PART 1 - FINANCIAL INFORMATION

ITEM 2. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Introduction

In Managements Discussion and Analysis of Financial
Condition and Results of Operations (the MD&A), we explain the general financial condition and the results of operations for STERIS including:



| |  |  | what factors affect our business;
| | - |  | ---------------------------------



| |  |  | what our earnings and costs were in each period presented;
| | - |  | ----------------------------------------------------------



| |  |  | why those earnings and costs were different from prior periods;
| | - |  | ---------------------------------------------------------------



| |  |  | where our earnings came from;
| | - |  | -----------------------------



| |  |  | how this affects our overall financial condition;
| | - |  | -------------------------------------------------



| |  |  | what our expenditures for capital projects were; and
| | - |  | ----------------------------------------------------



| |  |  | where cash will come from to fund future debt principal repayments, growth outside of core operations, repurchase common shares, pay cash dividends and
fund future working capital needs.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As you read the MD&A, it may be helpful to refer to information in
our consolidated financial statements, which present the results of our operations for the first quarter of fiscal 2011 and fiscal 2010. It may also be helpful to read the MD&A in our Annual Report on Form 10-K for the year ended March 31,
2010, filed with the SEC on May 28, 2010. In the MD&A, we analyze and explain the period-over-period changes in the specific line items in the Consolidated Statements of Income. Our analysis may be important to you in making decisions about
your investments in STERIS.

Financial Measures

In the following sections of the MD&A, we may, at times, refer to financial measures that are not required to be presented in the consolidated financial statements under U.S. GAAP. We sometimes use
the following financial measures in the context of this report: backlog; debt-to-total capital; net debt-to-total capital; and days sales outstanding. We define these financial measures as follows:



| |  |  | Backlog  We define backlog as the amount of unfilled capital equipment purchase orders at a point in time. We use this figure as a measure
to assist in the projection of short-term financial results and inventory requirements.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Debt-to-total capital  We define debt-to-total capital as total debt divided by the sum of total debt and shareholders equity. We
use this figure as a financial liquidity measure to gauge our ability to borrow and fund growth.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Net debt-to-total capital  We define net debt-to-total capital as total debt less cash (net debt) divided by the sum of net
debt and shareholders equity. We also use this figure as a financial liquidity measure and to measure the risk of our financial structure.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Days sales outstanding (DSO)  We define DSO as the average collection period for accounts receivable. It is calculated as net
accounts receivable divided by the trailing four quarters revenues, multiplied by 365 days. We use this figure to help gauge the quality of accounts receivable and expected time to collect.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Revenues  Defined

As required by Regulation S-X, we separately present revenues generated as either product revenues or service revenues on our Consolidated
Statements of Operations for each period presented. When we discuss revenues, we may, at times, refer to revenues summarized differently than the Regulation S-X requirements. The terminology, definitions, and applications of terms that we use to
describe revenues may be different from terms used by other companies. We use the following terms to describe revenues:



| |  |  | Revenues  Our revenues are presented net of sales returns and allowances.
| | - |  | --------------------------------------------------------------------------



| |  |  | Product Revenues  We define product revenues as revenues generated from sales of capital equipment, which includes steam sterilizers, low
temperature liquid chemical sterilant processing systems, washing systems, VHP® technology, water stills, and
pure steam generators; integrated OR; surgical lights and tables; and the consumable family of products, which includes SYSTEM
1® consumables, sterility assurance products, skin care products, and cleaning consumables.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | Service Revenues  We define service revenues as revenues generated from parts and labor associated with the maintenance, repair, and
installation of our capital equipment, as well as revenues generated from contract sterilization offered through our Isomedix segment.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Capital Revenues  We define capital revenues as revenues generated from sales of capital equipment, which includes steam sterilizers, low
temperature liquid chemical sterilant processing systems, washing systems, VHP® technology, water stills, and
pure steam generators; surgical lights and tables; and integrated OR.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Consumable Revenues  We define consumable revenues as revenues generated from sales of the consumable family of products, which includes
SYSTEM 1® consumables, sterility assurance products, skin care products, and cleaning consumables.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Recurring Revenues  We define recurring revenues as revenues generated from sales of consumable products and service revenues.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | Acquired Revenues  We define acquired revenues as base revenues generated from acquired businesses or assets and additional volumes driven
through acquired businesses or assets. We will use such measure for up to a year after acquisition.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

General Company
Overview and Executive Summary

Our mission is to provide a healthier today and safer tomorrow through knowledgeable people
and innovative infection prevention, decontamination and health science technologies, products, and services. Our dedicated employees around the world work together to supply a broad range of solutions by offering a combination of capital equipment,
consumables, and services to healthcare, pharmaceutical, industrial, and governmental Customers.

The bulk of our revenues are
derived from the healthcare and pharmaceutical industries. Much of the growth in these industries is driven by the aging of the population throughout the world, as an increasing number of individuals are entering their prime healthcare consumption
years, and is dependent upon advancement in healthcare delivery, acceptance of new technologies, government policies, and general economic conditions. In addition, each of our core industries is experiencing specific trends that could increase
demand. Within healthcare, there is increased concern regarding the level of hospital-acquired infections around the world. The pharmaceutical industry has been impacted by increased FDA scrutiny of cleaning and validation processes, mandating that
manufacturers improve their processes. In the contract sterilization industry, the aging population increases the demand for medical procedures, which increases the consumption of single use medical devices and surgical kits.

Beyond our core markets, infection-control issues are becoming a global concern, and emerging threats are prominent in the news. We are
actively pursuing new opportunities to adapt our proven technologies to meet the changing needs of the global marketplace.

During the first quarter of fiscal 2011, we recorded a pre-tax liability related to the SYSTEM 1 Rebate Program. The Rebate Program
reduced Healthcare revenues by $102.3 million, increased Healthcare cost of revenues by $7.7 million, decreased gross margin and operating margin by $110.0 million, decreased net income by $73.0 million and reduced earnings per diluted share by
$1.22. The accrual of these estimated rebates and costs increased current liabilities by $110.0 million and did not impact free cash flow during the period.

Revenues for the first quarter of fiscal 2011 were $189.0 million and gross margin percentage for the period was 9.6%. Excluding the impact of the Rebate Program, fiscal 2011 first quarter revenues were
$291.3 million compared to $283.5 million in the first quarter of fiscal 2010, representing an increase of $7.8 million, or 2.7%, driven by increases in all business segments (see subsection of MD&A titled Non-GAAP Financial Measures
for additional information and related reconciliation of non-GAAP financial measures to the most comparable GAAP measures). Excluding the impact of the Rebate Program, our adjusted gross margin percentage for the first quarter of fiscal 2011 was 44%
(see subsection of MD&A titled Non-GAAP Financial Measures for additional information and related reconciliation of non-GAAP financial measures to the most comparable GAAP measures), the same as in the first quarter of the prior
fiscal year, reflecting the impact of price increases and efficiencies, offset by lower SYSTEM 1 consumable volume and unfavorable changes in foreign exchange.

Free cash flow was $17.3 million in the first quarter of fiscal 2011 compared to $24.4 million in the prior year first quarter due to changes in operating assets and liabilities and higher capital
spending levels. Our debt-to-total capital ratio was 23.2% at June 30, 2010 and 21.8% at March 31, 2010. During the first quarter of fiscal 2011, we declared and paid quarterly cash dividends of $0.11 per common share.

Additional information regarding our fiscal 2011 first quarter financial performance is included in the subsection below titled
Results of Operations.

Matters Affecting Comparability

SYSTEM 1 Rebate Program. In April 2010, we introduced the SYSTEM 1 Rebate Program to Customers as a component of our
Transition Plan for SYSTEM 1. Generally, U.S. Customers that purchased SYSTEM 1 processors directly from us or who are current users of SYSTEM 1 and who return their units will have the option of either a pro-rated cash value or rebate toward the
future purchase of new STERIS capital equipment or consumable products. In addition, we will provide credits for SYSTEM 1 consumables in unbroken packaging and within shelf life and for the unused portion of prepaid SYSTEM 1 services contracts.

During the first quarter of fiscal 2011, we recorded a pre-tax liability related to the SYSTEM 1 Rebate Program. Of the
$110.0 million recorded, $102.3 million is attributable to the Customer Rebate portion of the Program and was recorded as a reduction to revenue, and $7.7 million is attributable to the disposal liability of the SYSTEM 1 units to be returned and was
recorded in cost of revenues.

Restructuring. During the first quarter of fiscal 2011, we did not incur any
significant additional expenses related to previously announced restructuring actions.

Additional information regarding our
restructuring actions is included in our Annual Report on Form 10-K for the year ended March 31, 2010, filed with the SEC on May 28, 2010.

International Operations. Since we conduct operations outside of the United States using various foreign currencies, our operating results are impacted by foreign currency movements relative
to the U.S. dollar. During the first quarter of fiscal 2011, our revenues were favorably impacted by $0.9 million, or 0.5%, and income before taxes was favorably impacted by $1.9 million, or 3.0%, as a result of foreign currency movements relative
to the U.S. dollar.

Non-GAAP Financial Measures

We, at times, refer to financial measures which are considered to be non-GAAP financial measures under SEC rules. We, may refer to our results of operations excluding certain transactions or
amounts that are non-recurring or are not indicative of future results, in order to provide meaningful comparisons between the periods presented.

These non-GAAP financial measures are not intended to be, and should not be, considered separately from or as an alternative to the most directly comparable GAAP financial measures.

These 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.

We believe that the presentation of these non-GAAP financial measures, when considered along with our GAAP financial measures and the reconciliation to the corresponding GAAP financial measures, provide
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.

We define free
cash flow as net cash flows provided by operating activities as presented in the Consolidated Statements of Cash Flows less purchases of property, plant, equipment, and intangibles plus proceeds from the sale of property, plant, equipment, and
intangibles, which are also presented in the Consolidated Statements of Cash Flows. We use this as a measure to gauge our ability to fund future debt principal repayments, growth outside of core operations, repurchase common shares, and pay cash
dividends. The following table summarizes the calculations of our free cash flow for the three months ended June 30, 2010 and 2009:

To supplement our financial results presented in accordance with U.S. GAAP, we have sometimes referred to
certain measures of revenues, gross profit, and the Healthcare segment results of operations in the section of MD&A titled, Results of Operations excluding the impact of the SYSTEM 1 Rebate Program. We provide adjusted measures to

Results of Operations

In the following subsections, we discuss our earnings and the factors affecting them for the first quarter of fiscal 2011 compared with the first quarter of fiscal 2010. We begin with a general overview
of our operating results and then separately discuss earnings for our operating segments.

Revenues. The
following table compares our revenues for the three months ended June 30, 2010 to the three months ended June 30, 2009:

Revenues decreased $94.6
million, or 33.4%, to $189.0 million for the quarter ended June 30, 2010, as compared to $283.5 million for the same prior year quarter. The decline reflects the $102.3 million negative impact of the Rebate Program. Adjusted revenues, excluding
the impact of the Rebate Program, increased $7.8 million, or 2.7%, to $291.3 million for the quarter ended June 30, 2010 (see subsection of MD&A titled Non-GAAP Financial Measures for additional information and related
reconciliation of non-GAAP financial measures to the most comparable GAAP measures). Capital revenues decreased $91.8 million or 99.0%. The decline reflects the $102.3 million negative impact of the Rebate Program. Adjusted capital revenues
increased $10.5 million in the first quarter of fiscal 2011 (see subsection of MD&A titled Non-GAAP Financial Measures for additional information and related reconciliation of non-GAAP financial measures to the most comparable GAAP
measures), primarily driven by higher demand in North America from Healthcare Customers. Service revenues increased $1.7 million in the first quarter of fiscal 2011 primarily due to an increase in the Isomedix segment, although these increases were
partially offset by a decrease within the Healthcare business segment. Consumable revenues decreased $4.5 million for the quarter ended June 30, 2010, primarily driven by decreases within the Healthcare segment attributable to reductions in
SYSTEM 1 consumables and lower H1N1 product sales as compared to the prior year quarter.

International revenues increased
$5.5 million, or 9.2%, to $65.2 million for the quarter ended June 30, 2010, as compared to $59.7 million for the same prior year quarter. International revenues were favorably affected by increases in capital equipment revenues, which
increased 14.4% primarily due to an increase in Healthcare revenues within Latin America. International recurring revenues increased during the first quarter of fiscal 2011 by 4.7%, reflecting an increase of 9.4% in service revenues.

United States revenues decreased $100.0 million, or 44.7%, to $123.8 million for the quarter ended June 30, 2010, as compared to
$223.8 million in the same prior year quarter. The decline reflects the $102.3 million negative impact of the Rebate Program. Adjusted United States revenues increased $2.3 million, or 1.0%, to $226.1 million for the quarter ended June 30, 2010
(see subsection of MD&A titled Non-GAAP Financial Measures for additional information and related reconciliation of non-GAAP financial measures to the most comparable GAAP measures). The increase in adjusted United States revenues
was primarily driven by an increase in Healthcare capital equipment revenues (excluding the impact of the Rebate Program) partially offset by a 23.9% decrease in Life Sciences capital equipment revenues. United States recurring revenues decreased
2.7% for the first quarter of fiscal 2011, and reflect a decrease of 7.1% in consumable revenues. The decline is primarily attributable to the decrease in SYSTEM 1 consumables.

Revenues by segment are further discussed in the section of MD&A titled, Business Segment Results of Operations.

Our gross profit is affected by the volume, pricing, and mix of sales of our products and
services, as well as the costs associated with the products and services that are sold. Gross profit percentage for the first quarter of fiscal 2011 amounted to 9.6% compared to 44.0% in the first quarter of fiscal 2010. The most significant driver
of this decline is the $110.0 million negative impact of the Rebate Program. Adjusted gross profit percentage amounted to 44.0% in the quarter and was flat compared with the prior year (see subsection of MD&A titled Non-GAAP Financial
Measures for additional information and related reconciliation of non-GAAP financial measures to the most comparable GAAP measures). Reductions in SYSTEM 1 consumables volume along with a negative foreign currency impact were offset by
productivity improvements and favorable product mix within the Life Sciences and Isomedix segments.

NM - Not meaningful.

Significant components of total selling, general, and administrative expenses (SG&A) are compensation and benefit costs, fees for professional services, travel and entertainment,
facilities costs, and other general and administrative expenses. The decrease in SG&A expense in the first quarter of fiscal 2011 reflects the benefit of cost reduction actions previously implemented as well as improved operating efficiencies.

Research and development expenses are influenced by the number and timing of in-process projects and labor hours and other
costs associated with these projects. Our research and development initiatives continue to emphasize new product development, product improvements, and the development of new technological platform innovations. During the first quarter of fiscal
2011, our investments in research and development continued to be focused on, but were not limited to, enhancing capabilities of sterile processing combination technologies, surgical tables and accessories, and the areas of emerging infectious
agents such as Prions and Nanobacteria.

In the first quarters of 2011 and 2010, we did not incur any significant additional
expenses related to our previously announced restructuring plans, and we settled certain obligations for less than originally expected. The following tables summarize our total pre-tax restructuring expenses for the first quarter of fiscal 2011 and
fiscal 2010:

Non-Operating Expenses, Net. Non-operating expense (income), net consists of
interest expense on debt, offset by interest earned on cash, cash equivalents, short-term investment balances, and other miscellaneous income. The following table compares our net non-operating expense for the three months ended June 30, 2010
and 2009:

Interest expense decreased $0.1 million during the first three months of fiscal 2011, as compared to the
same prior year period as a result of higher capitalized interest. Interest and miscellaneous income decreased $0.1 million during the first three months of fiscal 2011 compared with the same prior year period.

Income Tax Expense.The following table compares our income tax expense and effective income tax rates for operations,
excluding the impact of the Rebate Program, for the three months ended June 30, 2010 to the three months ended June 30, 2009:

|Income Tax Expense        |  | $                          | (20,636 | ) |      | $ | 14,455 |         |  | $ | (35,091 | ) |  |  | (242.8 | )%
|Effective Income Tax Rate |  |                            | 31.3    | % |      |   | 36.1   | %       |  |   |         |   |  |  |        |   

Income tax expense includes United States federal, state and local, and foreign income taxes, and
is based on reported pre-tax income. The effective income tax rates for the three-month periods ended June 30, 2010 and 2009 were 31.3% and 36.1%, respectively. Because the accrual established during the three month period ended June 30,
2010 in connection with the Rebate Program was incurred in the United States at a higher effective tax rate, a higher portion of the projected income before income taxes will be subject to taxes in jurisdictions with lower tax rates. In addition, we
benefited from the settlement of certain tax years under examination in the United States during the three-month period ended June 30, 2009 and favorable changes in our valuation allowance.

We record income tax expense during interim periods based on our estimate of the annual effective income tax rate, adjusted each quarter
for discrete items. We analyze various factors to determine the estimated annual effective income tax rate, including projections of our annual earnings and taxing jurisdictions in which the earnings will be generated, the impact of state and local
income taxes, our ability to use tax credits and net operating loss carryforwards, and available tax planning alternatives.

Business Segment Results of Operations.We operate in three reportable business segments: Healthcare, Life Sciences, and
Isomedix. Corporate and other, which is presented separately, contains the Defense and Industrial business unit plus costs that are associated with being a publicly traded company and certain other corporate costs. These costs include
executive office costs, Board of Directors compensation, shareholder services and investor relations, external audit fees, and legacy pension and post-retirement benefit costs. Our Annual Report on Form 10-K for the year ended March 31, 2010,
filed with the SEC on May 28, 2010, provides additional information regarding each business segment. The following table compares business segment revenues for the three months ended June 30, 2010 to the three months ended June 30,
2009:

Healthcare revenues decreased $96.8 million, or 48.3%, to $103.8 million for the quarter ended June 30,
2010, as compared to $200.6 million for the same prior year quarter. The primary driver of the decline was the $102.3 million negative impact of the Rebate Program. Adjusted Healthcare revenues increased $5.5 million, or 2.7%, to $206.1 million for
the quarter ended June 30, 2010 (see subsection of MD&A titled Non-GAAP Financial Measures for additional information and related reconciliation of non-GAAP financial measures to the most comparable GAAP measures), as compared
to $200.6 million for the same prior year quarter. The increase in adjusted Healthcare revenues was due to an increase in capital equipment revenues (excluding the impact of the Rebate Program) primarily because of higher demand for our products in
North America and Latin America. This increase was partially offset by declines in revenues from consumables and service of 9.4% and 1.4%, respectively. Consumable revenues decreased in all geographies, although the primary driver was lower demand
in the United States for SYSTEM 1 consumables and lower H1N1 product related sales. At June 30, 2010, the Healthcare segments backlog amounted to $134.2 million, increasing $6.4 million, or 5.0%, compared to the backlog of $127.8 million
at March 31, 2010 and increasing $1.8 million, or 1.4%, compared to the backlog of $132.4 million at June 30, 2009. The increase is driven by demand for new products.

Life Sciences revenues increased $0.5 million, or 1.1%, to $46.6 million for the quarter ended June 30, 2010, as compared to $46.1
million for the same prior year quarter. The increase in Life Sciences revenues was driven by increases of 12.7% and 4.1% in consumables and service revenues, respectively. The decline in capital equipment revenues occurred primarily in North
America, which continues to be impacted by consolidations within the industry limiting the order levels from our pharmaceutical Customers. At June 30, 2010, the Life Sciences segments backlog amounted to $37.9 million, decreasing $3.9
million, or 9.3% compared to the backlog of $41.8 million at March 31, 2010 and decreasing $8.3 million, or 18.0%, compared to the backlog of $46.3 million at June 30, 2009.

Isomedix revenues increased $2.3 million, or 6.4%, to $37.7 million for the quarter ended June 30, 2010, as compared to $35.4

Segment operating income is calculated as the segments gross profit less direct expenses and indirect
cost allocations, which results in the full allocation of all distribution and research and development expenses, and the partial allocation of corporate costs. Corporate cost allocations are based on each segments percentage of revenues,
headcount, or other variables in relation to those of the total Company. In addition, the Healthcare segment is responsible for the management of all but one manufacturing facility and uses standard cost to sell products to the Life Sciences
segment. Corporate and other includes the gross profit and direct expenses of the Defense and Industrial business unit, as well as

certain unallocated corporate costs related to being a publicly traded company and legacy pension and post-retirement benefits, as previously discussed.

The Healthcare segments operating loss was $77.9 million for the first quarter of fiscal 2011 compared to $32.1 million for the
first quarter of fiscal 2010. The loss is attributable to the $110.0 million negative impact of the Rebate Program. Adjusted Healthcare operating income was $32.1 for the three months ended June 30, 2010 (see subsection of MD&A titled
Non-GAAP Financial Measures for additional information and related reconciliation of non-GAAP financial measures to the most comparable GAAP measures). Adjusted operating income was flat compared with the prior year. The segments
operating margin, excluding the impact of the Rebate Program, declined relative to the prior year period primarily due to reductions in SYSTEM 1 consumables volume.

The Life Sciences segments operating income increased to $6.3 million for the quarter ended June 30, 2010 from $4.8 million for the quarter ended June 30, 2009. The segments
operating margins were 13.5% and 10.4% for the quarters ended June 30, 2010 and 2009, respectively. The improvement in operating performance was primarily driven by product mix and efficiency initiatives.

The Isomedix segments operating income increased $2.2 million, or 26.9%, to $10.6 million for the first quarter of fiscal 2011 as
compared to $8.3 million for the same prior year period. The segments operating margins were 28.1% and 23.6% for the quarters ended June 30, 2010 and 2009, respectively, due to increased revenues.

Net Cash
Provided by Operating Activities.The net cash provided by our operating activities was $29.7 million for the first three months of fiscal 2011 compared to $32.6 million for the first three months of fiscal 2010. The following discussion
summarizes the significant changes in our operating cash flows:



| |  |  | Non-cash items - Our non-cash items include depreciation, depletion and amortization, share-based compensation expense, changes in deferred income
taxes, and other items. Changes in our non-cash items used cash of $28.5 million for the first three months of fiscal 2011 and provided cash of $11.6 million for the first three months of fiscal 2010. Significant changes in these items for the first
quarter of fiscal 2011 as compared to the same prior year period are summarized below:

##### Table of Contents

| |  |  | Depreciation, depletion, and amortization - Depreciation, depletion, and amortization is a significant component of non-cash items. This expense
totaled $13.0 million and $13.9 million for the first three months of fiscal 2011 and fiscal 2010, respectively.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Deferred income taxes - Our deferred income tax benefit was $44.5 million for the first three months of fiscal 2011, compared with a deferred income
tax benefit of $4.4 million for the first three months of fiscal 2010. The increase is attributable to the recognition of a deferred tax asset in connection with the recording of the SYSTEM 1 Rebate Program accrual.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Share-based compensation expense - We recorded share-based compensation expense of $3.9 million and $2.0 million for the first three months of fiscal
2011 and fiscal 2010, respectively.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Changes in operating assets and liabilities - Changes to our operating assets and liabilities, including the change in Accrued System 1 Rebate Program,
provided cash of $103.4 million and used cash of $4.5 million during the first quarters of fiscal 2011 and fiscal 2010, respectively.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Accounts receivable, net - Changes in our net accounts receivable balances provided cash of $25.8 million and $38.3 million during the first three
months of fiscal 2011 and fiscal 2010, respectively. Our accounts receivable balances may change from period to period due to the timing of revenues and Customer payments.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Inventories, net - Increases in our net inventory balances drove uses of cash of $14.2 million and $1.9 million during the first three months of fiscal
2011 and fiscal 2010, respectively. The increase resulted from a higher level of inventory due to higher production volume levels and new product inventory.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Other current assets - Our other current assets primarily consist of prepaid expenses for insurance, taxes, and other general corporate items. Changes
in other current asset balances provided cash of $3.0 million and $5.5 million during the first three months of fiscal 2011 and 2010, respectively.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Accounts payable - Decreases in our accounts payable balances drove uses of cash of $1.1 million and $18.5 million during the first three months of
fiscal 2011 and fiscal 2010, respectively. Cash flows related to accounts payable may change from period to period due to varying payment due dates and other terms of our accounts payable obligations.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Accrued SYSTEM 1 Rebate Program - The increase results from the establishment of the accrual of $110.0 million for liabilities resulting from the
SYSTEM 1 Rebate Program.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Accruals and other, net - Changes in our net accruals and other liabilities balances used cash of $20.1 million and $27.8 million during the first
three months of fiscal 2011 and fiscal 2010, respectively. Cash flows related to our accruals and other liabilities balances may change from period to period primarily due to the timing of accruals and payments under our incentive compensation
programs. Accruals under our various incentive compensation programs rise during the course of the fiscal year and decline significantly in the first fiscal quarter as payments are made under these programs. Changes in accruals for deferred revenues
also contribute to the increase or decrease in these balances.

Net Cash Used In Investing
Activities - The net cash we used in investing activities totaled $12.4 million for the first three months of fiscal 2011 compared with $8.2 million for the first three months of fiscal 2010. The following discussion summarizes the
significant changes in our investing cash flows for the first three months of fiscal 2011 and fiscal 2010:



| |  |  | Purchases of property, plant, equipment, and intangibles, net - Capital expenditures increased $4.0 million to $12.4 million during the first three
months of fiscal 2011 as compared to $8.4 million during the same prior year period. Radioisotope purchases were higher during the first three months of fiscal 2011 in comparison to fiscal 2010.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Net Cash Used In Financing Activities - The net cash used in financing activities amounted to $3.7 million for the first
three months of fiscal 2011 compared with net cash used in financing activities of $6.2 million for the first three months of fiscal 2010. The following discussion summarizes the significant changes in our financing cash flows for the first three
months of fiscal 2011 and fiscal 2010:



| |  |  | Repurchases of common shares - The Companys Board of Directors has provided authorization to repurchase the Companys common shares. During
the first three months of fiscal 2011 and fiscal 2010, we did not repurchase any common shares.

| |  |  | Cash dividends paid to common shareholders - During the first three months of fiscal 2011, we paid total cash dividends of $6.5 million, or $0.11 per
outstanding common share. During the first three months of fiscal 2010, we paid total cash dividends of $6.4 million, or $0.11 per outstanding common share.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Stock option and other equity transactions, net - We receive cash for issuing common shares under our various employee stock compensation programs.
During the first three months of fiscal 2011 and fiscal 2010, we received cash proceeds totaling $2.2 million and $0.2 million, respectively, under these programs.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Tax benefit from stock options exercised - During the first three months of fiscal 2011, our income taxes were reduced by $0.7 million as a result of
deductions allowed for stock options exercised. The reduction in the fiscal 2010 comparable period was less than $0.1 million.

Cash Flow Measures.Free cash flow was $17.3 million in the first quarter of fiscal 2011 compared to $24.4 million in the prior year first quarter due to changes in operating assets and
liabilities and higher capital spending levels. Our debt-to-total capital ratio was 23.2% at June 30, 2010 and 21.8% at March 31, 2010.

Sources of Credit and Contractual and Commercial Commitments.Information related to our sources of credit and contractual and commercial commitments is included in our Annual Report on Form
10-K for the year ended March 31, 2010, filed with the SEC on May 28, 2010. Our commercial commitments were approximately $39.4 million at June 30, 2010 reflecting a net increase of $2.7 million in surety bonds and other commercial
commitments from March 31, 2010. In conjunction with facility consolidation projects, we have entered into commitments aggregating approximately $8.1 million with general contractors as of June 30, 2010. These obligations are comprised
principally of construction contracts and are generally due within 24 months. The related construction costs are incurred and financed through operating cash flow. The maximum aggregate borrowing limits under our revolving credit facility
(Facility) have not changed since March 31, 2010. At June 30, 2010, there was $375.8 million available under the Facility for borrowing. The maximum aggregate borrowing limit of $400.0 million under the Facility is reduced by
outstanding borrowings and letters of credit issued under a sub-limit within the Facility ($24.2 million at June 30, 2010).

Cash Requirements.Currently, we intend to use our existing cash and cash equivalent balances, cash generated from operations, and our existing credit facilities for short-term and long-term
capital expenditures and our other liquidity needs. We believe that these amounts will be sufficient to meet working capital needs, capital requirements, and commitments for at least the next twelve months. However, our capital requirements will
depend on many uncertain factors, including our rate of sales growth, our Customers acceptance of our products and services, the costs of obtaining adequate manufacturing capacities, the timing and extent of our research and development
projects, and changes in our operating expenses. To the extent that our existing sources of cash are not sufficient to fund our future activities, we may need to raise additional funds through additional borrowings or selling equity securities. We
cannot assure you that we will be able to obtain additional funds on terms favorable to us, or at all.

Critical Accounting Policies,
Estimates, and Assumptions

Information related to our critical accounting policies, estimates, and assumptions is included
in our Annual Report on Form 10-K for the year ended March 31, 2010, filed with the SEC on May 28, 2010. Our critical accounting policies, estimates, and assumptions have not changed materially from March 31, 2010.

SYSTEM 1 Rebate Program

In April 2010, we introduced the Rebate Program to Customers as a component of our transition plan for SYSTEM 1. Generally, U.S. Customers
that purchased SYSTEM 1 processors directly from us or who are current users of SYSTEM 1 and who return their units have the option of either a pro-rated cash value or rebate toward the future purchase of new STERIS capital equipment or consumable
products. In addition, we will provide credits for SYSTEM 1 consumables in unbroken packaging and within shelf life and for the unused portion of prepaid SYSTEM 1 service contracts.

Recording the obligations associated with the Rebate Program requires the use of estimates and assumptions. The use of estimates and
assumptions involves judgments with respect to factors that may impact the ultimate outcome and may be beyond managements control. The amount recognized during the first quarter of fiscal 2011 is based upon the quantity of SYSTEM 1 processors
eligible for rebates and the estimated value of rebates to be provided upon their return. Rebates of $102.3 million are recognized as contra-revenue consistent with other returns and allowances offered to Customers. The estimated cost of $7.7
million to facilitate the disposal of the processors has been recognized as cost of revenues. Both components are recorded as current liabilities. No rebate obligations were settled during the three months ended June 30, 2010. The key
assumptions involved in the estimates associated with the Rebate Program include: the number and age of

SYSTEM 1 processors eligible for rebates under the program, the number of Customers that will elect to participate in the Rebate Program, the proportion of Customers that will choose each rebate
option, and the estimated per unit costs of disposal.

The number and age of SYSTEM 1 processors has been estimated based on
our historical sales and service records and we have assumed that 100% of these Customers will elect to participate in the Rebate Program. In order to estimate the portion of Customers that will choose each available rebate option, we first assessed
recent trends in sales of the proprietary consumable products utilized in the SYSTEM 1 processor. The 19% decline in shipments during the approximately seven month period ended June 30, 2010 indicates that a portion of our Customers have
already transitioned away from the SYSTEM 1 technology. The remaining 81%, provides the best available indication of the portion of Customers likely to elect the rebate for the SYSTEM 1E processor. Order and quote data from the fiscal 2011 first
quarter provided indications of the proportion of Customers that are expected to choose each of the other cash and rebate allowance options. The per unit costs associated with disposal were estimated based on the service hours involved and quotes
from our vendors which are based on current freight and disposal contracts.

Our assumptions regarding the response of our
Customers to the Rebate Program could be wrong and actual results could be different from these estimates. For example, if all Customers elected the maximum incentive rebate associated with the SYSTEM 1E processor rebate, the total estimated rebate
liability of $102.3 million would increase to approximately $111.0 million. Conversely, if all Customers elected the cash rebate option, the total estimated rebate liability would decrease to approximately $52.0 million.

Contingencies

We are
involved in various patent, product liability, consumer, commercial, environmental, tax proceedings and claims, governmental investigations, and other legal and regulatory proceedings that arise from time to time in the course of our business. We
record a liability for such contingencies to the extent that we conclude that their occurrence is both probable and estimable. We consider many factors in making these assessments, including the professional judgment of experienced members of
management and our legal counsel. We have made estimates as to the likelihood of unfavorable outcomes and the amounts of such potential losses. In our opinion, the ultimate outcome of these proceedings and of claims that are probable and estimable
is not anticipated to have a material adverse affect on our consolidated financial position, results of operations, or cash flows. However, the ultimate outcome of claims, litigation, and other proceedings is unpredictable and actual results could
be materially different from our estimates. We record anticipated recoveries under applicable insurance contracts when assured of recovery. Refer to Part II, Item 1, Legal Proceedings for additional information.

We are subject to taxation from United States federal, state, and local, and foreign jurisdictions. Tax positions are settled primarily
through the completion of audits within each individual tax jurisdiction or the closing of a statute of limitation. Changes in applicable tax law or other events may also require us to revise past estimates. The IRS routinely conducts audits of our
federal income tax returns. In the first quarter of fiscal 2009, we reached a settlement with the IRS on all material tax matters for fiscal 2002 through fiscal 2005. In the second quarter of fiscal 2010, we reached a settlement with the IRS on all
material tax matters for fiscal 2006 through fiscal 2007. The IRS also began its audit of fiscal 2008 and fiscal 2009 in fiscal 2010. We remain subject to tax authority audits in various other jurisdictions in which we operate. If we prevail in
matters for which accruals have been recorded, or are required to pay amounts in excess of recorded accruals, our effective income tax rate in a given financial statement period could be materially impacted.

Additional information regarding our commitments and contingencies is included in note 10 to our consolidated financial statements
titled, Contingencies.

International Operations

Since we conduct operations outside the United States using various foreign currencies, our operating results are impacted by foreign currency movements relative to the U.S. dollar. During the first
quarter of fiscal 2011, our revenues were favorably impacted by 0.9 million, or 0.5%, and income before income taxes was favorably impacted by $1.9 million, or 3.0%, as a result of foreign currency movements relative to the U.S. dollar. We
cannot predict future changes in foreign currency exchange rates or the effect they will have on our operations.
