For full-year 2022, Sterigenics net revenues were $627 million, an increase of 9.6% compared to 2021. Segment income increased 9.2% to $339 million.

Revenue and segment income growth for fourth-quarter 2022 were driven by favorable pricing and organic volume growth, offset by an unfavorable impact from changes in foreign exchange rates.

Revenue and segment income declines for fourth-quarter 2022 were primarily driven by the timing of reactor harvest schedules and an unfavorable impact from changes in foreign exchange rates, partially offset by a favorable impact from pricing.

Nelson Labs

For fourth-quarter 2022, net revenues were $56 million, an increase of 2.7% compared to the fourth quarter a year ago. Segment income increased less than 1% to $20 million.

For full-year 2022, Nelson Labs net revenues were $223 million, an increase of 1.9% compared to 2021. Segment income decreased 11.9% to $78 million.

Revenue and segment income increases for the fourth-quarter 2022 were driven by favorable pricing, partially offset by an unfavorable impact from changes in foreign currency exchange rates.

Balance Sheet and Liquidity

As of December 31, 2022, Sotera Health had $2.0 billion in total debt, and $396 million in cash and cash equivalents, compared to $1.8 billion in total debt and $107 million in cash and cash equivalents as of December 31, 2021. The Company's debt balance includes $200 million borrowed on the Company's revolving credit facility in fourth-quarter 2022 in connection with the EO litigation. Material debt balances currently outstanding do not mature until 2026. Sotera Health's Net Leverage Ratio as of December 31, 2022 was 3.2x, compared to 3.5x at December 31, 2021. Net Leverage Ratio is a non-GAAP financial measures; please refer to the section "Non-GAAP Financial Measures" provided later in this release.

The first-quarter closing of the $500 million aggregate principal amount Term Loan B, along with cash on hand, will be used to fund the $408 million EO settlement, pay down existing borrowings under the Company's revolving credit facility, further enhance liquidity, and for other general corporate purposes. The $500 million Term Loan B will impact the Company's Net Leverage Ratio. Please refer to the section "Non-GAAP Financial Measures" provided later in this release for a discussion on Net Leverage Ratio.

Full-Year 2023 Outlook

Today, Sotera Health is providing its full-year 2023 outlook:

Net revenues in the range of $1.055 to $1.090 billion, representing growth of approximately 5% to 9%, compared to the prior year,
Adjusted EBITDA in the range of $530 to $550 million, representing growth of approximately 5% to 9%, compared to the prior year,
Tax rate applicable to Adjusted Net Income in the range of 30% to 33%,
Adjusted EPS in the range of $0.78 to $0.86, representing decline of 10% to 19% versus the prior year, primarily driven by increased interest expense and an increased tax rate,
A fully diluted share count in the range of 283 to 285 million shares on a weighted-average basis,
Capital expenditures in the range of $185 to $215 million, and
2023 year-end Net Leverage Ratio to be within the long-term stated range of 2.0x - 4.0x.

The Company does not provide a reconciliation for non-GAAP financial measures on a forward-looking basis where it is unable to provide a meaningful or accurate calculation or estimation of reconciling items without unreasonable effort. The Company cannot reconcile its expected Adjusted EBITDA, Adjusted Net Income, Adjusted EPS and Net Leverage Ratio without unreasonable effort because certain items that impact net income, earnings per share and other reconciling metrics are out of the Company's control and/or cannot be reasonably predicted at this time, including uncertainties caused by changes to the regulatory landscape, restructuring items and certain fair value measurements, all of which are potential adjustments for future earnings.

The outlook provided above contains a number of assumptions, including, among others, the Company's current expectations regarding supply chain continuity, particularly for the supply of ethylene oxide ("EO") and cobalt-60 ("Co-60"), the impact of inflationary trends including their impact on energy prices and the supply of labor and the expectation that exchange rates as of December 31, 2022 remain relatively constant for the remainder of 2023. Our outlook is based on current plans and expectations and is subject to several known and unknown risks and uncertainties, including those set forth below under "Forward-Looking Statements."

Unless expressly indicated or the context requires otherwise, the terms "Sotera Health," "Company," "we," "us," and "our" in this document refer to Sotera Health Company, a Delaware corporation, and, where appropriate, its subsidiaries on a consolidated basis. This release contains forward-looking statements that reflect management's expectations about future events and the Company's operating plans and performance and speak only as of the date hereof. You can identify these forward-looking statements by the use of forward-looking words such as "will," "may," "plan," "estimate," "project," "believe," "anticipate," "expect," "intend," "should," "would," "could," "target," "goal," "continue to," "positioned to," "are confident" or the negative version of those words or other comparable words. In addition, any statements that refer to expectations, projections or other characterizations of future events or circumstances, are forward-looking statements. Any forward-looking statements contained in this release are based upon our historical performance and on our current plans, estimates and expectations of the Company's future performance and the future performance of the markets in which the Company operates in light of information currently available to us. The inclusion of this forward-looking information should not be regarded as a representation by us that the future plans, estimates or expectations contemplated by us will be achieved. 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 EO or 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 Illinois EO 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, or may cause the need for us to increase our borrowings and, consequently, increase our interest expense; uncertainty in the capital markets and other risks 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 the Company's filings with the SEC, such as its annual and quarterly reports, 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 Illinois settlement. We do not undertake any obligation to publicly update or revise these forward-looking statements, except as otherwise required by law.

Non-GAAP Financial Measures

To supplement our consolidated financial statements presented in accordance with GAAP, we consider Adjusted EBITDA, Adjusted Net Income, Adjusted EPS, Net Debt, Net Leverage Ratio and constant currency, financial measures that are not based on any standardized methodology prescribed by GAAP.

We define Adjusted Net Income as net income (loss) before amortization and certain other adjustments that we do not consider in our evaluation of our ongoing operating performance from period to period.

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. Adjusted EBITDA Margin is equal to Adjusted EBITDA divided by net revenues.

We define Adjusted EPS as Adjusted Net Income divided by the weighted average number of diluted shares outstanding.

Our Net Debt is equal to our total debt, plus unamortized debt issuance costs and debt discounts, less cash and cash equivalents.

Our Net Leverage Ratio is equal to Net Debt divided by Adjusted EBITDA.

Constant currency is a non-GAAP financial measure we use to assess performance excluding the impact of foreign currency exchange rate changes. We calculate constant currency net revenues by translating prior year net revenues in local currency at the average exchange rates applicable for the current period. The translated results are then used to determine year-over-year percentage increases or decreases. We generally refer to such amounts calculated on a constant currency basis as excluding the impact of foreign currency exchange rates. These results should be considered in addition to, not as a substitute for, results reported in accordance with GAAP. Results on a constant currency basis, as we present them, may not be comparable to similarly titled measures used by other companies and are not measures of performance presented in accordance with U.S. GAAP.

We use these non-GAAP financial measures as the principal measures of our operating performance. Management believes these 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 these measures 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 these measurements in their financial analysis and operational decision-making and Adjusted EBITDA serves as the key metric for attainment of our primary annual incentive program. These measures may be calculated differently from, and therefore may not be comparable to, a similarly titled measure used by other companies.
