Adjusted income from operations1 was $84.5 million, compared to $90.6 million in the fourth quarter of 2022. Adjusted diluted earnings per share1 was $0.54, compared to $0.60 in the fourth quarter of 2022. Cash flow from operations for the year ended December 31, 2023 was $243.3 million, compared to $200.2 million in 2022.

KEY BUSINESS HIGHLIGHTS:

•Grew Regulated Waste and Compliance Services (“RWCS”) organic revenues1 3.1% compared to the fourth quarter of 2022.

•Improved gross profit 150 basis points compared to the fourth quarter of 2022.

•Acquired a U.S. regulated waste tuck-in business in January 2024.

•Continued to implement workforce management actions in the first quarter of 2024, which are expected to generate over $35 million in cost savings in 2024.

“Throughout 2023, we made strong progress executing across all of our key business priorities, most notably the ERP deployment for our U.S. Regulated Waste and Compliance Services business and portfolio optimization, as we completed eight divestitures in the year. 2023 organic revenue and Adjusted EPS(3) performance came in line with our expectations. We continued to drive efficiency improvements in cost of revenues that helped mitigate headwinds of approximately $50 million in commodity indexed revenues in 2023,” said Cindy J. Miller, President and Chief Executive Officer. “We look forward to building on the strength of the foundation we have established, leveraging our next generation of key business priorities to drive growth. We plan to harness a streamlined workforce, modern technology, updated facilities, and a refreshed fleet, which we expect will drive growth in top line and profitability.”

FOURTH QUARTER FINANCIAL RESULTS

U.S. Generally Accepted Accounting Principles (GAAP) Results

•Revenues in the fourth quarter were $652.0 million compared to $670.4 million in the fourth quarter of 2022. The decrease was primarily due to divestitures of $28.6 million, which was partially offset by favorable foreign exchange rates of $5.0 million. Organic revenues grew $5.2 million, with RWCS growing $13.2 million and Secure Information Destruction (“SID”) organic revenues declining $8.0 million. The decline in SID was mainly a result of lower SID commodity indexed revenues due to lower recycling revenue and lower fuel and environmental surcharges of $18.0 million.

•Income from operations in the fourth quarter was $37.1 million compared to $59.1 million in the fourth quarter of 2022. The $22.0 million decrease was mainly due to a gain on divestitures in 2022 of $15.6 million; lower SID commodity indexed revenue margin flow-through of $10.2 million; higher bad debt expense of $8.1 million, primarily due to a lower fourth quarter of 2022 bad debt expense level as a result of improved North America SID collections; and higher incentive and stock based compensation of $7.1 million. These were partially offset by margin flow-through of $18.9 million, including cost savings from productivity initiatives.

•Net income in the fourth quarter was $14.9 million, or $0.16 diluted earnings per share, compared to $31.8 million, or $0.35 in the fourth quarter of 2022. The decrease was primarily attributable to lower Income from operations of $22.0 million, as explained above.

•Cash flow from operations for the year ended December 31, 2023, was $243.3 million, compared to $200.2 million in 2022. The year-over-year increase of $43.1 million was primarily driven by lower FCPA4 settlement payments of $72.8 million and lower annual incentive compensation payments of $22.3 million, partially offset by increased accounts receivable, net of deferred revenues of $68.5 million.

•Cash paid for capital expenditures for the year ended December 31, 2023 was $131.3 million, compared to $132.2 million in 2022.

Non-GAAP Results

•For the fourth quarter of 2023, organic revenues1 increased 0.9%, which excludes the impacts of divestitures and foreign exchange rates. RWCS organic revenues1 increased 3.1% while SID organic revenues1 decreased 3.6%, mainly due to lower SID commodity indexed revenues, as explained above.

•Adjusted income from operations1 was $84.5 million compared to $90.6 million in the fourth quarter of 2022. As a percentage of revenues, the 50 basis points decrease was mainly due to lower commodity indexed revenue margin flow-through of 160 basis points; higher bad debt expense of 120 basis points, as explained above; and higher incentive and stock based compensation of 110 basis points. These were partially offset by margin flow-through of 340 basis points, including cost savings and portfolio optimization.

•Adjusted diluted earnings per share1 was $0.54, compared to $0.60 in the fourth quarter of 2022. The $0.06 decrease was mainly driven by lower SID commodity indexed revenue margin flow-through of $0.09; higher bad debt expense of $0.07, as explained above, and higher incentive compensation of $0.06. These were partially offset by margin flow-through of $0.16.

•Free cash flow2 for the year ended December 31, 2023 was $112.0 million, compared to $68.0 million in 2022. The $44.0 million increase was primarily due to higher cash flow from operations of $43.1 million, as explained above.

When we use words such as “believes”, “expects”, “anticipates”, “estimates”, “may”, “plan”, “will”, “goal”, or similar expressions, we are making forward-looking statements. Forward-looking statements are prospective in nature and are not based on historical facts, but rather on current expectations and projections of our management about future events and are therefore subject to risks and uncertainties, which could cause actual results to differ materially from the future results expressed or implied by the forward-looking statements. Factors that could cause such differences include, among others, inflationary cost pressure in labor, supply chain, energy, and other expenses, decreases in the volume of regulated wastes or personal and confidential information collected from customers, and disruptions resulting from deployment of systems, disruptions in our supply chain, disruptions in or attacks on data information technology systems, labor shortages, a recession or economic disruption in the U.S. and other countries, changing market conditions in the healthcare industry, competition and demand for services in the regulated waste and secure information destruction industries, SOP (Sorted Office Paper) pricing volatility or pricing volatility in other commodities, changes in the volume of paper processed by our secure information destruction business and the revenue generated from the sale of SOP, foreign exchange rate volatility in the jurisdictions in which we operate, changes in governmental regulation of the collection, transportation, treatment and disposal of regulated waste or the proper handling and protection of personal and confidential information, the level of government enforcement of regulations governing regulated waste collection and treatment or the proper handling and protection of personal and confidential information, the outcome of pending, future or settled litigation or investigations, charges related to portfolio optimization or the failure of acquisitions or divestitures to achieve the desired results, the obligations to service substantial indebtedness and comply with the covenants and restrictions contained in our credit agreements and Senior Notes, rising interest rates or a downgrade in our credit rating resulting in an increase in interest expense, political, economic, war, and other risks related to our foreign operations, pandemics and the resulting impact on the results of operations, long-term remote work arrangements which may adversely affect our business, restrictions on the ability of our team members to travel, closures of our facilities or the facilities of our customers and suppliers, weather and environmental changes related to climate change, requirements of customers and investors for net carbon zero emissions strategies, and the introduction of regulations for greenhouse gases, which could negatively affect our costs to operate, failure to maintain an effective system of internal control over financial reporting, as well as other factors described in our filings with the SEC, including the 2023 Form 10-K and subsequent Quarterly Reports on Form 10-Q.

(1)Components of Change (%) in summation may not crossfoot to the total Change (%) due to rounding.

(2)Organic growth is the change in revenues which includes SOP (sorted office paper) pricing and volume and excludes the impact of an acquisition, divestitures, and foreign exchange.

(3)The comparisons at constant currency rates (foreign exchange) reflect comparative local currency balances at prior period’s foreign exchange rates. Stericycle calculated these percentages by taking current period reported Revenues less the respective prior period reported Revenues, divided by the prior period reported Revenues, all at the respective prior period’s foreign exchange rates. This measure provides information on the change in Revenues assuming that foreign currency exchange rates have not changed between the prior and the current period.

a.The Non-GAAP financial measures contained in this press release are reconciled to the most comparable measures calculated in accordance with U.S. GAAP in the schedules attached to this release. Management believes the Non-GAAP financial measures are useful measures of Stericycle’s performance because they provide additional information about Stericycle’s operations and exclude certain adjusting items, allowing better evaluation of underlying business performance and better period-to-period comparability. The Non-GAAP financial measures contained in this press release may not be calculated in the same manner as certain other Non-GAAP financial measures and are used solely to evaluate management’s performance for incentive compensation purposes. All Non-GAAP financial measures are intended to supplement the applicable U.S. GAAP measures and should not be considered in isolation from, or a replacement for, financial measures prepared in accordance with U.S. GAAP and may not be comparable to or calculated in the same manner as Non-GAAP financial measures published by other companies.

b.Adjusted Earnings Before Interest, Tax, Depreciation and Amortization (Adjusted EBITDA) is Income from operations excluding certain adjusting items, depreciation and intangible amortization.

c.Under the Net Income (Loss) Attributable to Common Shareholders column, adjustments are shown net of tax in aggregate of $12.4 million and $7.8 million for the three months ended December 31, 2023 and 2022, respectively, based on applying the statutory tax rate for the jurisdictions in which the adjustment occurred or, by adjusting the tax effect to consider the impact of applying an annual effective tax rate on an interim basis. For purposes of reconciling adjusted diluted earnings per share with respect to taxes period-over-period, the company utilizes a “rate approach” to highlight the impact of the adjusted tax rate. It is computed by multiplying the prior period adjusted rate by the current period adjusted income before taxes to determine the expected tax expense. Such expected tax expense is then compared to actual tax expense. Expected tax in excess of actual tax variance is favorable; actual tax in excess of expected tax variance is unfavorable. The variance divided by diluted shares outstanding at the end of the period yields the impact on earnings per share. Management believes the use of this measure best aids in explaining the impact of a changing tax rate.
