Full transcript - Barclays 39th Annual CEO Energy-Power Conference 2025:

Heath: So we know of too many companies quite like Aspen Aerogels. We often talk about transferable skill sets and energy services, products and services and traditional energy that are in that now have new emerging markets and new energy. Well, no one has done it quite as well or as quickly as Aspen Aerogels with an established product line in traditional energy that has seen a step change in revenue as a supply to EV batteries. I’d like to introduce Mr. Ricardo Rodriguez, who joined Aspen in November 2021 and serves as the company’s CFO and Treasurer.

Thank you very much for joining us today.

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: Thanks, Heath. Thanks for having us. So, Neil that it feels a little bit like we’re on a paddleboard here for setting up the Baker Hughes and Carnival Cruise ship just won by. So thanks for having us, we really appreciate it. Absolutely.

So maybe

Heath: we just start with the uninitiated, what is Aspen Aerogels, can you talk about your business and sort of the core product behind the story?

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: Absolutely. So the core technology of the company is materials platform and aerogels were invented in the 50s. They’re the lightest material that humans have created. And in our case, what the company really pioneered is a practical use for silica based aerogel. And when you an aerogel is an open pore structure material that when you use silica as the base for it, it traps air in a very unique way unlike any other thermal isolator.

And so that makes it three to 10 times better than any other competitive form of thermal insulation that you could use along with a bunch of other benefits like it being fireproof, hydrophobic, etcetera. And in the first twenty years of the company’s history that proved critical for energy industrial infrastructure. So if you think about oil refineries, when you where you only have so much space around the piping to isolate that thermally and none of the other materials can do it, That’s where we started to come in. Then we added another product to do the same thing for very cold processes or cryogenic processes within LNG facilities. And then in subsea piping, so pipe and pipe insulation, that’s a market that we pretty much have to ourselves where you need the insulation to be as light as possible while still isolating the pipeline from very cold water temperatures.

And then to your earlier point on why we’re really playing the energy transition, so while it’s the same material or variation of the same material around the time I joined the company almost four years ago, General Motors came to us looking for a solution to protect vehicles and batteries from thermal runaway inside of the cells of electric vehicle batteries. And if you don’t know what thermal runaway is, you may remember those Samsung tablets that were exploding on people’s bags and particularly on planes. And in essence what was happening there is when you put a tablet in the plane, the cabin pressure is such that you actually press the positive and negative side of these battery cells, you’re crossing a short inside of cell and it goes up and the lithium ion materials and some of the other stuff inside of itself is pretty flammable. And so General Motors looked at what the other automakers were doing when it came to really pushing every last bit of performance and energy density out of these cells. And given the size of the cells and how much they were trying to get out of them, they knew that they had to put some form of passive installation that took up as little space and weight as possible.

And that’s where our team actually showed up first with some of our energy industrial products and they would go back to their hotel rooms at night, shading it down to the minimum thickness that GM could get away with and those became the first EV thermal barrier prototypes. And to put it in perspective, we did roughly $145,000,000 of revenues last year on the serving our traditional energy infrastructure markets with these roles of installation. And then our EV thermal barrier business basically grew from about $7,000,000 of revenues in 2021, which is when GM started production to over $300,000,000 of sales last year. Being a material an advanced materials platform protected with over 400 patents, a pretty intricate process that has a lot of know how that is very tough to replicate. We actually set the company out to operate with a target gross margin of 35% plus gross margins and to deliver at least 25 EBITDA margins.

And as we’ve grown, we’ve geared the company to deliver that and more, we deliver a little bit more than that last year at the gross margin level. And then I think this year, we’re taking a bit of a reset as you’ve indicated in your research around the volumes for GM, right. The election has been pretty impactful in terms of the policy that’s driving EV volumes here in The U. S. Temporarily.

Even though consumer preferences we believe are still going to prevail in the long term. But that’s in essence us today. We expect to do just over $300,000,000 of revenues this year across both segments and to still be generating meaningful EBITDA and we’ve got a cost structure that’s now even better than what we delivered the $450,000,000 plus of revenue with last year.

Heath: Can we talk about a little bit more about the aerogel product itself? You’re not the only one that has aerogel. So how is your aerogel product different than some of the other I think there’s a couple other companies that make an aerogel type product? And also what’s the IP? How do you protect the IP around this?

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: Yes. So we were looking for additional capacity to supplement our ramp in 2023 and actually looked at other aerogel companies. And I would be surprised if you add them all together to get more than $50,000,000 of revenues even in China. The main differentiation is quite a bit of evolution around the chemistry and the process that makes ours mechanically more way more pliable than any other aerogel material that’s been touted. And then also when it comes to delivering the thermal isolation and the right composition to deliver this open structure that I mentioned, there are quite a few controls in the process that we’ve developed over time that give us the ability to deliver a product that just performs at a 3x better than some of the comparable materials that we tested.

And the proof is that the Western OEMs have tested this aerogel material and have not awarded it any business after having tested ours and given us the business. We actually audited a lot of these potential aerogel suppliers, as I said in 2022 and 2023 as we were looking for additional supply and then spent over a year getting our partner in China to provide us with some external manufacturing facility because they needed quite a bit of handholding on the process side and the trade secret side in order to deliver a product that could have our brand name on it.

Heath: If we can talk about the energy industrial business a little bit. First, I want to talk about the end market. So you touched on them. Can you kind of go through the major drivers for the

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: aerogel products in the energy industrial business? Yes. So on the energy industrial side, we basically have three applications and then I’ll go through the markets. As I mentioned, the main applications are hot processes. So we have a product called Pyrogel and a couple of families within them that go into refining.

Then our Cryogel product goes for cryogenic process and that mostly ends up in LNG facilities, sometimes even covering entire tanks with an LNG facility. Other chemical processes, last year we did a carbon capture project. So wherever you’re operating at very cold temperatures and you need to protect the energy loss, we can come in. And then the third branch within the energy industrial side is the pipe in pipe installation for subsea pipelines that I mentioned as well. We sell the product through distributors.

These are relationships that we’ve built over the past twenty plus years. And now more than twenty years into this journey, we have an installed base of about $1,500,000,000 of product. And if you think of the maintenance cycle at these facilities, part of the maintenance cycle includes cutting up insulation to inspect for corrosion. And so that drives a healthy base load of business for us, especially on the Pyrogel side as this insulation is cut up and then being replaced, That gives us an opportunity to replace materials like mineral wool and perlite as the piping gets rearranged and there’s an opportunity for us to take share from them. And then, of course, whenever a new project is announced or started, we work pretty hard to come in and capture additional market share in that and ends up driving about a good third of our revenues in a given year.

Heath: When you kind of pull it all together, how do you see sort of the longer term growth target of energy industrial?

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: Yes. For energy industrial, we’ve said that growth between 10% and the low teens would make sense. That’s I think the onus is really on the team to develop that not just on the three applications that I mentioned. But it’s very interesting. As we go around the world, you’ll find these niche applications that people end up using product on.

Like not that long ago, I actually found out that the Formula One teams were using our Pyrogel product to cover the exhaust of the race cars. I mean very little product, but it really makes you think, wherever there’s energy loss, we have a role to play, right? Or wherever there’s performance that could be gained from preventing energy loss, we can be there. The company in 2021, right as the opportunity on the EV thermal barrier side came along, actually built a building materials installation segment and it got a meaningful amount of revenues very quickly only for them to us shut it down in order to supply the EV thermal barrier opportunity. But I think really the onus is on the team over the next twelve to eighteen months to assess all of these additional applications, invest a little bit of OpEx, get some revenue and return and then really get that snowball effect outside of the three segments that I laid out.

And I think that in combination with the installed base that we have and new projects can definitely drive 10% plus growth in this segment. I did see Brett talking about the Aspen Aerogel products. He was talking about it,

Heath: so that’s pretty interesting. Shifting over to the thermal barrier side, it’s been a really interesting business that kind of came out of nowhere. Can you talk about the origins of this? This is it kind of took everybody by surprise and I never even heard of Thermal Runway before. Can you just talk about the genesis of this of how GM started using your product?

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: Yes. I mean, so GM was actually familiar with aerogels because a long time ago they looked at aerogels as a potential heat shield barrier on the core of that. If think about internal combustion engines catch on fire all the time and if you could have better heat shield made of a material like pyro gel, would be amazing. But they determined that for various reasons, it didn’t make a ton of sense. But then GM actually cold called our team in 2020 saying, hey, we’re jumping into this EV investment with the Altium platform at the time.

They had a target of having the capacity to produce a million EVs by 2025 And they in essence came to the team looking for a solution. And if you look at what used to be put into electric vehicle batteries before, it was in essence this polyurethane foam that is there for mechanical reasons, right? So when you’re putting the battery pack together, you want the cells to sit there firmly without moving and shaking around because that can then cause these cells to fail. But they wanted us to replace those foams with a foam like material that delivered all the properties that we were known to deliver on the energy side, right? So great thermal isolation, fireproofing and then they added the third leg of the stool, which was the mechanical properties.

And that’s where a lot of the work went into develop those mechanical properties to make the material thinner. That in turn gave us an ability to produce a lot more get more capacity out of our assets. And that’s how we ended up with the thermal barriers as we know them today. The product releases some silica dust and GM said we don’t want to deal with the dust inside of the battery pack plants. And so we came up with a method to encapsulate the rectangles of aerogel and that cutting encapsulation and dimensional testing is what we set up a couple of facilities in Mexico to do in 2022.

And I mean, now, we’re at the rate where we’ll produce over 90,000,000 parts in a year.

Heath: So what are other EV or battery OEM makers use to prevent thermal barrier It’s a thermal runway.

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: Yes. I mean, it’s a multi dimensional problem. The main thing that they do is they actually throttle back the battery, right? So Tesla, the current battery architecture for better or worse was guided by decisions that had to be made in 2006 and 02/2007. And cells available at the time were cylindrical laptop battery cells, right?

So that put Tesla on a path where they’re set on using cylindrical cells. But if you actually look at the EV market today, with China, 91% of vehicles out there have pouch or prismatic cells. So only Tesla, Lucid, Rivian and some lingering BMWs are using cylindrical cells. And on those cylindrical cells, you don’t necessarily have a lot of space to put a thermal barrier like ours and so you have to sort of play around with probabilities as you’re charging, discharging and using the vehicle. And so that means that if you or I were to buy a Tesla, theoretically that car could have maybe 400 miles of range, but you’ll see that the EPA cycle rating is probably for like three fifty miles of range.

And then in the ebbs and flows of daily driving with different temperatures, we will probably be getting about two eighty to two ninety miles of real ranges that battery is throttled back through the controls of the battery. What we’re seeing with GM is that when GM advertises a vehicle with three ten miles of range, you’re getting three ten plus miles of range. They’re able to use regen more aggressively knowing that we’re there as passive layer. They’re able to heat up one cell knowing that that heat won’t spread to the next one. They’re able to use charging a lot more aggressively.

You’re seeing now vehicles with 800 volt architecture that enable faster charging and generally there’s a thermal barrier in those vehicles enabling that faster charging without as much risk. And so, I think OEMs are starting to see that there’s quite a bit of opportunity that unlocks itself when it comes to maximizing the performance of the battery cells when you have a passive layer of insulation like ours. So when you get into the fast charging, does that increase the risk of thermal runaway? It does significantly, especially at either very cold or very hot temperatures.

Heath: What do the Chinese use? The Chinese, some

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: of them play this game of probabilities that I mentioned as well and some of them on very high performance applications use this aerogel that we discussed that tends to be stiffer and provides less thermal isolation. And sometimes we’ve seen several videos of those Chinese EVs or buses catching fire and the materials there and it buys you time, but not as much as we think it could.

Heath: So aside from GM, can you talk about some of the other kind of European EV manufacturers and the opportunity set there? Yes, we’ve

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: been supplying Toyota as well since 2021 on the BC4X and the Subaru Solterra and the Lexus variant of that vehicle as well. We also have an award from Audi for their next generation A6 platform. We also have an award from Scania, Volvo Trucks with Stellantis for the vehicles that will be equipped with the cells made by ACC in France. That’s actually the program that we’re looking forward to launching here in Q4 of this year and that will ramp up next year. And then Porsche also awarded us business for the replacement Boxster and Cayman platform.

Again, another high performance EV that will really look for fast charging and fastest charging. And then we also announced an award with Mercedes Benz, so Daimler and that will kick in, in 2027 for those vehicles that will also be supplied with those sales from ACC.

Heath: So when you talk about awards with these various auto manufacturers, what does an order mean? Is that just like a call like you now have an agreement with them, but do you actually know what the numbers are going to be or is it more

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: of a call out? No. So we actually have been given the business and we’re designed into a specific vehicle that is about to start production. We have agreed to pricing. They’ve given us indicative volumes.

Several of us have worked in the auto industry before at the company and we know that you can’t totally take the OEMs volumes at face value. If you add up the volumes they give you in the car market, it’s five times the size of the car market and so we’ve been pretty eyes wide open about sizing this correctly. If we would have believed the million units by 2025 from GM, we probably wouldn’t be here today, right? But we actually did get that number right. Like we said that in 2021 that, that number was going to hover between 200,350 vehicles in 2025.

And so yes, I mean, it basically means that you have to start committing a little bit of capital to get ready to supply those programs for when those vehicles start production and that we’ve agreed to pricing and that we’re designed in. And that, I believe, gives us quite a bit of staying power because to design us out, you need a lot of development work and capital to, in essence, make a change, right? And you also wouldn’t want to be the engineer that took out the critical safety component that’s addressing thermal runaway.

Heath: So for me, on GM, it’s obviously outside my lane. I rely on my colleague, Dan Levy, who covers GM, who talks about kind of

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: the production forecast of EVs.

Heath: What are they telling you now? Actually, maybe just step back a little bit of kind of been a lot

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: of volatility over the last couple of

Heath: months with the big bill and other things happening. So kind of what’s been the messaging from GM? How are you kind of seeing this trend? What are they saying to you right now?

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: Yes. So I mean, GM back in even before 2021 really put itself in the path to get a strong of a foothold as it could on EVs, right? And they invested pretty much their entire market cap on EV capacity and EV launches. I actually think they’re betting even a brand like Cadillac on EVs. If you look at all of the new product offerings from Cadillac, they’re mostly EVs.

And some of the vehicles that we supply, which at this point, there are now about 17 nameplates with GM, they’ve actually gotten a strong foothold in the market. The number two EV sold in The U. S. After the Tesla Model Y is actually the Chevy Equinox. And so we’re actually pretty encouraged to see GM gaining share, sometimes even over indexing the share that they have on the coasts of The U.

S. On their internal combustion vehicles getting new customers. There’s also quite a few customers that are leaving their Teslas to look for an alternative and GM is there ready to take them. Having said that, yes, I think the election was kind of transformational in many ways relative to some of the energy policy and the fuel economy standards and fuel the emission standards that the OEMs were being held to, especially for 2025 and beyond. And so now the OEMs don’t have as much of an incentive for having a certain percentage of their new cars sold in The U.

S. Being EVs. In fact, quite a bit of that regulation is being tested right now and removed. But at the same time, we do see GM and what they tell us is that they’ve invested so much in launching these vehicles. They’re getting customers that they otherwise wouldn’t get and that that will have them really focused on maintaining that share even after the $7,500 credit for consumers has gone here at the end of the month.

The incentives on the production side for making EV cells and assembling EVs in The U. S, I think will actually only increase with the Trump administration. And so it’s kind of a balance. The consumer credit, if you look at the data for EVs, it actually just enabled the OEMs to increase the prices by about $5,000 on average. So consumers didn’t necessarily get that benefit unless they were really leasing the vehicle, getting a cheap lease.

And with the Trump administration, we actually see quite a few incentives for making the cars in The U. S. With U. S.-made content and then that favors us with our USMCA content that we are selling into these CVs. So I mean, I think we’ll have to make a bet on where the volumes will end and kind of visit it next year.

But we don’t think that it will be a bigger reset than what we saw from last year to this year in terms of volumes for GM. And then we obviously have all of these other awards with other OEMs that I mentioned in 2027 contributing to the P and L pretty favorably. And again, with this 35% plus gross margin target, which in the auto industry is relatively rare, we really gear the company to pay back all of the capital that we’ve deployed to chase this opportunity with attractive margins.

Heath: You had to a lot of supply chain jujitsu over the last couple of years, you still maintain the 35% you’ve got to the 35% operating margin target. Can you talk a little bit, so all of your thermal all of your energy industrial is now manufactured overseas? Most of it.

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: So except for the part that is now that we have some extra capacity in Rhode Island, we are making some of The U. S. Product here in The U. S. With a lot of raw materials also from either The U.

S. Or Europe as well. But yes, for the rest of the world, our energy product is made by the external manufacturing facility in China.

Heath: So are you confident to get back to those 35% margins? When do you think you

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: can get back to there? Yes. I mean, we showed good progress towards that between Q1 and Q2, right? So I think that right now the company is geared in essence at that $85,000,000 per quarter revenue run rate, we can deliver the 35% gross margins. It’s a lot easier to do it on the energy side.

We delivered 36% gross margins here in the past quarter, even though the demand rate was nowhere near what it would need to be in order for us to be at 85% in total. And then on the EV thermal barrier side, if we were doing $60,000,000 of revenues per quarter, we would have 35% gross margins and we did 55 So million this is a question of volumes? Correct. Yes, I think it’s just the fixed cost absorption, which the team keeps working on reducing further and further. And I think that will yield benefits in definitely 2027 when we expect the demand to truly be there, even higher than what we did last year.

Heath: Great. Well, why don’t we leave it there, Riccardo. Thank you very much

Ricardo Rodriguez, CFO and Treasurer, Aspen Aerogels: for your time. Thanks for having us. We appreciate it. Thank you very much. Thank you.
