1. BASIS OF PRESENTATION

Casella Waste Systems, Inc. (“Parent”), a Delaware corporation, and its consolidated subsidiaries (collectively, “we”, “us” or “our”), is a regional, vertically integrated solid waste services company. We provide resource management expertise and services to residential, commercial, municipal, institutional and industrial customers, primarily in the areas of solid waste collection and disposal, transfer, recycling and organics services. We provide integrated solid waste services in seven states: Vermont, New Hampshire, New York, Massachusetts, Connecticut, Maine and Pennsylvania, with our headquarters located in Rutland, Vermont. We manage our solid waste operations on a geographic basis through 2two regional operating segments, the Eastern and Western regions, each of which provides a full range of solid waste services. We manage our resource-renewal operations through the Resource Solutions operating segment, which leverages our core competencies in materials processing, industrial recycling, organics and resource management service offerings to deliver a comprehensive solution for our larger commercial, municipal, institutional and industrial customers that have more diverse waste and recycling needs. Legal, tax, information technology, human resources, certain finance and accounting and other administrative functions are included in our Corporate Entities segment.

The accompanying unaudited consolidated financial statements, which include the accounts of the Parent and our wholly-owned subsidiaries, have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). All significant intercompany accounts and transactions are eliminated in consolidation. Investments in entities in which we do not have a controlling financial interest are accounted for under either the equity method or the cost method of accounting, as appropriate. Our significant accounting policies are more fully discussed in Item 8,8. "Financial Statements and Supplementary Data" of our Annual Report on Form 10-K for the fiscal year ended December 31, ~~2021~~2022 ("fiscal year ~~2021"~~2022"), which was filed with the SEC on February ~~18, 2022.~~17, 2023 ("2022 Form 10-K").

Preparation of our consolidated financial statements in accordance with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the accounting for and recognition and disclosure of assets, liabilities, equity, revenues and expenses. We must make these estimates and assumptions because certain information that we use is dependent on future events, cannot be calculated with a high degree of precision given the available data, or simply cannot be readily calculated. In the opinion of management, these consolidated financial statements include all adjustments, which include normal recurring and nonrecurring adjustments, necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented. The results for the three months ended March 31, ~~2022~~2023 may not be indicative of the results for any other interim period or the entire fiscal year. The consolidated financial statements presented herein should be read in conjunction with our audited consolidated financial statements included in our ~~Annual Report on~~2022 Form ~~10-K for fiscal year 2021.~~10-K.

When necessary, certain prior period amounts in the consolidated financial statements are conformed to current period presentation. This includes the presentation of certain adjustments to reconcile net income to net cash provided by operating activities, which have been reclassified within cash flows from operating activities.

We have evaluated subsequent events or transactions that have occurred after the consolidated balance sheet date of March 31, ~~2022~~2023 through the date of filing of the consolidated financial statements with the SEC on this Quarterly Report on Form 10-Q. ~~We have determined that there are~~Except as disclosed, no material subsequent events have occurred since March 31, 2023 through the date of this filing that would require recognition or disclosure in ~~this Quarterly Report on Form 10-Q.~~our consolidated financial statements.

We currently have interest rate derivative agreements with hedging relationships that reference ~~LIBOR.~~LIBOR, which is going to be discontinued effective July 1, 2023. This guidance provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. ~~We are currently assessing~~Effective the ~~provisions of~~three months ended March 31, 2023, we elected optional expedients under this guidance that provide temporary relief over contract modifications and reviewing and updating our existing contracts, as applicable, for transition or fallback language that specifies how a replacement rate for LIBOR will be identified. We are also no longer using LIBOR as ahedge accounting in order to maintain hedge effectiveness upon modifying contract terms related to reference rate ~~for any new contracts.

~~ASU No. 2021-08: Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (Topic 805)~~

Requires entities to apply ASC 606 to recognize and measure contract assets and contract liabilities in a business combination. This guidance improves comparability after the business combination by providing consistent recognition and measurement guidance for revenue contracts with customers acquired in a business combination and revenue contracts with customers not acquired in a business combination.

We have made in the past, and we may make in the future, acquisitions to densify existing operations, expand service areas, and grow services for our customers, and these acquisitions may include contract assets or contract liabilities. We do not expect that the adoption of this guidance will have a material impact on our consolidated financial statements and related disclosures. This guidance is effective January 1, 2023 with early adoption permitted.

Payments to customers that are not in exchange for a distinct good or service are recorded as a reduction of revenues. Rebates to certain customers associated with payments for recycled or organic materials that are received and subsequently processed and sold to other third-parties amounted to $6,629 in the three months ended March 31, 2023 and $3,794 in the three months ended March 31, ~~2022 and $1,568 in the three months ended March 31, 2021.~~2022. Rebates are generally recorded as a reduction of revenues upon the sale of such materials, or upon receipt of the recycled materials at our facilities. We did not record any revenues in the three months ended March 31, ~~2022~~2023 or March 31, ~~2021~~2022 from performance obligations satisfied in previous periods.

Contract receivables, which are included in Accounts receivable, net are recorded when billed or when related revenue is earned, if earlier, and represent claims against third-parties that will be settled in cash. Accounts receivable, net includes gross receivables from contracts of ~~$94,967~~$97,340 and ~~$89,232~~$102,234 as of March 31, ~~2022~~2023 and December 31, ~~2021,~~2022, respectively. Certain customers are billed in advance and, accordingly, recognition of the related revenues is deferred as a contract liability until the services are provided and control transferred to the customer. We recognized contract liabilities of ~~$5,500~~$4,146 and ~~$3,404~~$3,742 as of March 31, ~~2022~~2023 and December 31, ~~2021,~~2022, respectively. Due to the short term nature of advanced billings, substantially all of the deferred revenue recognized as a contract liability as of December 31, ~~2021~~2022 and December 31, ~~2020~~2021 was recognized as revenue during the three months ended March 31, ~~2022~~2023 and March 31, ~~2021,~~2022, respectively, when the services were performed.

~~4. BUSINESS COMBINATIONS~~

In the three months ended March 31, 2022, we acquired the following businesses: a full service solid-waste collection, recycling and hauling business in our Resource Solutions operating segment; 3 tuck-in solid waste collection businesses in our Western region; a portable toilets business in our Eastern region; and a scrap metal collection business whose assets are allocated between our Eastern region and Resource Solutions operating segments. In the three months ended March 31, 2021, we acquired 1 tuck-in solid waste collection business in our Western region.

The operating results of these businesses are included in the accompanying unaudited consolidated statements of operations from each date of acquisition, and the purchase price has been allocated to the net assets acquired based on fair values at each date of acquisition, with the residual amounts recorded as goodwill. Purchase price allocations are based on information existing at the acquisition dates or upon closing the transactions, including contingent consideration. Acquired intangible assets other than goodwill that are subject to amortization include customer relationships, trade names and covenants not-to-compete. Such assets are amortized over a four-year to ten-year period from the date of acquisition. All amounts recorded to goodwill are expected to be deductible for tax purposes.

6. ACCRUED FINAL CAPPING, CLOSURE AND POST CLOSURE

Accrued final capping, closure and post-closure costs include the current and non-current portion of costs associated with obligations for final capping, closure and post-closure of our landfills. We estimate our future final capping, closure and post-closure costs in order to determine the final capping, closure and post-closure expense per ton of waste placed into each landfill. The anticipated time frame for paying these costs varies based on the remaining useful life of each landfill as well as the duration of the post-closure monitoring period.

Financing Activities

In April 2023, we entered into a commitment letter with lenders to obtain secured bridge financing in an amount of up to $375,000, less the amount of any term loan A ("Term Loan A"), and received the commitment of certain commitment parties to fund up to $261,500 of a maximum of $400,000 Term Loan A, which may be a delayed draw, under our Amended and Restated Credit Agreement to fund, in conjunction with cash and cash equivalents and borrowings from our Revolving Credit Facility the purchase of the equity interests of four wholly owned subsidiaries of GFL Environmental ("GFL Subsidiaries"). On April 21, 2023, we entered into an equity purchase agreement with GFL Environmental Inc. to purchase 100% of the equity interests of the GFL Subsidiaries that operate solid waste collection, transfer and recycling operations in Pennsylvania, Maryland, and Delaware for approximately $525,000 in cash. The proposed acquisition includes nine hauling operations, one transfer station, and one material recovery facility. The acquisition is expected to close by the third quarter of the fiscal year ending December 31, 2023 ("fiscal year 2023"), subject to customary closing conditions, including regulatory approvals.

As of March 31, ~~2022,~~2023, we are party to ~~an amended~~the Amended and ~~restated credit agreement ("~~Restated Credit ~~Agreement"),~~Agreement, which provides for a $350,000 aggregate principal amount Term Loan Facility and a $300,000 Revolving Credit Facility, with a $75,000 sublimit for letters of credit. We have the right to request, at our discretion, an increase in the amount of loans under the Credit Facility by an aggregate amount of $125,000, subject to the terms and conditions set forth in the Amended and Restated Credit Agreement. The Credit Facility has a 5-year term that matures in December ~~2026~~2026. On February 9, 2023, we entered into first and ~~bears~~second amendments to the Amended and Restated Credit Agreement. The first amendment provides, commencing in the fiscal year ending December 31, 2024, the interest rate margin applied for drawn and undrawn amounts under the Amended and Restated Credit Agreement shall be separately adjusted based on our achievement of certain thresholds and targets on two sustainability related key performance indicator metrics during fiscal year 2023: (i) metric tons of solid waste materials reduced, reused or recycled through our direct operations or with third-parties in collaboration with customers; and (ii) our total recordable incident rate. The second amendment provides that loans under the Amended and Restated Credit Agreement shall bear interest, at a rate of LIBOR plus 1.375% per annum, which will be reduced to a rate of LIBOR plus as low as 1.125% upon us reaching a consolidated net leverage ratio of less than 2.25x. The Credit Facility contains customary benchmark replacement provisions pursuant to which, upon certain triggering events, the LIBOR benchmark used to calculate the LIBOR rate will be replaced withour election, at Term SOFR, including a secured overnight financing rate adjustment of 10 basis points, or at a base rate, in each case, plus an applicable interest rate margin based on consolidated net leverage ratio, and plus or minus any sustainability rate adjustment. Unless loans are made as ~~adjusted, on~~or converted to base rate loans, loans under the ~~terms~~Amended and ~~conditions~~Restated Credit Agreement will bear interest at Term SOFR, including a secured overnight financing rate adjustment of 10 basis points, plus a margin based upon our consolidated net leverage ratio in the range of 1.125% to 2.125% per annum, plus a sustainability adjustment of up to positive or negative 4.0 basis point per annum. A commitment fee will be charged on undrawn amounts at a rate of Term SOFR, plus a margin based upon our consolidated net leverage ratio in the range of 0.20% to 0.40% per annum, plus a sustainability adjustment of up to positive or negative 1.0 basis points per annum. We are also required to pay a fronting fee for each letter of credit of 0.25% per annum. Interest under the Amended and Restated Credit ~~Facility.~~Agreement is subject to increase by 2.00% per annum during the continuance of a payment default and may be subject to increase by 2.00% per annum during the continuance of any other event of default. The Credit Facility is guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries and secured by substantially all of our assets. As of March 31, ~~2022,~~2023, further advances were available under the Revolving Credit Facility in the amount of ~~$252,805.~~$272,267. The available amount is net of outstanding irrevocable letters of credit totaling ~~$28,195,~~$27,733, and as of March 31, ~~2022~~2023 no amount had been drawn.

Our strategy to reduce exposure to interest rate risk involves entering into interest rate derivative agreements to hedge against adverse movements in interest rates related to the variable rate portion of our long-term debt. We have designated these derivative instruments as highly effective cash flow hedges, and therefore the change in their fair value is recorded in ~~our~~ stockholders’ equity as a component of accumulated other comprehensive income, ~~(loss),~~ net of tax and included in interest expense at the same time as interest expense is affected by the hedged transactions. Differences paid or received over the life of the agreements are recorded as additions to or reductions of interest expense on the underlying debt and included in cash flows from operating activities.

As of both March 31, ~~2022~~2023 and December 31, ~~2021,~~2022, our active interest rate derivative agreements had a total notional ~~amounts~~amount of ~~$195,000.~~$190,000. According to the terms of the agreements, we receive interest based on the 1-month LIBOR index, in some instances restricted by a 0.0% floor, and pay interest at a weighted average rate of approximately ~~2.48%~~2.20%. The agreements mature between ~~June 2022~~May 2023 and ~~February~~June 2027.

~~Additionally, as~~As of March 31, ~~2022 and December 31, 2021,~~2023, we ~~have~~had outstanding forward starting interest rate derivative agreements with a total notional ~~amounts~~amount of $60,000, ~~and $85,000, respectively, after considering any forward starting interest rate derivative agreements that have become effective in the current period. According to the terms~~$20,000 of ~~the agreements,~~which we will receive interest based on the 1-month LIBOR index, restricted by a 0.0% floor, and $40,000 of which we will receive interest based on Term SOFR, restricted by a 0.0% floor. The agreements mature in May 2028 and will pay interest at a weighted average interest rate of ~~approximately 1.44%~~2.8%. ~~The agreements mature between June 2027 and May 2028.~~

As of December 31, 2022, we had a forward starting interest rate derivative agreement with a notional amount of $20,000.

8. COMMITMENTS AND CONTINGENCIES

In the ordinary course of our business and as a result of the extensive governmental regulation of the solid waste industry, we are subject to various judicial and administrative proceedings involving state and local agencies. In these proceedings, an agency may seek to impose fines or to revoke or deny renewal of an operating permit held by us. From time to time, we may also be subject to actions brought by special interest or other groups, adjacent landowners or residents in connection with the permitting and licensing of landfills and transfer stations, or allegations of environmental damage or violations of the permits and licenses pursuant to which we operate. In addition, we may be named defendants in various claims and suits pending for alleged damages to persons and property, alleged violations of certain laws and alleged liabilities arising out of matters occurring during the ordinary operation of a waste management business. The plaintiffs in some actions seek unspecified damages or injunctive relief, or both. These actions fall within various procedural stages at any point in time, and some are covered in part by insurance.

In accordance with FASB ASC 450 - Contingencies, we accrue for legal proceedings, inclusive of legal costs, when losses become probable and reasonably estimable. We have recorded an aggregate accrual of ~~$1,241~~$821 relating to our outstanding legal proceedings as of March 31, ~~2022.~~2023. As of the end of each applicable reporting period, we review each of our legal proceedings to determine whether it is probable, reasonably possible or remote that a liability has been incurred and, if it is at least reasonably possible, whether a range of loss can be reasonably estimated under the provisions of FASB ASC 450-20. In instances where we determine that a loss is probable and we can reasonably estimate a range of loss we may incur with respect to such a matter, we record an accrual for the amount within the range that constitutes our best estimate of the possible loss. If we are able to reasonably estimate a range, but no amount within the range appears to be a better estimate than any other, we record an accrual in the amount that is the low end of such range. When a loss is reasonably possible, but not probable, we will

not record an accrual, but we will disclose our estimate of the possible range of loss where such estimate can be made in accordance with FASB ASC 450-20. We disclose outstanding matters that we believe could have a material adverse effect on our financial condition, results of operations or cash flows.

North Country Environmental Services Expansion Permit

On October 9, 2020, our subsidiary, North Country Environmental Services, Inc. ("NCES"), received a Type I-A Permit Modification ~~(the "Permit"~~("Permit") from the New Hampshire Department of Environmental Services ("DES") for Expansion in the Stage VI area of the NCES landfill located in Bethlehem, New Hampshire. On

November 9, 2020, the Conservation Law Foundation ("CLF") filed an appeal of the Permit to the New Hampshire Waste Management Council ~~(the “Council”~~(“Council”) on the grounds it failed to meet the public benefit criteria. DES defended its decision in the appeal, and NCES also participated as the permittee seeking to defend its permit on appeal.

Throughout 2021 and early 2022 a number of motions were filed by both NCES and CLF with the Council and in February 2022 the Council held a hearing on the CLF appeal. The Council ruled in favor of NCES on all claims set forth in CLF’s appeal. On ~~January 19, 2021,~~May 11, 2022, the Council’s Hearing Officer issued an Order denying all of CLF’s arguments on appeal, with the exception of one: the Hearing Officer held that based on his interpretation of the relevant statute, the public benefit determination made by DES in issuing the Permit to NCES was unlawful (the “Hearing Officer’s Order”). The Hearing Officer remanded the Permit to DES with regard to this determination.

DES filed a Motion for Reconsideration on May 31, 2022, and NCES filed a Motion for Rehearing on June 10, 2022. The Hearing Officer denied both motions in separate orders dated November 3, 2022, issued contemporaneously with rulings on three other post-hearing motions. NCES filed a Motion for Rehearing of two of the three post-hearing motion rulings on December 5, 2023, and this Motion remains pending.

DES and NCES appealed the Hearing Officer’s Order to the New Hampshire Supreme Court (“Supreme Court”). On December 23, 2022, CLF filed a ~~Complaint~~Motion for ~~Injunctive Relief with~~Summary Affirmance of the ~~Grafton Superior~~Hearing Officer’s Order, to which NCES and DES each filed an Objection on January 6, 2023. On January 30, 2023 the Supreme Court ~~to enjoin~~issued an Order accepting and consolidating the DES and NCES ~~from accepting waste pursuant to the new Permit until such a time as CLF has exhausted its appeal rights. A hearing on the Complaint~~appeals and denying CLF’s Motion for Injunctive Relief was held on March 10, 2021; the Grafton Superior Court denied the motion on May 14, 2021. CLF did not appeal this decision. The Council denied NCES’s Motion to Dismiss CLF’s appeal for lack of standing by Order dated March 17, 2021.Summary Affirmance. On January 31, 2023, NCES filed a Motion to ~~Reconsider~~Stay the Supreme Court appeals pending the outcome of the Superior Court Open Meeting Law Proceeding discussed below. On February 9, 2023, CLF filed an Objection to the Motion to Stay. The Supreme Court denied the Motion to Stay on February 22, 2023. On March ~~26, 2021, which was denied by~~2, 2023, the Supreme Court ordered the Council to prepare and file the record of the proceedings below by May 1, 2023. Once the record is filed, the Supreme Court will issue a briefing schedule.

On December 14, 2022, NCES filed an action against the Council in Merrimack Superior Court (“Superior Court”) seeking to invalidate the Hearing Officer’s Order as having been adopted in violation of New Hampshire’s statute governing access to public records and meetings (“Open Meeting Law Proceeding”), in that the Council did not hold a public meeting to deliberate on ~~May 11, 2021. A prehearing conference was held and a schedule for~~ the ~~case was established on June 8, 2021. NCES~~Hearing Officer’s Order prior to issuance. The Council filed a Motion to Dismiss on January 17, 2023 to which NCES filed a Summary Objection on January 18, 2023, followed by a supplemental Objection filed on February 6, 2023. Following a hearing on the merits before the Superior Court on January 18, 2023, the Superior Court ordered that NCES pursue a stay of the appeal ~~on June 30, 2021.~~of the Hearing Officer’s Order before the Supreme Court, and that the Superior Court would defer further ruling in the Open Meeting Law Proceeding pending a determination of whether the appeal before the Supreme Court would be stayed. On July 16, 2021, CLF filed its objection to the Motion to Dismiss, and NCES filed its reply on July 26, 2021. The Council issued an Order on September 3, 2021 granting NCES’s Motion to Dismiss, in part.January 20, 2023, CLF filed a Motion ~~for Reconsideration on September 23, 2021, and~~to Intervene in the Open Meeting Law Proceeding. NCES filed ~~its objection~~an Objection on ~~September 28, 2021~~February 8, 2023, and CLF filed a ~~reply~~Reply in Support of Motion to Intervene on February 17, 2023. The Council filed a Supplemental Memorandum of Law on February 17, 2023, to which NCES filed a Response on February 24, 2023. On April 5, 2023, the Superior Court issued an Order granting the Council’s Motion to Dismiss, which was appealed by NCES to the Supreme Court on April 18, 2023.

On September ~~30, 2021. CLF’s Motion~~20, 2022, NCES and our subsidiary, Granite State Landfill, LLC, filed a Petition for ~~Reconsideration was granted~~Declaratory Judgment ("Petition") in the Superior Court seeking a determination of the meaning and constitutionality of New Hampshire’s public benefit requirement. The Petition asks the court to construe the same statute on ~~November 19, 2021, and its dismissed claims reinstated.~~which the Hearing Officer relied in the Hearing Officer’s Order. On ~~January 14,~~September 21, 2022, NCES filed a Motion ~~in Limine seeking~~ to ~~exclude from evidence four potential evidentiary items on~~Stay the ~~basis~~Council proceedings pending resolution of the Petition action. DES assented to the relief sought by that ~~those items were either not directly related, or were not included in CLF’s Notice of Appeal.

On October 3, 2022, NCES filed a Motion for Leave to File Reply together with its Reply to CLF’s Objection to Motion to Stay. The Hearing Officer denied the Motion to Stay by Order dated November 3, 2022. On December 19, 2022, CLF moved to intervene in the Petition proceeding before the Superior Court, and NCES filed an Objection on January 4, 2023.

Environmental Remediation Liabilities

We are subject to liability for environmental damage, including personal injury and property damage, that our solid waste, recycling and power generation facilities may cause to neighboring property owners, particularly as a result of the contamination of drinking water sources or soil, possibly including damage resulting from conditions that existed before we acquired the facilities. We may also be subject to liability for similar claims arising from off-site environmental contamination caused by pollutants or hazardous substances if we or our predecessors arrange or arranged to transport, treat or dispose of those materials.

We accrue for costs associated with environmental remediation obligations when such costs become both probable and reasonably estimable. Determining the method and ultimate cost of remediation requires that a number of assumptions be made. There can sometimes be a range of reasonable estimates of the costs associated with remediation of a site. In these cases, we use the amount within the range that constitutes our best estimate. In the early stages of the remediation process, particular components of the overall liability may not be reasonably estimable; in this instance we use the components of the liability that can be reasonably estimated as a surrogate for the liability. It is reasonably possible that we will need to adjust the liabilities recorded for remediation to reflect the effects of new or additional information, to the extent such information impacts the costs, timing or duration of the required actions. Future changes in our estimates of the cost, timing or duration of the required actions could have a material adverse effect on our consolidated financial position, results of operations and cash flows. We disclose outstanding environmental remediation matters that remain unsettled or are settled in the reporting period that we believe could have a material adverse effect on our financial condition, results of operations or cash flows.

We inflate the estimated costs in current dollars to the expected time of payment and discount the total cost to present value using a risk-free interest rate. The ~~weighted average~~ risk-free interest ~~rate~~rates associated with our environmental remediation liabilities as of March 31, ~~2022 ranges~~2023 range between 1.5% and ~~2.6%~~4.1%. A summary of the changes to the aggregate environmental remediation liabilities for the three months ended March 31, ~~2022~~2023 and ~~2021~~2022 follows:

Obligations settled (1)

(1)May include amounts paid and amounts that are being processed through accounts payable as a part of our disbursement cycle.

9. STOCKHOLDERS' EQUITY

Stock Based Compensation

Shares Available For Issuance

In the fiscal year ended December 31, 2016, we adopted the 2016 Incentive Plan (“2016 Plan”). Under the 2016 Plan, we may grant awards up to an aggregate amount of shares equal to the sum of: (i) 2,250 shares of Class A common stock (subject to adjustment in the event of stock splits and other similar events), plus (ii) such additional number of shares of Class A common stock (up to 2,723 shares) as is equal to the sum of the number of shares of Class A common stock that remained available for grant under the 2006 Stock Incentive Plan (“2006 Plan”) immediately prior to the expiration of the 2006 Plan and the number of shares of Class A common stock subject to awards granted under the 2006 Plan that expire, terminate or are otherwise surrendered, canceled, forfeited or repurchased by us. As of March 31, ~~2022,~~2023, there were ~~811~~649 Class A common stock equivalents available for future grant under the 2016 Plan.

Stock options are granted at a price equal to the prevailing fair value of our Class A common stock at the date of grant. Generally, stock options granted have a term not to exceed ten years and vest over a one-year to ~~four-year~~five-year period from the date of grant.

The fair value of each stock option granted is estimated using a Black-Scholes option-pricing model, which requires extensive use of accounting judgment and financial estimation, including estimates of the expected term stock option holders will retain their vested stock options before exercising them and the estimated volatility of our Class A common stock price over the expected term.

A summary of stock option activity follows:


		Stock Options	Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (years)	Aggregate Intrinsic Value			Stock Options	Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (years)	Aggregate Intrinsic Value

Stock-based compensation expense related to stock options was $123 during the three months ended March 31, 2023, as compared to $16 during the three months ended March 31, 2022. ~~We did not record any stock-based compensation expense for stock options during the three months ended March 31, 2021.~~ As of March 31, ~~2022,~~2023, we had ~~$155~~$1,975 of unrecognized stock-based compensation expense related to outstanding stock options to be recognized over a weighted average period of ~~2.3~~4.2 years.

During the three months ended March 31, ~~2022,~~2023, the aggregate intrinsic value of stock options exercised was ~~$311.~~zero dollars.

Restricted stock awards, restricted stock units and performance stock units, with the exception of market-based performance stock units, are granted at a price equal to the fair value of our Class A common stock at the date of grant. The fair value of each market-based performance stock unit is estimated using a Monte Carlo pricing model, which requires extensive use of accounting judgment and financial estimation, including the estimated share price appreciation plus, if applicable, the value of dividends of our Class A common stock as compared to the Russell 2000 Index over the requisite service period.

Generally, restricted stock awards granted to non-employee directors vest incrementally over a three year period beginning on the first anniversary of the date of grant. Restricted stock units granted to non-employee directors vest in full on the first anniversary of the grant date. Restricted stock units granted to employees vest incrementally over an identified service period, typically three years, beginning on the grant date based on continued employment. Performance stock units granted to employees, including market-based performance stock units, vest at a future date following the grant date and are based on the attainment of performance targets and market achievements, as applicable.

A summary of restricted stock award, restricted stock unit and performance stock unit activity follows:


		Restricted Stock, Restricted Stock Units, and Performance Stock Units (1)	Weighted Average Grant Date Fair Value		Weighted Average Remaining Contractual Term (years)	Aggregate Intrinsic Value			Restricted Stock Awards, Restricted Stock Units, and Performance Stock Units (1)	Weighted Average Grant Date Fair Value		Weighted Average Remaining Contractual Term (years)	Aggregate Intrinsic Value

(1)Market-based performance stock unit grants are included at the 100% attainment level. Attainment of the maximum performance targets and market achievements would result in the issuance of an additional ~~221~~159 shares of Class A common stock currently included in unvested.

Stock-based compensation expense related to restricted stock awards, restricted stock units and performance stock units was $1,762 during the three months ended March 31, 2023, as compared to $2,151 during the three months ended March 31, ~~2022, as compared to $2,884 during the three months ended March 31, 2021.~~2022.

During the three months ended March 31, ~~2022,~~2023, the total fair value of other stock awards vested was ~~$4,545.~~$3,962.

As of March 31, ~~2022,~~2023, total unrecognized stock-based compensation expense related to outstanding restricted stock awards was ~~$71,~~$26, which will be recognized over a weighted average period of ~~1.7 years.~~1.0 year. As of March 31, ~~2022,~~2023, total unrecognized stock-based compensation expense related to outstanding restricted stock units was ~~$6,015,~~$6,008, which will be recognized over a weighted average period of ~~2.2~~2.3 years. As of March 31, ~~2022,~~2023, total expected unrecognized stock-based compensation expense related to outstanding performance stock units was ~~$9,779~~$7,990 to be recognized over a weighted average period of ~~2.0~~2.1 years.

The weighted average fair value of market-based performance stock units granted during the three months ended March 31, 2023 was $83.16 per award, which was calculated using a Monte Carlo pricing model assuming a risk-free interest rate of 4.31% and an expected volatility of 34.9% assuming no expected dividend yield. Risk-free interest rate is based on the U.S. Treasury yield curve for the expected service period of the award. Expected volatility is calculated using the daily volatility of our Class A common stock over the expected service period of the award.

The Monte Carlo pricing model requires extensive use of accounting judgment and financial estimation. Application of alternative assumptions could produce significantly different estimates of the fair value of stock-based compensation and consequently, the related amounts recognized in the consolidated statements of operations.

We also recorded ~~$73~~$90 of stock-based compensation expense related to our Amended and Restated 1997 Employee Stock Purchase Plan during the three months ended March 31, ~~2022,~~2023, as compared to ~~$57~~$73 during the three months ended March 31, ~~2021.~~

10. EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated based on the combined weighted average number of common shares and potentially dilutive shares, which include the assumed exercise of employee stock options, unvested restricted stock awards, unvested restricted stock units and unvested performance stock units, including market-based performance units based on the expected achievement of performance targets. In computing diluted earnings per share, we utilize the treasury stock method.

A summary of the numerator and denominators used in the computation of earnings per share follows:

11. OTHER ITEMS AND CHARGES

Expense from Acquisition Activities

In the three months ended March 31, ~~2022~~2023, and ~~2021,~~2022, we recorded charges of ~~$2,043~~$2,863 and ~~$414,~~$2,043, respectively, comprised primarily of legal, consulting and other similar costs associated with due diligence and the acquisition and integration of acquired businesses or select development projects.

12. FAIR VALUE OF FINANCIAL INSTRUMENTS

We use a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. These tiers include: Level 1, defined as quoted market prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; and Level 3, defined as unobservable inputs that are not corroborated by market data.

We use valuation techniques that maximize the use of market prices and observable inputs and minimize the use of unobservable inputs. In measuring the fair value of our financial assets and liabilities, we rely on market data or assumptions that we believe market participants would use in pricing an asset or a liability.

Assets and Liabilities Accounted for at Fair Value

Our financial instruments include cash and cash equivalents, accounts receivable, restricted investment securities held in trust on deposit with various banks as collateral for our obligations relative to our landfill final capping, closure and post-closure costs, interest rate derivatives, contingent consideration related to acquisitions, trade payables and debt. The carrying values of cash and cash equivalents, accounts receivable and trade payables approximate their respective fair values due to their short-term nature. The fair value of restricted investment securities held in trust, which are valued using quoted market prices, are included as restricted assets in the Level 1 tier below. The fair value of the interest rate derivatives included in the Level 2 tier below is calculated using discounted cash flow valuation methodologies based upon ~~the~~ one-month LIBOR or Term SOFR, as applicable, yield curves that are observable at commonly quoted intervals for the full term of the swaps. The fair value of contingent consideration - acquisition included in the Level 3 tier below is calculated using a discounted cash flow valuation methodology based upon a probability-weighted analysis of a success payment related to the potential attainment of a transfer station permit expansion. We recognize all derivatives accounted for on the balance sheet at fair value.

Recurring Fair Value Measurements

Summaries of our financial assets and liabilities that are measured at fair value on a recurring basis follow:


		Fair Value Measurement at March 31, 2022 Using:							Fair Value Measurement at March 31, 2023 Using:
		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)			Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

As of March 31, ~~2022,~~2023, the fair value of our fixed rate debt, including our FAME Bonds 2005R-3, FAME Bonds 2015R-1, FAME Bonds 2015R-2, Vermont Bonds 2013, Vermont Bonds 2022A-1, New York Bonds 2014R-1, New York Bonds 2014R-2, New York Bonds 2020 and New Hampshire Bonds (collectively, the "Industrial Revenue Bonds") was approximately ~~$165,864~~$186,760 and the carrying value was ~~$162,000.~~$197,000. The fair value of the ~~FAME Bonds 2005R-3, the FAME Bonds 2015R-1, the FAME Bonds 2015R-2, the Vermont Bonds, the New York Bonds 2014R-1, the New York Bonds 2014R-2, New York Bonds 2020 and the New Hampshire~~Industrial Revenue Bonds is considered to be Level 2 within the fair value hierarchy as the fair value is determined using market approach pricing provided by a third-party that utilizes pricing models and pricing systems, mathematical tools and judgment to determine the evaluated price for the security based on the market information of each of the bonds or securities with similar characteristics.

As of March 31, ~~2022,~~2023, the carrying value of our Term Loan Facility was $350,000 and the carrying value of our Revolving Credit Facility was ~~$19,000.~~zero dollars. Their fair values are based on current borrowing rates for similar types of borrowing arrangements, or Level 2 inputs, and approximate their carrying values.

Although we have determined the estimated fair value amounts of ~~FAME Bonds 2005R-3, FAME Bonds 2015R-1, FAME Bonds 2015R-2, Vermont Bonds, New York Bonds 2014R-1, New York Bonds 2014R-2, New York Bonds 2020 and New Hampshire~~the Industrial Revenue Bonds using available market information and commonly accepted valuation methodologies, a change in available market information, and/or the use of different assumptions and/or estimation methodologies could have a material effect on the estimated fair values. These amounts have not been revalued, and current estimates of fair value could differ significantly from the amounts presented.

13. SEGMENT REPORTING

We report selected information about our reportable operating segments in a manner consistent with that used for internal management reporting. We classify our solid waste operations on a geographic basis through regional operating segments, our ~~Western~~Eastern and ~~Eastern~~Western regions. Revenues associated with our solid waste operations are derived mainly from solid waste collection ~~transfer, transportation~~ and disposal services, including landfill, transfer station and transportation services, landfill gas-to-energy ~~processing,~~services, and ~~recycling~~processing services in the northeastern United States. Our Resource Solutions operating segment leverages our core competencies in materials processing, industrial recycling, organics and resource management service offerings to deliver a comprehensive solution for our larger commercial, municipal, institutional and industrial customers that have more diverse waste and recycling needs. Revenues associated with our Resource Solutions operations are ~~derived from two lines-of-service:~~comprised of processing services and ~~non-processing.~~services provided by our National Accounts business. Revenues from processing services are derived from ~~municipalities and~~ customers in the form of processing fees, tipping fees, commodity sales, and organic material sales. Revenues from ~~non-processing services~~our National Accounts business are derived from brokerage services and overall resource management services providing a wide range of environmental services and ~~zero waste~~resource management solutions to large and complex organizations, as well as traditional collection, disposal and recycling services provided to large account multi-site customers. Legal, tax, information technology, human resources, certain finance and accounting and other administrative functions are included in our Corporate Entities segment, which is not a reportable operating segment. Corporate Entities results reflect those costs not allocated to our reportable operating segments.

Casella Waste Systems, Inc., a Delaware corporation, and its ~~wholly-owned~~consolidated subsidiaries (collectively, “we”, “us” or “our”), is a regional, vertically integrated solid waste services company. We provide resource management expertise and services to residential, commercial, municipal, institutional and industrial customers, primarily in the areas of solid waste collection and disposal, transfer, recycling and organics services. We provide integrated solid waste services in seven states: Vermont, New Hampshire, New York, Massachusetts, Connecticut, Maine and Pennsylvania, with our headquarters located in Rutland, Vermont. We manage our solid waste operations on a geographic basis through two regional operating segments, the Eastern and Western regions, each of which provides a full range of solid waste services. We manage our resource-renewal operations through the Resource Solutions operating segment, which leverages our core competencies in materials processing, industrial recycling, organics and resource management service offerings to deliver a comprehensive solution for our larger commercial, municipal, institutional and industrial customers that have more diverse waste and recycling needs. Our Resources Solutions operations consist of two lines-of-service: processing and non-processing. Processing services consist of the receipt of recycled, sludge or other organic materials at one of our materials recovery, processing or disposal facilities, where it is then sorted, mixed and/or processed, and then disposed of or sold. Non-processing services consist of brokerage services and overall resource management services, which provide a wide range of environmental services and zero waste solutions to large and complex organizations, as well as traditional collection, disposal and recycling services provided to large account multi-site customers.

As of April 15, ~~2022,~~2023, we owned and/or operated 4950 solid waste collection operations, 6366 transfer stations, 2526 recycling facilities, eight Subtitle D landfills, three landfill gas-to-energy facilities and one landfill permitted to accept construction and demolition (“C&D”) materials. We also housed two landfill gas-to-energy facilities, which are owned and operated by third parties at landfills we owned and/or operated.

Results of Operations

We manage our solid waste operations, which include a full range of solid waste services, on a geographic basis through two regional operating segments, which we designate as the Eastern and Western regions. Revenues in our Eastern and Western regions consist primarily of fees charged to customers for solid waste collection and disposal services, including landfill, transfer station and transportation, landfill gas-to-energy, and processing services. We derive a substantial portion of our collection revenues from commercial, industrial and municipal services that are generally performed under service agreements or pursuant to contracts with municipalities. The majority of our residential collection services are performed on a subscription basis with individual ~~households.~~property owners or occupants. Landfill and transfer customers are charged a tipping fee on a per ton basis for disposing of their solid waste at our disposal facilities and transfer stations. We also generate and sell electricity at certain of our landfill facilities. We manage our resource-renewal operations through the Resource Solutions operating segment, which includes processing services, and non-processing ~~services.~~services, which we now refer to as our National Accounts business. Revenues from processing services are derived from ~~municipalities and~~ customers in the form of processing fees, tipping fees, and commodity sales, primarily comprised of newspaper, corrugated containers, plastics, ferrous and aluminum, and organic materials such as our earthlife® soils products including fertilizers, composts and mulches. Revenues from ~~non-processing services~~our National Accounts business are derived from brokerage services and overall resource management services providing a wide range of environmental services and ~~zero waste~~resource management solutions to large and complex organizations, as well as traditional collection, disposal and recycling services provided to large account multi-site customers.

~~Solid waste revenues~~

The price change component in quarterly solid waste revenues growth from the prior year period is the result of the following:

•$~~6.3~~10.7 million from favorable collection pricing; and

•$~~1.5~~4.0 million from favorable disposal pricing associated with our landfills, transfer stations and, ~~transfer stations.~~to a lesser extent, transportation services.

The volume change component in quarterly solid waste revenues growth from the prior year period is the result of the following:

•$~~0.5 million from higher collection volumes as a result of increased activity and new customer acquisition; and~~

•~~$0.3~~2.8 million from higher disposal volumes (of which ~~$0.3 million relates to higher transportation volumes and $0.3~~$1.7 million relates to higher transfer station volumes ~~partially offset by $(0.3)~~and $1.1 million ~~that~~ relates to ~~lower third-party~~higher landfill volumes); partially offset by

•$~~(0.1)~~(2.2) million from lower ~~processing volumes.~~collection volumes primarily in our Western region associated with higher customer churn due to increased pricing, higher fees charged to additional customers and customer deselection.

Surcharges and other fees.

The surcharges and other fees change component in quarterly solid waste revenues growth from the prior year period is the result of higher energy and environmental fee ("E&E Fee(s)") revenues onand higher sustainability recycling adjustment fee ("SRA Fee(s)") revenues. Higher E&E Fee revenues associated with our fuel cost recovery program were a result of higher diesel fuel prices ~~partially offset by~~and a higher overall customer participation rate. Higher SRA Fee revenues were a result of lower ~~sustainability recycling adjustment fees ("SRA Fee") on higher~~ recycled commodity ~~prices.~~prices in the quarter and a higher overall customer participation rate. See Item 3. "Quantitative and Qualitative Disclosures about Market Risk" included in this Quarterly Report on Form 10-Q for additional information regarding our E&E Fee and SRA Fee.

Commodity price and volume.

The commodity price and volume change component in quarterly solid waste revenues growth from the prior year period is primarily the result of ~~$1.3 million primarily from favorable~~lower landfill gas-to-energy volumes and unfavorable commodity and energy pricing ~~and $0.3 million from higher landfill gas-to-energy and commodity processing volumes.~~in our Western region.

The acquisitions change component in quarterly solid waste revenues growth from the prior year period is primarily the result of ~~increased acquisition activity in line with our growth strategy, including the following:~~

•the timing and acquisition of six businesses in the three months ended March 31, 2022: a full service solid-waste collection, recycling and hauling business in our Resource Solutions operating segment; three tuck-in solid waste collection businesses in our Western region; a portable toilets business in our Eastern region; and a scrap metal collection business whose assets are allocated between our Eastern region and Resource Solutions operating segments; and

•the timing and acquisition of ten businesses within our Western region operating segment in ~~the~~line with our growth strategy in fiscal year ended December 31, 2021: a residential, commercial and roll-off collection business in eastern Connecticut that operates a rail-served C&D processing and waste transfer facility, a waste transfer station, a single-stream recycling facility, and several other recycling operations whose assets and liabilities are allocated between our Eastern region and Resource Solutions operating segments; a solid-waste collection business that operates a waste transfer station, a septic and portable toilet business, and two tuck-in solid-waste collection businesses in our Eastern region; and a solid-waste transfer station business, a waste composting and food-scrap hauling business, a solid-waste collection business that operates a waste transfer station, and two tuck-in solid-waste collection businesses in our Western region.2022.

Resource Solutions revenues

The change component in quarterly ~~resource solutions~~Resource Solutions revenues growth of ~~$15.4~~$0.9 million from the prior year period is the result of the following:

•$~~9.3~~4.8 million from ~~acquisition activity;~~higher processing volumes mainly driven by higher recycled commodity volumes;

•$~~3.4~~4.5 million from higher ~~non-processing~~ revenues associated with our National Accounts business due to ~~higher~~increased volumes on organic business growth, favorable pricing and ~~favorable pricing;~~

•~~$2.2 million from the favorable impact of commodity pricing in the marketplace (not including the negative impact of lower intercompany tipping fees that were reduced due to higher commodity pricing);~~increased fees; and

~~Labor and related benefit~~Fuel costs ~~increased $8.6 million quarterly, while increasing 100 basis points~~remained flat as a percentage of revenues, due primarily to wage inflation in our markets and increased overtime on higher solid waste volumes associated with an increased demand for services and acquisition activity, higher health insurance costs and higher workers compensation costs on claim activity.

~~Maintenance and repair costs increased $7.3 million quarterly,~~ while increasing ~~10 basis points as a percentage of revenues, due~~in aggregate dollars primarily ~~to higher fleet, facility and container maintenance costs associated with inflation, acquisition activity, and an increased demand for services.~~

~~Fuel costs increased $4.3 million quarterly, while increasing 130 basis points as a percentage of revenues,~~ due to higher diesel fuel prices and higher volumes driven by ~~acquisition activity~~acquisition-related growth in our Western region and anto a lesser extent, organic business growth.

The most significant items impacting the changes in our general and administration expenses during the three months ended March 31, 2023 and 2022 are summarized below:

•Labor costs decreased as a percentage of revenues, while increasing in aggregate dollars primarily ~~attributed~~due to ~~increased overhead costs associated with wage inflation and~~ business growth and wage inflation; partially offset by lower equity compensation ~~costs and lower~~costs;

•Other costs increased in aggregate dollars primarily due to inflationary pressures and an increase in general overhead costs to support business growth.

Depreciation and Amortization

Depreciation and amortization expense includes: (i) depreciation of property and equipment (including assets recorded for finance leases) on a straight-line basis over the estimated useful lives of the assets; (ii) amortization of landfill costs (including those costs incurred and all estimated future costs for landfill development and construction, along with asset retirement costs arising from closure and post-closure obligations) on a units-of-consumption method as landfill airspace is consumed over the total estimated remaining capacity of a site, which includes both permitted capacity and unpermitted expansion capacity that meets certain criteria for amortization purposes, and amortization of landfill asset retirement costs arising from final capping obligations on a units-of-consumption method as airspace is consumed over the estimated capacity associated with each final capping event; and (iii) amortization of intangible assets with a definite life, ~~using either an~~based on the economic benefit provided, ~~approach~~ or ~~on a~~using the sum of years digits or straight-line ~~basis~~methods over the definitive terms of the related agreements.

Expense from Acquisition Activities

In the three months ended March 31, ~~2022~~2023 and ~~2021,~~2022, we recorded charges of ~~$2.0~~$2.9 million and ~~$0.4~~$2.0 million, respectively, comprised primarily of legal, consulting and other similar costs associated with due diligence and the acquisition and integration of acquired businesses or select development projects.

Other Expenses

Interest Expense, net

Our interest expense, net ~~decreased $(0.2)~~increased $1.1 million ~~quarterly~~in the three months ended March 31, 2023 from the prior year period primarily due ~~primarily~~ to ~~lower average~~rising interest rates ~~on our debt associated with a lower interest rate spread associated with our amended~~ and ~~restated credit agreement ("Credit Agreement"), partially offset by~~ higher average debt balances associated with ~~borrowings against our amended and restated revolving credit facility ("Revolving Credit Facility").~~the issuance in June 2022 of $35.0 million aggregate principal amount of Vermont Economic Development Authority Solid Waste Disposal Long-Term Revenue Bonds Series 2022A-1.

Provision for Income Taxes

Our provision for income taxes decreased ~~$(1.5)~~$(0.2) million ~~quarterly as compared to~~in the ~~same period in~~three months ended March 31, 2023 from the prior year ~~primarily due to the lower~~period. The provision for income ~~from operations and the difference~~taxes in the ~~one-time adjustments for the tax benefit on equity compensation awards between the periods.~~three months ended March 31, 2023 included $0.5 million of current income taxes and $0.3 million of deferred income taxes. The provision for income taxes in the three months ended March 31, 2022 included $0.5 million of current income taxes and $0.5 million of deferred income taxes. ~~For~~The effective rate before discrete items for the fiscal year ending December 31, 2023 ("fiscal year 2023") is 30% and is computed based on the statutory rate of 21% adjusted primarily for state taxes and nondeductible officer compensation. The discrete items include equity compensation and a portion of equity compensation disallowed in 162(m). The equity compensation deduction is taken into account in the three months ended March 31, ~~2021,~~2023 due to the ~~provision included~~timing of bonuses and equity awards.Where the long-term trend of the stock price underlying the equity compensation has been increasing, this creates a ~~$(0.1) million current income~~larger deduction for tax, ~~benefit and $2.3 million of deferred income taxes.~~which reduces the effective rate for the three months ended March 31, 2023. The effective rate for the three months ended March 31, 2023 is 18.2% which is consistent with the same period in the prior year.For the period ending March 31, 2022 the effective rate was 31%, before the one-time adjustments primarily related to tax effects of accumulated other comprehensive losses and equity compensation, and is computed based on the statutory rate of 21%, adjusted primarily for state taxes and nondeductible officer compensation.18.6%.

On December 22, 2017, the Tax Cuts and Jobs Act (the ~~“TCJ Act”~~“TCJA”) was enacted. The ~~TCJ Act~~TCJA significantly changed U.S. corporate income tax laws by, among other things, changing carryforward rules for net operating losses. ~~Our $52.4 million in~~Under the Internal Revenue Code, as amended by the TCJA, federal net operating loss carryforwards generated ~~as of~~before the ~~end of 2017~~2018 tax year continue to be carried forward for 20 years and are ~~expected to be available~~able to fully offset taxable income ~~earned in the fiscal year ending December 31, 2022 ("fiscal year 2022"~~(“pre-2018 net operating losses”) ~~and future tax years.~~ .Federal net operating losses generated ~~after~~following the 2017 ~~totaling $46.5 million carried forward to fiscal~~tax year ~~2022, will be~~are carried forward indefinitely, but generally may only offset up to 80% of taxable income earned in a tax year (“post-2017 net operating losses”).

We carried $5.8 million of pre-2018 net operating losses and $46.5 million of post-2017 net operating losses into the 2023 tax year. We expect to utilize all of our NOLs in fiscal year 2023.

In addition, the TCJA added limitations on the deductibility of interest expense that became more restrictive beginning in tax year 2022 and potentially could limit the deductibility of some of our interest expense. Any interest expense limited may be carried forward indefinitely and utilized in later years subject to said interest limitation.

Liquidity and Capital Resources

We continually monitor our actual and forecasted cash flows, our liquidity, and our capital requirements in order to properly manage our liquidity needs as we move forward based on the capital intensive nature of our business and our growth acquisition strategy. We have ~~$252.8~~$272.3 million of undrawn capacity from our $300.0 million revolving credit facility ("Revolving Credit ~~Facility~~Facility") as of March 31, ~~2022~~2023 to help meet our short-term and long-term liquidity needs. We expect existing cash and cash equivalents combined with cash flows from operations and financing activities to continue to be sufficient to fund our operating activities and cash commitments for investing and financing activities for at least the next 12 months and thereafter for the foreseeable future.

Our known current- and long-term uses of cash include, among other possible demands: (1) acquisitions, (2) capital expenditures and leases, (3) repayments to service debt and other long-term obligations and (4) payments for final capping, closure and post-closure asset retirement obligations and environmental remediation liabilities. We have made in the past and plan to make in the future, acquisitions to expand service areas, densify existing operations, and grow services for our customers. Future acquisitions may include larger, more strategic acquisitions that may be inside or outside of our existing market, which could require additional financing either in the form of debt or equity.

Acquisitions, net of cash acquired. In the three months ended March 31, 2023, we paid $0.3 million in holdback payments on businesses previously acquired, as compared to the three months ended March 31, 2022 during which we acquired six businesses for total consideration of $53.5 million, including $49.8 million in ~~cash,~~cash.

Capital expenditures.

~~Capital expenditures. Capital expenditures were $13.9 million lower in the three months ended March 31,~~ 2022 ~~as compared to the three months ended March 31, 2021~~ primarily due to ~~the timing of~~higher capital spend ~~pertaining~~associated with (i) facility spend related to ~~our fleet, which has been delayed due to supply issues,~~the purchase of a transfer station that was formerly leased and ~~completion~~the retrofitting of ~~construction and~~a single-stream material recovery facility; (ii) development of ~~phase VI~~rail side infrastructure at our Subtitle D landfill located in ~~Coventry, Vermont in the fiscal year ended December 31, 2021.~~Mount Jewett, Pennsylvania and (iii) higher spend for vehicles, machinery, equipment and containers associated with business growth and inflationary pressures.

The increase in financing cash flows~~decreased $(25.6) million in the three months ended March 31, 2023 as compared to the three months ended March 31, 2022 is due to ~~increased~~ borrowings in the prior year period on our Revolving Credit Facility associated with acquisition activity.

Outstanding Long-Term Debt

Credit Facility

As of March 31, ~~2022,~~2023, we ~~had outstanding~~are party to an amended and restated credit agreement, dated as of December 22, 2021, as amended by the first amendment, dated as of February 9, 2023, and the second amendment, dated as of February 9, 2023 (the "Amended and Restated Credit Agreement"), which provides for a $350.0 million aggregate principal amount ~~of borrowings under our~~ term loan A facility ("Term Loan Facility") and ~~$19.0 million in borrowings under our~~a $300.0 million revolving credit facility ("Revolving Credit Facility" together with the Term Loan Facility, the "Credit Facility"), with a $75.0 million sublimit for letters of credit.(the Term Loan Facility and the Revolving Credit Facility together, the “Credit Facility”). The Credit Facility has a 5-year term that matures in December 2026 and bears interest at a rate of LIBOR plus 1.375% per annum, which will be reduced to a rate of LIBOR plus as low as 1.125% upon us reaching a consolidated net leverage ratio of less than 2.25x. The Credit Facility contains customary benchmark replacement provisions pursuant to which, upon certain triggering events, the LIBOR benchmark used to calculate the LIBOR rate will be replaced with a secured overnight financing rate, as adjusted, on the terms and conditions in the Credit Facility. The Credit Facility is guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries and secured by substantially all of our assets. As of March 31, 2022, further advances were available under the Credit Facility in the amount of $252.8 million. The available amount is net of outstanding irrevocable letters of credit totaling $28.2 million, and as of March 31, 2022 no amount had been drawn. We have the right to request, at our discretion, an increase in the amount of loans under the Credit Facility by an aggregate amount of $125.0 million, subject to the terms and conditions set forth in the Amended and Restated Credit Agreement.

The Credit Facility has a 5-year term that matures in December 2026. On February 9, 2023, we entered into first and second amendments to the Amended and Restated Credit Agreement. The first amendment provides, commencing in the fiscal year ending December 31, 2024, the interest rate margin applied for drawn and undrawn amounts under the Amended and Restated Credit Agreement shall be separately adjusted based on our achievement of certain thresholds and targets on two sustainability related key performance indicator metrics during fiscal year 2023: (i) metric tons of solid waste materials reduced, reused or recycled through our direct operations or with third-parties in collaboration with customers; and (ii) our total recordable incident rate. The second amendment provides that loans under the Amended and Restated Credit Agreement shall bear interest, at our election, at term secured overnight financing rate ("Term SOFR"), including a secured overnight financing rate adjustment of 10 basis points, or at a base rate, in each case, plus an applicable interest rate margin based on consolidated net leverage ratio, and plus or minus any sustainability rate adjustment. Unless loans are made as or converted to base rate loans, loans under the Amended and Restated Credit Agreement will bear interest at Term SOFR, including a secured overnight financing rate adjustment of 10 basis points, plus a margin based upon our consolidated net leverage ratio in the range of 1.125% to 2.125% per annum, plus a sustainability adjustment of up to positive or negative 4.0 basis point per annum. A commitment fee will be charged on undrawn amounts at a rate of Term SOFR, plus a margin based upon our consolidated net leverage ratio in the range of 0.20% to 0.40% per annum, plus a sustainability adjustment of up to positive or negative 1.0 basis points per annum. We are also required to pay a fronting fee for each letter of credit of 0.25% per annum. Interest under the Amended and Restated Credit Agreement is subject to increase by 2.00% per annum during the continuance of a payment default and may be subject to increase by 2.00% per annum during the continuance of any other event of default. The Credit Facility is guaranteed jointly and severally, fully and unconditionally by all of our significant wholly-owned subsidiaries and secured by substantially all of our assets. As of March 31, 2023, further advances were available under the Revolving Credit Facility in the amount of $272.3 million. The available amount is net of outstanding irrevocable letters of credit totaling $27.7 million, and as of March 31, 2023 no amount had been drawn.

The Amended and Restated Credit Agreement requires us to maintain a minimum interest coverage ratio and a maximum consolidated net leverage ratio, to be measured at the end of each fiscal quarter. As of March 31, 2023, we were in compliance with all financial covenants contained in the Amended and Restated Credit Agreement as follows (in millions):


Credit Facility Covenant	Twelve Months Ended March 31, 2023	Covenant Requirements at March 31, 2023
Maximum consolidated net leverage ratio (1)	2.06	4.00
Minimum interest coverage ratio	10.85	3.00

(1)The maximum consolidated net leverage ratio is calculated as consolidated funded debt, net of unencumbered cash and cash equivalents in excess of $2.0 million and up to $100.0 million (calculated at $537.9 million as of March 31, 2023, or $596.1 million of consolidated funded debt less $58.2 million of cash and cash equivalents in excess of $2.0 million and up to $100.0 million as of March 31, 2023), divided by consolidated EBITDA. Consolidated EBITDA is based on operating results for the twelve months preceding the measurement date of March 31, 2023. Consolidated funded debt, net of unencumbered cash and cash equivalents in excess of $2.0 million and up to $100.0 million, and consolidated EBITDA as defined by the Amended and Restated Credit Agreement ("Consolidated EBITDA") are non-GAAP financial measures that should not be considered an alternative to any measure of financial performance calculated and presented in accordance with generally accepted accounting principles in the United States. A reconciliation of net cash provided by operating activities to Consolidated EBITDA is as follows (in millions):


	Twelve Months Ended March 31, 2023
Net cash provided by operating activities	$	208.7
Changes in assets and liabilities, net of effects of acquisitions and divestitures	23.8



Stock based compensation	(7.9)
Operating lease right-of-use assets expense	(5.0)
Disposition of assets, other items and charges, net	(1.2)
Interest expense, less amortization of debt issuance costs	23.5
Provision for income taxes, net of deferred income taxes	5.6
Adjustments as allowed by the Amended and Restated Credit Agreement	13.1
Consolidated EBITDA	$	260.6

In addition to these financial covenants, the Amended and Restated Credit Agreement also contains a number of important customary affirmative and negative covenants which restrict, among other things, our ability to sell assets, incur additional debt, create liens, make investments, and pay dividends. As of March 31, ~~2022,~~2023, we were in compliance with the covenants contained in the Amended and Restated Credit Agreement. We do not believe that these restrictions impact our ability to meet future liquidity needs.

An event of default under any of our debt agreements could permit some of our lenders, including the lenders under the Credit Facility, to declare all amounts borrowed from them to be immediately due and payable, together with accrued and unpaid interest, or, in the case of the Credit Facility, terminate the commitment to make further credit extensions thereunder, which could, in turn, trigger cross-defaults under other debt obligations. If we were unable to repay debt to our lenders or were otherwise in default under any provision governing our outstanding debt obligations, our secured lenders could proceed against us and against the collateral securing that debt.

Based on the seasonality of our business, operating results in the late fall, winter and early spring months are generally lower than the remainder of our fiscal year. Given the cash flow impact that this seasonality, the capital intensive nature of our business and the timing of debt payments has on our business, we typically incur higher debt borrowings in order to meet our liquidity needs during these times. Consequently, our availability and performance against our financial covenants may tighten during these times as well.

Financing Activities

In April 2023, we entered into a commitment letter with lenders to obtain secured bridge financing in an amount of up to $375.0 million, less the amount of any term loan A ("Term Loan A"), and received the commitment of certain commitment parties to fund up to $261.5 million of a maximum of $400.0 million Term Loan A, which may be a delayed draw, under our Amended and Restated Credit Agreement to fund, in conjunction with cash and cash equivalents and borrowings from our Revolving Credit Facility the purchase of the equity interests of four wholly owned subsidiaries of GFL Environmental ("GFL Subsidiaries") . On April 21, 2023, we entered into an equity purchase agreement with GFL Environmental Inc. to purchase 100% of the equity interests of the GFL Subsidiaries that operate solid waste collection, transfer and recycling operations in Pennsylvania, Maryland, and Delaware for approximately $525.0 million in cash. The proposed acquisition includes nine hauling operations, one transfer station, and one material recovery facility. The acquisition is expected to close by the third quarter of fiscal year 2023, subject to customary closing conditions, including regulatory approvals.

Tax-Exempt Financings and Other Debt

As of March 31, ~~2022,~~2023, we had outstanding ~~$162.0~~$197.0 million aggregate principal amount of tax exempt bonds, ~~$44.8~~$48.8 million aggregate principal amount of finance leases and ~~$4.4~~$0.3 million aggregate principal amount of notes payable. See Note 7, Debt to our consolidated financial statements included in Part ~~I, Item~~I. Item. 1 of this Quarterly Report on Form 10-Q for further disclosure ~~over~~regarding debt.

Inflation

Inflationary increases in costs, including current inflationary pressures associated primarily with fuel, labor and certain other cost categories and capital items, have materially affected, and may continue to materially affect, our operating ~~margins.~~margins and cash flows. While ~~rapid~~ inflation negatively impacted operating results and margins during the three months ended March 31, 2023 and 2022, we believe that our flexible pricing structures and ~~mature~~ cost recovery fees are allowing us to recover and will continue to allow us to recover certain ~~of the cost of inflation~~inflationary costs from our customer base. Consistent with industry practice, most of our contracts and service agreements provide for a pass-through of certain costs to our customers, including increases in landfill tipping fees and in ~~some~~most cases fuel costs, intended to mitigate the impact of inflation on our operating results. We have also implemented a number of operating efficiency programs that seek to improve productivity and reduce our service costs, and aour fuel ~~surcharge,~~cost recovery program, which is the energy component of our E&E Fee, is designed to recover escalating fuel price fluctuations above ~~an annually~~a periodically reset floor. Despite these programs, competitive factors may require us to absorb at least a portion of these cost increases. See Item 3. "Quantitative and Qualitative Disclosures about Market Risk" included in this Quarterly Report on Form 10-Q for additional information regarding our fuel cost recovery program. Additionally, management’s estimates associated with inflation have had, and will continue to have, an impact on our accounting for landfill and environmental remediation liabilities.

Regional Economic Conditions

Our business is primarily located in the northeastern United States. Therefore, our business, financial condition and results of operations are susceptible to downturns in the general economy in this geographic region and other factors affecting the region, such as state regulations and severe weather conditions. We are unable to forecast or determine the timing and/or the future impact of a sustained economic slowdown.

Seasonality and Severe Weather

Our transfer and disposal revenues historically have been higher in the late spring, summer and early fall months. This seasonality reflects lower volumes of waste in the late fall, winter and early spring months because the volume of waste relating to C&D activities decreases substantially during the winter months in the northeastern United States.

Because certain of our operating and fixed costs remain constant throughout the fiscal year, operating income is therefore impacted by a similar seasonality. Our operations can be adversely affected by periods of inclement or severe weather, which may increase with the physical impacts of climate change and could increase our operating costs associated with the collection and disposal of waste, delay the collection and disposal of waste, reduce the volume of waste delivered to our disposal sites, increase the volume of waste collected under our existing contracts (without corresponding compensation), decrease the throughput and operating efficiency of our materials recycling facilities, or delay construction or expansion of our landfill sites and other facilities. Our operations can also be favorably affected by severe weather, which could increase the volume of waste in situations where we are able to charge for our additional services provided.

Our processing line-of-business in the Resource Solutions operating segment typically experiences increased volumes of fiber infrom November ~~and December~~through mid-January due to increased retail activity during the holiday season.

Critical Accounting Estimates and Assumptions

Our financial statements have been prepared in accordance with generally accepted accounting principles in the United States and necessarily include certain estimates and judgments made by management. On an on-going basis, management evaluates its estimates and judgments which are based on historical experience and on various other factors that are believed to be reasonable under the circumstances. The results of their evaluation form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions and circumstances. Our critical accounting estimates are more fully discussed in Item 7,7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" of our Annual Report on Form 10-K for the fiscal year ended December 31, ~~2021.~~2022.

New Accounting Pronouncements

For a description of the new accounting standards that may affect us, see Note 2, Accounting Changes to our consolidated financial statements included under Part I,I. Item 11. of this Quarterly Report on Form 10-Q.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the normal course of business we are exposed to market risks, including changes in diesel fuel prices, interest rates and certain commodity prices. We have a variety of strategies to mitigate these market risks, including those discussed below.

Fuel Price Risk

The price and supply of fuel are unpredictable and fluctuate based on events beyond our control, including among others, geopolitical developments, supply and demand for oil and gas, actions by the Organization of the Petroleum Exporting Countries and other oil and gas producers, war and unrest in oil producing countries and regional production patterns. Fuel is needed to run our fleet of trucks, equipment and other aspects of our operations, and price escalations for fuel increase our operating expenses. We have a fuel cost recovery program, which is the energy component of our energy and environmental fee ("E&E Fee(s)") that is designed to offset some or all of the impact of diesel fuel price increases above a periodically reset floor and contemplates a minimum customer participation level to cover changes in our fuel costs. The energy component of the E&E Fee floats on a monthly basis based upon changes in a published diesel fuel price index and is tied to a price escalation index with a look-back provision, which results in a timing lag in our ability to match the changes in the fuel cost component of the fee to diesel fuel price fluctuations during periods of rapid price changes. In certain circumstances, a substantial rise or drop in fuel costs could materially affect our revenue and costs of operations. However, a substantial rise or drop in fuel costs should not have a material impact on our results of operations. In addition, we are susceptible to increases in fuel surcharges from our vendors.

Based on our consumption levels in the last twelve months ended March 31, 2023, after considering physically settled fuel contracts we believe a $0.50 cent per gallon change in the price of diesel fuel would change our direct fuel costs by approximately $4.9 million per year. Offsetting these changes in direct fuel expense would be changes in the energy component of the E&E Fees charged to our customers. Based on participation rates as of March 31, 2023, we believe a $0.50 cent per gallon change in the price of diesel fuel would change the energy component of the E&E Fee by approximately $5.8 million per year. In addition to direct fuel costs related to our consumption levels, we are also subject to fuel surcharge expense from third party transportation providers. Other operational costs and capital expenditures may also be impacted by fuel prices.

Our fuel costs were $10.9 million in the three months ended March 31, 2023, or 4.2% of revenue, compared to $9.9 million in the three months ended March 31, 2022, or 4.2% of revenue.

Commodity Price Risk

We market a variety of materials, including fibers such as old corrugated cardboard and old newsprint, plastics, glass, ferrous and aluminum metals. We may use a number of strategies to mitigate impacts from these recycled material commodity price fluctuations including: (1) charging collection customers a floating sustainability recycling adjustment fee to reduce recycling commodity risks; (2) providing in-bound material recovery facilities (“MRF”) customers with a revenue share or indexed materials purchases in higher commodity price markets, or charging these same customers a processing cost or tipping fee per ton in lower commodity price markets; (3) selling recycled commodities to out-bound MRF customers through floor price or fixed price agreements; or (4) entering into fixed price contracts or hedges that mitigate the variability in cash flows generated from the sales of recycled paper at ~~times using derivative~~floating prices. Although we have introduced these risk mitigation programs to help offset volatility in commodity prices and to offset higher labor or capital costs to meet more stringent contamination standards, we cannot provide assurance that we can use these programs with our customers in all circumstances or that they will mitigate these risks in an evolving recycling environment. We do not use financial instruments for trading purposes and are not a party to ~~hedge some portion~~any leveraged derivatives. As of ~~these risks.~~March 31, 2023, we were not party to any commodity hedging agreements.

The impact of commodity price volatility market risk as of March 31, 2023 does not differ materially from that discussed in Item 7A, "Quantitative and Qualitative Disclosures About Market Risk" of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

Interest Rate ~~Volatility~~Risk

Our strategy to reduce exposure to interest rate risk involves entering into interest rate derivative agreements to hedge against adverse movements in interest rates related to the variable rate portion of our long-term debt. We have designated these derivative instruments as highly effective cash flow hedges, and therefore the change in fair value is recorded in our stockholders’ equity as a component of accumulated other comprehensive ~~loss~~income (loss) and included in interest expense at the same time as interest expense is affected by the hedged transactions. Differences paid or received over the life of the agreements are recorded as additions to or reductions of interest expense on the underlying debt and included in cash flows from operating activities.

As of March 31, ~~2022,~~2023, our active interest rate derivative agreements had total notional amounts of ~~$195.0~~$190.0 million. According to the terms of the agreements, we receive interest based on the 1-month ~~LIBOR~~London Inter-Bank Offered Rate ("LIBOR") index, in some instances restricted by a 0.0% floor, and pay interest at a weighted average rate of approximately ~~2.48%~~2.20% as of March 31, ~~2022.~~2023. The agreements mature between ~~June 2022~~May 2023 and ~~February~~June 2027. Additionally, as of March 31, ~~2022,~~2023, we ~~have~~had outstanding forward starting interest rate derivative agreements with a total notional ~~amounts~~amount of $60.0 million, ~~that mature between June 2027 and May 2028. We~~$20.0 million of which we will receive interest based on the 1-month LIBOR index, restricted by a 0.0% floor, and $40.0 million of which we will receive interest based on term secured overnight financing rate, restricted by a 0.0% floor. The agreements mature in May 2028 and will pay interest at a weighted average interest rate of ~~approximately 1.44%~~2.8%.

As of March 31, ~~2022,~~2023, we had ~~$211.2~~$246.1 million of fixed rate debt in addition to the ~~$195.0~~$190.0 million fixed through our interest rate derivative agreements. We had interest rate risk relating to approximately ~~$174.0~~$160.0 million of long-term debt as of March 31, ~~2022.~~2023. The weighted average interest rate on the variable rate portion of long-term debt was approximately ~~1.8%~~6.1% at March 31, ~~2022.~~2023. Should the average interest rate on the variable rate portion of long-term debt change by 100 basis points, we estimate that our annual interest expense would change by up to approximately ~~$1.7~~$1.6 million.

~~Commodity Price Volatility~~

~~Information about commodity price volatility market risk as of March 31, 2022 does not differ materially from that discussed in Item 7A, "Quantitative and Qualitative Disclosures About Market Risk" of our Annual Report on Form 10-K for the fiscal year ended December 31, 2021.~~

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures. Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, ~~2022.~~2023. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (“Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the ~~SEC’s~~Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, ~~2022,~~2023, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in internal controls over financial reporting. No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the three months ended March 31, ~~2022~~2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

General Legal Proceedings

The information required by this Item is provided in Note 8, Commitments and Contingencies to our consolidated financial statements included in Part I,I. Item 11. of this Quarterly Report on Form 10-Q.

Legal Proceedings over Certain Environmental Matters Involving Governmental Authorities with Possible Sanctions of $1,000,000 or More

Item 103 of the ~~SEC's~~Securities and Exchange Commission's Regulation S-K requires disclosure of certain environmental matters when a governmental authority is a party to the proceedings and the proceedings involve potential monetary sanctions unless we reasonably believe the monetary sanctions, exclusive of interest and costs, will not equal or exceed a specified threshold which we determine is reasonably designed to result in disclosure of any such proceeding that is material to our business or financial condition. Pursuant to Item 103, we have determined such disclosure threshold to be $1,000,000. We have no matters to disclose in accordance with that requirement.

ITEM 1A. RISK FACTORS

Our business is subject to a number of risks, including those identified in Item 1A, “Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, ~~2021,~~2022, that could have a material effect on our business, results of operations, financial condition and/or liquidity and that could cause our operating results to vary significantly from period to period. We may disclose additional changes to our risk factors or disclose additional factors from time to time in our future filings with the Securities and Exchange Commission.
