Greenlight Metals Inc. Announces Warrant Extensions and Equity Incentive Plan Grants

- All new incentive grants to Insiders priced or valued at $0.30 per share -

Medford, Wisconsin--(Newsfile Corp. - May 14, 2025) - GreenLight Metals Inc. (TSXV: GRL) ("GreenLight" or the "Company") announces that the Company proposes to extend the expiry date of an aggregate of 1,249,072 outstanding share purchase warrants (the "Warrants"). Each Warrant entitles the holder thereof to acquire one common share of the Company (a "Share") at a price of $0.60 per Share. The Company proposes to extend the expiry date of the Warrants by an additional two years (the "Amendment"). All other terms of the warrants, including exercise price, will remain the same. The Warrants were issued pursuant to the following private placements and were extended as follows:

• 461,293 Warrants, including 75,000 Warrants issued to insiders, were issued pursuant to a private placement which closed on June 7, 2022. These Warrants were set to expire on June 7, 2025, and the expiry date was extended to June 7, 2027.

• 425,000 Warrants were issued pursuant to a private placement which closed on July 8, 2022. These Warrants were set to expire on July 8, 2025, and the expiry date was extended to July 8, 2027.

• 362,779 Warrants, including 264,611 Warrants issued to insiders, were issued pursuant to a private placement which closed on January 24, 2023. These Warrants were set to expire on January 24, 2026, and the expiry date was extended to January 24, 2028.

The Amendment is subject to acceptance by the TSX Venture Exchange ("TSXV"), and no action will be required on the part of the holders of the Warrants to give effect to the Amendment.

A total of 339,611 Warrants are held by parties who are considered to be "related parties" of the Company. Therefore, the amendment of these warrants constitutes a "related party transaction" as contemplated by Multilateral Instrument 61-101 Protection of Minority Shareholders in Special Transactions, and TSXV Policy 5.9 - Protection of Minority Shareholders in Special Transactions. However, the exemptions from formal valuation and minority approval requirements provided for by these guidelines can be relied upon as the fair market value of the warrants held by insiders does not exceed 25% of the market capitalization of the Company. A material change report in respect of the warrant extension will be filed by the Company.

The Warrants and the underlying Shares have not been and will not be registered under the United States Securities Act of 1933, as amended (the "U.S. Securities Act"), or any state securities laws and may not be offered or sold within the United States or to, or for the account or benefit of, a U.S. person (as defined in Regulation S under the U.S. Securities Act) unless registered under the U.S. Securities Act and applicable state securities laws, or an exemption from such registration is available. This press release does not constitute an offer to sell or a solicitation of an offer to buy any of the securities referred to herein.

Incentive Grants

As part of the Company's incentive program, the Company made grants of incentive stock options ("Options"), restricted share units ("RSUs") and deferred share units ("DSUs") in accordance with the Company's amended and restated equity incentive plan (the "Equity Incentive Plan"), the effectiveness of which is subject to shareholder approval at the next meeting of shareholders and final acceptance by the TSXV.

On the recommendation of the Nomination, Compensation and Corporate Governance Committee, the board of directors of the Company has approved the grant of an aggregate of 668,333 RSUs, 293,750 DSUs and 1,575,000 Options.

The Equity Incentive Plan's objective is to create an incentive compensation program that is aligned with the Company's long-term objectives. Options, DSUs and RSUs are granted in accordance with Policy 4.4 - Security Based Compensation of the TSXV, the terms and conditions of the Equity Incentive Plan and the terms of the award agreement evidencing such equity compensation security. Values for RSU and DSU awards were determined using a notional share price of $0.30.

RSUs: Each vested RSU can be redeemed for one fully paid and non-assessable common share of GreenLight issued from treasury.
