Item 1.01                                           Entry into a material Definitive Agreement.

On February 21, 2017, Comfort Systems USA, Inc. (the “Company”) entered into a Stock Purchase Agreement (the “Purchase Agreement”) with BCH Holdings, Inc., a Florida corporation (“BCH”), the holders of all the outstanding securities of BCH (collectively, the “Selling Shareholders”) and Daryl W. Blume, as representative of the Selling Shareholders, pursuant to which the Company will acquire all of the outstanding securities of BCH.

Pursuant to the Purchase Agreement, at the closing of the transaction, the Company has agreed to pay to the Selling Shareholders an initial aggregate purchase price comprised of approximately $85.7 million payable in cash subject to working capital and certain other adjustments set forth in the Purchase Agreement, and $14.3 million aggregate principal amount of unsecured promissory notes (the “Notes”) in favor of the Selling Shareholders bearing interest at a rate of 3% per annum and maturing on the fourth anniversary of the closing of the transaction. In addition, the Purchase Agreement provides for an additional earn-out amount to become payable by the Company to the extent that BCH’s EBITDA (as defined in the accompanying earn-out agreement) during each of the years following the closing of the transaction through December 31, 2021 exceeds certain thresholds (the “Earn-Out Payments”). The Notes and the Earn-Out Payments will be subject to offset by the Company in respect of any indemnity claims made pursuant to the Purchase Agreement. The Purchase Agreement contains customary representations, warranties, covenants and indemnities. The closing of the transaction is subject to customary closing conditions.

The foregoing description of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the Purchase Agreement, a copy of which is filed as Exhibit 2.1 hereto and is incorporated herein by reference.

The Purchase Agreement and the above description have been included to provide investors with information regarding the terms of the Purchase Agreement. They are not intended to provide any other factual information about the Company, BCH or their respective subsidiaries or affiliates. The representations, warranties and covenants contained in the Purchase Agreement were made only for purposes of those agreements and as of specific dates, were solely for the benefit of the parties to the Purchase Agreement, and may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made by each contracting party to the other for the purposes of allocating contractual risk between them that differ from those applicable to investors. Investors should be aware that the representations, warranties and covenants or any description thereof may not reflect the actual state of facts or condition of the Company, BCH or any of their respective subsidiaries, affiliates or businesses. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Purchase Agreement, which subsequent information may or may not be fully reflected in public disclosures by the Company or BCH. Accordingly, investors should read the representations and warranties in the Purchase Agreement not in isolation but only in conjunction with the other information about the Company and BCH and their respective subsidiaries that the Company includes in reports, statements and other filings that it makes with the U.S. Securities and Exchange Commission.
