BFS HIGHLIGHTS

• Base-case NPV of approximately US$670 million (and US$829 at 105% production)
• IRR of 20.2% at 100% production (and 23.1% at 105% production) significantly exceeding the Project's estimated WACC of 4.6%, indicating substantial value creation above the cost of funding
• After startup in 2028, indicative gross margin of approximately 50% at projected 2030 domestic pricing
• After startup in 2028, estimated specific operating costs of approximately US$520.2 per tonne by 2030 and US$581.2 per tonne in 2033, compared to projected domestic selling prices of approximately US$1,033 per tonne and US$1,196 per tonne, respectively
• Plant designed to reach full run-rate solar glass production of approximately 288,300 tonnes per annum from Year 5 of operations (SORG furnaces are designed to operate at up to 10% above their nominal capacity)
• Estimated payback period of approximately 7.6 years
• Estimated total initial CAPEX of approximately US$396.5 million, net of VAT and other local taxes
• Estimated annual revenue of US$ 294.3 million and OPEX of approximately US$143.3 million in 2030, and approximately US$ 344.9 / US$167.6 million in 2033 after ramp-up
• The glass furnace is designed for a 15-year operating campaign, with depreciation modeled conservatively over 20 years
• Project start contemplated in November 2026 subject to financing and advancement of detailed engineering and approvals
• Strategic location in Belmonte, Bahia, neighbouring Homerun's commanded low-iron silica sand mine and offering room for a potential second production line which market projections indicate as very likely to be required in the medium term
• The BFS projects 474 direct employees - 7 managers and 467 engineers and technical staff
• The plant design incorporates an on-site photovoltaic power system, reducing grid dependency and supporting the Company's lower-carbon production mandate
• No current solar pattern glass manufacturer identified in the Americas in the BFS, supporting a potential first-mover advantage for Homerun
• Project site video available here: VIDEO

Vancouver, May 12, 2026 - Homerun Resources Inc. (TSXV: HMR) (OTCQB: HMRFF) ("Homerun" or the "Company"), a vertically integrated materials company advancing the Company's high-purity silica resources located in Belmonte, Bahia, Brazil, is pleased to announce the results of its Bankable Feasibility Study (the "BFS") for the Company's Solar Glass Manufacturing Plant to be located in Belmonte, Bahia, Brazil, adjacent to Homerun's low-iron silica sand resources.

The BFS positively confirms that the Solar Glass Manufacturing Plant is technically and economically feasible and outlines a large-scale, antimony-free solar glass manufacturing operation designed to supply both Brazil's fast-growing solar sector and selected export markets. Under the base-case assumptions set out in the BFS, the Project generates an estimated net present value ("NPV") of approximately US$670 million at 100% production and US$829 million at 105% production, an internal rate of return ("IRR") of 20.2% at 100% production and 23.1% at 105% production, and an estimated payback period of approximately 7.6 years.

The proposed plant is designed as a 1,000 tonne-per-day soda-lime patterned solar glass facility, with four 250 tonne-per-day roll glass lines, producing ultra-clear patterned glass for mono and bifacial photovoltaic modules. The BFS indicates gross glass melting capacity of approximately 365,000 tonnes per annum and solar glass production capacity ramping from approximately 239,000 tonnes per annum in the first operating year to approximately 288,300 tonnes per annum from the fifth operating year onward.

PRODUCTION VOLUME SENSITIVITY

The facility is purposely engineered with up to 10% overcapacity, with the glass melter designed to operate at up to 1,100 tonnes per day, providing probable upside to the base-case production and return assumptions based on documented historical performance.

STRATEGIC RATIONALE
The BFS highlights a strong market backdrop for the Project. The global photovoltaic market is projected to grow from approximately US$979.9 billion in 2025 to approximately US$2.25 trillion by 2036, while the global solar glass market is projected to grow from approximately US$19.93 billion in 2025 to approximately US$104.76 billion by 2036.

Brazil is identified in the BFS as the leading solar market in Latin America, yet still highly dependent on imported PV modules and solar glass. The BFS further notes that Brazil imported approximately 17.9 GW of PV modules in 2025, with approximately 79% linked to distributed generation, underscoring strong rooftop and decentralized demand.

According to the BFS, existing letters of intent indicate potential demand of approximately 380,000 tonnes per year, with additional advanced discussions indicating demand of 480,000 tonnes per year, with a realistic secured local volume based on current LOI's of approximately 160,000 to 180,000 tonnes per year after adjustment. The BFS recommends positioning Homerun's anticipated production as a premium, reliable and sustainable alternative to imported product, supported by local service, reduced logistics risk, lower-carbon production and antimony-free product positioning.

The current non-binding letters of intent reference an initial solar glass price of approximately US$750 per tonne; however, these indications are subject to negotiation of definitive binding offtake agreements, and pricing is expected to be adjusted over time to reflect inflation, market conditions and product specification. The BFS financial model assumes both selling prices and operating costs escalate at 5% per year from 2025 levels, consistent with an assumed inflationary environment over the life of the Project and does not assume margin expansion from price increases beyond inflation; margin improvements are primarily driven by operational efficiency and ramp-up to nameplate capacity.

"Completion of this Bankable Feasibility Study marks a transformational milestone for Homerun and provides a clear technical and financial blueprint for the development of what is intended to be Brazil's first solar glass manufacturing operation," said Brian Leeners, CEO of Homerun Resources. "With a projected US$670 million NPV, a 20.2% base-case IRR, access to low-iron silica sand feedstock adjacent to the proposed plant site, and exposure to a rapidly expanding Brazilian solar market, the Company believes the Project has the potential to become a strategically important regional supplier of premium solar glass in the Americas."

DEVELOPMENT PATH AND NEXT STEPS
The BFS concludes that the Homerun Solar Glass Manufacturing Plant is feasible and recommends immediate continuation of project financing arrangements, detailed engineering, tax and duties analysis, cost optimization initiatives, and offtake discussions in order to stay aligned with the contemplated development schedule. The BFS also contemplates continued work on alternative local sourcing, infrastructure cost reduction opportunities, and preparation of supply contracts for key technology packages.
