Please refer to the section “Non-GAAP Financial Measures” provided later in this release.

For full-year 2021, net revenues increased 13.9% to $931 million, compared with $818 million for full-year 2020. Full-year 2021 net income was $117 million, or $0.41 per diluted share, compared with a net loss of $39 million, or $(0.16) per diluted share, for full-year 2020.

“This past year has been an exceptional one for Sotera Health as we navigated a challenging macro environment,” said Chairman and Chief Executive Officer, Michael B. Petras, Jr. “During 2021, we executed on a number of initiatives to position ourselves well for the future, which included organic investments in our facility network to better meet our customers’ needs, two tuck-in acquisitions, the creation of our Expert Advisory Services organization, the launch of a formal ESG initiative, and a significant reduction of our leverage to further strengthen our balance sheet.”

Petras continued, “We are pleased to report another quarter of strong top-line, net income, and Adjusted EBITDA growth, which translated to double-digit revenue and Adjusted EBITDA growth for both the quarter and full-year. We have now delivered double-digit revenue and Adjusted EBITDA growth in all 5 periods that we have reported as a public company. I am extremely proud of the Sotera Health team and look forward to another strong year in 2022. Our excitement for 2022 is anchored by a significant escalation in our investment in capacity expansions, which demonstrates the strength we see in long-term customer demand for our services.”

Fourth-Quarter and Full-Year 2021 Review by Business Segment

Sterigenics

For fourth-quarter 2021, net revenues from Sterigenics were $150 million, an increase of 11.4% compared to the fourth quarter a year ago. Segment income was $83 million, an increase of 12.5%.

For full-year 2021, Sterigenics net revenues were $572 million, an increase of 14.6% compared to 2020. Segment income increased 16.4% to $310 million.

Revenue and segment income growth for both the fourth-quarter and full-year 2021 were driven by organic volume growth and favorable pricing, while full-year results also benefited from the July 31, 2020 Iotron acquisition.

Nordion

For fourth-quarter 2021, net revenues from Nordion were $37 million, an increase of 27.8%, compared to the fourth quarter a year ago. Segment income increased 32.8% to $21 million.

For full-year 2021, net revenues from Nordion were $141 million, an increase of 22.5% compared to 2020. Segment income increased by 23.8% to $83 million.

Revenue and segment income growth for both the fourth-quarter and full-year 2021 were primarily driven by volume growth, a favorable impact from pricing and changes in foreign exchange rates.

Nelson Labs

For fourth-quarter 2021, net revenues from Nelson Labs were $54 million, an increase of 2.0% compared to the fourth quarter a year ago. Segment income declined 12.6% to $20 million.

For full-year 2021, net revenues from Nelson Labs were $219 million, an increase of 7.1% compared to 2020. Segment income increased 1.9% to $88 million.

Revenue and segment income changes for both the fourth-quarter and full-year 2021 were driven by the acquisitions of BioScience Labs and Regulatory Compliance Associates (“RCA”) and favorable pricing offset by a decline in demand for testing related to new personal protective equipment.

Balance Sheet and Liquidity

As of December 31, 2021, Sotera Health had $1.8 billion in total debt, and $107 million in cash and cash equivalents, compared to $1.9 billion in total debt and $102 million in cash and cash equivalents as of December 31, 2020. Material debt balances currently outstanding do not mature until 2026. Sotera Health’s net leverage ratio as of December 31, 2021 was 3.5x, compared to 4.3x at December 31, 2020. Please refer to the section “Non-GAAP Financial Measures” provided later in this release.

Full-Year 2022 Outlook

Today, Sotera Health is providing its full-year 2022 outlook:

• Net revenues in the range of $1,000 million to $1,030 million, representing growth of approximately 7% to 11%, compared to the prior year,
• Adjusted EBITDA in the range of $515 million to $535 million, representing growth of approximately 7% to 11%, compared to the prior year,
• Tax rate applicable to Adjusted Net Income in the range of 29% to 30%,
• Adjusted EPS in the range of $0.93 to $0.99, representing growth of 6% to 13% versus the prior year,
• A fully diluted share count in the range of 280 million to 282 million shares on a weighted-average basis,
• Capital expenditures in the range of $140 million to $170 million, and
• Net leverage reduction of approximately 1/2 of a turn.
  

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 the impact on the supply of labor, the impact of the COVID-19 pandemic including the rate of recoveries of elective procedures and new product development testing, and the expectation that exchange rates as of Q1 2022 remain constant for the remainder of 2022. Our outlook is based on current plans and expectations and is subject to a number of known and unknown risks and uncertainties, including those set forth below under “Forward-Looking Statements.”

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. Any forward-looking statements contained in this release are based upon our historical performance and on our current plans, estimates and expectations 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 EO or Co-60, including geopolitical risks related to the supply of Co-60 from Russia; changes in industry trends, environmental, health and safety regulations or preferences; 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; 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 Company’s filings with the SEC, such as its annual and quarterly reports. 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

The Company does not provide a reconciliation of the forward-looking Adjusted EBITDA, Adjusted Net Income, Adjusted EPS, and Net Leverage Ratio outlook to the most directly comparable GAAP measure, as this cannot be done without unreasonable effort due to the variability and low visibility with respect to certain items, including, among others, uncertainties caused by the global COVID-19 pandemic, changes to the regulatory landscape, restructuring items and certain fair value measurements, all of which are potential adjustments for future earnings. The variability of these items could have a potentially unpredictable, and a potentially significant, impact on our future GAAP results.

To supplement our consolidated financial statements presented in accordance with GAAP, we consider Adjusted EBITDA, Adjusted Net Income, Adjusted EPS, Net Debt and Net Leverage Ratio, 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.

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 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.
