• Royalty Interests: The company acquires a contractual right to receive a percentage of the revenue or production from a mining asset, providing capital to the mine operator.
• Stream Interests: Metalla provides upfront capital to mining companies in exchange for the right to purchase a portion of future production (e.g., gold, silver) at a predetermined low price.

Major Customers of Metalla Royalty & Streaming (MTA)

Metalla Royalty & Streaming (MTA) operates on a business model where it acquires royalties and streams on metal production from other mining companies or royalty holders. As such, Metalla does not have "customers" in the traditional sense who purchase goods or services directly from them.

Instead, Metalla's revenue is generated from its ownership interests in these royalties and streams, which pay out based on the production from the underlying mines. Therefore, Metalla's financial performance is directly dependent on the production and operational success of the companies that operate the mines in its portfolio. While these entities are not direct "customers" buying products from Metalla, they are the critical operating partners whose mining activities drive Metalla's revenue streams.

Based on Metalla's portfolio of significant producing royalties and streams, the major operating companies whose mining activities are the primary source of Metalla's revenue include:

• Barrick Gold (NYSE: ABX)
• Newmont Corporation (NYSE: NEM)
• Agnico Eagle Mines Limited (NYSE: AEM)
• Karora Resources Inc. (TSX: KRR)
• Sandfire Resources Ltd (ASX: SFR)

• SSR Mining Inc. (SSRM)
• Teck Resources Limited (TECK)
• Osisko Mining Inc. (OSK.TO)
• McEwen Mining Inc. (MUX)
• SilverCrest Metals Inc. (SIL)

Metalla Royalty & Streaming (MTA) is expected to drive future revenue growth over the next 2-3 years through several key factors:

1. Commencement and Ramp-Up of New Production Royalties: Metalla anticipates significant revenue contributions from several projects transitioning into or ramping up production. The Endeavor Mine is expected to recommence operations with initial royalty payments in Q3 2025 and a full-year commercial run rate by 2026. Additionally, the Amalgamated Kirkland project is guided to begin production in Q4 2025, with a substantial ramp-up into 2026, projecting 50,000 to 60,000 ounces of gold in 2026 and 2027. The La Parrilla project also holds potential for production to start in the first half of 2026. The Tocantinzinho project, which reached commercial production in Q3 2024, is expected to generate approximately 1,000 gold equivalent ounces in 2025 and between 2,500 and 3,000 gold equivalent ounces from 2026 through 2028.

2. Resource Expansion and Integration at Key Development-Stage Projects: The Côté/Gosselin project is a major driver, with Metalla having increased its royalty to 1.5% in November 2025. IAMGOLD Corporation, the operator, plans extensive drilling at Gosselin in 2025 (45,000 meters) and expects an updated reserves/resources and technical report by year-end 2026, which is anticipated to significantly boost value by 2026-2027 through the integration of Gosselin into the Côté mine plan. Furthermore, the Wharf Mine has seen a substantial increase in its measured, indicated, and inferred mineral resources, positioning it for significant mine life extensions. The Aranzazu project has also extended its mine life to a decade, ensuring continued revenue.

3. Strategic Acquisitions and Portfolio Growth: Metalla has a stated goal of pursuing larger, cash-flowing acquisitions to potentially reach over $100 million in annual revenue by the end of the decade. The company's portfolio, including assets acquired through the C$500 million Nova Royalty deal in late 2023, boasts 105 royalties and streams with long asset lives and increased exposure to copper. This robust pipeline, with 88% of its value in development, supports a projected 30-35% compound annual growth rate in revenue or gold equivalent ounces between now and the end of the decade.

4. Favorable Commodity Price Environment: As a royalty and streaming company, Metalla inherently benefits from rising commodity prices, particularly for gold, silver, and copper. The business model provides leveraged exposure to these metals without the direct operational risks of mining. Management commentary often highlights the upside potential from higher precious metal prices, and a structural bull market for copper, forecasted to start in 2025 and last at least a decade, is expected to drive significant value.

• In late 2023, Metalla completed an all-stock acquisition of Nova Royalty Corp. valued at approximately C$180-190 million, issuing Metalla common shares to Nova shareholders.

• On December 21, 2022, the company completed the acquisition of eight royalties on exploration, development, and mining properties in Mexico from First Majestic Silver Corp. for $20 million in Common Shares.

Capital Expenditures

• Metalla's business model as a royalty and streaming company generally means lower direct capital expenditures compared to mining operators, as their focus is on acquiring interests rather than mine development.
• In the last 12 months (as of August 2025), Metalla reported capital expenditures of -$7.72 million.
• For the years ended December 31, 2024, and 2023, Metalla reported mineral expenditures and capital assets of approximately $2.06 million and $3.18 million (USD thousands), respectively.
