Introduction

On September 22, 2014, PGT, Inc. (the “PGTI”), through its wholly-owned subsidiary PGT Industries, Inc. (“PGT”), completed the merger (the “Merger”) of PGT’s wholly-owned subsidiary, Hot Ledge Company, a Delaware corporation (“Acquisition Sub”), with and into CGI Windows and Doors Holdings, Inc., a Delaware corporation (“CGI”), in accordance with the terms and conditions of the Agreement and Plan of Merger dated July 25, 2014 (the “Merger Agreement”) among PGT, CGI, Acquisition Sub and Cortec Group Fund IV, L.P., solely in its capacity as the representative of the equity holders of CGI (the “Representative”). As a result of the Merger, CGI, the surviving entity in the Merger, became a wholly-owned subsidiary of PGT.

Item 1.01 Entry Into A Material Definitive Agreement.

On September 22, 2014, the PGTI entered into a Credit Agreement (the “Credit Agreement”), among PGTI, the lending institutions identified in the Credit Agreement, and Deutsche Bank AG New York Branch, as Administrative Agent and Collateral Agent. The Credit Agreement establishes new senior secured credit facilities in an aggregate amount of $235.0 million, consisting of a $200.0 million Tranche B term loan facility maturing in seven years that will amortize on a basis of 1% annually during the seven-year term, and a $35.0 million revolving credit facility maturing in five years that includes a swing line facility and a letter of credit facility. PGTI’s obligations under the Credit Agreement are secured by substantially all of its and its direct and indirect subsidiaries’ assets.

Interest on all loans under the Credit Agreement is payable either quarterly or at the expiration of any LIBOR interest period applicable thereto. Borrowings under the term loans and the revolving credit facility accrue interest at a rate equal to, at our option, a base rate (with a floor of 200 basis points in respect of the term loan) or LIBOR (with a floor of 100 basis points in respect of the term loan) plus an applicable margin. The applicable margin is 425 basis points in the case of LIBOR and 325 basis points in the case of the base rate. We will pay quarterly fees on the unused portion of the revolving credit facility equal to 50 basis points per annum as well as a quarterly letter of credit fee at 425 basis points per annum on the face amount of any outstanding letters of credit.

The Credit Agreement contains a springing financial covenant, if PGTI draws in excess of twenty percent (20%) of the revolving facility, which requires us to maintain a maximum total net leverage ratio (based on the ratio of total debt for borrowed money to trailing EBITDA, each as defined in the Credit Agreement), and will be tested quarterly based on the last four fiscal quarters and is set at levels as described in the Credit Agreement.

The Credit Agreement also contains a number of affirmative and restrictive covenants, including limitations on the incurrence of additional debt, liens on property, acquisitions and investments, loans and guarantees, mergers, consolidations, liquidations and dissolutions, asset sales, dividends and other payments in respect of our capital stock, prepayments of certain debt and transactions with affiliates. The Credit Agreement also contains customary events of default. Upon the occurrence of an event of default, the amounts outstanding under the Credit Agreement may be accelerated and may become immediately due and payable.

The foregoing description of the Credit Agreement is not complete and is subject to, and qualified in its entirety by, the full text of the Credit Agreement, a copy of which is attached to this Current Report on Form 8-K (this “Current Report”) as Exhibit 10.1 and is incorporated herein by reference.

Item 1.02 Termination of a Material Definitive Agreement.

On September 22, 2014, in connection with the Merger, PGTI terminated its Credit Agreement (“Old Credit Agreement”) dated as of May 28, 2013, among PGTI, PGT, the lenders party thereto, certain other financial institutions and SunTrust Bank as Administrative Agent and Collateral Agent. A portion of the proceeds from the Credit Agreement were used to repay all amounts outstanding under the Old Credit Agreement and pay related fees and expenses. There were no penalties associated with the termination of the Old Credit Agreement.

Item 2.01 Completion of Acquisition or Disposition of Assets.

On September 22, 2014, PGT completed the Merger in accordance with the terms of the Merger Agreement. As a result of the Merger, CGI, the surviving entity in the Merger, became a wholly-owned subsidiary of PGT. Under the terms of the Merger Agreement, at the effective time of the Merger, all outstanding shares of capital stock of CGI were cancelled and converted into the right to receive aggregate merger consideration of $111 million in cash, adjusted with respect working capital, cash, indebtedness and unpaid transaction expenses of CGI as of the closing date of the Merger.

The foregoing description of the Merger Agreement is not complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, which was attached as Exhibit 2.1 to PGTI’s Current Report on Form 8-K filed with the SEC on July 29, 2014, the terms of which are incorporated herein by reference.
