CLEVELAND, May 05, 2026 (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, 2026.

“We delivered a strong start to the year, with solid revenue and Adjusted EBITDA growth while driving margin expansion,” said Chairman and Chief Executive Officer, Michael B. Petras, Jr. “Growth was driven by disciplined execution at Sterigenics and Nordion, and Nelson Labs came in as we outlined on our fourth-quarter 2025 earnings call. Based on our first-quarter performance, we are reaffirming our 2026 outlook and remain confident in our trajectory for the remainder of the year.”

Petras continued, “In addition to adding Rich Kyle to our Board of Directors in February, we are also excited to welcome Ken Krause, who joined our Board in March. Ken’s leadership and proven track record of creating shareholder value as a public company chief financial officer for over 10 years, and his extensive experience in strategy, finance and governance will be tremendous assets as we continue to grow.”

First-Quarter 2026 Highlights
(All comparisons are against first quarter of 2025, unless otherwise noted)

• Delivered solid top- and bottom-line constant currency revenue growth
• Expanded Adjusted EBITDA margins
• Sterigenics: 6.1% constant currency revenue growth, driven by price and volume/mix
• Nordion: 25.8% constant currency revenue growth; margin improvement of over 290 basis points
• Nelson Labs: constant currency revenue and segment income margins as expected
• Net cash provided by operating activities of $29 million, inclusive of a previously disclosed $34 million legal settlement
• As of March 31, 2026, Net Leverage Ratio⁽¹⁾ of 3.2x and over $900 million in available liquidity

First-Quarter Review by Business Segment
(All comparisons are against first quarter of 2025, unless otherwise noted)

Sterigenics

Sterigenics delivered solid first-quarter 2026 results, with net revenues up 9.7% to $186 million, or 6.1% on a constant currency basis. Segment income was $96 million, an increase of 9.6%.

Net revenues growth was driven by favorable pricing, foreign currency benefits and improved volume/mix. Segment income was also driven by these factors, partially offset by higher costs.

Nordion

Nordion first quarter net revenues were up 29.0% to $42 million, or 25.8% on a constant currency basis while segment income increased 36.1% to $24 million.

Net revenues growth was driven by volume/mix benefits due to timing of cobalt-60 harvest schedules, as well as foreign currency tailwinds and favorable pricing. Segment income and segment income margin growth were also driven by these factors, partially offset by inflation.

Nelson Labs

Nelson Labs first quarter net revenues were $52 million, a decrease of 0.7%, or 3.8% on a constant currency basis while segment income decreased 11.5% to $15 million.

Net revenues, segment income and segment income margin differences were driven by unfavorable volume/mix, partially offset by foreign currency benefits and favorable pricing.

Reaffirming 2026 Outlook

The 2026 outlook below, first provided on February 24, 2026, remains unchanged:

• Net revenues in the range of $1.233 billion to $1.251 billion, representing constant currency growth of 5.0% to 6.5% and an estimated 100bps foreign currency benefit
• Adjusted EBITDA in the range of $632 million to $641 million, representing constant currency growth of 5.5% to 7.0% and an estimated 100bps foreign currency benefit
• Interest expense in the range of $135 million to $145 million
• Tax rate applicable to Adjusted Net Income⁽¹⁾ in the range of 27.0% to 29.0%
• Adjusted EPS in the range of $0.93 to $1.01
• A weighted-average fully diluted share count in the range of 289 million to 291 million shares
• Capital expenditures in the range of $175 million to $225 million
  
  

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 Tax Rate, Adjusted Net Income and Adjusted EPS 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, and the impact of inflationary trends including their impact on energy prices and the supply of labor. 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 “Cautionary Note Regarding Forward-Looking Statements.”

This release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and reflects management’s expectations about future events and the Company’s operating plans and performance and speak only as of the date hereof. Forward-looking statements present our current forecasts and estimates of future events. These statements do not strictly relate to historical or current results and can be identified by words such as “anticipate,” “appear,” “assume,” “believe,” “estimate,” “expect,” “forecast,” “intend,” “likely,” “may,” “plan,” “project,” “seek,” “should,” “strategy,” “will” and other terms of similar meaning or import in connection with any discussion of future operating, financial or other performance. These forward-looking statements are subject to risks, uncertainties and other factors and actual results may differ materially from those results projected in the statements. 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, but are not limited to, a disruption in the availability or supply of, or increases in the price of, EO, Co-60 or our other direct materials, services and supplies, including as a result of geopolitical instability and/or sanctions against Russia by the United States, Canada, the United Kingdom and/or the European Union, or sanctions by Russia against those countries; fluctuations in foreign currency exchange rates; evolving changes in environmental, health and safety regulations; health and safety risks associated with the use, storage, transportation and disposal of potentially hazardous materials such as EO and Co-60; the impact and outcome of current and future legal proceedings and liability claims, including litigation related to the use, emissions and releases of EO from our current and former EO sterilization facilities and the possibility that additional claims will be made in the future; allegations of our failure to properly perform services and potential product liability claims, recalls, penalties and reputational harm; compliance with the extensive regulatory requirements to which we are subject, the related costs, and any failures to receive or maintain, or delays in receiving, required clearances or approvals; adverse changes in industry trends; competition we face; market conditions and changes, including inflationary trends and the impact of tariffs, that impact our long-term supply contracts with variable price clauses and increase our cost of revenues; business continuity hazards, including supply chain disruptions, federal government shutdowns, and other risks associated with our operations; the risks of doing business internationally, including global and regional economic and political instability and compliance with various applicable laws and potentially inconsistent laws and regulations in multiple jurisdictions; our ability to increase capacity at existing facilities, build new facilities in a timely and cost-effective manner and renew leases for our leased facilities; our ability to attract and retain qualified employees; severe health events or environmental events; cybersecurity incidents, unauthorized data disclosures, and our dependence on information technology systems; the risks associated with the introduction of artificial intelligence technology; an inability to pursue strategic transactions, find suitable acquisition targets, or integrate strategic acquisitions into our business successfully; our ability to maintain effective internal control over financial reporting; our reliance on intellectual property rights to maintain our competitive position and the risk of claims from third parties that we have infringed or misappropriated, or are infringing or misappropriating, their intellectual property rights; our ability to comply with rapidly evolving data privacy and security laws and regulations in various jurisdictions and any ineffective compliance efforts with such laws and regulations; our ability to generate profitability in future periods; impairment charges on our goodwill and other intangible assets with indefinite lives, as well as other long-lived assets and intangible assets with definite lives; the effects of unionization efforts and labor regulations in countries in which we operate; adverse changes to our tax positions in U.S. or non-U.S. jurisdictions or the interpretation and application of U.S. tax legislation or other changes in U.S. or non-U.S. taxation of our operations; our significant degree of leverage and how this leverage could adversely affect our ability to raise additional capital, limit our ability to react to challenges facing our Company or broader changes in our industry or the economy, limit our flexibility in operating our business through restrictions contained in our debt agreements and/or prevent us from meeting our obligations under our existing and future agreements governing our indebtedness; and the influence that certain investment funds and entities affiliated with Warburg Pincus and GTCR continue to have over us. For additional discussion of these risks and uncertainties, please refer to the Company’s filings with the Securities and Exchange Commission, such as its Annual Report on Form 10-K 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 EBITDA margin, Adjusted Tax Rate, Adjusted Net Income, Adjusted EPS, Segment income margin, Net Debt and 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 Cobalt-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.
• Segment income margin is equal to segment income divided by net segment 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 measures 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 without these measures and their 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 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.
