Sotera Health Company

Notes to Consolidated Financial Statements

1.Basis of Presentation

Principles of Consolidation – Sotera Health Company (also referred to herein as the “Company,” “we,” “our,” “us” or “its”), is a leading global provider of mission-critical end-to-end sterilization solutions, lab testing and advisory services for the healthcare industry with operations primarily in the Americas, Europe and Asia.

We operate and report in three segments, Sterigenics, Nordion and Nelson Labs. We describe our reportable segments in Note 18, “Segment Information”. All significant intercompany balances and transactions have been eliminated in consolidation.

Noncontrolling interests represent the noncontrolling stockholders’ proportionate share of the total equity in the Company’s consolidated subsidiaries. We consolidate the results of operations of these subsidiaries with our results of operations. In the second quarter of 2021, we purchased the outstanding noncontrolling interests of 15% and 33% of our two China subsidiaries. Refer to Note 4, “Acquisitions” for additional details. We reflect the noncontrolling interests in our two China subsidiaries for all periods presented prior to this purchase transaction on our Consolidated Statements of Operations and Comprehensive Income (Loss) as “Net income attributable to noncontrolling interests.”

On March 11, 2021, we purchased the 15% noncontrolling interest that remained from the August 2018 acquisition of Nelson Laboratories Fairfield, Inc. (“Nelson Labs Fairfield”). As the purchase of this noncontrolling interest was mandatorily redeemable, no earnings were allocated to this noncontrolling interest. See Note 4, “Acquisitions” for additional details.

In July 2020, we acquired a 60% equity ownership interest in a joint venture to construct an E-beam facility in Alberta, Canada in connection with our acquisition of Iotron Industries Canada, Inc. (“Iotron”). Refer to Note 4, “Acquisitions” for additional information. We have determined this to be an investment in a variable interest entity (“VIE”). The investment is not consolidated as the Company has concluded that we are not the primary beneficiary of the VIE. The Company accounts for the joint venture using the equity method. The investment is reflected within “Investment in unconsolidated affiliates” on the Consolidated Balance Sheets.

Use of Estimates – In preparing our consolidated financial statements in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”), we make estimates and assumptions that affect the amounts reported and the accompanying notes. We regularly evaluate the estimates and assumptions used and revise them as new information becomes available. Actual results may vary from those estimates.

Interim Financial Statements – The accompanying consolidated financial statements include the assets, liabilities, operating results, and cash flows of the Company and its wholly owned subsidiaries. These financial statements are prepared in accordance with U.S. GAAP for interim financial information and the instructions to the Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. These unaudited interim financial statements should be read in conjunction with the Company's annual consolidated financial statements and accompanying notes on Form 10-K for the year ended December 31, 2020.

2.Recent Accounting Standards

ASUs Issued But Not Yet Adopted

Under the Jumpstart Our Business Startups Act of 2012, emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies. As an emerging growth company, we have elected to take advantage of the extended transition period for complying with new or revised accounting standards until those standards would otherwise apply to private companies or at which time we conclude it is appropriate to avail ourselves of early adoption provisions of applicable standards. As a result, our results of operations and financial statements may not be comparable to the results of operations and financial statements of other companies who have adopted the new or revised accounting standards.

Notes to Consolidated Financial Statements

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (“ASU 2016-13”): Measurement of Credit Losses on Financial Instruments, and subsequently issued additional guidance that modified ASU 2016-13. The standard requires an entity to change its accounting approach in determining impairment of certain financial instruments, including trade receivables, from an “incurred loss” to a “current expected credit loss” model. We intend to adopt the standard as of January 1, 2022. We are currently assessing the effect that ASU 2016-13 will have on our financial position, results of operations, and disclosures.

In December 2019, the FASB issued ASU 2019-12 - Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The standard simplifies the accounting for income taxes and makes a number of changes meant to add or clarify guidance on accounting for income taxes. This update is effective for annual financial statement periods beginning after December 15, 2021 and interim periods within fiscal years beginning after December 15, 2022, with early adoption permitted in any interim period for which financial statements have not yet been filed. We are currently assessing the effect that ASU 2019-12 will have on our financial position, results of operations, and disclosures.

Notes to Consolidated Financial Statements

When we receive consideration from a customer prior to transferring goods or services under the terms of a sales contract, we record deferred revenue, which represents a contract liability. Deferred revenue totaled $4.9 million and $6.1 million at September 30, 2021 and December 31, 2020, respectively. We recognize deferred revenue after all revenue recognition criteria are met.

4.Acquisitions

Acquisition of Noncontrolling Interests in China Subsidiaries

On May 18, 2021, the Company acquired the remaining 15% and 33% noncontrolling interests associated with our two subsidiaries located in China. As a result, both entities are now 100% owned by the Company. The purchase price of the remaining equity interests was approximately $8.6 million, net of the cancellation of an $0.8 million demand note. The Company paid 90% of the cash consideration on the acquisition date. The remaining amounts were partially settled in post-closing payments in the third quarter of 2021; $0.2 million of the post-closing payment remains outstanding as of September 30, 2021 subject to the terms of the equity transfer agreements. As a result of the transactions, we continue to consolidate both of these subsidiaries, however, as of May 18, 2021, we no longer record noncontrolling interests in the consolidated financial statements as these subsidiaries are fully owned by the Company. The purchases were accounted for as equity transactions. As a result of these transactions, noncontrolling interests were reduced by $2.8 million reflecting the carrying value of the interest with $5.8 million of the difference charged to additional paid-in capital.

Acquisition of BioScience Laboratories, LLC

On March 8, 2021, we acquired BioScience Laboratories, LLC (“BioScience Labs”) for approximately $13.5 million, net of $0.2 million of cash acquired plus the contemporaneous repayment of BioScience Labs’ outstanding debt of $1.9 million. BioScience is a provider of outsourced topical antimicrobial product testing in the pharmaceutical, medical device, and consumer products industries with one location in Bozeman, Montana.

The purchase price of BioScience Labs was allocated to the underlying assets acquired and liabilities assumed based upon management's estimated fair values at the date of acquisition. Changes to the allocation of the purchase price may occur as these measurements are completed. Approximately $10.6 million of goodwill was recorded related to the BioScience Labs acquisition, representing the excess of the purchase price over the preliminary estimated fair values of all the assets acquired and liabilities assumed. The Company funded this acquisition using available cash. The acquisition price and the results of operations for this acquired entity are not material in relation to the Company's consolidated financial statements.

Acquisition of Mandatorily Redeemable Noncontrolling Interest - Nelson Labs Fairfield

On March 11, 2021, we completed the acquisition of the remaining 15% ownership of Nelson Labs Fairfield for $12.4 million, resulting in a gain of $1.2 million included in “Other expense (income), net” in the Consolidated Statements of Operations and Comprehensive Income (Loss) relative to the $13.6 million previously accrued. Pursuant to the terms of the August 2018 acquisition, we initially acquired 85% of the equity interests of Nelson Labs Fairfield in August 2018 and were obligated to acquire the remaining 15% noncontrolling interest within three years from the date of the acquisition.

Acquisition of Iotron Industries Canada, Inc.

On July 31, 2020, we acquired Iotron for approximately $105.2 million. Iotron was an independent contact sterilizer with two North American locations in Vancouver, Canada, and Columbia City, Indiana. Each location uses proprietary high energy electron beam technology to process products for orthopedic, medical device, plastics, and agricultural businesses. The acquisition was financed by the issuance of $100.0 million of First Lien Notes due 2026. Refer to Note 9, “Long-Term Debt” for additional details.

As part of this acquisition, we also acquired Iotron’s 60% equity ownership interest in a joint venture to construct an E-beam facility in Alberta, Canada. The joint venture is accounted for using the equity method.

Notes to Consolidated Financial Statements

The estimated fair value of the underlying acquired assets and assumed liabilities of the Iotron acquisition and the measurement period adjustments recognized during the nine months ended September 30, 2021, were as follows:


(thousands of U.S. dollars)
Allocation of purchase price to the fair value of net assets acquired (net of cash acquired):	Amount recognized as of December 31, 2020		Measurement Period Adjustments		Amount recognized as of September 30, 2021
Goodwill	$	69,046	$	(19,447)	$	49,599
Intangibles	16,427		26,273		42,700

Other assets/liabilities, net	(5,846)		(6,993)		(12,839)
Total purchase price	$	105,187	$	—	$	105,187

Approximately $49.6 million of goodwill was recorded related to the Iotron acquisition, representing the excess of the purchase price over the estimated fair values of all the assets acquired and liabilities assumed. The fair value allocated to goodwill and tangible and intangible assets are deductible for tax purposes. The qualitative elements of goodwill primarily represent the expanded future growth opportunities for the combined company and the addition of Iotron’s highly skilled workforce. The Company recorded $39.1 million and $3.6 million for intangible assets as part of the acquisition related to customer relationships and employee non-compete agreements, respectively. The estimated useful lives of the identifiable finite-lived intangible assets range from 5 to 15 years.

Iotron’s results of operations are included in our consolidated financial statements from the date of the transaction within the Sterigenics segment. The unaudited pro forma consolidated results for the three and nine months ended September 30, 2020, are reflected in the pro forma table below had the transaction occurred on January 1, 2020. The following unaudited supplemental pro forma financial information is based on our historical consolidated financial statements and Iotron’s historical consolidated financial statements, as adjusted for amortization of acquired intangible assets, an increase in interest expense resulting from interest on the First Lien Notes to finance the acquisition, and to reflect the change in the estimated income tax rate for federal and state purposes.

(a)Includes certain transportation certifications, a class 1B nuclear license and other intangibles related to obtaining such licensure. These assets are considered indefinite-lived as the decision for renewal by the Canadian Nuclear Safety Commission is highly based on a licensee’s previous assessments, reported incidents, and annual compliance and inspection results. New applications for license can take a significant amount of time and cost; whereas an existing licensee with a historical record of compliance and current operating conditions more than likely ensures renewal for another 10 years license period as Nordion has demonstrated over its 75 years of history.

Amounts include the impact of foreign currency translation. Fully amortized amounts are written off.

Amortization expense for other intangible assets was $21.2 million ($5.3 million is included in “Cost of revenues” and $15.9 million in “Selling, general and administrative expenses”) and $65.3 million ($17.2 million is included in “Cost of revenues” and $48.1 million in “Selling, general and administrative expenses”) in the Consolidated Statements of Operations and Comprehensive Income (Loss) for the three and nine months ended September 30, 2021, respectively.

Debt Facilities

Senior Secured Credit Facilities

On December 13, 2019, Sotera Health Holdings, LLC (“SHH”), our wholly owned subsidiary, entered into senior secured first lien credit facilities (the “Senior Secured Credit Facilities”), consisting of both a prepayable senior secured first lien term loan (the “Term Loan”) and a senior secured first lien revolving credit facility (the “Revolving Credit Facility”) pursuant to a first lien credit agreement (the “Credit Agreement”). The Term Loan matures on December 13, 2026, and the Revolving Credit Facility's original maturity date was December 13, 2024. On December 17, 2020, we increased the capacity of our Revolving Credit Facility from $190.0 million to $347.5 million. The Senior Secured Credit Facilities also provide SHH the right at any time and under certain conditions to request incremental term loans or incremental revolving credit commitments based on a formula defined in the Senior Secured Credit Facilities. As of September 30, 2021 and December 31, 2020, total borrowings under the Term Loan were $1,763.1 million in each period, respectively, and there were no borrowings outstanding on the Revolving Credit Facility. The weighted average interest rate on borrowings under the Term Loan for the three months ended September 30, 2021 and September 30, 2020 was 3.25% and 5.50%, respectively, and 3.51% and 5.73% for the nine months ended September 30, 2021 and September 30, 2020, respectively.

On January 20, 2021, we closed on an amendment repricing our Term Loan. The interest rate spread over the London Interbank Offered Rate (“LIBOR”) on the facility was reduced from 450 basis points to 275 basis points, and the facility’s LIBOR floor was reduced from 100 basis points to 50 basis points. The changes result in an effective reduction in current interest rates of 2.25%. In connection with this amendment, we wrote off $11.3 million of unamortized debt issuance and discount costs and incurred an additional $2.9 million of expense related to debt issuance costs attributable to the refinancing. These costs were recorded to “Loss on extinguishment of debt” in our Consolidated Statements of Operations and Comprehensive Income (Loss).

As of September 30, 2021 and December 31, 2020, capitalized debt issuance costs totaled $2.8 million and $3.4 million, respectively, and debt discounts totaled $18.2 million and $31.6 million, respectively, related to the Senior Secured Credit Facilities. Such costs are recorded as a reduction of debt on our Consolidated Balance Sheets and amortized as a component of interest expense over the term of the debt agreement.

On March 26, 2021, we amended the Revolving Credit Facility, to (i) decrease the Applicable Rate (as defined in the Credit Agreement) related to any Revolving Loans (as defined in the Credit Agreement) from a rate per annum that ranged from an alternative base rate (“ABR”) plus 2.50% to ABR plus 3.00% depending on SHH’s Senior Secured First Lien Net Leverage Ratio to ABR plus 1.75%; and in the case of Eurodollar Loans (as defined in the Credit Agreement) from a rate per annum which ranged from the Adjusted LIBOR plus 3.50% to the Adjusted LIBOR plus 4.00% depending on SHH’s Senior Secured First Lien Net Leverage Ratio (as defined in the Credit Agreement), to the Adjusted LIBOR (as defined in the Credit Agreement) plus 2.75%, and (ii) extend the maturity date of the Revolving Facility from December 13, 2024 to June 13, 2026. The other material terms of the Credit Agreement are unchanged and the amendment does not change the capacity of our Revolving Credit Facility, which is $347.5 million. No unamortized debt issuance costs associated with the Revolving Credit Facility were written off and direct fees and costs incurred in connection with the amendment were immaterial.

Table of Contents

Sotera Health Company

Notes to Consolidated Financial Statements

As of September 30, 2021 and December 31, 2020, there were no borrowings on the Revolving Credit Facility. SHH borrowed $50.0 million on the Revolving Credit Facility during the first quarter of 2020 which was repaid in the second quarter of 2020. The interest rate on the borrowings under the Revolving Credit Facility during 2020 averaged approximately 5.0%.

All of SHH’s obligations under the Senior Secured Credit Facilities are unconditionally guaranteed by the Company and each existing and subsequently acquired or organized direct or indirect wholly-owned domestic restricted subsidiary of the Company, with customary exceptions including, among other things, where providing such guarantees is not permitted by law, regulation or contract or would result in material adverse tax consequences. All obligations under the Senior Secured Credit Facilities, and the guarantees of such obligations, are secured by substantially all assets of the borrower and guarantors, subject to permitted liens and other exceptions and exclusions, as outlined in the Senior Secured Credit Facilities.

Outstanding letters of credit are collateralized by encumbrances against the Revolving Credit Facility and the collateral pledged thereunder, or by cash placed on deposit with the issuing bank. As of September 30, 2021, the Company had $67.6 million of letters of credit issued against the Revolving Credit Facility, resulting in total availability under the Revolving Credit Facility of $279.9 million.

First Lien Notes

On July 31, 2020, SHH issued $100.0 million aggregate principal amount of senior secured first lien notes due 2026 (the “First Lien Notes”), which were scheduled to mature on December 13, 2026. On August 27, 2021 SHH redeemed in full the $100.0 million aggregate principal amount of the First Lien Notes. In connection with this redemption, the Company paid a $3.0 million early redemption premium, in accordance with the terms of the First Lien Notes Indenture, and wrote off $3.4 million of debt issuance and discount costs. The Company recognized these expenses within “Loss on extinguishment of debt” in our Consolidated Statements of Operations and Comprehensive Income (Loss) for the three and nine months ended September 30, 2021.

Prior to the redemption, the First Lien Notes bore interest at a rate equal to LIBOR subject to a 1.00% floor plus 6.00% per annum. Interest was payable on a quarterly basis with no principal due until maturity. The weighted average interest rate on the First Lien Notes during 2021 up to the August 27, 2021 redemption date was 7.00%.

2020 Debt Repayments

On November 24, 2020, we closed our initial public offering (the “IPO”), in which we sold 53,590,000 shares of our common stock at a price of $23.00 per share, which included the full exercise by the underwriters of their option to purchase up to an additional 6,990,000 shares of common stock. We raised approximately $1.2 billion in net proceeds after deducting underwriters’ discounts and commissions. We used the net proceeds received by us from the IPO to (i) redeem $770.0 million in aggregate principal amount of the Second Lien Senior Secured Notes with an original maturity date of December 13, 2027 (the “Second Lien Notes”), plus accrued and unpaid interest thereon and $15.4 million of redemption premium, (ii) repurchase 1,568,445 shares of our common stock from certain of our executive officers at a purchase price per share equal to the IPO price per share of our common stock less an amount equal to the underwriting discounts and commissions payable thereon and (iii) repay $341.0 million of the outstanding indebtedness under the Term Loan, plus accrued and unpaid interest thereon. In connection with the debt repayments, we wrote off $28.9 million of debt issuance and discount costs and recognized $15.4 million in premiums paid for the early extinguishment of the Second Lien Notes. We recognized these costs within “Loss on extinguishment of debt” in our Consolidated Statements of Operations and Comprehensive Income (Loss) in the fourth quarter of 2020.

Aggregate Maturities

Aggregate maturities of the Company’s long-term debt, excluding debt discounts, as of September 30, 2021, are as follows:


(thousands of U.S. dollars)
2021	$	—
2022	—
2023	450
2024	—
2025	—
Thereafter	1,763,100
Total	$	1,763,550

As referenced above, the Company utilized its IPO proceeds toward prepaying the Second Lien Notes in full as well as prepaying a portion of the Term Loan. The Term Loan prepayment amount eliminated all subsequent scheduled and outstanding repayments of the term borrowings resulting in no remaining short-term commitments.

10.Income Taxes

Income tax expense is provided on an interim basis based upon our estimate of the annual effective income tax rate. In determining the estimated annual effective income tax rate, we analyze various factors, including projections of our annual earnings and the taxing jurisdictions where the earnings will occur, the impact of state and local taxes, our ability to utilize tax credits and net operating loss carryforwards and available tax planning alternatives.

Our effective tax rates were 33.2 % and 30.7% for the three and nine months ended September 30, 2021, respectively, compared to (207.7)% and (255.9)% for the three and nine months ended September 30, 2020, respectively.

Income tax expense for the three months ended September 30, 2021 differed from the statutory rate primarily due to the impact of the foreign rate differential, global intangible low-tax income (“GILTI”) and a net increase in the interest expense valuation allowance. Provision for income taxes for the three months ended September 30, 2020 differed from the statutory rate primarily due to the foreign rate differential, GILTI, non-deductible expenses as well as the impact of the 2020 Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), which increased the limitation on interest expense deductions and resulted in a valuation allowance reversal.

Income tax expense for the nine months ended September 30, 2021 differed from the statutory rate primarily due to the impact of the foreign rate differential, GILTI, a net increase in the interest expense valuation allowance, and a discrete item pertaining to an income tax rate change in the United Kingdom. This was partially offset by an additional discrete item in the first quarter of 2021, which reversed the valuation allowance on deferred tax assets related to certain asset retirement obligations.

Our effective tax rates for the three and nine months ended September 30, 2020 differed from the statutory rate due to the impact of GILTI, the foreign rate differential, non-deductible expenses as well as the impact of the CARES Act. The CARES Act increased the limitation on the deductibility of interest expense from 30% to 50% for tax years beginning in 2019 or 2020, among other provisions. The increased limitation resulted in a current tax benefit for the nine months ended September 30, 2020 of $8.7 million. The increased limitation also resulted in a $5.6 million valuation allowance reversal in the nine months ended September 30, 2020.

11.Employee Benefits

The Company sponsors various post-employment benefit plans including, in certain countries outside the U.S., defined benefit and defined contribution pension plans, retirement compensation arrangements, and plans that provide extended health care coverage to retired employees, the majority of which relate to Nordion.

Notes to Consolidated Financial Statements

Defined benefit pension plan

The interest cost and expected return on plan assets are recorded in “Other income, net” and the service cost component is included in the same financial statement line item as the applicable employee’s wages in the Consolidated Statements of Operations and Comprehensive Income (Loss). The components of net periodic pension cost for the defined benefit plans for the three and nine months ended September 30, 2021 and 2020 were as follows:


	Three Months Ended September 30,				Nine Months Ended September 30,
(thousands of U.S. dollars)	2021		2020		2021		2020
Service cost	$	300	$	278	$	905	$	821

Net periodic benefit	$	(1,386)	$	(1,127)	$	(4,186)	$	(3,329)

Other benefit plans

Other benefit plans include a supplemental retirement arrangement, a retirement and termination allowance, and post-retirement benefit plans, which include contributory health and dental care benefits and contributory life insurance coverage. All but one, non-pension post-employment benefit plans are unfunded. The components of net periodic pension cost for the other benefit plans for the three and nine months ended September 30, 2021 and 2020 were as follows:


	Three Months Ended September 30,				Nine Months Ended September 30,
(thousands of U.S. dollars)	2021		2020		2021		2020
Service cost	$	7	$	7	$	21	$	21

Amortization of net actuarial loss	9		13		26		39
Net periodic benefit cost	$	75	$	94	$	226	$	278

We currently expect funding requirements of approximately $2.8 million in each of the next five years to fund the regulatory solvency deficit, as defined by Canadian federal regulation, which require solvency testing on defined benefit pension plans.

The Company may obtain a qualifying letter of credit for solvency payments, up to 15% of the market value of solvency liabilities as determined on the valuation date, instead of paying cash into the pension fund. As of September 30, 2021, and December 31, 2020, we had letters of credit outstanding relating to the defined benefit plans totaling $44.5 million and $41.3 million, respectively. The actual funding requirements over the five-year period will be dependent on subsequent annual actuarial valuations. These amounts are estimates, which may change with actual investment performance, changes in interest rates, any pertinent changes in Canadian government regulations and any voluntary contributions.

12.Related Parties

We do business with a number of companies affiliated with Warburg Pincus and GTCR, which we refer to collectively as the “Sponsors,” who continue to have substantial control over us. All transactions with these companies have been conducted in the ordinary course of our business and are not material to our operations.

14.Share-Based Compensation

Pre-IPO Awards

Restricted stock distributed in respect of pre-IPO Class B-1 time vesting units vests on a daily basis pro rata over a five-year vesting period (20% per year) beginning on the original vesting commencement date of the corresponding Class B-1 time vesting units, subject to the grantee’s continued services through each vesting date. Upon the occurrence of a change in control

Notes to Consolidated Financial Statements

of the Company, all then outstanding unvested shares of our common stock distributed in respect of Class B-1 Units will become vested as of the date of consummation of such change in control, subject to the grantee’s continued services through the consummation of the change in control.

Restricted stock distributed in respect of pre-IPO Class B-2 Units (which were considered performance vesting units) are scheduled to vest only upon satisfaction of certain thresholds. These units generally vest as of the first date on which (i) our Sponsors have received actual cash proceeds in an amount equal to or in excess of at least two and one-half times their invested capital in Sotera Health Topco Parent, L.P. (of which the Company was a direct wholly owned subsidiary prior to the IPO) and (ii) the Sponsors’ internal rate of return exceeds twenty percent, subject to such grantee’s continued services through such date. In the event of a change in control of the Company, any outstanding shares of our common stock distributed in respect of Class B-2 Units that remain unvested immediately following the consummation of such a change in control of the Company shall be immediately canceled and forfeited without compensation. Stock based compensation expense attributed to the pre-IPO Class B-2 awards was recorded in the fourth quarter of 2020 as the related performance conditions were considered probable of achievement and the implied service conditions were met. As of September 30, 2021, these awards remain unvested.

We recognized $0.7 million and $0.9 million of share-based compensation expense related to the pre-IPO Class B-1 awards for the three months ended September 30, 2021 and 2020, and $2.0 million and $4.0 million for the nine months ended September 30, 2021 and 2020, respectively.

A summary of the activity for the nine months ended September 30, 2021 related to the restricted stock awards distributed to the Company service providers in respect of the pre-IPO awards (Class B-1 and B-2 Units) is presented below:


	Restricted Stock - Pre- IPO B-1	Restricted Stock - Pre- IPO B-2
Unvested at December 31, 2020	2,201,239	2,323,333

2020 Omnibus Incentive Plan

We maintain a long-term incentive plan (the “2020 Omnibus Incentive Plan” or the “2020 Plan”) that allows for grants of incentive stock options to employees (including employees of any of our subsidiaries), nonstatutory stock options, restricted stock awards (“RSAs”), restricted stock units (“RSUs”) and other cash-based, equity-based or equity-related awards to employees, directors, and consultants, including employees or consultants of our subsidiaries.

We recognized $2.9 million ($1.3 million for stock options and $1.6 million for RSUs) of share-based compensation expense for these awards for the three months ended September 30, 2021, and $8.5 million ($3.9 million for stock options and $4.6 million for RSUs) for the nine months ended September 30, 2021 in our Consolidated Statements of Operations and Comprehensive Income (Loss), in “Selling, general and administrative expenses.”

15.Earnings Per Share

Basic earnings per share represents the amount of income attributable to each common share outstanding. Diluted earnings per share represents the amount of income attributable to each common share outstanding adjusted for the effects of potentially dilutive common shares. Potentially dilutive common shares include stock options and other stock-based awards. In the periods where the effect would be antidilutive, potentially dilutive common shares are excluded from the calculation of diluted earnings per share.

In periods in which the Company has net income, earnings per share is calculated using the two-class method. This method is required as unvested restricted stock distributed in respect of pre-IPO Class B-1 and B-2 awards have the right to receive non-forfeitable dividends or dividend equivalents if the Company were to declare dividends on its common stock. Pursuant to the two-class method, earnings for each period are allocated on a pro-rata basis to common stockholders and unvested pre-IPO Class B-1 and B-2 restricted stock awards. Diluted earnings per share is computed using the more dilutive of (a) the two-class method, or (b) treasury stock method, as applicable, to the potentially dilutive instruments.

In periods in which the Company has a net loss, the two-class method is not applicable because the pre-IPO Class B-1 and B-2 restricted stock awards do not participate in losses.

For the three and nine months ended September 30, 2020, there were no potentially dilutive common shares outstanding.

16.Commitments and Contingencies

From time to time, we may be subject to various lawsuits and other claims, as well as gain contingencies, in the ordinary course of our business. In addition, from time to time, we receive communications from government or regulatory agencies concerning investigations or allegations of noncompliance with laws or regulations in jurisdictions in which we operate.

We establish reserves for specific liabilities in connection with regulatory and legal actions that we determine to be both probable and reasonably estimable. No material amounts have been accrued in our consolidated financial statements with respect to any loss contingencies. In certain of the matters described below, we are not able to make a reasonable estimate of any liability because of the uncertainties related to the outcome and/or the amount or range of loss. While it is not possible to determine the ultimate disposition of each of these matters, we do not expect that the ultimate resolution of pending regulatory and legal matters in future periods, including the matters described below, will have a material effect on our financial condition or results of operations. Despite the above, the Company may incur material defense and settlement costs, diversion of management resources and other adverse effects on our business, financial condition, or results of operations.

FM Global Business Interruption Claim (NRU Outage)

Nordion, due to the shutdown of AECL’s NRU reactor in 2009, suffered a cessation of supply of radioisotopes and business interruption loss. Nordion, by Statement of Claim dated October 22, 2010, issued in Ontario Superior Court an action against the insurer, Factory Mutual Insurance Company (FM Global), claiming $25.0 million USD in losses resulting from the shutdown of AECL’s reactor and its inability to supply radioisotopes through the specified period of approximately 15 months. FM Global objected to Nordion’s claim.

On March 30, 2020, Nordion received a favorable judgment in the amount of $25.0 million USD, plus pre-judgment interest, for a total judgment value of $39.8 million USD, or $56.4 million CAD based on exchange rates approved by the trial court. In addition, costs and disbursements were assessed and awarded by the trial court in favor of Nordion in the approximate amount of $1.3 million CAD ($1.0 million USD). FM Global appealed the judgment. On September 3, 2021 the Court of Appeal ruled in favor of FM Global, setting aside the trial court decision, denying insurance coverage to Nordion, and awarding costs and

Ethylene Oxide Tort Litigation - Illinois

Sotera Health LLC, Sterigenics U.S., LLC, GTCR, LLC and other parties are defending personal injury lawsuits related to Sterigenics’ Willowbrook, Illinois operations. Specifically, approximately 770 plaintiffs allege that they suffered personal injuries including cancer and other diseases, or wrongful death, resulting from purported emissions and releases of ethylene oxide (“EO”) from the Willowbrook facility. Additional derivative claims are alleged on behalf of other individuals related to these personal injury plaintiffs. Plaintiffs seek damages in an amount to be determined by the trier of fact. Sterigenics denies these allegations and intends to vigorously defend against these claims. These personal injury lawsuits began to be filed in September 2018, and most of the pending cases were filed before August 21, 2020, the second anniversary of the publication of governmental reports alleging health risks related to the Willowbrook facility. In October 2019 the lawsuits were consolidated for pre-trial purposes by the Cook County Circuit Court, Illinois (the “Consolidated Case”).

All plaintiffs in the Consolidated Case filed an Amended Master Complaint on April 16, 2021, including claims against Griffith Foods International, Inc. (“Griffith”). Griffith filed a motion to dismiss and all other defendants filed answers to the Complaint. The answer of Sterigenics included counterclaims for contribution against Griffith. Plaintiffs have not yet made any specific damages claims.

Written and deposition fact discovery in the Consolidated Case is scheduled to conclude by February 1, 2022.

Trials in three of the individual cases included in the Consolidated Case have been scheduled for July 18, 2022, September 12, 2022 and November 7, 2022.

Ethylene Oxide Tort Litigation – Georgia

Sotera Health LLC, Sterigenics U.S., LLC and other parties are being defended and indemnified in a lawsuit filed on May 19, 2020 in the State Court of Cobb County, Georgia by 53 employees of a contract sterilization customer of Sterigenics (“Indemnitor”). Plaintiffs claim personal injuries resulting from alleged exposure to residual EO while working at the Indemnitor’s distribution center in Lithia Springs, Georgia, allege they were unaware that they were being exposed to EO in Indemnitor’s workplace and seek damages. Discovery is stayed until motions to dismiss the operative complaint are decided.

In May 2020, the Cobb County, Georgia Board of Tax Assessors reduced certain residential property value assessments around the Sterigenics Atlanta facility by 10% citing an “Epd-identified environmental issue,” without supporting market data. On August 14, 2020, Sterigenics U.S., LLC filed a lawsuit against members of the Cobb County Board of Tax Assessors in the U.S. District Court for the Northern District of Georgia, seeking a declaration that the reduction in property value assessments is arbitrary and unlawful and is causing Sterigenics reputational and imminent economic harm. On February 5, 2021 the Court issued an order finding that Sterigenics lacks standing to obtain the relief sought and dismissed the case. Sterigenics has appealed that decision to the 11th Circuit Court of Appeals.

Since August 17, 2020, 41 plaintiffs have filed lawsuits against Sotera Health LLC, Sterigenics U.S., LLC and other parties in the State Court of Cobb County, Georgia and the State Court of Gwinnett County, Georgia alleging that they suffered personal injuries resulting from emissions and releases of EO from Sterigenics’ Atlanta facility. Additional derivative claims are alleged on behalf of other individuals related to these personal injury plaintiffs. Our subsidiaries are also defendants in two lawsuits alleging that the Atlanta facility has devalued and harmed plaintiffs’ use of real properties they own in Smyrna, Georgia and caused other damages. These personal injury and property devaluation Plaintiffs seek various forms of relief including damages. Ten of the personal injury lawsuits pending in Cobb County have been consolidated for pretrial purposes, governed by a phased case management order pursuant to which general causation issues are scheduled to be determined by November 15, 2022, specific causation issues are scheduled to be determined by March 20, 2023, and one case is scheduled to be trial-ready by July 2023. The remaining personal injury and property devaluation cases are in various early stages of pleadings and motions practice and fact discovery. Additional lawsuits relating to Sterigenics’ Atlanta facility are expected to be filed during November 2021.

Consent Order Allowing Georgia Facility’s Normal Operations & Related Litigation

On August 7, 2019, Sterigenics U.S., LLC entered into a voluntary Consent Order with the Georgia Environmental Protection Division (“EPD”) under which Sterigenics agreed to install emissions reduction enhancements at its Atlanta facility to further reduce the facility’s EO emissions below already permitted levels. Sterigenics voluntarily suspended operations at the facility in early September 2019 to expedite completion of the enhancements. Installation of these enhancements is complete and Sterigenics successfully tested the enhanced emissions controls in cooperation with EPD during the second quarter of 2020 while the facility was in operation.

In October 2019, while Sterigenics had voluntarily suspended the facility’s operations, Cobb County, Georgia officials asserted that the facility had an incorrect “certificate of occupancy” and could not resume operations without obtaining a new certificate of occupancy after a third-party code compliance review they required.

After the Cobb County officials would not allow Sterigenics to resume operations, on March 30, 2020, Sterigenics U.S., LLC filed a lawsuit in the United States District Court for the Northern District of Georgia against Cobb County, Georgia and Cobb County officials Nicholas Dawe and Kevin Gobble. In the lawsuit, Sterigenics sought immediate injunctive relief and permanent declaratory relief to resume normal operations of the Atlanta facility in the interest of public health and on the basis that the positions asserted by Cobb County were unfounded. On April 1, 2020 the Court entered a Temporary Restraining Order prohibiting Cobb County officials from precluding or interfering with the facility’s normal operations. On April 8, 2020, the Court entered a Consent Order extending the Temporary Restraining Order and allowing the facility to continue normal operations until entry of a final judgment in the case. Defendants filed a motion to dismiss the claims. On November 9, 2020, the Court held a hearing and denied the motion to dismiss. The parties are conducting discovery, which is scheduled to end in April 2022. A settlement conference is scheduled to be held by April 27, 2022.

Ethylene Oxide Litigation – New Mexico

On December 22, 2020, the New Mexico Attorney General filed a lawsuit in the Third Judicial District Court, Doña Ana County, New Mexico (the “Third Judicial District”) against the Company, Sterigenics U.S., LLC and other subsidiaries alleging that emissions of EO from Sterigenics’ sterilization facility in Santa Teresa, New Mexico constitute a public nuisance and have deteriorated the air quality in Santa Teresa and surrounding communities and materially contributed to increased health risks suffered by residents of those communities. The Complaint asserts claims for public nuisance, negligence, strict liability, violations of New Mexico’s Public Nuisance Statute and Unfair Practices Act and a request for a temporary restraining order and preliminary injunctive relief.

On June 29, 2021, the Court entered an Order Granting Preliminary Injunction (the “Order”). The Order does not require closure of the facility, but prohibits Sterigenics from allowing any uncontrolled emission or release of EO from the facility, including prohibitions on leaving doors open when not in use and allowing EO to escape through point sources prior to filtration or processing through emission controls. Sterigenics promptly took steps to monitor its compliance with the Order. The Order instructed the parties to discuss a protocol to monitor Sterigenics’ compliance and, if agreement could not be reached, to request a hearing so the Court can determine a monitoring protocol and how the costs of monitoring will be paid. In July 2021, the parties conferred but could not reach agreement.

On October 28, 2021 the Court held a hearing on the parties’ positions on an appropriate protocol to monitor Sterigenics’ compliance with the Order and how the costs of monitoring will be paid. A ruling is expected before January 2022. A motion challenging the Court’s jurisdiction over the Company and certain other defendants has been held in abeyance until the completion of jurisdictional discovery, and all other motions to dismiss have been denied. The parties are conducting fact discovery.

Before this lawsuit was filed, Sterigenics was working to implement additional emission control enhancements at the Santa Teresa facility to further reduce EO emissions beyond permitted levels. Sterigenics has received the necessary permits from the New Mexico Environment Department and Doña Ana County for implementation of these additional emission control enhancements.

Notes to Consolidated Financial Statements

Our insurance for litigation related to alleged environmental liabilities, like the litigation pending in Illinois, Georgia and New Mexico described above has limits of $10.0 million per occurrence and $20.0 million in the aggregate. The per occurrence limit related to the Willowbrook, Illinois litigation was fully utilized by June 30, 2020. The remaining $10.0 million limit is currently being utilized for occurrences related to the EO litigation in Georgia and New Mexico described above. As of September 30, 2021, we have utilized approximately $2.2 million of the remaining $10.0 million limit. Our insurance for future alleged environmental liabilities excludes coverage for EO claims.

Additional personal injury, property devaluation or other lawsuits may be filed in the future against us or our subsidiaries relating to Sterigenics’ Willowbrook, Atlanta, Santa Teresa or other EO sterilization facilities. The Company, Sterigenics U.S., LLC and other Company subsidiaries intend to defend themselves vigorously in all such current or future EO litigation.

While an adverse outcome in one or more of the proceedings could have a material adverse effect on our business, financial condition and results of operations, no contingency reserve has been reflected in our consolidated financial statements as a loss is not deemed probable or a loss or range of losses is not reasonably estimable at this time.

17.Financial Instruments and Financial Risk

Derivative Instruments

We do not use derivatives for trading or speculative purposes and are not a party to leveraged derivatives.

Derivatives Designated in Hedge Relationships

During the third quarter of 2019, we entered into two interest rate swap agreements to hedge our exposure to interest rate movements and to manage interest expense related to our then outstanding variable-rate debt. The notional amount of the interest rate swap agreements totaled $1,000.0 million. These swaps were designated as cash flow hedges and were designed to hedge the variability of cash flows attributable to changes in LIBOR, the benchmark interest rate being hedged. We received interest at one-month LIBOR and paid a fixed interest rate under the terms of the swap agreement. The swap agreements terminated on August 31, 2020.

Derivatives Not Designated in Hedge Relationships

In October 2017, we entered into two interest rate cap agreements with a total notional amount of $400.0 million for a total option premium of $0.6 million; these agreements terminated on September 30, 2020. The interest rate caps limited the Company’s cash flow exposure related to LIBOR under the variable rate Term Loan borrowings to 3.0%.

In June 2020, SHH entered into two interest rate cap agreements with notional amounts of $1,000.0 million and $500.0 million, respectively, for a total option premium of $0.3 million. These instruments were initially scheduled to terminate on August 31, 2021 and February 28, 2022, respectively. The interest rate caps limit our cash flow exposure related to the LIBOR base rate under a portion of our variable rate borrowings to 1.0%. In February 2021, we amended the two interest rate cap agreements referenced above to reduce the strike rate from 1.0% to 0.5%, and extend the termination date of the $1,000.0 million notional cap to September 30, 2021. Premiums paid to amend the interest rate caps were immaterial. We also entered into two additional interest rate cap agreements in February 2021 with a combined notional amount of $1,000.0 million, for a total option premium of $0.4 million. These instruments are effective September 30, 2021, and will terminate on December 31, 2022. The amended and new interest rate caps limit our cash flow exposure related to LIBOR under a portion of our variable rate borrowings to 0.5%.

The interest rate caps were entered into to manage economic risks associated with our variable rate borrowings, but were not designated in hedge relationships. These instruments are recorded at fair value on the Consolidated Balance Sheets, with any changes in the value being recorded in “Interest expense, net” in the Consolidated Statements of Operations and Comprehensive Income (Loss).

The Company also entered into foreign currency forward contracts to manage foreign currency exchange rate risk of our intercompany loans in certain of our international subsidiaries. The foreign currency forward contracts expire on a monthly basis. The fair value of the outstanding foreign currency forward contracts was zero as of September 30, 2021 and December 31, 2020, respectively.

Embedded Derivatives

We have embedded derivatives in certain of our customer and supply contracts as a result of the currency of the contract being different from the functional currency of the parties involved. Changes in the fair value of the embedded derivatives are recognized in “Other income, net” in the Consolidated Statements of Operations and Comprehensive Income (Loss).

The following table provides a summary of the notional and fair values of our derivative instruments:


	September 30, 2021							December 31, 2020
(in U.S. Dollars; notional in millions, fair value in thousands)				Fair Value						Fair Value
	Notional Amount			Derivative Assets		Derivative Liabilities		Notional Amount		Derivative Assets		Derivative Liabilities
Derivatives not designated as hedging instruments:
Interest rate caps	$	2,500.0	(a)	$	201	$	—	$	1,500.0	$	7	$	—
Embedded derivatives	77.9		(b)	—		281		83.3		—		670
Total	$	2,577.9		$	201	$	281	$	1,583.3	$	7	$	670

(a)$1,000.0 million notional amount of interest rate caps terminated on September 30, 2021.

(b)Represents the total notional amounts for certain of the Company’s supply and sales contracts accounted for as embedded derivatives.

The interest rate caps and embedded derivative assets are included in “Prepaid expenses and other current assets” or “Other assets” on the Consolidated Balance Sheets depending upon their respective maturity dates. Embedded derivative liabilities are included in “Accrued liabilities” on the Consolidated Balance Sheets.

The following tables summarize the activities of our derivative instruments for the periods presented, and the line item they are recorded in the Consolidated Statements of Operations and Comprehensive Income (Loss):

Credit Risk

Certain of our financial assets, including cash and cash equivalents, are exposed to credit risk.

We are also exposed, in our normal course of business, to credit risk from our customers. As of September 30, 2021 and December 31, 2020, accounts receivable was net of an allowance for uncollectible accounts of $1.0 million and $0.7 million, respectively.

Credit risk on financial instruments arises from the potential for counterparties to default on their contractual obligations to us. We are exposed to credit risk in the event of non-performance, but do not anticipate non-performance by any of the counterparties to our financial instruments. We limit our credit risk by dealing with counterparties that are considered to be of high credit quality. In the event of non-performance by counterparties, the carrying value of our financial instruments represents the maximum amount of loss that would be incurred.

Fair Value Hierarchy

The fair value of our financial instruments is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The valuation techniques we would use to determine such fair values are described as follows: Level 1—fair values determined by inputs utilizing quoted prices in active markets for identical assets or liabilities; Level 2—fair values based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable; Level 3—fair values determined by unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants.

The following table discloses the fair value of our financial assets and liabilities:


As of September 30, 2021			Fair Value
(thousands of U.S. dollars)	Carrying Amount		Level 1		Level 2		Level 3
Derivatives not designated as hedging instruments(a)
Interest rate caps	$	201	$	—	$	201	$	—

Notes to Consolidated Financial Statements

(a)Derivatives that are not designated as hedging instruments are measured at fair value with gains or losses recognized immediately in the Consolidated Statements of Operations and Comprehensive Income (Loss). Interest rate caps are valued using pricing models that incorporate observable market inputs including interest rate and yield curves. Embedded derivatives are valued using internally developed models that rely on observable market inputs including foreign currency forward curves.

(b)Carrying amounts of long-term debt instruments are reported net of discounts and debt issuance costs. The estimated fair value of these instruments is based on information provided by the agent under the Company’s senior secured credit facility. Fair value approximates carrying value for “Other long-term debt.”

(c)Fair value approximates carrying value.

18.Segment Information

We identify our operating segments based on the way we manage, evaluate and internally report our business activities for purposes of allocating resources and assessing performance. We have three reportable segments: Sterigenics, Nordion and Nelson Labs.

OVERVIEW

We are a leading global provider of mission-critical end-to-end sterilization solutions, lab testing and advisory services for the healthcare industry. We are driven by our mission: Safeguarding Global Health®. We provide end-to-end sterilization as well as microbiological and analytical lab testing and advisory services to help ensure that medical, pharmaceutical and food products are safe for healthcare practitioners, patients and consumers in the United States and around the world. Our services are an essential aspect of our customers’ manufacturing process and supply chains, helping to ensure sterilized medical products reach healthcare practitioners and patients. Most of these services are necessary for our customers to satisfy applicable government requirements.

We serve our customers throughout their product lifecycles, from product design to manufacturing and delivery, helping to ensure the sterility, effectiveness and safety of their products for the end user. We operate across two core businesses: sterilization services and lab services. The combination of Sterigenics, our terminal sterilization business, and Nordion, our Co-60 supply business, makes us the only vertically integrated global gamma sterilization provider in the sterilization industry. For financial reporting purposes, our sterilization services business consists of two reportable segments, Sterigenics and Nordion, and our lab services business consists of one reportable segment, Nelson Labs.

For the three and nine months ended September 30, 2021, respectively, we recorded net revenues of $226.2 million and $690.2 million, net income of $27.4 million and $81.1 million, Adjusted Net Income of $58.7 million and $181.9 million, and Adjusted EBITDA of $116.7 million and $356.6 million. For the definition of Adjusted Net Income and Adjusted EBITDA and the reconciliation of these non-GAAP measures from net income (loss), please see “Non-GAAP Financial Measures.”

STRATEGIC DEVELOPMENTS AND KEY FACTORS AFFECTING OUR RESULTS OF OPERATIONS

The following summarizes strategic developments and key factors that have underpinned our operating results for the three and nine months ended September 30, 2021 and may continue to affect our performance and financial condition in future periods.

•Driving organic growth. During the three and nine months ended September 30, 2021, we continued to make investments to expand capacity and implement EO facility enhancements in our Sterigenics business and expand our cobalt development resources in our Nordion business. In addition, we continue to expand capacity to meet demand for microbiological testing and extractables and leachables testing in our Nelson Labs business.

•Disciplined and strategic M&A activity. We continue to pursue strategic acquisitions to grow our footprint and expand our capabilities. Most recently, in November 2021, we acquired Regulatory Compliance Associates Inc., for approximately $31 million, bringing expertise in regulatory, quality and compliance advisory services to our Expert Advisory Services team. On March 8, 2021, we acquired BioScience Laboratories, LLC (“BioScience Labs”) with one location in Bozeman, Montana. BioScience Labs is a provider of outsourced topical antimicrobial and virology product testing in the pharmaceutical, medical device, and consumer products industries. BioScience Labs’ expertise in analytical testing and clinical trial services will complement Nelson Labs’ existing strengths in antimicrobial and virology testing. In July 2020, we acquired Iotron Industries Canada, Inc. (“Iotron”), an E-beam processing services and equipment provider.

Additionally, on May 18, 2021, we completed the purchase of the outstanding noncontrolling interests of 15% and 33% of our two China subsidiaries, respectively, for a total purchase price of $8.6 million. On March 11, 2021, we completed the acquisition of the remaining 15% ownership of Nelson Labs Fairfield for $12.4 million. Pursuant to the terms of the transaction, we acquired 85% of the equity interests of Nelson Labs Fairfield in August 2018 and were required to acquire the 15% noncontrolling interest within three years from the date of the acquisition.

•Borrowings and financing costs. A combination of lower outstanding borrowings and reduced pricing on our debt resulted in a reduction in cash interest expense for the three and nine months ended September 30, 2021 compared to

the three and nine months ended September 30, 2020. On January 20, 2021 we amended our Term Loan to reduce the interest rate spread over LIBOR from 4.50% to 2.75%, and the LIBOR floor from 1.00% to 0.50%. The changes resulted in an effective reduction in current interest rates of 2.25%. We expect the amendment to provide additional cash interest savings of approximately $40.0 million per year based on the outstanding principal balance as of the date of the amendment. Interest savings in 2021 will be offset by cash and non-cash charges associated with the repricing amendment. In connection with this transaction, we wrote off approximately $11.3 million in debt issuance costs and debt discounts and incurred approximately $2.9 million in costs directly related to the refinancing transaction. On March 26, 2021, we amended our Revolving Credit Facility to reduce the interest rate spread over LIBOR applicable to revolving loans from 3.50% to 2.75%.

In addition, on August 27, 2021, we redeemed in full all of the $100.0 million aggregate principal amount of the senior secured first lien notes due 2026 (“First Lien Notes”). In connection with this redemption, the Company paid a $3.0 million early redemption premium and wrote off $3.4 million of debt issuance and discount costs. We expect the redemption to provide additional cash interest savings of approximately $7.0 million per year.

• Impacts of our IPO and other public company costs. As a newly public company, we continue to incur certain expenses on an ongoing basis that we did not incur as a private company including third-party and internal resources related to accounting, auditing, Sarbanes-Oxley Act compliance, legal, and investor and public relations expenses. These costs are primarily classified as selling, general and administrative (“SG&A”) expenses. We continue to dedicate internal resources, hire additional personnel, and engage outside consultants to assess and document the adequacy of internal controls over financial reporting. In addition, in March 2021, we incurred costs related to a secondary offering of 25 million shares of our common stock offered by selling stockholders, which included certain affiliates of Warburg Pincus LLC and GTCR, LLC as well as certain current and former members of management of the Company.

•Litigation related costs and exit activities. In connection with the ongoing litigation related to our Willowbrook, Illinois, Atlanta, Georgia and Santa Teresa, New Mexico facilities, as described in Note 16, “Commitments and Contingencies”, we recorded costs of $9.4 million and $33.5 million for the three and nine months ended September 30, 2021, respectively, relating to legal and other professional service costs, as well as $0.3 million and $1.6 million, respectively, related to the closure of the Willowbrook, Illinois facility.

•Impact of COVID-19 pandemic. We remain subject to risks and uncertainties as a result of the COVID-19 pandemic. Our business continuity plans remain in effect and we have maintained certain measures to decrease exposure risk and manage our supply chain for critical materials. The extent to which our operations will continue to be impacted by the pandemic will largely depend on future developments, which still remain uncertain and cannot be predicted.

(a)Adjusted Net Income and Adjusted EBITDA are non-GAAP financial measures. For more information regarding our calculation of Adjusted Net Income and Adjusted EBITDA, including information about their limitations as tools for analysis and a reconciliation of net income, the most directly comparable financial measure calculated and presented in accordance with GAAP, to Adjusted Net Income and Adjusted EBITDA, please see the reconciliation included below in “Non-GAAP Financial Measures.”

Total Net Revenues

The following table compares our revenues by type for the three months ended September 30, 2021 to the three months ended September 30, 2020.


(thousands of U.S. dollars)
Net revenues for the three months ended September 30,	2021		2020		$ Change		% Change

Service	$	200,499	$	182,176	$	18,323	10.1	%
Product	25,665		17,852		7,813		43.8	%
Total net revenues	$	226,164	$	200,028	$	26,136	13.1	%

Net revenues were $226.2 million in the three months ended September 30, 2021, an increase of $26.1 million, or 13.1%, as compared with the three months ended September 30, 2020. Excluding the impact of foreign currency exchange rates, net revenues in the three months ended September 30, 2021 increased approximately 11.8% compared with the three months ended September 30, 2020.

Service revenues

Service revenues increased $18.3 million, or 10.1%, to $200.5 million in the three months ended September 30, 2021 as compared to $182.2 million in the three months ended September 30, 2020. The increase in net service revenue was driven by $10.8 million of organic sales volume growth in the Sterigenics segment and $5.0 million from the incremental contributions of the recent Iotron and BioScience Labs acquisitions. Service revenue growth also benefited from favorable pricing of $4.7 million and $1.7 million in the Sterigenics and Nelson Labs segments, respectively. Offsetting these increases was a decline in revenue of $4.6 million related to the testing of personal protective equipment in the Nelson Labs segment.

Product revenues

Product revenues increased $7.8 million, or 43.8%, to $25.7 million in the three months ended September 30, 2021 as compared to $17.9 million in the three months ended September 30, 2020. The increase in product revenues was attributable to higher organic sales volumes of $5.5 million, largely driven by shipments of industrial use Co-60 in our Nordion segment, and the contribution of favorable pricing and changes in foreign currency exchange rates of $1.3 million and $1.0 million, respectively.

Total Cost of Revenues

The following table compares our cost of revenues by type for the three months ended September 30, 2021 to the three months ended September 30, 2020.


(thousands of U.S. dollars)
Cost of revenues for the three months ended September 30,	2021		2020		$ Change		% Change

Service	$	88,349	$	83,697	$	4,652	5.6	%
Product	12,229		8,820		3,409		38.7	%
Total cost of revenues	$	100,578	$	92,517	$	8,061	8.7	%

Total cost of revenues accounted for approximately 44.5% and 46.3% of our consolidated net revenues for the three months ended September 30, 2021 and 2020, respectively.

Cost of service revenues

Cost of service revenues increased $4.7 million, or 5.6%, for the three months ended September 30, 2021 as compared to the three months ended September 30, 2020. The increase was largely attributable to overall increases in direct costs in support of the service revenue growth within the Sterigenics segment cited above. The increase was also driven by a $2.1 million contribution from the Iotron and BioScience Labs acquisitions and a $0.7 million unfavorable impact from changes in foreign currency exchange rates within foreign subsidiaries across all segments.

Cost of product revenues

Cost of product revenues increased $3.4 million, or 38.7%, for the three months ended September 30, 2021 as compared to the three months ended September 30, 2020. The increase was primarily a result of incremental direct costs in support of the product revenue volume growth in the Nordion segment.

Operating Expenses

The following table compares our operating expenses for the three months ended September 30, 2021 to the three months ended September 30, 2020:


(thousands of U.S. dollars)
Operating expenses for the three months ended September 30,	2021		2020		$ Change		% Change

Selling, general and administrative expenses	$	44,038	$	45,632	$	(1,594)	(3.5)	%
Amortization of intangible assets	15,877		14,849		1,028		6.9	%

Total operating expenses	$	59,915	$	60,481	$	(566)	(0.9)	%

Operating expenses accounted for approximately 26.5% and 30.2% of our consolidated net revenues for the three months ended September 30, 2021 and 2020, respectively.

SG&A

SG&A decreased $1.6 million, or 3.5%, for the three months ended September 30, 2021 as compared to the three months ended September 30, 2020. The change was largely driven by the following:

•$3.4 million offset to SG&A related to the settlement of an insurance claim for Nordion that existed at the time of our acquisition of the business in 2014;

•$2.3 million decrease in legal and other professional services expense associated with Sterigenics EO litigation.;

Offsetting these decreases was an increase in share-based compensation expense of $2.7 million related to our 2020 Omnibus Incentive Plan.

Amortization of intangible assets

Amortization of intangible assets was $15.9 million for the three months ended September 30, 2021, or 6.9% above the three months ended September 30, 2020. The change was primarily attributable to amortization on newly acquired intangible assets related to the Iotron and BioScience Labs acquisitions.

Interest Expense, Net

Interest expense, net decreased $37.2 million, or 67.2%, for the three months ended September 30, 2021 as compared to the three months ended September 30, 2020. The decrease was due to lower outstanding debt for the three months ended September 30, 2021 driven largely by the paydown of the Term Loan and Second Lien Notes with IPO proceeds in the fourth quarter of 2020, the redemption of the First Lien Notes in August 2021, and lower interest rates subsequent to the January 2021 Term Loan refinancing. The weighted average interest rate on our outstanding debt was 3.25% and 6.45% at September 30, 2021 and 2020, respectively.

Foreign Exchange Loss (Gain)

Foreign exchange loss was $0.8 million for the three months ended September 30, 2021 as compared to a gain of $4.6 million in the three months ended September 30, 2020. The foreign exchange loss (gain) in our Consolidated Statements of Operations and Comprehensive Income (Loss) relates primarily to U.S. dollar denominated intercompany indebtedness with certain of our European and Canadian subsidiaries.

Other Income, Net

Other income, net was $0.7 million for the three months ended September 30, 2021 compared to $3.1 million for the three months ended September 30, 2020. The fluctuation was driven by changes in the fair value of the embedded derivatives in Nordion’s contracts. We recorded an unrealized loss on embedded derivatives of $1.2 million for the three months ended

September 30, 2021 as compared to an unrealized gain on embedded derivatives of $1.5 million for the three months ended September 30, 2020.

Provision (Benefit) for Income Taxes

Provision for income tax increased $14.9 million to a net provision of $13.7 million for the three months ended September 30, 2021 as compared to $1.2 million benefit in the three months ended September 30, 2020. The change was principally attributable to pre-tax income of $41.1 million in the three months ended September 30, 2021 compared to a pretax loss of $0.6 million for the three months ended September 30, 2020.

Provision for income taxes for the three months ended September 30, 2021 differed from the statutory rate primarily due to the impact of the foreign rate differential, global intangible low-tax income (“GILTI”) and a net increase in the interest expense valuation allowance. Provision for income taxes for the three months ended September 30, 2020 differed from the statutory rate primarily due to the foreign rate differential, GILTI, non-deductible expenses as well as the impact of the 2020 Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), which increased the limitation on interest expense deductions and resulted in a valuation allowance reversal.

Net Income, Adjusted Net Income and Adjusted EBITDA

Net income for the three months ended September 30, 2021 was $27.4 million, as compared to net income of $0.6 million for the three months ended September 30, 2020. Adjusted Net Income was $58.7 million for the three months ended September 30, 2021, as compared to $22.0 million for the three months ended September 30, 2020, due to the factors described above. Adjusted EBITDA was $116.7 million for the three months ended September 30, 2021, as compared to $100.5 million for the three months ended September 30, 2020, due to the factors described above. Please see “Non-GAAP Financial Measures” below for a reconciliation of Adjusted Net Income and Adjusted EBITDA to their most directly comparable financial measure calculated and presented in accordance with GAAP.

Total Net Revenues

The following table compares our revenues by type for the nine months ended September 30, 2021 to the nine months ended September 30, 2020.


(thousands of U.S. dollars)
Net revenues for the nine months ended September 30,	2021		2020		$ Change		% Change

Service	$	597,907	$	524,025	$	73,882	14.1	%
Product	92,322		77,288		15,034		19.5	%
Total net revenues	$	690,229	$	601,313	$	88,916	14.8	%

Net revenues were $690.2 million in the nine months ended September 30, 2021, an increase of $88.9 million, or 14.8%, as compared with the nine months ended September 30, 2020. Excluding the impact of foreign currency exchange rates, net revenues in the nine months ended September 30, 2021 increased approximately 12.4% compared with the nine months ended September 30, 2020.

Service revenues

Service revenues increased $73.9 million, or 14.1%, to $597.9 million in the nine months ended September 30, 2021 as compared to $524.0 million in the nine months ended September 30, 2020. The growth in net service revenues was driven by volume growth of $23.1 million in the Sterigenics segment and a $22.5 million increase from the incremental contribution of the Iotron and BioScience Labs acquisitions. In addition, service revenue growth stemmed from favorable pricing of $13.6 million and $5.1 million in the Sterigenics and Nelson Labs segments, respectively, and an $8.6 million benefit from changes in foreign currency exchange rates across all segments. The remainder of the increase was largely attributable to an increase in service revenue volume in the Nordion segment. Offsetting these factors was an overall decline of $2.4 million in revenue related to personal protective equipment testing in the Nelson Labs segment.

Product revenues

Product revenues increased $15.0 million, or 19.5%, to $92.3 million in the nine months ended September 30, 2021 as compared to $77.3 million in the nine months ended September 30, 2020. The increase in product revenues was largely attributable to favorable impacts from pricing and foreign currency exchanges rates of $5.7 million and $5.7 million, respectively, compared to the nine months ended September 30, 2020. The remainder of the increase was driven by volume growth of $3.6 million.

Total Cost of Revenues

The following table compares our cost of revenues by type for the nine months ended September 30, 2021 to the nine months ended September 30, 2020.


(thousands of U.S. dollars)
Cost of revenues for the nine months ended September 30,	2021		2020		$ Change		% Change

Service	$	264,776	$	247,386	$	17,390	7.0	%
Product	40,734		30,932		9,802		31.7	%
Total cost of revenues	$	305,510	$	278,318	$	27,192	9.8	%

Total cost of revenues accounted for approximately 44.3% and 46.3% of our consolidated net revenues for the nine months ended September 30, 2021 and 2020, respectively.

Cost of service revenues

Cost of service revenues increased $17.4 million, or 7.0%, for the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020. The increase was attributable to an incremental contribution of $8.1 million from the Iotron and BioScience Labs acquisitions and approximately $5.0 million of incremental costs associated with increased sales volumes, primarily in the Sterigenics segment, as referenced above. The remainder of the increase is a result of a $4.3 million impact from foreign currency exchange rates on cost of revenues within our foreign subsidiaries.

Cost of product revenues

Cost of product revenues increased $9.8 million, or 31.7%, for the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020. The increase stemmed from a $4.4 million increase in Co-60 supply costs, primarily driven by higher sales volumes. An unfavorable impact from foreign currency exchange rates of $2.8 million also contributed to the increase.

Operating Expenses

The following table compares our operating expenses for the nine months ended September 30, 2021 to the nine months ended September 30, 2020:


(thousands of U.S. dollars)
Operating expenses for the nine months ended September 30,	2021		2020		$ Change		% Change

Selling, general and administrative expenses	$	146,331	$	125,369	$	20,962	16.7	%
Amortization of intangible assets	48,081		43,989		4,092		9.3	%

Total operating expenses	$	194,412	$	169,358	$	25,054	14.8	%

Operating expenses accounted for approximately 28.2% and 28.2% of our consolidated net revenues for the nine months ended September 30, 2021 and 2020, respectively.

SG&A

SG&A increased $21.0 million, or 16.7%, for the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020. The increase was driven primarily by the following:

•$8.3 million in incremental corporate expenses largely attributed to costs associated with being a public company. This includes $5.5 million in incremental costs attributable to public company director and officer liability insurance;

•$8.1 million increase in legal and other professional services expense associated with Sterigenics EO litigation;

•An increase in share-based compensation expense of $6.5 million primarily related to our 2020 Omnibus Incentive Plan;

Offsetting these costs was a $3.4 million settlement of an insurance claim for Nordion that existed at the time of our acquisition of the business in 2014.

Amortization of intangible assets

Amortization of intangible assets was $48.1 million for the nine months ended September 30, 2021, or 9.3% above the nine months ended September 30, 2020. The change was primarily attributable to amortization on newly acquired intangible assets related to the Iotron and BioScience Labs acquisitions.

Interest Expense, Net

Interest expense, net decreased $108.6 million, or 64.9%, for the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020. The decrease was driven largely by the paydown of the Term Loan and Second Lien Notes with IPO proceeds in the fourth quarter of 2020, the redemption of the First Lien Notes in August 2021, and lower interest rates subsequent to the January 2021 Term Loan refinancing. The weighted average interest rate on our outstanding debt was 3.25% and 6.45% at September 30, 2021 and 2020, respectively.

Foreign Exchange Loss (Gain)

Foreign exchange loss was $1.4 million for the nine months ended September 30, 2021 as compared to a gain of $5.4 million in the nine months ended September 30, 2020. The foreign exchange loss (gain) in our Consolidated Statements of Operations and Comprehensive Income (Loss) relates primarily to U.S. dollar denominated intercompany indebtedness with certain of our European and Canadian subsidiaries.

Other Income, Net

Other income, net was $7.3 million for the nine months ended September 30, 2021 compared to $4.4 million for the nine months ended September 30, 2020. The fluctuation was driven by a $1.0 million gain in the fair value of the embedded

derivatives in Nordion’s contracts. We recorded an unrealized gain on embedded derivatives of $0.4 million for the nine months ended September 30, 2021 compared to a $0.6 million loss for the nine months ended September 30, 2020. In addition, we recorded $1.2 million of other income related to the gain on our purchase of the 15% mandatorily redeemable noncontrolling interest of Nelson Labs Fairfield in the second quarter of 2021 as compared to the amount previously accrued.

Provision (Benefit) for Income Taxes

Provision for income tax increased $45.5 million to a net provision of $35.9 million for the nine months ended September 30, 2021 as compared to a $9.7 million benefit in the nine months ended September 30, 2020. The change was principally attributable to pre-tax income of $117.0 million in the nine months ended September 30, 2021 compared to a pretax loss of $3.8 million for the nine months ended September 30, 2020.

Provision for income taxes for the nine months ended September 30, 2021 differed from the statutory rate primarily due to the impact of the foreign rate differential, GILTI, a net increase in the interest expense valuation allowance, and a discrete item pertaining to an income tax rate change in the United Kingdom. This was partially offset by an additional discrete item in the first quarter of 2021, which reversed the valuation allowance on deferred tax assets related to certain asset retirement obligations. Provision for income taxes for the nine months ended September 30, 2020 differed from the statutory rate primarily due to GILTI, the foreign rate differential, and changes in items that are not expected to have a future tax impact.

Net Income, Adjusted Net Income and Adjusted EBITDA

Net income for the nine months ended September 30, 2021 was $81.1 million, as compared to net income of $5.9 million for the nine months ended September 30, 2020. Adjusted Net Income was $181.9 million for the nine months ended September 30, 2021, as compared to $77.1 million for the nine months ended September 30, 2020, due to the factors described above. Adjusted EBITDA was $356.6 million for the nine months ended September 30, 2021, as compared to $306.8 million for the nine months ended September 30, 2020, due to the factors described above. Please see “Non-GAAP Financial Measures” below for a reconciliation of Adjusted Net Income and Adjusted EBITDA to their most directly comparable financial measure calculated and presented in accordance with GAAP.

NON-GAAP FINANCIAL MEASURES

To supplement our consolidated financial statements presented in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”), we consider Adjusted Net Income and Adjusted EBITDA, financial measures that are not based on any standardized methodology prescribed by GAAP.

We define Adjusted Net Income as net income (loss) before amortization and certain other adjustments that we do not consider in our evaluation of our ongoing operating performance from period to period as discussed further below. We define Adjusted EBITDA as Adjusted Net Income before interest expense, depreciation (including depreciation of Co-60 used in our operations) and income tax provision applicable to Adjusted Net Income.

We use Adjusted Net Income and Adjusted EBITDA, non-GAAP financial measures, as the principal measures of our operating performance. Management believes Adjusted Net Income and Adjusted EBITDA are useful because they allow management to more effectively evaluate our operating performance and compare the results of our operations from period to period without the impact of certain non-cash items and non-routine items that we do not expect to continue at the same level in the future and other items that are not core to our operations. We believe that these measures are useful to our investors because they provide a more complete understanding of the factors and trends affecting our business than could be obtained absent this disclosure. In addition, we believe Adjusted Net Income and Adjusted EBITDA will assist investors in making comparisons to our historical operating results and analyzing the underlying performance of our operations for the periods presented. Our management also uses Adjusted Net Income and Adjusted EBITDA in their financial analysis and operational decision-making, and Adjusted EBITDA serves as the basis for the metric we utilize to determine attainment of our primary annual incentive program. Adjusted Net Income and Adjusted EBITDA may be calculated differently from, and therefore may not be comparable to, a similarly titled measure used by other companies.

Adjusted Net Income and Adjusted EBITDA should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. There are a number of limitations related to the use of Adjusted Net Income and Adjusted EBITDA rather than net income, the nearest GAAP equivalent. For example, Adjusted Net Income and Adjusted EBITDA exclude:

•certain recurring non-cash charges such as depreciation of fixed assets, although these assets may have to be replaced in the future, as well as amortization of acquired intangible assets and asset retirement obligations;

•costs of acquiring and integrating businesses, which will continue to be a part of our growth strategy;

•non-cash gains or losses from fluctuations in foreign currency exchange rates, primarily related to remeasurement of intercompany loans denominated in currencies other than subsidiaries’ functional currencies, and the mark-to-fair value of embedded derivatives relating to certain customer and supply contracts at Nordion;

•impairment charges on long-lived assets and intangible assets;

•expenses and charges related to the litigation and other activities associated with our EO sterilization facilities in Willowbrook, Illinois, Atlanta, Georgia and Santa Teresa, New Mexico, even though that litigation remains ongoing;

•in the case of Adjusted EBITDA, interest expense or the cash requirements necessary to service interest or principal payments on our indebtedness; and

•share-based compensation expense, which has been, and will continue to be for the foreseeable future, a significant recurring expense and an important part of our compensation strategy.

In evaluating Adjusted Net Income and Adjusted EBITDA, you should be aware that in the future, we will incur expenses similar to the adjustments in the table below. Our presentations of Adjusted Net Income and Adjusted EBITDA should not be construed as suggesting that our future results will be unaffected by these expenses or any unusual or non-recurring items. When evaluating our performance, you should consider Adjusted Net Income and Adjusted EBITDA alongside other financial performance measures, including our net income and other GAAP measures.

The following table presents a reconciliation of net income, the most directly comparable financial measure calculated and presented in accordance with GAAP to Adjusted Net Income and Adjusted EBITDA, for each of the periods indicated:

SEGMENT RESULTS OF OPERATIONS

We have three reportable segments: Sterigenics, Nordion and Nelson Labs. Our chief operating decision maker evaluates performance and allocates resources within our business based on Segment Income, which excludes certain items which are included in income (loss) before tax as determined in our Consolidated Statements of Operations and Comprehensive Income (Loss). The accounting policies for our reportable segments are the same as those for the consolidated Company.

Our Segments

Sterigenics

Nordion

As a result of the time required to meet regulatory and logistics requirements for delivery of radioactive products, combined with accommodations made to our customers to minimize disruptions to their operations during the installation of Co-60, Nordion sales patterns can often vary significantly from one quarter to the next. However, timing-related impacts on our sales performance tend to be resolved within several quarters, resulting in more consistent performance over longer periods of time. In addition, sales of production irradiators occur infrequently and tend to be for larger amounts.

Results for our Nordion segment are also impacted by Co-60 supplier mix, harvest schedules and product and service mix.

Nelson Labs

Nelson Labs provides outsourced microbiological and analytical chemistry testing and advisory services for the medical device and pharmaceutical industries.

For more information regarding our reportable segments please refer to Note 18, “Segment Information” to our consolidated financial statements.

Segment Results for the Three Months Ended September 30, 2021 and 2020

The following tables compare segment net revenue and segment income for the three months ended September 30, 2021 to the three months ended September 30, 2020:

Nordion	56.8		%	50.6		%
Nelson Labs	40.3		%	44.0		%

Net Revenues by Segment

Sterigenics net revenues were $145.3 million for the three months ended September 30, 2021, an increase of $19.0 million, or 15.1%, as compared to the three months ended September 30, 2020. The increase is attributable to an 8.5% growth in organic sales volume, a 3.8% favorable impact from pricing and a 1.7% increase in revenues attributable to an additional month of operations from Iotron, which was acquired on July 31, 2020. Revenue growth was also driven by a 1.1% favorable impact from changes in foreign currency exchange rates.

Nordion net revenues were $28.8 million for the three months ended September 30, 2021, an increase of $8.5 million, or 41.9%, as compared to the three months ended September 30, 2020. The increase reflects a 30.6% impact from higher volumes, a 6.3% impact from favorable pricing, and a 5.0% effect of the strengthening of the Canadian dollar compared to the U.S. dollar for the three months ended September 30, 2021 as compared to the three months ended September 30, 2020.

Nelson Labs net revenues were $52.1 million for the three months ended September 30, 2021, a decrease of $1.4 million, or 2.6%, as compared to the three months ended September 30, 2020. The decrease was principally driven by an 8.6% decline in personal protective equipment testing. Partially offsetting this decline was a 5.3% revenue contribution from the acquisition of BioScience Labs.

Sterigenics segment income was $79.3 million for the three months ended September 30, 2021, an increase of $12.7 million, or 19.0%, as compared to the three months ended September 30, 2020. The increase in segment income was primarily a result of volume growth and favorable pricing as well as the contribution from the Iotron acquisition.

Nordion segment income was $16.3 million for the three months ended September 30, 2021, an increase of $6.1 million, or 59.2%, as compared to the three months ended September 30, 2020. The increase in segment income was primarily due to the increase in sales volumes of industrial use Co-60 coupled with the favorable impact of pricing and changes in foreign currency exchange rates.

Nelson Labs segment income was $21.0 million for the three months ended September 30, 2021, a decrease of $2.5 million, or 10.8%, as compared to the three months ended September 30, 2020. The decrease was primarily driven by the reduced demand for testing of personal protective equipment, offset by incremental segment income from the acquisition of BioScience Labs.

Segment Results for the Nine Months Ended September 30, 2021 and 2020

The following tables compare segment net revenue and segment income for the nine months ended September 30, 2021 to the nine months ended September 30, 2020:

Net Revenues by Segment

Sterigenics net revenues were $421.6 million for the nine months ended September 30, 2021, an increase of $57.7 million, or 15.9%, as compared to the nine months ended September 30, 2020. The increase reflects volume growth of 6.4% coupled with a 4.0% increase attributable to the Iotron acquisition. In addition, Sterigenics revenue growth benefited from a 3.7% favorable pricing impact and a 1.8% favorable impact from changes in foreign currency exchanges rates.

Nordion net revenues were $103.8 million for the nine months ended September 30, 2021, an increase of $17.8 million, or 20.7%, as compared to the three months ended September 30, 2020. The increase was attributable to a 7.0% growth in organic sales volume, a 7.0% effect from the strengthening of the Canadian dollar compared to the U.S. dollar for the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020, and a 6.7% impact from favorable pricing.

Nelson Labs net revenues were $164.8 million for the nine months ended September 30, 2021, an increase of $13.4 million, or 8.9%, as compared to the nine months ended September 30, 2020. Net revenue growth was driven by a 5.2% revenue contribution from the acquisition of BioScience Labs, favorable impacts from pricing of 3.4% and a 1.3% benefit from changes in foreign currency exchange rates. Offsetting these growth factors was a 1.6% decline in revenue related to the testing of personal protective equipment.

Segment Income

Sterigenics segment income was $227.4 million for the nine months ended September 30, 2021, an increase of $34.6 million, or 17.9%, as compared to the nine months ended September 30, 2020. The increase in segment income was primarily a result of volume growth coupled with the contributions of the Iotron acquisition and favorable pricing, as referenced above. This was partially offset by incremental overhead associated with being a public company.

Nordion segment income was $61.3 million for the nine months ended September 30, 2021, an increase of $10.6 million, or 20.9%, as compared to the nine months ended September 30, 2020. The increase in segment income stemmed from a balanced impact of organic sales volume, favorable customer pricing and a favorable effect of changes in foreign currency exchange rates. This was partially offset by incremental overhead associated with being a public company.

Nelson Labs segment income was $67.9 million for the nine months ended September 30, 2021, an increase of $4.6 million, or 7.3%, as compared to the nine months ended September 30, 2020, primarily attributed to the incremental contribution of

BioScience Labs and the benefit of favorable pricing. This increase was partially offset by declines in the testing of personal protective equipment and incremental overhead associated with being a public company.

LIQUIDITY AND CAPITAL RESOURCES

The primary sources of liquidity for our business are cash flows from operations and borrowings under our credit facilities. We expect that our primary liquidity requirements will be to service our debt, to invest in fixed assets to build and/or expand existing facilities, to fund selective business acquisitions, make capital expenditures and for other general corporate purposes.

As of September 30, 2021, we had $114.9 million of cash and cash equivalents. This is an increase of $12.5 million from the balance at December 31, 2020. Our foreign subsidiaries held cash of approximately $102.2 million at September 30, 2021 and $88.8 million at December 31, 2020. No material restrictions exist to accessing cash held by our foreign subsidiaries notwithstanding any potential tax consequences.

Our capital expenditure program is a component of our long-term strategy. This program includes, among other things, investments in new and existing facilities, business expansion projects, Co-60 used by Sterigenics at its gamma irradiation facilities, cobalt development projects and information technology enhancements. During the nine months ended September 30, 2021, our capital expenditures amounted to $60.9 million, compared to $33.6 million for the nine months ended September 30, 2020.

We expect that cash on hand, operating cash flows and amounts available under our credit facilities will provide sufficient working capital to operate our business, make expected capital expenditures, meet litigation costs and meet foreseeable liquidity requirements, including debt service on our long-term debt, for at least the next twelve months. Cash provided by operations in excess of amounts needed may be used to fund potential acquisitions, to repay outstanding debt, or for other general corporate purposes. As of September 30, 2021, there were no outstanding borrowings on the Revolving Credit Facility. Our ability to meet future working capital, capital expenditures and debt service requirements will depend on our future financial performance, which will be affected by a range of macroeconomic, competitive and business factors, including interest rate changes and changes in our industry, many of which are outside of our control. As of September 30, 2021, our interest rate caps limit our cash flow exposure related to LIBOR for approximately 85% of our variable rate borrowings to the facility LIBOR floor of 0.5%. Refer to Note 17, “Financial Instruments and Financial Risk” under the heading “Derivative Instruments” for additional information regarding the interest rate caps used to manage economic risks associated with our variable rate borrowings.

Cash Flow Information

Nine Months Ended September 30, 2021 compared to the Nine Months Ended September 30, 2020


(thousands of U.S. dollars)	2021		2020

Net Cash Provided by (Used in):
Operating activities	$	215,194	$	98,740
Investing activities	(87,570)		(139,920)
Financing activities	(115,504)		83,961
Effect of foreign currency exchange rate changes on cash and cash equivalents	345		2,639
Net increase in cash and cash equivalents, including restricted cash, during the period	$	12,465	$	45,420

Operating activities

Cash flows provided by operating activities increased $116.5 million to net cash provided of $215.2 million in the nine months ended September 30, 2021 compared to $98.7 million for the nine months ended September 30, 2020. Higher cash flows from operating activities in the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020 were driven by a decrease in cash paid for interest of $110.2 million and an increase in operating income of $36.7 million, offset by an increase in cash paid for income taxes of $22.3 million.

Investing activities

Cash used in investing activities decreased $52.4 million to net cash used of $87.6 million in the nine months ended September 30, 2021 compared to $139.9 million for the nine months ended September 30, 2020. The change was attributable to

a decrease of $80.3 million in cash paid for acquisitions, offset by an increase in cash paid for capital expenditures of $27.3 million. During the nine months ended September 30, 2021 we acquired BioScience Labs for a net purchase price of approximately $13.5 million and we completed the acquisition of the remaining 15% ownership of Nelson Labs Fairfield for $12.4 million. During the nine months ended September 30, 2020 we acquired Iotron for a net purchase price of $106.3 million.

Financing activities

For the nine months ended September 30, 2021, net cash used in financing activities was $115.5 million compared to net cash provided by financing activities of $84.0 million for the nine months ended September 30, 2020. For the nine months ended September 30, 2021, the principal uses of cash in financing activities were $100.0 million for the full redemption of the First Lien Notes, $8.4 million for the acquisition of the noncontrolling interests in our China subsidiaries and $6.7 million of debt issuance costs and prepayment premium incurred in connection with our refinancing of the Senior Secured Credit Facilities and the early redemption of the First Lien Notes, respectively. For the nine months ended September 30, 2020 cash provided by financing activities included a $50.0 million borrowing on our revolving credit facility in March 2020 in response to uncertainty surrounding the onset of the COVID-19 pandemic and the July 2020 issuance of the First Lien Notes to fund the acquisition of Iotron. Offsetting these sources of cash was $61.0 million in repayments on debt, including repayment of the $50.0 million borrowing on our revolving credit facility, and $3.9 million of cash used for the payment debt issuance costs.

Debt Facilities

Senior Secured Credit Facilities

On January 20, 2021, we closed on an amendment repricing our Term Loan. The interest rate spread over the London Interbank Offered Rate (“LIBOR”) on the facility was reduced from 450 basis points to 275 basis points, and the facility’s LIBOR floor was reduced from 100 basis points to 50 basis points. The changes result in an effective reduction in current interest rates of 2.25%. As a result of the repricing, we expect cash interest savings of approximately $40.0 million per year based on the outstanding principal balance as of September 30, 2021. In connection with this amendment, we wrote off $11.3 million of unamortized debt issuance and discount costs and incurred an additional $2.9 million of expense related to debt issuance costs attributable to the refinancing. These costs were recorded to “Loss on extinguishment of debt” in our Consolidated Statements of Operations and Comprehensive Income (Loss).

On March 26, 2021, we amended the Revolving Credit Facility, to (i) decrease the Applicable Rate (as defined in the Credit Agreement) related to any Revolving Loans (as defined in the Credit Agreement) from a rate per annum that ranged from an alternative base rate (“ABR”) plus 2.50% to ABR plus 3.00% depending on SHH’s Senior Secured First Lien Net Leverage Ratio to ABR plus 1.75%; and in the case of Eurodollar Loans (as defined in the Credit Agreement) from a rate per annum which ranged from the Adjusted LIBOR plus 3.50% to the Adjusted LIBOR plus 4.00% depending on SHH’s Senior Secured First Lien Net Leverage Ratio (as defined in the Credit Agreement), to the Adjusted LIBOR (as defined in the Credit Agreement) plus 2.75% and (ii) extend the maturity date of the Revolving Facility from December 13, 2024 to June 13, 2026. The other material terms of the Credit Agreement are unchanged and the amendment does not change the capacity of our Revolving Credit Facility, which is $347.5 million. No unamortized debt issuance costs associated with the Revolving Credit Facility were written off and direct fees and costs incurred in connection with the amendment were immaterial.

First Lien Notes

2020 Debt Repayments

On November 24, 2020, we closed our IPO, in which we sold 53,590,000 shares of our common stock at a price of $23.00 per share, which included the full exercise by the underwriters of their option to purchase up to an additional 6,990,000 shares of common stock. We raised approximately $1.2 billion in net proceeds after deducting underwriters’ discounts and commissions. We used the net proceeds received by us from the IPO to (i) redeem $770.0 million in aggregate principal amount of the Second Lien Senior Secured Notes with an original maturity date of December 13, 2027 (the “Second Lien Notes”), plus accrued and unpaid interest thereon and $15.4 million of redemption premium, (ii) repurchase 1,568,445 shares of our common stock from certain of our executive officers at a purchase price per share equal to the IPO price per share of our common stock less an amount equal to the underwriting discounts and commissions payable thereon and (iii) repay $341.0 million of the outstanding indebtedness under the Term Loan, plus accrued and unpaid interest thereon. In connection with the debt repayments, we wrote off $28.9 million of debt issuance and discount costs and recognized $15.4 million in premiums paid for the early extinguishment of the Second Lien Notes. We recognized these costs within “Loss on extinguishment of debt” in our Consolidated Statements of Operations and Comprehensive Income (Loss) in the fourth quarter of 2020.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The preparation of consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make judgments, estimates and assumptions at a specific point in time and in certain circumstances that affect amounts reported in the accompanying consolidated financial statements. In preparing these consolidated financial statements, management has made its best estimates and judgments of certain amounts, giving due consideration to materiality. The application of accounting policies involves the exercise of judgment and use of assumptions as to future uncertainties and, as a result, actual results could differ from these estimates.

A comprehensive discussion of the Company’s critical accounting policies and management estimates made in connection with the preparation of the financial statements is included in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2020. There have been no significant changes in critical accounting policies, management estimates or accounting policies since the year ended December 31, 2020.

Zoetermeer, Holland Criminal Proceedings and Criminal Financial Investigation

In early 2010, the Dutch Public Prosecution Service started criminal proceedings against DEROSS Holding B.V. (“DEROSS B.V.”), formerly known as Sterigenics Holland B.V., in relation to certain EO emissions and alleged environmental permit violations in the period from 2004 to 2009 at its Zoetermeer processing facility. On the basis of the final indictment issued in April 2017, assuming a rarely applied increasing mechanism is not applied in this case, fines in the amount of €0.8 million (US$0.9 million) may be imposed.

In November 2010, the Public Prosecution Service also started a criminal financial investigation against DEROSS B.V. to determine whether it obtained illegal advantages by committing the alleged criminal offenses noted above. Any illegally obtained advantage could then be recovered from DEROSS B.V. in subsequent confiscation proceedings. According to the October 2013 report of this criminal financial investigation, the Public Prosecution Service estimates the illegally obtained advantage by DEROSS B.V. to be in the amount of €0.6 million (US$0.7 million).

In January 2018, the trial in first instance took place in the criminal case against DEROSS B.V., and in February 2018, the court discharged DEROSS B.V. from further prosecution on one of the two counts asserted and acquitted DEROSS B.V. on the other count. In March 2018, the public prosecutor filed an appeal against the favorable judgment in first instance for DEROSS B.V., as well as the favorable judgments in first instance for the two individuals overseeing environmental compliance during the time period of the alleged claims and the municipality of Zoetermeer. The appeal procedure is pending.

DEROSS B.V. has agreed to defend and indemnify the two individuals overseeing environmental compliance during the time period of the alleged claims by the Public Prosecutor. Assuming a rarely applied increasing mechanism is not applied in this case, the possible monetary penalties relating to the individuals currently are estimated at a maximum of €0.2 million (US$0.2 million).

In 2011, former shareholders established an escrow account to satisfy indemnity claims for losses resulting from governmental claims related to this matter, including those relating to environmental law violations, financial advantage claims, as well as criminal and civil fines and penalties. The balance of the special escrow at September 30, 2021 was approximately US$1.9 million and the cash collateral held by ABN Amro to provide security for the claims was approximately €2.4 million (US$2.8 million) as of September 30, 2021. These amounts are available to satisfy claims relating to the ongoing matter through its anticipated resolution. At this time, we expect that the appeal of this matter will likely take several years to resolve, barring unforeseen delays. However, we believe the indemnification receivable continues to be recoverable and plan to ensure escrow funds remain in place to cover outcomes of an appeal.

It is possible that individuals living in the vicinity of our former Zoetermeer facility may file civil claims at some time in the future. While we have received letters from a small number of individuals claiming to live or work in the vicinity of the Zoetermeer facility, no civil claims have been filed against DEROSS B.V. or us. We have not provided for a contingency reserve in connection with any civil claims as we are unable to determine the likelihood of an unfavorable outcome and no reasonable estimate of a loss or range of losses, if any, can be made.

Item 1A. Risk Factors.

There have been no material changes to the risk factors previously disclosed in our 2020 Form 10-K. Refer to Part I, Item 1A of our 2020 Form 10-K for a detailed discussion of risk factors affecting us.
