Third-quarter 2024 net revenues increased 8.5% to $285 million, compared with $263 million in the third-quarter 2023. Net revenues increased 8.9% on a constant currency basis. Net income was $17 million, or $0.06 per diluted share, compared to a net loss of $14 million, or $0.05 per diluted share in the third-quarter of 2023. Adjusted EBITDA for the third-quarter 2024 increased 9.0% to $146 million compared to $134 million in the third-quarter 2023. Third-quarter 2024 Adjusted Earnings Per Diluted Share (“Adjusted EPS”) increased by $0.01 to $0.17, compared to $0.16 in the third-quarter of 2023.

For the first nine months of 2024, net revenues increased 9.6% to $810 million, compared to $739 million for the same period in 2023. Net revenues increased approximately 9.8% on a constant currency basis.

“I am pleased we achieved both top- and bottom-line growth for the third-quarter,” said Chairman and Chief Executive Officer Michael B. Petras, Jr. “Our performance was largely in line with expectations, with an additional benefit at Nordion tied to the timing of cobalt-60 shipments. With most of the year behind us, we are reaffirming the 2024 revenue and EBITDA outlook ranges previously provided.”

“We are also excited to host our inaugural investor day on November 20th, which will take place in New York City,” Petras continued. “During the event, the management team will present a business and financial review, including future growth plans, while highlighting how we fulfill our mission of Safeguarding Global Health®.”

2024 Outlook

Today, Sotera Health is reaffirming the following 2024 outlook ranges previously provided:

• Net revenues and Adjusted EBITDA growth in the range of 4.0% to 6.0%,
• Interest Expense in the range of $165 million to $175 million,
• Tax rate applicable to Adjusted Net Income⁽³⁾ in the range of 31.5% to 34.5%,
• Adjusted EPS in the range of $0.67 to $0.75,
• A weighted-average fully diluted share count in the range of 283 million to 285 million shares, and

The following range in the 2024 outlook is being updated:

• Capital expenditures are now expected to be in the range of $175 million to $185 million, from previous guidance of $205 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, the impact of inflationary trends including their impact on energy prices and the supply of labor, and the expectation that exchange rates as of September 30, 2024 remain constant for the remainder of 2024. 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.”

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 and Other 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, 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 net of 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.
