CLEVELAND, May 03, 2023 (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, 2023.

First-quarter 2023 net revenues decreased 6.8% to $221 million, compared with $237 million in the first-quarter 2022. Net revenues decreased 5.3% on a constant currency basis. Net income (“net income”) was $3 million, or $0.01 per diluted share, compared with net income of $31 million, or $0.11 per diluted share in the first-quarter 2022. Adjusted EBITDA for the first-quarter 2023 decreased by 14.6% to $98 million compared to $115 million in the first-quarter 2022. First-quarter 2023 Adjusted Earnings Per Diluted Share (“Adjusted EPS”) was $0.13, compared to $0.22 in the first-quarter 2022. Adjusted EBITDA and Adjusted EPS are non-GAAP financial measures; please refer to the section “Non-GAAP Financial Measures” provided later in this release.

“As we outlined in our fourth-quarter 2022 earnings call, our first-quarter total revenue was below the same quarter last year, driven by the anticipated timing of Nordion Cobalt-60 harvest schedules and lower volumes for the Nelson Labs and Sterigenics businesses, which is typical for the first quarter of the year,” said Chairman and Chief Executive Officer, Michael B. Petras, Jr. “We continue to expect financial contribution from Sterigenics and Nelson Labs to increase as we move through the year, in a similar cadence to prior years. Additionally, we are still forecasting Nordion’s Cobalt-60 harvest schedules to be uneven, with approximately 75% of Nordion’s full-year revenue occurring in the back half of the year.”

Petras continued, “Looking to the remainder of the year, we feel good about how we are positioned and are reaffirming the 2023 revenue and adjusted EBITDA growth outlook of 5% to 9% that we first provided in February. As always, 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 2023, Sterigenics’ net revenue was $160 million, an increase of 7.0% compared to the first quarter a year ago. Segment income was $83 million, an increase of 4.3%.

Net revenue and segment income growth for the first-quarter 2023 were driven by favorable pricing as well as volume and mix, partially offset by unfavorable changes in foreign currency exchange rates.

Segment income margin decline was driven by the impacts referenced above, offset by the impact of current staffing levels versus the typical lighter first-quarter volume relative to the remainder of the year, as well as inflation.

Nordion

For first-quarter 2023, Nordion net revenue was $9 million, a decrease of 74.9% compared to the first quarter a year ago. Segment income decreased 91.9% to $2 million.

The decreases in net revenue, segment income and segment income margin for the first-quarter 2023 were driven by anticipated volume decline and change in mix due to Cobalt-60 (“Co-60”) harvest schedule timing, and an unfavorable impact from changes in foreign currency exchange rates.

Nelson Labs

For first-quarter 2023, Nelson Labs net revenue was $52 million, a decrease of 2.3% compared to the first quarter a year ago. Segment income decreased by 17.3% to $14 million.

The decline in net revenue for the first-quarter 2023 was driven by volume decline and change in mix and an unfavorable impact from changes in foreign currency exchange rates, partially offset by favorable pricing.

Segment income and segment income margin declines were driven by the factors referenced above, as well as the impact of current staffing levels versus the typical lighter first-quarter volume relative to the remainder of the year.

Balance Sheet and Liquidity

As of March 31, 2023, Sotera Health had $2.3 billion in total debt, and $648 million in cash and cash equivalents, compared to $2.0 billion in total debt and $395 million in cash and cash equivalents as of December 31, 2022. The Company closed on a $500 million Term Loan B during the first-quarter 2023, which along with cash on hand, was used to pay off the $200 million of borrowings under the Company’s revolving credit facility and to fund into escrow the $408 million related to the ethylene oxide (“EO”) settlement (the “Illinois EO Settlement”), which occurred on May 1, 2023. The Company used the remaining proceeds to further enhance liquidity and for general corporate purposes. The $408 million will be held as restricted cash on the balance sheet in the second-quarter 2023. During the first quarter, the Company also closed on an amendment to its First Lien Credit Agreement, which added revolving loan commitments of $76.3 million and increased the total aggregate principal amount of available commitments to $423.8 million. As of March 31, 2023 the Company had no balance outstanding on its revolving credit facility. Sotera Health’s net leverage ratio as of March 31, 2023 was 3.4x. Please refer to the section “Non-GAAP Financial Measures” provided later in this release.

Reaffirming 2023 Outlook

Today, Sotera Health is reaffirming the 2023 outlook first provided on February 28, 2023. That outlook is:

• 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 a 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 EO and Co-60, the impact of inflationary trends including the impact on energy prices and the supply of labor, and the expectation that exchange rates as of March 31, 2023 remain constant for the remainder of 2023. 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 “Cautionary Note Regarding Forward-Looking Statements.”

Cautionary Note Regarding 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 Illinois EO tort litigation, which if the Illinois EO 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. 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 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.
