Arizona Sonoran Securityholders Approve Hudbay Transaction with over 99% of Votes Cast FOR

The most recent release confirms that securityholders of Arizona Sonoran Copper Company Inc. (ASCU) have voted overwhelmingly in favor of the statutory plan of arrangement to acquire ASCU by Hudbay Minerals Inc. The voting results show 99.84% shareholder approval and 99.85% securityholder approval, exceeding the required thresholds for a transaction of this magnitude. Under the terms, shareholders receive 0.242 common shares of Hudbay for each ASCU share held. The transaction is expected to close in Q2 2026, subject to final regulatory and court approvals, with a Supreme Court hearing scheduled for May 14, 2026. Following completion, ASCU will be delisted from the TSX.

While shareholder approval is a critical milestone, this news is largely priced in given the March 2026 acquisition announcement which was rated "Material - Game Changer." The market has been trading ASCU at a discount to the implied offer value ($9.35/share) since the announcement, reflecting deal risk and exchange ratio volatility. This vote removes the shareholder uncertainty block but does not alter the fundamental economics of the transaction or the company's standalone prospects (which are now subsumed by Hudbay). The approval validates the path to closing but introduces a new binary event: the Supreme Court hearing on May 14, 2026. As the deal terms remain unchanged and the vote was anticipated following the ISS recommendation on May 4, this is an incremental confirmation rather than a value-creating surprise.

Arizona Sonoran Copper Company Inc. is an exploration and development company focused on the Cactus Project in Arizona. The project is a brownfield copper deposit with significant oxide resources suitable for heap leaching. Prior to acquisition, the company was advancing toward a Final Investment Decision (FID) by Q4 2026, targeting first production in H2 2029. The Pre-Feasibility Study (PFS) released in late 2025 showed strong economics with an NPV of $2.3 billion and IRR of 22.8%. With the acquisition by Hudbay, the Cactus Project will become part of a larger U.S. copper hub alongside Hudbay's Copper World project.
