Second-Quarter and First-Half 2026 Review by Business Segment
(All comparisons are against second quarter of 2025, unless otherwise noted)

Sterigenics

Sterigenics delivered strong second-quarter 2026 results, with net revenues up 8.6% to $212 million, or 7.0% on a constant currency basis. Segment income improved to $118 million, an increase of 9.6%. For the first six months of 2026, Sterigenics net revenues increased 9.1% to $398 million, or 6.6% on a constant currency basis. Segment income increased 9.6% to $215 million.

Second-quarter net revenues growth was driven by favorable pricing, improved volume/mix and a foreign currency benefit. Segment income and segment income margin also benefited from these factors, partially offset by inflation.

Nordion

Nordion net revenues were up 15.8% to $49 million, or 16.7% on a constant currency basis while segment income increased 19.2% to $28 million. For the first six months of 2026, Nordion net revenues increased 21.6% to $91 million, or 20.8% on a constant currency basis. Segment income increased 26.4% to $52 million.

Second-quarter net revenues growth was driven by improved volume/mix, primarily due to the timing of Cobalt-60 harvests and favorable pricing, partially offset by foreign currency. Segment income and segment income margin also benefited from these factors, partially offset by inflation.

Nelson Labs

Nelson Labs delivered strong second-quarter net revenues growth of 6.3% to $61 million, or 5.4% on a constant currency basis. Segment income improved to $20 million, an increase of 0.6%. For the first six months of 2026, Nelson Labs net revenues improved 2.9% to $113 million, or 0.9% on a constant currency basis, while segment income decreased 4.9% to $34 million.

Second-quarter net revenues and segment income growth were driven by favorable pricing, improved volume/mix and a foreign currency benefit. Segment income margin was impacted by higher costs.

Balance Sheet and Liquidity

As of June 30, 2026, Sotera Health had $2.2 billion of total debt, and $357 million in unrestricted cash and cash equivalents, compared to $2.2 billion in total debt and $345 million in unrestricted cash and cash equivalents as of December 31, 2025. Sotera Health’s Net Leverage Ratio as of June 30, 2026 improved to 3.0x, achieving the Company’s long-term net leverage ratio target range of 2.0x to 3.0x. As of June 30, 2026, available liquidity increased to approximately $950 million, and the Company had no outstanding borrowings under its $600 million revolving credit facility.

Full-Year 2026 Outlook

Today, Sotera Health is raising its 2026 outlook:

• Net revenues range raised to $1.236 billion to $1.254 billion, representing constant currency growth of 5.25% to 6.75% and an estimated 100 basis points of foreign currency benefit
• Adjusted EBITDA range raised to $634 million to $643 million, representing constant currency growth of 5.75% to 7.25% and an estimated 100 basis points of foreign currency benefit
• Interest expense improved to a range of $135 million to $142 million
• Tax rate applicable to Adjusted Net Income⁽²⁾ improved to a range of 27.0% to 28.0%
• Adjusted EPS improved to a range of $0.95 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 $200 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, 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 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.”

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 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.
• 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.
