Units to Be Deployed Through Leading National Rental Partner to Three of North America’s Largest General Contractors

Toronto, Ontario – December 10, 2025 – TheNewswire - Hybrid Power Solutions Inc. (CSE: HPSS) (OTC: HPSIF) (FSE: E092) ("Hybrid" or the "Company") is excited to announce that production has officially commenced on eleven (11) Spark portable industrial battery systems. These units are being manufactured for immediate deployment through one of North America’s leading national equipment rental companies and will be placed with three of the continent’s largest general contractors. These units are part of the first delivery of the previously announced LMDH order.

The Spark units, known for their zero-emission, silent operation and rapid deployment capabilities, will support high-impact construction projects across Canada, replacing traditional diesel generators on job sites ranging from urban infrastructure development to large-scale commercial and civil projects.

“This order marks a significant milestone in the commercial rollout of our Spark platform,” said Francois Byrne, CEO of Hybrid Power Solutions. “Having three of the biggest and most respected general contractors in North America adopt Hybrid’s battery technology through a trusted national rental partner validates both the performance of the Spark and the growing demand for cleaner, more efficient power solutions on job sites. This deployment further demonstrates the shift away from diesel toward portable battery and diesel-hybrid systems that deliver lower operating costs, zero or lower emissions, and full compliance with increasingly stringent environmental and noise regulations.”

Key benefits being realized by the end users include:

• Reduction of diesel fuel consumption and associated refueling logistics  

• Silent operation, enabling extended and night-time work in noise-sensitive areas  

• Instant power delivery with no warm-up time  

• Remote monitoring and fleet management capabilities  

• Significant reduction in carbon emissions and on-site pollutants  

Production of the eleven (11) Spark units has commenced, with delivery for Q1 2026. Our rental partner is indicating strong interest in expanding the fleet throughout 2026 based on field performance and contractor feedback.
