Homerun Resources Inc. Announces Sponsored BDR Listing on B3 Stock Exchange

Expanding Access to Brazilian Investors and International Investors Focused on the Energy Transition in Brazil

Homerun Resources Inc. (TSXV: HMR,OTC:HMRFF) (OTCQB: HMRFF) ("Homerun" or the "Company") is pleased to announce that the Company has entered into a Sponsored Brazilian Depositary Receipt ("BDR") program with Banco B3 S.A. (the "Depositary"), pursuant to a Sponsored BDR Service Agreement dated March 27th, 2026. The program provides for the listing and trading of Homerun BDRs on B3 S.A. Brasil, Bolsa, Balcão ("B3"), Brazil's main stock exchange, under a ticker to be announced following final admission by B3 and registration by the Comissão de Valores Mobiliários ("CVM").

The Sponsored BDR program will initially be a Level I – confirm program, with each BDR representing one common share of Homerun, which continues to trade on the TSX Venture Exchange (the "TSXV") under the symbol HMR (the "Underlying Share"). The Underlying Shares corresponding to the BDRs will be held in custody outside Brazil in an account designated for the program, and new BDRs will only be issued when the Depositary acquires and blocks the corresponding Underlying Shares. As a result, when Brazilian investors purchase Homerun BDRs on B3, the Depositary will source the Underlying Shares from the TSXV market (or from existing blocked inventory), effectively drawing on the Company's TSXV-listed float and reducing the freely tradable supply in Canada as BDRs are created and outstanding.

The Company is pursuing the B3 listing in response to growing inbound interest from Brazilian institutional investors and family offices, particularly in advance of Homerun's planned bankable feasibility study ("BFS") and project financing which has received indicative support from BNDES, Brazil's national development bank (see news release).

Management believes that providing a locally traded, real-denominated security will materially lower operational and regulatory frictions for Brazil-based investors who wish to participate in Homerun's growth, including those that have mandates or internal guidelines requiring investment through Brazilian listed instruments. The listing will also facilitate international investment in the ongoing Energy Transition that is taking place in Brazil as Homerun is a leading vertically integrated company in that Federal Government mandate.

By listing on B3 via a Sponsored BDR program, Homerun expects to: (i) broaden and diversify its shareholder base in Brazil; (ii) enhance visibility among Brazilian institutions, family offices and high-net-worth investors; (iii) provide an investment opportunity in the Energy Transition occurring in Brazil; and (iv) create an additional trading venue that may support liquidity and valuation for the Company's shares over time. The BDR structure is designed to maintain economic and voting equivalence between the BDRs and the Underlying Shares, with price discovery linked through arbitrage between B3 and the TSXV.

Further details regarding the BDR program – including level, ticker symbol, commencement of trading and any investor eligibility limitations under CVM regulations – will be announced upon receipt of the necessary approvals from B3 and the CVM.

About Brazilian Depositary Receipts (BDRs)
Brazilian Depositary Receipts are certificates issued in Brazil that represent securities of a foreign issuer, enabling those securities to trade on B3 in Brazilian reais while being backed by shares held in custody abroad. Sponsored BDR programs are created with the participation of the foreign issuer and a Brazilian depositary bank, and can be structured at different levels with corresponding disclosure and offering regimes.
