Item 8.01 Other Events

On March 8, 2017, Patrick Industries, Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Merrill Lynch, Pierce, Fenner & Smith Incorporated, Wells Fargo Securities, LLC, and Robert W. Baird & Co. Incorporated, and each of the other Underwriters named in Schedule A thereto (the “Underwriters”), pursuant to which the Company agreed to sell 1,350,000 shares of common stock (the “Shares”), no par value, to the Underwriters (the “Offering”) and granted the Underwriters a 30-day option to purchase from the Company up to an additional 202,500 shares of its common stock. The Company will receive total gross proceeds (before underwriter’s discounts and commissions) of approximately $98.6 million from the Offering, assuming that the option to purchase additional shares is not exercised.

The Shares will be issued under the Company’s shelf registration statement on Form S-3 (No. 333-204777) filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”). The material terms of the Offering are described in the prospectus supplement dated March 8, 2017.

The Offering is expected to close on March 14, 2017, subject to the satisfaction of the closing conditions set forth in the Underwriting Agreement. Under the Underwriting Agreement, the Company has also agreed to indemnify the Underwriter against certain liabilities, or to contribute to payments that the Underwriter may be required to make in respect of those liabilities.

Some of the Underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with the Company or its affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

The foregoing description of the Underwriting Agreement does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the Underwriting Agreement, which is filed as Exhibit 1.1 to this Current Report on Form 8-K and incorporated by reference herein.

In connection with the Offering, McDermott Will & Emery LLP rendered their opinion as to the validity of the shares of common stock to be sold in the Offering, which opinion is filed as Exhibit 5.1 hereto and is incorporated by reference herein.
