Sotera Health Confirms Preliminary 2022 Full-Year Guidance

in Conjunction with Incremental Debt Financing

Cleveland, Ohio February 13, 2023 – Sotera Health Company (“Sotera Health” or the “Company”) (NASDAQ: SHC), a leading global provider of mission-critical end-to-end sterilization solutions, lab testing and advisory services for the healthcare industry, today announced its intention to enter into a new senior secured Term Loan B facility in an aggregate principal amount of $425 million, which is expected to fund and close during the first quarter. The Company plans to use proceeds of this debt financing, along with cash on hand, to: a) fund a previously announced planned $408 million ethylene oxide litigation settlement in Cook County, IL, b) pay down existing borrowings under the Company’s revolving credit facility, and c) further enhance liquidity.

Preliminary Financial Results for the Year Ended December 31, 2022

Our financial statements for the year ended December 31, 2022 are not yet complete. Accordingly and related to this incremental debt financing, we are presenting preliminary estimates of certain financial information that we expect to report on February 28, 2023 for the year ended December 31, 2022. The following information is based on our internal management accounts and reporting as of and for the year ended December 31, 2022, as compared to our audited results for the year ended December 31, 2021. Given the timing of these estimates, we have not completed our customary financial closing and review procedures but are making these estimates available to facilitate the incremental debt financing.

The Company is reaffirming its expectation that 2022 full-year net revenues will be within the previously announced guidance range of $995 million to $1.005 billion. The Company also is announcing that the 2022 full-year net loss is expected to be in a range of $226 million to $236 million, which includes a $408 million legal reserve recorded in Q4 2022 related to the binding term sheets to settle 870+ ethylene oxide claims in Cook County, IL, subject to the satisfaction or waiver of the various conditions set forth in the term sheets. Full-year Adjusted EBITDA will be in the previously announced guidance range of $500 million to $510 million. Adjusted EBITDA is a non-GAAP financial measure; a reconciliation of Adjusted EBITDA to its most closely comparable GAAP figure is included at the end of this release.

The preliminary financial information included in this release has been prepared by, and is the responsibility of, the Company’s management. The preliminary estimated results of operations are subject to revision as we finalize our financial statements and disclosure for the year ended December 31, 2022, and such revisions may be significant. Estimates of financial results are inherently uncertain and we undertake no obligation to update this information before announcement of final results for 2022.

In connection with our annual closing and review process for the fiscal year 2022, we may identify items that would require us to make adjustments to the preliminary estimated results of operations set forth in this release. Accordingly, the final results and other disclosures for the year ended December 31, 2022 may differ materially from the preliminary estimates being announced today. This preliminary estimated financial data should not be viewed as a substitute for financial statements prepared in accordance with U.S. GAAP. The Company expects to file its Annual Report on Form 10-K for the year ended December 31, 2022 on February 28, 2023, its previously announced reporting date. Ernst & Young LLP, our independent registered public accounting firm, has not audited, reviewed, compiled, or applied agreed-upon procedures with respect to the preliminary estimated financial data for the year ended December 31, 2022 that we are presenting here. Accordingly, Ernst & Young LLP does not express an opinion or any other form of assurance with respect thereto.

Non-GAAP Financial Measures

To supplement our consolidated financial statements presented in accordance with GAAP, we consider Adjusted EBITDA, a financial measure that is not based on any standardized methodology prescribed by GAAP.

We define Adjusted EBITDA as net income (loss) before interest expense and the mark-to-market impact of derivatives not accounted for as hedges, income taxes, depreciation (including depreciation of Co-60 used in our operations), amortization of intangible assets and certain other adjustments that we do not consider in our evaluation of our ongoing operating performance from period to period.

In evaluating Adjusted EBITDA, you should be aware that, in the future, we will incur expenses similar to the adjustments in this presentation. Our presentation of 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 EBITDA alongside other financial performance measures, including our net income and other GAAP measures.

These forward-looking statements are subject to various risks, uncertainties and assumptions relating to our operations, financial results, financial condition, business, prospects, growth strategy and liquidity. These risks and uncertainties include, without limitation, any disruption in the availability or supply of, or increases in the price of, ethylene oxide (“EO”) or cobalt-60 (“Co-60”), including geopolitical risks related to the supply of Co-60 from Russia; foreign currency exchange rates and changes in those rates; changes in industry trends, environmental, health and safety regulations or preferences; satisfaction of conditions to completing the settlement, including the participation by substantially all Illinois plaintiffs in the settlement; the impact of current and future legal proceedings and liability claims, including litigation related to purported exposure to emissions of EO from our facilities in Illinois, Georgia and New Mexico and the possibility that other claims will be made in the future relating to these or other facilities; adverse judgments against two of our subsidiaries in the EO tort litigation, which if the settlement is not successful may require an appellate bond or alternative form of security to appeal, and plaintiff efforts to enforce judgments against us, any of which may have an adverse impact on our liquidity in the near and long terms; whether we will be able to close the new Term Loan B facility on expected terms or at all; uncertainty in the capital markets and other risks related to our ability to raise additional debt financing on reasonable terms or at all, including availability of capital and the impact of future litigation developments on our ability to access capital markets; our ability to increase capacity at existing facilities, renew leases for our leased facilities and build new facilities in a timely and cost-effective manner; competition for qualified employees in the industries in which we operate; the risks of doing business internationally; and any inability to pursue strategic transactions or find suitable acquisition targets. For additional discussion of these risks and uncertainties, please refer to those described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, and the Company’s other filings with the SEC, including its Quarterly Reports on Form 10-Q, including under the headings “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” as well as the Current Report on Form 8-K filed by the Company on January 9, 2023 with the SEC disclosing the terms of the settlement and related risks.
