•

Organic revenue grew 13% as reported and 11% in constant currency, exceeding the high end of the constant

currency growth guidance range by 200 basis points – led by high-single-digit instrument growth and mid-teens chemistry growth within the Analytical Sciences Division.

•

The Biosciences and Diagnostic Solutions businesses generated $520 million of reported

revenue since the closing of the acquisition – $40 million above guidance – driven by traction from commercial execution and operational improvement initiatives launched during the quarter.

•

GAAP EPS of ($0.87); Adjusted EPS of $2.70 grew 20% year-over-year, driven by better-than-expected

revenue and margin performance.

•

The Company is raising its full year 2026 organic constant currency revenue growth guidance to 6.5% to

8.0% and now expects the acquired businesses to generate $3.035 billion of reported revenue in 2026. The Company is also raising its full-year 2026 adjusted EPS guidance to $14.40 to $14.60, reflecting double-digit adjusted EPS growth.

MILFORD, Mass., May 5, 2026 - Waters Corporation (NYSE: WAT), today announced its financial results for

the first quarter of 2026, marking the first reporting period that includes financial results for the Biosciences and Diagnostic Solutions businesses of Becton, Dickinson and Company, which was acquired by Waters on February 9, 2026.

Overall Financial Results

The

Company’s reported revenue for the first quarter of 2026 was $1.267 billion, reflecting $747 million of organic revenue and $520 million of revenue from Biosciences and Diagnostic Solutions from the

transaction closing date through to the end of the quarter.

Organic revenue for the first quarter of 2026 was $747 million, compared to

$662 million for the first quarter of 2025, representing an increase of 13% as reported and 11% in constant currency.

Revenue from

Biosciences and Diagnostic Solutions was $520 million on an owned-period basis within the quarter, compared to $485 million on an estimated prior-year equivalent basis.

On a GAAP basis, the Company reported a diluted loss per share of $0.87 for the first quarter of 2026, compared to diluted EPS of $2.03 for the first quarter

President & Chief Executive Officer, Waters Corporation. “Our Biosciences and Advanced Diagnostics Divisions are off to a strong start with a significant improvement in growth rates versus

pre-close trends, due to increased execution discipline, a sharper focus on upcoming new product launches, and superb collaboration with our Analytical Sciences Division which has already enabled the

realization of revenue synergies. In parallel, the instrument replacement cycle, success of new product launches, and our idiosyncratic growth drivers are continuing to fuel exceptional momentum in our organic revenue growth rates.”

Dr. Batra continued: “As we look ahead, we are raising our guidance to reflect the increased momentum

we are seeing across our businesses. Our teams are focused on executing a seamless integration, delivering industry-leading growth, and building a highly differentiated portfolio, positioning Waters for continued success for many years to

Full-Year and Second Quarter 2026 Financial Guidance

Full-Year 2026 Financial Guidance

The Company is raising

its full-year 2026 organic, constant currency revenue growth guidance to the range of 6.5% to 8.0%. Including the impact of currency translation, full-year 2026 organic reported revenue is expected to be in the range of $3.370 billion to

$3.420 billion. This guidance includes $15 million of expected revenue synergies.

The Company now expects full-year 2026 acquired business

reported revenue of approximately $3.035 billion on an owned-period basis, which includes $35 million of expected revenue synergies.

Total

Company reported revenue for full-year 2026 is expected to be in the range of $6.405 billion to $6.455 billion.

The Company is raising its

full-year 2026 adjusted EPS guidance to $14.40 to $14.60. This represents year-over-year adjusted EPS growth of 10% to 11%.

The Company expects second quarter 2026 adjusted EPS to be in the range of $2.95 to $3.05, which represents

flat to 3.4% year-over-year adjusted EPS growth.

Please refer to the

tables below for a reconciliation of the projected GAAP to non-GAAP financial outlook for the full-year and second quarter. The Company is unable to provide reconciliations of

forward-looking presentations of adjusted EPS guidance measures to the most directly comparable GAAP measures. Such reconciliations cannot be prepared without unreasonable efforts due to the inherent difficulty and unpredictability in forecasting

and quantifying certain amounts that would be necessary for such reconciliations, including acquisition-related amortization, acquisition and restructuring costs, as well as certain legal, advisory and tax costs, or other costs that may arise, which

amounts could be significant and could have a material impact on the Company’s future GAAP financial results.

Non-GAAP Financial Measures

This release contains financial measures, such as organic constant currency growth rates, constant currency growth rates, pro forma comparable revenue, and

adjusted earnings per diluted share, among others, which are considered “non-GAAP” financial measures under applicable U.S. Securities and Exchange Commission rules and regulations. These non-GAAP financial measures should be considered supplemental to, and not a substitute for, financial information prepared in accordance with U.S. generally accepted accounting principles (GAAP). The Company’s

definitions of these non-GAAP measures may differ from similarly titled measures used by others. The non-GAAP financial measures used in this release adjust for

specified items that can be highly variable or difficult to predict. The Company generally uses these non-GAAP financial measures to facilitate management’s financial and operational decision-making,

including evaluation of the Company’s historical operating results, comparison to competitors’ operating results and determination of management incentive compensation. These non-GAAP financial

measures reflect an additional way of viewing aspects of the Company’s operations that, when viewed with GAAP results and the reconciliations to corresponding GAAP financial measures, may provide a more complete understanding of factors and

trends affecting the Company’s business. Because non-GAAP financial measures exclude the effect of items that will increase or decrease the Company’s reported results of operations, management

strongly encourages investors to review the Company’s consolidated financial statements and publicly filed reports in their entirety. Definitions of the non-GAAP financial measures and reconciliations to

the most directly comparable GAAP financial measures are included in the tables accompanying this release.

Cautionary Statement

This release contains “forward-looking” statements regarding future results and events. For this purpose, any statements that are not statements of

historical fact may be deemed forward-looking statements. Without limiting the foregoing, the words “feels,” “believes,” “anticipates,” “plans,” “expects,” “intends,”

“suggests,” “appears,” “estimates,” “projects,” and similar expressions, whether in the negative or affirmative, are intended to identify forward-looking statements. Our actual results may differ

significantly from the results discussed in the forward-looking statements within this release for a variety of reasons, including and without limitation, risks or uncertainties related to our acquisition of Becton, Dickinson and Company’s

Biosciences and Diagnostic Solutions business (the “BDS Business”), including failure to realize the anticipated benefits of this acquisition, including as a result of delay in integrating the BDS Business with the Company on the

expected timeframe or at all, and the ability of the Company to implement its business strategy and achieve revenue and cost synergies, anticipated progress on Waters’ research programs, development of new analytical instruments and associated

software or consumables, manufacturing development and capabilities, our future financial and operational performance, future economic and market conditions, including our expectations about the growth rates of certain markets, our strategic

initiatives, including our instrument replacement initiatives, respond and adapt to changing global dynamics, including the potential impacts of tariffs and supply chain challenges, our ability to retain and attract customers in various geographies

and market segments, our market size and growth opportunities, our competitive positioning, projected costs, technological capabilities and plans, and objectives of management, and other risk factors detailed from time to time in Waters’

reports filed with the Securities and Exchange Commission (“SEC”). Such factors and others are discussed more fully in the sections entitled “Forward-Looking Statements” and “Risk Factors” of the Company’s

annual report on Form 10-K for the year ended December 31, 2025, as filed with the SEC, which discussions are incorporated by reference in this release, as updated by the Company’s subsequent

filings with the SEC. The forward-looking statements included in this release represent the Company’s estimates or views as of the date of this release and should not be relied upon as representing the Company’s estimates or views as of

any date subsequent to the date of this release. Except as required by law, the Company does not assume any obligation to update any forward-looking statements.

Percentage not meaningful

(a)

The Company believes that referring to comparable organic constant currency growth rates is a useful way to

evaluate the underlying performance of Waters Corporation’s net revenue. Organic constant currency growth, a non-GAAP financial measure, measures the change in net revenue between current and prior year

periods, excluding the impact of foreign currency exchange rates during the current period and excluding the impact of acquisitions made within twelve months of the acquisition close date. See description of

non-GAAP financial measures contained in this release.

(b)

Waters Corporation revenue for the three months ended April 4, 2026 includes the results of the BDS

Business acquisition from date of acquisition February 9, 2026 through April 4, 2026.

(c)

The Company believes that referring to pro forma comparable revenue is a useful way to evaluate the underlying

performance of the business. Pro forma comparable revenue reflects acquired company (Biosciences & Diagnostic Solutions) revenue where growth rates are presented on an as reported basis, covering revenue for the owned period portion of the

quarter from February 9, 2026, the transaction close date, through the end of the quarter, with growth compared against the pro forma comparable revenue estimate for the prior year equivalent partial quarter period that predates Waters’

ownership.

The amortization of purchased intangibles and acquisition-related inventory and fixed asset fair value step-up, which are non-cash expenses, were excluded to be consistent with how management evaluates the performance of its core business against historical operating results

and the operating results of competitors over periods of time.

(c)

Restructuring costs and certain other items were excluded as the Company believes that the cost to consolidate

operations, reduce overhead, and certain other income or expense items are not normal and do not represent future ongoing business expenses of a specific function or geographic location of the Company.

(d)

ERP implementation and transformation costs represent costs related to the Company’s initiative to

transition from its legacy enterprise resource planning (ERP) system to a new global ERP solution with a cloud-based infrastructure. These costs, which do not represent normal or future ongoing business expenses, are

one-time, non-recurring costs related to the establishment of our new global ERP solution that were determined to be

non-capitalizable in accordance with accounting standards.

(e)

Acquisition related costs include all incremental costs incurred to effect the business combination, such as

advisory, legal, accounting, tax, valuation, other professional fees, and integration costs. The Company believes that these costs are not normal and do not represent future ongoing business expenses.

(f)

In connection with the Wyatt acquisition, the Company recognized a

two-year retention bonus obligation that is contingent upon the employee’s providing future service and continued employment with Waters. The Company believes that these costs are not normal and do not

represent future ongoing business expenses.

(g)

Financing costs relate to certain financing fees incurred by the Company to secure access to certain debt

facilities in connection with the agreement Waters entered into to acquire the Biosciences and Diagnostics Solutions business of Becton, Dickinson & Company. The Company believes that these costs are not normal and do not represent future

ongoing business expenses.

(a)

Organic constant currency growth rates are a non-GAAP financial measure

that measures the change in net revenue between current and prior year periods, excluding the impact of foreign currency exchange rates during the current period and excluding the impact of acquisitions made within twelve months of the acquisition

close date. These amounts are estimated at the current foreign currency exchange rates and based on the forecasted geographical revenue in local currency, as well as an assessment of market conditions as of the date of this press release, and may

differ significantly from actual results.

These forward-looking adjustment estimates do not reflect future gains and

charges that are inherently difficult to predict and estimate due to their unknown timing, effect and/or significance.
