Item 1.01. Entry into a Material Definitive Agreement.

On August 7, 2015, Gladstone Land Corporation, a Maryland corporation (the “Company”) and its operating partnership, Gladstone Land Limited Partnership, a wholly-owned, consolidated subsidiary of the Company and a Delaware limited partnership (the “Operating Partnership”), entered into separate Controlled Equity Offering Sales agreements (each a “Sales Agreement” and collectively the “Sales Agreements”) with Cantor Fitzgerald & Co. (“Cantor”) and Ladenburg Thalmann & Co. Inc. (“Ladenburg”), pursuant to which the Company may sell shares of the Company’s common stock, par value $0.001 per share, having an aggregate offering price of up to $30,000,000 (the “Shares”), from time to time through Cantor and Ladenburg, acting as sales agents and/or principals (each a “Sales Agent” and, collectively, the “Sales Agents”).

Pursuant to the Sales Agreements, the Shares may be offered and sold through each Sales Agent, acting separately, in transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act of 1933, as amended, including sales made directly on The NASDAQ Global Market or sales made to or through a market maker other than on an exchange or, subject to the terms of a written notice from the Company, by any other method permitted by law, including in privately negotiated transactions. Under the Sales Agreements, each Sales Agent will be entitled to compensation equal to up to 2.0% of the gross proceeds of the Shares it sells from time to time under its respective Sales Agreement. Subject to the terms and conditions of the respective Sales Agreements, the Sales Agents will use their commercially reasonable efforts to sell on the Company’s behalf any Shares to be offered by the Company under each Sales Agreement. The Company has no obligation to sell any of the Shares under the Sales Agreements, and the Company or each Sales Agent may at any time suspend solicitations and offers under the respective Sales Agreements.

The Shares will be issued pursuant to the Company’s Registration Statement on Form S-3 (File No. 333-194539) (the “Registration Statement”). The Company will file a prospectus supplement, dated August 7, 2015, to the prospectus, dated April 2, 2014, with the Securities and Exchange Commission in connection with the offer and sale of the Shares.

The Company expects to engage in investment banking, brokerage and other dealings with the Sales Agents and their affiliates in the ordinary course of business and to pay customary fees and commission for their services on those transactions.

The foregoing description of each Sales Agreement is not complete and is qualified in its entirety by reference to each Sales Agreement, copies of which is attached hereto as Exhibit 1.1 and Exhibit 1.2 and incorporated herein by reference.

In connection with the filing of the Sales Agreements, the Company is filing as Exhibit 5.1 to this Current Report on Form 8-K the opinion of Venable LLP, its Maryland counsel.
