PHILADELPHIA (February 29, 2024) - Enviri Corporation (NYSE: NVRI) today reported fourth quarter 2023 results. On a U.S. GAAP ("GAAP") basis, the fourth quarter of 2023 diluted loss per share from continuing operations was $0.17, after strategic expenses and other unusual items. The adjusted diluted loss per share from continuing operations in the fourth quarter of 2023 was $0.07. These figures compare with fourth quarter of 2022 GAAP diluted loss per share from continuing operations of $0.30 (including a $15 million intangible asset impairment within Harsco Environmental) and adjusted diluted earnings per share from continuing operations of $0.01.

GAAP operating income from continuing operations for the fourth quarter of 2023 was $28 million. Adjusted EBITDA was $73 million in the quarter, compared to the Company's previously provided guidance range of $62 million to $69 million.

“Enviri had a strong 2023, finishing the year with solid quarterly results and significant momentum in both Clean Earth and Harsco Environmental,” said Enviri Chairman and CEO Nick Grasberger. “Our results benefited from healthy end-market demand and continuing operational excellence across our businesses. The earnings growth in both the quarter and full year was supported by efficiency and growth initiatives and pricing actions implemented across the Company. I would like to thank our employees for their continued commitment to our customers and our company.”

“Looking forward, we expect to maintain our strong business momentum and that our operating results will improve further in 2024, with Clean Earth again leading the way. We also expect to further improve our debt leverage position in 2024. In addition, we are pleased to see improving financial and operating trends in Rail and our efforts to strengthen and sell the business remain ongoing. We remain optimistic about Enviri’s growth potential and the value within each of our businesses, and we will continue to deliver on our strategic priorities to create value for shareholders in the coming years.”

Consolidated revenues from continuing operations were $529 million, an increase of 13 percent compared with the prior-year quarter. Both Clean Earth and Harsco Environmental realized an increase in revenues compared to the fourth quarter of 2022 due to higher services demand and pricing. Foreign currency translation positively impacted fourth quarter 2023 revenues by approximately $4 million, compared with the prior-year period.

The Company's GAAP operating income from continuing operations was $28 million for the fourth quarter of 2023, compared with GAAP operating income of $2 million in the same quarter of 2022. Meanwhile, adjusted EBITDA totaled $73 million in the fourth quarter of 2023 versus $61 million in the fourth quarter of the prior year. Both Harsco Environmental and Clean Earth achieved higher adjusted EBITDA versus the comparable quarter of 2022.

Consolidated revenues from continuing operations were $2.07 billion in 2023, compared to $1.89 billion in 2022. The revenues increase for the year is again attributable to higher volumes and pricing in both the Clean Earth and Harsco Environmental segments. Foreign currency translation negatively impacted 2023 revenues by approximately $8 million compared with the prior year.

GAAP operating income from continuing operations was $111 million in 2023, while the GAAP operating loss from continuing operations in 2022 was $57 million. Adjusted EBITDA was $293 million and $229 million for these years, respectively, with the change in adjusted results reflecting the above-mentioned items that favorably impacted revenues along with various growth and improvement initiatives across the Company.

On a GAAP basis, the diluted loss per share from continuing operations in 2023 was $0.57, and this figure compares with a diluted loss per share in 2022 of $1.73. These figures include various unusual items in each year (including a Clean Earth non-cash goodwill impairment charge of $105 million in 2022). The adjusted diluted loss per share from continuing operations was $0.12 in 2023, compared with adjusted diluted earnings per share from continuing operations of $0.10 in 2022.

Harsco Environmental revenues totaled $292 million in the fourth quarter of 2023, an increase of 14 percent compared with the prior-year quarter. This increase is attributable to higher services and products demand and price increases. The segment's GAAP operating income and adjusted EBITDA totaled $25 million and $56 million, respectively, in the fourth quarter of 2023. These figures compare with a GAAP operating loss of $4 million and adjusted EBITDA of $43 million in the prior-year period. The year-on-year change in adjusted earnings reflects the impact of higher demand, including the impact of new services contracts, and higher prices. As a result, Harsco Environmental's adjusted EBITDA margin increased to 19.3 percent in the fourth quarter of 2023 versus 16.7 percent in the comparable quarter of 2022.

Clean Earth revenues totaled $237 million in the fourth quarter of 2023, a 12 percent increase over the prior-year quarter as a result of higher services pricing and increased demand. The segment's GAAP operating income was $16 million and adjusted EBITDA was $29 million in the fourth quarter of 2023. These figures compare with GAAP operating income of $14 million and adjusted EBITDA of $25 million in the prior-year period. The year-on-year improvement in adjusted earnings reflects the above-mentioned factors and efficiency initiatives, partially offset by higher incentive compensation, severance and other investments.

As a result, Clean Earth's adjusted EBITDA margin increased to 12.2 percent in the fourth quarter of 2023 versus 11.6 percent in the comparable quarter of 2022.

Net cash provided by operating activities was $68 million in the fourth quarter of 2023, compared with net cash provided by operating activities of $19 million in the prior-year period. Free cash flow (excluding Rail) was $25 million in the fourth quarter of 2023, compared with $3 million in the prior-year period. The change in free cash flow compared with the prior-year quarter is attributable to higher cash earnings and working capital improvements.

For the full-year 2023, net cash provided by operating activities totaled $114 million, compared with net cash provided by operating activities of $151 million in 2022. Free cash flow (excluding Rail) was $24 million in 2023, compared with $75 million in the prior year. The change in full-year free cash flow can be attributed to the Company's accounts receivable securitization program implemented in 2022 as well as higher cash interest payments and net capital spending, partially offset by a higher cash earnings from improved business performance and favorable changes in working capital in 2023 from the Company's continuing operations.

The Company's 2024 guidance anticipates that it will again realize an improvement in financial performance compared with 2023. Clean Earth and Harsco Environmental are both expected to contribute to the growth. This outlook contemplates that economic conditions will remain stable and that the Company will benefit from incremental growth and improvement initiatives. Key business drivers for each segment as well as other 2024 guidance details are as follows:

Harsco Environmental adjusted EBITDA is projected to be modestly above prior-year results. Higher services volumes and pricing, site improvement initiatives and new contracts are expected to be partially offset by lower commodities and certain product volumes as well as personnel investments.

Clean Earth adjusted EBITDA is expected to increase versus 2023 as a result of higher services pricing (net of inflation), efficiency initiatives and higher volumes, offsetting the impacts of a less favorable project-related business mix as well as certain other 2023 items not repeating (Stericycle settlement).

Corporate spending is anticipated to be comparable with 2023.

Measurements of financial performance not calculated in accordance with GAAP should be considered as supplements to, and not substitutes for, performance measurements calculated or derived in accordance with GAAP. Any such measures are not necessarily comparable to other similarly-titled measurements employed by other companies. The most comparable GAAP measures are included within the definitions below and reconciliations of these non-GAAP measures to the most directly comparable GAAP financial measures are included at the end of this press release.

Adjusted diluted earnings per share from continuing operations: Adjusted diluted earnings (loss) per share from continuing operations is a non-GAAP financial measure and consists of diluted earnings (loss) per share from continuing operations adjusted for unusual items and acquisition-related intangible asset amortization expense. It is important to note that such intangible assets contribute to revenue generation and that intangible asset amortization related to past acquisitions will recur in future periods until such intangible assets have been fully amortized. The Company’s management believes Adjusted diluted earnings per share from continuing operations is useful to investors because it provides an overall understanding of the Company’s historical and future prospects. Exclusion of unusual items permits evaluation and comparison of results for the Company’s core business operations, and it is on this basis that management internally assesses the Company’s performance. Exclusion of acquisition-related intangible asset amortization expense, the amount of which can vary by the timing, size and nature of the Company’s acquisitions, facilitates more consistent internal comparisons of operating results over time between the Company’s newly acquired and long-held businesses, and comparisons with both acquisitive and non-acquisitive peer companies.

Adjusted EBITDA: Adjusted EBITDA is a non-GAAP financial measure and consists of income (loss) from continuing operations adjusted to add back income tax expense; equity income of unconsolidated entities, net; net interest expense; defined benefit pension income (expense); facility fees and debt-related income (expense); and depreciation and amortization (excluding amortization of deferred financing costs); and excludes unusual items. Segment Adjusted EBITDA consists of operating income from continuing operations adjusted to exclude unusual items and add back depreciation and amortization (excluding amortization of deferred financing costs). The sum of the Segments’ Adjusted EBITDA and Corporate Adjusted EBITDA equals consolidated Adjusted EBITDA. The Company‘s management believes Adjusted EBITDA is meaningful to investors because management reviews Adjusted EBITDA in assessing and evaluating performance.

Free cash flow: Free cash flow is a non-GAAP financial measure and consists of net cash provided (used) by operating activities less capital expenditures and expenditures for intangible assets; and plus capital expenditures for strategic ventures, total proceeds from sales of assets and certain transaction-related / debt-refinancing expenditures. The Company's management believes that Free cash flow is meaningful to investors because management reviews Free cash flow for planning and performance evaluation purposes. It is important to note that Free cash flow does not represent the total residual cash flow available for discretionary expenditures since other non-discretionary expenditures, such as mandatory debt service requirements and settlements of foreign currency forward exchange contracts, are not deducted from this measure. Free cash flow excludes the former Harsco Rail Segment since the segment is reported as discontinued operations. This presentation provides a basis for comparison of ongoing operations and prospects.
