TORONTO, ONTARIO–(Marketwired – Aug. 17, 2016) –

NOT FOR DISTRIBUTION TO UNITED STATES NEWS WIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

Slate Office REIT (TSX:SOT.UN) (the “REIT”), a leading owner of office properties in Canada, announced today its intention to purchase a government-tenanted office building located at 365 Hargrave Street in Winnipeg, Manitoba (the “Hargrave Acquisition”) for $12.25 million. The REIT is also increasing its interest in three office properties located in St. John’s, Newfoundland (the “Places”) from 49% to 100%, with an additional investment of approximately $19.8 million (the “Places Investment”, and together with the Hargrave Acquisition, the “Acquisitions”). The Acquisitions are expected to close by the end of the third quarter of 2016.

In conjunction with the Acquisitions, the REIT also announced today that it has entered into an agreement with a syndicate of underwriters co-led by TD Securities Inc. and BMO Capital Markets (the “Underwriters”), to sell on a bought deal basis 6,000,000 trust units of the REIT (“Units”) at a price of $8.45 per Unit for gross proceeds of $50 million (the “Offering”).

The Offering consists of a treasury offering by the REIT of 5,204,500 Units for gross proceeds of $44.0 million (the “Treasury Offering”) and a secondary offering by Subcore Equities Inc., a private corporation managed by Greystone Managed Investments Inc. on behalf of certain pension fund clients, (the “Selling Unitholder”) of 795,500 Units for gross proceeds of $6.7 million (the “Secondary Offering”). Following the Offering, the Selling Unitholder will no longer hold an interest in the REIT. The REIT has also granted the Underwriters an over-allotment option to purchase up to an additional 15% of the Offering on the same terms and conditions, exercisable at any time, in whole or in part, up to 30 days after the closing of the Offering. The over-allotment option, if exercised, will be satisfied through the sale of Units from the REIT.

The REIT will use the net proceeds of the Treasury Offering to reduce outstanding indebtedness (which will be subsequently redrawn and applied as needed to pay a portion of the purchase price of the Acquisitions, for funding of future acquisitions and for general trust purposes). The REIT will not receive any proceeds from the Secondary Offering.

The Units will be offered in all provinces and territories of Canada by way of a short form prospectus. The Offering is subject to the receipt of all necessary regulatory and stock exchange approvals, including the approval of the TSX. Closing of the Offering is expected to occur on or about September 7, 2016.

“There are significant opportunities to make acquisitions today that meet the REIT’s investing criteria – well located, performing assets in markets with strong operating fundamentals.” said Scott Antoniak, the REIT’s Chief Executive Officer. “The REIT’s acquisition pipeline is robust and we continue to see significant opportunities to grow our portfolio.”
