VANCOUVER, BC, Feb. 11, 2026 /PRNewswire/ - Metalla Royalty & Streaming Ltd. ("Metalla" or the "Company") (NYSE:MTA) (TSXV:MTA) is pleased to announce preliminary and unaudited results for the year ended 2025 and to provide the following recent developments in its royalty portfolio.

PRELIMINARY 2025 RESULTS

The Company expects to recognize record revenue from royalty and stream interests, including fixed royalty payments, of $11.7 million⁽¹⁾, representing a 99% increase compared to the $5.9 million in revenue from 2024.

The Company expects to receive or accrue payments on 3,436 attributable Gold Equivalent Ounces ("GEOs")⁽¹⁾, representing a 38% increase compared to the 2,481 GEOs from 2024, for the year ended December 31, 2025.  The Company had previously provided updated guidance that it expected to meet the lower end of its annual guidance range of 3,500 to 4,500 GEOs for 2025. Attributable GEOs for the fourth quarter and year were negatively impacted by ramp-up delays and a safety incident at Endeavor Mine and below internal forecasts at Wharf Mine.

Metalla expects to release its 2026 guidance on March 26, 2026, along with its full year audited financial statements.

Caution Regarding Pre-Released Financial Information

This news release contains certain pre-released fourth quarter and full year financial information. The fourth quarter and full year financial information contained in this news release are preliminary and unaudited and represent the most current information available to the Company's management, as financial closing procedures for the three months and year ended December 31, 2025 are not yet complete. The Company's actual consolidated audited financial statements for such period will be filed with the applicable Canadian securities administrators on its profile on SEDAR at https://www.sedarplus.ca/ and the SEC on its profile on EDGAR at www.sec.gov, and may result in material changes to the financial metrics summarized in this news release as a result of the completion of normal quarter and year-end accounting procedures and adjustments, and also what one might expect to be in the final consolidated financial statements based on the financial metrics summarized in this news release. Although the Company believes the expectations reflected in this news release are based upon reasonable assumptions, the Company can give no assurance that actual results will not differ materially from these expectations. In addition, our presentation of preliminary results does not include a presentation of expenses or net income (loss), which remain subject to completion of our year-end audit procedures.

Non-IFRS Financial Measures

Metalla has included a performance measure, attributable gold equivalent ounces (GEOs), in this press release that does not have any standardized meaning prescribed by International Financial Reporting Standards ("IFRS"). The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information to evaluate the Company's performance and ability to generate cash flow. Attributable GEOs are a non-IFRS financial measure that is composed of gold ounces attributable to the Company, calculated by taking the revenue earned by the Company in the period from payable gold, silver, copper and other metal ounces attributable to the Company divided by the average London fix price of gold for the relevant period. The Company presents attributable GEOs as it believes that certain investors use this information to evaluate the Company's performance in comparison to other streaming and royalty companies in the precious metals mining industry who present results on a similar basis. 

Technical and Third-Party Information

Metalla has limited, if any, access to the properties on which Metalla holds a royalty, stream or other interest. Metalla is dependent on (i) the operators of the mines or properties and their qualified persons to provide technical or other information to Metalla, or (ii) publicly available information to prepare disclosure pertaining to properties and operations on the mines or properties on which Metalla holds a royalty, stream or other interest, and generally has limited or no ability to independently verify such information. Although Metalla does not have any knowledge that such information may not be accurate, there can be no assurance that such third-party information is complete or accurate. Some information publicly reported by operators may relate to a larger property than the area covered by Metalla's royalty, stream or other interests. Metalla's royalty, stream or other interests can cover less than 100% and sometimes only a portion of the publicly reported mineral reserves, resources and production of a property. Ounces are converted to grams using a multiple of 31.1035.

Unless otherwise indicated, the technical and scientific disclosure contained or referenced in this press release, ‎including any ‎references to mineral resources or mineral reserves, was prepared in accordance with Canadian ‎NI 43-101‎, which differs significantly from the requirements of the U.S. Securities and ‎Exchange Commission (the "SEC") ‎applicable to U.S. domestic issuers. Accordingly, the scientific and technical ‎information contained or referenced in this press release may not be comparable to similar information made ‎public by U.S. companies subject to the reporting and ‎disclosure requirements of the SEC.

‎"Inferred mineral resources" have a great amount of uncertainty as to their existence and great uncertainty as to ‎their ‎economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ‎ever be ‎upgraded to a higher category. Historical results or feasibility models presented herein are not guarantees ‎or expectations of ‎future performance.‎
