On June 16, 2017, City Office REIT, Inc. (the “Company”) and City Office Operating Partnership, L.P. (the “Operating Partnership”) entered into Equity Distribution Agreements (the “Agreements”) with each of KeyBanc Capital Markets Inc., Raymond James & Associates, Inc. and BMO Capital Markets Corp., as managers (the “Managers”). Pursuant to the terms of the Agreements, the Company agreed to sell through the Managers, subject to the terms and conditions set forth in the Agreements, up to 6,000,000 shares of the Company’s common stock, par value $0.01 per share (the “common stock”), and up to 1,000,000 shares of the Company’s 6.625% Series A Cumulative Redeemable Preferred Stock, par value $0.01 per share (the “Series A Preferred Stock” and together with the common stock, the “Shares”). Sales of Shares pursuant to the Agreements, if any, may be made in privately negotiated transactions and/or sales deemed to be an “at the market” offering as defined in Rule 415 of Securities Act of 1933, as amended, including, without limitation, sales made directly on the New York Stock Exchange or sales made to or through a market maker other than on an exchange. The Agreements contain customary representations, warranties and agreements of the Company, conditions to closing, indemnification rights and obligations of the parties and termination provisions.

The preceding description of the Agreements is qualified in its entirety by reference to the text of the Agreements, copies of which are attached hereto as Exhibit 1.1, Exhibit 1.2 and Exhibit 1.3 to this Current Report on Form 8-K and are incorporated herein by reference into this Item 1.01.

The Company expects to contribute any net proceeds from the sale of the Series A Preferred Stock in the offering to the Operating Partnership in exchange for the same number of Series A Preferred Units. The Series A Preferred Units have economic terms that mirror the terms of the Series A Preferred Stock. The issuance of the Series A Preferred Units will be exempt from registration pursuant to Section 4(a)(2) of the Securities Act.
