" We delivered another quarter of solid financial and operating performance as our teams continued to execute at a high level across the business , " said Ned Coletta , President and CEO of Casella Waste Systems , Inc. “ Our disciplined operating approach , strong pricing execution , healthy landfill volumes , and continued acquisition activity drove positive results during the quarter . The momentum we have built through the first half of the year , together with the strength of our operating platform , reinforces our confidence in our strategy and execution for the remainder of the year . " " Our core business continued to perform well during the quarter , ” Coletta said . " Solid waste pricing remained strong , including disposal pricing of 4.7 % , with municipal solid waste and construction & demolition pricing growth of 4.5 % at the landfills . As we advanced pricing , landfill volumes also increased year - over - year with the growth related to both third party - sales and internalization efforts . " " Notably , as fuel prices rapidly increased this year and remained elevated through the second quarter , our floating fuel recovery fees offset this higher cost , although resulting in a headwind to Adjusted EBITDA margins of 40 basis points . At the same time , our teams remained focused on driving results through our key operating programs as well as acquisition integration , including continued progress within our Mid - Atlantic region , where we have completed our systems integration work , initiated various route optimization initiatives , and look to further execute against our plan in the second half of the year . ' " “ Our acquisition pipeline remains very strong , ” Coletta said . “ We have closed on five acquisitions so far this year with total annualized revenues of approximately $ 165 million , and I would like to again welcome our new team members and customers . " Q2 2026 Results Revenues were $ 543.7 million for the quarter , up $ 78.4 million , or up 16.9 % , from the same period in 2025 , with revenue growth mainly driven by : the positive impact from acquisitions , including the rollover contribution from deals closed in prior periods ; positive collection and disposal price ; an increase in landfill volumes ; and strong National Accounts growth in our Resource Solutions operating segment .

Fiscal Year 2026 Outlook “We are increasing our revenue guidance reflecting our acquisition activity and expectation of higher floating fuel recovery fees associated with offsetting elevated fuel costs,” Coletta said. “The business is performing in line with plan and our outlook for the year has not materially changed.” The Company updated guidance for the fiscal year ending December 31, 2026 (“fiscal year 2026”) for the following ranges: • Revenues between $2.090 billion and $2.110 billion (raised from a range of $2.060 billion to $2.080 billion); and • Net income between $0 and $6 million (lowered from a range of $4 million to $10 million). The Company reaffirmed guidance for fiscal year 2026 by estimating results in the following ranges: • Adjusted EBITDA between $473 million and $483 million; • Net cash provided by operating activities between $370 million and $380 million; and • Adjusted Free Cash Flow between $200 million and $210 million. The guidance ranges do not include the impact of any acquisitions that have not been completed.

CASELLA WASTE SYSTEMS, INC. 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 GAAP, the Company also presents non-GAAP performance measures such as Adjusted EBITDA, Adjusted EBITDA as a percentage of revenues, Adjusted Operating Income, Adjusted Operating Income as a percentage of revenues, 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 EndedJune 30, Six Months EndedJune 30, 2026 2025 2026 2025 Net income (loss) $ 3,770 $ 5,208 $ (1,769) $ 398 Net income (loss) as a percentage of revenues 0.7 % 1.1 % (0.2)% — % (Benefit) provision for income taxes (405) 1,679 (3,690) (1,647) Other income (822) (615) (1,136) (933) Interest expense, net 17,421 13,000 31,414 24,598 Depreciation and landfill amortization 66,468 57,889 126,075 109,914 Amortization of intangibles (i) 22,030 19,117 40,406 38,583 Expense from acquisition activities (ii) 6,081 6,463 12,590 11,992 Organics facility closure charge, net (iii) 927 — 1,697 — Depletion of landfill operating lease obligations 3,746 3,050 6,704 5,589 Interest accretion on landfill and environmental remediation liabilities 4,022 3,715 8,021 7,426 Adjusted EBITDA $ 123,238 $ 109,506 $ 220,312 $ 195,920 Adjusted EBITDA as a percentage of revenues 22.7 % 23.5 % 22.0 % 22.2 % Depreciation and landfill amortization (66,468) (57,889) (126,075) (109,914) Depletion of landfill operating lease obligations (3,746) (3,050) (6,704) (5,589) Interest accretion on landfill and environmental remediation liabilities (4,022) (3,715) (8,021) (7,426) Adjusted Operating Income $ 49,002 $ 44,852 $ 79,512 $ 72,991 Adjusted Operating Income as a percentage of revenues 9.0 % 9.6 % 7.9 % 8.3 % 7

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 EndedJune 30, Six Months EndedJune 30, 2026 2025 2026 2025 Net cash provided by operating activities $ 98,773 $ 89,525 $ 161,026 $ 139,648 Capital expenditures (72,309) (66,403) (122,288) (121,878) Proceeds from sale of property and equipment 279 287 640 503 Acquisition capital expenditures (i) 11,369 12,117 20,610 39,986 Cash outlays for acquisition expenses (ii) 5,768 5,442 12,761 11,768 McKean Landfill rail capital expenditures (iii) 2,893 800 4,476 800 Cash outlays for organics facility closure, net (iv) 692 — 893 — Adjusted Free Cash Flow $ 47,465 $ 41,768 $ 78,118 $ 70,827 (i) 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. (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) 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. (iv) Cash outlays for organics facility closure, net are net cash outlays related to us ceasing operations at an organic residuals composting facility that we own in Maine related to a change in state law prohibiting land application of biosolids based recycled products. We expect to incur cash outlays through satisfaction of the closure requirements and the soil remediation process. Non-GAAP financial measures are not in accordance with or an alternative for GAAP. Adjusted EBITDA, Adjusted EBITDA as a percentage of revenues, Adjusted Operating Income, Adjusted Operating Income as a percentage of revenues, Adjusted Net Income, Adjusted Diluted Earnings Per Common Share, and Adjusted Free Cash Flow should not be considered in isolation from or as a substitute for financial information presented in accordance with GAAP, and may be different from Adjusted EBITDA, Adjusted EBITDA as a percentage of revenues, Adjusted Operating Income, Adjusted Operating Income as a percentage of revenues, Adjusted Net Income, Adjusted Diluted Earnings Per Common Share, and Adjusted Free Cash Flow presented by other companies. 9
