NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Unless the context requires otherwise, “we”, “us” or “our” refers to Stericycle, Inc. and its subsidiaries on a consolidated basis.

NOTE 1 – BASIS OF PRESENTATION

The accompanying condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. However, the Company believes the disclosures included in the accompanying condensed consolidated financial statements are adequate to make the information presented not misleading. In our opinion, all adjustments necessary for a fair presentation for the periods presented have been reflected and are of a normal recurring nature. These condensed consolidated financial statements should be read in conjunction with the Stericycle, Inc. and Subsidiaries Consolidated Financial Statements and notes thereto for the year ended December 31, 2011, as filed with our Annual Report on Form 10-K for the year ended December 31, 2011. The results of operations for the nine months ended September 30, 2012 are not necessarily indicative of the results that may be achieved for the entire year ending December 31, 2012.

There were no material changes in the Company’s critical accounting policies since the filing of its 2011 Form 10-K. As discussed in the 2011 Form 10-K, the preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make certain estimates and assumptions that affect the amount of reported assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and revenues and expenses during the periods reported. Actual results may differ from those estimates.

Certain amounts in previously issued financial statements have been reclassified to conform to the current period presentation.

For financial reporting purposes, our 2012 and 2011 acquisitions were accounted for using the acquisition method of accounting. These acquisitions resulted in recognition of goodwill in our financial statements reflecting the premium paid to acquire businesses that we believe are complementary to our existing operations and fit our strategy. During the nine months ended September 30, 2012, we recognized a net increase in goodwill of $87.4 million excluding the effect of foreign currency translation (see Note 10 – Goodwill and Other Intangible Assets, in the Notes to the Condensed Consolidated Financial Statements). A net of $55.8 million was assigned to our United States reporting segment, and $31.6 million was assigned to our International reporting segment. Approximately $56.7 million of the goodwill recognized during the nine months ended September 30, 2012 will be deductible for income taxes.

During the nine months ended September 30, 2012, we recognized a net increase in intangible assets of $98.7 million excluding the effect of foreign currency translation. The changes include $72.5 million in the estimated fair value of acquired customer relationships with amortizable lives of 15-40 years, $23.4 million in permits with indefinite lives, $2.7 million in a tradename with an amortizable life of 15 years, and $0.1 million in other intangible asset with amortizable life of 10 years.

The purchase prices for these acquisitions in excess of acquired tangible assets have been primarily allocated to goodwill and other intangibles and are preliminary pending completion of certain intangible asset valuations and completion accounts. The following table summarizes the preliminary purchase price allocation for current period acquisitions and other adjustments to purchase price allocations during the nine months ended September 30, 2012:

In thousands
Fixed assets	$	21,572
Intangibles		98,706
Goodwill		87,410
Net other assets/ (liabilities)		12,703
Debt		(3,348	)
Net deferred tax liabilities		(17,002	)
Noncontrolling interests		15,611
Total purchase price allocation	$	215,652

During the nine months ended September 30, 2012 and 2011, the Company incurred $6.2 million and $14.4 million, respectively, of acquisition related expenses. These expenses are included with SG&A on our Condensed Consolidated Statements of Income and Comprehensive Income.

In July 2012, we were required by the United Kingdom Competition Committee to divest a business acquired in 2011. The sale price of the business was $0.7 million and resulted in a pretax loss of $4.9 million which is included in “Selling, general and administrative expenses” (“SG&A”). The following table summarizes the assets sold:

NOTE 3 – NEW ACCOUNTING STANDARDS

Accounting Standards Recently Adopted

Other Comprehensive Income

On January 1, 2012, Stericycle adopted changes issued by the Financial Accounting Standards Board (“FASB”) to guidance on the presentation of comprehensive income. These changes give an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements; the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity was eliminated. The items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income were not changed. Additionally, no changes were made to the calculation and presentation of earnings per share. Part of the adopted standard related to presentation of reclassification of items out of accumulated other comprehensive income have been deferred. Other than the change in presentation, these changes did not have an impact on our financial statements.

Goodwill Impairment Testing

On January 1, 2012, Stericycle adopted changes issued by the FASB to guidance on the testing for impairment of goodwill. Previous guidance required an entity to test goodwill for impairment, on at least an annual basis, by comparing the fair value of a reporting unit with its carrying amount, including goodwill (step one). If the fair value of a reporting unit is less than its carrying amount, then the second step of the test must be performed to measure the amount of the impairment loss, if any. Under the amendments, an entity has the option to use a qualitative assessment, that it is more likely than not (greater than 50%) that the fair value of goodwill is less than its carrying amount. We performed our annual test for goodwill impairment during the second quarter and chose to perform a quantitative assessment.

Fair Value Measurement

On January 1, 2012, Stericycle adopted changes issued by the FASB for additional disclosures concerning the valuation processes used and sensitivity of the fair value measurement to changes in unobservable inputs for those items categorized as Level 3, a reporting entity’s use of a nonfinancial asset in a way that differs from the asset’s highest and best use, and the categorization by level in the fair value hierarchy for items required to be measured at fair value for disclosure purposes only. Other than the change in presentation, these changes did not have an impact on our financial statements.

8

Accounting Standards Issued But Not Yet Adopted

Testing Indefinite-Lived Intangible Assets for Impairment

On July 27, 2012 the FASB issued guidance allowing a company to perform a qualitative assessment in determining whether an indefinite lived intangible asset is impaired. This new guidance is similar to the previously issued guidance allowing a qualitative assessment when performing annual goodwill impairment testing. The guidance also changes when a company should perform an interim period test for impairment, allowing for positive evidence to offset negative evidence when determining whether an interim impairment test is required. The new guidance should not affect the ultimate outcome of an impairment test; therefore there will be no impact on our financial statements. The effective date of this guidance for our Company is January 1, 2013; however, the guidance allows for early adoption. We are currently evaluating whether we will early adopt this guidance. We perform our annual test for impairment for indefinite lived intangibles in the fourth quarter.

NOTE 4 – FAIR VALUE MEASUREMENTS

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

Level 1 – Quoted prices in active markets for identical assets or liabilities.

Level 2 – Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.

We recorded a $0.5 million asset related to the fair value of a treasury lock hedge. The treasury lock hedge locked in the interest rate on the issuance of expected private placement debt and was used to eliminate interest rate risk. The fair value of the hedge was calculated by taking the present value of the difference between the locked rate and treasury rates at September 30, 2012. The hedge will terminate in October 2012 at which time the settlement amount, net of tax, will be recognized in accumulated other comprehensive income and amortized to net interest expense over the life of the underlying debt.

We had contingent consideration liabilities recorded in the amounts of $22.9 million, of which $14.0 million is current, at September 30, 2012, and $9.9 million at December 31, 2011 using Level 3 inputs. Contingent consideration represents amounts to be paid as part of acquisition consideration only if certain future events occur. These events are usually acquisition targets for revenues or earnings. We arrive at the fair value of contingent consideration by applying a weighted probability of potential outcomes to the maximum possible payout. The calculation of these potential outcomes is dependent on both past financial performance and management assumptions about future performance. If the financial performance measures were all fully met, our maximum liability would be $24.9 million. Contingent consideration liabilities are reassessed each quarter and are reflected in the condensed consolidated balance sheets as part of “Other current liabilities” or “Other liabilities”. Changes to contingent consideration are reflected in the table below:

Fair Value of Debt: At September 30, 2012, the fair value of the Company’s debt obligations was estimated, using Level 2 inputs, at $1.34 billion compared to a carrying amount of $1.30 billion. At December 31, 2011, the fair value of the Company’s debt obligations was estimated, using Level 2 inputs, at $1.41 billion compared to a carrying amount of $1.38 billion. The fair values were estimated using market interest rates for comparable instruments. The Company has no current plans to retire a significant amount of its debt prior to maturity.

There were no movements of items between fair value hierarchies.

NOTE 5 – INCOME TAXES

We and our subsidiaries file U.S. federal income tax returns and income tax returns in various states and foreign jurisdictions.

The Company has recorded accruals to cover uncertain tax positions taken on previously filed tax returns. Such liabilities relate to additional taxes, interest and penalties the Company may be required to pay in various tax jurisdictions. During the course of examinations by various taxing authorities, proposed adjustments may be asserted. The Company evaluates such items on a case-by-case basis and adjusts the accrual for uncertain tax positions. During the quarter ended September 30, 2012 we had immaterial net decreases to our accruals related to a reassessment of previous and current uncertain tax positions.

NOTE 6 – STOCK BASED COMPENSATION

At September 30, 2012 we had the following stock option and stock purchase plans:

• the 2011 Incentive Stock Plan, which our stockholders approved in May 2011;

• the 2008 Incentive Stock Plan, which our stockholders approved in May 2008;

• the 2005 Incentive Stock Plan, which our stockholders approved in April 2005;

• the 2000 Nonstatutory Stock Option Plan, which expired in February 2010;

The Black-Scholes option-pricing model is used in determining the fair value of each option grant. The expected term of options granted is based on historical experience. Expected volatility is based upon historical volatility. The expected dividend yield is zero. The risk-free interest rate is based upon the U.S. Treasury yield rates for a comparable period. The assumptions that we used in the Black-Scholes model are as follows:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2012			2011			2012			2011
Expected term (in years)		6.00			5.75			6.00			5.75

NOTE 10 – GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill and identifiable indefinite lived intangible assets are not amortized, but are subject to an annual impairment test. Other intangible assets are amortized over their useful lives. We have determined that our customer relationships have useful lives from 14 to 40 years based upon the type of customer, with a weighted average remaining useful life of 30.0 years. We have covenants not-to-compete intangibles with useful lives from 4 to 14 years, with a weighted average remaining useful life of 4.8 years. We have tradename intangibles with useful lives from 15 to 40 years, with a weighted average remaining useful life of 16.8 years. We have determined that our permits have indefinite lives due to our ability to renew these permits with minimal additional cost, and therefore they are not amortized.

We have two geographical reporting segments, “United States” and “International”, both of which have goodwill. The changes in the carrying amount of goodwill since December 31, 2010, by reportable segment, were as follows:

In thousands
	United States			International			Total
Balance as of December 31, 2010	$	1,279,758		$	316,006		$	1,595,764

Balance as of September 30, 2012	$	1,562,199		$	443,499		$	2,005,698

Current year adjustments to goodwill for 2011 acquisitions are primarily due to the finalization of intangible asset valuations.

As of September 30, 2012 and December 31, 2011, the values of the intangible assets were as follows:

In thousands

During the quarters ended September 30, 2012 and 2011, the aggregate amortization expense was $5.6 million and $4.2 million, respectively. For the nine months ended September 30, 2012 and 2011, the aggregate amortization expense was $15.7 million and $11.1 million, respectively.

The estimated amortization expense for each of the next five years, assuming no additional amortizable intangible assets, is as follows for the years ended December 31:

In thousands
2012	$	21,213
2013		22,924
2014		22,767
2015		22,444
2016		22,307

Future amortization expense may fluctuate depending on changes in foreign currency rates, future acquisitions, or changes to the estimated amortizable life of the intangibles. The estimates for amortization expense noted above are based upon foreign exchange rates as of September 30, 2012.

During the quarter ended June 30, 2012, we performed our annual goodwill impairment evaluation for our three reporting units, Domestic Regulated Waste, Domestic Regulated Returns and Recall Management Services, and International. We calculated fair value for our reporting units using two methods, one a market approach and the other an income approach. Both the market and income approaches indicated no impairment to goodwill to any of our three reporting units.

Market Approach: Our market approach begins by calculating the market capitalization of the Company using the average stock price for the prior 30 days and the outstanding share count at June 30, 2012. We then look at the Company’s Earnings Before Interest, Tax, Depreciation, and Amortization (“EBITDA”), adjusted for stock compensation expense and other items, such as change in fair value of contingent consideration, restructuring costs and plant closure expenses, for the prior twelve months. The calculated market capitalization is divided by the modified EBITDA to arrive at a valuation multiple. The fair value of each reporting unit is then calculated by taking the product of the valuation multiple and the trailing twelve month modified EBITDA of that reporting unit. The fair value was then compared to the reporting units’ book value and determined to be in excess of the book value. We believe that starting with the fair value of the company as a whole is a reasonable measure as that fair value is then allocated to each reporting unit based on that reporting unit’s individual earnings. A sustained drop in our stock price would have a negative impact to our fair value calculations. A temporary drop in earnings of a reporting unit would have a negative impact to our fair value calculations.

16

The results of our goodwill impairment test using the market approach indicated the fair value of our reporting units exceeded book value by a substantial amount, in excess of 100% of book value.

Income Approach: The income approach uses expected future cash flows of each reporting unit and discounts those cash flows to present values. Expected future cash flows are calculated using management assumptions of internal growth, capital expenditures, and cost efficiencies. Future acquisitions are not included in the expected future cash flows. We use a discount rate based on our Company calculated weighted average cost of capital which is adjusted for each of our reporting units based on size risk premium and country risk premium. Significant assumptions used in the income approach include realization of future cash flows and the discount rate used to present value those cash flows.

The results of our goodwill impairment test using the income approach indicated the fair value of our reporting units exceeded book value by a substantial amount; in excess of 100%.

We perform our annual impairment analysis of our indefinite lived intangibles (facility permits) during the quarter ended December 31 of each year.

and other covenants and restrictions, including a restriction on dividend payments. The financial debt covenants are the same for the senior credit facility and the private placement notes. At September 30, 2012, we were in compliance with all of our financial debt covenants.

As of September 30, 2012 and December 31, 2011, we had $158.4 million and $159.1 million, respectively, committed to outstanding letters of credit under our senior credit facility. The unused portion of the revolving credit facility as of September 30, 2012 and December 31, 2011 was $609.8 million and $313.0 million, respectively.

As of September 30, 2012 we had $200.0 million outstanding under a short term loan agreement. Proceeds from the Term Loan were used to pay down our senior credit facility. This loan matures in December 2012.

Guarantees

We have guaranteed a loan to JPMorganChase Bank N.A. on behalf of Shiraishi-Sogyo Co. Ltd (“Shiraishi”). Shiraishi is a customer in Japan that is expanding its medical waste management business and has a one year loan with a current balance of $6.3 million with JPMorganChase Bank N.A. that matures on May 31, 2013. We also have extended loans to Shiraishi for $15.4 million in support of its medical waste business. These amounts are collateralized with the assets of Shiraishi and related companies.

NOTE 12 – GEOGRAPHIC INFORMATION

There were no material changes in the Company’s critical accounting policies since the filing of its 2011 Form 10-K. As discussed in the 2011 Form 10-K, the preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make certain estimates and assumptions that affect the amount of reported assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and revenues and expenses during the periods reported. Actual results may differ from those estimates.

Revenues: Our revenues increased $59.5 million, or 14.2%, in the third quarter of 2012 to $480.5 million from $420.9 million in the same period in 2011. Domestic revenues increased $44.3 million, or 14.6%, to $348.2 million from $303.9 million in the same period in 2011. Internal revenue growth for domestic small account customers increased by $19.2 million, or approximately 11%, and internal revenue growth for large quantity customers increased by $9.6 million, or approximately 9%. Internal revenues for returns and recall management services increased by $3.0 million in 2012. Internal revenues excludes acquisitions less than one year old. Total regulated waste and returns management domestic acquisitions less than one year old contributed approximately $12.5 million to the increase in revenues.

International revenues increased $15.2 million, or 13.0%, to $132.3 million from $117.1 million in the same period in 2011. Internal growth in the international segment contributed $4.2 million in increased revenues, or approximately 4%. Internal growth

21

excludes the effect of foreign exchange and acquisitions and divestitures less than one year old. The effect of exchange rate fluctuations unfavorably impacted international revenues approximately $8.0 million while acquisitions net of divestitures less than one year old contributed an additional $19.0 million in international revenues.

Cost of Revenues: Our cost of revenues increased $34.1 million, or 14.8%, in the third quarter of 2012 to $264.9 million from $230.9 million in the same period in 2011. Our domestic cost of revenues increased $24.3 million, or 15.8%, in the third quarter of 2012 to $178.0 million from $153.7 million in the same period in 2011 as a result of costs related to a proportional increase in revenues from acquisitions and internal growth.

Our international cost of revenues increased $9.8 million, or 12.7%, in the third quarter of 2012 to $87.0 million from $77.2 million in the same period in 2011 as a result of costs related to proportional increase in revenues from acquisitions and internal growth and partially impacted by changes in exchange rates.

Our consolidated gross margin percentage decreased to 44.9% during the third quarter of 2012 from 45.2% during the same period in 2011 primarily due to lower margins on newly acquired revenues offset partially by improvements in the base business margins.

Selling, General and Administrative Expenses: Excluding the effect of acquisition and integration expenses, restructuring costs, loss on sale of business, and other items (“Acquisition-related Items”), selling, general and administrative (“SG&A”) expenses increased approximately $11.1 million, or 14.1%, in the third quarter of 2012 to $90.2 million from $79.1 million in the same period in 2011 primarily as investment spending supported the increase in revenues and acquired SG&A expenses. As a percentage of revenue, these costs remained at 18.8% for the third quarter 2012 and 2011.

Domestically, third quarter SG&A expenses, excluding Acquisition-related Items, increased $7.5 million, or 12.9%, to $65.6 million from $58.1 million in the same period in 2011. As percentage of revenues, SG&A was lower at 18.9% in the third quarter of 2012 compared to 19.1% in 2011. As a percentage of revenues, amortization expense of acquired intangible assets increased by 0.1%.

Internationally, third quarter SG&A expenses, excluding Acquisition-related Items, increased $3.6 million, or 17.1%, to $24.6 million from $21.0 million in the same period in 2011. As a percentage of revenues, these costs were 18.6% in 2012 compared to 17.9% in 2011. The increase in SG&A was primarily due to the increased number of international acquisitions partially offset by cost savings from the restructuring of the international management structure and the continued integration of acquisitions. SG&A expense excluding Acquisition-related Items, as a percentage to revenue, was up due to a higher ratio of amortization expense to revenues and the inclusion of stock compensation expense.

Income from Operations: Income from operations increased $10.0 million, or 9.5%, in the third quarter of 2012 to $114.5 million from $104.6 million in same period in 2011. During the quarter ended September 2012, we recognized $2.5 million in

22

acquisition expenses, $1.2 million of expense related to the integration of new acquisitions, $2.3 million of restructuring expenses, and a $4.9 million loss related to a divestiture in the United Kingdom.

During the quarter ended September 2011, we recognized $3.2 million in acquisition expenses, $1.8 million related to the integration of new acquisitions, $0.6 million of restructuring costs, $0.5 million in litigation settlement, and $0.3 million loss related to a divestiture in Mexico.

Net Interest Expense: Net interest expense increased to $12.9 million during the third quarter in 2012 from $11.8 million during the same period in 2011. Our interest expense was higher in the third quarter of 2012 due primarily to a higher interest rate from the renewal of our senior credit facility in September 2011.

Income Tax Expense: Income tax expense increased to $35.4 million in the third quarter of 2012 from $32.4 million in the same period in 2011. The tax rates for the quarters ended September 30, 2012 and 2011 were 35.0% and 35.2%, respectively.

Revenues: Our revenues increased $180.0 million, or 14.6%, for the nine months ended September 30, 2012 to $1.41 billion from $1.23 billion in same period in 2011. Domestic revenues increased $120.0 million, or 13.4%, to $1.02 billion from $895.2 million in 2011 as internal revenue growth for domestic small account customers increased by $52.1 million, or approximately 10%, and internal revenue growth for large quantity customers increased by $24.7 million, or approximately 8%. Internal revenues for returns and recall management services decreased by $0.2 million. Internal revenues exclude acquisitions less than one year old. Total domestic regulated waste and returns management acquisitions less than one year old contributed approximately $43.4 million to the increase in domestic revenues.

International revenues increased $60.0 million, or 17.9%, to $394.3 million in 2012 from $334.3 million in 2011. Internal growth in the international segment contributed $13.8 million, or approximately 4%, in increased revenues. Internal growth excludes the effect of foreign exchange and acquisitions and divestitures less than one year old. The effect of exchange rate fluctuations unfavorably impacted international revenues approximately $19.5 million and acquisitions and divestitures less than one year old contributed an additional $65.7 million to international revenues.

Cost of Revenues: Our cost of revenues increased $108.9 million, or 16.2%, for the nine months ended September 30, 2012 to $779.2 million from $670.3 million during the same period in 2011. Our domestic cost of revenues increased $67.5 million, or 14.9%, to $520.1 million from $452.6 million in the same period in 2011 as a result of costs related to a proportional increase in revenues from acquisitions and internal growth.

Our international cost of revenues increased $41.4 million, or 19.0%, to $259.1 million from $217.7 million in same period in 2011 as a result of costs related to proportional increase in revenues from acquisitions and partially driven by the impact of exchange rates.

Our consolidated gross margin percentage decreased to 44.7% during 2012 from 45.5% during 2011 due to lower margins on newly acquired revenues offset partially by improvements in the base business margins.

Selling, General and Administrative Expenses: Excluding Acquisition-related Items, SG&A expenses increased $30.8 million, or 13.3%, in the nine months ended September 30, 2012 to $263.2 million from $232.4 million in the same period in 2011. As a percentage of revenue, these costs decreased by 0.2% for the nine months ended September 30, 2012 compared to the same period in 2011.

24

Domestically, SG&A, excluding Acquisition-related Items, increased $16.4 million in 2012, or 9.5%, to $189.9 million from $173.5 million in the same period in 2011. The increase was primarily due to SG&A expenses related to the acquired revenues, higher amortization, market penetration for our Sharps Management and Pharmaceutical Waste programs, investment in the Steri-Safe services, and compliance related services.

Internationally, SG&A, excluding Acquisition-related Items, increased $14.4 million in 2012, or 24.4%, to $73.3 million from $58.9 million in the same period in 2011. As a percentage of revenues, these costs were 18.6% in 2012 and 17.6% in 2011. The increase in SG&A was due to the increased number of international acquisitions partially offset by restructuring of the international management structure and the continued integration of acquisitions. SG&A expense, as a percentage of revenue, was up due to a higher ratio of amortization expense to revenues and the inclusion of stock compensation expense.

Income from Operations: Income from operations increased $39.6 million, or 12.8%, in the nine months ended September 30, 2012 to $348.5 million from $308.9 million in the same period in 2011. During the nine months ended September 30, 2012, we recognized $6.2 million in acquisition expenses, $3.5 million related to the integration of new acquisitions, $3.4 million of restructuring and plant closure costs, $4.9 million loss related to the U.K. divestiture, and $0.6 million of expense related to a change in fair value of contingent consideration.

During the nine months ended September 30, 2011, we recognized $14.4 million in acquisition expenses, $3.9 million related to the integration of new acquisitions, $1.1 million of restructuring costs, $0.5 million in litigation settlement, and $0.3 million loss related to the Mexico divestiture, partially offset by $2.1 million related to a change in fair value of contingent consideration.

Net Interest Expense: Net interest expense increased to $38.3 million in the nine months ended September 30, 2012 from $35.9 million during the same period in 2011 due to increased borrowings. Our interest expense was higher in 2012 due to a higher rate on our revolver borrowings and higher debt levels, partially offset by an additional interest expense of $1.2 million in the second quarter of 2011 due to the acceleration of amortization of finance fees related to our term loan that was repaid prior to scheduled maturity of June 2012.

Income Tax Expense: Income tax expense increased to $110.3 million for the nine months ended September 30, 2012 from $99.1 million for the comparable period in 2011. The increase was due to higher taxable income. The tax rates for the nine months ended September 30, 2012 and 2011 were 35.6% and 36.5%, respectively.

LIQUIDITY AND CAPITAL RESOURCES

Our $1.0 billion senior credit facility maturing in September 2016, our $100.0 million private placement notes maturing April 2015, our $175.0 million private placement notes maturing in October 2017, and our $225.0 million private placement notes maturing in October 2020, all require us to comply with various financial, reporting

25

and other covenants and restrictions, including a restriction on dividend payments. The financial debt covenants are the same for the senior credit facility and the private placement notes. At September 30, 2012, we were in compliance with all of our financial debt covenants.

As of September 30, 2012, we had $231.8 million of borrowings outstanding under our $1.0 billion senior unsecured credit facility, which includes foreign currency borrowings of $81.3 million. We also had $158.4 million committed to outstanding letters of credit under this facility. The unused portion of the revolving credit facility as of September 30, 2012 was $609.8 million. At September 30, 2012, our interest rates on borrowings under our revolving credit facility, including our facility fee, were as follows:

• For short-term borrowing (overnight): Federal funds rate plus 0.75%, the Eurocurrency rate plus 1.25% or prime rate plus 0.375%, whichever is higher; and

• For borrowings greater than one month: LIBOR plus 1.375%.

The weighted average rate of interest on the unsecured revolving credit facility was 1.71% per annum at September 30, 2012.

As of September 30, 2012, we had outstanding $100.0 million of seven-year 5.64% unsecured senior notes issued to nine institutional purchasers in a private placement completed in April 2008. Interest is payable in arrears semi-annually on April 15 and October 15 beginning on October 15, 2009, and principal is payable at the maturity of the notes on April 15, 2015.

As of September 30, 2012, we had outstanding $175.0 million of seven-year 3.89% unsecured senior notes and $225.0 million of 10-year 4.47% unsecured senior notes issued to 39 institutional purchasers in a private placement completed in October 2010. Interest is payable in arrears on April 15 and October 15 beginning on April 15 2011, and principal is payable at the maturity of the notes, October 15, 2017 in the case of the seven-year notes and October 15, 2020 in the case of the 10-year notes.

As of September 30, 2012, we had $365.3 million in other debt outstanding, which includes promissory notes issued in connection with acquisitions during 2004 through 2012, other foreign subsidiary bank debt, and capital lease obligations.

As of September 30, 2012, we had a $200.0 million term loan, with a rate of 1.09%, due in December 2012. We used the proceeds from this short term loan to pay down long term debt under our senior credit facility.

Working Capital: At September 30, 2012, our working capital decreased $167.6 million to negative $103.9 million compared to $63.7 million at December 31, 2011. The negative working capital is due to a short term loan of $200.0 million, proceeds of which were used to pay down long term debt. Working capital, excluding the $200.0 million short term loan, increased by $32.4 million with increases in current assets of $26.8 million and decreases in current liabilities of $5.6 million.

26

Current assets increased primarily due to an increase in accounts receivable of $23.7 million. During the nine months ended September 30, 2012 we acquired $18.7 million in accounts receivable, of which $6.3 million was acquired in the third quarter, compared to only $0.2 million was acquired in the fourth quarter of 2011. Days sales outstanding (“DSO”) was calculated at 59 days at December 31, 2011 and 60 days at September 30, 2012 which was affected by both acquired receivables and the number of collection days in September 2012.

Current liabilities, excluding the $200.0 million short term loan, decreased by $5.6 million. Accounts payable increased by $13.6 million, of which $2.1 million can be attributed to acquisitions in the third quarter of 2012 and the remainder related primarily to timing of payments. Accrued liabilities decreased by $18.5 million primarily related to a reduction in our taxes payable. Other current liabilities increased by $10.8 million primarily related to an increase in acquisition payments due.

Net Cash Provided or Used: Net cash provided by operating activities increased $62.0 million, or 28.8%, to $277.1 million during the nine months ended September 30, 2012 compared to $215.2 million for the comparable period in 2011. This increase was driven by strong collections and higher revenues both domestically and internationally. Our days sales outstanding (“DSO”) was at 60 days in 2012 and 58 days for the comparable period 2011, while our DSO at December 31, 2011 was at 59 days. This increase was primarily due to acquisitions completed in 2011. Cash provided by operations as a ratio to net income is 139% and 125% for the nine months ended September 30, 2012 and 2011, respectively.

Net cash used in investing activities for the nine months ended September 30, 2012 was $204.3 million compared to $486.1 million in the comparable period in 2011. We had $314.0 million decrease in cash spent to acquire new businesses; during April of 2011 we acquired Healthcare Waste Solutions, Inc. for $237.0 million in cash. Our capital expenditures increased $14.7 million and, as a percentage of revenue, it increased to 3.7% in 2012 from 3.0% for the comparable period 2011.

Net cash used in financing activities was $80.7 million during the nine months ended September 30, 2012 compared to $212.0 million net cash provided in the comparable period in 2011. A change of $366.4 million related to increase in net repayments of our senior credit facility, and partially offset by share repurchases of $2.9 million compared to $81.2 million in 2011, a decrease of $78.3 million.

Guarantees: We have guaranteed a loan to JPMorganChase Bank N.A. on behalf of Shiraishi-Sogyo Co. Ltd (“Shiraishi”). Shiraishi is a customer in Japan that is expanding its medical waste management business and has a one year loan with a current balance of $6.3 million with JPMorganChase Bank N.A. that matures on May 31, 2013. We also have extended loans to Shiraishi for $15.4 million in support of its medical waste business. These amounts are collateralized with the assets of Shiraishi and related companies.

Annual Impairment Test: We completed our annual goodwill impairment test during the second quarter of 2012. We chose to perform a quantitative assessment using

27

both a market approach and an income approach to determine the fair value of our reporting units. The market approach compares the market capitalization of the Company as a whole, which is the fair value, and allocates a portion of that fair value to each reporting unit based on that reporting unit’s historic cash flows, as measured by a modified Earnings Before Interest, Taxes, Depreciation, and Amortization. The income approach uses estimates of future cash flows discounted to a present value to arrive at a fair value. Both the market and income approaches indicated no impairment to any of our three reporting units.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are subject to market risks arising from changes in interest rates. Our potential additional interest expense over one year that would result from a hypothetical, instantaneous and unfavorable change of 100 basis points in the interest rate on all of our variable rate obligations would be approximately $5.6 million on a pre-tax basis.

We have exposure to foreign currency fluctuations. We have subsidiaries in eleven foreign countries whose functional currency is the local currency. Changes in foreign currency exchange rates could unfavorably impact our consolidated results of operations.

We have exposure to commodity pricing for gas and diesel fuel for our trucks and for the purchase of containers and boxes. We do not hedge these items to manage the exposure.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our management, with the participation of our Chairman and Chief Executive Officer and our Chief Financial Officer, conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the fiscal quarter covered by this Report. On the basis of this evaluation, our Chairman and Chief Executive Officer and our Chief Financial Officer each concluded that our disclosure controls and procedures were effective.

The term “disclosure controls and procedures” is defined in Rule 13a-15(e) of the Securities Exchange Act of 1934 as “controls and other procedures designed to ensure that information required to be disclosed by the issuer in the reports, files or submits under the Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms.” Our disclosure controls and procedures are designed to ensure that material information relating to us and our consolidated subsidiaries is accumulated and communicated to our management, including our Chairman and Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding our required disclosures.

28

Internal Control Over Financial Reporting

The term internal control over financial reporting is defined as a process designed by, or under the supervision of, the issuers’ principal executive and principal financial officers, and effected by the issuer’s Board of Directors, management, and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. During the quarter ended September 30, 2012, there were no changes in our internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

FROM TIME TO TIME WE ISSUE FORWARD-LOOKING STATEMENTS RELATING TO SUCH THINGS AS ANTICIPATED FINANCIAL PERFORMANCE, BUSINESS PROSPECTS, ACQUISITION ACTIVITIES AND SIMILAR MATTERS.

THESE FORWARD-LOOKING STATEMENTS MAY INVOLVE RISKS AND UNCERTAINTIES, SOME OF WHICH ARE BEYOND OUR CONTROL (FOR EXAMPLE, GENERAL ECONOMIC CONDITIONS). OUR ACTUAL RESULTS COULD DIFFER SIGNIFICANTLY FROM THE RESULTS DESCRIBED IN THE FORWARD-LOOKING STATEMENTS. FACTORS THAT COULD CAUSE SUCH DIFFERENCES INCLUDE DIFFICULTIES IN COMPLETING THE INTEGRATION OF ACQUIRED BUSINESSES, CHANGES IN GOVERNMENTAL REGULATION OF MEDICAL WASTE COLLECTION AND TREATMENT, AND INCREASES IN TRANSPORTATION AND OTHER OPERATING COSTS, AS WELL AS VARIOUS OTHER FACTORS.

For financial reporting purposes, our 2012 and 2011 acquisitions were accounted for using the acquisition method of accounting. These acquisitions resulted in recognition of goodwill in our financial statements reflecting the premium paid to acquire businesses that we believe are complementary to our existing operations and fit our strategy. During the nine months ended September 30, 2012, we recognized a net increase in goodwill of $87.4 million excluding the effect of foreign currency translation (see Note 10 – Goodwill and Other Intangible Assets, in the Notes to the Condensed Consolidated Financial Statements). A net of $55.8 million was assigned to our United States reporting segment, and $31.6 million was assigned to our International reporting segment. Approximately $56.7 million of the goodwill recognized during the nine months ended September 30, 2012 will be deductible for income taxes.

During the nine months ended September 30, 2012, we recognized a net increase in intangible assets of $98.7 million excluding the effect of foreign currency translation. The changes include $72.5 million in the estimated fair value of acquired customer relationships with amortizable lives of 15-40 years, $23.4 million in permits with indefinite lives, $2.7 million in a tradename with an amortizable life of 15 years, and $0.1 million in other intangible asset with amortizable life of 10 years.

The purchase prices for these acquisitions in excess of acquired tangible assets have been primarily allocated to goodwill and other intangibles and are preliminary pending completion of certain intangible asset valuations and completion accounts. The following table summarizes the preliminary purchase price allocation for current period acquisitions and other adjustments to purchase price allocations during the nine months ended September 30, 2012:

Fixed assets	$	21,572

Noncontrolling interests		15,611
Total purchase price allocation	$	215,652

During the nine months ended September 30, 2012 and 2011, the Company incurred $6.2 million and $14.4 million, respectively, of acquisition related expenses. These expenses are included with SG&A on our Condensed Consolidated Statements of Income and Comprehensive Income.

In July 2012, we were required by the United Kingdom Competition Committee to divest a business acquired in 2011. The sale price of the business was $0.7 million and resulted in a pretax loss of $4.9 million which is included in “Selling, general and administrative expenses” (“SG&A”).

BASIS OF PRESENTATION

NOTE 1 – BASIS OF PRESENTATION

The accompanying condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. However, the Company believes the disclosures included in the accompanying condensed consolidated financial statements are adequate to make the information presented not misleading. In our opinion, all adjustments necessary for a fair presentation for the periods presented have been reflected and are of a normal recurring nature. These condensed consolidated financial statements should be read in conjunction with the Stericycle, Inc. and Subsidiaries Consolidated Financial Statements and notes thereto for the year ended December 31, 2011, as filed with our Annual Report on Form 10-K for the year ended December 31, 2011. The results of operations for the nine months ended September 30, 2012 are not necessarily indicative of the results that may be achieved for the entire year ending December 31, 2012.

There were no material changes in the Company’s critical accounting policies since the filing of its 2011 Form 10-K. As discussed in the 2011 Form 10-K, the preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make certain estimates and assumptions that affect the amount of reported assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and revenues and expenses during the periods reported. Actual results may differ from those estimates.

Certain amounts in previously issued financial statements have been reclassified to conform to the current period presentation.

GOODWILL AND OTHER INTANGIBLE ASSETS

GOODWILL AND OTHER INTANGIBLE ASSETS

NOTE 10 – GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill and identifiable indefinite lived intangible assets are not amortized, but are subject to an annual impairment test. Other intangible assets are amortized over their useful lives. We have determined that our customer relationships have useful lives from 14 to 40 years based upon the type of customer, with a weighted average remaining useful life of 30.0 years. We have covenants not-to-compete intangibles with useful lives from 4 to 14 years, with a weighted average remaining useful life of 4.8 years. We have tradename intangibles with useful lives from 15 to 40 years, with a weighted average remaining useful life of 16.8 years. We have determined that our permits have indefinite lives due to our ability to renew these permits with minimal additional cost, and therefore they are not amortized.

We have two geographical reporting segments, “United States” and “International”, both of which have goodwill. The changes in the carrying amount of goodwill since December 31, 2010, by reportable segment, were as follows:

In thousands
	United States			International			Total
Balance as of December 31, 2010	$	1,279,758		$	316,006		$	1,595,764

Balance as of December 31, 2011	$	1,506,416		$	407,287		$	1,913,703

Balance as of September 30, 2012	$	1,562,199		$	443,499		$	2,005,698

Current year adjustments to goodwill for 2011 acquisitions are primarily due to the finalization of intangible asset valuations.

As of September 30, 2012 and December 31, 2011, the values of the intangible assets were as follows:

In thousands
	September 30, 2012						December 31, 2011
	Gross Carrying Amount		Accumulated Amortization		Net Value		Gross Carrying Amount		Accumulated Amortization		Net Value

Total	$	681,273	$	57,855	$	623,418	$	588,668	$	42,050	$	546,618

During the quarters ended September 30, 2012 and 2011, the aggregate amortization expense was $5.6 million and $4.2 million, respectively. For the nine months ended September 30, 2012 and 2011, the aggregate amortization expense was $15.7 million and $11.1 million, respectively.

The estimated amortization expense for each of the next five years, assuming no additional amortizable intangible assets, is as follows for the years ended December 31:

In thousands
2012	$	21,213
2013		22,924
2014		22,767
2015		22,444
2016		22,307

Future amortization expense may fluctuate depending on changes in foreign currency rates, future acquisitions, or changes to the estimated amortizable life of the intangibles. The estimates for amortization expense noted above are based upon foreign exchange rates as of September 30, 2012.

During the quarter ended June 30, 2012, we performed our annual goodwill impairment evaluation for our three reporting units, Domestic Regulated Waste, Domestic Regulated Returns and Recall Management Services, and International. We calculated fair value for our reporting units using two methods, one a market approach and the other an income approach. Both the market and income approaches indicated no impairment to goodwill to any of our three reporting units.

Market Approach: Our market approach begins by calculating the market capitalization of the Company using the average stock price for the prior 30 days and the outstanding share count at June 30, 2012. We then look at the Company’s Earnings Before Interest, Tax, Depreciation, and Amortization (“EBITDA”), adjusted for stock compensation expense and other items, such as change in fair value of contingent consideration, restructuring costs and plant closure expenses, for the prior twelve months. The calculated market capitalization is divided by the modified EBITDA to arrive at a valuation multiple. The fair value of each reporting unit is then calculated by taking the product of the valuation multiple and the trailing twelve month modified EBITDA of that reporting unit. The fair value was then compared to the reporting units’ book value and determined to be in excess of the book value. We believe that starting with the fair value of the company as a whole is a reasonable measure as that fair value is then allocated to each reporting unit based on that reporting unit’s individual earnings. A sustained drop in our stock price would have a negative impact to our fair value calculations. A temporary drop in earnings of a reporting unit would have a negative impact to our fair value calculations.

The results of our goodwill impairment test using the market approach indicated the fair value of our reporting units exceeded book value by a substantial amount, in excess of 100% of book value.

Income Approach: The income approach uses expected future cash flows of each reporting unit and discounts those cash flows to present values. Expected future cash flows are calculated using management assumptions of internal growth, capital expenditures, and cost efficiencies. Future acquisitions are not included in the expected future cash flows. We use a discount rate based on our Company calculated weighted average cost of capital which is adjusted for each of our reporting units based on size risk premium and country risk premium. Significant assumptions used in the income approach include realization of future cash flows and the discount rate used to present value those cash flows.

The results of our goodwill impairment test using the income approach indicated the fair value of our reporting units exceeded book value by a substantial amount; in excess of 100%.

We perform our annual impairment analysis of our indefinite lived intangibles (facility permits) during the quarter ended December 31 of each year.

INCOME TAXES

NOTE 5 – INCOME TAXES

We and our subsidiaries file U.S. federal income tax returns and income tax returns in various states and foreign jurisdictions.

The Company has recorded accruals to cover uncertain tax positions taken on previously filed tax returns. Such liabilities relate to additional taxes, interest and penalties the Company may be required to pay in various tax jurisdictions. During the course of examinations by various taxing authorities, proposed adjustments may be asserted. The Company evaluates such items on a case-by-case basis and adjusts the accrual for uncertain tax positions. During the quarter ended September 30, 2012 we had immaterial net decreases to our accruals related to a reassessment of previous and current uncertain tax positions.

FAIR VALUE MEASUREMENTS

NOTE 4 – FAIR VALUE MEASUREMENTS

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

Level 1 – Quoted prices in active markets for identical assets or liabilities.

Level 2 – Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.

We recorded a $0.5 million asset related to the fair value of a treasury lock hedge. The treasury lock hedge locked in the interest rate on the issuance of expected private placement debt and was used to eliminate interest rate risk. The fair value of the hedge was calculated by taking the present value of the difference between the locked rate and treasury rates at September 30, 2012. The hedge will terminate in October 2012 at which time the settlement amount, net of tax, will be recognized in accumulated other comprehensive income and amortized to net interest expense over the life of the underlying debt.

We had contingent consideration liabilities recorded in the amounts of $22.9 million, of which $14.0 million is current, at September 30, 2012, and $9.9 million at December 31, 2011 using Level 3 inputs. Contingent consideration represents amounts to be paid as part of acquisition consideration only if certain future events occur. These events are usually acquisition targets for revenues or earnings. We arrive at the fair value of contingent consideration by applying a weighted probability of potential outcomes to the maximum possible payout. The calculation of these potential outcomes is dependent on both past financial performance and management assumptions about future performance. If the financial performance measures were all fully met, our maximum liability would be $24.9 million. Contingent consideration liabilities are reassessed each quarter and are reflected in the condensed consolidated balance sheets as part of “Other current liabilities” or “Other liabilities”. Changes to contingent consideration are reflected in the table below:

In thousands
Contingent consideration at December 31, 2011	$	9,921

Changes in fair value reflected in Selling, general, and administrative expenses		591
Contingent consideration at September 30, 2012	$	22,861

Fair Value of Debt: At September 30, 2012, the fair value of the Company’s debt obligations was estimated, using Level 2 inputs, at $1.34 billion compared to a carrying amount of $1.30 billion. At December 31, 2011, the fair value of the Company’s debt obligations was estimated, using Level 2 inputs, at $1.41 billion compared to a carrying amount of $1.38 billion. The fair values were estimated using market interest rates for comparable instruments. The Company has no current plans to retire a significant amount of its debt prior to maturity.

There were no movements of items between fair value hierarchies.

The Black-Scholes option-pricing model is used in determining the fair value of each option grant. The expected term of options granted is based on historical experience. Expected volatility is based upon historical volatility. The expected dividend yield is zero. The risk-free interest rate is based upon the U.S. Treasury yield rates for a comparable period. The assumptions that we used in the Black-Scholes model are as follows:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2012			2011			2012			2011

NEW ACCOUNTING STANDARDS

NOTE 3 – NEW ACCOUNTING STANDARDS

Accounting Standards Recently Adopted

Other Comprehensive Income

On January 1, 2012, Stericycle adopted changes issued by the Financial Accounting Standards Board (“FASB”) to guidance on the presentation of comprehensive income. These changes give an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements; the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity was eliminated. The items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income were not changed. Additionally, no changes were made to the calculation and presentation of earnings per share. Part of the adopted standard related to presentation of reclassification of items out of accumulated other comprehensive income have been deferred. Other than the change in presentation, these changes did not have an impact on our financial statements.

Goodwill Impairment Testing

On January 1, 2012, Stericycle adopted changes issued by the FASB to guidance on the testing for impairment of goodwill. Previous guidance required an entity to test goodwill for impairment, on at least an annual basis, by comparing the fair value of a reporting unit with its carrying amount, including goodwill (step one). If the fair value of a reporting unit is less than its carrying amount, then the second step of the test must be performed to measure the amount of the impairment loss, if any. Under the amendments, an entity has the option to use a qualitative assessment, that it is more likely than not (greater than 50%) that the fair value of goodwill is less than its carrying amount. We performed our annual test for goodwill impairment during the second quarter and chose to perform a quantitative assessment.

Fair Value Measurement

On January 1, 2012, Stericycle adopted changes issued by the FASB for additional disclosures concerning the valuation processes used and sensitivity of the fair value measurement to changes in unobservable inputs for those items categorized as Level 3, a reporting entity’s use of a nonfinancial asset in a way that differs from the asset’s highest and best use, and the categorization by level in the fair value hierarchy for items required to be measured at fair value for disclosure purposes only. Other than the change in presentation, these changes did not have an impact on our financial statements.

Accounting Standards Issued But Not Yet Adopted

Testing Indefinite-Lived Intangible Assets for Impairment

On July 27, 2012 the FASB issued guidance allowing a company to perform a qualitative assessment in determining whether an indefinite lived intangible asset is impaired. This new guidance is similar to the previously issued guidance allowing a qualitative assessment when performing annual goodwill impairment testing. The guidance also changes when a company should perform an interim period test for impairment, allowing for positive evidence to offset negative evidence when determining whether an interim impairment test is required. The new guidance should not affect the ultimate outcome of an impairment test; therefore there will be no impact on our financial statements. The effective date of this guidance for our Company is January 1, 2013; however, the guidance allows for early adoption. We are currently evaluating whether we will early adopt this guidance. We perform our annual test for impairment for indefinite lived intangibles in the fourth quarter.
