Hudbay Minerals (NYSE:HBM) and Arizona Sonoran Copper Company (ASCU) announced a definitive merger agreement on Monday, marking the creation of a massive new "copper district" in southern Arizona.
Hudbay has agreed to acquire all outstanding shares of ASCU it does not already own in an all-stock deal valued at approximately C$9.35 per share, representing a 30% premium to ASCU’s closing price on February 27, 2026.
The transaction, which implies a total equity value of approximately $1.48 billion, centralizes two of the most significant copper development assets in the United States: ASCU’s Cactus project and Hudbay’s Copper World.
By consolidating these neighboring sites, Hudbay aims to scale its annual copper production from approximately 125,000 tonnes today to over 350,000 tonnes by the end of the decade.
The move follows Hudbay’s recent strategic de-leveraging and the January 2026 closing of a $600 million joint venture with Mitsubishi Corporation for the development of Copper World.
The combined "Arizona Hub" is expected to generate significant operational synergies, including shared infrastructure and a unified approach to the solvent extraction and electrowinning (SX/EW) processing required to produce "Made in America" copper cathode for the domestic green energy supply chain.
