AUSTIN, Texas, Nov. 12, 2026 /PRNewswire/ — Ideal Power Inc. (Nasdaq: IPWR) (“Ideal Power,” the “Company,” “we,” “us” or “our”), developer and provider of its innovative and widely patented B-TRAN® bidirectional semiconductor power switch, reports results for its third quarter ended September 30, 2026.

“Customer engagements expanded as the transition to higher-voltage DC architectures is accelerating demand for solid-state circuit protection,” said David Somo, President and Chief Executive Officer of Ideal Power. “Since the start of the third quarter, we demonstrated an intelligent circuit breaker prototype in collaboration with Power Integrations, commenced shipment of our new B-TRAN® reference design kits (“RDKs”), advanced our initiative with an industry partner for a funded joint engineering study and modeling project to provide a simulation platform for a U.S. hyperscaler, continued advancing our EV opportunity with Stellantis, and progressed new customer engagements across AI data centers and energy infrastructure.”

Somo continued, “Reflecting on my first year as CEO, we are materially better positioned to advance customer opportunities through the sales funnel and into production orders. We have assembled an experienced semiconductor leadership and engineering team, expanded our sales funnel to approximately $450 million, released new RDKs, signed a long-term supply agreement with a high-volume, automotive-qualified power semiconductor foundry, and strengthened our balance sheet. Our focus remains on converting opportunities across our expanding sales funnel into volume production orders, revenue growth and long-term shareholder value.”

Key Third Quarter 2026 and Recent Business Highlights

Execution of our B-TRAN® commercial strategy continues, including:

• Announced a collaboration with Power Integrations to develop a self-powered, intelligent, ultra-fast solid-state circuit breaker (“SSCB”) for 800-volt DC data centers. With a working prototype already demonstrated, the collaboration is now progressing to a joint reference design for potential customers that aims to accelerate commercialization across the data center market.
• Finalizing a statement of work with a global industrial technology company for an NRE funded 800-volt DC 125-amp SSCB development project that is planned to begin this quarter. The company serves a broad range of markets, including data centers, other industrial applications, and automotive.
• Initiated a new engagement with a large potential customer. They are currently evaluating B-TRAN® in an 800-volt DC 63-amp SSCB for integration in battery energy storage systems. This SSCB can also be used for data center applications. With a successful evaluation, this customer intends to demonstrate and promote the solution during its end-of-year customer exhibition.
• Finalizing a statement of work for an NRE funded project with an industry partner, with whom we signed an LOI earlier this year, to jointly conduct an engineering study and modeling work that provides a simulation platform for a U.S. hyperscaler. This project is expected to be confirmed and begin in the fourth quarter.
• Expanded distribution of our 800-volt SSCB RDK to accelerate product evaluations and potential adoption. Richardson Electronics now stocks the RDK and has begun accepting customer orders, with additional stocking orders from other distributors, as well as direct orders, expected in the coming months.
• Continued advancing our solid-state EV contactor opportunity with Stellantis by supporting its evaluation of Gen 2 B-TRAN® custom-packaged samples and development kits and continuing work on system-level specifications. Deliverables completed to date support the next project milestone scheduled for this quarter. We also continue to expand our broader automotive pipeline with additional global automakers and Tier 1 suppliers.
• Advanced manufacturing readiness with continued process flow optimization at our high-volume, automotive-qualified semiconductor wafer foundry in Asia, where we achieved functional B-TRAN® first silicon. The foundry has ample capacity to support high-volume industrial and automotive customers at a cost structure we believe supports targeted gross margins at scale. For JEDEC qualification, we are making progress toward completion by the end of the year.
• Started to realize the strategic benefits of our newly formed Advisory Board, with its first member, Dr. Sanjai Parthasarathi, contributing to our multi-year strategic planning and facilitating introductions to leading companies in data centers, AI infrastructure, and related technology markets.
• B-TRAN® Patent Estate: Currently at 108 issued B-TRAN® patents with 52 of those issued outside of the United States. Current geographic coverage includes North America, China, Taiwan, Japan, South Korea, India, and Europe.

Third Quarter 2026 Financial Results

• Cash and cash equivalents totaled $38.3 million at September 30, 2026.
• Cash used in operating and investing activities in the third quarter of 2026 was $2.9 million compared to $2.7 million in the third quarter of 2025.
• Cash used in operating and investing activities in the first nine months of 2026 was $7.7 million compared to $7.4 million in the first nine months of 2025.
• No long-term debt was outstanding at September 30, 2026.
• Operating expenses in the third quarter of 2026 were $3.9 million compared to $3.0 million in the third quarter of 2025 driven primarily by higher personnel costs, stock-based compensation expense, and non-cash patent impairment charges as we rationalized our pending patent portfolio.
• Net loss in the third quarter of 2026 was $3.6 million compared to $2.9 million in the third quarter of 2025. Net loss in the first nine months of 2026 was $10.6 million compared to $8.7 million in the first nine months of 2025.
