Please refer to the tables below for a reconciliation of the projected GAAP to non-GAAPfinancial outlook for the full-year and fourth 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. All amounts, other than percentages and per share data, are presented in millions of dollars. Certain totals and percentages may not recalculate due to rounding.

Results for the acquired Biosciences and Diagnostic Solutions businesses (the “BDS Businesses”) for the prior year comparable period are the quarterly results for the Biosciences and Diagnostic Solutions business units for the three months ended September 30, 2025, as reported in Exhibit 99.1 of the current report on Form 8-Kfiled by Becton, Dickinson and Company (“BDX”) with the Securities and Exchange Commission (“SEC”) on November6, 2025. This historical financial information reflects the results of operations of these businesses as they were historically managed by BDX in conformity with U.S. GAAP. Therefore, such historical financial information does not necessarily reflect what these businesses’ results of operations would have been had they operated as a part of Waters during the period presented, and does not reflect changes that have occurred since the consummation of the acquisition of these businesses by Waters, including, among other things, changes in the financing, cash management, operations, cost structure and personnel needs or differences in accounting policies. For example, BDX provided certain services, such as legal, finance, information technology, human resources, and other infrastructure support to the BDS Businesses prior to their acquisition by Waters. Costs of these services were included in the BDS Businesses’ results of operations through allocations based upon a proportion of revenue or headcount as determined by BDX in conformity with GAAP. Such allocated costs may not be indicative or necessary if the BDS Businesses operated as a part of Waters during the period presented, nor are they necessarily representative of the costs that may be incurred in the future.

Waters Corporation will webcast its third quarter 2026 financial results conference call today, November 3, 2026, at 8:00 a.m. Eastern Time. To listen to the call and see the accompanying slide presentation, please visit , select “Investor Relations” under the “About Waters” section, navigate to “Events & Presentations,” and click on the “Webcast.” A replay will be available through at least December 1, 2026.

This release contains financial measures, such as organic constant currency growth rates, constant currency growth rates, prior year comparable revenue, and adjusted earnings per diluted share, among others, which are considered “non- GAAP” financial measures under applicable SEC 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.

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 the Biosciences and Diagnostic Solutions businesses from BDX, including failure to realize the anticipated benefits of this acquisition, including as a result of delay in integrating the BDS Businesses 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, the anticipated benefits of the MOBILion Systems, Inc. acquisition, 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, our ability to 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 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 Company believes that referring to comparable organic constant currency growth is a useful measure for evaluating the underlying performance of revenue. Organic constant currency revenue 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 rate changes during the current period and excluding the impact of acquisitions completed within twelve months of the acquisition date. See description of non-GAAP (a) financial measures contained in this release. ──────────────────────────────────────────────────────────────────────────────

The Company believes that referring to comparable revenue is a useful measure for evaluating the underlying performance of the business following the acquisition of Biosciences & Diagnostic Solutions (“BDS”). Comparable revenue includes BDS revenue in both the current and prior year comparison periods. Current period revenue includes BDS revenue for the full quarter and prior year comparable revenue includes an estimate of BDS revenue for the equivalent prior year (b) period. Growth rates are calculated using these comparable revenues. ──────────────────────────────────────────────────────────────────────────────

The Company believes that referring to comparable organic constant currency growth is a useful measure for evaluating the underlying performance of revenue. Organic constant currency revenue 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 rate changes during the current period and excluding the impact of acquisitions completed within twelve months of the acquisition date. See description of non-GAAP (a) financial measures contained in this release. ──────────────────────────────────────────────────────────────────────────────

Waters Corporation revenue for the nine months ended October 3, 2026 includes the results of the BDS Business acquisition from date of acquisition February 9, 2026 through (b) October 3, 2026. ──────────────────────────────────────────────────────────────────────────────

The Company believes that referring to comparable revenue is a useful measure for evaluating the underlying performance of the business following the acquisition of Biosciences & Diagnostic Solutions (“BDS”). Comparable revenue includes BDS revenue in both the current and prior year comparison periods. Current period revenue includes BDS revenue from February 9, 2026, the acquisition date, through quarter-end. Prior year comparable revenue includes an estimate of BDS revenue for the equivalent prior year period. Growth rates are (c) calculated using these comparable revenues. ──────────────────────────────────────────────────────────────────────────────

Waters Corporation and Subsidiaries Reconciliation of GAAP to Adjusted Non- GAAPFinancials Three and Nine Months Ended October 3, 2026 and September 27, 2025 (In millions, except per share data)

Selling & administrative expenses include purchased intangibles (a) amortization and restructuring and other charges.

The purchased intangibles amortization and acquisition-related inventory and fixed asset fair value step-ups, which are non-cash (b) 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.

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

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 (d) 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.

Acquisition related costs include all incremental costs incurred to effect the business combination, such as (e) 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.

In connection with the Wyatt acquisition, the Company recognized a two-year retention bonus obligation that is contingent upon the (f) 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.

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 (g) 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.

Adjusted diluted earnings per share is calculated using diluted weighted-average shares outstanding of 93.1 million for the nine months ended October 3, 2026. While the Company reported a GAAP net loss for the period and therefore excluded potentially dilutive securities from its GAAP diluted earnings per share calculation, adjusted net income was positive for the period. Accordingly, potentially dilutive securities were included in the calculation of (h) adjusted diluted earnings per share. ──────────────────────────────────────────────────────────────────────────────

Waters Corporation and Subsidiaries Preliminary Condensed Unclassified Consolidated Balance Sheets (In millions and unaudited) October 3, 2026 December 31, 2025 ────────────────────────────────────────────────────────────────────────────── Cash and cash equivalents $ 593 $ 588 Accounts receivable 1,464 829 Inventories 1,324 572 Property, plant and equipment, 1,458 642 net Intangible assets, net 8,275 558 Goodwill 9,369 1,340 Other assets 1,632 548 Total assets $ 24,115 $ 5,077 Notes payable and debt $ 5,133 $ 1,407 Other liabilities 3,691 1,108 Total liabilities 8,824 2,515 Total stockholders’ equity 15,291 2,562 Total liabilities and stockholders’ $ 24,115 $ 5,077 equity

The Company defines free cash flow as net cash flow from operations accounted for under GAAP less capital (a) expenditures and software capitalizations plus or minus any unusual and non recurring items. Free cash flow is not a GAAP measurement and may not be comparable to free cash flow reported by other companies.

Includes an increase in net receivables of $17 million and $174 million for the three and nine months (b) ended October 3, 2026, respectively, due from the BDS acquisition TSA provider related to the initial net cash settlement for activities occurring since the acquisition date.

During the nine months ended September 27, 2025, the Company made retention payments under the Wyatt retention bonus program. The Company believes that these payments are (c) not normal and do not represent future ongoing business expenses. ──────────────────────────────────────────────────────────────────────────────

As part of the BDS acquisition, a portion of the total consideration paid was reflected as a deposit asset on the opening balance sheet, which is attributable to the Company’s present right to the future economic benefits of the business in those foreign jurisdictions where legal and beneficial title had not transferred to the Company as of February 9, 2026. Changes in the deposit asset are driven by changes in the underlying assets and liabilities in those foreign jurisdictions, which represent productive assets and therefore the cash payments (or cash receipts) resulting from the changes in these productive assets are classified as investing cash flows. The change in the deposit asset is primarily related to the collection of third party customer receivables that existed as of February 9, 2026. The Company considers cash collected from customers as a component of free cash flow as it (d) represents amounts collected from its core operations. ──────────────────────────────────────────────────────────────────────────────

Organic constant currency revenue 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. 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 (a) 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.

MILFORD, Mass., November 3, 2026 - Waters Corporation (NYSE: WAT)today announced
its financial results for the third quarter of 2026. Overall Financial Results

acquired Biosciences and Diagnostic Solutions businesses. Organic revenue for
the third quarter of 2026 was $871 million, compared to $800million for the
third quarter of 2025, representing an increase of 9% as reported and 10% in
constant currency. Revenue from Biosciences and Diagnostic Solutions was $896
million for the third quarter of 2026, compared to $885million on a prior year
comparable basis. On a GAAP basis, the Company reported a diluted earnings per
share of $0.82 for the third quarter of 2026, compared to diluted EPS of $2.50
for the third quarter of 2025, reflecting acquisition-related purchase
accounting charges, acquisition-related costs, and restructuring costs. Adjusted

third quarter of 2025. “Our team delivered exceptional results led by best-in-
class consumables growth across both our Analytical Sciences and Biosciences
divisions, as strong execution, new product innovation, and rising customer
testing volume accelerated growth,” said Dr. Udit Batra, President & Chief
Executive Officer, Waters Corporation. “LC-MS instrument growth also
strengthened, growing double-digits in constant currency, driven by robust
instrument replacement trends, idiosyncratic growth drivers across GLP-1s, PFAS
and India generics, and we continued to outperform the market with our leading
solutions for complex biologics.”

Dr. Batra continued, “Thanks to the hard work of our teams, we are delivering
ahead of schedule on our
synergy and integration commitments for our acquired businesses. With improving
end market conditions and momentum accelerating across the combined company, we

Starting 2027 Growth Framework

Management will provide the Company’s 2027 starting growth framework during its
scheduled earnings conference call today at 8:00 a.m. ET, outlining how
reshoring, synergies and AI-related demand drivers are expected to shape next
year’s growth.

Announcing Acquisition of MOBILion Systems, Inc.

The Company also announced today that it has acquired MOBILion Systems, Inc..
MOBILion is the pioneer of SLIM high-resolution ion mobility separation
technology for complex molecular analysis, which separates molecules by size,
shape and charge in milliseconds. The acquisition complements Waters’ industry-
leading mass spectrometry portfolio and is expected to broaden the Company’s
entry into the proteomics market. Additional details are available in a separate
release issued earlier today.

Please refer to the tables below for a reconciliation of the projected GAAP to
non-GAAPfinancial outlook for the full-year and fourth 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. All amounts, other than percentages and per share data,
are presented in millions of dollars. Certain totals and percentages may not
recalculate due to rounding.

Results for the acquired Biosciences and Diagnostic Solutions businesses (the
“BDS Businesses”) for the prior year comparable period are the quarterly results
for the Biosciences and Diagnostic Solutions business units for the three months
ended September 30, 2025, as reported in Exhibit 99.1 of the current report on
Form 8-Kfiled by Becton, Dickinson and Company (“BDX”) with the Securities and
Exchange Commission (“SEC”) on November6, 2025. This historical financial
information reflects the results of operations of these businesses as they were
historically managed by BDX in conformity with U.S. GAAP. Therefore, such
historical financial information does not necessarily reflect what these
businesses’ results of operations would have been had they operated as a part of
Waters during the period presented, and does not reflect changes that have
occurred since the consummation of the acquisition of these businesses by
Waters, including, among other things, changes in the financing, cash
management, operations, cost structure and personnel needs or differences in
accounting policies. For example, BDX provided certain services, such as legal,
finance, information technology, human resources, and other infrastructure
support to the BDS Businesses prior to their acquisition by Waters. Costs of
these services were included in the BDS Businesses’ results of operations
through allocations based upon a proportion of revenue or headcount as
determined by BDX in conformity with GAAP. Such allocated costs may not be
indicative or necessary if the BDS Businesses operated as a part of Waters
during the period presented, nor are they necessarily representative of the
costs that may be incurred in the future.

Non-GAAPFinancial Measures

This release contains financial measures, such as organic constant currency
growth rates, constant currency growth rates, prior year comparable revenue, and
adjusted earnings per diluted share, among others, which are considered “non-
GAAP” financial measures under applicable SEC 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.

       The Company believes that referring to comparable organic constant       
       currency growth is a useful measure for                                  
       evaluating the underlying performance of revenue. Organic constant       
       currency revenue 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 rate changes during the current  
       period and excluding the impact of acquisitions completed within twelve  
       months of the acquisition date. See description of non-GAAP

       The Company believes that referring to comparable revenue is a useful    
       measure for evaluating the underlying                                    
       performance of the business following the acquisition of Biosciences &   
       Diagnostic Solutions (“BDS”). Comparable revenue includes BDS revenue    
       in both the current and prior year comparison periods. Current period    
       revenue includes                                                         
       BDS revenue for the full quarter and prior year comparable revenue       
       includes an estimate of BDS revenue for the equivalent prior year        
  (b)  period. Growth rates are calculated using these comparable revenues.

       The Company believes that referring to comparable organic constant       
       currency growth is a useful measure for                                  
       evaluating the underlying performance of revenue. Organic constant       
       currency revenue 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 rate changes during the current  
       period and excluding the impact of acquisitions completed within twelve  
       months of the acquisition date. See description of non-GAAP

       The Company believes that referring to comparable revenue is a useful    
       measure for evaluating the underlying                                    
       performance of the business following the acquisition of Biosciences &   
       Diagnostic Solutions (“BDS”). Comparable revenue includes BDS revenue    
       in both the current and prior year comparison periods. Current period    
       revenue includes                                                         
       BDS revenue from February 9, 2026, the acquisition date, through         
       quarter-end. Prior year comparable revenue includes an estimate of BDS   
       revenue for the equivalent prior year period. Growth rates are           
  (c)  calculated using these comparable revenues.

       Selling & administrative expenses include purchased intangibles          
  (a)  amortization and restructuring and                                       
       other charges.                                                           
                                                                                
                                                                                
       The purchased intangibles amortization and acquisition-related           
       inventory and fixed asset fair value step-ups, which are non-cash        
  (b)  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.           
                                                                                
                                                                                
       Restructuring costs and certain other items were excluded as the         
       Company believes that the cost to consolidate                            
  (c)  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.               
                                                                                
                                                                                
       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       
  (d)  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.               
                                                                                
                                                                                
       Acquisition related costs include all incremental costs incurred to      
       effect the business combination, such as                                 
  (e)  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.            
                                                                                
                                                                                
       In connection with the Wyatt acquisition, the Company recognized a       
       two-year retention bonus obligation that is contingent upon the          
  (f)  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.                              
                                                                                
                                                                                
       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       
  (g)  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.                                               
                                                                                
                                                                                
       Adjusted diluted earnings per share is calculated using diluted          
       weighted-average shares outstanding of 93.1 million for the nine months  
       ended October 3, 2026. While the Company reported a GAAP net loss for    
       the period and therefore excluded potentially dilutive                   
       securities from its GAAP diluted earnings per share calculation,         
       adjusted net income was positive for the period. Accordingly,            
       potentially dilutive securities were included in the calculation of      
  (h)  adjusted diluted earnings per share.

       The Company defines free cash flow as net cash flow from operations      
       accounted for under GAAP less capital                                    
  (a)  expenditures and software capitalizations plus or minus any unusual and  
       non recurring items. Free cash flow is not a GAAP measurement and may    
       not be comparable to free cash flow reported by other companies.         
                                                                                
                                                                                
       Includes an increase in net receivables of $17 million and $174 million  
       for the three and nine months                                            
  (b)  ended October 3, 2026, respectively, due from the BDS acquisition TSA    
       provider related to the initial net cash settlement for activities       
       occurring since the acquisition date.                                    
                                                                                
                                                                                
       During the nine months ended September 27, 2025, the Company made        
       retention payments under the Wyatt                                       
       retention bonus program. The Company believes that these payments are    
  (c)  not normal and do not represent future ongoing business expenses.        
 ────────────────────────────────────────────────────────────────────────────── 
                                                                                
                                                                                
       As part of the BDS acquisition, a portion of the total consideration     
       paid was reflected as a deposit asset on                                 
       the opening balance sheet, which is attributable to the Company’s        
       present right to the future economic benefits of the business in those   
       foreign jurisdictions where legal and beneficial title had not           
       transferred to the Company as of                                         
       February 9, 2026. Changes in the deposit asset are driven by changes in  
       the underlying assets and liabilities in those foreign jurisdictions,    
       which represent productive assets and therefore the cash payments (or    
       cash receipts) resulting from                                            
       the changes in these productive assets are classified as investing cash  
       flows. The change in the deposit asset is primarily related to the       
       collection of third party customer receivables that existed as of        
       February 9, 2026. The Company considers                                  
       cash collected from customers as a component of free cash flow as it     
  (d)  represents amounts collected from its core operations.

       Organic constant currency revenue 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. 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                               
  (a)  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.
