Segment income growth for the quarter was driven by favorable pricing and changes in volume and mix, partially offset by inflation and unfavorable changes in foreign currency rates.

Nordion

For fourth-quarter 2024, Nordion net revenues were $57 million, a decrease of 28.9%, compared to the fourth quarter a year ago, as expected, due to the timing of cobalt harvest schedules. Nordion net revenues declined 26.8% on a constant currency basis. Segment income decreased 33.8% to $35 million.

The timing of Co-60 supply harvest schedules resulted in unfavorable volume and mix, which was the primary driver for net revenue, segment income and segment income margin declines for fourth-quarter 2024, partially offset by favorable pricing. Unfavorable changes in foreign currency exchange rates also contributed to the declines in revenue and segment income.

Nelson Labs

For fourth-quarter 2024, Nelson Labs net revenues were $54 million, a decrease of 7.3% compared to the fourth quarter a year ago. Nelson Labs net revenues declined 7.0% on a constant currency basis. Segment income decreased 3.3% to $18 million.

Segment income decline for the fourth-quarter 2024 was driven by unfavorable volume and mix as well as higher employee compensation costs, partially offset by favorable pricing and labor productivity. Segment income margin improved primarily due to lower Expert Advisory Services revenue, favorable pricing and labor productivity.

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 average exchange rates for January 2025 remain constant for the remainder of 2025. 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."

⁽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.

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 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 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.
