What STE's management wrote with each quarter's results: the press release (8-K item 2.02, exhibit 99) and, when the company files them, its prepared remarks or the call transcript. The call itself is not filed with SEC, so most quarters have the release only.

Adjusted vs GAAP earnings per share

in the company's own words

In its release of 2026-11-04, STE reported $2.19 per share under GAAP and $2.94 on its own adjusted basis: the adjusted number is +34% above GAAP.

The company's words, latest release
Fiscal 2027 second quarter as reported diluted EPS increased to $2.19 release
Fiscal 2027 second quarter as reported diluted EPS increased to $2.19; adjusted EPS per diluted share increased to $2.94 release

What the company says its adjusted numbers leave out:

Adjusted net income, adjusted gross profit, adjusted EPS and adjusted income from operations exclude the amortization of intangible assets acquired in business combinations, acquisition and divestiture related transaction costs and gains or losses, integration costs related to acquisitions, tax restructuring costs, restructuring charges (credits), and certain other unusual or non- recurring items. release Nov 4, 2026

Both numbers are read from the words of each release (usually the highlights), never computed by us; hover a number for its sentence. Quarters where the release gives them only in a table are not shown. The company decides what "adjusted" leaves out; the full reconciliation is in the release.

STERIS Announces Financial Results for Fiscal 2027 Second Quarter • Fiscal 2027 second quarter revenue increased 9%; constant currency organic revenue growth was 8%

• Outlook updated to reflect solid underlying performance and the benefit of tariff refunds

DUBLIN, IRELAND - (November 4, 2026) - STERIS plc (NYSE: STE) (“STERIS” or the “Company”) today announced financial results for its fiscal 2027 second quarter ended September 30, 2026. Total revenue for the second quarter of fiscal 2027 increased 9% to $1.6 billion compared with $1.5 billion in the second quarter of fiscal 2026. Constant currency organic revenue growth was 8% in the second quarter.

“We are pleased with our second quarter performance,” said Dan Carestio, President and CEO of STERIS. “Life Sciences delivered particularly strong performance in the quarter, giving us confidence to raise our expectations for the segment for the full year. Our updated outlook reflects stable underlying performance, plus the benefit of tariff refunds received year-to-date. Fiscal 2027 is shaping up to be another record year for STERIS, supported by solid underlying demand and excellent execution from our commercial teams.”

As reported, net income for the second quarter was $213.7 million, or $2.19 per diluted share, compared with net income of $191.9 million, or $1.94 per diluted share, in the second quarter of fiscal 2026. Adjusted net income for the second quarter of fiscal 2027 was $286.8 million, or $2.94 per diluted share, compared with the previous year’s second quarter of $244.5 million or $2.47 per diluted share. For the second quarter, the pre-tax impact of tariff refunds on as reported results was a benefit of approximately $20 million. Gross tariff costs were flat with the prior year at $15 million for the quarter.

revenue as reported grew 9% in the second quarter to $1.1 billion compared with $1.0 billion in the second quarter of fiscal 2026. The as reported performance reflected 10% improvement in service revenue, 10% growth in consumables revenue, and a 4% increase in capital equipment revenue. Constant currency organic revenue growth was 7%. Healthcare operating income was $269.2 million compared with $259.5 million in last year’s second quarter. The increase in operating income was primarily due to improved volume and price which were partially offset by inflation, lower productivity and investments.

increased 5% as reported to $295.6 million compared with $281.5 million in the same period last year. This performance reflected 5% growth in service revenue and a 21% decline in capital equipment revenue. Constant currency organic revenue growth was 5%. Segment operating income was $132.1 million in the second quarter of fiscal 2027, compared with operating income of $127.6 million in the same period last year. The increase in operating income compared with the prior year primarily reflects improved price, which was partially offset by inflation and increased depreciation.

second quarter revenue as reported increased 18% to $170.6 million compared with $145.0 million in the second quarter of fiscal 2026. This performance reflected 53% growth in capital equipment revenue, 9% improvement in consumables revenue, and 5% growth in service revenue. Constant currency organic revenue increased 18%. Operating income increased to $75.8 million in the second quarter of fiscal 2027 compared with $59.9 million in the prior year’s second quarter. The increase in operating income reflects improvement in price, productivity, volume and favorable mix.

Net cash provided by operations for the first six months of fiscal 2027 was $656.1 million, compared with $707.8 million in the first six months of fiscal 2026. Free cash flow for the first six months of fiscal 2027 was $492.5 million compared with $527.7 million in the prior year period. The decrease in cash flow from operations and free

cash flow was driven primarily by a significantly lower contribution from working capital in fiscal 2027 compared with fiscal 2026, partially offset by higher net income.

During the quarter, the Company approved a separate targeted restructuring plan, in addition to the plan announced on August 5, 2026. The additional plan includes targeted facility realignment, product rationalization and select organizational realignment, primarily in the Healthcare segment. The Company anticipates total charges of approximately $45 million associated with the plan, including approximately $10 million in cash expenditures and $35 million in non- cash charges. Charges associated with the second quarter of fiscal 2027 are approximately $25 million. The plan is expected to generate annualized savings of approximately $9 million, with a portion realized in fiscal 2028 and the full benefit realized in subsequent fiscal years.

The Company is updating its prior outlook for revenue and earnings for fiscal 2027. Expectations for consolidated revenue growth are unchanged and include as reported revenue growth of 7-8% and constant currency organic revenue growth of 6-7%. Adjusted earnings per diluted share are now anticipated to be in the range of $11.35 to $11.55, an increase from prior expectations of $11.10 to $11.30. The revised outlook includes the benefit of approximately $0.18 from tariff refunds received year-to-date. All other elements of the most recently provided outlook remain unchanged.

Current Outlook Prior Outlook Healthcare 6-7% 6-7% Applied Sterilization Technologies 6-7% 7-8% Life Sciences 9-10% 6-7%

STERIS will provide revised fiscal 2027 outlook inclusive of the proposed Xodus Medical acquisition after closing.

Adjusted net income, adjusted income from operations, free cash flow, adjusted EPS and constant currency organic revenue are non-GAAP measures that may be used from time to time and should not be considered replacements for U.S. GAAP results. Non-GAAP financial measures are presented in this release with the intent of providing greater transparency to supplemental financial information used by management and the Board of Directors in their financial analysis and operational decision making. These amounts are disclosed so that the reader has the same

financial data that management uses with the belief that it will assist investors and other readers in making comparisons to our historical operating results and analyzing the underlying performance of our operations for the periods presented. The Company believes that the presentation of these non-GAAP financial measures, when considered along with our U.S. GAAP financial measures, provides a more complete understanding of the factors and trends affecting our business than could be obtained absent this disclosure.

Adjusted net income, adjusted gross profit, adjusted EPS and adjusted income from operations exclude the amortization of intangible assets acquired in business combinations, acquisition and divestiture related transaction costs and gains or losses, integration costs related to acquisitions, tax restructuring costs, restructuring charges (credits), and certain other unusual or non- recurring items. STERIS believes these measures are useful because they exclude items that may not be indicative of or are unrelated to our core operating results and provide a baseline for analyzing trends in our underlying businesses.

The Company defines free cash flow as cash flows from operating activities less purchases of property, plant, equipment and intangibles, plus proceeds from the sale of property, plant, equipment, and intangibles. STERIS believes that free cash flow is a useful measure of the Company’s ability to fund future principal debt repayments and growth outside of core operations, pay cash dividends, and repurchase ordinary shares.

To measure the percentage organic revenue growth, the Company removes the impact of significant acquisitions and divestitures that affect the comparability and trends in revenue. To measure the percentage constant currency organic revenue growth, the impact of changes in currency exchange rates and acquisitions and divestitures that affect the comparability and trends in revenue are removed. The impact of changes in currency exchange rates is calculated by translating current year results at prior year average currency exchange rates.

Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies’ non-GAAP financial measures having the same or similar names. These adjusted financial measures should not be considered in isolation or as a substitute for reported sales, gross profit, operating income, net earnings and net earnings per diluted share, the most directly comparable U.S. GAAP financial measures. These non-GAAP financial measures are an additional way of viewing aspects of the Company’s operations that, when viewed with U.S. GAAP results and the reconciliations to corresponding U.S. GAAP financial measures below, provide a more complete understanding of the business. The Company strongly encourages investors and shareholders to review its financial statements and publicly-filed reports in their entirety and not to rely on any single financial measure.

STERIS plc Segment Data (in millions) Financial information for each of the segments is presented in the following table. We disclose a measure of segment income that is consistent with the way management operates and views the business.

The following table presents a financial measure which is considered to be "non-GAAP financial measures" under Securities Exchange Commission rules. Free cash flow is defined by the Company as cash flows from operating activities less purchases of property, plant, equipment and intangibles (capital expenditures) plus proceeds from the sale of property, plant, equipment and intangibles. The Company uses free cash flow as a measure to gauge its ability to pay cash dividends, fund growth outside of core operations, fund future debt principal repayments, and repurchase shares. STERIS's calculation of free cash flows may vary from other companies.

Non-GAAP financial measures are presented with the intent of providing greater transparency to supplemental financial information used by management and the Board of Directors in their financial analysis and operational decision making. These amounts are disclosed so that the reader has the same financial data that management uses with the belief that it will assist investors and other readers in making comparisons to our historical operating results and analyzing the underlying performance of our operations for the periods presented.

It is important for the reader to note that the non-GAAP financial measure used may be calculated differently from, and therefore may not be comparable to, a similarly titled measure used by other companies. To measure the percentage organic revenue growth, the Company removes the impact of acquisitions and divestitures that affect the comparability and trends in revenue. To measure the percentage constant currency organic revenue growth, the impact of changes in currency exchange rates and acquisitions and divestitures that affect the comparability and trends in revenue are removed. The impact of changes in currency exchange rates is calculated by translating current year results at prior year average currency exchange rates.

Net cash provided by operations for the first six months of fiscal 2027 was
$656.1 million, compared with $707.8 million in the first six months of fiscal
2026. Free cash flow for the first six months of fiscal 2027 was $492.5 million
compared with $527.7 million in the prior year period. The decrease in cash flow
from operations and free

cash flow was driven primarily by a significantly lower contribution from
working capital in fiscal 2027 compared with fiscal 2026, partially offset by
higher net income.
                                                                                
  Restructuring                                                                 
                                                                                
During the quarter, the Company approved a separate targeted restructuring plan,
in addition to the plan announced on August 5, 2026. The additional plan
includes targeted facility realignment, product rationalization and select
organizational realignment, primarily in the Healthcare segment. The Company
anticipates total charges of approximately $45 million associated with the plan,
including approximately $10 million in cash expenditures and $35 million in non-
cash charges. Charges associated with the second quarter of fiscal 2027 are
approximately $25 million. The plan is expected to generate annualized savings
of approximately $9 million, with a portion realized in fiscal 2028 and the full
benefit realized in subsequent fiscal years.
                                                                                
  Fiscal 2027 Outlook                                                           
                                                                                
The Company is updating its prior outlook for revenue and earnings for fiscal
2027. Expectations for consolidated revenue growth are unchanged and include as
reported revenue growth of 7-8% and constant currency organic revenue growth of
6-7%. Adjusted earnings per diluted share are now anticipated to be in the range
of $11.35 to $11.55, an increase from prior expectations of $11.10 to $11.30.
The revised outlook includes the benefit of approximately $0.18 from tariff
refunds received year-to-date. All other elements of the most recently provided
outlook remain unchanged.

  Non-GAAP Financial Measures                                                   
                                                                                
Adjusted net income, adjusted income from operations, free cash flow, adjusted
EPS and constant currency organic revenue are non-GAAP measures that may be used
from time to time and should not be considered replacements for U.S. GAAP
results. Non-GAAP financial measures are presented in this release with the
intent of providing greater transparency to supplemental financial information
used by management and the Board of Directors in their financial analysis and
operational decision making. These amounts are disclosed so that the reader has
the same

financial data that management uses with the belief that it will assist
investors and other readers in making comparisons to our historical operating
results and analyzing the underlying performance of our operations for the
periods presented. The Company believes that the presentation of these non-GAAP
financial measures, when considered along with our U.S. GAAP financial measures,
provides a more complete understanding of the factors and trends affecting our
business than could be obtained absent this disclosure.

Adjusted net income, adjusted gross profit, adjusted EPS and adjusted income
from operations exclude the amortization of intangible assets acquired in
business combinations, acquisition and divestiture related transaction costs and
gains or losses, integration costs related to acquisitions, tax restructuring
costs, restructuring charges (credits), and certain other unusual or non-
recurring items. STERIS believes these measures are useful because they exclude
items that may not be indicative of or are unrelated to our core operating
results and provide a baseline for analyzing trends in our underlying
businesses.

The Company defines free cash flow as cash flows from operating activities less
purchases of property, plant, equipment and intangibles, plus proceeds from the
sale of property, plant, equipment, and intangibles. STERIS believes that free
cash flow is a useful measure of the Company’s ability to fund future principal
debt repayments and growth outside of core operations, pay cash dividends, and
repurchase ordinary shares.

To measure the percentage organic revenue growth, the Company removes the impact
of significant acquisitions and divestitures that affect the comparability and
trends in revenue. To measure the percentage constant currency organic revenue
growth, the impact of changes in currency exchange rates and acquisitions and
divestitures that affect the comparability and trends in revenue are removed.
The impact of changes in currency exchange rates is calculated by translating
current year results at prior year average currency exchange rates.

Because non-GAAP financial measures are not standardized, it may not be possible
to compare these financial measures with other companies’ non-GAAP financial
measures having the same or similar names. These adjusted financial measures
should not be considered in isolation or as a substitute for reported sales,
gross profit, operating income, net earnings and net earnings per diluted share,
the most directly comparable U.S. GAAP financial measures. These non-GAAP
financial measures are an additional way of viewing aspects of the Company’s
operations that, when viewed with U.S. GAAP results and the reconciliations to
corresponding U.S. GAAP financial measures below, provide a more complete
understanding of the business. The Company strongly encourages investors and
shareholders to review its financial statements and publicly-filed reports in
their entirety and not to rely on any single financial measure.

any outcome regarding matters described in STERIS’s securities filings or
otherwise with respect to any regulatory action, administrative proceedings,

business strategies, earnings or revenue trends or future financial results.
Other potential risks and uncertainties that could cause actual results to
differ materially from those in the forward-looking statements include, without
limitation, (a) the impact on STERIS and its operations of any legislation,
regulations or orders, including but not limited to any

new trade regulations or orders, that may be implemented by the U.S.
administration or Congress, or of any responses thereto by non-U.S. governments,
(b) operating costs, pressure on pricing (including, without limitation, as a
result of inflation), Customer loss and business disruption (including, without
limitation, difficulties in maintaining relationships with employees, Customers,
clients or suppliers) being greater than expected and leading to erosion of

rulings, certifications, regulations, or other regulatory actions, or the
outcome of any pending or threatened litigation, may delay, limit or prevent new
product or service introductions, impact production, supply and/or marketing of
existing products or services, result in uncovered costs, or otherwise affect
STERIS’s performance, results, prospects or value, (f) changes in tax laws or
interpretations or the adoption of certain income tax treaties in jurisdictions
where STERIS operates that could increase its consolidated tax liabilities,
including changes in tax laws that would result in STERIS being treated as a
U.S. resident for U.S. federal tax purposes, or the impact of tariffs and/or
other trade barriers as a result of STERIS’s corporate structure, (g) the
impacts of increasing consolidation and competition within STERIS’s industry,
which may exert pressure on its pricing strategy, manufacturing strategy or lead
to decreasing demand for its products and services, (h) the effects on STERIS’s
operations resulting from labor-related issues, such as strikes, unsuccessful
union negotiations and other workforce disruptions or from its inability to
recruit or retain management and other personnel, (i) the level of STERIS’s
indebtedness limiting financial flexibility or increasing future borrowing
costs, (j) the effects of changes in credit availability and pricing, as well as
the ability of STERIS and STERIS’s Customers and suppliers to adequately access
the credit markets, on favorable terms or at all, when needed, (k) the
possibility that anticipated financial results, anticipated revenues,
productivity improvements, cost savings, growth synergies, and other anticipated
benefits of acquisitions, restructuring efforts, and divestitures will not be
realized or will be less than anticipated due to unknown or inestimable
liabilities, impairments, or increases in expected integration costs or
difficulties in connection with the integration of acquired businesses, (l) the
possibility that expectations about the benefits, charges and cash expenditures
from the new Center of Excellence in North Carolina and the related facility
consolidation plan may not be accurate or realized on anticipated timelines, or
at all, (m) the risk that regulatory approvals that are required to complete the
acquisition of Xodus Medical, Inc. (the “Acquisition”) may not be received, may
take longer than expected or may impose adverse conditions and STERIS’s ability
to complete the Acquisition on the expected timeline, or at all, (n) the risk
that the cost savings, tax benefits and other synergies expected from the
Acquisition may not be realized or may take longer to realize than expected,
including that the Acquisition may not be accretive or produce the expected cash
tax benefits within the expected timeframe or to the extent anticipated, and (o)
other risks described in STERIS’s most recent Annual Report on Form 10-K and
other reports filed with the Securities and Exchange Commission.

Readers are cautioned not to place undue reliance on any forward-looking
statements included in this release, which speak only as of the date hereof.

  Financial information for each of the segments is   
  presented in the following table. We disclose a     
  measure of segment income that is consistent with   
  the way management operates and views the           
  business. The accounting policies for reportable    
  segments are the same as those for the              
  consolidated Company. Segment income is calculated  
  as the segment’s gross profit less direct costs     
  and indirect costs if the resources are dedicated   
  to a single segment. Corporate costs include        
  corporate and administrative functions, public      
  company costs, legacy post-retirement benefits,     
  certain services and facilities related to          
  distribution and research and development that are  
  shared by multiple segments, as well as the

  The following table presents a financial measure    
  which is considered to be "non-GAAP financial       
  measures" under Securities Exchange Commission      
  rules. Free cash flow is defined by the Company as  
  cash flows from operating activities less           
  purchases of property, plant, equipment and         
  intangibles (capital expenditures) plus proceeds    
  from the sale of property, plant, equipment and     
  intangibles. The Company uses free cash flow as a   
  measure to gauge its ability to pay cash            
  dividends, fund growth outside of core operations,  
  fund future debt principal repayments, and          
  repurchase shares. STERIS's calculation of free     
  cash flows may vary from other companies.

  Non-GAAP Financial Measures

  Non-GAAP financial measures are presented with the  
  intent of providing greater transparency to         
  supplemental financial information used by          
  management and the Board of Directors in their      
  financial analysis and operational decision         
  making. These amounts are disclosed so that the     
  reader has the same financial data that management  
  uses with the belief that it will assist investors  
  and other readers in making comparisons to our      
  historical operating results and analyzing the      
  underlying performance of our operations for the    
  periods presented.                                  
  Management and the Board of Directors believe that  
  the presentation of these non-GAAP financial        
  measures, when considered along with our U.S. GAAP  
  financial measures and the reconciliation to the    
  corresponding U.S. GAAP financial measures,         
  provides the reader with a more complete            
  understanding of the factors and trends affecting   
  our business than could be obtained absent this     
  disclosure. It is important for the reader to note  
  that the non-GAAP financial measure used may be     
  calculated differently from, and therefore may not  
  be comparable to, a similarly titled measure used   
  by other companies.                                 
  To measure the percentage organic revenue growth,   
  the Company removes the impact of acquisitions and  
  divestitures that affect the comparability and      
  trends in revenue. To measure the percentage        
  constant currency organic revenue growth, the       
  impact of changes in currency exchange rates and    
  acquisitions and divestitures that affect the       
  comparability and trends in revenue are removed.    
  The impact of changes in currency exchange rates    
  is calculated by translating current year results   
  at prior year average currency exchange rates.

  This supplemental data is consistent with publicly disclosed information      
  provided in quarterly conference calls, earnings releases and SEC filings,    
  and is subject to all definitions, precautions and limitations contained in   
  those disclosures. Please see the Company's most recent 10-K for definitions  
  (and reconciliation where appropriate) of adjusted measures, backlog, free    
  cash flow and net debt.                                                       
  *The Company expects to discontinue disclosure of backlog beginning in        
  fiscal 2028, as backlog has become a less meaningful indicator of future      
  revenue trends across the business.
