Consolidated production reached 27,929 tonnes of copper and 61,700 ounces of gold, supporting record adjusted EBITDA of $421.9 million. Cash cost and sustaining cash cost, net of by-product credits, fell to record lows of $(1.80) and $0.00 per pound of copper, reflecting strong by-product pricing and tight cost control.

Hudbay closed a strategic joint venture at Copper World, recording $581.5 million of consideration and creating a $461.6 million non-controlling interest. Cash and cash equivalents increased to $1,003.8 million, total liquidity to $1,429.0 million, and net debt dropped to $5.6 million, leaving the net debt to adjusted EBITDA ratio at 0.0x. The company reaffirmed its 2026 copper and gold production and cost guidance.

Hudbay Minerals Inc. is calling a fully virtual annual and special shareholder meeting for May 19, 2026. The agenda includes receiving audited financial statements for 2024 and 2025, electing nine directors, appointing Deloitte LLP as auditor and holding a non-binding "say on pay" vote on executive compensation.

The circular describes how shareholders can vote by proxy or online under a notice-and-access model and outlines detailed governance practices. A letter from the Board Chair highlights 2025 results, including revenue of US$2.2 billion, adjusted EBITDA of US$1.1 billion and free cash flow of US$388 million, plus a sale of a 30% interest in the Copper World project to Mitsubishi for US$600 million and a reduced net debt to adjusted EBITDA ratio of 0.4x at year-end 2025.

Hudbay Minerals updates its mineral reserves and three-year outlook, showing longer mine lives and higher copper and gold output from Constancia, Snow Lake and Copper Mountain. Consolidated copper production is guided to average 147,000 tonnes annually over the next three years, up 24% from 2025, with gold averaging 243,000 ounces.

The company extends Constancia’s expected mine life to 2040, Snow Lake to 2041 and Copper Mountain to 2045, supported by mill upgrades and higher grades. Hudbay also advances its Copper World project in Arizona, highlighting 385 million tonnes of 0.54% copper reserves and Phase I production of 85,000 tonnes per year.

A $600 million Copper World joint venture with Mitsubishi provides $420 million upfront and $180 million within 18 months, lifting Hudbay’s post-closing cash and cash equivalents to $992 million and reducing its post-closing net debt to adjusted EBITDA ratio to 0.0x. CEO and CFO certifications and an amended LLC agreement formalize governance and funding for the Copper World vehicle.

Hudbay Minerals Inc. filed its Annual Report on Form 40-F, incorporating its Annual Information Form, audited consolidated financial statements for the years ended December 31, 2025 and 2024, Management's Discussion & Analysis, and mine safety disclosure.

Management concluded that disclosure controls and procedures were effective as of December 31, 2025, and Deloitte LLP issued an unqualified opinion on the Registrant's internal control over financial reporting and on the audited financial statements. The filing states there were no blackout periods during the year and discloses 395,521,903 common shares outstanding as of December 31, 2025.

HBM: A Form 144 notice lists an affiliate sale of 7,500 Common Shares through Morgan Stanley ETrade on the NYSE, showing an aggregate dollar amount of $155,625.00 and a filing date of 03/13/2026.

The filing also records prior transactions on 03/19/2020 (2,500 shares) and 03/20/2020 (5,000 shares) described as open market purchases. The notice documents a proposed resale by an affiliate; cash‑flow treatment is not specified in the excerpt.

Hudbay Minerals Inc. plans to acquire Arizona Sonoran Copper Company through a share‑for‑share deal. Each ASCU common share will be exchanged for 0.242 Hudbay common shares under a court‑approved plan of arrangement in British Columbia.

Based on Hudbay’s TSX closing price on February 27, 2026, the consideration equals about C$9.35 per ASCU share and an implied US$1.48 billion equity value for ASCU. After closing, existing Hudbay shareholders are expected to own roughly 89% of the combined company and former ASCU shareholders about 11%.

The transaction requires multiple approvals, including ASCU securityholder votes, Canadian and U.S. regulatory clearances, TSX and NYSE listing approvals for new Hudbay shares, and court approval. It is expected to close in the second quarter of 2026, after which ASCU shares will be delisted from the TSX and ASCU will seek to cease being a reporting issuer in Canada.
