Item 8.01. Other Events.

On February 23, 2017, DuPont Fabros Technology, Inc. (the “Company”) entered into separate equity distribution agreements (each, individually, an “Equity Distribution Agreement” and collectively, the “Equity Distribution Agreements”) with each of KeyBanc Capital Markets Inc., Robert W. Baird & Co. Incorporated, Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc., Goldman, Sachs & Co., Raymond James & Associates, Inc., RBC Capital Markets, LLC, Stifel, Nicolaus & Company, Incorporated, SunTrust Robinson Humphrey, Inc. and TD Securities (USA) LLC (collectively, the “Sales Agents”), pursuant to which the Company may issue and sell, from time to time, through the Sales Agents its shares of common stock, par value $0.001 per share (the “Common Stock”), having an aggregate gross sales price of up to $200,000,000 (the “Securities”).

The Securities will be issued pursuant to a prospectus dated June 2, 2015 and a prospectus supplement filed with the Securities and Exchange Commission (the “SEC”) on February 23, 2017, in connection with one or more offerings of shares under the automatic shelf registration statement on Form S-3 (Registration No. 333-204635) filed with the SEC on June 2, 2015. Sales of the Securities made pursuant to the Equity Distribution Agreements, if any, may be sold by any method permitted by law deemed to be an “at the market” offering as defined in Rule 415 of the Securities Act of 1933, as amended (the “Securities Act”), including, without limitation, directly on the New York Stock Exchange, or any other existing trading market for the Securities or through a market maker, or, if agreed by the Company and the Sales Agents, by any other method permitted by law, including but not limited to in privately negotiated transactions. The Company intends to use the net proceeds from these sales, if any, for general corporate purposes, which may include, without limitation, the repayment of borrowings under its unsecured revolving credit facility and its unsecured term loan, the construction of development properties, capital expenditures and working capital.

The Company made certain customary representations, warranties and covenants concerning the Company and the Securities in each Equity Distribution Agreement and also agreed to indemnify the Sales Agents against certain liabilities, including liabilities under the Securities Act. From time to time, the Company has had customary commercial and/or investment banking relationships with the Sales Agents and/or certain of their affiliates.

The foregoing description of the material terms of the Equity Distribution Agreements and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the full text of the Equity Distribution Agreements. Copies of the Equity Distribution Agreements are filed as exhibits 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9 and 1.10 to this Current Report on Form 8-K and incorporated herein by reference. The legal opinion relating to the Securities is included as Exhibit 5.1 hereto.

This Current Report on Form 8-K shall not constitute an offer to sell or a solicitation of an offer to buy any securities, nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or other jurisdiction.
