Legend Power Announces Preliminary Findings from Independent Evaluation of SmartGATE Operating Performance

About this update from Legend Power Systems Inc.

Interim Results Demonstrate Improved Operating Voltage Conditions, Reduced Modeled Thermal Stress, and Measured Energy and Demand Benefits Vancouver, British Columbia--(Newsfile Corp. - June 16, 2026) - Legend Power Systems Inc. (TSXV: LPS) (OTCQB: LPSIF) ("Legend Power" or the "Company"), a global leader in commercial electrical system solutions, today announced preliminary findings from an ongoing independent government-funded evaluation of SmartGATE™ operating performance at a federal facility. The evaluation is assessing the impact of SmartGATE on building operating conditions, energy consumption, demand characteristics, and infrastructure-related performance metrics under normal operating conditions. A final report is expected in October 2026. According to the interim findings, the facility was regularly operating approximately 32 to 35 volts above optimized equipment nameplate voltage conditions during normal utility operation. With SmartGATE engaged, operating voltage was maintained within approximately 1 to 2 volts of equipment nameplate. Using standard electrical loss modeling, the elevated voltage conditions observed during baseline operation translated into approximately 14% to 16% higher thermal stress on building systems, equivalent to roughly a 7-degree Celsius increase in operating severity. The interim measurement and verification analysis also demonstrated approximately 2.6% energy savings, average demand reductions in the 2% to 4% range, and peak demand reductions approaching 25% during portions of the evaluation period. The interim findings are preliminary in nature and remain subject to review, refinement, and inclusion in the final report. Final conclusions may differ from the preliminary findings reported herein. In addition to the measured evaluation results, facility operations personnel reported several operational improvements following SmartGATE deployment. According to feedback provided by facility staff, these observations included reduced lighting flicker, fewer breaker trips, fewer variable frequency drive ("VFD") resets, and reductions in HVAC and elevator reset activity. These observations were provided by facility personnel and are not part of the formal measurement and verification results. The Company has not independently quantified these observations, and they are not included within the ...
