ISS Recognizes Recent Substantial Improvements by Casella Board

Casella Urges Stockholders to Follow ISS' Recommendation and Vote on the WHITE Proxy Card

RUTLAND, Vt.--(BUSINESS WIRE)-- Casella Waste Systems, Inc. (Nasdaq: CWST) ("Casella" or the "Company"), a regional solid waste, recycling, and resource management services company, today announced that Institutional Shareholder Services Inc. ("ISS"), a leading independent proxy advisory firm, has issued a report recommending that Casella stockholders vote the WHITE proxy card FOR ALL three of Casella's director-nominees - John W. Casella, William P. Hulligan and James E. O'Connor - standing for election at the 2015 Annual Meeting of Stockholders to be held on November 6, 2015. ISS' clients include institutional investors, mutual funds, pension funds and other fiduciaries. As previously disclosed, JCP Investment Management, LLC ("JCP") is conducting a proxy contest and is seeking the election at the 2015 Annual Meeting of two director candidates in opposition to the highly qualified and very experienced nominees unanimously recommended by the Casella Board.

Commenting on the ISS report, Casella issued the following statement:

"We are very pleased that ISS, one of the leading independent, third-party proxy advisory firms, has carefully reviewed the voting alternatives and has recommended that stockholders vote for all three of Casella's director nominees on the WHITE proxy card. As we have stated consistently, we do not believe that any of JCP's nominees have experience comparable to that of any of the highly qualified and very experienced members of the Casella Board that JCP is seeking to replace and we believe that JCP's proposed board candidates lack the relevant experience necessary to drive long-term stockholder value. We also do not believe that any of JCP's nominees would bring to Casella's Board any relevant insights, perspectives, skills or competencies not already present among the current members of the Casella Board."

In its October 24, 2015 report recommending that Casella stockholders vote the WHITE proxy card FOR ALL three of the highly qualified and experienced director-nominees recommended by the Casella Board, ISS noted in its conclusion that JCP had not made a compelling case that additional change to Casella's Board is needed and that votes for the Casella Board's nominees on the WHITE proxy card are warranted.

Additionally, ISS highlighted the significant and numerous positive changes that have already occurred at Casella. In particular, ISS took note of the refreshment of the Casella Board of Directors that has taken place, recognizing that four new directors have been added to the Casella Board since 2008. ISS noted:

"The two most recent additions [William P. Hulligan and James E. O'Connor], both within the past year, appear to reflect the board's commitment to chart a new course, in part, by adding credible industry expertise to the independent directors."

ISS also took note of the significant progress and momentum Casella has achieved in executing on its strategy, strengthening its management team, simplifying and streamlining its business, reducing its exposure to risk, improving its financial performance and positioning Casella for long-term growth and profitability. ISS noted that:

"the current board appears to have made meaningful effort to put the company back onto a more promising path, including through reshuffling management, reassessing pricing structures, divesting underperforming assets, cost controls and focus on operational efficiency. Casella's most recent financial results also appear to support the board's assertions that its strategy is yielding improvements."

With respect to JCP's proposed board candidates, ISS noted its concern that the JCP nominees may not bring to the Casella Board any perspectives not already present among the current members of the Casella Board and the risk that JCP's proposed board candidates could have an adverse effect on the progress and momentum that Casella has achieved in executing on its strategy. As ISS recognized:

"the risk of derailing the recent improvements overseen by the current board appears to outweigh the potential benefits of injecting additional, but potentially duplicative new perspective to the board."

Casella stockholders are reminded that their vote is extremely important, no matter how many or how few shares they own. All stockholders of record as of September 18, 2015 are entitled to vote at the 2015 Annual Meeting of Stockholders. Casella urges stockholders to vote FOR ALL three of Casella's director nominees - John W. Casella, William P. Hulligan and James E. O'Connor - on the WHITE proxy card today.

Stockholders may vote by returning the WHITE proxy card or by phone or Internet by following the instructions on the WHITE proxy card they have received. Stockholders are urged to discard any gold proxy card or voting instruction form they may have received from JCP. Even a WITHHOLD vote with respect to JCP's nominees on its gold proxy card will cancel any proxy previously given to Casella. If a stockholder previously signed a gold proxy card sent by JCP, that proxy card can be revoked by voting a new WHITE proxy card for the Board's recommended nominees. Only the latest-dated proxy will count.

In order for stockholders to have access to all relevant information concerning the 2015 Annual Meeting that Casella has made available, Casella has developed a website focused on the 2015 Annual Meeting, which is accessible at www.casellastockholders.com.

Casella is being advised in connection with the proxy contest by Wilmer Cutler Pickering Hale and Dorr LLP and Morgan, Lewis & Bockius LLP. Mackenzie Partners, Inc. is serving as Casella's proxy solicitor.
