Ideal Power (IPWR) Q3 2026 earnings review
Ideal Power adds partners, but cash burn rises without orders
Ideal Power is signing up more engineering partners for its two-way power switches, but customer evaluations are not turning into commercial revenue. Third-quarter sales were $7,000, while quarterly cash burn reached $2.9 million on higher staffing and research costs. Chief executive David Somo said the sales funnel reached $450 million, which means additions slowed by half to $50 million by our math.
| Revenue | $7,000 -71% from a year ago |
|---|---|
| Quarterly cash burn | $2.9M top of $2.7–2.9M outlook |
| Sales opportunity funnel | ~$450M up ~$50M from last quarter |
| Cash balance | $38.3M no long-term debt |
⚖️ Verdict: 🔴 Bearish
The story got worse because commercial milestones softened while spending hit the top of the company's plan. A planned hardware prototype for a US cloud company shifted to a modeling and simulation study, and the release gave no update on the lead Asian customer's August prototype shipment. On the positive side, the company built working chips at its new Asian factory and demonstrated a data-center breaker with Power Integrations.
The question now is whether fourth-quarter evaluations produce firm purchase orders or slip into 2027. Bulls see the distributor launch and paid engineering studies as steps toward volume production, while sceptics see an unweighted funnel that never converts. Fourth-quarter results will show if the company finishes industrial reliability testing and books its first prototype build orders.
🐂 Bull Case
Power Integrations Prototype and Distributor Stocking Broaden Reach
Ideal Power makes B-TRAN, a two-way semiconductor switch designed to replace slower mechanical switches in power grids and data centers. Chief executive David Somo said the company "demonstrated an intelligent circuit breaker prototype in collaboration with Power Integrations" during the quarter. The two companies are now building a joint reference design for 800-volt direct-current data centers so customers can test a working system.
The Austin chipmaker also started shipping its own reference design kits, which are test boards that let engineers evaluate the switch. Electronics distributor Richardson Electronics now stocks those kits and takes orders, and Ideal Power is finalizing a paid development contract with a global industrial company for a 125-amp breaker.
What to watch: commercial product orders from distributors or the Power Integrations partnership in 2027. Test kits and paid engineering projects bring small fees, so only volume component orders will prove customers prefer B-TRAN over silicon carbide switches.
Asia Foundry Produced Working Chips Ahead of Qualification
B-TRAN requires double-sided wafer processing, so proving that a high-volume factory can make the chip reliably is both a growth driver and a key technical risk. In the third quarter, Ideal Power produced its first working B-TRAN chips at its new automotive-qualified wafer factory in Asia and continued optimizing the manufacturing process.
The semiconductor developer said it is "making progress toward completion by the end of the year" on JEDEC qualification, the standard reliability test required by industrial buyers. Passing that test at a high-volume plant removes a hurdle for industrial customers, even though separate automotive reliability testing remains unscheduled.
What to watch: confirmation in the fourth-quarter report that B-TRAN passed JEDEC industrial qualification without delay. Completing the test on time would allow industrial customers to move from bench testing to commercial orders.
🐻 Bear Case
Sales Funnel Growth Slowed and Brought No New Orders
Somo said Ideal Power "expanded our sales funnel to approximately $450 million" as data centers look at 800-volt power systems. The sales funnel is management's unweighted estimate of potential revenue across all customer discussions, and bulls view its expansion as the main driver of future sales. However, the funnel added about $50 million this quarter by our math, half the $100 million pace of the prior two quarters, and commercial revenue was just $7,000.
- Third-quarter revenue: $7,000, down 71.4% from $24,450 a year ago
- Nine-month revenue: $12,800, down 66.1% from $37,728 a year ago
- Net new sales funnel: about $50 million, down from about $100 million in both the first and second quarters by our math
A key data-center milestone also shifted from hardware toward software modeling. Last quarter, the company aimed to deliver a physical circuit-breaker prototype for a US cloud giant by year-end. Now it is finalizing a contract to "jointly conduct an engineering study and modeling work that provides a simulation platform for a U.S. hyperscaler" starting in the fourth quarter.
What to watch: signed design wins and initial purchase orders in the fourth-quarter report. Because industrial design cycles take 12 to 18 months after a win, another quarter without commercial orders pushes volume revenue further into 2028.
Operating Expenses and Cash Burn Reached Multi-Year Highs
Ideal Power is spending more to hire engineers and sales staff before commercial revenue arrives. Total operating expenses rose 29.8% from a year ago to $3.92 million, lifting the quarterly net loss to $3.58 million. The company blamed "higher personnel costs, stock-based compensation expense, and non-cash patent impairment charges as we rationalized our pending patent portfolio" for the increase.
- General and administrative expense: $1.61 million, up 68.3% from a year ago
- Sales and marketing expense: $475,110, up 78.2% from a year ago
- Research and development expense: $1.83 million, up 27.8% from the second quarter
- Patent write-offs: $178,326 in the third quarter by our math, after $215,133 in the first half
Research spending missed the company's prior plan for flat-to-lower second-half costs against the $1.73 million first-half quarterly average. Cash used in operations and investing reached $2.9 million, landing at the top of the $2.7–2.9 million plan after four straight quarters at or below the bottom of the range.
What to watch: fourth-quarter cash burn against the $2.7 million implied by the prior full-year outlook. A reading above $2.8 million would break the annual spending cap and shorten the company's cash runway.
Customer Concentration and Silent Lead Asia Partner
Ideal Power's near-term commercial hopes have rested on two names: automaker Stellantis and a lead customer in Asia that signed the company's first circuit-breaker design win in late 2024. Last quarter, management planned to ship low-current breaker prototypes to that Asian partner in August and receive initial low-volume chip orders in the fourth quarter.
The third-quarter release did not mention the Asian partner or the August shipment at all, highlighting instead a new customer evaluating a 63-amp breaker for battery storage. With Stellantis, Ideal Power is still supporting evaluations of second-generation samples and working toward a fourth-quarter milestone, after original purchase-order deliverables slipped past mid-2026.
What to watch: whether the lead Asian customer places initial prototype build orders before year-end. Silence on those orders in the fourth-quarter report would indicate that the company's furthest-along industrial program has stalled.
Risks this quarter didn't answer
Three standing risks regarding market timing, competition, and financing received no update in the third-quarter press release.
- Data-center 800-volt adoption timing: commercial deployments are not expected until the second half of 2027 or later; customer design commitments in early 2027 will test the schedule.
- Competition from silicon carbide incumbents: established chipmakers like Infineon already sell solid-state breaker switches at scale; head-to-head design wins will test B-TRAN's advantage.
- Future share dilution: a three-year shelf registration remains active; quarterly filing disclosures on share issuance or strategic equity talks will show if management taps it.
💲 Other KPIs
Cash fell 7.3% from $41.29 million in the second quarter as the company funded $2.9 million of operating and investing activities. Ideal Power holds no long-term debt. At the current spending pace, the balance covers more than three years of operations without new share sales.
Share count more than doubled from 9.15 million a year ago and rose 17.3% from the second quarter. The increase reflects the full-quarter weight of May's $27.7 million stock offering and February's $12.6 million raise. Higher share count cut net loss per share to $0.18 from $0.32 a year ago even though total net loss grew.
Inventory dropped 42.7% from $62,425 at the end of June, though it stays above the $9,700 balance at year-end 2025. The sequential drop matches the initial shipment of 800-volt circuit-breaker reference design kits to distributor Richardson Electronics and evaluation customers.
🔮 Guidance
Unchanged. The company still plans to finish industrial reliability testing for B-TRAN by the end of the fourth quarter. Management did not include numeric cash burn or research spending ranges in the press release, as it typically gives financial targets on the conference call. By our math, the prior full-year cash burn plan of $10.3–10.5 million leaves $2.6–2.8 million for the fourth quarter.
❓ Key Questions
Did the lead Asian customer receive its August prototypes?
Last quarter management planned to ship low-current breaker units to its first design-win customer in August and receive initial chip orders in the fourth quarter. The release omitted the customer entirely.
Why did the cloud giant project shift to a simulation?
In August the company targeted delivery of a co-developed hardware prototype for a US cloud company by year-end. The release now describes finalizing a contract for a modeling and simulation platform.
Does the $10.3–10.5 million full-year cash burn outlook hold?
Nine-month cash burn reached $7.7 million after a $2.9 million third quarter, and research spending exceeded the first-half average. Hitting the annual target requires fourth-quarter burn to drop to $2.7 million.
Why is Ideal Power writing off capitalized patents?
The company wrote off $178,326 of capitalized patents in the third quarter by our math, bringing nine-month write-offs to $393,459. Investors need to know which pending patents were dropped and why.
