Item 1.01 Entry into a Material Definitive Agreement.

On October 10, 2014, Energy West Incorporated, a Montana corporation (“EWI”) and a wholly-owned subsidiary of Gas Natural Inc. (the “Corporation”), executed a stock purchase agreement (the “Stock Purchase Agreement”) for the sale of all of the stock of its wholly-owned subsidiary, Energy West Wyoming, Inc., a Wyoming corporation (“EWW”), to Cheyenne Light, Fuel and Power Company, a Wyoming corporation (“Cheyenne”). The purchase price for EWW is $15,800,000, subject to adjustment based upon (i) the working capital of EWW on the closing of the transaction and (ii) any amendments to the disclosure schedules to the Stock Purchase Agreement that result in losses to EWW.

Also on October 10, 2014, Energy West Development, Inc., a Montana corporation (“EWD”) which is wholly-owned by EWI, executed an asset purchase agreement (the “Asset Purchase Agreement”) for the sale of the transmission pipeline system known as the Shoshone Pipeline and the gathering pipeline system known as the Glacier Pipeline and certain other assets directly used in the operation of the pipelines (collectively, the “Pipeline Assets”) to Black Hills Exploration and Production, Inc., a Wyoming corporation and an affiliate of Cheyenne (together, with Cheyenne, “Buyer”). The purchase price for the Pipeline Assets is $1,200,000, subject to adjustment based on any amendments to the disclosure schedules to the Asset Purchase Agreement that result in losses to the Pipeline Assets.

The Stock Purchase Agreement and the Asset Purchase Agreement are referred to collectively as the “Purchase Agreements” and all of the transactions contemplated therein are collectively referred to as the “Transaction.”

The Purchase Agreements contain customary representations, warranties, covenants and indemnification provisions. The consummation of the Transaction depends upon the satisfaction or waiver of a number of customary closing conditions, the receipt of regulatory approvals and the consent of certain of EWI’s lenders. In addition, Buyer has the right to terminate the Purchase Agreements in the event that the amendments to the disclosure schedules to the Purchase Agreements are reasonably likely to result in losses to EWW and the Pipeline Assets, collectively, in excess of $750,000.

The Transaction is expected to close in approximately six to twelve months but there can be no assurances that the Transaction will be completed on the proposed terms or at all.

The foregoing description of the Purchase Agreements is not complete and is qualified in its entirety by reference to the full and complete terms of the Purchase Agreements, which are attached to this Current Report on Form 8-K as Exhibits 10.1 and 10.2 and are incorporated herein by reference. The Corporation also issued a press release announcing this transaction on October 14, 2014. The press release is attached hereto as Exhibit 99.1.

Item 9.01 Financial Statements and Exhibits.

(d) Exhibits.
