On August 8, 2018, Warrior Met Coal, Inc. (the “Company”) entered into an Underwriting Agreement (the “Underwriting Agreement”) with the selling stockholders named therein (the “Selling Stockholders”) and Morgan Stanley & Co. LLC, as underwriter (the “Underwriter”), pursuant to which the Selling Stockholders agreed to sell 2,204,806, shares of common stock, par value $0.01 per share, of the Company, to the Underwriter at a price of $25.40 per share (the “Offering”). The Offering closed on August 13, 2018. The Company did not receive any of the proceeds from the Offering.

The Underwriting Agreement contains customary representations, warranties and agreements of the Company and the Selling Stockholders and other customary obligations of the parties and termination provisions. The Company and the Selling Stockholders, in each case severally and not jointly, have agreed to indemnify the Underwriter against certain liabilities under the Securities Act of 1933, as amended (the “Securities Act”), or to contribute to payments the Underwriter may be required to make because of any such liabilities.

The Offering was made pursuant to the Company’s effective automatic shelf registration statement on Form S-3 (File No. 333-224734), filed with the Securities and Exchange Commission (the “SEC”) on May 8, 2018, and a prospectus, which consists of a base prospectus, filed with the SEC May 8, 2018, a preliminary prospectus supplement, filed with the SEC on August 8, 2018, and a final prospectus supplement, filed with the SEC on August 10, 2018.

The Underwriter and its affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for the Company, for which they received or will receive customary fees and expenses. Further, the Underwriter and its affiliates are lenders under or provided to the Company services in connection with the Company’s asset-based revolving credit agreement (the “ABL Facility”). Morgan Stanley Senior Funding, Inc., an affiliate of the Underwriter, serves as a lender under the ABL Facility.

The preceding summary of the Underwriting Agreement is qualified in its entirety by reference to the full text of such agreement, a copy of which is attached as Exhibit 1.1 hereto and incorporated herein by reference.
