Underwriting Agreement

On June 21, 2016, QEP Resources, Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with J.P. Morgan Securities LLC and Deutsche Bank Securities Inc., each for itself and as a representative of the other underwriters named on Schedule A thereto (the “Underwriters”), which provides for the issuance and sale by the Company, and the purchase by the Underwriters, of an aggregate of 20,000,000 shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), at a price of $17.97 per share, after underwriting discounts and commissions. The Company also granted the underwriters a 30-day option to purchase up to an additional 3,000,000 shares of Common Stock (the “Option Shares”). On June 23, 2016, the Underwriters exercised in full their option to purchase the Option Shares, increasing the aggregate number of shares issued in connection with the offering to 23,000,000 shares of Common Stock. The Common Stock has been registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to the Company’s Registration Statement on Form S-3 (File No. 333-202686), which became effective upon filing with the Securities and Exchange Commission (the “Commission”) on March 12, 2015, and a prospectus, which consists of a base prospectus, filed with the Commission on March 12, 2015, a preliminary prospectus supplement, filed with the Commission on June 21, 2016, and a final prospectus supplement, filed with the Commission on June 22, 2016 (collectively, the “Prospectus”). The offering closed on June 27, 2016. The Company intends to use the net proceeds from the offering to partially fund the Company’s recently announced acquisition of oil and gas properties in the northern Midland Basin of the Permian Basin (the “Acquisition”). In the event the Acquisition does not close, the Company intends to use the net proceeds for general corporate purposes, which may include, among other things, reducing indebtedness, acquiring properties and funding a portion of the Company’s exploration and production activities and working capital.

The Underwriting Agreement contains customary representations, warranties and agreements by the Company, including obligations of the Company to indemnify the Underwriters for certain liabilities under the Securities Act. The foregoing description of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Underwriting Agreement, which is filed as Exhibit 1.1 to this Current Report on Form 8-K.

Relationships

As more fully described under the caption “Underwriting” in the Prospectus, the Underwriters and certain of their affiliates have provided from time to time, and may provide in the future, investment and commercial banking and financial advisory services to the Company and its affiliates in the ordinary course of business, for which they have received and may continue to receive customary fees and commissions.
