Big Six Towers

9/22/2025 Brief Power Outage

Dear Shareholders,

At approximately 6:55PM yesterday, the entire Big Six Towers complex experienced a brief power outage.

Our power plant team conducted an immediate investigation and determined that the incident was likely caused by a mechanical overspeed on the RPM sensor for natural gas engine #1. When engine #1 dropped its load, the remaining engines were unable to fully support the demand, resulting in the temporary outage.

The team is continuing a thorough review to confirm the cause and ensure that no other issues contributed to the event.

We appreciate your patience and understanding.

Thank you,

Big Six Towers

Management
