HOMERUN RESOURCES INC. FORMALLY INCLUDED IN "PROGRAMA DESENVOLVE" TAX INCENTIVE PROGRAM TO SUPPORT INDUSTRIAL DEVELOPMENT AND ECONOMIC INTEGRATION IN THE STATE OF BAHIA, BRAZIL

Homerun Resources Inc.'s wholly owned Brazilian subsidiary, Homerun Brasil Mineracao Ltda., has been formally included in programa desenvolve, the industrial development and economic integration incentive program administered by the government of the State of Bahia, Brazil.

The inclusion in programa desenvolve grants Homerun the ability to defer payment of ICMS (state value-added tax) on the acquisition of capital goods for 24 months and to defer payment of the ICMS balance on its sales for 72 months. This deferral framework is expected to significantly support working capital optimization for Homerun's flagship solar glass project in Santa Maria Eterna and improve cash flow management as the project advances through construction and into commercial operations.

The initial benefit term runs from July 1, 2026, through Dec. 31, 2032, and is granted as a counterpart to the investment commitments Homerun is making in Bahia. Homerun's solar glass project has an initial capital expenditure estimate of approximately $396.5-million (U.S.), as disclosed in the company's recently released bankable feasibility study. The BFS confirms a positive economic profile for the project and positions Homerun as a first mover in dedicated high-efficiency solar glass manufacturing in the Americas (see press release dated May 12, 2026).

Based on current ICMS limits and preliminary internal modelling, the company estimates that the combined ICMS deferrals on eligible capital goods and sales over the incentive period could translate into a non-dilutive cash flow timing benefit in the tens of millions of U.S. dollars. While the precise value will depend on actual capex deployment, ramp-up profile, realized sales volumes and prevailing ICMS rates over time, management believes that the deferrals materially enhance the project's financial flexibility during construction and early operations. These potential savings are incremental to the strong underlying economics already demonstrated by the BFS.

Brian Leeners, chief executive officer of Homerun, stated: "The inclusion of Homerun in programa desenvolve is a key validation of our long-term partnership with the State of Bahia and the strategic importance of our solar glass project to the region. By deferring ICMS on both capital goods and sales, Bahia is effectively aligning public sector support with our investment timeline, smoothing our cash flow profile during construction and ramp-up. We view this incentive as a meaningful, non-dilutive enhancement to the already compelling economics outlined in our bankable feasibility study and as another important milestone in building a vertically integrated, silica-powered platform for the energy and technology transitions in the Americas."
