Amerigo Resources Ltd. (TSX: ARG) (OTCQX: ARREF) reports financial results for the quarter ended June 30, 2026 and announces the declaration of its quarterly dividend. Dollar amounts in this news release are in U.S. dollars unless indicated otherwise.

Amerigo generated net income of $18.3 million, EBITDA¹ of $38.4 million, operating cash flow from operations before changes in non-cash working capital¹ of $26.7 million and free cash flow¹ of $21.9 million in Q2-2026.

“Q2-2026 was another strong financial quarter for Amerigo. Net income increased to $18.3 million, EBITDA¹ was $38.4 million, and free cash flow¹ was $21.9 million. Cash cost¹ was $1.74 per pound, or $1.60 per pound excluding the one-time signing bonus associated with the Minera Valle Central (“MVC”) supervisors’ collective agreement. These results demonstrate our ability to convert operating performance into earnings and cash flow, which we return to shareholders as quickly as possible,” said Aurora Davidson, Amerigo’s President and CEO.

“Generating cash flow is only part of the equation. We focus on converting that cash flow into shareholder value. During the first half of 2026, we returned $41.7 million to shareholders while increasing our cash balance by $10.0 million to $50.3 million. We also reduced shares outstanding through buybacks, enhancing per-share value while maintaining balance sheet strength. Since October 2021, Amerigo has returned $140.2 million to shareholders and reduced shares outstanding by 15.1%.”

“While copper prices remain volatile from quarter to quarter, we continue to view the long-term outlook constructively. Electrification, grid investment and renewable energy development continue to support demand growth. In contrast, supply growth remains increasingly challenged. For the balance of 2026, our priorities remain unchanged: safe and reliable operations, disciplined cost management, and maintaining the strength of our debt-free balance sheet. Flowing from this will be the consistent execution of our CRS, which will continue to prioritize the immediate return of excess cash to shareholders,” Ms. Davidson concluded.

Amerigo’s low sustaining capital requirements support a CRS that deploys quarterly dividends, performance dividends and share buybacks to quickly return excess cash to shareholders while maintaining balance sheet strength and financial flexibility.

On July 6, 2026, Amerigo’s Board of Directors declared a performance dividend of Cdn$0.18 per share, the largest in the Company’s history, bringing performance dividends declared year-to-date to Cdn$0.34 per share.

On July 27, 2026, the Board declared a quarterly dividend of Cdn$0.04 per share, payable on September 18, 2026, to shareholders of record as of August 28, 2026. Amerigo designates the full amount of this taxable dividend as an “eligible dividend” for purposes of the Income Tax Act (Canada), as amended from time to time.

The performance dividend payable on August 6, 2026, and the quarterly dividend payable on September 18, 2026, together represent approximately $25.0 million, or 50% of Q2-2026 ending cash.

Based on Amerigo’s June 30, 2026 share price of Cdn$6.14, the quarterly dividend represents an annualized yield of 2.6%. Including performance dividends declared year-to-date, shareholders have received a 2026 cash yield of 8.1%, demonstrating the significant contribution of performance dividends within Amerigo’s CRS.

Highlights and Significant Items

• The Company had strong production in Q2-2026, producing 16.9 million pounds (“M lbs”) of copper (Q2-2025: 15.5 M lbs), supported by excellent operational execution, 99.0% plant availability and a clean workplace safety record. The quarter also benefited from the strongest quarterly London Metal Exchange (“LME”) copper prices on record, resulting in an average copper price recognized by MVC of $6.16 per pound (“/lb”), compared to $4.42/lb in Q2-2025.

• In Q2-2026 net income was $18.3 million (Q2-2025: $7.5 million). Increases of $35.9 million in gross copper tolling revenue and $4.1 million in molybdenum revenue were offset by increases of $19.4 million in DET notional copper royalties, $6.4 million in tolling and production costs, $2.0 million in foreign exchange losses, and $8.0 million in income tax expense.

• Earnings per share (“EPS”) in Q2-2026 was $0.11 (Cdn$0.16), compared to $0.05 (Cdn$0.06) in Q2-2025.

• The Company generated operating cash flow before changes in non-cash working capital¹ of $26.7 million in Q2-2026, compared to $11.9 million in Q2-2025. Free cash flow¹ was $21.9 million in Q2-2026 (Q2-2025: $10.5 million).

• Q2-2026 cash cost¹ was $1.74/lb (Q2-2025: $1.82/lb). The $0.08/lb decrease in cash cost was primarily due to a $0.21/lb increase in molybdenum by-product credits, driven primarily by a 43% increase in molybdenum price. Normalized cash cost¹, which is cash cost excluding the effect of the signing bonus paid in the quarter to MVC’s supervisors under a three-year collective agreement, was $1.60/lb.

• On June 30, 2026, the Company held cash and cash equivalents of $50.3 million, compared with $40.3 million in cash and cash equivalents on December 31, 2025. Working capital (current assets less current liabilities) on June 30, 2026, was $9.7 million compared to $10.9 million on December 31, 2025.

• In Q2-2026, Amerigo paid $25.2 million to shareholders, including $18.7 million in performance dividends, $4.8 million in quarterly dividends and $1.7 million through share buybacks. Year-to-date 2026 payments to shareholders were $41.7 million, including $24.6 million in performance dividends, $9.5 million in quarterly dividends and $7.6 million in share buybacks. Amerigo had 295,451 fewer shares outstanding on June 30, 2026, than on December 31, 2025, reflecting the continued use of share buybacks alongside dividends to enhance per-share value.

• On June 30, 2026, Q2-2026 copper deliveries were marked-to-market to an average provisional price of $6.17/lb. The final prices for April, May and June 2026 copper deliveries will be the average LME prices for July, August, and September 2026, respectively. A 10% increase or decrease from the $6.17/lb provisional price used on June 30, 2026, would result in a $10.4 million change in revenue in the third quarter of 2026 regarding Q2-2026 copper deliveries.
