CLEVELAND, Aug. 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 and six months ended June 30, 2023.

Second-quarter 2023 net revenues decreased 4.3% to $255 million, compared with $267 million in the second-quarter 2022. Net income was $24 million, or $0.08 per diluted share, compared with net income of $30 million, or $0.11 per diluted share in the second-quarter of 2022. Adjusted EBITDA for the second-quarter 2023 decreased 5.6% to $128 million compared to $136 million in the second-quarter 2022. Second-quarter 2023 Adjusted Earnings Per Diluted Share (“Adjusted EPS”) was $0.21, compared to $0.27 in the second quarter of 2022. Please refer to the section “Non-GAAP Financial Measures” provided later in this release.

For the first six months of 2023, net revenues decreased 5.5% to $476 million, compared to $503 million for the same period in 2022. Net revenues decreased approximately 4.6% on a constant currency basis. Net income was $26 million, or $0.09 per diluted share for the first half of 2023, compared with net income of $61 million, or $0.22 per diluted share, for the same period last year. Adjusted EBITDA for the first half of 2023 decreased 9.8% to $227 million and Adjusted EPS decreased by $0.15 to $0.34 compared to the first half of 2022. Please refer to the section “Non-GAAP Financial Measures” provided later in this release.

“The team has been working diligently to execute on our strategy in a challenging environment,” said Chairman and Chief Executive Officer, Michael B. Petras, Jr. “All three business units have achieved significant margin expansion versus the first quarter of this year while Nordion has done an excellent job navigating the complexities of cobalt-60 logistics. Additionally, we are pleased to have completed the settlement of the Illinois EO litigation ahead of schedule with a 99.7% participation rate.”

Petras continued, “While second-quarter results were impacted by comparisons to record-setting revenue quarters for Nordion and Nelson Labs in the prior year, we are experiencing continued volume softness at both Sterigenics and Nelson Labs. We now expect the volume softness to continue and therefore have adjusted our 2023 outlook for net revenues to be in the range of $1.035 billion to $1.055 billion, and Adjusted EBITDA to be in the range of $520 million to $535 million. We are confident in this revised range and will continue to concentrate on executing our strategy. As always, our focus continues to be on providing high-quality service to our customers, while remaining committed to our mission, Safeguarding Global Health®.”

• Adjusted EBITDA in the range of $520 to $535 million, from previous guidance of $530 million to $550 million, representing growth of approximately 3% to 6%, compared to the prior year,

• Tax rate applicable to Adjusted Net Income in the range of 30% to 32%, from previous guidance of 30% to 33%,

• Adjusted EPS remains in the range of $0.78 to $0.86,

• A fully diluted share count remains in the range of 283 million to 285 million shares on a weighted-average basis,

• Capital expenditures in the range of $200 to $215 million, from previous guidance of $185 to $215 million, and

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 Cobalt-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 June 30, 2023 remain 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 “Cautionary Note Regarding Forward-Looking Statements.”

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 Cobalt-60 (“Co-60”), or our other direct materials, services and supplies, including as a result of geopolitical instability and sanctions arising from US, Canadian, UK or European Union relations with Russia; foreign currency exchange rates and changes in those rates; adverse changes in industry trends, environmental, health and safety regulations or preferences, or general economic, social and business conditions; the impact and outcome 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, including global and regional economic and political instability and compliance with numerous laws and regulations in multiple jurisdictions; and any inability to pursue strategic transactions or find suitable acquisition targets.

Non-GAAP Financial Measures.

To supplement our consolidated financial statements presented in accordance with GAAP, we consider Adjusted EBITDA, Adjusted EBITDA margin, 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 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.

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 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 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.
