Second-Quarter and First-Half 2022 Highlights by Business Segment

Sterigenics

For the second quarter of 2022, Sterigenics net revenues were $158 million, an increase of 8.7% compared to the second quarter a year ago. Second quarter 2022 segment income increased 6.9% to $85 million. For the first six months of 2022, Sterigenics net revenues were $307 million, an increase of 11.2% compared to the same period in 2021. Segment income increased 11.1% to $165 million.

Revenue and segment income growth for the second quarter of 2022 were driven by favorable pricing, volume and mix, partially offset by an unfavorable impact from foreign currency exchange rates. Second quarter 2022 segment income margin decline was driven by a timing of contractual pricing actions versus realized inflation.

Nordion

For the second quarter of 2022, Nordion net revenues were $50 million, an increase of 2.8% compared to the second quarter a year ago. Second quarter 2022 segment income declined 3.8% to $30 million. For the first six months of 2022, Nordion net revenues were $84 million, an increase of 12.6% compared to the same period in 2021. Segment income increased 8.7% to $49 million.

Revenue growth for the second quarter of 2022 was driven by favorable pricing, partially offset by an unfavorable impact from foreign currency exchange rates. Second quarter 2022 segment income and segment income margin decline from second quarter 2021 was driven by less favorable product mix and an unfavorable impact from foreign currency exchange rates.

Nelson Labs

For the second quarter of 2022, Nelson Labs net revenues were $58 million, an increase of 1.3% compared to the second quarter a year ago. Segment income declined 11.6% to $21 million. For the first six months of 2022, Nelson Labs net revenues were $112 million, a decline of 0.9% compared to the same period in 2021. Segment income declined 18.8% to $38 million.

Revenue growth for second quarter 2022 was driven by revenue from recent acquisitions and favorable pricing, partially offset by the decline in pandemic-related testing volumes as well as changes in foreign currency exchange rates. Second quarter 2022 segment income decline was driven by the reduction in demand for pandemic-related testing offset by the incremental contribution of the RCA acquisition and favorable pricing. Segment income margin decline was due to dilution from recent acquisitions and less favorable mix due to a reduction in demand for pandemic-related testing. Second-quarter 2022 margin improved over 400 basis points from first quarter of 2022 as Omicron-related capacity constraints diminished and volume from high-value testing services, other than pandemic-related testing, was favorable.

Balance Sheet and Liquidity

As of June 30, 2022, Sotera Health had $1.80 billion of total debt and $141 million of cash and cash equivalents, compared to $1.79 billion of total debt and $107 million of cash and cash equivalents as of December 31, 2021. The majority of the Company's debt does not mature until 2026. Sotera Health's net leverage ratio as of June 30, 2022 remained stable at 3.4x, within the Company's stated range of 2.0x to 4.0x, and liquidity remains strong. Please refer to the section "Non-GAAP Financial Measures" provided later in this release.

2022 Outlook

Today, Sotera Health is providing an update on its full-year 2022 outlook, which was first provided on March 1, 2022. The Company's new outlook is:

Net revenues in the range of $1.0 to $1.022 billion, from previous guidance of $1.0 to $1.03 billion, representing growth of approximately 7% to 10%, compared to the prior year,
Adjusted EBITDA in the range of $515 to $525 million, from previous guidance of $515 to $535 million, representing growth of approximately 7% to 9%, compared to the prior year,
Tax rate applicable to Adjusted Net Income in the range of 29% to 30%,
Adjusted EPS in the range of $0.93 to $0.97 from previous guidance of $0.93 to $0.99 representing growth of 6% to 10% versus the prior year,
A fully diluted share count in the range of 280 million to 282 million shares on a weighted-average basis,
Capital expenditures in the range of $140 million to $170 million, and
Net leverage reduction of approximately 1⁄2 of a turn.

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 ("Co-60"), the impact of inflationary trends including their impact on energy prices and the supply of labor, the impact of the COVID-19 pandemic including the rate of recoveries of elective procedures and new product development testing, and the expectation that exchange rates as of second-quarter 2022 remain constant for the remainder of 2022. 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 "Forward-Looking Statements."

Forward-Looking Statements

Unless expressly indicated or the context requires otherwise, the terms "Sotera Health," "Company," "we," "us," and "our" in this document refer to Sotera Health Company, a Delaware corporation, and, where appropriate, its subsidiaries on a consolidated basis. This release contains forward-looking statements that reflect management's expectations about future events and the Company's operating plans and performance and speak only as of the date hereof. You can identify these forward-looking statements by the use of forward-looking words such as "will," "may," "plan," "estimate," "project," "believe," "anticipate," "expect," "intend," "should," "would," "could," "target," "goal," "continue to," "positioned to," "are confident" or the negative version of those words or other comparable words. In addition, any statements that refer to expectations, projections or other characterizations of future events or circumstances, are forward-looking statements. Any forward-looking statements contained in this release are based upon our historical performance and on our current plans, estimates and expectations in light of information currently available to us. The inclusion of this forward-looking information should not be regarded as a representation by us that the future plans, estimates or expectations contemplated by us will be achieved. These forward-looking statements are subject to various risks, uncertainties and assumptions relating to our operations, financial results, financial condition, business, prospects, growth strategy and liquidity. These risks and uncertainties include, without limitation, any disruption in the availability or supply, or increases in the price of EO or Co-60, including geopolitical risks related to the supply of Co-60 from Russia; changes in industry trends, environmental, health and safety regulations or preferences; the impact of current and future legal proceedings and liability claims, including litigation related to purported exposure to emissions of EO from our facilities in Illinois, Georgia and New Mexico and the possibility that other claims will be made in the future relating to these or other facilities; our ability to increase capacity at existing facilities, renew leases for our leased facilities and build new facilities in a timely and cost-effective manner; competition for qualified employees in the industries in which we operate; the risks of doing business internationally; and any inability to pursue strategic transactions or find suitable acquisition targets. For additional discussion of these risks and uncertainties, please refer to Company's filings with the SEC, such as its annual 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

The Company does not provide a reconciliation of the forward-looking Adjusted EBITDA, Adjusted Net Income, Adjusted EPS, and Net Leverage Ratio outlook to the most directly comparable GAAP measure, as this cannot be done without unreasonable effort due to the variability and low visibility with respect to certain items, including, among others, uncertainties caused by the global COVID-19 pandemic, changes to the regulatory landscape, restructuring items and certain fair value measurements, all of which are potential adjustments for future earnings. The variability of these items could have a potentially unpredictable, and a potentially significant, impact on our future GAAP results.

To supplement our consolidated financial statements presented in accordance with GAAP, we consider Adjusted EBITDA, Adjusted Net Income, Adjusted EPS, Net Debt and Net Leverage Ratio, 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 and the mark-to-market impact of derivatives not accounted for as hedges, 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, including financing leases, plus unamortized debt issuance costs and debt discounts, less cash and cash equivalents.

Our Net Leverage Ratio is equal to Net Debt divided by the trailing twelve-months of 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 U.S. GAAP.

We use these non-GAAP financial measures as the principal measures of our operating performance. Management believes these are useful because they 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 absent this 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 basis 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.
