GREENBRIAR ANNOUNCES PREB ORDER

After the market hours of Friday, June 12, 2026, the Puerto Rico Energy Bureau (the government energy regulator) has ordered PREPA and Greenbriar Sustainable Living Inc. to complete negotiations within the next seven days from this date. If the parties reach agreement within such period, they shall jointly notify the energy bureau and submit the corresponding proposed contract or contracts for the energy bureau's review and determination within the same seven-day period. The energy bureau warns PREPA that, under Article 6.36 of Act 57-2014k, non-compliance with this resolution and order may carry the imposition of fines.

The negotiations are in specific reference to a 40-megawatt four-hour and six-hour battery storage system with Greenbriar pricing at $24,000 and $33,000 per megawatt per month in fees, respectively. This is separate and in addition to its 80-megawatt alternative current solar contract settlement pricing of 11.3 per kilowatt-hour, weighted average.
