RUTLAND, VT -- (Marketwire) -- 09/28/12 -- Casella Waste Systems, Inc. (NASDAQ: CWST) (the "Company"), a vertically-integrated solid waste, recycling and resource management services company, announced today that it priced the previously announced offering of 7 3/4% senior subordinated notes due 2019 (the "Notes").

The aggregate principal amount of the Notes is $125.0 million. The Notes are being offered as additional debt securities under an indenture pursuant to which the Company previously issued senior subordinated notes (the "Existing Notes"). The Notes and the Existing Notes initially will have different CUSIP numbers. However, the Company expects to register the Notes under the Securities Act of 1933, as amended (the "Securities Act") and following such registration, the Company intends to exchange the Notes for unrestricted notes with the same CUSIP as the Existing Notes, and the Notes and the Existing Notes will be fungible thereafter.

The issuance of the Notes is anticipated to close on October 9, 2012. The Notes will pay interest on a semi-annual basis.

The Company intends to use the net proceeds of the offering to refinance its 11% Senior Second Lien Notes due 2014, of which $180,000,000 aggregate principal amount is outstanding.

The Notes are being offered in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to non-U.S. persons outside the United States under Regulation S under the Securities Act.

The Notes have not been registered under the Securities Act, and unless so registered, may not be offered or sold in the United States absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable securities laws.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy the Notes, nor shall there be any sale of the Notes in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction. This notice is being issued pursuant to and in accordance with Rule 135c under the Securities Act.
