 million as of June 29, 2024. The majority of the Company’s cash and cash equivalents are generated from foreign operations, with $290 million held by foreign subsidiaries at June 29, 2024, of which $228 million was held in currencies other than U.S. dollars.

On July 12, 2024, the Company entered into a Master Note Facility Agreement pursuant to which the Company may, at its option, authorize the issuance and sale of senior promissory notes up to an aggregate principal amount of $200 million with a maturity date not to exceed 15 years after the issuance date.

Contractual Obligations, Commercial Commitments, Contingent Liabilities and Dividends

A summary of the Company’s contractual obligations and commercial commitments is included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on February 27, 2024. The Company reviewed its contractual obligations and commercial commitments as of June 29, 2024 and determined that there were no material changes outside the ordinary course of business from the information set forth in the Annual Report on Form 10-K.

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 that it has meritorious arguments in its current litigation matters and that any outcome, either individually or in the aggregate, will not be material to the Company’s financial position or results of operations.

During fiscal year 2024, the Company expects to contribute a total of approximately $3 million to $6 million to its defined benefit plans.

The Company has not paid any dividends and has no plans, at this time, to pay any dividends in the future.

Critical Accounting Policies and Estimates

In the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on February 27, 2024, the Company’s most critical accounting policies and estimates upon which its financial status depends were identified as those relating to revenue recognition, valuation of long-lived assets, intangible assets and goodwill, income taxes, uncertain tax positions and business combinations and asset acquisitions. The Company reviewed its policies and determined that those policies remain the Company’s most critical accounting policies for the six months ended June 29, 2024. The Company did not make any changes in those policies during the six months ended June 29, 2024.

Certain of these and other factors are discussed under the heading “Risk Factors” under Part I, Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on February 27, 2024. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements, whether because of these factors or for other reasons. All forward-looking statements speak only as of the date of this Quarterly Report on Form 10-Q and are expressly qualified in their entirety by the cautionary statements included in this report. Except as required by law, the Company does not assume any obligation to update any forward-looking statements.

Item 3: Quantitative and Qualitative Disclosures About Market Risk

The Company is exposed to the risk of interest rate fluctuations from the investments of cash generated from operations. Investments with maturities greater than 90 days are classified as investments and are held primarily in U.S. dollar-denominated treasury bills and commercial paper, bank deposits and corporate debt securities. As of June 29, 2024, the Company estimates that a hypothetical adverse change of 100 basis points across all maturities would not have a material effect on the fair market value of its portfolio.

The Company is also exposed to the risk of exchange rate fluctuations. 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 June 29, 2024 and December 31, 2023, $290 million out of $327 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, $228 million out of $327 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 June 29, 2024 and December 31, 2023, respectively. As of June 29, 2024, the Company had no holdings in auction rate securities or commercial paper issued by structured investment vehicles.

Assuming a hypothetical adverse change of 10% in year-end exchange rates (a strengthening of the U.S. dollar), the fair market value of the Company’s cash, cash equivalents and investments held in currencies other than the U.S. dollar as of June 29, 2024 would decrease by approximately $23 million, of which the majority would be recorded to foreign currency translation in other comprehensive income within stockholders’ equity.

There have been no other material changes in the Company’s market risk during the six months ended June 29, 2024. For information regarding the Company’s market risk, refer to Item 7A of Part II of the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on February 27, 2024.

Item 4: Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Company’s chief executive officer and chief financial officer (principal executive officer and principal financial officer), with the participation of management, evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on this evaluation, the Company’s chief executive officer and chief financial officer concluded that the Company’s disclosure controls and procedures were effective as of June 29, 2024 (1) to ensure that information required to be disclosed by the Company, including its consolidated subsidiaries, in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its chief executive officer and chief financial officer, to allow timely decisions regarding the required disclosure and (2) to provide reasonable assurance that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Changes in Internal Control Over Financial Reporting

No change was identified in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended June 29, 2024 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Part II: Other Information

Item 1: Legal Proceedings

There have been no material changes in the Company’s legal proceedings during the six months ended June 29, 2024 as described in Item 3 of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on February 27, 2024, other than the $10 million patent litigation settlement and related costs recorded and paid in the six months ended June 29, 2024.

Item 1A: Risk Factors

Information regarding risk factors of the Company is set forth under the heading “Risk Factors” under Part I, Item 1A in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on February 27, 2024. The Company reviewed its risk factors as of June 29, 2024 and determined that there were no material changes from the ones set forth in the Form 10-K. Note, however, the discussion of certain factors under the subheading “Special Note Regarding Forward-Looking Statements” in Part I, Item 2 of this Quarterly Report on Form 10-Q. These risks are not the only ones facing the Company. Additional risks and uncertainties not currently known to the Company or that the Company currently deems to be immaterial may have a material adverse effect on the Company’s business, financial condition and operating results.

Item 2: Unregistered Sales of Equity Securities and Use of Proceeds

Purchases of Equity Securities by the Issuer

During the three months ended June 29, 2024, the Company purchased 202, 367 and 162 shares at a cost of $68 thousand, $125 thousand and $52 thousand with average prices paid of $335.94, $341.33 and $320.54 during fiscal April, May and June, respectively, of equity securities registered by the Company under the Exchange Act.

In January 2019, the Company’s Board of Directors authorized the Company to repurchase up to $4 billion of its outstanding common stock in open market or private transactions over a two-year period. This program replaced the remaining amounts available under the pre-existing authorization. In December 2020, the Company’s Board of Directors authorized the extension of the share repurchase program through January 21, 2023. In December 2022, the Company’s Board of Directors amended and extended this repurchase program’s term by one year such that it expired on January 21, 2024 and increased the total authorization level to $4.8 billion, an increase of $750 million. In December 2023, the Company’s Board of Directors authorized the extension of the share repurchase program through January 21, 2025. As of June 29, 2024, the Company had repurchased an aggregate of 15.2 million shares at a cost of $3.8 billion under the January 2019 repurchase program and had a total of $1.0 billion authorized for future repurchases. The size and timing of these purchases, if any, will depend on our stock price and market and business conditions, as well as other factors.

Dear Robert,

On behalf of Waters Technologies Corporation (the “Company”), I am pleased to extend this offer of employment to you. This letter (the “Agreement”) confirms the terms and conditions of your employment with the Company and supersedes all prior agreements and understandings between the parties with respect to the subject matter hereof, and such agreements and understandings are expressly terminated and of no further force or effect.

1. Position and Duties.

(a) We anticipate that you will commence your employment on June 24, 2024, or such other date mutually agreed upon between you and the Company (the actual date of such commencement, the “Start Date”). As of the Start Date you will be employed by the Company, on a full-time basis, as Senior Vice President Waters Division and report to the President and Chief Executive Officer of the Company. In addition to serving as the Company’s Senior Vice President Waters Division, you may be asked from time to time to serve as a director or officer of one or more of the Company’s Affiliates, in each case, without further compensation. For purposes of this Agreement, “Affiliates” means all persons and entities directly or indirectly controlling, controlled by or under common control with the Company.

(b) You agree to perform the duties of your position and such other duties and responsibilities as may be reasonably assigned to you from time to time. You also agree that, while employed by the Company, you will devote your full business time and your best efforts, business judgment, skill and knowledge exclusively to the advancement of the business interests of the Company and its Affiliates and to the discharge of your duties and responsibilities for them. Notwithstanding the foregoing, you shall be permitted to engage in civic, charitable and philanthropic activities, and to manage your passive personal investments and, with the consent of the Board of Directors of the Company (the “Board”) or a committee thereof, to serve on the board of directors of for-profit and not-for-profit companies or organizations; provided that, in the aggregate, such activities do not interfere or conflict with your duties to the Company.

(c) Further, you agree that, while employed by the Company, you will comply with all written Company policies, practices and procedures and all codes of ethics or business conduct policies applicable to your position, as in effect from time to time, including, without limitation, the Waters Corporation Mandatory Clawback Policy.

2. Compensation and Benefits. During the period of your employment by the Company, as compensation for all services performed by you for the Company and its Affiliates, the Company will provide you the following pay and benefits:

(a) Base Salary. The Company shall pay you an annualized base salary equal to $580,000, payable subject to standard federal and state payroll withholding requirements in accordance with the regular payroll practices of the Company (which is currently a semi-monthly pay cycle) and subject to annual review by the Compensation Committee of the Board (the “Compensation Committee”) (such base salary, as in effect from time to time, “Base Salary”).

(b) Annual Incentive Compensation. For each fiscal year completed during your employment with the Company, including the 2024 fiscal year, you will be eligible to earn annual incentive compensation under the Company’s Annual Incentive Plan, or such other bonus plan in which Company executives participate generally (such plan, as in effect from time to time, the “AIP”). Your target annual incentive compensation opportunity under the AIP will be 75% of your Base Salary. The actual amount payable in respect of your annual incentive compensation opportunity, if any, for any fiscal year will be determined by the Compensation Committee based on the achievement of performance goals previously established by the Compensation Committee in its discretion and your remaining employed by the Company on the date that such annual incentive compensation is paid. Any annual incentive compensation due hereunder will be paid in accordance with the terms of the AIP and on or before March 15^th of the year following the fiscal year with respect to which the annual incentive compensation is earned, subject to your remaining employed by the Company on the date that such annual incentive compensation is paid. Notwithstanding the foregoing, if your Start Date begins on or before September 30th, the actual amount payable will be prorated based upon your Start Date, and if your Start Date is after September 30th, you will only be eligible to participate in the AIP at the beginning of the following calendar year.

(c) Initial Annual Equity Grant. On the Start Date, you will be granted equity-based awards under the Company’s 2020 Equity Incentive Plan (as in effect from time to time, the “EIP”) with respect to shares of the Company’s common stock, par value $0.01 per share (“Common Stock”), having a total target grant date value of approximately $1,300,000 (collectively, the “Initial Awards”). It is expected that the Initial Awards will be granted 50% in the form of non-qualified stock options and 50% in the form of time-based restricted stock units. The Initial Awards will be subject to the EIP and the applicable award agreements evidencing such awards. You agree to execute the Company’s applicable forms of grant notice and award agreement to finalize our agreement as to the Initial Awards.

(d) Future Annual Equity Grants. You will be eligible for future annual equity grants under the EIP at such times and in such form as determined by the Compensation Committee in its discretion.

(e) Sign-On Bonus. On or as soon as practicable following the Start Date, subject to your continued employment with the Company through the payment date, you will be paid a lump sum cash bonus of $200,000 (the “Sign-On Bonus”). Notwithstanding the foregoing, in the event that your employment with the Company is terminated by the Company for Cause or by you without Good Reason (each as defined below) (i) prior to the one (1)-year anniversary of the Start Date, you will be required to repay to the Company one-hundred percent (100%) of the Sign-On Bonus within thirty (30) days following such date of termination; or (ii) within the period commencing on the one (1)-year anniversary of the Start Date and ending on the two (2)-year anniversary of the Start Date, you will be required to repay to the Company fifty percent (50%) of the Sign-On Bonus within thirty (30) days following such date of termination.

(f) Participation in Employee Benefit Plans. You will be entitled to participate in all applicable employee benefit plans or programs from time to time in effect for executives of the Company generally, except to the extent such plans are duplicative of benefits otherwise provided to you under this Agreement. Your participation will be subject to the terms of the applicable plan or program documents and generally applicable Company policies, as the same may be in effect from time to time, and any other restrictions or limitations imposed by law. The Company reserves the right to change, alter, or terminate any benefit plan in its sole discretion.

(g) Vacation. You will be entitled to five weeks’ vacation per year during your employment, in addition to holidays observed by the Company. Vacation may be taken at such times and intervals as you shall determine, subject to the business needs of the Company. Vacation shall otherwise be subject to the policies of the Company, as in effect from time to time.

(h) Business Expenses. The Company will pay or reimburse you for all reasonable business expenses incurred or paid by you in the performance of your duties and responsibilities for the Company, subject to any restrictions on such expenses set by the Company and to such reasonable substantiation and documentation as may be specified from time to time. Your right to payment or reimbursement for expenses hereunder shall be subject to the following additional rules: (i) the amount of expenses eligible for payment or reimbursement during any calendar year shall not affect the expenses eligible for payment or reimbursement in any other calendar year; (ii) payment or reimbursement shall be made not later than December 31 of the calendar year following the calendar year in which the expense or payment was incurred; and (iii) the right to payment or reimbursement is not subject to liquidation or exchange for any other benefit.

(i) Relocation. You will be required to relocate to the Milford, MA area or another approved Company location at such time as mutually agreed between you and the CEO or the Board. You will be entitled to relocation assistance pursuant to the Company’s executive relocation program, as may be amended from time to time.

3. Confidential Information, Inventions Assignment, and Restricted Activities. As a condition of your employment with the Company as contemplated herein, you agree to execute and abide by the confidential information, inventions assignment and restrictive covenants agreement (“Confidentiality, IA, and Restrictive Covenants Agreement”) enclosed herein, which may be amended by us from time to time without regard to this Agreement. The Confidentiality, IA, and Restrictive Covenants Agreement contains provisions that are intended by us to survive and do survive termination of this Agreement.

4. Employment At-Will. This Agreement is not intended to constitute a contract of employment for a definite term. Your employment with the Company will be at-will. This means that if you accept this offer both you and the Company will retain the right to terminate our employment relationship at any time, subject to the terms of this Agreement.

5. Termination of Employment.

(a) Final Compensation. In the event of termination of your employment with the Company for any reason or no reason, the Company shall pay you (i) your Base Salary for the final payroll period of your employment, through the date your employment terminates; (ii) any vacation time earned but not used as of the date your employment terminates, subject to applicable law and the applicable policies of the Company, as in effect from time to time; (iii) reimbursement for business expenses incurred by you but not yet paid to you as of the date your employment terminates; provided that you submit all expenses and supporting documentation required within thirty (30) days of the date your employment terminates, and provided further that such expenses are reimbursable under Company policies as then in effect; and (iv) any amounts or benefits due to you under any benefit plan, program or arrangement of the Company in accordance with the terms of such plan, program or arrangement (all of the foregoing, “Final Compensation”). The Final Compensation shall be paid within thirty (30) days following the termination of your employment, or earlier if required by applicable law.

(b) Severance. In the event of a termination of your employment with the Company by the Company without Cause or by you for Good Reason, subject to the Change of Control Agreement (as defined below), the Company will pay you, in addition to Final Compensation, (i) salary continuation in an amount equal to your annual Base Salary (the “Severance Payments”); and (ii) in a lump sum, an amount equal to the amount the Company would have paid in premiums under the life, accident, health and dental insurance plans of the Company in which you and your dependents were participating immediately prior to the termination of your employment for the twelve (12)-month period following the date of termination of your employment, with such lump sum amount payable pursuant to this Section 5(b) to be determined based on the premium rates in effect at the time of the termination of your employment (the “Health Payment”).

(c) Conditions to and Timing of Severance. Notwithstanding any other provision of this Agreement to the contrary, the Severance Payments and the Health Payment shall be paid or provided to you only if you enter into a general release of claims in the form provided by the Company that contains non-competition, non-solicitation and other restrictive covenants substantially similar to those contained in this Agreement (the “Release”) within a period of time not to exceed forty-five (45) days from the date of termination of your employment, and you do not revoke the Release. Any Severance Payments to which you are entitled will be provided in the form of salary continuation, payable in accordance with the normal payroll practices of the Company. The Health Payment will be paid in a lump sum. Except as provided in Section 7 of this Agreement, the Severance Payments will commence and the Health Payment will be made, in each case, on the Company’s next regular payday following the date the Release becomes effective, but

no later than the date that is sixty (60) days following the date your employment terminates. Notwithstanding the foregoing, if the date your employment terminates occurs in one taxable year and the date that is sixty (60) days following such termination date occurs in a second taxable year, to the extent required by Section 409A of the Internal Revenue Code, as amended and the regulations and guidance promulgated thereunder (collectively, “Section 409A”), such payment shall not be made prior to the first day of the second taxable year. For the avoidance of doubt, if you do not execute the Release within the period specified in this Section 5(c) or if you revoke the executed Release within the time period permitted by law, you will not be entitled to any payments or benefits set forth in this Section, and neither the Company nor any of its Affiliates will have any further obligations to you under this Agreement or otherwise. Further the obligation of the Company to make payments to you under this Section 5(c) and your right to retain the same, are conditioned upon your continued compliance with Section 3 of this Agreement.

(d) Definitions. For purposes of this Agreement,

(i) “Cause” shall mean: (A) your indictment for, or the pleading of guilty or nolo contendere to, any felony or any crime involving moral turpitude; (B) your gross negligence, breach of fiduciary duty, breach of any non-competition, non-solicitation or developments agreement or covenant in favor of the Company or material breach of any confidentiality agreement or covenant in favor of the Company; (C) you shall have willfully and continually failed to substantially perform your duties with the Company after a written demand for substantial performance is delivered by the Company, which demand specifically identifies the manner in which the Company believes that you have not substantially performed your duties pursuant to the disciplinary procedures of the Company, and such failure of substantial performance shall have continued for a period of thirty (30) days after such written demand; (D) you have been chronically absent from work (excluding vacations, illnesses or leaves of absences); (E) the commission by you of an act of fraud, embezzlement or misappropriation against the Company; (F) you shall have refused, after explicit notice, to obey any lawful resolution or direction by the Board or a committee thereof or the President and Chief Executive Officer of the Company, in either case, which is consistent with your duties as an officer of the Company; (G) a breach by you of the Confidentiality, IA, and Restrictive Covenants Agreement, or of any written Company policy, practice or procedure relating to the protection of Confidential Information (as defined in the Confidentiality, IA, and Restrictive Covenants Agreement) or to the non-use or disclosure to or on behalf of the Company of confidential or proprietary information of a third party; or (H) a material breach by you of this Agreement, which breach (if curable) has remained uncured for a period of thirty (30) days following the Company’s delivery of written notice to you specifying the manner in which the Agreement has been materially breached.

(ii) “Good Reason” shall mean (if occurring without your consent): (A) a material diminution in your duties or responsibilities; (B) a material reduction in your Base Salary (except for salary reductions similarly affecting all senior executives of the Company); (C) a material change in your place of business (provided, however, that travel for business purposes shall not be considered a change in your place of business for the purpose of this clause (C)); or (D) a material breach by the Company of this Agreement; provided, that the occurrence of any of the foregoing events shall not constitute Good Reason unless (x) (1) you provide written notice of the event to the Company within ninety (90) days after it first existed; (2) the Company fails to remedy the

condition within thirty (30) days after the notice; and (3) you actually terminate employment within thirty (30) days after the expiration of the Company’s cure period or (y) if the event follows an event or action by you that would constitute Cause (as defined herein) for termination.

6. Termination of Employment in Connection with a Change of Control. On or as soon as reasonably practicable following the Start Date, you will be offered the opportunity to enter into a Change of Control/Severance Agreement (the “Change of Control Agreement”) with the Company. The Change of Control Agreement will be provided to you under separate cover. For the avoidance of doubt, any rights you may have to payments or benefits upon a termination of your employment in connection with a change of control of the Company will be as set forth in the Change of Control Agreement, and will be subject to your execution of the Change of Control Agreement.

7. Timing of Payments and Section 409A.

(a) Notwithstanding anything to the contrary in this Agreement, if at the time your employment terminates, you are a “specified employee,” as defined below, any and all amounts payable under this Agreement or the Change of Control Agreement, as applicable, on account of such separation from service that would (but for this provision) be payable within six (6) months following the date of termination, shall instead be paid on the next business day following the expiration of such six (6)-month period or, if earlier, upon your death, except (A) to the extent of amounts that do not constitute a deferral of compensation within the meaning of Treasury regulation Section 1.409A-1(b) (including without limitation by reason of the safe harbor set forth in Section 1.409A-1(b)(9)(iii), as determined by the Company in its reasonable good faith discretion); (B) benefits which qualify as excepted welfare benefits pursuant to Treasury regulation Section 1.409A-1(a)(5); or (C) other amounts or benefits that are not subject to the requirements of Section 409A.

(b) For purposes of this Agreement, all references to “termination of employment” and correlative phrases shall be construed to require a “separation from service” (as defined in Section 1.409A-1(h) of the Treasury regulations after giving effect to the presumptions contained therein), and the term “specified employee” means an individual determined by the Company to be a specified employee under Treasury regulation Section 1.409A-1(i).

(c) Each payment made under this Agreement shall be treated as a separate payment and the right to a series of installment payments under this Agreement is to be treated as a right to a series of separate payments.

(d) It is the intent of the parties hereto that the payments and benefits under this Agreement be exempt from or comply with Section 409A and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted in accordance therewith. In no event, however, shall the Company or any of its Affiliates have any liability relating to the failure or alleged failure of any payment or benefit under this Agreement to comply with, or be exempt from, the requirements of Section 409A.

8. Conflicting Agreements. You hereby represent and warrant that your signing of this Agreement and the performance of your obligations under it will not breach or be in conflict with any other agreement to which you are a party or are bound, and that you are not now subject to any covenants against competition or similar covenants or any court order that could affect the performance of your obligations under this Agreement. You agree that you will not disclose to or use on behalf of the Company or its Affiliates any confidential or proprietary information of a third party without that party’s consent.

9. Withholding. All payments made by the Company under this Agreement shall be reduced by any tax or other amounts required to be withheld by the Company under applicable law.

10. Assignment. Neither you nor the Company may make any assignment of this Agreement or any interest in it, by operation of law or otherwise, without the prior written consent of the other; provided, however, the Company may assign its rights and obligations under this Agreement without your consent to an entity with which the Company shall hereafter effect a reorganization, consolidate with, or merge into or to which it transfers all or substantially all of its properties or assets. This Agreement shall inure to the benefit of and be binding upon you and the Company, and each of your and the Company’s respective successors, executors, administrators, heirs and permitted assigns.

11. Severability. If any portion or provision of this Agreement shall to any extent be declared illegal or unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or the application of such portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable, shall not be affected thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent permitted by law.

12. Miscellaneous. This Agreement, together with the Confidentiality, IA, and Restrictive Covenants Agreement and the Change of Control Agreement, set forth the entire agreement between you and the Company, and replace all prior and contemporaneous communications, agreements and understandings, written or oral, with respect to the terms and conditions of your employment, except any agreements specifically referenced herein, which will remain in effect subsequent to the execution of this Agreement. This Agreement may not be modified or amended, and no breach shall be deemed to be waived, unless agreed to in writing by you and an expressly authorized officer of the Company. The headings and captions in this Agreement are for convenience only and in no way define or describe the scope or content of any provision of this Agreement. This Agreement may be executed in two or more counterparts, each of which shall be an original and all of which together shall constitute one and the same instrument. This Agreement may be executed and delivered via electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act or other applicable law) or other transmission method and shall be deemed to have been duly and validly delivered and be valid and effective for all purposes. Provisions of this Agreement shall survive any termination or expiration hereof or any termination of your employment if so provided in this Agreement or necessary or desirable to accomplish the purpose of other surviving provisions. This is a Commonwealth of Massachusetts contract and shall be governed and construed in accordance with the laws of the Commonwealth of Massachusetts, without regard to any conflict of laws principles that would result in the application of the laws of any other

jurisdiction. You and the Company may enter into separate agreements related to equity, confidentiality, inventions assignment, and/or restrictive covenants. These separate agreements shall govern other aspects of the relationship between you and the Company, may have provisions that survive termination of your employment, shall be amended or superseded without regard to this Agreement, and shall be enforceable according to their terms without regard to the enforcement provision of this Agreement. You and the Company agree to submit to the exclusive jurisdiction of the courts of the Commonwealth of Massachusetts in connection with any dispute arising out of this Agreement or your employment with the Company.

13. Notices. Any notices provided for in this Agreement shall be in writing and shall be effective when delivered in person or deposited in the United States mail, postage prepaid, and addressed to you at your last known address on the books of the Company or, in the case of the Company, to it at its principal place of business, attention of the Chief Human Resources Officer, or to such other address as either party may specify by notice to the other actually received.

14. Counsel; Review Period. You acknowledge that the Company provided you with this Agreement (in draft form) by the earlier of (i) the date of a formal offer of employment from the Company or (ii) ten (10) business days before the Start Date. You acknowledge that you have been and are hereby advised of your right to consult an attorney before signing this Agreement.

15. Contingencies. This offer is valid until withdrawn or for five (5) days, whichever is shorter, and is contingent upon satisfactory completion of background and reference checks and your compliance with the Immigration Reform and Control Act of 1986.

We look forward to having you join the Waters team and anticipate that this will be a mutually beneficial relationship. If the foregoing is acceptable to you, please sign this letter in the space provided and return it to me, along with your signed Confidentiality, IA, and Restrictive Covenants Agreement.


Sincerely yours,

Waters Technologies Corporation

$11

$4 million at June 29, 2024 and $8

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

Income Taxes	6 Months Ended
Income Taxes	Jun. 29, 2024
Income Tax Disclosure [Abstract]
Income Taxes	7 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 June 29, 2024. 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 six months ended June 29, 2024 and July 1, 2023 by $5 million and $7 million, respectively, and increased the Company’s net income per diluted share by $0.09 and $0.11, respectively. The Company’s effective tax rate for the three months ended June 29, 2024 and July 1, 2023 was 15.7% and 16.5%, respectively. The decrease between the effective tax rates can be primarily attributed to a higher tax benefit related to stock-based compensation in the three months ended June 29, 2024, with the remaining difference due to the proportionate amounts of pre-tax income recognized in jurisdictions with different effective tax rates. The Company’s effective tax rate for the six months ended June 29, 2024 and July 1, 2023 was 13.8% and 15.6%, respectively. The decrease between the effective tax rates can primarily be attributed to a higher tax benefit related to stock-based compensation in 2024, the impact of discrete tax benefits in the current year and differences in the proportionate amounts of pre-tax income recognized in jurisdictions with different effective tax rates. 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 June 29, 2024 and July 1, 2023 were $15 million and $30 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, 2018. 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 and six months ended June 29, 2024. The Company continues to monitor the adoption of the Pillar Two rules in additional jurisdictions.

Commitments and Contingencies Disclosure [Abstract]
Other Commitments and Contingencies	9 Other Commitments and Contingencies The Company licenses certain technology and software from third parties in the course of ordinary business. Future minimum license fees payable under existing license agreements as of June 29, 2024 are immaterial for the years ended December 31, 2024 and thereafter. 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.
