On December 13, 2016, PBF Energy Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Wells Fargo Securities, LLC (the “Underwriter”), pursuant to which the Company agreed to sell 10,000,000 shares of its Class A common stock (the “Shares”), par value $0.001 per share, to the Underwriter (the “Offering”) and granted the Underwriter a 30-day option to purchase from the Company up to an additional 1,500,000 shares of its Class A common stock. The Company will receive total gross proceeds (before underwriter’s discounts and commissions) of approximately $277.5 million from the Offering.

The Shares will be offered under the Company’s shelf registration statement on Form S-3 (No. 333-193210) 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 December 13, 2016.

The Offering is expected to close on December 19, 2016, 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.

The Underwriter and/or certain of its affiliates perform and/or have performed commercial and investment banking and advisory services for the Company and/or its affiliates from time to time for which they receive and/or have received customary fees and expenses. The Underwriter and/or certain of its affiliates may, from time to time, engage in transactions with and perform services for the Company and/or its affiliates in the ordinary course of their business for which they will receive fees and expenses, including serving as administrative agent under PBF Logistics LP’s credit facility and term loans. 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, Stroock & Stroock & Lavan LLP rendered their opinion as to the validity of the shares of Class A common stock to be sold in the Offering, which opinion is filed as Exhibit 5.1 hereto and is incorporated by reference herein.
