(1) This is a non-GAAP financial measure used throughout this press release; please refer to the section “Non-GAAP Financial Measures” for explanations of our non-GAAP financial measures and the schedules provided later in this release for reconciliations of reported GAAP to non-GAAP financial measures.1

Sterigenics delivered strong third-quarter 2026 results, with net revenues up 8.5% to $209 million, or 8.2% on a constant currency basis. Segment income improved to $117 million, an increase of 9.6%. For the first nine months of 2026, Sterigenics net revenues increased 8.9% to $607 million, or 7.2% on a constant currency basis, compared to the same period in 2025. Segment income increased 9.6% to $332 million.

Net revenues growth for the third quarter was driven by pricing, improved volume and mix, and a foreign currency benefit. Segment income and segment income margin also benefited from these factors, partially offset by inflation.

Nordion net revenues were $55 million for the third-quarter 2026, a decrease of 12.4%, or 11.5% on a constant currency basis, due to the expected year-over-year impact of Co-60 harvest schedules. Correspondingly, segment income decreased 11.4% to $34 million. For the first nine months of 2026, Nordion net revenues increased 6.1% to $146 million, or 6.2% on a constant currency basis, compared to the same period in 2025. Segment income increased 8.2% to $85 million.

The change in third-quarter net revenues and segment income for the quarter was driven by unfavorable volume and mix due to the expected timing of Co-60 harvest schedules and foreign exchange, partially offset by favorable pricing. Segment income margin improved, driven by operational productivity and favorable pricing, partially offset by inflation.

Nelson Labs delivered strong third-quarter 2026 net revenues growth of 8.8% to $61 million, or 9.2% on a constant currency basis. Nelson Labs third-quarter 2026 segment income increased 2.5% to $19 million. For the first nine months of 2026, Nelson Labs net revenues increased 4.9% to $173 million, or 3.7% on a constant currency basis, compared to the same period in 2025. Segment income decreased 2.4% to $54 million.

Net revenues and segment income growth for the third quarter were driven by favorable volume and mix as well as pricing, partially offset by foreign exchange. Segment income margin was impacted primarily by business mix.

As of September 30, 2026, Sotera Health had $2.2 billion of total debt and $412 million in unrestricted cash and cash equivalents, compared to $2.2 billion in total debt and $345 million of unrestricted cash and cash equivalents as of December 31, 2025.

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, Tax Rate Applicable to Adjusted Net Income, 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 Co-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.”

(2)This is a non-GAAP financial measure used throughout this press release; please refer to the section “Non-GAAP Financial Measures” for explanations of our Non-GAAP financial measures and the schedules provided later in this release for reconciliations of reported GAAP to Non-GAAP financial measures.

To supplement our consolidated financial statements presented in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”), we consider Adjusted EBITDA, Adjusted EBITDA margin, Tax Rate Applicable to Adjusted Net Income, Adjusted Net Income, Adjusted EPS, Net Debt, Net Leverage Ratio and constant currency, each of which is a financial measure 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, 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.

• Tax Rate Applicable to Adjusted Net Income represents the difference between the income tax provision as determined under U.S. GAAP and the income tax benefit/provision associated with pre-tax adjustments used to calculate Adjusted Net Income.

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.
