On October 15, 2012, Mid-Con Energy Partners, LP (the “Partnership”) entered into, through one of its wholly-owned subsidiaries, a definitive purchase and sale agreement with Samson Resources Company to acquire certain oil properties located in our Hugoton Basin core area for a contract price of approximately $21 million, which included a performance deposit of $2.1 million, subject to closing conditions (the “Acquisition”). The Partnership anticipates that the Acquisition will close on or before November 6, 2012, and will be financed with existing cash and borrowings under our credit facility. There can be no assurance that all of the conditions to closing the Acquisition will be satisfied.

On October 15, 2012, the Partnership issued a press release announcing the Acquisition and the increase in quarterly distribution, a copy of which is furnished as Exhibit 99.1 and incorporated by reference herein. The Partnership also announced the commencement of an underwritten public offering of common units. A copy of the press release is furnished as Exhibit 99.2 and incorporated by reference herein. Additionally, on October 15, 2012, the Partnership confirmed that its previously released Boe production guidance for the third quarter of 2012 will come in within its previously released range, likely toward the lower end. A copy of the press release is furnished as Exhibit 99.1 and incorporated by reference herein.

On October 15, 2012, the board of directors of our general partner, Mid-Con Energy GP, LLC, approved a cash distribution of $0.485 per common unit for the third quarter 2012. This represents a $0.01 per common unit increase compared with the preceding quarter, and results in an annualized distribution of $1.94 per common unit. The third quarter distribution is payable on November 14, 2012 to unitholders of record as of November 7, 2012.

The information disclosed in Item 7.01 hereof, including Exhibits 99.1 and 99.2 hereto, is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the Exchange Act), or otherwise subject to the liabilities under that section, nor shall they be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act except as expressly set forth by specific reference in such filing.
