Good morning, ladies and gentlemen, and welcome to the Ideal Power Second Quarter 2025 Results Conference Call. [Operator Instructions] As a reminder, this event is being recorded. I would now like to turn the conference over to Jeff Christensen. Please go ahead.

Thank you, Kelly. And good morning, everyone. Thank you for joining the Ideal Power's Second Quarter 2025 Results Conference Call. With me on the call are Dan Brdar, President and Chief Executive Officer; and Tim Burns, Chief Financial Officer. Ideal Power's second quarter 2025 financial results press release is available on the company's website at idealpower.com. Before we begin, I'd like to remind everyone that statements made on the call and webcast, including those regarding future financial results and company prospects, are forward-looking and may be subject to a number of risks and uncertainties that could cause actual results to differ materially from those described in the call. Please refer to the company's SEC filings for a list of associated risks. We would also refer you to the company's website for more supporting company information. Now I'd like to turn the call over to Ideal Power's President and CEO, Dan Brdar. Dan?

Thank you, Jeff. I appreciate everyone joining us today. I'm eager to share an update on our progress since the start of the second quarter. I'll begin with the key highlights since the beginning of the second quarter and discuss the most significant developments with additional context to highlight their significance. Afterwards, I'll turn things over to Tim to discuss our financial results. We look forward to your questions after our prepared remarks. First, we shipped updated solid-state circuit breaker prototypes to our first design win customer. These updated prototypes incorporate additional capabilities into the device driver that were requested by the customer to further differentiate their product offering. The customer is completing their prototype testing, and we'll soon begin gathering feedback on this new product from their targeted end customers ahead of the product launch of their first B-TRAN-enabled solid-state circuit breaker product planned for later this year. Second, we entered into a collaboration with a fourth global Tier 1 automotive supplier. We shipped them packaged devices, a reference design, and driver to enable them to evaluate B-TRAN, and our understanding is that they plan to launch a formal solid-state EV contactor program within the next few months. Third, one of our distributors introduced our products to a fourth global automaker and the automakers' preferred Tier 1 supplier. They ordered numerous packaged B-TRAN devices, SymCool power modules, solid- state circuit breaker reference design boards, and drivers. The customer will evaluate B-TRAN as part of their innovative solid-state EV contactor design implementation. The same distributor also introduced our products to a fifth automotive OEM for a potential EV contactor program. We're now collaborating with a total of 5 automakers, including 4 of the top 10 global automakers. Fourth, Stellantis formally informed us that they are issuing a purchase order to…

Thank you, Dan, and good morning, everyone. Our second quarter 2025 cash burn from operating and investing activities was $2.5 million, up from $2.2 million in the second quarter of 2024 and up from $2.1 million in the first quarter of 2024. Our Q2 cash burn was at the lower end of our guidance of $2.5 million to $2.7 million. Our cash burn from operating and investing activities for the first half of 2025 was $4.6 million, up from $4.2 million in the first half of 2024. We continue to manage expenses prudently and aggressively. We expect third quarter 2025 cash burn to increase to approximately $2.7 million to $2.9 million, with a full year 2025 cash burn just over $10 million, with the increase primarily due to the hiring of additional sales and engineering personnel. This compares to a 2024 cash burn of $9.2 million, excluding the benefit of warrant proceeds. Cash and cash equivalents totaled $11.1 million at June 30, 2025. We have no debt and a clean capital structure. We recorded modest revenue for the second quarter of 2025 as customers continue to evaluate our technology. While initial orders from large companies evaluating our products for potential inclusion in their OEM products will be small, we expect order sizes to increase as customers start to prototype their OEM products and progress through their design cycles and roll out B-TRAN-based products. Looking at the balance of 2025, we expect to see the start of our sales ramp with revenue from product development activities, the launch of the first B-TRAN-enabled breaker by our first design win customer, and other product sales. Operating expenses were $3.1 million in the second quarter of 2025 compared to $2.9 million in the second quarter of 2024, with the increase due to higher wafer…

[Operator Instructions] You have a question coming from Casey Ryan with WestPark Capital.

This is an exciting update. I did spur some questions, particularly around Stellantis. I think how do we think about the opportunity with them? I think you're mentioning platform, which is helpful. But to sort of boil it down for us in the public, I think Stellantis has 16 brands, but you mentioned it's maybe for an EV vehicle, but what's the right way to think about your exposure? Like could you be exposed to all 16 brands? Are you exposed to all EVs within the 16 brands? Or is there some other way to sort of simplify what the opportunity there is?

Yes. I mean our understanding from discussions with them is they want commonality across their brands and their EV platform. So you would see us in multiple brands that people would recognize. There will be some brands like Maserati, where they will probably go with higher cost solutions like silicon carbide, where cost is not an issue, and people aren't worried so much about range because it's a different application. But they really want to have a common EV platform since they've got to continue to support their combustion vehicles, they don't want to have multiple iterations for every brand of what their new EV products are going to look like. So it gives us a pretty broad opportunity across a broad range of mid-sized vehicles for new brands.

So it's certainly fair for us to think it may be multiple brands, maybe not all 16, but certainly more than 1, and then multiple vehicles possibly.

They clearly plan on it being multiple brands. They've made that very clear to us. And part of this work that they're -- they've told us that we're getting a purchase order for is to also start to drive some commonality even within the EV. Originally, the drivetrain and EV contactor programs were very separate. They were going separate paths. And this work is to actually converge on the semiconductor and packaging design prior to getting the contactor program awarded, because they really want to have that same solution in both of those parts of the vehicle. So it gives us commonality in what we are going to provide for multiple applications within the EV.

I think in the past, we've talked about the contactors potentially being in the hundreds of dollars of content per vehicle. If you were in the -- like total vehicle across all these opportunities, I mean, would that number sort of move higher to sort of closer to 4 figures? Or would it still be in the hundreds, but possibly higher than the contactors alone, I guess?

Yes. So we estimate the total power semiconductor content in the EV about $1,100. The biggest part of that actually is the drivetrain inverter itself. EV contactor to maybe $300 of that content. So it's most of the content. The other content you're looking at is things like the onboard charger, which may use lower-power devices or MOSFETs. But for us, it's really the drivetrain inverter. I think I heard Onsemi at one point say they had about $750 of content in the drivetrain inverter for power semiconductors. So I've heard that number out there, but it's several hundred dollars for the inverter.

One thing that we've talked about, and like I think moving to commercial revenue is a very exciting thing for the second half of '25. But I'm curious, in terms of your design win opportunities and how they come to you, how would you classify those in terms of volume of opportunities? Just as we're curious about all the applications of your technology, would you say that known design win opportunities for you sort of number in the like 10, because we're sort of talking about automotive people primarily? Or are they potentially in the hundreds of thousands in terms of where you guys could be consumed or sort of considered as an upgrade solution?

Could you clarify that a little bit, Casey, on--

We'll know. I'm just saying how many design opportunities are you guys seeing out there in the marketplace separate from what you've talked about already, to sort of what's on your sales pipeline board, essentially? Like how big is that funnel is what I'm sort of curious about.

Yes. I mean it continues to grow. I mean if you look at the automotive side, it's more discrete because there are just less players there. So there's 5 global auto OEMs, 4 of which are in the top 10, and 5 Tier 1 suppliers. Now if we look at the industrial side, there's many, many more because there are a lot of companies that we are working with that are interested in solid-state circuit breakers. They range in size from very large companies that people would recognize of -- and I'm not saying these are them by name, but they would be companies like a Siemens or an Eaton or Schneider, to some midsized companies that are also looking to try and find a way to take market share from the big folks. So our earlier design wins are clearly going to be on the industrial side. We'll get funded programs through the Tier 1s and the automotive companies since their design cycles are longer. But a lot of our effort right now is really focusing on the industrial applications where we'll have our first wins.

And then you mentioned silicon carbide and the cost issue. I'm just curious, technically, and how you guys feel about this, would customers prefer silicon carbide cost not being an issue? Or is that not always the case? And not that silicon carbide will ever get the cost parity with your solution, but I'm just curious how customers think about that.

I'll use our first design win customer as the example. The breaker that they sent to us that was silicon carbide, cost was a problem, but the biggest issue was it got too hot. It wouldn't meet the standards even at 20-amp unidirectional applications. So we were actually to give them breakers back that had 3x the power density. They were 63 amp breakers that we sent them back, and they were bidirectional, which is what they need, particularly on DC applications. The temperature rise in them meets the codes and standards. So it's heat is the big problem because the conduction losses are high in silicon carbide.

And then kind of the last question. You guys also mentioned in the script data center opportunities. Can your products be integrated into an environment, say, a data center, as a hybrid solution? Like can some of your products be consumed, but also be in a mixed environment with older technology as well?

Yes. What we're seeing is they're prioritizing where there's really a need for speed that impacts the quality of the power on the data center. So speed of transfer switches, speed of breakers. We don't expect that a given data center is going to swap out every breaker all at once. They'll do that in kind of a staged fashion. So you'll just have one part of the data center that will perform at a different level and have different diagnostic capabilities than what it may have been built with 5, 10 years ago.

So there's ample opportunity in existing markets and not just in greenfield builds, essentially. That's what I was curious about.

Yes. I mean for data centers, the big issue for them is electricity is the biggest operating cost. So while they want to have faster-acting solutions to enable them to maximize their uptime, waste heat that comes from some of the solutions that are out there that are silicon carbide-based doesn't help them because it raises their electricity usage, which works against their business model. So I think there's a great opportunity for us as people look to modernize the data centers to actually replace things that are existing as well as be in the new builds.

Well, that's another great market for your technology. I think that's it for me. But look, this is a very exciting update. I think we're getting to sort of an important demarcation line as you get closer to commercial revenue.

I would now like to turn the floor over to Jeff Christensen to take any questions from the webcast. Jeff?

Thank you, Kelly. Our first question is a lot of that was submitted by investors is a lot of semiconductor specialists agree that the technology is excellent, and it's a game changer for niche solid-state circuit breakers, EV hybrid applications and more. What are the challenge to closing sales? Are there any technical challenges? And are there any -- are there 1 or 2 issues the company needs to overcome? Or are there issues more individual for each company?

There's -- there haven't really been any technical challenges. The biggest issue really is just the education process. You think about things like silicon carbide MOSFETs, they've been around for 25 years. So engineers learned about them in school. They've worked with them previously. Our technology is new. So you've got to get the engineering community through that education process. You got to get devices in their hands, get them in the lab, working with them, get comfortable with them. It's also part of why we do things like present papers at the Applied Power Electronics Conference every year. We've got an article coming out in the IEEE magazine this year to really help discontinue that education to the technical community to get them through that learning process, so they're comfortable adopting a new technology.

Thank you. Our next submitted question is, what is Ideal Power doing to drive sales ramp and increase product awareness?

Yes. So for us, we're taking really several paths to market. We have our own internal sales team. We have distributor relationships. We have sales reps. We have a new partnership with Kaimei, where they'll actually be selling our products alongside their own. We're also continuing to increase awareness in the technical community. Dan had mentioned there's going to be an article about B-TRAN and solid-state circuit breaker applications in the next issue of IEEE magazine. We also actively attend trade shows. We've been to APEC and PCIM earlier this year. We'll be at the upcoming ECCE conference in Philadelphia. And we also recently launched a global solid-state circuit breaker campaign that incorporates the test results that Dan had mentioned related to our first design win that show that B-TRAN significantly outperforms silicon carbide MOSFETs in breakers. So this advantage really carries over to other solid-state switchgear applications like EV contactors, another application we're targeting. So we're really taking a multipronged approach in terms of getting B-TRAN into the trade press and also just really increase awareness.

Thank you. The next submitted question is, I'm new to Ideal Power. In simple terms, what is an IGBT and what are the advantages of Ideal Power's B-TRAN compared to an IGBT?

An IGBT, it's a unidirectional semiconductor device that functions as an electronic switch that controls the flow of energy for various applications. IGBTs are used for high voltage, high current applications like power converters for electric vehicles or EV charging or energy storage and renewable energy, industrial motor drives and other industrial and utility applications. IGBTs are a big market. It's about a $10 billion market today with a lot of growth expected over the coming decades just due to the increasing electrification of society. The primary advantage of B-TRAN over an IGBT is that B-TRAN offers improved performance and bidirectionality. And bidirectionality is increasingly important as we use batteries more and more because you need to control the flow of energy during charging and discharging of the battery. So you see solar coupled with energy storage, you see electric vehicles, you see EV charging with backup batteries for buffer capability. So in terms of performance, B-TRAN has significantly lower conduction losses and it's more efficient. So it produces less heat than IGBTs. That allows OEM products to be smaller and more efficient because the size of a lot of power electronics, like a power converter, are driven by the need to dissipate waste heat. So it really comes down to being able to provide a high-level performance. And the big issue really for a lot of these bidirectional applications is any time you're using an IGBT, you need 4 devices to make a bidirectional switch. You need pairs of IGBTs and diodes to control the flow in either direction. So there's more parts that will fail, there's more cost, and there's significantly higher loss, about 5x higher conduction loss for bidirectional switch using conventional things like IGBTs. So you end up with a more efficient solution using B-TRAN and one that can actually be lower cost because it's a lower cost bidirectional switch and lower lifetime cost for the OEMs.

The next question is, when will Ideal Power get to cash flow breakeven?

Yes. So for us, it really depends on product and customer mix. Obviously, the pace of adoption is going to influence that. But what it really comes down to is it only takes a few key design wins for us to get to cash flow breakeven. We're engaged with large global companies that are evaluating our technology for their applications. And landing even a single design win can generate millions or even in excess of $10 million in revenue annually for Ideal Power. So it just comes down to, again, which design wins happen at what time, and just really the pace of adoption, but it will not take us much to get there. We can do it with just solid-state circuit breakers. Obviously, we'll have contributions from development programs around electric vehicles, but it's really the industrial markets will get us there.

So I'll ask the next question. It's about the auto qualification. So I'm going to combine some questions that were asked by a couple of different people. But what can you repeat and clarify -- can you repeat and clarify results on automotive testing? What does prequalification mean? And how are you able to make modifications during the testing?

Sure. Good question. When you go through automotive qualification, you have to submit many packaged devices from multiple wafer runs. So it can't just be you cherry-picked the best devices from a particular run. You have to show that you've got commonality performance across several wafer runs and many devices from each of those runs. So what is a good practice is to actually take devices and take them through those test cycles before you actually do all the runs for official qualification. You can do with a smaller number of devices. It helps you find out, are there any issues with your packaging design that can't withstand maybe humidity or temperature, because auto qualification testing is fairly expensive, and it takes many, many, many, many devices, hundreds or a couple of thousand devices to get through it all. So it's really -- prequalification is to make sure are there any design issues you need to be aware of for the devices? Or are there any areas with the packaging? And the one thing that we saw that we want to improve was are the devices that we've had packaged so far have not had tooling for encapsulation, and we think that would be a thing that would make the package even more robust. So we did some things that actually also will help us with a design that will be better suited for -- on the packaging side for high-volume production in terms of making it easier to assemble. So prequalification just gives you that early look into any issues you might have, so that before you run all the wafers and do all the packaging for the hundreds of devices that go into testing, you've already addressed those issues and you know you can pass with a good degree of confidence.

And then another question regarding the qualification is, does the process, as we move to finalize that qualification, including the prequalifications, is that -- any comment you can make about the inflow from industrial -- other industrial automotive customers that were previously hesitant to jump into the new technology?

Yes. So I think overall, the more test data that you have that you can share with customers, the easier it is to get them to adopt the technology. So obviously, we've generated a lot of test data through our works with Stellantis to date. It's similar here with our first design win customer. We have some really great data now we can share for solid-state circuit breaker applications. We have -- we had no die failures through prequalification. We can share that data with industrial customers. So we think all of these things will help adoption. And then when you get to actual auto qualification, I mean, that should certainly help because the automotive standards are much more stringent than industrial standards, has extremes of median temperature, you just don't have the industrial test. So all of those things should act to really help with adoption.

And just one comment on that. Part of why we did this is to generate some of this data because when you do have a new technology, there is a -- I won't say reluctance, but customers are conservative. And people that understand IGBTs, for example, understand that the most common reason that IGBTs fail is a fail of the wire bonding that's used to bond the die to the package. Since we don't use wire bonding, we have a different approach in terms of how our package comes together. We wanted to generate the data that showed that not only do we pass the 15,000 power cycles needed to meet auto qualification, we kept running them. And to be able to go to those customers and say, not only do we pass that criteria, we've passed 50,000 power cycles without a failure. It really helps with the technical customers that you're working with to be comfortable that the device is actually ready for adoption for their application.

Thank you. There are many submitted questions from investors, and thanks for that. [Operator Instructions]. The next question is that was submitted is you've definitely shown a lot of the commercial progress. The stock price seems to be lagging the progress you made. What do you think the Street is underappreciating or overlooking at this point?

Yes. I would say, given the macro trends that are out there, things like renewable energy, EV adoption, proliferation of data centers, I mean they're really driving the increasing use of power semiconductors. So we think we're commercializing our technology at a great time. We certainly have near-term opportunities to secure agreements with multiple large global companies beyond just our first design win customer in Stellantis. We bring a solution in silicon that provides significant performance advantages over conventional technologies. It's enabling for applications like solid-state circuit breakers and EV contactors. So while we're not going to sit here and speculate on why the Street is not valuing -- really valuing the enormous opportunity ahead of us, we would expect that to change as we continue to announce some of these design wins, some more custom development agreements, and we start showing revenue here in the coming quarters. So for us, we can't focus on what our specific stock price is on a given day or what the market is -- what's in favor or not with the market. It's really focusing on executing and getting those commercial announcements out, and we expect that it will take care of itself.

The next submitted question is, which market do you see that will contribute the most to the company's initial revenue ramp?

It's clearly going to be the solid-state circuit breaker market. We've got so many companies that are engaged with us now. We've got the first design win with the customer. We know that they've got other plans for other products. And fortunately, the design cycles on industrial products are significantly shorter than what you see for getting through the long design cycles on the automotive side. So our focus is really going to remain driving the opportunities in the solid-state circuit breaker market, the closure, because once the first company moves forward, you're no longer the first person to do something. So I think it kind of takes some of the pressure off some of the other customer teams to say, okay, people have already been through this evaluation. I'm not missing anything, and I'm comfortable with making sure I've got a competing product.

Do you think -- the next submitted question is, do you think we will be -- our most successful markets could be outside the United States, especially given the recent shift in the administration away from EVs?

I think that's certainly shaping up to be the case here. Asia, in particular, tends to adopt new technologies quicker. The first design win that we've got is an Asian customer. We're seeing multiple Asian customers that we're working with, even in the Tier 1s that we're working with now. EVs -- I mean, it's a global opportunity, but I think we will see much of what we are doing on the circuit breaker side and on the EV side start to materialize in opportunities outside of the U.S. first. And then in general, U.S. companies seem to move more slowly than what we see for a lot of the Asian companies we're working with, which is fine. It will just they'll come in behind it with their own version of the products. But it's a good insightful question there. I think we will see the growth first outside of the U.S.

Okay. What is the cost of -- the next submitted question is, what are the cost of 4 devices in a traditional IGBT that B-TRAN replaces versus the cost of the B-TRAN?

Yes. So at scale of B-TRAN, a single B-TRAN should be at about a 10% or 20% premium to a single IGBT. So if you're looking at a bidirectional application, I mean, it's significant cost savings because you need to include 2 IGBTs and also have 2 blocking diodes in that solution. So B-TRAN is actually a much less expensive alternative in terms of first cost. And also, if you look at lifetime cost, it's also obviously going to help because you're going to have smaller OEM products, you can have less surface area to dissipate heat, less complex thermal management systems, overall smaller OEM product designs, just because there's lower losses. So it's really both not just a first cost advantage when you're talking about bidirectional applications, but it's also a lifetime cost advantage as well.

The next submitted question is, of the companies you're currently working with, how many of you are you continuing to have engagement with in the last 6 months, and the other in the last 12 months. So any one of those time frames?

Jeff, can you repeat that? It's unclear what you're asking there.

Yes. So of the companies that you've said you're currently working -- you're working with, you've worked with, how many have you engaged with in the last 6 months or 12 months? I guess the question is it all of them? Or the question I think is, is it all of them or any of them missing now?

No one's missing there. Some of them, particularly large companies, move slowly, but all the companies that we have been engaged with, we continue to be engaged with.

And then there are -- the next submitted question is there a recent marketing literature about a new technology called an insulated gate transistor oscillator, or IGTO. Would this technology be directly competitive to B-TRAN?

I did look at that. We had our guys look at it, too. There's really not much technical data available. There's no data sheets or anything for the product. But based on our review, it looks like it's an incremental improvement to a unidirectional IGBT. It's also not clear how it would apply to the overall IGBT market because the things that were done there will certainly create challenges to be able to reach both high voltage and high current. It's part of why you don't see MOSFETs used for high voltage and high current. It incorporates some of the same technology that limits where MOSFETs can go. But at the end of the day, it's a variant of an IGBT. So you would still need 4 devices, pairs of this improved IGBT and diodes to make a bidirectional switch. And as a result, the conduction losses would be much higher than what you would get using a single B-TRAN.

The next submitted question is, please update us on the future expectations with large power global management companies that you're working with.

So again, I'm not sure I understand the question, but on the companies that we're looking at power management market leaders, I mean, they're really looking at things right now like solid-state circuit breakers, right? So there hasn't been a change necessarily in the last few months. I mean it's obviously -- we're continuing to educate some of those companies. They're evaluating our technology. They have it in the lab. So we're continuing to make progress, but their expectations haven't changed. I would say the one thing, maybe in that regard, is we've had some potential customers that are a little bit surprised that silicon carbide doesn't perform as well in that application as they may have expected it to, because it's considered a high-performance product. But -- the reality is conduction losses are not the strength of silicon carbide MOSFET. So that's where our technology has a significant advantage at a lower cost point than silicon carbide, because it's not just that silicon is cheaper than silicon carbide, it's also that we really outperform silicon carbide in that application significantly.

Thank you. That concludes our question-and-answer session. I would now like to hand the call back over to Dan Brdar for closing remarks.

I just want to thank everybody for participating in today's call and for the really good questions. We look forward to sharing B-TRAN commercial announcements before our next update call. Operator, you may end the call.

Thank you. This concludes today's conference. All parties may disconnect, and have a great day.
