Ideal Power Reports First Quarter 2025 Financial Results

AUSTIN, TX – May 15, 2025 -- Ideal Power Inc. (Nasdaq: IPWR) (“Ideal Power,” the “Company,” “we,” “us” or “our”), developer and innovative provider of the highly efficient and broadly patented B-TRAN® bidirectional semiconductor power switch, reports results for its first quarter ended March 31, 2025.

“We had a strong start to the year as we completed SSCB prototypes related to our first design win three months ahead of schedule. We expect industrial markets, particularly the SSCB market, to be the earliest source of our initial sales ramp starting in the second half of this year. In addition, based on positive feedback from Stellantis, we expect to not only continue advancing the drivetrain inverter program but also add a new high priority program for EV contactors,” stated Dan Brdar, President and Chief Executive Officer of Ideal Power. “I am excited to announce today that we secured an order from a third Forbes Global 500 power management market leader interested in B-TRAN® for circuit protection for power distribution systems with a focus on DC microgrids for solar and wind.”

Brdar continued, “We expect minimal impact from recently enacted tariffs, although the situation remains dynamic with rapidly changing tariffs and trade policies. Power semiconductors are exempt from most tariffs currently in effect, including those applicable to the countries where we fabricate B-TRAN® wafers.”

Key First Quarter and Recent Operational Highlights

Execution to our B-TRAN® commercial roadmap continues, including:

●

Completed solid-state circuit breaker (SSCB) prototypes related to our first design win three months ahead of schedule. The customer completed their initial prototype testing and we continue to collaborate with this customer on their first B-TRAN®-enabled SSCB product.
