Osisko Announces Increase to Previously Announced Secondary Offering

MONTREAL, June 25, 2019 - Osisko Gold Royalties Ltd. ("Osisko" or the "Company") (TSX & NYSE: OR) is pleased to announce that, due to strong demand, Betelgeuse LLC ("Orion"), a jointly owned subsidiary of certain investment funds managed by Orion Resource Partners, has entered into a revised agreement with a syndicate of underwriters led by CIBC Capital Markets and BMO Capital Markets (the "Underwriters"), to increase the size of its previously announced bought deal offering to 7,850,000 common shares of Osisko ("Common Shares") held by Orion at an offering price of $14.10 per Common Share (the "Secondary Offering Price") for total gross proceeds to Orion of $110,685,000 (the "Secondary Offering"). Osisko will not be receiving any of the proceeds of the Secondary Offering. Amounts are in Canadian dollars unless otherwise noted.

Orion has granted the Underwriters an over-allotment option, exercisable at any time up to 30 days from and including the date of closing of the Secondary Offering, to purchase up to 1,177,500 Common Shares, at the Secondary Offering Price (the "Over-Allotment Option").

In a concurrent transaction, Osisko has agreed to purchase for cancellation 12,385,717 of its Common Shares from Orion (the "Share Repurchase"). The purchase price per Common Share to be paid by Osisko under the Share Repurchase will be the Secondary Offering Price. Payment from Osisko to Orion will consist of a combination of cash and the direct transfer of other equity securities currently held by Osisko. In a concurrent transaction, Osisko has also agreed to sell to separate entities managed by Orion Resource Partners certain other equity securities held by Osisko for cash.

Upon closing of the Secondary Offering and the Share Repurchase and prior to the exercise of the Over-Allotment Option, Orion's ownership of Osisko's issued and outstanding Common Shares will be reduced from 19.5% to 7.0%.

The Common Shares will be offered by way of a short form prospectus in all of the provinces of Canada and in the United States under the multi-jurisdictional disclosure system adopted by the United States and Canada. A preliminary short form prospectus and a registration statement on Form F-10 relating to the Secondary Offering have been filed with Canadian securities regulatory authorities and the U.S. Securities and Exchange Commission (the "SEC"), respectively.

Orion has agreed with the Underwriters that its remaining Common Shares will be subject to a 180 day lock-up period, subject to customary exceptions.

No securities regulatory authority has either approved or disapproved of the contents of this news release. This press release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the securities in any jurisdiction in which such offer, solicitation or sale would be unlawful.

The Company has filed a registration statement (including a prospectus) with the U.S. Securities and Exchange Commission (the "SEC") for the Secondary Offering. The Common Shares to be sold in the Secondary Offering described in this document may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. Before readers invest, they should read the prospectus in that registration statement and other documents the Company has filed with the SEC for more complete information about the Company and the Secondary Offering. The Company has also filed a preliminary short form prospectus relating to the Secondary Offering with each of the provincial securities regulatory authorities in Canada.

Special Committee Review Process

To review and evaluate the merits of the Share Repurchase and Concurrent Investment Disposition, the board of directors of Osisko established a special committee of independent directors (the "Special Committee"). Stikeman Elliott LLP acted as legal advisor to Osisko in connection with the Share Repurchase and Concurrent Investment Disposition and the Special Committee retained National Bank Financial Inc. as its independent financial advisor. The Special Committee undertook a deliberate and full consideration of the Share Repurchase and Concurrent Investment Disposition with the assistance of such advisors, and, upon the recommendation of the Special Committee that, among other things, the Share Repurchase and Concurrent Investment Disposition are in the best interests of Osisko, the board of directors of Osisko (other than one interested director who abstained from voting) unanimously approved the Share Repurchase and Concurrent Investment Disposition.

Orion is a "related party" of Osisko within the meaning of Multilateral Instrument 61‑101 ‑ Protection of Minority Security Holders in Special Transactions ("MI 61-101") since it holds Common Shares entitling it to more than 10% of the voting rights attached to all the issued and outstanding voting securities of Osisko. Therefore, the Share Repurchase and Concurrent Investment Disposition constitute "related party transaction" within the meaning of MI 61-101. Osisko is exempted from the formal valuation and minority approval requirements pursuant to MI 61-101 since neither the fair market value of the subject matter of, nor the fair market value of the consideration for, the Share Repurchase, together with the fair market value of the subject matter of, or the fair market value of the consideration for, the Concurrent Investment Disposition, represent more than 25% of the market capitalization of Osisko.
