Company reaffirms 2022 outlook

CLEVELAND, May 05, 2022 (GLOBE NEWSWIRE) -- 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 financial results for the three months ended March 31, 2022.

First-quarter 2022 net revenues increased 12% to $237 million, compared with $212 million in the first quarter a year ago. Net income attributable to Sotera Health ("net income") was $31 million, or $0.11 per diluted share, compared with net income of $11 million, or $0.04 per diluted share in the first-quarter 2021. Adjusted EBITDA for the first-quarter 2022 increased by 10% over the prior-year quarter to $115 million. First-quarter 2022 Adjusted Earnings Per Diluted Share ("Adjusted EPS") was $0.22, compared to $0.18 in Q1 2021, an increase of $0.04 per diluted share. Please refer to the section "Non-GAAP Financial Measures" provided later in this release.

"We are off to a good start in 2022, delivering another consecutive quarter of double-digit top-line and bottom-line growth as compared to the same prior year quarter," said Chairman and Chief Executive Officer, Michael B. Petras, Jr. "We are pleased with the first-quarter performance as we navigated through the Omicron surge and the current geopolitical landscape. We continue to focus on execution while strategically building out capacity to satisfy future demand."

Petras continued, "Given our performance to date, we are reaffirming the 2022 financial outlook that we first provided on March 1, 2022. We remain focused on supporting our global team members and customers while delivering on our mission of Safeguarding Global Health®."

First-Quarter Review by Business Segment

Sterigenics

For first-quarter 2022, Sterigenics net revenues were $149 million, an increase of 14.0% compared to the first quarter a year ago. Segment income was $79 million, an increase of 16.0%.

Net revenues and segment income growth for the first-quarter 2022 were driven by volume and mix, and pricing.

Nordion

For first-quarter 2022, Nordion net revenues were $34 million, an increase of 31.2% compared to the first quarter a year ago. Segment income increased 37.1% to $19 million.

The increases in both net revenues and segment income for the first-quarter 2022 were driven by volume and mix, and pricing.

Nelson Labs

For first-quarter 2022, Nelson Labs net revenues were $53 million, a decrease of 3.2% compared to the first quarter a year ago. Segment income decreased by 26.1% to $17 million.

The decline in net revenues for the first-quarter 2022 was driven by decreased demand for pandemic-related testing, partially offset by incremental revenue from recent acquisitions and pricing. Segment income decline was driven by unfavorable mix due to a reduction in pandemic-related testing, labor challenges, which were compounded by the Omicron surge, as well as dilution resulting from Nelson Labs' acquisitions in 2021.

Balance Sheet and Liquidity

As of March 31, 2022, Sotera Health had $1.79 billion in total debt, and $121 million in cash and cash equivalents, compared to $1.79 billion in total debt and $107 million in cash and cash equivalents as of December 31, 2021. Sotera Health's net leverage ratio as of March 31, 2022 improved to 3.4x. Please refer to the section "Non-GAAP Financial Measures" provided later in this release.

Reaffirming 2022 Outlook

Today, Sotera Health is reaffirming the 2022 outlook first provided on March 1, 2022. That outlook is:

Net revenues in the range of $1.0 billion to $1.03 billion, 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. 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 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, or increases in the price 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 basis for the 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.
