Cole Corporate Income Trust, Inc. (the “Company”) held a Special Meeting of Stockholders on January 27, 2015 (the “Special Meeting”). As of December 12, 2014, the record date for the Special Meeting, there were 197,605,729 shares of common stock issued and outstanding and eligible to be voted at the Special Meeting.

Proxies for the Special Meeting were solicited pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Set forth below are the voting results for the proposals considered and voted upon at the Special Meeting, all of which were described in the definitive Joint Proxy Statement/Prospectus filed by Select Income REIT (“SIR”) and the Company with the U.S. Securities and Exchange Commission (the “SEC”) on December 23, 2014.

The Company’s stockholders approved the merger of the Company with and into SC Merger Sub, LLC (“SIR Merger Sub”), a wholly owned subsidiary of SIR, with SIR Merger Sub surviving as a wholly owned subsidiary of SIR (the “Merger”), pursuant to that certain Agreement and Plan of Merger, dated as of August 30, 2014, as amended from time to time (the “Merger Agreement”), by and among the Company, SIR and SIR Merger Sub, and the other transactions contemplated by the Merger Agreement by the following vote:

Because the holders of a majority of the outstanding shares approved the proposal to approve the Merger and the other transactions contemplated by the Merger Agreement, the vote to approve the adjournment of the Special Meeting if there had not been sufficient votes to approve the Merger was not called.

No other proposals were submitted to a vote of the Company’s stockholders.

On January 27, 2015, the Company issued a press release, attached to this Current Report on Form 8-K as Exhibit 99.1 and incorporated herein by reference, announcing that stockholders of the Company have approved the Merger.

This Item 7.01 and the attached Exhibit 99.1 are provided under Item 7.01 of Form 8-K and are furnished to, and shall not be deemed to be “filed” with, the SEC.
