(“Alta Renewables”) to build, own, and operate a portfolio of four shovel-ready solar-plus-storage projects totaling 87.5 megawatts-peak (“MWp”) across the Philippines. The MOU anticipates that SunScout will fund construction of each plant, take on long-term ownership, and operate them across 20-year, fixed-price power supply agreements — while Alta Renewables remains involved as co-development and operations partner. The MOU is SunScout's first project cooperation since completing its listing on the NYSE American and NYSE Texas exchanges on August 13, 2026. Highlights of the project include: <ul type="disc"><li style="text-align:justify;">20-year fixed-price power supply agreements supporting contracted revenue per plant.</li><li style="text-align:justify;">≥10% target project-level internal rate of return (“IRR”).</li><li style="text-align:justify;">112.5 MWp of projected owned and operated capacity upon completion of the ILECO 3 expansion.</li><li style="text-align:justify;">230+ MWp of further Build-Own-Operate (“BOO”) pipeline under discussion. </li></ul> SunScout expects to fund the full build-out on a project-by-project basis — an estimated USD 1,000,000 per MWp, or roughly USD 87.5 million of invested capital across the initial portfolio — covering engineering, construction, and battery storage integration with SunScout retaining full ownership of every plant it builds. Once a plant reaches commercial operation, SunScout intends to implement project-level financing of approximately 70% debt, recycling the majority of its invested capital into new projects while retaining full ownership and the long-term cash flow generated by each asset. Paired with 20-year, fixed-price offtake agreements at rates of up to Php 6.00 per kWh and a target of at least 10% project-level IRR, SunScout expects the portfolio to generate durable, contracted earnings for up to two decades per plant. SunScout expects each plant to pair solar generation with an Integrated Renewable Energy Storage System (“IRESS”) and a long-term power supply agreement with a local electric cooperative. The final terms are expected to be: <ul type="disc"><li style="margin-bottom:5pt; text-align:justify;">AKELCO — 25.0 MWp with 10.0 MWac / 27.5 MWh of storage; locked in under a 20-year power supply agreement with Aklan Electric Cooperative at a fixed Php 6.00/kWh; land rights secured, ready-to-build status targeted for September 2026.</li><li style="margin-bottom:5pt; text-align:justify;">FLECO — 12.5 MWp with 10.0 MWac of storage; 20-year power supply agreement with First Laguna Electric Cooperative at a fixed Php 4.85/kWh; ready-to-build status targeted for December 2026.</li><li style="margin-bottom:5pt; text-align:justify;">ILECO 3 — 25.0 MWp with 20.0 MWac / 70 MWh of storage (with an additional approximately 25 MWp under development that would expand SunScout's owned capacity here to roughly 50 MWp); indicative 20-year offtake terms of Php 5.75+/kWh with a consortium of electric cooperatives; ready-to-build status targeted for December 2026.</li><li style="margin-bottom:5pt; text-align:justify;">ZAMECO II — 25.0 MWp with 10.0 MWac / 27.5 MWh of storage; 20-year power supply agreement with Zambales II Electric Cooperative at a fixed Php 5.79/kWh; ready-to-build status targeted for December 2026. </li></ul> Alta Renewables, which brought each project to “Ready-to-Build” status — securing land rights, cooperative offtake terms, and permitting progress — will remain closely involved as SunScout's Philippine co-development and O&amp;M partner, continuing to manage local permitting, cooperative relationships, and day-to-day plant operations under SunScout's oversight. The MOU anticipates that Alta Renewables will also have the option to co-invest alongside SunScout for up to 33% of the equity in each project, aligning both companies around the long-term performance of the assets. SunScout anticipates compensating Alta Renewables for its development work on a milestone basis — 80% as each project reaches Ready-to-Build status and 20% upon regulatory approval of its power supply agreement, calculated at USD 100,000 per MWp. “This is a BOO model at its best,” said Mr. Edwin Cywinski, Chairman and Chief Executive Officer of SunScout. “Alta Renewables gets these projects to shovel-ready, and we bring the capital to build them — then we own and operate them for the next 20 years under contracted, fixed-price agreements. That's exactly the kind of durable, growing earnings stream we want on our balance sheet, and with more than 230 additional megawatts already in Alta's pipeline, this will be a partnership we expect to keep growing for years to come.” “We plan for this to be more than a single transaction,” said Mr. John Michael Bernil of Alta Renewables. “Per the MOU SunScout would fund construction, take on long-term ownership, and keep us involved as an operating partner and equity co-investor. That would give our cooperative partners confidence these plants will be built and run well for the next two decades and gives us a platform to keep developing new projects together.” Beyond the initial 87.5 MWp, SunScout and Alta Renewables intend to negotiate an overarching framework agreement naming Alta Renewables as SunScout's preferred BOO partner for future Philippine solar and storage projects. Alta Renewables' current pipeline includes the additional approximately 25 MWp under development at ILECO 3, a 25 MWp project with CAPELCO, and a 99 MWp project with CAGELCO II — together representing more than 230 MWp of further Build-Own-Operate opportunity for SunScout in the Philippines alone, on top of the initial portfolio. The parties are targeting execution of definitive project agreements on or about August 24, 2026, followed by formal adoption by SunScout's board of directors, mobilization of project financing, and financial close on the first project in the fourth quarter of 2026. The cooperation remains subject to satisfactory due diligence, internal and board approvals, and negotiation and execution of definitive agreements. There can be no assurance that the parties will complete the transactions described, on these terms or at all.
