**Platinum Group Metals Ltd. Reports 2025 Annual Results**

(Vancouver/Johannesburg) **Platinum Group Metals Ltd.** (PTM:TSX; PLG:NYSE American) ("**Platinum Group**", "**PTM**" or the "**Company**") reports the Company's financial results for the fiscal year ended August 31, 2025, and provides an update and outlook. The Company's material property is the Waterberg project located on the Northern Limb of the Bushveld Complex in South Africa (the "**Waterberg Project**"). The Waterberg Project is planned as a fully mechanised, shallow, decline access platinum, palladium, rhodium and gold ("**4E**" or "**PGM**") mine, including by-product copper and nickel production, and is projected to be one of the largest and lowest cost underground platinum group metals ("**PGM**" or "**PGMs**") mines globally. The Company's near-term objectives are to advance the Waterberg Project to a development and construction decision, including the arrangement of construction financing and concentrate offtake agreements.

The Company has filed its audited consolidated financial statements (the "**Financial Statements**") for the year ended August 31, 2025, Annual Information Form ("**AIF**"), and Management's Discussion and Analysis ("**MD&A**") with Canadian securities regulators on SEDAR+ (<u>www.sedarplus.ca</u>). The Company has also filed a Form 40-F annual report ("**Form 40-F**"), including the Financial Statements, with the U.S. Securities and Exchange Commission (the "**SEC**") on EDGAR (<u>www.sec.gov</u>). Shareholders are encouraged to visit the Company's website at <u>www.platinumgroupmetals.net</u>. Shareholders may receive a hard copy of the complete Financial Statements and MD&A from the Company free of charge upon request.

All amounts herein are reported in United States dollars unless otherwise specified. The Company holds cash in Canadian dollars, United States dollars and South African Rand. Changes in exchange rates may create variances in the cash holdings or results reported.

**Project Ownership**

As of August 31, 2025, the Waterberg Project is owned by Waterberg JV Resources (Pty) Ltd. ("**Waterberg JV Co**."), which is in turn owned by Platinum Group (37.32%), Mnombo Wethu Consultants Proprietary Limited ("**Mnombo**") (26.0%), HJ Platinum Metals Company Ltd. ("**HJM**") (21.95%) and Impala Platinum Holdings Ltd. ("**Implats**") (14.73%). Platinum Group holds a further 12.97% indirect interest in Waterberg JV Co. through a 49.9% interest in Mnombo.

PLATINUM GROUP METALS LTD. …2

HJM was established in 2023 by Japan Organization for Metals and Energy Security ("**JOGMEC**") and Hanwa Co. Ltd. ("**Hanwa**") as a special purpose company to hold and fund their aggregate future equity interests in the Waterberg Project. The combined Waterberg JV Co. ownership of JOGMEC (12.195%) and Hanwa (9.755%) were consolidated into a 21.95% interest for HJM going forward, with JOGMEC to fund 75% of future equity investments into HJM and Hanwa the remaining 25%.

In calendar 2023, Implats implemented a group wide restriction on capital expenditures. As a result, since early 2024, Implats has not funded their share of Waterberg Project cash calls and their interest in Waterberg JV Co. has diluted by approximately 0.27%. Platinum Group has funded Implats shortfall and the Company's direct interest in Waterberg JV Co. has increased concurrently with Implats dilution. Implats has advised they will consider the funding of new cash calls as future circumstances allow.

**Recent Events**

**On September 17, 2025**, the board of directors of Waterberg JV Co. unanimously approved a sixth stage of work in the amount of Rand 92.1 million (approximately $5.11 million at the time) for fiscal year 2026, to allow for the continuation of work programs underway. The Stage Six Budget was subsequently approved by a consent resolution of the requisite majority shareholders on September 26, 2025. The interim budget covers the period ending August 31, 2026, and includes some components of a $21.0 million pre-construction work program approved in principle for the Waterberg Project by the directors and shareholders of Waterberg JV Co. on October 18, 2022 (the "**Pre-Construction Program**").

**On May 29, 2025**, Platinum Group reported the closing of a non-brokered private placement of common shares of the Company ("**Common Shares**") at a price of $1.26 per Common Share. An aggregate of 800,000 Common Shares were subscribed for and issued to existing major beneficial shareholder, Hosken Consolidated Investments Limited ("**HCI**") through its subsidiary Deepkloof Limited, resulting in gross proceeds to the Company of $1.0 million (the "**Private Placement**"). Closing of the Private Placement allowed HCI to return to a 26% interest in the Company at that time.

**On February 18, 2025**, the board of directors for Waterberg JV Co. unanimously approved a Rand 42 million interim budget (approximately $2.27 million at the time) to allow the continuation of work programs for the Waterberg Project. The interim budget covered the period ending August 31, 2025, and included some components of the Pre-Construction Program.

**On December 5, 2024**, the Company entered into an Equity Distribution Agreement with BMO Nesbit Burns Inc. and Beacon Securities Limited (the "**Canadian Agents**") and BMO Capital Markets Corp. (the "**U.S. Agent**" and together with the Canadian Agents, the "**Agents**") for a new at-the-market equity program (the "**2025 ATM**") to distribute up to $50.0 million (or the equivalent in Canadian dollars) of Common Shares (the "**Offered Shares**"). The Offered Shares will be issued by the Company to the public from time to time, through the Agents, at the Company's discretion. The Offered Shares sold under the 2025 ATM will be sold at the prevailing market price at the time of sale. The net proceeds of any such sales will be used for pre-construction site work, engineering and preparation, a potential first phase development program at the Waterberg Project, smelter and base metal refinery studies, a contingency provision and general, corporate and administrative expenses. Sales of Common Shares on the NYSE American pursuant to the 2025 ATM through the U.S. Agent commenced on January 22, 2025, and during the period ended August 31, 2025, 8,941,494 shares were sold at an average price of US$1.47 for gross proceeds of $13.2 million before directly attributable costs of $0.33 million. After August 31, 2025, to the date of this news release, the Company sold a further 3,728,000 shares at an average price of US$2.46 for gross proceeds of $9.16 million before deducting directly attributable costs of $0.23 million.

PLATINUM GROUP METALS LTD. …3

**On November 26, 2024**, the Company entered a memorandum of understanding (the "**MOU**") with Ajlan & Bros Company for Mining, a subsidiary of Ajlan & Bros Holding ("**Ajlan**"), and the Ministry of Investment of Saudi Arabia ("**MISA**") as a part of the Global Supply Chain Resilience Initiative, for the study of a proposed platinum group metals smelter ("**PGM Smelter**") and base metal refinery ("**BMR**") to be located in Saudi Arabia. Earlier in December 2023, Ajlan and the Company entered into a Cooperation Agreement to study the establishment of a stand-alone PGM Smelter and BMR in Saudi Arabia. According to the terms of the MOU, MISA will offer strategic guidance and study potential financial support to the proposed PGM Smelter and BMR and the Waterberg Project located in South Africa.

**On November 13, 2024**, the Company filed a final short form base shelf prospectus (the "**Shelf Prospectus**") with the securities regulatory authorities in each of the provinces and territories of Canada and a corresponding registration statement on Form F-10 (the "**Registration Statement**") with the U.S. Securities and Exchange Commission ("**SEC**"), under the Multijurisdictional Disclosure System established between Canada and the United States. Pursuant to the Shelf Prospectus and the Registration Statement, the Company may offer and sell Common Shares, debt securities, warrants, subscription receipts, or a combination thereof up to an aggregate initial offering amount of $250 million (or its equivalent in Canadian dollars) from time to time, separately or together, in amounts, at prices and on terms to be determined based on market conditions at the time of the offering and as set out in an accompanying prospectus supplement, during the 25-month period that the Shelf Prospectus and the Registration Statement remain effective.

**On September 16, 2024**, the Company reported positive results from an Independent Definitive Feasibility Study Update (the "**Waterberg DFS Update**") for the Waterberg Project. The associated technical report entitled "Waterberg Definitive Feasibility Study Update, Bushveld Igneous Complex, Republic of South Africa", with an effective date of August 31, 2024, was filed on SEDAR+ on October 9, 2024. The Waterberg DFS Update was prepared by independent qualified persons in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects ("**NI 43-101**") and Subpart 229.1300 and Item 601(b)(96) of the SEC's Regulation S-K (collectively, "**S-K 1300**"). The Waterberg DFS Update included revised mineral resource and mineral reserve estimates. For details of the Waterberg DFS Update see the Company's news release dated September 16, 2024, the MD&A, and the technical report referred to above.

**On April 3, 2024**, the directors and shareholders of Waterberg JV Co. unanimously approved a $1.35 million budget to allow the continuation of work programs underway while finalizing the Waterberg DFS Update. This budget, covering the period from March 2024 to approximately August 2024, was a subcomponent of the Pre-Construction Program.

**Results For the Year Ended August 31, 2025**

During the fiscal year August 31, 2025, the Company incurred a net loss of $4.54 million (August 31, 2024 - net loss of $4.61 million). General and administrative expenses during the period were $3.66 million (August 31, 2024 - $3.42 million). Share based compensation was $1.19 million (August 31, 2024 - $1.36 million). The foreign exchange gain recognized in the current period was $95 thousand (August 31, 2024 - $4 thousand) due primarily to the U.S. Dollar increasing in value relative to the Canadian Dollar during the year.

At August 31, 2025, finance income consisting of interest earned in the twelve-month period amounted to $0.28 million (August 31, 2024 - $0.44 million). Basic and diluted loss per share for the year ended August 31, 2025, was $0.04 (August 31, 2024 - $0.05).

Accounts receivable at August 31, 2025, totalled $77 thousand (August 31, 2024 - $0.23 million) while accounts payable and other liabilities amounted to $0.78 million (August 31, 2024 - $0.90 million). Accounts receivable was comprised primarily of value added taxes repayable to the Company in South Africa. Accounts payable consisted primarily of accruals and payables related to accounting costs, legal costs and project engineering and maintenance costs on the Waterberg Project.

Total expenditures on the Waterberg Project, before partner reimbursements, for the year ended August 31, 2025, were approximately $2.0 million (August 31, 2024 - $3.0 million). At period end, $49.2 million (August 31, 2024 - $47.0 million) in accumulated net costs were capitalized to the Waterberg Project. Total expenditures on the property since inception to August 31, 2025, are approximately $91.1 million.

For more information on mineral properties, see Note 4 of the Financial Statements.

**Outlook**

The Company's primary business objective is to advance the Waterberg Project to a development and construction decision. PTM is the operator of the Waterberg Project as directed by a technical committee comprised of itself and representatives from joint venture partners Implats, Mnombo, and HJM.

On October 18, 2022, Waterberg JV Co. approved in principle the Pre-Construction Program, including proposed work on initial road access, water supply, essential site facilities, a first phase accommodation lodge, a site construction power supply from state utility Eskom and advancement of the Waterberg Social & Labour Plan. Work to prepare the Waterberg DFS Update, including drilling and updated mineral resource and mineral reserve estimates, was a component of the Pre-Construction Program and has been completed. Approximately one half of the Pre-Construction Program has been completed. Remaining components are being undertaken in phases as incremental budgets are approved.

Before a construction decision can be undertaken, arrangements will be required for Waterberg Project concentrate offtake or processing. The Company and Waterberg JV Co. are assessing commercial alternatives for mine development financing and concentrate offtake. As a part of the Company's investigation of smelting and base metal refining options, the Company has engaged in discussions with all South African integrated producers, including Implats, with a view to negotiating formal concentrate offtake arrangements for the Waterberg Project. To date no terms have been agreed. As an alternative the Company is also studying the possible establishment of smelter and base metal refinery facilities located in either Saudi Arabia or South Africa. Before any processing of materials in Saudi Arabia could occur, South African Government authorization for the export of concentrate or matte would be required.

The Company continues to work closely with regional and local communities and their leadership on mine development plans to achieve optimal outcomes and best value to all stakeholders.

The Company is also advancing an initiative through Lion Battery Technologies Inc. ("**Lion**") using platinum and palladium in lithium battery technologies in collaboration with an affiliate of Valterra Platinum Limited (previously Anglo American Platinum Limited) ("**Valterra**") and Florida International University ("**FIU**"). As the world seeks to decarbonize and look for solutions to climate change, the adoption of battery electric vehicles is forecast to reduce the future demand for PGMs used in autocatalysis. The unique properties of PGMs as powerful catalysts are being applied to various technologies as possible solutions for more efficient energy generation and storage, which may create new demand for PGMs. The Company's battery technology initiative through Lion with partner Valterra represents one such new opportunity in the high-profile lithium battery research and innovation field. The investment in Lion creates a potential vertical integration with a broader industrial market development strategy to bring new technologies to market which use palladium and platinum. For more detail, please see the Company's MD&A and AIF.
