RUTLAND, Vt., Feb. 17, 2022 (GLOBE NEWSWIRE) -- 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 twelve month periods ended December 31, 2021. The Company also provided guidance for the fiscal year ending December 31, 2022 ("fiscal year 2022").

Highlights for the Three and Twelve Months Ended December 31, 2021:

Net income was $41.1 million for fiscal year 2021, down $(50.0) million, or down (54.9)%, million from fiscal year 2020. The fourth quarter of fiscal year 2020 included a $55.0 million non-recurring benefit to income taxes due to the reversal of a valuation allowance.
• Adjusted Net Income, a non-GAAP measure, was $11.0 million for the quarter, up $2.2 million, or up 25.6%, from the same period in 2020. Adjusted Net Income was $46.3 million for fiscal year 2021, up $5.4 million, or up 13.3%, from fiscal year 2020.
• Adjusted EBITDA, a non-GAAP measure, was $51.4 million for the quarter, up $8.8 million, or up 20.6%, from the same period in 2020. Adjusted EBITDA was $203.6 million for fiscal year 2021, up $32.2 million, or up 18.8%, from fiscal year 2020.
• Net cash provided by operating activities was $182.7 million for fiscal year 2021, up $42.8 million, or up 30.6%, from fiscal year 2020.
• Adjusted Free Cash Flow, a non-GAAP measure, was $95.3 million for fiscal year 2021, up $26.2 million, or up 37.9%, from fiscal year 2020.
• Acquired ten businesses with approximately $88 million of annualized revenues in fiscal year 2021.

“We had another great quarter and arguably the best year in the company’s history, as we continued to execute well against our long-term strategic plan, driving improved financial results and lasting operational benefits, despite lingering challenges from the COVID-19 pandemic, labor shortages and rising inflation,” said John W. Casella, Chairman and CEO of Casella Waste Systems, Inc. “As a result, we increased revenues by 14.8%, Adjusted EBITDA by 18.8%, and Adjusted Free Cash Flow by 37.9% year-over-year in fiscal year 2021.”

“These strong results are a result of the hard work, dedication and adaptability of our team, our asset positioning in the disposal capacity constrained northeast market, continued achievement of our operating and cost efficiency programs, and strong execution of our growth strategy,” Casella said. “As expected, our solid waste pricing continued to improve sequentially as we advanced 4.3% solid waste pricing during the fourth quarter, with strength in both collection and disposal lines-of-business. We have launched a robust pricing program for 2022, with early data indicating further sequential improvements and limited roll-backs.”

“Inflation for certain costs categories edged up sequentially in the fourth quarter, and our team continued to do an excellent job offsetting higher costs through key operating and technology initiatives, including our route optimization program, continued automation of our fleet, real-time data analytics, and variable pricing programs such as our energy and environmental fees,” Casella said. “Excluding a 35 basis point negative headwind to margins from businesses acquired in fiscal year 2021, our margins were up in the fourth quarter, with our pricing and efficiency programs effectively offsetting inflation.”

“We continue to execute well against our long-term growth strategy, as we acquired ten businesses with approximately $88 million of annualized revenues in fiscal year 2021,” Casella said. "And, we are off to a solid start in fiscal year 2022, as we have acquired five tuck-in acquisitions year-to-date with approximately $4 million of annualized revenues. We expect to recognize roughly $55 million of revenues in 2022 from the roll-over impact of acquisitions completed throughout 2021 and already completed in 2022.”

“We are focused on acquiring well run businesses in strategic markets that will drive long-term growth, additional vertical integration and enhance operating synergies,” Casella said. “Our acquisition pipeline remains robust, and we believe that there is continued opportunity to drive additional cash flow growth across our footprint through execution of our growth strategy.”

For the quarter, revenues were $241.8 million, up $41.6 million, or up 20.8%, from the same period in 2020, with revenue growth mainly driven by: the roll-over impact from acquisitions; positive collection and disposal pricing; higher solid waste volumes; higher recycling commodity prices; higher resource solutions processing volumes; and higher resource solutions non-processing volumes; partially offset by lower Sustainability Recycling Adjustment fees as we share higher commodity prices with our customers.

Net income was $9.1 million for the quarter, or $0.18 per diluted common share, down $(53.8) million, or down (85.5)%, as compared to net income of $62.9 million, or $1.24 per diluted common share, for the same period in 2020. Adjusted Net Income, a non-GAAP measure, was $11.0 million for the quarter, or $0.21 Adjusted Diluted Earnings Per Common Share, a non-GAAP measure, up $2.2 million, or up 25.6%, as compared to Adjusted Net Income of $8.8 million, or $0.17 Adjusted Diluted Earnings Per Common Share, for the same period in 2020. The fourth quarter in 2020 included a $55.0 million non-recurring benefit to income taxes adjustment due to the reversal of a valuation allowance on the majority of our net operating loss carryforwards and other deferred tax assets.

Operating income was $16.3 million for the quarter, up $2.1 million, or up 14.8%, from the same period in 2020. Adjusted Operating Income, a non-GAAP measure, was $18.4 million for the quarter, up $3.1 million, or up 20.4% from the same period in 2020. Adjusted EBITDA was $51.4 million for the quarter, up $8.8 million, or up 20.6%, from the same period in 2020.

For fiscal year 2021, revenues were $889.2 million, up $114.6 million, or up 14.8%, from fiscal year 2020. Net income was $41.1 million, or $0.80 per diluted common share, for fiscal year 2021, as compared to net income of $91.1 million, or $1.86 per diluted common share, for fiscal year 2020. Adjusted Net Income was $46.3 million, or $0.90 Adjusted Diluted Earnings Per Common Share, for fiscal year 2021, as compared to Adjusted Net Income of $40.8 million, or $0.83 Adjusted Diluted Earnings Per Common Share, for fiscal year 2020. Fiscal year 2020 included a $55.0 million non-recurring benefit to income taxes adjustment due to the reversal of a valuation allowance on the majority of our net operating loss carryforwards and other deferred tax assets.

Operating income was $77.7 million for fiscal year 2021, up $18.4 million from fiscal year 2020. Adjusted Operating Income was $84.4 million for fiscal year 2021, up $18.6 million from fiscal year 2020. Adjusted EBITDA was $203.6 million for fiscal year 2021, up $32.2 million from fiscal year 2020.

See Non-GAAP Performance Measures included in the Reconciliation of Certain Non-GAAP Measures for further disclosure over the various adjustments to estimated Adjusted Net Income, Adjusted Diluted Earnings Per Common Share, Adjusted Operating Income and Adjusted EBITDA.

Net cash provided by operating activities was $182.7 million for fiscal year 2021, as compared to $139.9 million for fiscal year 2020. Adjusted Free Cash Flow was $95.3 million for fiscal year 2021, as compared to $69.1 million for fiscal year 2020 (See full reconciliation of Non-GAAP measures in the tables below).

See Non-GAAP Liquidity Measures included in the Reconciliation of Certain Non-GAAP Measures for further disclosure over the various adjustments to Adjusted Free Cash Flow.

Fiscal Year 2022 Outlook

“Our guidance ranges assume a stable economic environment continuing from the fourth quarter 2021 through the remainder of 2022,” Casella said. “We believe that we have established an appropriate pricing plan for 2022 that positions us to offset inflationary headwinds, while still improving margins through our investments in technology and core operating programs. Further, we have several exciting resource solutions projects planned for 2022, including: a full equipment upgrade to our Boston, Massachusetts recycling facility to improve throughput and increase efficiencies; the introduction of robotics and optical sorting technologies to additional recycling facilities; and two renewable natural gas projects at our landfills, where a third party is making the capital investments and we will receive gas royalties.”

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

• Revenues between $980 million and $995 million (as compared to $889.2 million in fiscal year 2021);
• Net income between $48 million and $52 million (as compared to $41.1 million in fiscal year 2021);
• Adjusted EBITDA between $228 million and $232 million (as compared to $203.6 million in fiscal year 2021);
• Net cash provided by operating activities between $202 million and $206 million (as compared to $182.7 million in fiscal year 2021); and
• Adjusted Free Cash Flow between $104 million and $108 million (as compared to $95.3 million in fiscal year 2021).
  

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.

The Company provided the following assumptions that are built into its outlook:

• Overall, the Company expects revenue growth of between 10.2% and 11.9% in fiscal year 2022, including approximately 6.2% (or $55 million) revenue growth from the roll-over impact of acquisitions completed during fiscal year 2021 and those already completed in early fiscal year 2022.
• Does not include the impact of any acquisitions that have not yet been completed.
• In the Solid Waste business, revenue growth of between 13.3% and 14.3%, with price growth from 4.5% to 5.0%, volume growth from 1.5% to 2.0%, and 7.3% growth from acquisitions completed during fiscal year 2021 and those already completed in early fiscal year 2022.
• In the resource solutions business, revenue growth of between 4.0% and 5.0%, mainly driven by 3.0% growth from acquisitions completed during fiscal year 2021 and slightly higher volumes, partially offset by lower recycling commodity prices.
• Capital expenditures of approximately $120 million, which includes approximately $15 million of non-recurring capital associated with acquisition integration.
• Net cash provided by operating activities will be negatively impacted in fiscal year 2022 as we plan to spend $6.5 million on landfill closure, site improvement and remediation expenditures associated with the Southbridge Landfill closure. We expect the Southbridge Landfill closure project to be substantially completed in fiscal year 2022.

RECONCILIATION OF CERTAIN NON-GAAP MEASURES
(Unaudited)
(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:

(i)	Expense from acquisition activities is primarily legal, consulting or other similar costs incurred during the period related to acquisition diligence, acquisition integration or select development projects as part of the Company’s strategic growth initiative.
(ii)	Southbridge Landfill closure (credit) charge, net is 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 Company's landfill in Southbridge, Massachusetts ("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.
(iii)	Environmental remediation charge is associated with a settlement associated with the Company's landfill in Bethlehem, New Hampshire ("NCES Landfill").
(iv)	Valuation allowance consists of the income tax benefit associated with the Company's assessment on the recoverability of deferred tax assets and the resulting unwinding of the Company's valuation allowance pertaining to the majority of its net operating loss carryforwards and other deferred tax assets.
(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 tables below, in some instances on an adjusted basis to exclude certain items, set forth such liquidity measures:

	Three Months Ended December 31,								Twelve Months Ended December 31,
		2021				2020				2021				2020
Net cash provided by operating activities	$	48,648			$	28,007			$	182,737			$	139,922
Capital expenditures		(41,718	)			(30,837	)			(123,295	)			(108,108	)
Proceeds from sale of property and equipment		195				103				788				533
Southbridge Landfill closure and Potsdam environmental remediation (i)		1,811				4,169				6,274				8,906
Cash outlays from acquisition activities (ii)		1,570				323				4,988				1,307
Post acquisition and development project capital expenditures (iii)		3,432				3,504				10,515				16,014
Waste USA Landfill phase VI capital expenditures (iv)		3,084				3,873				13,325				10,573
Adjusted Free Cash Flow	$	17,022			$	9,142			$	95,332			$	69,147

(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 the following costs required to achieve initial operating synergies: trucks, equipment and machinery; and facilities, land, IT infrastructure or related upgrades to 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 following capital expenditures required to achieve initial operating synergies: trucks, equipment and machinery; and facilities, land, IT infrastructure or related upgrades to 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.
