Hello, and thank you for joining us for Hyliion Holdings Corp.'s fourth quarter and full year 2024 earnings call. Today, I'm joined by our CFO, John Panzer. This is an exciting time for Hyliion Holdings Corp., and we have a number of significant updates to share. Most notably, we are pleased to announce that we have delivered our first early adopter customer unit. While we initially aimed to complete this milestone late last year, it did shift into 2025 due primarily to a couple of challenges we faced that we'll cover on today's call. We continue to make progress with generator testing and validation, and customer interest in our generator technology is growing. We have executed contracts and nonbinding letters of intent with customers for more than 100 Carnot units. We are also pleased to share that we have signed our first letter of intent in the data center sector to supply prime power on-site for data centers, an opportunity for up to an additional 70 megawatts or 350 of our Carnot four-shaft systems of deployments in the years ahead. On our last earnings call, we showcased the Carnot four-shaft system. Now we are pleased to present what the genset enclosure looks like as shown in the accompanying slide presentation. One of the most impressive characteristics of the Carnot generator is its compact footprint for a system designed to provide 200 kilowatts of power. On the front of the enclosure is the user interface that allows users to select operating modes, the power output levels, and enable load following functionality. Since the Carnot generator is designed to be fuel agnostic, users can enable a learning mode where the generator detects the type of fuel or fuel mixture being used and adjusts accordingly. The system is also designed to seamlessly transition to new fuel sources during operation without requiring user input. The four-shaft Carnot generator is positioned at the base of the enclosure with the balance of plant support system, such as radiators, fans, air handling, and controls arranged above it. The Carnot generator is equipped with cellular connectivity allowing it to continuously communicate with the cloud. This enables customers to monitor and control the generator remotely. The rear of the enclosure is where the interconnects for fuel and electricity are located. The enclosure offers customers the ability to have an above-ground or below-ground connection. The Carnot generator provides DC power similar to a battery, which is ideal for applications like EV charging. For AC power needs, an inverter is used to convert the output to 480 volts AC, which is then tied into a facility's standard electrical system. Each generator will be configured to meet customer needs for the intended application. For initial deliveries, some features, functions, and performance characteristics will not be available at launch. We will be making further enhancements to the system as we continue with product testing and validation field trials, and as we receive customer feedback. One added benefit is that since we have a cellular connection with the generator, many system enhancements can be delivered via over-the-air software updates. Now I'd like to provide an update on our plans for 2025. As we shared last quarter, early adopter units are our first deployments with customers. Some units will initially be deployed at our facility for further testing and validation, including customer-specific application criteria, while others will be deployed at their final locations. Our plan is to deliver ten of these early adopter customer units through approximately the middle of this year, which will then be followed by additional deliveries later in the year. As I mentioned earlier, we encountered some challenges related to supply chain sourcing and part processing that impacted our initial customer deployment and set back our testing and validation timeline. One of our primary production activities has been standing up a contract manufacturer for assembling the linear electric motor component of the Carnot generator. We produced the initial components in-house after finalizing the motor's design and developing prototype assembly processes for this part. Transferring our learnings to the contract manufacturer took longer than anticipated, but production is now underway, and we are working on improving throughput. Additionally, while operating the generator, we identified traces of residual metal powder that were slowly being released within the system. The powder was traced to parts that weren't sufficiently cleaned following printing. Parts for initial generators have undergone additional cleaning and are being used as we work on further enhancements to facilitate improvements in performance and metal powder removal. Looking ahead, as we deliver early adopter customer units through approximately the middle of the year, we will also use the time to continue testing and improving the generator and validating operating parameters. This plan also leaves time in the schedule to address other unanticipated issues if they arise. Later in the year, we expect customer deployments to continue, including delivery of units associated with R&D services. By the end of the year, we plan to have produced a couple of dozen generators with the number and pace of deliveries to customers determined by learnings from earlier deployments and the ramp-up of our production supply chain. We anticipate commercializing the Carnot generator sometime in the second half of the year, at which point we may recognize revenue for the early adopter customer unit and begin recognizing revenue for ongoing generator system sales. Overall, we expect to generate revenues between $10 million and $15 million for the year from generator sales and R&D activities. This estimate includes the sale of early adopter customer units.

In parallel, we are actively building our manufacturing capacity and strengthening our supply base to support higher production volumes in 2026. This includes taking delivery of new additive printing machines at our Austin facility, which will continue throughout the year. I'd now like to shift to some exciting commercial updates. We continue to see increasing demand for the Carnot generator, and we are pleased to share that we have now secured customer contracts and letters of intent for over 100 Carnot units. This level of interest well exceeds our planned deployments for 2025 and establishes a strong foundation for 2026. These letters of intent span a variety of market segments, including EV charging, waste gas applications, oil and gas, and now data centers. We are also deploying units with the US Navy and Office of Naval Research with a plan to have the Carnot generator as the power system onboard marine vessels. This past quarter, I'm excited to share that we executed a letter of intent with one of the leading data center cores. The agreement plans for a deployment of two of our two-megawatt systems that we unveiled last quarter are now developing. Each two-megawatt enclosure is expected to house ten Carnot units, accounting for 20 of the more than 100 units we currently have under letter of intent. This data center letter of intent also includes a multiyear opportunity that targets up to 70 megawatts of Carnot generator deployment in the two-megawatt configuration. This opportunity equates to approximately 350 of our four-shaft Carnot units.

We are working closely with this customer as we develop the two-megawatt system and plan the first deployment in 2026. The Carnot generator's high efficiency, low maintenance requirements, low emissions, and noise levels are critical needs for data center customers. The compact two-megawatt configuration and fuel agnostic capability are added benefits in data center applications where space constraints and redundancy are key considerations. We are excited to have a strong launch partner for the two-megawatt product and firmly believe the Carnot generator is a strong solution for powering data centers in the future. Late last year, we were awarded a $6 million Department of Energy methane emissions reduction grant to support the deployment of up to two megawatts of Carnot generators with a goal of reducing methane emissions in the oil and gas sector. We are excited to be working with ElectroGen as a customer for these units and the facilitator of the deployments. Finally, we've recently signed a letter of intent with Al Khouri for the deployment of up to 12 Carnot generators in Saudi Arabia. Al Khouri is a leading provider in the generator market and a key player in the agricultural sector. Initial deployments will focus on powering agricultural farms offering higher efficiency, with lower emissions and maintenance requirements. The customer letters of intent that we've discussed are nonbinding letters of intent and are subject to performance criteria and execution of binding agreements with customers. Similarly, the data center opportunity we discussed is contingent on successful performance and early deployments of the Carnot generator. Shifting now to some further updates on our growth. Scaling our manufacturing capacity remains a priority, and additive manufacturing advancements play a key role in this effort. Last quarter, we took delivery of our first equilibrium additive mLine printer manufactured by GE Aerospace. We are proud to be the first customer outside of GE to receive one of these machines in the US. This next-generation additive manufacturing system significantly enhances our production capabilities, allowing us to print two to four times as many parts simultaneously compared to our existing machines.

We have additional mLine printers on order, which we will be taking delivery of throughout 2025 to further scale our production capacity. Lastly, I am pleased to share that we have begun recognizing revenue for R&D services related to the Carnot generator in the fourth quarter of 2024, totaling $1.5 million. This revenue is associated with the development work under our contracts with the US Office of Naval Research. We closed out 2024 with $220 million in capital. And as John will cover in more detail, we anticipate cash use of approximately $60 million for 2025. This positions us with a strong balance sheet that will sustain us through the commercial launch of the Carnot generator product. Now, I will turn the call over to John Panzer for our financial update.

Thank you, Thomas, and good morning, everyone. Starting with 2024 fourth-quarter results, we recorded revenue of $1.5 million for research and development services related to our previously announced contracts with the Office of Naval Research. Cost of sales was $1.4 million, resulting in operating income of $100,000. In the fourth quarter of 2023, we recorded no revenue along with cost of sales and a gross loss of $41,000. Operating expenses for the fourth quarter were $17.2 million compared to $32.6 million in the fourth quarter of 2023. This decrease in expenses was driven by lower powertrain exit and termination costs, which were $61,000 in 2024 and $11.5 million in 2023, as well as $6.5 million of lower SG&A expenses partly offset by $2.5 million of higher R&D spending in 2024.

Included in the $61,000 of powertrain exit and termination expenses during the fourth quarter was a $900,000 write-down of assets of the discontinued powertrain business that are recorded as assets held for sale on our balance sheet. This adjustment was mostly offset by gains from the sale of other powertrain assets during the quarter. Total net loss for the fourth quarter was $14.4 million, down from $29.1 million in the fourth quarter of 2023. Full-year operating expenses totaled $64.4 million compared to $136.3 million in 2023. Expenses in 2024 include $3 million of powertrain exit and termination costs net of asset sale gains compared to $11.5 million in 2023. As we close 2024, the wind-down of Powertrain is largely complete except for the ongoing sale of assets, which we expect to continue into 2025. Also, to close out the year, we repurchased 10.6 million shares at $1.33 per share in 2024. We suspended our repurchase program in early May and do not expect to execute upon further repurchases but may resume repurchasing activity at a later date if deemed appropriate.

Turning to our cash and investment position. We spent $17.8 million during the fourth quarter of 2024 net of receipts from asset sales and interest income. For the full year, we used $79.6 million of cash, including previously restricted cash, and finished the year with $219.7 million of cash and investments on our balance sheet. Breaking down uses of cash and investments for the full year, spending on core Carnot development activities totaled $41.5 million net of interest income. Capital investments of $16.5 million were directed mostly towards the purchase of additive printing machines and related equipment. As noted earlier, we spent $14 million on share repurchases. Finally, we spent $13 million on powertrain shutdown activities, which was partially offset by $5.4 million of cash generated from powertrain asset sales. Turning to 2025, as Thomas mentioned earlier, we expect to generate between $10 million and $15 million in revenue, including both R&D services and sales of 200-kilowatt systems to customers. Implicit in this assumption is our expectation of commercializing the Carnot generator in the second half of the year when we would also expect to recognize revenue from customer early adopter units.

The recognition of payments as revenue will be subject to the terms of sale and the actual timing of Carnot generator commercialization. These terms include certification and permitting of the generator, as well as achievement of operating performance criteria. Our reported gross margin for R&D services in 2025 is expected to be positive. We may also report positive gross margin for Carnot product sales due to the current expensing of purchased components. We continue to expect that we will quickly drive down production costs as we scale manufacturing volume and as we roll out the two-megawatt Carnot generating system. Therefore, our current outlook for achieving breakeven gross margins on a cash basis is near the end of 2026. We expect that capital expenditures for 2025 will be approximately $25 million or $10 million higher than 2024, as we continue to take delivery of new additive printing machines and other assets needed to ramp up Carnot generator production. We plan to offset that increase with around $10 million of equipment financing. With these assumptions, our total cash outlays for 2025 net of equipment financing are expected to be similar to 2024. As a reminder, we spent $58 million in 2024 for Carnot generator development and capital expenditures, net of interest income. We expect to end 2025 with around $160 million of cash and investments on our balance sheet. Finally, we continue to expect that the capital we have on hand today will be sufficient for the foreseeable future, including commercialization of the Carnot generator sales. Now I'll turn the call back over to Thomas.

The past few months have been an exciting time at Hyliion Holdings Corp., marked by the official launch of our early adopter customer units program. We are encouraged by the strong and growing interest from customers and are excited to have secured a key partner for deploying our initial units in the data center space. Looking ahead, 2025 will be a pivotal year as we focus on executing successful early deployments, refining our technology, and scaling manufacturing in preparation for 2026. We look forward to sharing further updates on additional deployments of early adopter units and the progress of the program on our next earnings call. With that, we'll now turn the call back over to the operator for Q&A.

At this time, I would like to remind everyone in order to ask a question, it appears that there are no questions. I'll hand over the call to Thomas. Please go ahead.

Greg Standley will read. Thank you. So we had a couple of questions that came in prior to the call. The first one for us.

Can you tell us more about this first early adopter unit and who is it going to and where is it located?

Absolutely. So this first early adopter unit is actually going to the US Navy. As you may recall, last quarter, we had announced that we extended our Navy contract for another $16 million. So we've been working with the Navy for multiple years now, and it got extended. And then this first unit is going to the Navy. For a little bit of background, the long-term goal of our relationship is to have the Carnot generator both in military vessels as well as in stationary applications. Actually, pretty exciting. We just recently received the first photos of the ship that will actually be putting the Carnot generator into. It's being built presently. So a great opportunity here. That initial unit will be staying in Ohio initially for further testing and validation, going through test protocols that the Navy has outlined. And then from there, we'll be producing further units, and then it will be going to both ship and stationary applications.

Our question comes from the line of Sean Milligan with Jenny. Please go ahead.

Thomas, good morning. Good morning. I think hey. In the past, you've made some comments about the Carnot's, you know, guess the ability for Carnot to compete against fuel cells, hydrogen fuel cells. I'm just seeing, you know, Bloom announced kinda larger deals in the data center space. So I was just curious if you could remind us like, how Carnot fits in the competitive landscape against fuel cells and then also what we're seeing out of some of these kinda larger prime power natural gas generators that are being announced in data centers also. That's my first question.

Absolutely. So I think you're touching on the trend of data centers, we're seeing this shift to make your own power. Right? And in the past, it's been tap into the grid and just have backup on-site power supply. Now it's moving to make your own power, prime power application. Which is extremely exciting for us because that's where the Carnot generator really shines. Now to your point, we have seen companies like Bloom have made announcements that they're working with data centers. I think recently, they announced up to a gigawatt of deployments with one customer. So what's exciting for us is we see that, you know, we bring forward those alternative new energy benefits like the low emissions aspect, but also bring forward a lot more as well. So a very compact footprint with the Carnot generator, which is critical for the data center space. Even more compact than conventional natural gas or diesel engines that we'd maybe be competing with as well. And then we have the added benefits of the fuel flexibility, the ultra-low maintenance, and then as I mentioned before, the low emissions. So when you tie all those together, we're seeing a lot of interest coming forward from the data center space, which is highlighted by this letter of intent that we announced on today's call. We have established a partner to be the first data center customer to deploy with that two-megawatt system. In that same letter of intent, we've outlined a multiyear opportunity that could get to up to 70 megawatts of Carnot generators.

Great. Is there a way to think about kind of pricing for Carnot versus some of the traditional natural gas generators in the data center space or, like, what maybe where the crossover happens it might be more beneficial to have a Carnot than a natural gas generator?

Yeah. So just to put some numbers to it. So a conventional natural gas engine could be priced for prime power between $1,000 and $1,500 per kilowatt. When you look at fuel cells, we're seeing those are usually around $3,000 to $3,500 per kilowatt. What we've said is, we're somewhere kind of in between those two in terms of price. So we are at a premium to a conventional engine, but less than the fuel cell players. In terms of the ROI though, I think that's where, you know, we see where we shine and, frankly, what customers really care about. Right? They're less worried about the upfront capital cost, more about whether this will be economical in the long run. Since we're able to provide superior efficiency compared to a conventional natural gas engine as well as we expect to have lower maintenance in addition to that. That drives the ROI to look pretty compelling, especially for, you know, some of these programs which are looking at, you know, ten plus years, fifteen plus years where they would be having these assets deployed.

Okay. Thank you. And just to stay on that line of thought, you mentioned that new GE printer prints at a multiple of what you're using currently. I mean, the pathway to drive down your cost can you talk about the visibility you have there in terms of the additive printing, just the scale as you scale up and as you move to some new printers, how can that impact your cost? And then, two, the ability to ramp quickly. Like, so you mentioned 70 megawatts potentially, that data center customer, I mean, how quickly can you order printers and get them operable?

Yeah. So a couple of layers here. So in terms of answering the last part first. We already have more of these mLine printers on order throughout 2025, which will help us with scaling capacity for 2026. The best way to think about it is probably in that six to twelve months from when you order to when you'll be getting additional assets in for more printing capacity. Obviously, the more visibility we can give to GE, our supplier, on that, the better off we are on lead times. Now in terms of cost reduction, I'd break it into two different buckets. The first is how fast can these printers produce units. The great thing with this mLine compared to past printer technology that we are still operating, and it's still great, but the mLine can now print anywhere from two to four times as many parts at once as compared to the past generations of technology. So that allows us to increase throughput. The other nice thing is we already have a roadmap from GE of how that same printer, the mLine, will be able to be improved and modified over time to continue to increase its throughput. We see that as a great platform for scaling up manufacturing for us because not only is it faster today, but it has capabilities as we go forward. The second aspect of cost reduction is working with our supply base. I would actually say, you know, that is probably where the greater focus is presently on our end, you know, right now we've been buying components at kind of that initial R&D sort of cost levels. We need to move into having agreements with our suppliers, volume commitments, driving costs down. I actually think that's where we're going to see more of our cost savings coming from than the printer side just because we're already in an okay position on printer throughput.

Great. I'll turn it back. And if there's not any more questions, I have a couple more.

You announced a letter of intent with Al Khouri. Can you share more about the Middle East opportunity? Will this be your first international deployment?

Yeah. So we're excited to have announced this.

Al Khouri is a leading provider of generators in the Middle East, as well as a dominant player in the agricultural space. These initial gensets will be used in farm applications and other applications to provide prime power. What is exciting about this is that, I recently just did a trip over to the Middle East, and what was very different compared to the US is that most facilities already have diesel engines and generators connected to them. In some instances, we heard stories of a warehouse where they were operating the entire facility off of diesel engines for ten years before that customer was able to get a grid interconnect. That's also very different. The region is already used to using engines, using generators. As we think about deploying Carnot generators there, you're kind of bringing forward this modular power plant, the performance levels of a power plant, but doing it on a small scale, and being able to use fuels like diesel or future fuels that the region is looking to move to like LPG. This allows us to not only give them a solution that has lower operating costs, lower maintenance, but also has this fuel flexibility to meet the goals of the region. We're excited about this opportunity. In addition to that, we have also announced the letter of intent with Jardine, which would be for Hong Kong. We see international markets as extremely promising for this technology.

You know, operating and maintaining the Carnot? Is there some type of service contract there? I was curious because Exelon signed a Prime Power deal recently where they formed a JV with the data center customer and, you know, they're kind of capturing economics more on the power gen side. They just...

I guess, thoughts about the business model moving forward with data centers? Is it just for sales, or is there some other kind of revenue stream that we should think about there? Yeah. So in the beginning, it's going to be us maintaining these generators that are out in the field. Long term, though, we would want to partner with others who already are established in that space and have them take on the maintenance or and/or the end customers that we're working with have expressed interest that they would potentially want to take on the maintenance as well. In the short term, it will be us doing that, but long term, we'd want to work with others to take on that part of the business as opposed to us having to set up brick and mortar facilities all across the US or globally as well.

Okay. And then just in terms of you mentioned some supply chain issues, ramping up the contract manufacturer, and then the metal powder issue. Can you provide confidence that you've worked through those? How long did you have that early adopter system operating at your facilities and working through issues before they go out into the field? Any kind of thought process there would be great.

Yeah. Absolutely. So maybe just to add color to both of the challenges that we faced this past quarter. The linear electric motor is the coil, the magnets in the center of the generator that produces electricity. This is a Hyliion design, Hyliion IP solution. The initial generators we made used components produced in-house for the linear electric motor. We decided to shift that process to a contract manufacturer. Unfortunately, that process just took longer than anticipated. There were some things we needed to work through. That pushed the delivery of the first early adopter unit into early 2025. We've started production and have been receiving units from them, so I think we're in good shape there. The goal over the quarters and months ahead is to scale up the throughput. Regarding the depowdering side, for anyone unfamiliar with additive printing, you're taking metal powder and welding it, which produces the parts. But what that means is there's a lot of residual metal powder surrounding the part that needs to be removed before using it. What we found was that we were getting some metal powder trapped that we weren't able to extract out of the process sufficiently. We changed our cleaning process and identified opportunities for further enhancements that will improve the cleaning as we move forward. We have gotten to a point where we've been able to clean the parts sufficiently enough to start shipping these units. Hopefully, I've provided helpful background on the challenges we faced while getting these early units ready. We believe we're in a good position now, but we'll continue to refine them as we go forward.

Great. Thank you for all the time, Thomas.

Great. I believe that concludes the questions we had. So, I appreciate everyone joining today's call. A lot of progress over the past quarter. Extremely excited to get this initial early adopter unit out there. I'm excited over the months and quarters ahead to continue to deliver additional early adopter units and to continue to update you on the next earnings call regarding how those deployments are going and the performance of the systems. Thank you all for joining.

Ladies and gentlemen, that concludes today's call. Thank you all for joining. You may now disconnect.
