The Acquisition Playbook.

Three patterns run through Agnico Eagle Mines's acquisitions — what it looks for, how it pays, and how it folds in what it buys.

01
Acquisition criteria
Consolidating the Abitibi and Canada's Arctic.
Agnico repeatedly buys assets that sit next to its own operations or extend its home-region footprint. Cumberland's Meadowbank (2007) and Comaplex's Meliadine (2010) built its Nunavut platform and TMAC's Hope Bay (2021) deepened it, while the Osisko acquisition (2014), the Kirkland Lake merger (2021-2022) and the Yamana Canadian-assets deal (2022-2023) consolidated 100% of the Canadian Malartic mine and its position in the Abitibi gold belt, where it has operated for over 50 years.

02
Capital deployment
Buying development-stage ounces and applying its own build-and-operate skill.
Many targets were pre-production or early-stage deposits that Agnico framed as fits for its mine-development and Arctic operating expertise - Riddarhyttan's Suurikuusikko/Kittila deposit (2005), Grayd's La India project in Mexico (2011) and O3 Mining's Marban deposit (2024). Sean Boyd described Grayd as bringing 'our mine development and exploration skills to promising early stage gold deposits and projects.'

03
Integration approach
Friendly, board-supported deals with share-heavy consideration.
Agnico has favoured negotiated, board-recommended transactions and share-exchange offers over hostile bids: the Cumberland (0.185 share), Comaplex (0.1576 share) and Kirkland Lake (0.7935 share) deals were all-share, and the 2014 Osisko acquisition was a friendly agreement that topped Goldcorp's hostile bid. Where it pays cash, it still moves on board-supported terms, as with TMAC (2021) and O3 Mining (2024).

The Full Deal Book

9 acquisitions — each with the deal value, financing structure, target revenue, and executive commentary where disclosed.

01 Riddarhyttan Resources AB $150M
Disclosed in 8-K

Agnico Eagle agreed to make a share-exchange takeover offer for the balance of Riddarhyttan Resources AB, a Stockholm-listed explorer in which it already held about 14%. The offer valued Riddarhyttan at roughly US$150 million. Riddarhyttan's principal asset was the Suurikuusikko gold deposit in northern Finland, which Agnico developed into the Kittila mine - one of the largest gold mines in Europe. Agnico completed the acquisition later in 2005. ~US$150 million (whole-company value of the exchange offer; Agnico already owned ~14%).

02 Cumberland Resources Ltd. $710M
Disclosed in 8-K

Agnico Eagle agreed to acquire all of Cumberland Resources it did not already own through a share-exchange offer of 0.185 of an Agnico share per Cumberland share, valuing Cumberland at approximately C$710 million and representing about a 28.8% premium. Cumberland owned 100% of the Meadowbank gold project in Nunavut, then under construction with proven and probable reserves of about 2.9 million ounces. Meadowbank became Agnico's first mine in Nunavut. ~C$710 million (all-share; 0.185 Agnico share per Cumberland share).

The acquisition of Cumberland is expected to enhance our already significant gold production and reserve growth and is a logical next step in our strategy of building a premier international gold growth company. The transaction is expected to be accretive to our underlying net asset value, cash flow per share and reserves per share. Furthermore, we anticipate that the Meadowbank project's substantial reserve base will grow as we accelerate the exploration program in 2007.
03 Comaplex Minerals Corp. (Meliadine) Not disclosed
Disclosed in 8-K

Agnico Eagle agreed to acquire the shares of Comaplex Minerals it did not already own, giving each Comaplex shareholder 0.1576 of an Agnico share plus one share of a newly spun-out company (later Geomark) holding Comaplex's non-Meliadine assets. Total consideration was estimated at about C$10.32 per Comaplex share, roughly a 34% premium. Comaplex held 100% of the advanced-stage Meliadine gold project in Nunavut, about 300 km from Agnico's Meadowbank mine. Agnico completed the acquisition in July 2010. All-share exchange (0.1576 Agnico share per Comaplex share); total consideration ~C$10.32 per Comaplex share.

Upon completion of the proposed transaction, the addition of the large, high grade Meliadine property is consistent with our steady, focused approach to per share growth. In addition, on the back of a successful start up of our Meadowbank gold mine this quarter, the Meliadine property is a perfect fit with our Arctic skill set and the transaction solidifies our commitment to Nunavut and our foundation in Canada.
04 Grayd Resource Corporation $275M
Disclosed in 8-K

Agnico Eagle agreed to acquire all of Grayd Resource Corporation by take-over bid at C$2.80 per share, valuing the transaction at approximately C$275 million and a premium of about 65.7%. Grayd shareholders could elect cash or a mix of cash and Agnico shares, with total cash capped at about one third of consideration. Grayd owned 100% of the La India project in Sonora, Mexico, about 70 km from Agnico's Pinos Altos mine; La India later became a producing Agnico mine. ~C$275 million (take-over bid; C$2.80 per share cash-or-share option).

This acquisition is consistent with our long-term strategy of building value by bringing our mine development and exploration skills to promising early stage gold deposits and projects. The Grayd properties will benefit from the construction and operating experience gained at our Pinos Altos mine.
05 Osisko Mining Corporation (Canadian Malartic, 50% with Yamana Gold) $3.9B
Disclosed in 8-K

Agnico Eagle and Yamana Gold agreed to jointly acquire 100% of Osisko Mining for total consideration of about C$3.9 billion, or C$8.15 per share, through a 50/50 joint acquisition entity. Consideration comprised roughly C$1.0 billion cash, about C$2.33 billion in Agnico and Yamana shares, and shares of a newly created 'Spinco' (Osisko Gold Royalties). Osisko's flagship was the Canadian Malartic mine in Quebec, one of Canada's largest gold mines, which the two companies then jointly operated. The friendly agreement topped a hostile bid from Goldcorp. C$3.9 billion total (~C$8.15 per share); Agnico Eagle and Yamana each acquired 50%.

Agnico Eagle has approximately 50 years of operating history in Quebec, and over that time the company has continued to expand its mining presence in a measured and systematic way. This transaction further enhances our Quebec operating platform through the addition of a fourth producing mine. With this acquisition, Agnico Eagle will become Quebec's largest gold producer, which demonstrates our commitment to Quebec and various stakeholders in the Province.
06 TMAC Resources Inc. (Hope Bay) $286.6M
Disclosed in 8-K

Agnico Eagle agreed to acquire all of TMAC Resources for C$2.20 per share in cash, a total equity value of about C$286.6 million, after the Canadian government blocked TMAC's earlier proposed sale to China's Shandong Gold on national-security grounds. Agnico stepped in by taking assignment of the existing arrangement agreement at a raised price (a ~26% premium to Shandong's C$1.75). TMAC owned the Hope Bay gold operation in Nunavut's Kitikmeot region. Agnico also agreed to retire TMAC's outstanding debt; the deal closed in early February 2021. ~C$286.6 million (C$2.20 per share cash; plus retirement of TMAC debt).

We are very pleased to have the opportunity to bring our extensive northern operational and community experience to the Hope Bay Mine and the Kitikmeot Region of Nunavut. Together with the TMAC team and our Nunavut partners, we look forward to advancing exploration and expansion initiatives to realize the full potential of the Mine and its large unexplored land package.
07 Kirkland Lake Gold Ltd. (merger of equals) $209.3M
Disclosed in 8-K

Agnico Eagle and Kirkland Lake Gold agreed to combine in an all-stock merger of equals, with Kirkland Lake shareholders receiving 0.7935 of an Agnico share per Kirkland share and the combined company keeping the Agnico Eagle name. The deal implied a combined market capitalization of about US$24 billion, with legacy Agnico and Kirkland holders owning roughly 54% and 46%. It brought Kirkland's Detour Lake and Macassa mines in Ontario and the high-grade Fosterville mine in Australia into Agnico. The merger completed on February 8, 2022, with about 209.3 million Agnico shares issued to former Kirkland holders. All-stock merger of equals: 0.7935 Agnico share per Kirkland Lake share; ~209.3 million Agnico shares issued; combined market capitalization ~US$24 billion (Kirkland Lake holders received ~46%, implying ~US$11 billion).

This merger starts a new chapter in Agnico Eagle's 64-year history and creates the leading low risk global gold company with growing production, low costs and strong ESG leadership. The transaction creates a company with a strong platform of people, assets and financial resources to continue to build and operate a long term sustainable and self funding business... with this transaction we are well positioned to take advantage of high-quality opportunities and be a true Canadian mining champion.
08 Yamana Gold - Canadian assets (with Pan American Silver) $1.0B
Disclosed in 8-K

Agnico Eagle teamed with Pan American Silver on a definitive binding offer to acquire Yamana Gold, under which Pan American took Yamana's shares while Agnico acquired the subsidiaries holding Yamana's Canadian assets - most importantly the remaining 50% of the Canadian Malartic mine. Agnico's contribution was US$1.0 billion in cash plus about 36.1 million Agnico shares; the combined offer valued Yamana at roughly US$5.02 per share. Yamana's board deemed it a 'Superior Proposal' over an earlier all-stock Gold Fields agreement. The arrangement completed on March 31, 2023, giving Agnico 100% of Canadian Malartic plus the Wasamac project and other Abitibi exploration ground. Agnico contributed US$1.0 billion cash + 36,089,907 Agnico shares (part of the ~US$4.8 billion joint Pan American/Agnico acquisition of Yamana; ~US$5.02 per Yamana share).

This transaction is a continuation of Agnico Eagle's strategy to operate in regions where we believe we have a competitive advantage, in this case over 50 years of operating history. The full integration of the Canadian Malartic team and landholdings into our operational base in the region would enhance our Abitibi operating platform, placing Agnico in the unique position to further optimize the asset and unlock potential value through exploration and the leveraging of existing infrastructure, people and regional relationships.
09 O3 Mining Inc. $204M
Disclosed in 8-K

Agnico Eagle agreed to acquire all of O3 Mining by friendly all-cash take-over bid at C$1.67 per share, a ~57-58% premium, valuing the offer at about C$204 million. The bid was unanimously recommended by O3 Mining's board and backed by shareholders including Gold Fields. O3's principal asset was the Marban Alliance property near Agnico's Canadian Malartic complex in Quebec. Agnico took up about 95.6% of shares by early February 2025 and moved to acquire the remainder by amalgamation. ~C$204 million (C$1.67 per share cash; friendly take-over bid).

Consistent with our regional strategy, this transaction is a tuck-in of the Marban deposit to our Canadian Malartic complex. The Marban deposit is expected to be complementary to other 'Fill-the-Mill' opportunities at Canadian Malartic, further improving the production profile at a long-life world class asset.
