I'll now turn the call over to Amprius Technologies' CEO, Dr. Kang Sun, for his comments. Sir, please proceed.

[Kang Sun, CEO at Amprius Technologies]

Welcome, everyone, and thank you for joining us this afternoon. On today's call, I will give you an overview of our Q1 performance and our recent accomplishments, while also highlighting milestones we look forward to achieving soon. After that, our CFO, Sandra Wallach, will discuss our financial results for the period. I will share some closing remarks before opening the call for questions. Before I give a recap of the quarter, I would like to briefly introduce Amprius to those who may be new to our company. Amprius is a pioneer and a leader in the silicon anode battery space, with over a decade of development experience and a long track record of commercial shipments and customer achievements.

[Kang Sun, CEO at Amprius Technologies]

At Amprius, we develop, manufacture, and market high-energy density and high-power density silicon anode batteries with application across all segments of the electrical mobility, including aviation, electric vehicle, and the light electrical vehicle industries. Today, Amprius has the most complete portfolio of silicon anode material systems in the industry and commands performance leadership with its combination of the battery energy density, power density, charging time, operating temperature, and safety. Across our battery portfolio, we believe that we offer unmatched performance amongst commercially available batteries.

[Kang Sun, CEO at Amprius Technologies]

Amprius has been delivering commercial batteries to the market with up to 450 Wh per kg and 1150 Wh per L, 10C power capability, an extremely fast charge rate of 0%-80% state of charge in approximately six minutes, the ability to operate in a wide temperature range of minus 30 degrees Celsius up to 55 degrees Celsius, and safety design features that enable us to pass the United States' military's benchmark nail penetration test. Each of these performance parameters is critically important to real-world electrical mobility applications. Not only do our batteries enable certain aircraft and vehicles to maximize performance, but they enable our customers to achieve their economic targets as well. In addition, Amprius has developed a 500 Wh per kg and 1300 Wh per L battery platform that was validated by a third-party.

[Kang Sun, CEO at Amprius Technologies]

It is our belief that there are no other commercial batteries on the market that can perform at these levels today. In the first quarter, Amprius continued to demonstrate technological innovation and business growth. We introduced the new cell chemistries, developed the 370 Wh per kg high-power pouch cells, and the 6300 mAh cylindrical cells. We shipped batteries to over 100 customers. Innovative technologies and breakthrough product performance are the foundation of Amprius' business. Following the launch of our SiCore product platform in January of 2024, we introduced a series of new batteries and expanded our portfolio. Today, Amprius has over a dozen SKUs for various customer applications. Two of the new batteries we introduced this quarter have attracted overwhelming attention and strong interest from the market.

[Kang Sun, CEO at Amprius Technologies]

Amprius' high-energy and high-power cell with 370 Wh per kg energy density and 15C discharge rate sets a new performance record and standard in the lithium-ion battery industry and provides a powerful solution to the electrical mobility market, where both endurance and rapid energy delivery are important. We have been shipping this battery for evaluation to customers such as Teledyne FLIR since January. In March, we also introduced our high-energy density 21700 cylindrical cell with 6300 mAh capacity. This battery provides a 25% energy boost over the cells our customers are currently using. We have already shipped this product to a Fortune 500 company in the light electrical vehicle market for their evaluation. The drop-in compatibility of this cell format with our customers' product designs allows manufacturers to boost product performance without costly redesigns.

[Kang Sun, CEO at Amprius Technologies]

This cell was recently voted Best in Show at the 2025 International Battery Seminar in March. This distinction marks the 3rd year in a row that one of Amprius' products has won a major award at the International Battery Seminar. Commercially, what really separates Amprius from the competition in the emerging lithium-ion battery technology space is that we are not just producing battery samples in the lab. Instead, Amprius has been manufacturing high-performance silicon anode batteries at scale. The Amprius batteries with high energy, high power, long cycle life, and safety features are commercially available today. Our new company website, amprius.com, provides more information about Amprius' product technologies and applications. It is a great source for our customers, partners, investors, and shareholders. We are actively leveraging this new resource to make inroads with new customers across market segments. Q1 is another quarter with multiple commercial wins at Amprius.

[Kang Sun, CEO at Amprius Technologies]

Both new and returning customers continued to recognize our best-in-class product performance and place orders with us in the first quarter. We shipped to 102 customers, with 46 of those being new to Amprius' platform. The breakthrough performance and the large production capacity of Amprius' SiCore battery enabled us to attract customers that drive revenue growth. We generated revenue of $11.3 million in Q1, a 6% increase from the fourth quarter of last year and up to 383% from the same period last year. This strong growth was primarily driven by a greater than 600% increase in SiCore shipments since we began selling the commercial product at the beginning of last year. SiCore's mass production capability has allowed us to become cost competitive with traditional battery manufacturers who are maintaining our firm technology advantages opening the doors to new customers and enabling large volume to current customers.

[Kang Sun, CEO at Amprius Technologies]

In Q1, 83% of our revenue came from outside of the United States on a ship-to basis. This is an increase from 65% in the prior year period, demonstrating the expansion of our customer base worldwide. This customer diversification has also allowed us to grow despite the general headwinds and uncertainty created by the current tariff policies domestically and internationally. During the quarter, we also announced a $15 million purchase order from unmanned aerial systems, OEM. This order was the result of the nine-month non-testing cycle that resulted in Amprius' battery being designed into the manufacturer's fixed-wing UAS platform. We remain on track to ship these cells in the second half of the year to fulfill the customer demands. Orders like these demonstrate our ability to work with customers throughout the design and the qualification process and convert them into volume orders over time.

[Kang Sun, CEO at Amprius Technologies]

As we previously discussed, this process generally takes anywhere between 9-18 months for aviation customers. However, that time can be cut down significantly for customers in the light electrical vehicle sector, which is already running at scale. We have made strong progress in penetrating the light electrical vehicle market, and approximately 25% of our revenue in the first quarter came from that segment. We expect the shorter design cycles for this mature market, combined with our drop-in replacement batteries, will help us succeed in gaining additional market shares in this growing market. In total, we added $34.5 million in new customer purchase orders to our backlog in the first quarter, giving us additional visibility into our growth for the remainder of 2025. In 2024, Amprius developed the gigawatt-hour scale SiCore contract manufacturing capability that enabled us to fulfill both our backlog and the new orders.

[Kang Sun, CEO at Amprius Technologies]

The availability of a large-scale manufacturing facility also helped us to attract volume customers and the competing production cost. In addition to the capacity available to us with our SiCore product through our partners, we have completed our hardware retrofit at our Fremont facility for our SiMaxx product. We are now focused on optimizing the manufacturing process to support our customers that require the 500 Wh per kilo SiMaxx product today. This includes our long-time customer, AALTO/Airbus, and our partner, AeroVironment, for the X-Time Prime U.S. Army grant program. Setting up the current quarter, we entered Q2 with significant operating momentum. We have introduced new products with breakthrough performance, the 450 Wh per kilo SiCore cell. Since we debuted our SiCore platform, we have been actively working to increase our portfolio's performance.

[Kang Sun, CEO at Amprius Technologies]

The 450 Wh per kilo cell is a testament to the research and the development work we have done to maximize energy density. Offering 400 Wh per kilo and 900 Wh per L, this new cell delivers up to 80% more energy than conventional lithium-ion battery cells using graphite anodes, making it an ideal cell for aviation and electrical mobility applications. We believe that this new product, combined with the products that are already in volume production, will be the growth engine of our revenue in 2025. Amprius has several layers of defense for trade conflicts and tariffs. First, we believe that we deliver the highest performing cells on the market today at a competitive cost. For many of our customers, it is not a question of choosing us over a competitor. We are the only solution on the market that can meet their technical and economic needs.

[Kang Sun, CEO at Amprius Technologies]

Second, over 80% of our revenue last quarter was out of the scope for current U.S. import tariffs because our customers were located outside of the country. For the product sold to U.S. customers, we are working along the supply chain to achieve the economic solutions for all parties. In addition, we have diversified our manufacturing globally to insulate us from the potential impact of the tariffs. Like every business in today's marketplace, we are monitoring the latest policy decisions from the U.S. government and others around the globe. Put together, despite the lingering uncertainty, we remain confident in our expectations for growth for the full year based on the information we have today, as well as the proactive steps we have taken to mitigate the potential impacts.

[Kang Sun, CEO at Amprius Technologies]

The important recent business highlight at Amprius is our recent announcement that Tom Stepien has joined us as the President of Amprius Technologies. Tom brings over 35 years of leadership experience to Amprius and has a rare combination of both technical expertise and market leadership at innovative technology companies. As we expand our global footprint, Tom's decades of experience in growing energy and manufacturing businesses will be instrumental in guiding Amprius through the next phase of growth. With that, I will now turn the call over to Sandra to review our financial results.

[Sandra Wallach, CFO at Amprius Technologies]

Thank you, Kang. I would now like to spend a few minutes covering some key financial updates. As a reminder, our detailed financials can be found in our shareholder letter. We ended the first quarter with $11.3 million in total revenue.

[Sandra Wallach, CFO at Amprius Technologies]

As we have previously discussed, our total revenue is a combination of our main revenue streams, product revenue, as well as development services and grant revenue. This quarter, $11 million came from our product revenue, representing a $0.7 million or 6% increase sequentially. Product revenue in Q1 2024 was just $2.3 million, marking a 370% or $8.6 million year-over-year increase. Our development services and grant revenue totaled $0.3 million this quarter, which was consistent with $0.3 million in Q4 2024 and up from zero year-over-year. As we've discussed in the past, development services and grant revenue from large development programs are non-recurring in nature, leading to greater fluctuations depending on the comparison period. The overall increase in revenue this quarter was primarily driven by the addition of new customers. As Kang mentioned, we shipped to 102 customers in the first quarter.

[Sandra Wallach, CFO at Amprius Technologies]

Of these customers, only three accounted for greater than 10% of revenue, consistent with three customers in both the first and the fourth quarters of 2024. Going forward, we plan to continue adding to our customer mix to diversify our revenue streams and provide more reliable product shipments as we get to a position of scale. Now moving to our profitability metrics, gross margin was negative 21% for the quarter compared to negative 21% in Q4 2024 and negative 190% in the prior year period. As a reminder, we see significant gross margin variation as our product and services revenue mix fluctuates. Gross margins in 2024 were also impacted by pre-construction planning costs related to the Colorado facility, which were completed in October of 2024.

[Sandra Wallach, CFO at Amprius Technologies]

Now moving on to our operating expense management, our operating expenses for the first quarter were $7.3 million, a decrease of $2.2 million or 23% compared to Q4 2024, and an increase of $1.4 million or 24% from the prior year period. OpEx decreases from Q4 to Q1 were driven by the non-recurring loss on retirement of property, plant, and equipment discussed in our Q4 and full-year earnings of $1.9 million. Year-over-year, the increase in OpEx was driven by increased investment in sales and the reallocation of R&D from cost of goods sold as development services agreements run off. Our GAAP net loss for the first quarter was $9.4 million, or negative $0.08 per share, with 117.9 million weighted average number of shares outstanding. In Q4 2024, our net loss was $11.4 million, or negative $0.10 per share, with 109.8 million weighted average number of shares outstanding.

[Sandra Wallach, CFO at Amprius Technologies]

Q1 2024, net loss was $9.9 million, or negative $0.11 per share, with 90 million weighted average number of shares outstanding. As of March 31st, 2025, there were 95 full-time employees, down from 99 at the end of the fourth quarter, with those employees primarily based in our Fremont, California location. Our share-based compensation for the first quarter was $1.8 million compared to $2.4 million in Q4 and $1.2 million in the prior year period. The sequential decrease is primarily attributable to $0.7 million in the non-recurring grant of fully vested shares by Amprius Technologies for key employees and service providers that occurred in the fourth quarter. As of March 31st, 2025, we had 120.5 million shares outstanding, which was up 3.6 million from the prior quarter.

[Sandra Wallach, CFO at Amprius Technologies]

That change includes approximately 1 million shares issued from option exercises and RSU vesting, and 2.6 million shares issued from our ATM reserve. Now turning to the balance sheet, we exited the first quarter with $48.4 million in net cash and no debt. Key drivers for cash in the quarter included $14.1 million used in operating cash flow, which was slightly higher than our projected run rate of approximately $2.5million-$3 million monthly, excluding transaction-related cost. The main cause of the variance this quarter is related to the change in working capital accounts, specifically late quarter billings caught up in accounts receivable at the end of the quarter. $0.9 million in investment related to the Fremont, California facility. We also had $8.5 million in cash inflow from the issuance of common stock under the at-market sales agreement. We still have $57.8 million left on the facility.

[Sandra Wallach, CFO at Amprius Technologies]

Considering our business achievements and ongoing projects, we believe we are efficiently using capital to drive Amprius forward. Before I turn the call back over to Kang, I would like to take a moment to discuss our CapEx outlook for the remainder of 2025. We expect to move to a steady state of quarterly investment in normal operating items, with the hardware upgrade behind us for Fremont. At this time, there are no plans to move forward with the Colorado facility. The designs for this project are effectively complete, and we are continuing to monitor the larger industry dynamics associated with building a factory in the United States. Changes in demand, supply, battery cost structure, government incentives, trade tariffs, and other considerations, including the timing and availability of funding, will influence our decisions on the next step and timing.

[Sandra Wallach, CFO at Amprius Technologies]

We have secured adequate capacity for the foreseeable future through our contract manufacturing network and plan to further expand that in 2025 without deploying our capital. That concludes my financial discussion, and I will now pass the call back to Kang.

[Kang Sun, CEO at Amprius Technologies]

Thanks, Sandra. As we look ahead, our strategy at Amprius remains unchanged. The company is focusing on technology innovation, new product introduction, quality manufacturing, customer engagement, and the revenue growth. We realize that our success depends on our ability to execute our vision. We expect to release new batteries on our product roadmap that will further our lead in the battery space. This includes new products from our SiCore platform and the commercial availability of SiMaxx 500 Wh per kg product. We will continue to build our book of customers with 235 customers in 2024 and the addition of 46 new customers in the first quarter.

[Kang Sun, CEO at Amprius Technologies]

We are excited about the opportunity in front of us. We expect to convert this engagement into customer purchase orders as quickly as we can. We are strengthening and expanding our manufacturing capability and the capacities to better align geographically with our customers worldwide. We believe the opportunity ahead of Amprius is tremendous. We believe we are well positioned for continued success with our industry-leading silicon anode batteries, backed by gigawatt-hour scale manufacturing capabilities through our capital-light contract manufacturing network. Our extended customer engagement is evident in the hundreds of customers we shipped to in 2024, including both new business and the repeat orders from our market customers. From a financial perspective, we are in excellent shape with adequate cash reserve at a low burn rate, no debt, and our existing at-the-market sales agreement provides additional flexibility.

[Kang Sun, CEO at Amprius Technologies]

These co-pillars will help us continue to support a strong and growing business throughout the rest of the year and beyond. Over the next few months, we'll be attending several industrial and financial conferences. We hope to see you there. Thank you for your continued support of Amprius Technologies. With that, I will turn it back to the operator for Q&A.

[Operator]

Thank you. We'll now be conducting a question-and-answer session. If you would like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate that your line is in the question queue. You may press star two to remove yourself from the queue. For participants using speaker equipment, it may be necessary to pick up the handset before pressing the star keys. One moment while we poll for questions. Our first question comes from Colin Rusch with Oppenheimer.

[Operator]

Please proceed with your question.

[Colin Rusch, Head of Sustainable Growth and Resource Optimization at Oppenheimer]

Thanks so much, guys. The order number in the quarter is pretty impressive to have a three-to-one book to bill. Having the relatively high volume of incremental customers that you guys are talking about here for several quarters, I'm curious about how that testing activity is going with those customers and how quickly some of that might translate into incremental orders here for you guys as you get through the balance of the year.

[Kang Sun, CEO at Amprius Technologies]

Yeah, Colin, the customer contract that you have mentioned, I believe we had three last customer contracts in addition to two development contracts. Those contracts will be complete before the end of the year. Some contracts will be complete in Q2.

[Colin Rusch, Head of Sustainable Growth and Resource Optimization at Oppenheimer]

Excellent. As you guys think about the diversity of those customers, how important is it to have some non-China manufacturing for the SiCore product line?

[Colin Rusch, Head of Sustainable Growth and Resource Optimization at Oppenheimer]

Is that something that we could see get ramped up here in 2025, or is that something that's a little bit longer-term project for you guys?

[Kang Sun, CEO at Amprius Technologies]

Yeah, we'll be in 2025. Very soon, you will learn from us. We have an additional contract manufacturing facility outside of China.

[Colin Rusch, Head of Sustainable Growth and Resource Optimization at Oppenheimer]

Excellent. And just the final one for me. As you think about scaling the organization, you've gotten an awful lot of leverage out of existing OpEx. I'm just curious, with Tom coming on and increasing sales activity, what other sort of augmentation are you going to need to do in terms of team growth to support some of the trajectory that looks like it's possible here for the company?

[Kang Sun, CEO at Amprius Technologies]

Yeah, Colin, three areas. First one is R&D because this is the foundation of our business. You can see that Amprius has a visible leadership in this industry.

[Kang Sun, CEO at Amprius Technologies]

That is where we will strengthen our R&D capability. The second part is contract manufacturing capability. We will have a stronger team built up to manage those contract manufacturer partnerships. The third one is sales. Every quarter, you will see our sales team is expanding.

[Colin Rusch, Head of Sustainable Growth and Resource Optimization at Oppenheimer]

Excellent. Thanks so much, you guys.

[Operator]

Thank you. Our next question comes from Jed Dorsheimer with William Blair. Please proceed with your question.

[Mark Shooter, Senior Associate at William Blair]

Hi, Tom. You have Mark Schooter on for Jed Dorsheimer. 83% of revenue is outside of the U.S., so that is very helpful for the given tariff situation. How do you see this progressing through the year, and has the tariff situation changed your strategy on who are the new customers that you are going to be sampling with of the new 43? Will that change anything going forward throughout the year?

[Kang Sun, CEO at Amprius Technologies]

First, Mark, the tariff is not our primary concern because we have a very, very competitive cost base. In addition, we have a global reach to our customers, so we do not see a dramatic increase in our domestic customer base.

[Mark Shooter, Senior Associate at William Blair]

Okay, that is very helpful. Thank you. Congrats on the success of the SiCore product. Speaking to that, have you seen any competitive products from the giants in China, like CATL or BYD, considering your manufacturing in their backyard and if they have access to similar advanced silicon materials? Without giving away the secrets, what does Amprius have that these big competitors are missing that puts your performance so far ahead?

[Kang Sun, CEO at Amprius Technologies]

Mark, I think the major difference is market participation. All those large incumbent manufacturing companies focus on the EV segment and the consumer electronics segment at this moment.

[Kang Sun, CEO at Amprius Technologies]

Their cell chemistry, their cell design are quite different from Amprius. Now, Amprius today, we have the most complete silicon anode technology portfolio. We have silicon monoxide, silicon carbon, silicon nanowire, you name it. We're even working on the more advanced silicon anode today. I think the market will focus on not the market concentration of those incumbents. That's the number one. Number two, we do have a very unique cell chemistry. I don't mean we cannot develop it someday, but at this moment, we're certainly in the leading position.

[Mark Shooter, Senior Associate at William Blair]

That's very helpful. Thank you.

[Operator]

Thank you. Our next question comes from Chip Moore with Roth MKM. Please proceed with your question.

[Chip Moore, Managing Director and Senior Research Analyst at Roth MKM]

Thanks for taking the question. Hey, everybody, maybe just to follow up on that last one, just more technical.

[Chip Moore, Managing Director and Senior Research Analyst at Roth MKM]

Can you talk about if you're incorporating and blending any third-party silicon anode materials into some of the newer products and any vendors you might be using?

[Kang Sun, CEO at Amprius Technologies]

Yeah, we discussed earlier. We use Berzelius silicon anode as one of our components in our cell chemistry. We have explored and tested other people's silicon material, but our primary source still comes from Berzelius.

[Chip Moore, Managing Director and Senior Research Analyst at Roth MKM]

Gotcha. Thanks, Kang. Maybe just an update on contract manufacturing partners ex-China. I know you've been making the rounds in, I think, Korea and Europe. Just any update there and how to think about timelines?

[Kang Sun, CEO at Amprius Technologies]

Yeah, timeline. Very soon, we will have contract manufacturer partners outside of China.

[Chip Moore, Managing Director and Senior Research Analyst at Roth MKM]

Okay, we'll stay tuned. Thanks, Kang.

[Operator]

Thank you. Our next question comes from Amit Dayal with H.C. Wainwright. Please proceed with your question.

[Amit Dayal, Managing Director and Senior Technology Analyst at H.C. Wainwright]

Thank you. Good afternoon, everyone. Thank you for taking my questions.

[Amit Dayal, Managing Director and Senior Technology Analyst at H.C. Wainwright]

With respect to the backlog, it grew nicely in the first quarter. Does this set you up for sequential revenue improvements through 2025?

[Kang Sun, CEO at Amprius Technologies]

I would expect so. We have a very strong pipeline as you see, and our customer qualifications, some of those reached the advanced stage. We anticipate the revenue growth.

[Amit Dayal, Managing Director and Senior Technology Analyst at H.C. Wainwright]

Understood. Thank you. With respect to some of the new offerings you are planning on launching over the next few quarters, what is the risk of maybe some cannibalization taking place with the existing offerings you already have in the market?

[Kang Sun, CEO at Amprius Technologies]

Yes, of course. Yeah. We always think we need kill to tell our older technologies ourselves instead of others. This is the biggest progress we have made in the last few months to deliver new cell chemistry, new performance batteries, higher performance batteries.

[Kang Sun, CEO at Amprius Technologies]

It's going to have some influence on our existing product. That's what our customers like to see. That's going to enlarge the gap between us and the competition.

[Amit Dayal, Managing Director and Senior Technology Analyst at H.C. Wainwright]

The reason I was asking that, Kang, is because maybe the batteries need to be designed in. As you keep launching some of these new offerings and the customers might prefer these new offerings, do you need to start that process all over again to be designed into those offerings?

[Kang Sun, CEO at Amprius Technologies]

That's not going to happen because those new products certainly aim at a new application or upgrade their device performance. They're not going to use the new product to put in the older device to start over again.

[Amit Dayal, Managing Director and Senior Technology Analyst at H.C. Wainwright]

Okay. Understood. Yeah, that's all I have. I'll follow up offline. Thank you so much.

[Operator]

Thank you.

[Operator]

Once again, if you'd like to ask a question, please press star one on your telephone keypad. That is star one. Our next question comes from Derek Soderberg with Cantor Fitzgerald. Please proceed with your question.

[Derek Soderberg, Director at Cantor Fitzgerald]

Yeah. Hey, Kang and Sandra. Thanks for taking the questions. Sandra, I think you said last quarter that backlog was $16 million or $17 million. Looks like you shipped $11 million in product this quarter, and then you added $34.5 million to backlog. Does that mean backlog today is roughly $40 million? Am I thinking about that right?

[Sandra Wallach, CFO at Amprius Technologies]

Let's see. Let me get you the number because we just filed the Q. The remaining performance obligations are, I think it's $37.8 million, including government grant. Yeah.

[Derek Soderberg, Director at Cantor Fitzgerald]

Perfect. No, that's helpful. Just wanted to clarify. And then a couple more on the Fortune 500 company testing the 21700 cylindrical.

[Derek Soderberg, Director at Cantor Fitzgerald]

You are delivering samples to that customer for a light electric vehicle. Can you sort of share with us the expected timeline to sign a large purchase order with that customer? How long is the qualification process? Can you provide some color on that timeline?

[Kang Sun, CEO at Amprius Technologies]

This is a leading supplier in this industry. We anticipate the volume orders will come in sometime in the later part of 2026.

[Derek Soderberg, Director at Cantor Fitzgerald]

Got it. That's helpful. Sandra, back to you. As you are releasing new battery platforms, the technology continues to improve. Sandra, I think the SiCore gross margin is sort of in the low teens, roughly. Where do you see margins heading towards as you commercialize some of these higher tech cells, just such as the 21700, which I believe is the SiCore platform?

[Derek Soderberg, Director at Cantor Fitzgerald]

Can you sort of talk about the mix shift, how that's going to help margin, and how much you think pricing can help margin?

[Sandra Wallach, CFO at Amprius Technologies]

That's a great question. We've shared that the SiCore product has been gross margin and cash flow positive from day one, and that's how we've made the step function improvement in gross margins. We're still running a very small footprint for SiMaxx. We believe our growth engine in the near term is going to be SiCore, and that's just going to continue to drive gross margins to be more positive over time.

[Derek Soderberg, Director at Cantor Fitzgerald]

Is that that 21700, is that the SiCore platform?

[Sandra Wallach, CFO at Amprius Technologies]

Yes. Yep.

[Derek Soderberg, Director at Cantor Fitzgerald]

Got it. Sandra, I think you commented on some of the SiMaxx investments on the scale-up, and it looks like the designs are complete for the Colorado facility.

[Derek Soderberg, Director at Cantor Fitzgerald]

What sort of growth CapEx do you have planned for the remainder of the year?

[Sandra Wallach, CFO at Amprius Technologies]

Very little. We're pivoting into really just run-the-business mode.

[Derek Soderberg, Director at Cantor Fitzgerald]

Got it.

[Sandra Wallach, CFO at Amprius Technologies]

So normal replacements and maintenance. Yep.

[Derek Soderberg, Director at Cantor Fitzgerald]

Perfect. Really appreciate it. Thanks.
