Exhibit 99.1 FOR IMMEDIATE RELEASE CASELLA WASTE SYSTEMS, INC. ANNOUNCES SECOND QUARTER 2025 RESULTS RUTLAND, VERMONT (July 31, 2025) — Casella Waste Systems, Inc. (NASDAQ: CWST), a regional solid waste, recycling and resource management services company, today reported its financial results for the three and six-month periods ended June 30, 2025. Key Highlights: • Revenues were $465.3 million for the quarter, up $88.2 million, or up 23.4%, from the same period in 2024. • Solid waste pricing for the quarter was up 5.0% from the same period in 2024, with 4.9% collection price growth and 5.8% disposal price growth. • Net income was $5.2 million for the quarter, down $(1.8) million, or down (25.7)%, as compared to $7.0 million for the same period in 2024. • Adjusted EBITDA, a non-GAAP measure, was $109.5 million for the quarter, up $17.9 million, or up 19.5%, from the same period in 2024. • Net cash provided by operating activities was $139.6 million for the year-to-date period, up $59.9 million from the same period in 2024. • Adjusted Free Cash Flow, a non-GAAP measure, was $70.8 million for the year-to-date period, up $31.3 million from the same period in 2024. • Acquired six businesses year-to-date with approximately $90 million in annualized revenue, with another $30 million to come with the anticipated closing of the recently announced Mountain State Waste transaction. “We delivered strong growth again in the second quarter across our key financial metrics, as we continue to execute on our operating plans and acquisition strategy, including six acquisitions completed in the first half of this year with over $90 million in annualized revenue,” said John W. Casella, Chairman and CEO of Casella Waste Systems, Inc. “We are excited about our pending acquisition of Mountain State Waste, which will expand our footprint in Pennsylvania and into the adjacent West Virginia market, and look forward to welcoming their employees and customers to Casella.” “In the base business, we again delivered consistent same store organic growth in revenue, Adjusted EBITDA and Adjusted Free Cash Flow, driven in particular by performance across our legacy Northeast footprint and stronger landfill volumes year-over-year,” Casella said. “From a margin perspective, our recent acquisition activity, where we tend to acquire private businesses at initial Adjusted EBITDA margins below our consolidated levels, as well as the pace of synergy realization in the Mid-Atlantic, were a near-term headwind, but represent opportunities for margin expansion going forward.” Q2 2025 Results Revenues were $465.3 million for the quarter, up $88.2 million, or up 23.4%, from the same period in 2024, with revenue growth mainly driven by: the rollover impact from acquisitions, including deals closed in prior periods; sustained collection and disposal price growth; and strong National Accounts growth in our Resource Solutions segment. Operating income was $19.3 million for the quarter, down $(3.7) million, or down (16.3)%, from the same period in 2024, primarily impacted by higher depreciation and amortization expense related to acquisition growth. Net income was $5.2 million for the quarter, down $(1.8) million, or down (25.7)%, from the same period in 2024, largely driven by the factors impacting operating income. Adjusted Net Income was $23.0 million for the quarter, up $1.3 million, or up 5.9% from the same period in 2024. Adjusted EBITDA was $109.5 million for the quarter, up $17.9 million, or up 19.5%, from the same period in 2024, driven by both acquisition contribution and organic growth . Please refer to "Non-GAAP Performance Measures" included in "Unaudited Reconciliation of Certain Non-GAAP Measures" below for additional information and reconciliations of Adjusted Net Income, Adjusted Diluted Earnings Per Common Share, Adjusted EBITDA and other non-GAAP performance measures to their most directly comparable GAAP measures. 1 Net cash provided by operating activities was $139.6 million for the six months ended June 30, 2025, up $59.9 million from $79.8 million for the same period in 2024, driven by both acquisition contribution and organic growth, lower cash interest payments and a lower outflow from changes in working capital compared to the same period in 2024. Adjusted Free Cash Flow for the six months ended June 30 was $70.8 million , up $31.3 million from $39.5 million for the same period in 2024. Please refer to "Non-GAAP Liquidity Measures" included in "Unaudited Reconciliation of Certain Non-GAAP Measures" below for additional information and reconciliation of Adjusted Free Cash Flow to its most directly comparable GAAP measure. Fiscal Year 2025 Outlook “We are increasing revenue guidance, reflecting our acquisition activity in the first half; raising the bottom end of the range for Adjusted Free Cash Flow, reflecting strong cash flow performance in the first half and our increased confidence in the second half; and reaffirming our guidance range for Adjusted EBITDA, as the contribution from additional acquisitions to date have not moved us outside of our original guidance range,” Casella said. The Company updated guidance for the fiscal year ending December 31, 2025 ("fiscal year 2025") by estimating results in the following range: • Revenues between $1.820 billion and $1.840 billion (raised from a range of $1.775 billion to $1.805 billion); • Net income between $8 million and $18 million (revised from a range of $10 million to $25 million); • Net cash provided by operating activities between $325 million and $335 million (revised from a range of $320 million to $335 million); and • Adjusted Free Cash Flow between $170 million and $180 million (revised from a range of $165 million to $180 million). The Company reaffirmed guidance for fiscal year 2025 by estimating results in the following range: • Adjusted EBITDA between $410 million and $425 million. The guidance ranges include acquisition activity completed to date, including the $90 million of annualized revenue acquired in the first half of 2025, but do not include the impact of any acquisitions that have not been completed, including the acquisition of Mountain State Waste. Adjusted EBITDA and Adjusted Free Cash Flow related to fiscal year 2025 are described in the Unaudited Reconciliation of Fiscal Year 2025 Outlook Non-GAAP Measures section of this press release. Net income and Net cash provided by operating activities are provided as the most directly comparable GAAP measures to Adjusted EBITDA and Adjusted Free Cash Flow, respectively, however these forward-looking estimates for fiscal year 2025 do not contemplate any unanticipated impacts.

AND SUBSIDIARIES UNAUDITED RECONCILIATION OF CERTAIN NON-GAAP MEASURES (In thousands) Non-GAAP Performance Measures In addition to disclosing financial results prepared in accordance with generally accepted accounting principles in the United States ("GAAP"), the Company also presents non-GAAP performance measures such as Adjusted EBITDA, Adjusted EBITDA as a percentage of revenues, Adjusted Operating Income, Adjusted Net Income and Adjusted Diluted Earnings Per Common Share that provide an understanding of operational performance because it considers them important supplemental measures of the Company's performance that are frequently used by securities analysts, investors and other interested parties in the evaluation of the Company's results. The Company also believes that identifying the impact of certain items as adjustments provides more transparency and comparability across periods. Management uses these non-GAAP performance measures to further understand its “core operating performance” and believes its “core operating performance” is helpful in understanding its ongoing performance in the ordinary course of operations. The Company believes that providing such non-GAAP performance measures to investors, in addition to corresponding income statement measures, affords investors the benefit of viewing the Company’s performance using the same financial metrics that the management team uses in making many key decisions and understanding how the core business and its results of operations has performed. The tables below set forth such performance measures on an adjusted basis to exclude such items: Three Months Ended June 30, Six Months Ended June 30, 2025 2024 2025 2024 Net income $ 5,208 $ 7,006 $ 398 $ 2,889 Provision (benefit) for income taxes 1,679 3,792 (1,647) 2,025 Other income (615) (477) (933) (828) Interest expense, net 13,000 12,697 24,598 25,767 Depreciation and landfill amortization 57,889 43,100 109,914 84,572 Amortization of intangibles (i) 19,117 12,238 38,583 24,803 Expense from acquisition activities (ii) 6,463 7,836 11,992 12,847 Depletion of landfill operating lease obligations 3,050 2,497 5,589 4,695 Interest accretion on landfill and environmental remediation liabilities 3,715 2,926 7,426 5,862 Adjusted EBITDA $ 109,506 $ 91,615 $ 195,920 $ 162,632 Adjusted EBITDA as a percentage of revenues 23.5 % 24.3 % 22.2 % 22.6 % Depreciation and landfill amortization (57,889) (43,100) (109,914) (84,572) Depletion of landfill operating lease obligations (3,050) (2,497) (5,589) (4,695) Interest accretion on landfill and environmental remediation liabilities (3,715) (2,926) (7,426) (5,862) Adjusted Operating Income $ 44,852 $ 43,092 $ 72,991 $ 67,503 7 Three Months Ended June 30, Six Months Ended June 30, 2025 2024 2025 2024 Net income $ 5,208 $ 7,006 $ 398 $ 2,889 Amortization of intangibles (i) 19,117 12,238 38,583 24,803 Expense from acquisition activities (ii) 6,463 7,836 11,992 12,847 Tax effect (iii) (7,837) (5,411) (15,827) (10,148) Adjusted Net Income $ 22,951 $ 21,669 $ 35,146 $ 30,391 Diluted weighted average common shares outstanding 63,563 58,199 63,524 58,161 Diluted earnings per common share $ 0.08 $ 0.12 $ 0.01 $ 0.05 Amortization of intangibles (i) 0.30 0.21 0.61 0.43 Expense from acquisition activities (ii) 0.10 0.13 0.19 0.22 Tax effect (iii) (0.12) (0.09) (0.26) (0.18) Adjusted Diluted Earnings Per Common Share $ 0.36 $ 0.37 $ 0.55 $ 0.52 (i) Amortization of intangibles is the add-back of non-cash amortization of acquired intangibles such as covenants not-to-compete, customer relationships and trade names. (ii) Expense from acquisition activities is comprised primarily of legal, consulting, rebranding, information technology and other costs associated with the due diligence, acquisition and integration of acquired businesses. The three and six months ended June 30, 2024 included a charge for an increase in the reserve against accounts receivable of the businesses acquired in the acquisition of four wholly owned subsidiaries of GFL Environmental Inc., as a result of our inability to pursue collections during the transition services period with the seller, resulting in accounts receivable aged beyond what is typical in our business. (iii) Tax effect of the adjustments is an aggregate of the current and deferred tax impact of each adjustment, including the impact to the effective tax rate, current provision and deferred provision. The computation considers all relevant impacts of the adjustments, including available net operating loss carryforwards and the impact on the remaining valuation allowance. 8 Non-GAAP Liquidity Measures In addition to disclosing financial results prepared in accordance with GAAP, the Company also presents non-GAAP liquidity measures such as Adjusted Free Cash Flow that provide an understanding of the Company's liquidity because it considers them important supplemental measures of its liquidity that are frequently used by securities analysts, investors and other interested parties in the evaluation of the Company's cash flow generation from its core operations that are then available to be deployed for strategic acquisitions, growth investments, development projects, unusual landfill closures, site improvement and remediation, and strengthening the Company’s balance sheet through paying down debt. The Company also believes that showing the impact of certain items as adjustments provides more transparency and comparability across periods. Management uses non-GAAP liquidity measures to understand the Company’s cash flow provided by operating activities after certain expenditures along with its consolidated net leverage and believes that these measures demonstrate the Company’s ability to execute on its strategic initiatives. The Company believes that providing such non-GAAP liquidity measures to investors, in addition to corresponding cash flow statement measures, affords investors the benefit of viewing the Company’s liquidity using the same financial metrics that the management team uses in making many key decisions and understanding how the core business and cash flow generation has performed. The table below, on an adjusted basis to exclude certain items, sets forth such liquidity measures: Three Months Ended June 30, Six Months Ended June 30, 2025 2024 2025 2024 Net cash provided by operating activities $ 89,525 $ 72,102 $ 139,648 $ 79,781 Capital expenditures (66,403) (44,649) (121,878) (74,900) Proceeds from sale of property and equipment 287 339 503 827 Southbridge Landfill closure (i) — 787 — 1,482 Cash outlays for acquisition expenses (ii) 5,442 4,941 11,768 9,435 Acquisition capital expenditures (iii) 12,117 6,571 39,986 12,659 McKean Landfill rail capital expenditures (iv) 800 1,030 800 3,225 FLSA legal settlement payment (v) — — — 6,150 Landfill capping charge - veneer failure payment (vi) — 794 — 850 Adjusted Free Cash Flow $ 41,768 $ 41,915 $ 70,827 $ 39,509 (i) Southbridge Landfill closure are cash outlays associated with the unplanned, early closure of our landfill located in Southbridge, Massachusetts (“Southbridge Landfill”). The Company initiated the unplanned, premature closure of the Southbridge Landfill in the fiscal year ended December 31, 2017, and expects to incur cash outlays through satisfaction of the closure requirements and the environmental remediation process. In August 2024, the Company received the final closure permit related to Southbridge Landfill and entered the post-closure period. (ii) Cash outlays for acquisition expenses are cash outlays for transaction and integration costs relating to specific acquisition transactions and include legal, consulting, rebranding, information technology and other costs as part of the Company’s strategic growth initiative. (iii) Acquisition capital expenditures are acquisition-related capital expenditures that are necessary to transition and upgrade acquired assets to Company operating standards and to achieve strategic synergies associated with integrating newly acquired operations, which can be considered, together with acquisition purchase price, as part of the initial overall investment in an acquired business. (iv) McKean Landfill rail capital expenditures are long-term infrastructure capital expenditures related to rail side development at the Company's landfill in Mount Jewett, PA ("McKean Landfill"), which is different from the landfill construction investments in the normal course of operations. (v) FLSA legal settlement payment is the cash outlay of a legal settlement related to reaching an agreement in June 2023 with the collective class members of a class action lawsuit relating to certain claims under the Fair Labor Standards Act of 1938 ("FLSA") as well as state wage and hours laws. (vi) Landfill capping charge - veneer failure payment is the cash outlay associated with operating expenses incurred to clean up the affected capping material at the Company's landfill in Seneca, New York that has been reimbursed to us by a third party. 9 Non-GAAP financial measures are not in accordance with or an alternative for GAAP.
