FOR IMMEDIATE RELEASE

CASELLA WASTE SYSTEMS, INC. ANNOUNCES THIRD QUARTER 2022 RESULTS AND UPDATES FISCAL YEAR 2022 GUIDANCE

•Solid third quarter results demonstrated continued execution against the Company's operating initiatives, pricing programs, and disciplined growth strategy.

•The Company raised its revenue, net income, Adjusted EBITDA, and net cash provided by operating activities guidance ranges for the fiscal year ending December 31, 2022 ("fiscal year 2022").

RUTLAND, VERMONT (October 27, 2022) — 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 nine month periods ended September 30, 2022.

Highlights for the Three Months and Year-to-Date Period Ended September 30, 2022:

•Revenues were $295.3 million for the quarter, up $53.3 million, or up 22.0%, from the same period in 2021.

•Overall solid waste pricing for the quarter was up 6.6%, driven by collection pricing, up 7.2%, and disposal pricing, up 6.0%, from the same period in 2021.

•Net income was $22.7 million for the quarter, up $6.8 million, or up 42.9%, from the same period in 2021.

•Adjusted EBITDA, a non-GAAP measure, was $75.0 million for the quarter, up $13.8 million, or up 22.5%, from the same period in 2021.

•Net cash provided by operating activities was $152.4 million for the year-to-date period, up $18.3 million, or up 13.7%, from the same period in 2021.

•Adjusted Free Cash Flow, a non-GAAP measure, was $81.7 million for the year-to-date period, up $3.4 million, or up 4.3%, from the same period in 2021.

•Acquired 13 businesses year-to-date with approximately $48 million of annualized revenues.

"We posted another strong quarter as our operating and pricing initiatives worked well to offset inflation and drive Adjusted EBITDA growth of 22.5% year-over-year in the quarter," said John W. Casella, Chairman and CEO of Casella Waste Systems, Inc. "As expected, we expanded Adjusted EBITDA margins in the third quarter despite significant declines in commodity prices, acquisition headwinds, and the negative impact from the accrual of a special bonus we will pay in December to our hourly employees in recognition of their excellent work."

"Our team is doing a great job navigating a complex economic environment, while offsetting historically high inflation through operating initiatives and nimble pricing programs," Casella said. "We continue to invest in key operating initiatives that are improving our service efficiency, reducing costs, and improving our team's safety. Further, a 6.6% increase in solid waste price demonstrates the flexibility we have in our programs to offset inflation."

"Our fuel cost recovery program is working well and fully mitigated the impact of higher fuel costs in the third quarter," Casella said. "With the changes we made late in the second quarter, we now anticipate that our fuel cost recovery program will recoup the impact of higher fuel costs this year."

“On top of the strong organic growth in our core business, acquisitions remain a key part of our overall strategy. Year-to-date, we have closed on 13 acquisitions with annualized revenues of approximately $48 million. Our pipeline remains robust, and we are actively working to close several additional acquisitions in the next several quarters," Casella said.

For the quarter, revenues were $295.3 million, up $53.3 million, or up 22.0%, from the same period in 2021, with revenue growth mainly driven by: the roll-over impact from acquisitions along with newly closed acquisitions; positive collection and disposal pricing; higher solid waste fuel cost recovery fees; and higher pricing, recycling processing fees and volume within our Resource Solutions operating segment; partially offset by lower recycling commodity prices.

Net income was $22.7 million for the quarter, or $0.44 per diluted common share, up $6.8 million, or up 42.9%, as compared to net income of $15.9 million, or $0.31 per diluted common share, for the same period in 2021. Adjusted Net Income, a non-GAAP measure, was $23.1 million for the quarter, or $0.45 Adjusted Diluted Earnings Per Common Share, a non-GAAP measure, up $5.6 million, or up 31.9%, as compared to Adjusted Net Income of $17.5 million, or $0.34 Adjusted Diluted Earnings Per Common Share, for the same period in 2021.

Operating income was $36.3 million for the quarter, up $8.9 million, or up 32.5%, from the same period in 2021. Adjusted EBITDA was $75.0 million for the quarter, up $13.8 million, or up 22.5%, from the same period in 2021.

For the year-to-date period, revenues were $813.0 million, up $165.6 million, or up 25.6%, from the same period in 2021. Net income was $44.7 million, or $0.86 per diluted common share, for the year-to-date period, as compared to net income of $32.0 million, or $0.62 per diluted common share, for the same period in 2021. Adjusted Net Income was $47.4 million, or $0.92 Adjusted Diluted Earnings Per Common Share, for the year-to-date period, as compared to Adjusted Net Income of $35.3 million, or $0.68 Adjusted Diluted Earnings Per Common Share, for the same period in 2021.

Operating income was $78.2 million for the year-to-date period, up $16.8 million from the same period in 2021.Adjusted EBITDA was $189.0 million for the year-to-date period, up $36.9 million from the same period in 2021.

Please refer to "Non-GAAP Performance Measures" included in "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.

Please refer to "Non-GAAP Liquidity Measures" included in "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 2022 Outlook

“Given our strong operating execution year-to-date, the expected positive contribution of acquisitions completed this year and greater visibility through year-end, we are updating certain fiscal year 2022 guidance ranges for the third time this year,” Casella said. “These guidance ranges assume that the economy does not significantly change through the remainder of the year, inflation remains at current historically high levels, and recycling commodity prices decline another 20% sequentially. We expect our pricing, fuel cost recovery fees, and operating efficiency programs will allow us to outpace higher costs and drive margin expansion in the fourth quarter which sets us up well for 2023.”

The Company raised guidance for fiscal year 2022 by estimating results in the following ranges:

•Revenues between $1.065 billion and $1.080 billion (raised from a range of $1.035 billion to $1.050 billion);

•Net income between $53 million and $56 million (raised from a range of $50 million to $54 million);

•Adjusted EBITDA between $245 million and $248 million (raised from a range of $238 million to $242 million); and

•Net cash provided by operating activities between $210 million and $214 million (raised from a range of $208 million to $212 million).

The Company reaffirmed certain guidance for fiscal year 2022 by estimating results in the following ranges:

•Adjusted Free Cash Flow between $106 million and $110 million.

Adjusted EBITDA and Adjusted Free Cash Flow related to fiscal year 2022 are described in the Reconciliation of Fiscal Year 2022 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 2022 do not contemplate any unanticipated or non-recurring impacts.

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 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:

(ii)Expense from acquisition activities is primarily legal, consulting or other similar costs incurred during the period associated with due diligence and the acquisition and integration of acquired businesses or select development projects as part of the Company’s strategic growth initiative.

(iii)Southbridge Landfill closure charge are expenses related to the unplanned early closure of the Southbridge Landfill along with associated legal activities. The Company initiated the unplanned, premature closure of the Southbridge Landfill in the fiscal year ended December 31, 2017 due to the significant capital investment required to obtain expansion permits and for future development coupled with an uncertain regulatory environment. The unplanned closure of the Southbridge Landfill reduced the economic useful life of the assets from prior estimates by approximately ten years. The Company expects to incur certain costs through completion of the closure process.

(iv)Environment remediation charge associated with the investigation of potential remediation at an inactive waste disposal site that adjoins one of the landfills we operate.

(v)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.

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 identifying 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 September 30,				Nine Months Ended September 30,
	2022		2021		2022		2021
Net cash provided by operating activities	$	60,180	$	55,076	$	152,431	$	134,089

Adjusted Free Cash Flow	$	35,437	$	40,688	$	81,685	$	78,310

(i)Southbridge Landfill closure and Potsdam environmental remediation are cash outlays associated with the unplanned closure of the Southbridge Landfill and the Company's portion of costs associated with environmental remediation at Potsdam, which are added back when calculating Adjusted Free Cash Flow due to their non-recurring nature and the significance of the related cash flows. The Company initiated the unplanned closure of the Southbridge Landfill in the fiscal year ended December 31, 2017 and expects to incur cash outlays through completion of the closure and environmental remediation process. The Potsdam site was deemed a Superfund site in 2000 and is not associated with current operations.

(ii)Cash outlays from acquisition activities are cash outlays for transaction and integration costs relating to specific acquisition transactions and include legal, environmental, valuation and consulting as well as asset, workforce and system integration costs as part of the Company’s strategic growth initiative.

(iii)Post acquisition and development project capital expenditures are (x) acquisition related capital expenditures that are necessary to optimize strategic synergies associated with integrating newly acquired operations as contemplated by the discounted cash flow return analysis conducted by management as part of the acquisition investment decision; and (y) non-routine development investments that are expected to provide long-term returns. Acquisition related capital expenditures include costs required to achieve initial operating synergies and integrate operations.

(iv)Waste USA Landfill phase VI capital expenditures related to the Company's landfill in Coventry, Vermont ("Waste USA Landfill") phase VI construction and development that are added back when calculating Adjusted Free Cash Flow due to the specific nature of this investment in the development of long-term infrastructure which is different from landfill construction investments in the normal course of operations. This investment at the Waste USA Landfill is unique because the Company is investing in long-term infrastructure over an estimated four year period that will not yield a positive economic benefit until 2023 and extending over approximately 20 years.

(i)The Company's capital expenditures are broadly defined as pertaining to either growth or replacement activities. Growth capital expenditures are defined as costs related to development projects, organic business growth, and the integration of newly acquired operations. Growth capital expenditures include costs related to the following: 1) post acquisition and development projects that are necessary to optimize strategic synergies associated with integrating newly acquired operations as contemplated by the discounted cash flow return analysis conducted by management as part of the acquisition investment decision as well as non-routine development investments that are expected to provide long-term returns and includes the capital expenditures required to achieve initial operating synergies and integrate operations; 2) Waste USA Landfill phase VI construction and development for long-term infrastructure, which is unique and different from landfill construction investments in the normal course of operations because the Company is investing in long-term infrastructure over an estimated four year period that will not yield a positive economic benefit until 2023 and extending over approximately 20 years; and 3) development of new airspace, permit expansions, and new recycling contracts, equipment added directly as a result of organic business growth and infrastructure added to increase throughput at transfer stations and recycling facilities. Replacement capital expenditures are defined as landfill cell construction costs not related to expansion airspace, costs for normal permit renewals, and replacement costs for equipment due to age or obsolescence.
