CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward looking statements are often characterized by the use of the words such as “believes,” “estimates,” “expects,” “projects,” “may,” “intends,” “plans” or “anticipates,” or by discussions of strategy, plans or intentions. Such forward-looking statements involve known and unknown risks, uncertainties and other important factors that could cause our actual results, performance or achievements, or industry results, to differ materially from historical results or any future results, performance or achievements expressed, suggested or implied by such forward-looking statements. Such risks and uncertainties include, but are not limited to:

•disruption in the availability of, or increases in the price of, ethylene oxide (“EO”), Cobalt-60 (“Co-60”) or our other direct materials, services and supplies, including as a result of current geopolitical instability arising from U.S., Canadian and European Union relations with Russia and related sanctions;

•adverse changes in industry trends;

•changes in environmental, health and safety regulations or preferences;

•health and safety risks associated with the use, storage, transportation and disposal of potentially hazardous materials such as EO and Co-60;

•liability claims relating to health risks associated with the use of EO;

•current and future legal proceedings;

•competition we face;

•market changes, including inflationary trends, that impact our long-term supply contracts with variable price clauses and increase our cost of revenues;

•allegations of our failure to properly perform services and potential product liability claims, recalls, penalties and reputational harm;

•compliance with the extensive regulatory requirements to which we are subject, the related costs, and any failures to receive or maintain, or delays in receiving, required clearance or approvals;

•business continuity hazards, including supply chain disruptions and other risks associated with our operations;

•the ongoing impact of the COVID-19 pandemic;

•our ability to increase capacity at existing facilities, build new facilities in a timely and cost-effective manner and renew leases for our facilities;

•our ability to attract and retain qualified employees;

•the risks of doing business internationally, including global and regional economic and political instability and compliance with numerous laws and regulations in multiple jurisdictions;

•cyber security breaches, unauthorized data disclosures, and our dependence on information technology systems;

•any inability to pursue strategic transactions, including our ability to find suitable acquisition targets, or our failure to integrate strategic acquisitions successfully into our business;

•our ability to maintain effective internal controls over financial reporting;

•our reliance on intellectual property to maintain our competitive position and the risk of claims from third parties that we infringe or misappropriate their intellectual property rights;

•our ability to comply with rapidly evolving data privacy and security laws and regulations and any ineffective compliance efforts with such laws and regulations;

•the effects of unionization efforts and labor regulations in certain countries in which we operate;

•our ability to maintain profitability in the future;

•impairment charges on our goodwill and other intangible assets with indefinite lives, as well as other long-lived assets and intangible assets with definite lives;

•adverse changes to our tax positions in U.S. or non-U.S. jurisdictions, the interpretation and application of recent U.S. tax legislation or other changes in U.S. or non-U.S. taxation of our operations;

•our significant leverage could adversely affect our ability to raise additional capital, limit our ability to react to changes in the economy or our industry, limit our flexibility in operating our business through restrictions contained in our debt agreements and prevent us from meeting our obligations under our existing and future indebtedness; and

•uncertainty around discontinuation of LIBOR and transition to certain other interest “benchmarks.”

These statements are based on current plans, estimates and projections, and therefore you should not place undue reliance on them. Forward-looking statements speak only as of the date they are made, and we undertake no obligation to update them publicly in light of new information or future events, except as required by law. The inclusion of this forward-looking information should not be regarded as a representation by us or any other person that the future plans, estimates or expectations contemplated by us will be achieved.

Table of Contents

You should carefully consider the above factors, as well as the factors discussed elsewhere in this Quarterly Report on Form 10-Q, including under Part II, Item 1A, “Risk Factors,” as well as Part I, Item 1A, “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 10-K”). If any of these trends, risks or uncertainties actually occurs or continues, our business, financial condition or operating results could be materially adversely affected, the trading prices of our securities could decline and you could lose all or part of your investment. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by this cautionary statement.

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 represented the noncontrolling stockholders’ proportionate share of the total equity in the Company’s consolidated subsidiaries. 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. Prior to our acquisition of the noncontrolling interests in our two subsidiaries in China, we consolidated the results of operations of these subsidiaries with our results of operations and reflected the noncontrolling interest 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 Auralux Enterprises, Ltd. (“Auralux”), a joint venture to construct an E-beam facility in Alberta, Canada in connection with our acquisition of Iotron Industries Canada, Inc. (“Iotron”). We determined this to be an investment in a variable interest entity (“VIE”). The investment was not consolidated as the Company 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. During the three months ended June 30, 2022, we identified certain events and circumstances that indicated a decline in value of our investment in Auralux that was other-than-temporary. Consequently, as of June 30, 2022, we wrote down the investment in Auralux to its fair value of $0, resulting in an impairment charge of approximately $9.6 million.

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, 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, 2021.

2.Recent Accounting Standards

Adoption of Accounting Standard Updates

Effective January 1, 2022, we adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (“ASU 2016-13”): Measurement of Credit Losses on Financial Instruments, and the subsequently issued additional guidance that modified ASU 2016-13 which was originally issued by the Financial Accounting Standards Board (“FASB”) in June 2016. 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. The adoption of this standard did not have a material impact on our consolidated financial statements and disclosures.

Notes to Consolidated Financial Statements

Effective January 1, 2022, we adopted ASU 2019-12 - Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes which was issued by the FASB in December 2019. 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. The adoption of this standard did not have a material impact on our consolidated financial statements and disclosures.

ASUs Issued But Not Yet Adopted

In October 2021, the FASB issued ASU 2021-08 - Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). The amendments in ASU 2021-08 require that an acquiring entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contract with Customers (“ASC Topic 606”). At the acquisition date, an acquirer should account for the related revenue contracts in accordance with ASC Topic 606 as if it had originated the contracts. For public business entities, these amendments are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. We are currently assessing the effect that ASU 2021-08 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 $6.9 million and $8.7 million at June 30, 2022 and December 31, 2021, respectively. We recognize deferred revenue after all revenue recognition criteria are met.

4.Acquisitions

Acquisition of Regulatory Compliance Associates Inc.

On November 4, 2021, we acquired Regulatory Compliance Associates Inc. (“RCA”) for approximately $30.6 million, net of $0.6 million of cash acquired. RCA is an industry leader in providing life sciences consulting focused on quality, regulatory, and technical advisory services for the pharmaceutical, medical device and combination device industries. Headquartered in Pleasant Prairie, Wisconsin, RCA will expand and further strengthen the technical consulting and expert advisory capabilities of our Nelson Labs segment.

The purchase price of RCA 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. As of June 30, 2022, approximately $25.2 million of goodwill was recorded related to the RCA acquisition, representing the excess of the purchase price over preliminary estimated fair values of all the assets acquired and liabilities assumed. Based on our most recent estimates, we also recorded $6.4 million of finite-lived intangible assets, primarily related to customer relationships. The purchase price allocation will be finalized within a measurement period not to exceed one year from closing. We funded this acquisition using available cash. The acquisition price and the results of operations for this acquired entity are not material in relation to our consolidated financial statements.

Acquisition of Noncontrolling Interests in China Subsidiaries

On May 18, 2021, we 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. We 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 remain outstanding as of June 30, 2022 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 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 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 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 Lab's outstanding debt of $1.9 million. BioScience Labs is a provider of outsourced topical antimicrobial product testing in the pharmaceutical, medical device, and consumer products industries with one location in Bozeman, Montana. BioScience Labs is included within the Nelson Labs segment.

(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 year license period as Nordion has demonstrated over its 75 years of history.

Amounts include the impact of foreign currency translation.

Amortization expense for other intangible assets was $21.2 million ($5.4 million is included in “Cost of revenues” and $15.8 million in “Selling, general and administrative expenses”) and $41.4 million ($9.8 million is included in “Cost of revenues” and $31.6 million in “Selling, general and administrative expenses”) in the Consolidated Statements of Operations and Comprehensive Income (Loss) for the three and six months ended June 30, 2022, 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 Revolving Credit Facility and Term Loan mature on June 13, 2026 and December 13, 2026, respectively. The total borrowing capacity under the Revolving Credit Facility is $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 June 30, 2022 and December 31, 2021, total borrowings under the Term Loan were $1,763.1 million, 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 June 30, 2022 and June 30, 2021 was 3.53% and 3.25%, respectively, and 3.39% and 3.64% for the six months ended June 30, 2022 and June 30, 2021, 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 resulted in an effective reduction in current interest rates of 225 basis points. 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 remain unchanged and the amendment does not change the capacity of our Revolving Credit Facility. 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.

As of June 30, 2022 and December 31, 2021, capitalized debt issuance costs totaled $2.4 million and $2.7 million, respectively, and debt discounts totaled $15.6 million and $17.3 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.

The Senior Secured Credit Facilities contain additional covenants that, among other things, restrict, subject to certain exceptions, our ability and the ability of our restricted subsidiaries to engage in certain activities, such as incur indebtedness or permit to exist any lien on any property or asset now owned or hereafter acquired, as specified in the Senior Secured Credit Facilities. The Senior Secured Credit Facilities also contain certain customary affirmative covenants and events of default, including upon a change of control. As of June 30, 2022, we were in compliance with all the Senior Secured Credit Facilities covenants.

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.

Sotera Health Company

Notes to Consolidated Financial Statements

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 June 30, 2022, the Company had $70.1 million of letters of credit issued against the Revolving Credit Facility, resulting in total availability under the Revolving Credit Facility of $277.4 million.

Term Loan Interest Rate Risk Management

The Company utilizes interest rate derivatives to reduce the variability of cash flows in the interest payments associated with the Term Loan due to changes in LIBOR (or its successor). For additional information on the derivative instruments described above, refer to Note 17, “Financial Instruments and Financial Risk”, “Derivatives Instruments.”

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 year ended December 31, 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%.

Aggregate Maturities

Aggregate maturities of the Company’s long-term debt, excluding debt discounts, as of June 30, 2022, are as follows:


(thousands of U.S. dollars)
2022	$	—
2023	450
2024	—
2025	—
2026	1,763,100
Thereafter	—
Total	$	1,763,550

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 36.8 % and 34.6% for the three and six months ended June 30, 2022, respectively, compared to 31.0% and 29.3% for the three and six months ended June 30, 2021, respectively.

Income tax expense for the three months ended June 30, 2022 differed from the statutory rate primarily due to a net increase in the valuation allowance, the impact of the foreign rate differential, and global intangible low-tax income (“GILTI”). The increase in the valuation allowance was attributable to the limitation on the deductibility of interest expense and the impairment of the investment in Auralux. Provision for income tax expense for the three months ended June 30, 2021 was offset by a discrete item, which reversed the valuation allowance on deferred tax assets related to certain asset retirement obligations.

Table of Contents

Sotera Health Company

Notes to Consolidated Financial Statements

Income tax expense for the six months ended June 30, 2022 differed from the statutory rate primarily due to a net increase in the valuation allowance, the impact of the foreign rate differential, and GILTI. Provision for income tax expense for the six months ended June 30, 2021 was 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.

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.

Defined benefit pension plan

The interest cost, expected return on plan assets and amortization of net actuarial loss are recorded in “Other expense (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 plan for the three and six months ended June 30, 2022 and 2021 were as follows:


	Three Months Ended June 30,				Six Months Ended June 30,
(thousands of U.S. dollars)	2022		2021		2022		2021
Service cost	$	247	$	307	$	496	$	605
Interest cost	1,889		1,662		3,792		3,275
Expected return on plan assets	(3,676)		(3,665)		(7,380)		(7,222)
Amortization of net actuarial loss	—		275		—		542
Net periodic benefit	$	(1,540)	$	(1,421)	$	(3,092)	$	(2,800)

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 six months ended June 30, 2022 and 2021 were as follows:


	Three Months Ended June 30,				Six Months Ended June 30,
(thousands of U.S. dollars)	2022		2021		2022		2021
Service cost	$	4	$	7	$	8	$	14
Interest cost	65		61		130		120
Amortization of net actuarial (gain) loss	(2)		9		(4)		17
Net periodic benefit cost	$	67	$	77	$	134	$	151

We currently expect funding requirements of approximately $3.1 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 June 30, 2022, and December 31, 2021, we had letters of credit outstanding relating to the defined benefit plans totaling $46.9 million and $46.2 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.

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 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 June 30, 2022, these awards remain unvested.

We recognized $0.5 million and $0.7 million of share-based compensation expense related to the pre-IPO Class B-1 awards for the three months ended June 30, 2022 and 2021, respectively, and $1.1 million and $1.3 million for the six months ended June 30, 2022 and 2021, respectively.

A summary of the activity for the six months ended June 30, 2022 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, 2021	1,206,089	2,023,959

2021 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 $5.3 million ($2.2 million for stock options and $3.1 million for RSUs) and $2.8 million ($1.3 million for stock options and $1.5 million for RSUs) of share-based compensation expense for these awards for the three months ended June 30, 2022 and 2021, respectively. We recognized $9.2 million ($3.7 million for stock options and $5.5 million for RSUs) and $5.6 million ($2.5 million for stock options and $3.1 million for RSUs) for the six months ended June 30, 2022 and 2021, respectively, 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.

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.

Ethylene Oxide Tort Litigation

Sterigenics and other medical supply sterilization companies have been subjected to personal injury and related tort lawsuits alleging various injuries caused by low-level environmental exposure to EO emissions from sterilization facilities. Those lawsuits, as detailed further below, are individual claims, as opposed to class actions.

Sotera Health Company

Notes to Consolidated Financial Statements

Illinois

Approximately 780 plaintiffs have filed lawsuits against subsidiaries of the Company and other parties, alleging personal injuries including cancer and other diseases, or wrongful death, resulting from purported emissions and releases of EO from Sterigenics U.S., LLC’s former Willowbrook facility. Additional derivative claims are alleged on behalf of other individuals related to some of these personal injury plaintiffs. Each plaintiff seeks damages in an amount to be determined by the trier of fact. The lawsuits were consolidated for pre-trial purposes by the Cook County Circuit Court, Illinois (the “Consolidated Case”). Plaintiffs have not yet made any specific damages claims.

Fact discovery in the Consolidated Case concluded on February 1, 2022. On June 28, 2022 the Court granted summary judgment, dismissing plaintiffs’ ultrahazardous activity / strict liability claims and denying the remainder of the motions. Three of the individual cases included in the Consolidated Case have been scheduled for trials in 2022. Plaintiffs in those three cases have been granted permission to seek punitive damage awards against subsidiaries of the Company and another party. The first trial is now expected to begin on August 12, 2022. The next two individual trials are scheduled to begin in the third and fourth quarters of 2022, followed by five individual trials scheduled to occur consecutively, beginning in the first quarter of 2023. Additional trial dates are expected to be announced on September 7, 2022.

Georgia

Since August 17, 2020, approximately 300 plaintiffs have filed lawsuits against subsidiaries of the Company 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 some of 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. All but two of the personal injury lawsuits pending in Cobb County have been consolidated for pretrial purposes. The Court has entered a phased case management schedule for a “pool” of ten of the consolidated cases by which threshold general causation issues will be decided in Phase 1, followed by specific causation issues in Phase 2 as to any of the pooled cases that survive Phase 1. The Court has stayed the remainder of the consolidated personal injury cases pending in Cobb County and an immediate appeal of a discrete procedural issue is being pursued by the defendants. One personal injury case is pending in Gwinnett County and is scheduled for trial in June 2023. The remaining two personal injury cases and two property devaluation cases are in various stages of pleadings and motions practice and fact discovery.

Georgia Facility Operations Litigation

In October 2019, while Sterigenics had voluntarily suspended the facility’s operations to install emissions reduction enhancements at its Atlanta facility, 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. On March 30, 2020 Sterigenics filed suit against Cobb County, Georgia and certain of its officials for wrongfully interfering with operations of the facility. On April 1, 2020 Sterigenics won a Temporary Restraining Order prohibiting Cobb County officials from interfering with the facility’s normal operations, which relief has been extended until entry of a final judgment in the case. The parties are conducting expert discovery, which is scheduled to end in September 2022. A Modified Scheduling Order was entered on July 14, 2022, including that trial will take place no later than March 2023.

New Mexico Attorney General Litigation

On December 22, 2020, the New Mexico Attorney General filed a lawsuit in the Third Judicial District Court, Doña Ana County, New Mexico against the Company and certain subsidiaries alleging that emissions of EO from Sterigenics’ sterilization facility in Santa Teresa, New Mexico 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 seeks various forms of relief including a temporary restraining order and preliminary injunctive relief and damages. 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. On December 20,

Notes to Consolidated Financial Statements

2021 the Court entered an order identifying a protocol to monitor Sterigenics’ compliance with the Order. 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.

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 June 30, 2022, we have utilized approximately $6.0 million of the remaining $10.0 million limit. Our insurance for future alleged environmental liabilities excludes coverage for EO claims.

In addition, we are pursuing other insurance coverage for EO tort litigation. In 2021, Sterigenics U.S., LLC filed an insurance coverage lawsuit in the U.S. District Court for the Northern District of Illinois relating to two commercial general liability policies issued in the 1980s. On August 3, 2022, the Court issued a Memorandum Opinion and Order concluding that the insurer owes Sterigenics U.S., LLC and another insured party a duty to defend the Willowbrook, Illinois litigation, which may allow us to recover defense costs related to that litigation.

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

From time to time, the Company utilizes interest rate derivatives designated in hedge relationships to manage interest rate risk associated with our variable rate borrowings. These instruments are measured at fair value with changes in fair value recorded as a component of “Accumulated other comprehensive income (loss)” on our Consolidated Balance Sheets.

In May 2022, we entered into two interest rate cap agreements with a combined notional amount of $1,000.0 million for a total option premium of $4.1 million. The interest rate caps have a forward start date of July 31, 2023 and expire on July 31, 2024. We have designated these interest rate caps as cash flow hedges designed to hedge the variability of cash flows attributable to changes in the benchmark interest rate of our Term Loan. Under the current terms of the loan agreement, the benchmark interest rate index is expected to transition from LIBOR to the term Secured Overnight Financing Rate (“SOFR”) at the earlier of June 30, 2023 or the Company’s election to “early opt-in” to SOFR. Accordingly, the interest rate cap agreements hedge the variability of cash flows attributable to changes in SOFR by limiting our cash flow exposure related to the term SOFR under a portion of our variable rate borrowings to 3.5%.

In October 2021, we entered into two interest rate cap agreements with a combined notional amount of $1,000.0 million for a total option premium of $1.8 million. Both interest rate caps have a forward start date of December 31, 2022 and expire on July 31, 2023. These interest rate caps are designated as cash flow hedges and are designed to hedge the variability of cash flows attributable to changes in LIBOR (or its successor), the benchmark interest rate being hedged, by limiting our cash flow exposure related to the LIBOR base rate under a portion of our variable rate borrowings to 1.0%.

Derivatives Not Designated in Hedge Relationships

Additionally, from time to time, the Company enters into interest rate derivatives to manage economic risks associated with our variable rate borrowings that are not designated in hedge relationships. These instruments are recorded at fair value on the Consolidated Balance Sheets, with any changes in the value recorded in “Interest expense, net” in the Consolidated Statements of Operations and Comprehensive Income (Loss).

Table of Contents

Sotera Health Company

Notes to Consolidated Financial Statements

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%. In February 2021, we amended the two interest rate cap agreements referenced above to reduce the strike rate from 1% to 0.5%. 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 were 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 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 June 30, 2022 and December 31, 2021, 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 expense (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:


	June 30, 2022							December 31, 2021
(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 designated as hedging instruments:
Interest rate caps	$	2,000.0	(a)	$	19,144	$	—	$	1,000.0	$	2,322	$	—
Derivatives not designated as hedging instruments:
Interest rate caps	$	1,000.0		$	11,100	$	—	$	1,500.0	$	1,654	$	—
Embedded derivatives	190.7		(b)	1,389		2,322		144.4		496		—
Total	$	3,190.7		$	31,633	$	2,322	$	2,644.4	$	4,472	$	—

(a)$1,000.0 million and $1,000.0 million notional amount of interest rate caps designated as hedging instruments have forward start dates beginning on December 31, 2022 and July 31, 2023, respectively.

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

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

Unrealized gain on interest rate derivatives recorded in other comprehensive income (loss), net of tax	$	3,178	$	—		$	9,357	$	—

We expect to reclassify approximately $12.5 million of after-tax net gains on derivative instruments from accumulated other comprehensive income (loss) to income during the next 12 months associated with our cash flow hedges.

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 June 30, 2022 and December 31, 2021, accounts receivable was net of an allowance for uncollectible accounts of $1.8 million and $1.3 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.

Our credit team evaluates and regularly monitors changes in the credit risk of our customers. We routinely assess the collectability of accounts receivable and maintain an adequate allowance for uncollectible accounts to address potential credit losses. The process includes a review of customer financial information and credit ratings, current market conditions as well as the expected future economic conditions that may impact the collection of trade receivables. We regularly review our customers' past due amounts through an analysis of aged accounts receivables, specific customer past due aging amounts, and the history of trade receivables written off. Upon concluding that a receivable balance is not collectible, the balance is written off against the allowance for uncollectible accounts.

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:

Embedded derivatives are valued using internally developed models that rely on observable market inputs including foreign currency forward curves.

(c)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 upon quoted prices for the Term Loan due 2026 in inactive markets as provided by an independent fixed income security pricing service. Fair value approximates carrying value for “Other long-term debt.”

(d)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. We have determined our reportable segments based upon an assessment of organizational structure, service types, and internally prepared financial statements. Our chief operating decision maker evaluates performance and allocates resources

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 six months ended June 30, 2022, respectively, we recorded net revenues of $266.6 million and $503.4 million, net income of $30.4 million and $61.1 million, Adjusted Net Income of $75.8 million and $136.1 million, and Adjusted EBITDA of $136.1 million and $251.5 million. For the definition of Adjusted Net Income and Adjusted EBITDA and the reconciliation of these non-GAAP measures from net income, 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 impacted our operating results for the three and six months ended June 30, 2022 and may continue to affect our performance and financial condition in future periods.

•Business and market conditions. During the three and six months ended June 30, 2022, Sterigenics and Nordion continued to benefit from a sustained demand for sterilization services. Although the decline in pandemic-related testing stabilized in the second quarter, the competitive labor market, broad inflationary impacts, supply chain constraints and regulatory update delays remained an ongoing challenge for Nelson Labs. As discussed in more detail in our most recent Form 10-K, a portion of our supply of Co-60 is generated by Russian nuclear reactors. We continue to monitor the potential for disruption in the supply of Co-60 from Russian nuclear reactors; to date there has been no material impact on our supply or revenue.

•Investment initiatives. We remain focused on our investments in capacity expansions and facility improvements as well as our efforts to strengthen our Co-60 supply chain. For the six months ended June 30, 2022, we increased capital expenditures by $26.9 million compared to the six months ended June 30, 2021.

•Disciplined and strategic M&A activity. We remain committed to our highly disciplined acquisition strategy and continue to seek suitable acquisition targets in 2022. On November 4, 2021, we acquired Regulatory Compliance Associates Inc. (“RCA”) headquartered in Pleasant Prairie, Wisconsin. RCA is an industry leader in providing life sciences consulting focused on quality, regulatory, and technical consulting for the pharmaceutical, medical device and combination device industries. RCA expands and strengthens the technical consulting and expert advisory capabilities of Nelson Labs. On March 8, 2021, we acquired BioScience Laboratories, LLC (“BioScience Labs”) based in Bozeman, Montana, bringing expertise in antimicrobial and virology testing to our Nelson Labs segment.

•Litigation costs. 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 $17.7 million and $35.7 million for the three and six months ended June 30, 2022, respectively. Insurance coverage has been available for some of our costs in this ethylene oxide (“EO”) tort litigation in the past and as of June 30, 2022 we have approximately $4.0 million of such coverage remaining. Our insurance for future alleged environmental liabilities excludes coverage for EO claims. See Note 16, “Commitments and Contingencies”. In addition, we are pursuing other insurance coverage for EO tort litigation. In 2021, Sterigenics U.S., LLC filed an insurance coverage lawsuit in the U.S. District Court for the Northern District of Illinois relating to two commercial general liability policies issued in the 1980s. On August 3, 2022, the Court issued a Memorandum Opinion and Order concluding that the insurance company owes Sterigenics U.S., LLC and another party a duty to defend the Willowbrook, Illinois litigation, which may allow us to recover defense costs related to that litigation.

Total Net Revenues

The following table compares our revenues by type for the three months ended June 30, 2022 to the three months ended June 30, 2021.


(thousands of U.S. dollars)
Net revenues for the three months ended June 30,	2022		2021		$ Change		% Change

Service	$	221,529	$	208,710	$	12,819	6.1	%
Product	45,110		43,207		1,903		4.4	%
Total net revenues	$	266,639	$	251,917	$	14,722	5.8	%

Net revenues were $266.6 million in the three months ended June 30, 2022, an increase of $14.7 million, or 5.8%, as compared with the three months ended June 30, 2021. Excluding the impact of foreign currency exchange rates, net revenues in the three months ended June 30, 2022 increased approximately 8.5% compared with the three months ended June 30, 2021.

Service revenues

Service revenues increased $12.8 million, or 6.1%, to $221.5 million in the three months ended June 30, 2022 as compared to $208.7 million in the three months ended June 30, 2021. The increase in net service revenue was driven by favorable pricing of $8.9 million and $3.1 million in the Sterigenics and Nelson Labs segments, respectively, and sales volume growth of $7.3 million in the Sterigenics segment. The RCA acquisition also contributed $3.3 million to service revenue growth. Partially offsetting these factors was an overall decline of $2.9 million in pandemic-related testing revenue in the Nelson Labs segment.

Service revenue growth was also offset by a $5.3 million unfavorable impact from changes in foreign currency exchange rates across all segments.

Product revenues

Product revenues increased $1.9 million, or 4.4%, to $45.1 million in the three months ended June 30, 2022 as compared to $43.2 million in the three months ended June 30, 2021. The increase in product revenues was attributable to favorable pricing of $3.0 million partially offset by a $1.3 million unfavorable impact from changes in foreign currency exchange rates.

Total Cost of Revenues

The following table compares our cost of revenues by type for the three months ended June 30, 2022 to the three months ended June 30, 2021.


(thousands of U.S. dollars)
Cost of revenues for the three months ended June 30,	2022		2021		$ Change		% Change

Service	$	98,407	$	91,391	$	7,016	7.7	%
Product	17,836		16,765		1,071		6.4	%
Total cost of revenues	$	116,243	$	108,156	$	8,087	7.5	%

Total cost of revenues accounted for approximately 43.6% and 42.9% of our consolidated net revenues for the three months ended June 30, 2022 and 2020, respectively.

Cost of service revenues

Cost of service revenues increased $7.0 million, or 7.7%, for the three months ended June 30, 2022 as compared to the three months ended June 30, 2021. The increase was attributable to $6.5 million of increased costs arising from inflationary pressures, mainly on labor and the cost of energy. Cost of sales was also impacted by an incremental contribution of $2.3 million from the RCA acquisition in the Nelson Labs segment. Partially offsetting the total increase was a $2.7 million impact from changes in foreign currency exchange rates.

Cost of product revenues

Cost of product revenues increased $1.1 million, or 6.4%, for the three months ended June 30, 2022 as compared to the three months ended June 30, 2021. The increase reflects incremental costs due to product mix offset by changes in foreign currency exchange rates.

Operating Expenses

The following table compares our operating expenses for the three months ended June 30, 2022 to the three months ended June 30, 2021:


(thousands of U.S. dollars)
Operating expenses for the three months ended June 30,	2022		2021		$ Change		% Change

Selling, general and administrative expenses	$	63,132	$	49,828	$	13,304	26.7	%
Amortization of intangible assets	15,769		15,661		108		0.7	%

Total operating expenses	$	78,901	$	65,489	$	13,412	20.5	%

Operating expenses accounted for approximately 29.6% and 26.0% of our consolidated net revenues for the three months ended June 30, 2022 and 2021, respectively.

SG&A

SG&A increased $13.3 million, or 26.7%, for the three months ended June 30, 2022 as compared to the three months ended June 30, 2021. The increase was driven primarily by the following factors:

•$7.0 million increase in litigation and other professional services expense associated with EO sterilization facilities;

•$2.3 million increase in share-based compensation expense related to our 2020 Omnibus Incentive Plan; and

•$2.6 million increase in selling and administrative personnel and post-COVID-19 travel costs in support of our general business growth.

Amortization of intangible assets

Amortization of intangible assets was $15.8 million for the three months ended June 30, 2022, or 0.7% above the three months ended June 30, 2021. The increase was due mainly to changes in foreign currency exchange rates.

Interest Expense, Net

Interest expense, net decreased $5.1 million, or 26.7%, for the three months ended June 30, 2022 as compared to the three months ended June 30, 2021. The decrease was primarily driven by a $4.4 million reduction to interest expense attributable to the favorable change in fair value and quarterly settlement of interest rate derivatives not designated as hedging instruments. The decrease was also driven by a decline in interest expense on outstanding borrowings of $0.9 million, due largely to a lower average outstanding debt balance for the three months ended June 30, 2022 compared to the three months ended June 30, 2021. The weighted average interest rate on our outstanding debt was 3.81% and 3.45% at June 30, 2022 and 2021, respectively.

Impairment of Investment in Unconsolidated Affiliate

During the three months ended June 30, 2022, we recorded an impairment charge of $9.6 million related to a joint venture investment in Auralux Enterprises Ltd. (“Auralux”) which was acquired as part of the 2020 Iotron acquisition. Due to a shift in business strategy, the joint venture will not proceed, and our joint venture partner will continue to rely on our other existing operating facilities. Based on these facts and circumstances, we concluded that the investment was impaired as of June 30, 2022.

Foreign Exchange Loss (Gain)

Foreign exchange gain was $0.8 million for the three months ended June 30, 2022 as compared to a loss of $0.1 million in the three months ended June 30, 2021. The change in foreign exchange loss (gain) in our Consolidated Statements of Operations and Comprehensive Income (Loss) mainly relates to short-term losses (offset by short-term gains) on sales denominated in currencies other than the functional currency of our operating entities. As described in Note 17, “Financial Instruments and Financial Risk” we enter into monthly U.S. dollar-denominated foreign currency forward contracts to manage foreign currency exchange rate risk of our intercompany loans in certain of our international subsidiaries.

Other Expense (Income), Net

Other expense (income), net was $0.5 million for the three months ended June 30, 2022 compared to $(2.8) million for the three months ended June 30, 2021. The fluctuation was mainly driven by unfavorable changes in the fair value of Nordion’s embedded derivatives in the three months ended June 30, 2022.

Provision for Income Taxes

Provision for income tax decreased $1.5 million to a net provision of $17.7 million for the three months ended June 30, 2022 as compared to $19.2 million in the three months ended June 30, 2021. The change was primarily attributable to lower pre-tax income for the three months ended June 30, 2022 compared to the three months ended June 30, 2021.

Provision for income taxes for the three months ended June 30, 2022 and the three months ended June 30, 2022 differed from the statutory rate primarily due to an increase in the valuation allowance, the impact of the foreign rate differential, and tax on Global Intangible Low Taxed Income (“GILTI”). The increase in the valuation allowance was attributable to the limitation on the deductibility of interest expense and the impairment of the investment in Auralux. Provision for income taxes for the three months ended June 30, 2021 was partially offset by a discrete item, which reversed the valuation allowance on deferred tax assets related to certain asset retirement obligations.

Net Income, Adjusted Net Income and Adjusted EBITDA

Net income for the three months ended June 30, 2022 was $30.4 million, as compared to net income of $42.6 million for the three months ended June 30, 2021. Adjusted Net Income was $75.8 million for the three months ended June 30, 2022, as compared to $71.7 million for the three months ended June 30, 2021, due to the factors described above. Adjusted EBITDA was $136.1 million for the three months ended June 30, 2022, as compared to $134.6 million for the three months ended June 30, 2021, 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.

Net revenues were $503.4 million in the six months ended June 30, 2022, an increase of $39.3 million, or 8.5%, as compared with the six months ended June 30, 2021. Excluding the impact of foreign currency exchange rates, net revenues in the six months ended June 30, 2022 increased approximately 10.4% compared with the six months ended June 30, 2021.

Service revenues

Service revenues increased $30.3 million, or 7.6%, to $427.7 million in the six months ended June 30, 2022 as compared to $397.4 million in the six months ended June 30, 2021. The increase in net service revenue was driven by sales volume growth of $20.2 million in the Sterigenics segment and $15.9 million and $5.4 million from favorable pricing in the Sterigenics and Nelson Labs segments, respectively. The BioScience Labs and RCA acquisitions also contributed $8.0 million to service revenue growth. Partially offsetting these factors was an overall decline of $8.8 million in pandemic-related testing revenue as well as a decrease in volumes in other testing categories in the Nelson Labs segment. Service revenue growth was offset by a $7.7 million unfavorable impact from changes in foreign currency exchange rates across all segments.

Product revenues

Product revenues increased $9.0 million, or 13.5%, to $75.6 million in the six months ended June 30, 2022 as compared to $66.7 million in the six months ended June 30, 2021. The expansion in product revenues was attributable to $5.6 million of growth in sales volume coupled with $4.8 million from favorable pricing in our Nordion segment. Partially offsetting this increase was a $1.3 million unfavorable impact from changes in foreign currency exchange rates.

Total Cost of Revenues

The following table compares our cost of revenues by type for the six months ended June 30, 2022 to the six months ended June 30, 2021.


(thousands of U.S. dollars)
Cost of revenues for the six months ended June 30,	2022		2021		$ Change		% Change

Service	$	192,983	$	176,427	$	16,556	9.4	%
Product	31,139		28,505		2,634		9.2	%
Total cost of revenues	$	224,122	$	204,932	$	19,190	9.4	%

Total cost of revenues accounted for approximately 44.5% and 44.2% of our consolidated net revenues for the six months ended June 30, 2022 and 2021, respectively.

Cost of service revenues

Cost of service revenues increased $16.6 million, or 9.4%, for the six months ended June 30, 2022 as compared to the six months ended June 30, 2021. The increase was attributable to approximately $14.0 million of increased costs arising from inflationary pressures, mainly on labor and the cost of energy. Cost of sales was also impacted by an incremental contribution of $5.9 million from the RCA and BioScience Labs acquisitions in the Nelson Labs segment. Partially offsetting this increase was a $3.9 million impact from changes in foreign currency exchange rates.

Cost of product revenues

Cost of product revenues increased $2.6 million, or 9.2%, for the six months ended June 30, 2022 as compared to the six months ended June 30, 2021. The increase reflects incremental costs due to product mix, offset by impacts from changes in foreign currency exchanges rates.

Operating Expenses

The following table compares our operating expenses for the six months ended June 30, 2022 to the six months ended June 30, 2021:


(thousands of U.S. dollars)
Operating expenses for the six months ended June 30,	2022		2021		$ Change		% Change

Selling, general and administrative expenses	$	122,674	$	102,293	$	20,381	19.9	%
Amortization of intangible assets	31,610		32,204		(594)		(1.8)	%

Total operating expenses	$	154,284	$	134,497	$	19,787	14.7	%

Operating expenses accounted for approximately 30.6% and 29.0% of our consolidated net revenues for the six months ended June 30, 2022 and 2021, respectively.

SG&A

SG&A increased $20.4 million, or 19.9%, for the six months ended June 30, 2022 as compared to the six months ended June 30, 2021. The increase was driven primarily by the following factors:

•$11.7 million increase in litigation and other professional services expense associated with EO sterilization facilities;

•$5.2 million increase in selling and administrative personnel and post-COVID-19 travel costs in support of our general business growth; and

•$3.4 million increase in share-based compensation expense related to our 2020 Omnibus Incentive Plan.

Amortization of intangible assets

Amortization of intangible assets was $31.6 million for the six months ended June 30, 2022, or 1.8% below the six months ended June 30, 2021. The change was due mainly to a reduction in amortization expense related to certain intangible assets that were fully amortized by December 31, 2021, offset by changes in foreign currency exchange rates.

Interest Expense, Net

Interest expense, net decreased $16.0 million, or 39.6%, for the six months ended June 30, 2022 as compared to the six months ended June 30, 2021. The decrease was driven by a $10.7 million reduction to interest expense attributable to the favorable change in fair value and quarterly settlement of interest rate caps not designated as hedging instruments. The decrease was also driven by a decline in interest expense on outstanding borrowings of $5.3 million, due largely to a lower average outstanding debt balance for the six months ended June 30, 2022 compared to the six months ended June 30, 2021 and a lower interest rate on our Term Loan following the January 20, 2021 repricing amendment. The weighted average interest rate on our outstanding debt was 3.81% and 3.45% at June 30, 2022 and 2021, respectively.

Impairment of Investment in Unconsolidated Affiliate

During the six months ended June 30, 2022, we recorded an impairment charge of $9.6 million related to a joint venture investment in Auralux, which was acquired as part of the 2020 Iotron acquisition. Due to a shift in business strategy, the joint venture will not proceed, and our joint venture partner will continue to rely on our other existing operating facilities. Based on these facts and circumstances, we concluded that the investment was impaired as of June 30, 2022.

Foreign Exchange Loss (Gain)

Foreign exchange loss was $0.03 million for the six months ended June 30, 2022 as compared to a loss of $0.7 million in the six months ended June 30, 2021. The change in foreign exchange loss in our Consolidated Statements of Operations and Comprehensive Income (Loss) mainly relates to short-term losses (offset by short-term gains) on sales denominated in currencies other than the functional currency of our operating entities. As described in Note 17, “Financial Instruments and Financial Risk” we enter into monthly U.S. dollar-denominated foreign currency forward contracts to manage foreign currency exchange rate risk of our intercompany loans in certain of our international subsidiaries.

Other Expense (Income), Net

Other expense (income), net was $(2.5) million for the six months ended June 30, 2022 compared to $(6.7) million for the six months ended June 30, 2021. The fluctuation was mainly driven by changes in the fair value of the embedded derivatives in Nordion’s sales and purchase contracts. In addition, for the six months ended June 30, 2021, 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 as compared to the amount previously accrued.

Provision for Income Taxes

Provision for income tax increased $10.1 million to a net provision of $32.3 million for the six months ended June 30, 2022 as compared to a $22.2 million in the six months ended June 30, 2021. The change was principally attributable to pre-tax income of $93.4 million in the six months ended June 30, 2022 compared to pretax income of $75.9 million for the six months ended June 30, 2021. In addition, income tax expense for the six months ended June 30, 2021 was lower due to a discrete item that reversed the valuation allowance on deferred tax assets related to certain asset retirement obligations.

Provision for income taxes for the six months ended June 30, 2022 and for the six months ended June 30, 2021 differed from the statutory rate primarily due to an increase in the valuation allowance, the impact of the foreign rate differential, and tax on GILTI. The increase in the valuation allowance was attributable to the limitation on the deductibility of interest expense and the impairment of the investment in Auralux. Provision for income taxes for the six months ended June 30, 2021 was partially offset by a discrete item, which reversed the valuation allowance on deferred tax assets related to certain asset retirement obligations.

Net Income, Adjusted Net Income and Adjusted EBITDA

Net income for the six months ended June 30, 2022 was $61.1 million, as compared to net income of $53.7 million for the six months ended June 30, 2021. Adjusted Net Income was $136.1 million for the six months ended June 30, 2022, as compared to $123.2 million for the six months ended June 30, 2021, due to the factors described above. Adjusted EBITDA was $251.5 million for the six months ended June 30, 2022, as compared to $239.9 million for the six months ended June 30, 2021, 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 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 and the mark-to-fair value of derivatives not designated as hedging instruments, which includes the embedded derivatives relating to certain customer and supply contracts at Nordion;

•impairment charges on long-lived assets, intangible assets and investments accounted for under the equity method;

•loss on extinguishment of debt incurred in connection with refinancing or early extinguishment of long-term debt;

•expenses and charges related to the litigation and other activities associated with our EO sterilization facilities, including those related to 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 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 gamma irradiation systems 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 June 30, 2022 and 2021

The following tables compare segment net revenue and segment income for the three months ended June 30, 2022 to the three months ended June 30, 2021:


	Three Months Ended June 30,
(thousands of U.S. dollars)	2022			2021			$ Change		% Change

Segment Income margin
Sterigenics	53.9		%	54.8		%
Nordion	59.4		%	63.4		%
Nelson Labs	36.1		%	41.4		%

Net Revenues by Segment

Sterigenics net revenues were $157.8 million for the three months ended June 30, 2022, an increase of $12.6 million, or 8.7%, as compared to the three months ended June 30, 2021. The increase reflects a 6.1% favorable impact from pricing, and volume growth of 5.1%, partially offset by unfavorable impacts from changes in foreign currency exchange rates of 2.5%.

Nordion net revenues were $50.5 million for the three months ended June 30, 2022, an increase of $1.4 million, or 2.8%, as compared to the three months ended June 30, 2021. The increase was primarily attributable to favorable pricing of 6.1% partially offset by a 3.1% unfavorable impact from changes in foreign currency exchange rates.

Nelson Labs net revenues were $58.4 million for the three months ended June 30, 2022, an increase of $0.8 million, or 1.3%, as compared to the three months ended June 30, 2021. Revenue from the RCA acquisition contributed 5.7% and favorable pricing represented 5.4%. Partially offsetting these increases was a 5.0% decline in revenue from reduced demand for pandemic-related testing. In addition, revenue growth was negatively impacted by 2.6% due to changes in foreign currency exchanges rates.

Segment Income

Sterigenics segment income was $85.1 million for the three months ended June 30, 2022, an increase of $5.5 million, or 6.9%, as compared to the three months ended June 30, 2021. The increase in segment income was primarily a result of favorable customer pricing and sales volume growth, as referenced above.

Nordion segment income was $30.0 million for the three months ended June 30, 2022, a decrease of $1.2 million, or 3.8%, as compared to the three months ended June 30, 2021. The decrease in segment income and segment income margin was driven by an unfavorable product mix and changes in foreign currency exchanges rates.

Nelson Labs segment income was $21.1 million for the three months ended June 30, 2022, a decrease of $2.8 million, or 11.6%, as compared to the three months ended June 30, 2021, primarily attributable to the decline in higher margin pandemic-related testing. This decrease was partially offset by the incremental contribution of the RCA acquisition and favorable customer pricing. The 5.3% decrease in segment income margin was driven by recent acquisitions and an unfavorable mix associated with reduced demand for pandemic-related testing.

Segment Results for the Six Months Ended June 30, 2022 and 2021

The following tables compare segment net revenue and segment income for the six months ended June 30, 2022 to the six months ended June 30, 2021:


	Six Months Ended June 30,
(thousands of U.S. dollars)	2022			2021			$ Change		% Change

Net Revenues
Sterigenics	$	307,254		$	276,333		$	30,921	11.2	%

Sterigenics	53.5		%	53.6		%
Nordion	57.9		%	59.9		%
Nelson Labs	34.1		%	41.6		%

Net Revenues by Segment

Sterigenics net revenues were $307.3 million for the six months ended June 30, 2022, an increase of $30.9 million, or 11.2%, as compared to the six months ended June 30, 2021. The increase reflects volume growth of 7.3% and a 5.8% favorable impact from pricing, offset by unfavorable impacts from changes in foreign currency exchange rates of 1.9%.

Nordion net revenues were $84.5 million for the six months ended June 30, 2022, an increase of $9.4 million, or 12.6%, as compared to the six months ended June 30, 2021. The increase was driven by volume growth of 8.4% and a favorable impact from pricing of 6.4%, partially offset by foreign currency impacts of 2.2%.

Nelson Labs net revenues were $111.7 million for the six months ended June 30, 2022, a decrease of $1.0 million, or 0.9%, as compared to the six months ended June 30, 2021. The decrease was mainly attributable to a 7.8% decline in revenue from reduced demand for pandemic-related testing coupled with a decrease in volumes across other testing categories. In addition, revenue was unfavorably impacted by 2.0% due to changes in foreign currency exchanges rates. Partially offsetting this decline was revenue growth from the 2021 acquisitions of RCA and BioScience Labs of 7.0% and a favorable impact from pricing of 4.8%.

Segment Income

Sterigenics segment income was $164.5 million for the six months ended June 30, 2022, an increase of $16.5 million, or 11.1%, as compared to the six months ended June 30, 2021. The increase in segment income was primarily a result of sales volume growth and favorable customer pricing, as referenced above.

Nordion segment income was $48.9 million for the six months ended June 30, 2022, an increase of $3.9 million, or 8.7%, as compared to the six months ended June 30, 2021. The increase in segment income was due to the favorable impacts of volume growth and customer pricing, as referenced above. The decrease in segment income margin was due to an unfavorable product mix.

Nelson Labs segment income was $38.1 million for the six months ended June 30, 2022, a decrease of $8.8 million, or 18.8%, as compared to the six months ended June 30, 2021, primarily attributable to the decline in pandemic-related testing. This decrease was partially offset by the incremental contribution of the BioScience Labs and RCA acquisitions and favorable customer pricing. The 7.5% decrease in segment income margin was driven by unfavorable mix associated with reduced demand for pandemic-related testing, supply chain pressures, labor market constraints, which were compounded by the surge of the Omicron variant in the first quarter of 2022, and dilution resulting from the 2021 Nelson Labs acquisitions.

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 make capital expenditures, including investments in fixed assets to build and/or expand existing facilities, to fund suitable business acquisitions, service our debt, and make expenditures for other general corporate purposes.

As of June 30, 2022, we had $140.6 million of cash and cash equivalents. This is an increase of $33.7 million from the balance at December 31, 2021. Our foreign subsidiaries held cash of approximately $114.7 million at June 30, 2022 and $87.9 million at December 31, 2021. 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, Co-60 development projects and information technology enhancements. During the six months ended June 30, 2022, our capital expenditures amounted to $71.6 million, compared to $44.8 million for the six months ended June 30, 2021.

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, meet foreseeable liquidity requirements, including debt service on our long-term debt, make expected capital expenditures including investments in fixed assets to build and/or expand existing facilities, and meet litigation costs for at least the next twelve months. Our primary long-term liquidity requirements beyond the next twelve months will be to service our debt, make capital expenditures, and fund suitable business acquisitions. As of June 30, 2022, there were no outstanding borrowings on the Revolving Credit Facility. We expect any excess cash provided by operations will be allocated to fund capital expenditures, potential acquisitions, or for other general corporate purposes. 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 June 30, 2022, our interest rate caps limit our cash flow exposure related to LIBOR for the majority of the principal amount outstanding on our variable rate borrowings under the Term Loan. 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 flows provided by operating activities decreased $26.0 million to net cash provided of $108.3 million in the six months ended June 30, 2022 compared to $134.3 million for the six months ended June 30, 2021. The decrease in cash flows from operating activities in the six months ended June 30, 2022 compared to the six months ended June 30, 2021 was driven primarily by an increase in cash paid for taxes of $14.6 million and a $5.4 million increase in cash paid for interest.

Investing activities

Cash used by investing activities increased $0.2 million to net cash used of $71.2 million in the six months ended June 30, 2022 compared to $71.0 million for the six months ended June 30, 2022. Capital expenditures increased $26.9 million in the six months ended June 30, 2022 compared to the six months ended June 30, 2021. 2021 included cash paid for acquisitions of $26.2 million which did not recur in 2022. In 2021, we acquired BioScience Labs for a net purchase price of approximately $13.8 million and we completed the acquisition of the remaining 15% ownership of Nelson Labs Fairfield for $12.4 million.

Financing activities

Cash used for financing activities decreased $11.0 million to net cash used of $1.1 million for the six months ended June 30, 2022 compared to $12.1 million for the six months ended June 30, 2021. The difference was attributable to the payment of $3.7 million of debt issuance costs in the six months ended June 30, 2021 in connection with our January 2021 refinancing of the Senior Secured Credit Facilities (as described in “Debt Facilities” below) and a $7.7 million payment for the acquisition of our Chinese subsidiaries noncontrolling interests.

Debt Facilities

Senior Secured Credit Facilities

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 remain unchanged and the amendment does not change the capacity of our Revolving Credit Facility. 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.

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, 2021. There have been no significant changes in critical accounting policies, management estimates or accounting policies since the year ended December 31, 2021.

NEW ACCOUNTING PRONOUNCEMENTS

For a description of recent accounting pronouncements applicable to our business, see Note 2, “Recent Accounting Standards”.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risks are described within “Quantitative and Qualitative Disclosures About Market Risk” in Part II, Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2021. These market risks have not materially changed for the three and six months ended June 30, 2022.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s “disclosure controls and procedures,” (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (“Exchange Act”)). Based upon their evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures are effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission (“SEC”), and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control

During the three and six months ended June 30, 2022, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II—OTHER INFORMATION

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. At this time, and except as is noted herein, we are unable to predict the outcome of, and cannot reasonably estimate the impact of, any pending litigation matters, matters concerning allegations of non-compliance with laws or regulations and matters concerning other allegations of other improprieties, or the incidence of any such matters in the future. Information regarding our legal proceedings is included below.

Legal Proceedings That Are Not Described in Note 16 “Commitments and Contingencies” to Our Consolidated Financial Statements

In addition to the matters that are identified in Note 16 to our consolidated financial statements for the three and six months ended June 30, 2022 contained in this Quarterly Report on Form 10-Q, and incorporated into this item by reference, the following matter also constitutes a material pending legal proceeding, other than ordinary course litigation incidental to our business, to which we are or any of our subsidiaries is a party.

Zoetermeer, Holland Criminal Proceedings and Criminal Financial Investigation

In 2010, the Dutch Public Prosecution Service started criminal proceedings against DEROSS Holding B.V. (“DEROSS”), in relation to alleged environmental permit violations for EO emissions 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$0.8 million) may be imposed. We have also 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 November 2010, the Public Prosecution Service also started a criminal financial investigation against DEROSS 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 in subsequent confiscation proceedings. The Public Prosecution Service estimates the illegally obtained advantage by DEROSS to be €0.6 million (US$0.6 million).

In February 2018, DEROSS and the two individuals received favorable judgments from the trial court, which did not hold any of them responsible for the alleged criminal offenses. In March 2018, the Public Prosecutor filed an appeal against the favorable judgments. The appeal procedure is still pending.

An escrow account was established in 2011 to satisfy indemnity claims for losses related to this matter. The balance of the special escrow at June 30, 2022, was approximately US$1.8 million and the cash collateral held by ABN Amro to provide security for the claims against us was approximately €2.4 million (US$2.5 million) as of June 30, 2022. 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; 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 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 2021 Form 10-K. Refer to Part I, Item 1A of our 2021 Form 10-K for a detailed discussion of risk factors affecting us.
