CLEVELAND, Aug. 05, 2024 (GLOBE NEWSWIRE) — Sotera Health Company (“Sotera Health” or the “Company”) (Nasdaq: SHC), a leading global provider of mission-critical end-to-end sterilization solutions, lab testing and advisory services for the healthcare industry, today announced financial results for the three and six months ended June 30, 2024.

Second-quarter 2024 net revenues increased 8.3% to $277 million, compared to $255 million in the second-quarter 2023. Net revenues increased 8.8% on a constant currency basis. Net income was $9 million, or $0.03 per diluted share, compared to net income of $24 million, or $0.08 per diluted share in the second-quarter of 2023. The net income decline was primarily driven by customary charges associated with the successful refinancing of both of the Company’s term loans. Adjusted EBITDA for the second-quarter 2024 increased 6.9% to $137 million compared to $128 million in the second-quarter 2023. Second-quarter 2024 Adjusted Earnings Per Diluted Share (“Adjusted EPS”) of $0.19 declined $0.01 compared to $0.20 in the second quarter of 2023 driven by higher interest expense.

For the first six months of 2024, net revenues increased 10.3% to $525 million, compared to $476 million for the same period in 2023. Net revenues increased approximately 10.2% on a constant currency basis. Net income was $15 million, or $0.05 per diluted share for the first half of 2024, compared to net income of $26 million, or $0.09 per diluted share, for the same period last year. Adjusted EBITDA for the first half of 2024 increased 9.8% to $249 million and Adjusted EPS decreased by $0.01 to $0.32 compared to the first half of 2023.

“We are pleased to have achieved both revenue and Adjusted EBITDA growth for the second quarter with all three business segments reporting volume increases,” said Chairman and Chief Executive Officer, Michael B. Petras, Jr. “With the first half of the year completed and as the market continues to slowly stabilize, we are reaffirming our 2024 outlook.”

Second-Quarter and First-Half 2024 Review by Business Segment

Sterigenics

For second-quarter 2024, Sterigenics net revenues were $176 million, an increase of 5.9% compared to the second quarter a year ago. Second-quarter 2024 segment income was $97 million, an increase of 5.8%. For the first six months of 2024, Sterigenics net revenues were $343 million, an increase of 5.0% compared to the same period in 2023. Segment income increased 4.8% to $183 million.

Net revenue growth for the second-quarter 2024 was driven by favorable pricing as well as volume and changes in mix, partially offset by unfavorable changes in foreign currency exchange rates.

The increase in segment income for the second-quarter 2024 was driven by favorable pricing as well as volume and changes in mix, partially offset by inflation.

Nordion

For second-quarter 2024, Nordion net revenues were $41 million, an increase of 29.0% compared to the second quarter a year ago. Second-quarter 2024 segment income increased 31.7% to $23 million. For the first six months of 2024, Nordion net revenues were $65 million, an increase of 61.0% compared to the same period in 2023. Segment income increased 77.1% to $34 million.

The timing of reactor harvest schedules resulted in the favorable volume and mix increase at Nordion, which was a primary driver for net revenue, segment income and segment income margin growth for the quarter. Favorable pricing also drove improvement, partially offset by unfavorable changes in foreign currency exchange rates.

Nelson Labs

For the second-quarter 2024, Nelson Labs net revenues were $59 million, an increase of 4.0% compared to the second quarter a year ago. Second-quarter 2024 segment income decreased by 11.0% to $17 million. For the first six months of 2024, Nelson Labs net revenues were $117 million, an increase of 7.3% compared to the same period in 2023. Segment income declined 2.6% to $32 million.

Net revenue growth for the second-quarter 2024 was driven by favorable pricing as well as volume and changes in mix, partially offset by unfavorable changes in foreign currency exchange rates.

Segment income and segment income margin declines for the second-quarter 2024 were primarily due to the impacts of volume and mix, as well as higher labor costs, partially offset by favorable pricing.

Balance Sheet and Liquidity

As of June 30, 2024, Sotera Health had $2.3 billion of total debt, and $246 million in unrestricted cash and cash equivalents, compared to $2.3 billion in total debt and $296 million in unrestricted cash and cash equivalents as of December 31, 2023. As of June 30, 2024 the Company had no balance outstanding on its revolving credit facility. Sotera Health’s Net Leverage Ratio⁽²⁾ as of June 30, 2024 was 3.8x.

On May 30, 2024, the Company refinanced its existing term loans totaling $2.3 billion maturing in December of 2026 with a $1.5 billion term loan maturing on May 30, 2031 and $750.0 million of 7.375% senior secured notes maturing on June 1, 2031.

2024 Outlook

Today, Sotera Health is reaffirming the 2024 outlook previously provided. As a reminder, the outlook is:

• 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
• Capital expenditures in the range 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 the impact on energy prices and the supply of labor, and the expectation that exchange rates as of June 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.”

Non-GAAP 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, 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 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.
