"The Company delivered strong results in 2025, driven by solid execution, increased demand for our mission-critical services, and disciplined financial management," said Michael B. Petras, Jr., Chairman and Chief Executive Officer. "Sterigenics and Nordion delivered strong performance, each achieving high-single digit revenue growth for the year. Nelson Labs delivered growth in core lab testing, while disciplined operational execution drove meaningful margin improvement.

Petras continued, "As we enter 2026, we are encouraged by our momentum and strengthened balance sheet, and we are confident in our ability to drive long-term growth, strong free cash flow, and shareholder value as we remain on track to meet the financial goals presented at our November 2024 investor day."

Fourth-Quarter and Full-Year 2025 Review by Business Segment

Sterigenics

Sterigenics delivered strong fourth-quarter 2025 results, with net revenues up 10.6% to $198 million, or 8.0% on a constant currency basis, compared to the fourth-quarter of 2024. Segment income was $110 million, a double-digit increase of 10.4%.

The growth in fourth quarter net revenues and segment income was driven by favorable pricing, volume/mix and changes in foreign currency exchange rates, with segment income growth partially offset by inflation.

Sterigenics delivered strong full-year 2025 performance, with net revenues up 8.3% to $756 million, or 7.7% on a constant currency basis, compared to 2024. Segment income grew 9.2% to $413 million, reflecting strong operating performance.

Nordion

Nordion fourth-quarter 2025 net revenues were $50 million, an expected decrease of 12.3%, or 12.6% on a constant currency basis, due to the timing of cobalt-60 harvest schedules, compared to the fourth quarter 2024. Segment income decreased 18.9% to $29 million.

The change in fourth quarter net revenues and segment income was primarily driven by unfavorable volume/mix due to the timing of cobalt-60 harvest schedules, partially offset by favorable pricing. Segment income margin was also impacted by unfavorable product mix.

Nordion delivered strong full-year 2025 performance, with net revenues up 8.2% to $188 million, or 9.1% on a constant currency basis, compared to 2024. Segment income increased by 6.3% to $108 million.

Nelson Labs

Nelson Labs fourth-quarter 2025 net revenues increased 2.3% to $55 million, or a 0.2% decrease on a constant currency basis, compared to the fourth-quarter 2024. Segment income increased 1.9% to $18 million.

The increase in fourth quarter net revenues and segment income was driven by favorable pricing, improvement in core lab testing services and changes in foreign currency exchange rates, partially offset by a decline in Expert Advisory Services. Segment income growth was also partially offset by higher costs.

Nelson Labs full-year 2025 net revenues decreased 3.9% to $220 million, or 5.0% on a constant currency basis, compared to 2024. Segment income increased 6.0% to $73 million.

Balance Sheet and Liquidity

As of December 31, 2025, Sotera Health had $2.2 billion in total debt, and $345 million in cash and cash equivalents, compared to $2.3 billion in total debt and $277 million in cash and cash equivalents as of December 31, 2024. Sotera Health's Net Leverage Ratio⁽¹⁾ as of December 31, 2025 improved to 3.2x, compared to 3.7x as of December 31, 2024. The Company had no outstanding borrowings on its revolving credit facility as of December 31, 2025.

In 2025, Warburg Pincus LLC and GTCR, LLC completed three secondary share sales increasing public float to 80% of outstanding shares. These transactions did not impact the company's liquidity or net leverage metrics.

• 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."

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.
