On a GAAP basis, the third quarter of 2026 diluted earnings per share from continuing operations was $0.16, including restructuring costs in Harsco Environmental, a gain related to the initial payment received from GBM for project-related assets following Rail's Deutsche Bahn contract exit, a favorable adjustment to the exit reserve for the Deutsche Bahn contract due to the release of performance bonds, and additional expenses related to the sale of Clean Earth and spin-off of Harsco Environmental and Harsco Rail. The adjusted diluted loss per share from continuing operations in the third quarter of 2026 was $0.16. These figures compare with a third quarter 2025 GAAP diluted loss per share from continuing operations of $0.82, which included strategic expenses and restructuring costs, and an adjusted diluted loss per share from continuing operations of $0.59.

The GAAP consolidated earnings from continuing operations for the third quarter of 2026 was $6 million, while Adjusted EBITDA excluding unusual items totaled $47 million in the quarter.

“We experienced continued momentum across both of our businesses in the third quarter, with Enviri delivering adjusted earnings growth of more than 20% for the second consecutive quarter and achieving better than anticipated results,” said Enviri President and CEO Russell Hochman. “Both businesses, in fact, reported their highest quarterly earnings in approximately two years, with this performance supported by strong operational execution. Based on these results, we have raised our full-year Adjusted EBITDA outlook.”

“In the third quarter, we completed the final assessment phase of our internal improvement program,” continued Hochman. “Based on our assessment, we expect to deliver approximately $40 million in earnings growth over the next two years through actions already underway and additional measures planned for the coming quarters as part of the program. These initiatives are designed to improve underlying performance across market cycles, while positioning the Company to deliver additional upside in healthier demand environments. Together, we believe these actions provide a strong foundation for sustainable earnings growth, cash flow generation and long-term shareholder value creation.”

Third Quarter Business Review

Harsco Environmental

                                                3

Harsco Environmental revenues totaled $273 million in the third quarter of 2026, an increase of 5% compared with the prior-year quarter. This revenue increase is attributable to higher volumes and services pricing. The segment's GAAP operating income was $20 million, and Adjusted EBITDA totaled $50 million in the third quarter of 2026. These figures compare with GAAP operating income of $13 million and Adjusted EBITDA of $44 million in the prior-year period. The year-on-year change in adjusted earnings reflects the above-mentioned factors as well as internal improvement actions. As a result, Harsco Environmental's Adjusted EBITDA margin increased to 18.2% in the third quarter of 2026 versus 17.0% in the comparable quarter of 2025.

Harsco Rail

Harsco Rail revenues in the third quarter of 2026 totaled $52 million. The change in revenues compared with the prior-year period is attributable to lower volumes, including equipment volumes as a result of Rail exiting its contracts with Network Rail and Deutsche Bahn. The segment's GAAP operating income was $19 million, and Adjusted EBITDA was $1 million in the third quarter of 2026. These figures compare with a GAAP operating loss of $9 million and an Adjusted EBITDA loss of $4 million in the prior-year period. The year-on-year change in adjusted earnings is attributable to lower operating costs (including the impact of lower cost of sales using LIFO) and a more favorable business mix.

Cash Flow

Net cash used by operating activities was $7 million in the third quarter of 2026, compared with net cash provided by operating activities of $34 million in the prior-year period. Adjusted free cash flow was $(18) million in the third quarter of 2026, compared with $(41) million in the prior-year period (excluding Clean Earth and any transaction-related expenditures). The change in adjusted free cash flow compared with the prior-year quarter is attributable to lower working capital in Harsco Rail (including the impact of exiting two ETO contracts) and lower financing costs, partially offset by working capital timing in Harsco Environmental.

                                                4

2026 Outlook

The Company has increased its Adjusted EBITDA outlook for Harsco Environmental and Rail, reflecting higher volume expectations (including for services in HE and aftermarket in Rail) as well as business improvements. These improvements include cost benefits from structural cost optimization and productivity initiatives implemented in recent months. Key business drivers for each segment in 2026 are as follows:

Harsco Environmental Adjusted EBITDA of $180 million to $184 million, which is above prior-year results. Higher demand for services and products, along with new sites and improvement initiatives, are expected to be partially offset by site exits and certain 2025 items that are not anticipated to repeat in 2026, such as the recovery of certain sales tax expenses in Brazil.

Harsco Rail Adjusted EBITDA of $(7) million to $(10) million, which is above 2025 as a result of higher aftermarket contributions as well as cost optimization and productivity initiatives, partially offset by lower standard equipment and contracted services demand.

Non-GAAP Measures

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 (loss) 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 (loss) 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); stock-based compensation 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 (which is adjusted for all stock-based compensation expense) 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.

Adjusted free cash flow: Adjusted 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. Adjusted free cash flow also excludes the impact of the Clean Earth business. The Company's management believes that Adjusted free cash flow is important to management and useful to investors as a supplemental measure as it indicates the cash flow available for working capital needs, repay debt obligations, invest in future growth through new business development activities, conduct strategic acquisitions or other uses of cash. It is important to note that Adjusted 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. This presentation provides a basis for comparison of ongoing operations and prospects.
