Hudbay Completes Acquisition of Copper Mountain to Create a Premier Americas-Focused Copper Producer

TORONTO, June 20, 2023 (GLOBE NEWSWIRE) — Hudbay Minerals Inc. (“Hudbay”) (TSX, NYSE: HBM) is pleased to announce that it has closed its previously announced court-approved plan of arrangement with Copper Mountain Mining Corporation (“Copper Mountain”), pursuant to which Hudbay has acquired all of the issued and outstanding common shares of Copper Mountain effective as of today’s date (the “Transaction”). Copper Mountain is now a wholly-owned subsidiary of Hudbay and, in accordance with the terms of the Transaction, former Copper Mountain shareholders received 0.381 of a Hudbay share for each Copper Mountain share previously held.

The Transaction creates a premier Americas-focused copper mining company that is well-positioned to deliver sustainable cash flows from an operating portfolio of three long-life mines, as well as compelling organic growth from a world-class pipeline of copper expansion and development projects. All assets in the combined portfolio are located in the tier-one mining-friendly jurisdictions of Canada, Peru and the United States. The combined company represents the third largest copper producer in Canada based on 2023 estimated copper productionⁱ.

Peter Kukielski, Hudbay’s President and Chief Executive Officer, commented, “We look forward to the formal integration of Copper Mountain into our complementary portfolio of operating assets. By applying our technical expertise, we expect to unlock significant annual operating efficiencies and synergies at the mine to drive further value for shareholders. This transaction creates a larger, more resilient operating platform that enhances our copper exposure, accelerates our deleveraging efforts, and positions us to more efficiently allocate capital to prudently advance our enviable organic growth pipeline.”

Leadership Additions

In connection with the closing of the Transaction, Hudbay has appointed Jeane Hull and Paula Rogers to its board of directors.

Jeane Hull has over 35 years of operational leadership and engineering experience, most notably holding the positions of Executive Vice President and Chief Technical Officer of Peabody Energy Corporation and Chief Operating Officer for Kennecott Utah Copper Mine, a subsidiary of Rio Tinto plc.

Paula Rogers has over 25 years of experience working for Canadian-based international public companies in the areas of corporate governance, treasury, mergers and acquisitions, financial reporting and tax. Ms. Rogers has been an officer of several public companies including Vice-President, Treasurer of Goldcorp Inc. and Treasurer of Wheaton River Minerals Ltd.

The experience, skills and perspectives of each of the new directors will complement the composition of Hudbay’s board and provide strengthened stewardship for the combined company.

Hudbay has also further bolstered the strength of its management team with the addition of Letitia Wong who will lead integration and Richard Klue as Vice President, Engineering Studies, in addition to benefiting from other members of the Copper Mountain team that are continuing with the combined company. As previously planned, Gil Clausen, Copper Mountain’s President and Chief Executive Officer, has retired and will transition to an advisory role for the combined company for the next year.

Strengthened Position as a Result of the Transaction

The combination of Hudbay and Copper Mountain is on-strategy with strong industrial logic that is expected to deliver compelling benefits, as highlighted below:

• Scale – a larger-scale platform with three long-life operating mines with exploration and expansion upside, three large-scale development projects and one of the largest mineral resource bases among intermediate copper producers;

• Diversification – a geographically balanced portfolio in tier-one mining jurisdictions with approximately 55% of net asset value (“NAV”)ⁱⁱ estimated to be from North American assets and 45% of NAV estimated to be from South American assets;

• Copper-Focused – a copper-focused portfolio with expected 2023 copper production of more than 150,000 tonnes in the second quartile position on the copper cost curveⁱⁱⁱ, complemented by meaningful gold production;

• Efficiencies – an estimated US$30 million^iv per year of operating efficiencies and corporate synergies, including approximately US$20 million per year from operating cost reductions through the application of Hudbay’s operating efficiency practices to the Copper Mountain mine;

• Deleveraging – well-positioned for accelerated deleveraging in the near-term from increased diversification of cash flows and enhanced exposure to rising copper prices;

• Capital Allocation – an ability to maximize value from a larger organic growth pipeline by more efficiently allocating capital to projects that yield the highest risk-adjusted returns; the combined company’s greater cash flow generation and strong balance sheet will enhance the ability to advance brownfield expansion opportunities and prudently develop Hudbay’s Copper World project in Arizona, which is expected to deliver meaningful growth to the combined company; and

• Valuation Re-rating Potential – the strategic and financial benefits from the Transaction is expected to position the combined company for a valuation re-rating.
