The Consideration represents an approximate 55% premium to the 20‐day volume weighted average trading price per Share on the Toronto Stock Exchange (“TSX“) for the period ending August 9, 2024, being the last trading day prior to the announcement of the Transaction.

Osisko’s Chairman and Chief Executive Officer, John Burzynski, stated:

“This premium transaction represents a strong and near-term outcome for our shareholders and is reflective of the truly world class nature of the Windfall Project. In the span of nine years, we’ve transformed Windfall into one of the largest and highest-grade gold development projects globally, and this Transaction
is a testament to the extraordinary entrepreneurial effort of the Osisko Mining team. Gold Fields is a globally diversified senior gold producer with an impressive track record of successfully building and operating mines. As our joint venture partner at Windfall, Gold Fields knows the asset well and understands the significance of the strong relationships that we have built in Québec with all of our stakeholders. Moreover, Gold Fields share our core principles of operating in a safe, inclusive and socially responsible manner. They are well suited to take Windfall into production and we wish them all the best going forward.”

Gold Fields’ Chief Executive Officer, Mike Fraser, stated:

“We are pleased to consolidate the remaining 50% interest of the advanced-stage Windfall Project and its highly prospective exploration camp. Over the past two years, beginning with our initial due diligence in 2022 and throughout our joint ownership of the Project, since May 2023 with Osisko, we have developed a strong understanding of Windfall and its potential, and view it as the next long-life cornerstone asset in our portfolio.

We are excited to build on the progress achieved to date at Windfall and look forward to continue working with the host Cree First Nation of Waswanipi, other local communities, the Québec Government and Windfall employees and business partners as we advance this Project which I strongly believe will create shared, enduring value for Gold Fields and our people, community, business and government partners.”

The Transaction will be implemented by way of a statutory plan of arrangement under Section 182 of the Business Corporations Act (Ontario) (the “Plan of Arrangement“). Completion of the Transaction is subject to customary conditions, including, among others, court approval, regulatory approvals, the approval of at least two‐thirds of the votes cast by the Shareholders present in person or represented by proxy at the Meeting and a simple majority of the votes cast by Shareholders on a resolution approving the Arrangement, excluding for this purpose the votes attached to the Shares held by persons required to be excluded for purposes of Multilateral Instrument 61-101 – Protection of Minority Security Holders

In connection with the Transaction, each of the directors and executive officers of Osisko have entered into a voting support agreement (collectively, the “Voting Support Agreements“) with the Purchaser and Gold Fields Limited, pursuant to which they have agreed, among other things, to vote all of their Shares (including any Shares issued upon the exercise of any securities convertible, exercisable or exchangeable into Shares) in favour of the Transaction.

The Arrangement Agreement provides for customary deal protection provisions, including non-solicitation covenants of Osisko and “fiduciary out” provisions in favour of Osisko. In addition, the Arrangement Agreement provides for a termination fee of C$108 million payable by Osisko if it accepts a superior proposal and in certain other specified circumstances. Each of Osisko and the Purchaser have made customary representations and warranties and covenants in the Arrangement Agreement, including covenants regarding the conduct of Osisko’s business prior to the closing of the Transaction.

Pursuant to the terms of the Arrangement Agreement, each outstanding option to purchase common shares in the capital of Osisko (each, a “Company Option“) immediately prior to the effective time of the Arrangement shall be, and shall be deemed to be, unconditionally vested and exercisable and shall be deemed to be assigned and transferred by such holder to Osisko in exchange for a cash payment from Osisko equal to the Company Option in-the-money amount. Each such Company Option shall immediately be cancelled, and the holder shall cease to be a holder of such Company Option. Each deferred share unit and restricted share unit of Osisko granted under Osisko’s equity incentive plans outstanding immediately prior to the effective time of the Arrangement Agreement shall be deemed to be settled by Osisko in exchange for a cash payment from Osisko pursuant to the terms of the Arrangement Agreement. The C$154 million of 4.75% convertible senior unsecured debenture due December 1, 2025 will either be converted by the holder thereof for Shares in advance of the closing of the Transaction, or will be repaid in accordance with its terms.

Article content

The common share purchase warrants of the Company (the “Warrants“) issued on February 28, 2023, with an exercise price of C$4.00 per Share, are scheduled to expire on August 28, 2024. Any Shares issuable upon the exercise of such Warrants will be entitled to receive the Consideration of C$4.90 per Share pursuant to the Transaction.

Subject to the satisfaction of all conditions to closing set out in the Arrangement Agreement, it is anticipated that the Transaction will be completed in Q4 2024. Upon closing of the Transaction, it is expected that the Shares will be delisted from the TSX and that Osisko will cease to be a reporting issuer under applicable Canadian securities laws.

The foregoing summary is qualified in its entirety by the provisions of the respective documents.
