NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(in thousands, except for per share data)

Casella Waste Systems, Inc. (“Parent”), and its consolidated subsidiaries (collectively, “we”, “us” or “our”), is a regional, vertically integrated solid waste services company that provides collection, transfer, disposal, landfill, landfill gas-to-energy, recycling and organics services in the northeastern United States. We market recyclable metals, aluminum, plastics, paper and corrugated cardboard, which have been processed at our recycling facilities, as well as recyclables purchased from third-parties. 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, and our larger-scale recycling and commodity brokerage operations through our Recycling segment. Organics services, ancillary operations, major account and industrial services, discontinued operations and earnings from equity method investees, as applicable, are included in our Other segment.

The accompanying unaudited consolidated financial statements, which include the accounts of the Parent, our wholly-owned subsidiaries and any partially owned entities over which we have a controlling financial interest, 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 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, which was filed with the SEC on March 2, 2016.

For comparative purposes, certain prior period amounts in the consolidated financial statements, including the presentation of debt issuance costs, have been reclassified to conform to the current period presentation. See Note 2, Accounting Changes for discussion regarding changes to the presentation of debt issuance costs and Note 5, Long-Term Debt for the updated disclosure.

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, 2016 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 Form 10-K for the fiscal year ended December 31, 2015.

Subsequent Events

We have evaluated subsequent events or transactions that have occurred after the consolidated balance sheet date of March 31, 2016, but prior to the filing of the consolidated financial statements with the SEC on this Quarterly Report on Form 10-Q. We have determined that, except as disclosed, there are no subsequent events that require disclosure in this Quarterly Report on Form 10-Q.

Intangible amortization expense for the three months ended March 31, 2016 and 2015 was $524 and $749, respectively.

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 timeframe 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. The changes to accrued final capping, closure and post-closure liabilities are as follows:

(Gain) Loss on Debt Extinguishment

Senior Subordinated Notes. In the three months ended March 31, 2016, we repurchased and permanently retired $4,230 aggregate principal amount of 7.75% senior subordinated notes due February 2019 (“2019 Notes”) at a repurchase price of $96.75 in order to maximize interest savings by paying down our most expensive debt. As a result of the repurchase, we recorded a gain on debt extinguishment of $48 in the three months ended March 31, 2016 related to the non-cash gain associated with the below par repurchase price, net of the write off of debt issuance costs and unamortized original issue discount in proportion with the settlement amount.

Senior Credit Facility. In the three months ended March 31, 2015, we recorded a charge of $521 as a loss on debt extinguishment related to the write-off of debt issuance costs in connection with changes to the borrowing capacity from the

10

senior revolving credit and letter of credit facility that was due March 2016 (“Senior Credit Facility”) to the new senior secured asset-based revolving credit and letter of credit facility due February 2020 (“ABL Facility”). The remaining unamortized deferred financing costs of the Senior Credit Facility, along with fees paid to the creditor and third-party costs incurred for the ABL Facility, are to be amortized over the term of the ABL Facility.

Legal Proceedings

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 have been 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.

In accordance with FASB ASC 450-20, we accrue for legal proceedings, inclusive of legal costs, when losses become probable and reasonably estimable. 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.

Expera Old Town, LLC v. Casella Waste Systems, Inc.

On or about November 6, 2015, Expera Old Town, LLC (“Expera”) filed a lawsuit against us in Maine Superior Court, seeking damages for breach of contract and unjust enrichment and an action for declaratory judgment (“Lawsuit”). Expera was a successor-in-interest to a contract between us and Old Town Fuel and Fiber (“OTFF”), the former owner of a pulp manufacturing facility (“Facility”) located in Old Town, Maine (“Contract”). Expera purchased the Facility during the pendency of the bankruptcy of OTFF. Since the filing of the Lawsuit, Expera has sold the Facility and related assets to MFGR LLC (“MFGR”). MFGR alleged that we had the obligation to provide a specialized type of wood fuel to the Facility or, alternatively, that we owed a “Fuel Replacement Fee” of up to $2,000 a year (subject to the possibility of certain credits against such payments). The Contract was to expire in 2036.

On or about February 10, 2016, we reached an agreement in principle with MFGR to dismiss the Lawsuit with prejudice, and to resolve all outstanding claims of any nature including future claims which could arise under the Contract, and a Joint Stipulation of Dismissal with Prejudice was filed with the Superior Court on April 15, 2016. On or about April 12, 2016, the Parties entered into a Settlement Agreement (“SA”) along with other ancillary agreements. Pursuant to the SA, we will pay MFGR $1,250 upon execution of the SA, and $350 a year for five years following execution of the SA. Accordingly, taking into account the net present value of the settlement payments, we have recorded a reserve of $2,616 as of March 31, 2016. This includes a contract settlement charge of $1,940 and $676 of operating expenses recorded in the fiscal year ended December 31, 2015. We also have reserved $46 as of March 31, 2016 for legal costs associated with the Lawsuit and SA.

We have also entered into a new leachate disposal agreement at market prices with MFGR for the treatment of leachate from the landfill managed by us for the state of Maine located in Old Town, Maine (“Juniper Ridge”), and MFGR has entered into a waste disposal agreement at market prices with us for the disposal at Juniper Ridge of waste materials produced in the demolition or re-purposing of the Facility.

Environmental Remediation Liability

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. The following matters represents our potential or outstanding material claims.

Southbridge Recycling & Disposal Park, Inc.

In October 2015, our Southbridge Recycling and Disposal Park, Inc. (“SRD”) subsidiary reported to the Massachusetts Department of Environmental Protection (“MADEP”) results of analysis of samples collected pursuant to our existing permit from private drinking water wells located near the landfill operated by SRD. Those results indicated the presence of contaminants above the levels triggering notice and response obligations under MADEP regulations. In response to those results, we are carrying out an Immediate Response Action pursuant to state law. Further, we have implemented a plan to analyze and better understand the groundwater near the landfill and we are investigating with the objective of identifying the source or sources of the elevated levels of contamination measured in the well samples. If it is determined that some or all of the contamination originated at the landfill, we will work with the Town of Southbridge, the landfill owner, to evaluate and possibly allocate the liabilities related to that contamination. In February 2016, we received a Notice of Intent to Sue under the Resource Conservation and Recovery Act from a law firm representing residents from approximately 40 homes located in the vicinity of the landfill, indicating its intent to file suit against us. We believe it is reasonably possible that a loss may occur as a result of this potential matter although an estimate of loss cannot be reasonably estimated at this time.

Potsdam Environmental Remediation Liability

On December 20, 2000, the State of New York Department of Environmental Conservation (“DEC”) issued an Order on Consent (“Order”) which named Waste-Stream, Inc. (“WSI”), our subsidiary, General Motors Corporation (“GM”) and Niagara Mohawk Power Corporation (“NiMo”) as Respondents. The Order required that the Respondents undertake certain work on a 25-acre scrap yard and solid waste transfer station owned by WSI in Potsdam, New York, including the preparation of a Remedial Investigation and Feasibility Study (“Study”). A draft of the Study was submitted to the DEC in January 2009 (followed by a final report in May 2009). The Study estimated that the undiscounted costs associated with implementing the preferred remedies would be approximately $10,219. On February 28, 2011, the DEC issued a Proposed Remedial Action Plan for the site and accepted public comments on the proposed remedy through March 29, 2011. We submitted comments to the DEC on this matter. In April 2011, the DEC issued the final Record of Decision (“ROD”) for the site. The ROD was subsequently rescinded by the DEC for failure to respond to all submitted comments. The preliminary ROD, however, estimated that the present cost associated with implementing the preferred remedies would be approximately $12,130. The DEC issued the final ROD in June 2011 with proposed remedies consistent with its earlier ROD. An Order on Consent and Administrative Settlement naming WSI and NiMo as Respondents was executed by the Respondents and DEC with an effective date of October 25, 2013. On January 29, 2016, a Cost-Sharing Agreement was executed between WSI, NiMo, Alcoa Inc. (“Alcoa”) and Reynolds Metal Company (“Reynolds”) whereby Alcoa and Reynolds elected to voluntarily participate in the onsite remediation activities at a 15% participant share. It is unlikely that any significant expenditures relating to onsite remediation will be incurred until the fiscal year ending December 31, 2017. WSI is jointly and severally liable with NiMo, Alcoa and Reynolds for the total cost to remediate.

We have recorded an environmental remediation liability associated with the Potsdam site based on incurred costs to date and estimated costs to complete the remediation in other accrued liabilities and other long-term liabilities. Our expenditures could be significantly higher if costs exceed estimates. 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 of 1.8%. The changes to the environmental remediation liability associated with the Potsdam environmental remediation liability are as follows:

Stock Based Compensation

Shares Available For Issuance

In the fiscal year ended April 30, 2007, we adopted the 2006 Stock Incentive Plan (“2006 Plan”). The 2006 Plan was amended in the fiscal year ended April 30, 2010. Under the 2006 Plan, we may grant awards up to an aggregate amount of shares equal to the sum of: (i) 2,475 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 as were subject to stock options granted under our 1993 Incentive Stock Option Plan, 1994 Non-statutory Stock Option Plan, 1996 Stock Option Plan, and 1997 Stock Incentive Plan (“Prior Plans”), which were not actually issued under the Prior Plans because such stock options expire or otherwise result in shares not being issued. As of March 31, 2016, there were 546 Class A common stock equivalents available for future grant under the 2006 Plan, inclusive of additional Class A common stock equivalents that were previously issued under our terminated plans and have become available for grant because such awards expired or otherwise resulted in shares not being issued. No awards may be granted under the 2006 Plan after October 10, 2016 and accordingly we expect to implement a new stock incentive plan which would be recommended to stockholders for approval at the 2016 Annual Meeting of Stockholders.

Stock Options

Stock options granted under the 2006 Plan are granted at a price equal to the prevailing fair market 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 to four year period from the date of grant.

The following table summarizes stock option activity:

Stock-based compensation expense for stock options was $146 during the three months ended March 31, 2016, as compared to $157 during the three months ended March 31, 2015.

As of March 31, 2016, total unrecognized stock-based compensation expense related to outstanding stock options was $1,078, which will be recognized over a weighted average period of 2.1 years.

Other Stock Awards

We grant restricted stock awards, restricted stock units and performance-based stock units under the 2006 Plan at a price equal to the fair market value of our Class A common stock at the date of grant. 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 vest incrementally over an identified service period beginning on the grant date based on continued employment. Performance-based stock units vest at a future date following the grant date and are based on the attainment of certain performance targets.

13

The following table summarizes restricted stock, restricted stock unit and performance-based stock unit activity:

Stock-based compensation expense related to restricted stock, restricted stock units and performance-based stock units was $550 during the three months ended March 31, 2016, as compared to $486 during the three months ended March 31, 2015.

During the three months ended March 31, 2016, the total fair value of other stock awards vested was $1,006.

As of March 31, 2016, total unrecognized compensation expense related to outstanding restricted stock and restricted stock units was $3,839, which will be recognized over a weighted average period of 1.9 years. Maximum unrecognized stock-based compensation expense as of March 31, 2016 related to outstanding performance-based stock units was $451 to be recognized over a weighted average period of 2.8 years.

We also recorded $26 of stock-based compensation expense related to our Amended and Restated 1997 Employee Stock Purchase Plan during the three months ended March 31, 2016, as compared to $17 during the three months ended March 31, 2015.

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 which we believe market participants would use in pricing an asset or a liability.

Assets and Liabilities Accounted for at Fair Value

Our financial instruments for the periods reported below include cash and cash equivalents, restricted investments held in trust on deposit with various banks as collateral for our obligations relative to our landfill final capping, closure and post-closure costs, restricted cash reserved to finance certain capital projects, trade receivables, interest rate derivatives, trade payables and long-term debt. The carrying values of cash and cash equivalents, trade receivables and trade payables approximate their respective fair values due to their short-term nature. The fair value of restricted investments held in trust and restricted cash, 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 derivative, included in the Level 2 tier below, was calculated based on a valuation obtained from our counter-party based primarily on the three month LIBOR yield curve that is observable at commonly quoted intervals for the full term of the swap. The interest rate derivative matured on March 15, 2016. We recognize all derivatives on the balance sheet at fair value.

15

Our financial assets and liabilities that are measured at fair value on a recurring basis include the following:

Fair Value of Debt

As of March 31, 2016, the fair value of our fixed rate debt, including our 2019 Notes, Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-2 (“FAME Bonds 2005R-2”), Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2015 (“FAME Bonds 2015”), Vermont Economic Development Authority Solid Waste Disposal Long-Term Revenue Bonds Series 2013 (“Vermont Bonds”), New York State Environmental Facilities Corporation Solid Waste Disposal Revenue Bonds Series 2014 (“New York Bonds”) and Solid Waste Disposal Revenue Bonds Series 2013 issued by the Business Finance Authority of the State of New Hampshire (“New Hampshire Bonds”) was approximately $463,484 and the carrying value was $454,470. The fair value of the 2019 Notes are considered to be Level 1 within the fair value hierarchy as the fair value is based off of a quoted market price in an active market. The fair value of the FAME Bonds 2005R-2, the FAME Bonds 2015, the Vermont Bonds, the New York Bonds and the New Hampshire 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.

Although we have determined the estimated fair value amounts of the FAME Bonds 2005R-2, the FAME Bonds 2015, the Vermont Bonds, the New York Bonds and the New Hampshire 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. As of March 31, 2016, the fair value of our ABL Facility is considered to be Level 2 within the fair value hierarchy as the fair value approximates its carrying value of $68,000 based on current borrowing rates for similar types of borrowing arrangements. The carrying value of our remaining material variable rate debt, the Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-1, approximates fair value because the interest rate for the debt instrument is based on a market index that approximates current market rates for instruments with similar risk and maturities.

Maine Energy

In the fiscal year ended April 30, 2013, we executed a purchase and sale agreement with the City of Biddeford, Maine, pursuant to which we agreed to sell the real property of Maine Energy Recovery Company, LP (“Maine Energy”) to the City of Biddeford. We agreed to sell Maine Energy for an undiscounted purchase consideration of $6,650, which was to be paid to us in installments over twenty-one years. The transaction closed in November 2012. In December 2012, we ceased operations of the Maine Energy facility and initiated the decommissioning, demolition and site remediation process in accordance with the provisions of the agreement. We have completed the demolition process and site remediation under the auspices and in accordance with work plans approved by the Maine Department of Environmental Protection and the U.S. Environmental Protection Agency. In consideration of the fact that the project was substantially completed and based on incurred costs to date and estimates at that time regarding the remaining costs to fulfill our obligation under the purchase and sale agreement, we reversed a reserve of $1,157 of excess costs to complete the divestiture in the three months ended March 31, 2015. As of March 31, 2016, we had no remaining costs to complete the divestiture accrued as we had fulfilled our obligation under the agreement.

CARES and Related Transaction

Casella-Altela Regional Environmental Services, LLC (“CARES”) is a joint venture that owned and operated a water and leachate treatment facility for the natural gas drilling industry in Pennsylvania. Our joint venture partner in CARES is Altela, Inc. (“Altela”). As of March 31, 2016, our ownership interest in CARES was 51%. In accordance with FASB ASC 810-10-15, we consolidate the assets, liabilities and results of operations of CARES into our consolidated financial statements due to our controlling financial interest in the joint venture.

On February 9, 2015, we executed a purchase and sale agreement pursuant to which we and Altela agreed to sell certain assets of the CARES water treatment facility to an unrelated third-party. We sold these assets of CARES for purchase consideration of $3,500, resulting in a gain of $2,850 in the three months ended March 31, 2015, 49% of which was attributable to Altela, the noncontrolling interest holder. In connection with this transaction, we also sold certain of our equipment and real estate to the same buyer for total consideration of $1,050, resulting in a gain of $928 in the three months ended March 31, 2015.

As of March 31, 2016, we were proceeding with dissolution of CARES in accordance with the CARES Limited Liability Company Agreement.

We report selected information about 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, the Western and Eastern regions. Revenues associated with our solid waste operations are derived mainly from solid waste collection and disposal, landfill, landfill gas-to-energy, transfer and recycling services in the northeastern United States. Our revenues in the Recycling segment are derived from municipalities and customers in the form of processing fees, tipping fees and commodity sales. Organics services, ancillary operations, major account and industrial services, discontinued operations, and earnings from equity method investees, as applicable, are included in our Other segment.

17

Amounts of our total revenue attributable to services provided are as follows:

Our 2019 Notes are guaranteed jointly and severally, fully and unconditionally, by our significant wholly-owned subsidiaries. The Parent is the issuer and a non-guarantor of the 2019 Notes and the Parent has no independent assets or operations. The information which follows presents the condensed consolidating financial position as of March 31, 2016 and December 31, 2015, the consolidating results of operations and comprehensive loss for the three months ended March 31, 2016 and 2015, and the condensed consolidating statements of cash flows for the three months ended March 31, 2016 and 2015 of (a) the Parent company only, (b) the combined guarantors (“Guarantors”), each of which is 100% wholly-owned by the Parent, (c) the combined non-guarantors (“Non-Guarantors”), (d) eliminating entries and (e) the consolidated total.
