Hudbay Minerals Inc. has agreed to acquire all remaining shares of Arizona Sonoran Copper Company in an all-share transaction, offering 0.242 Hudbay share per ASCU share. This values ASCU at approximately C$9.35 per share, a 30% premium to its February 27, 2026 closing price, and about US$1,480 million in equity value.
The deal will give Hudbay 100% of the Cactus copper project in Arizona, creating a major copper district alongside its Copper World project. Hudbay expects to scale annual copper production from roughly 125,000 tonnes today to more than 250,000 tonnes by 2030 with Copper World and other near-term projects, and potentially beyond 350,000 tonnes including Cactus.
Hudbay and ASCU boards unanimously approved the arrangement, which requires multiple shareholder approvals, court and regulatory clearances and is expected to close in the second quarter of 2026. After closing, Hudbay shareholders will own about 89% of the combined company and ASCU shareholders about 11%.
