[Kang Sun, CEO at Amprius Technologies]

Welcome, everyone, and thank you for joining us this afternoon. On today's call, I will report our accomplishments from the first quarter, while also highlighting some of the upcoming milestones we are expecting for this year. Our CFO, Sandra Wallach, will then discuss our financial results for the period. After that, 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 the company.

[Kang Sun, CEO at Amprius Technologies]

As a reminder, here at Amprius, we develop, manufacture, and market high-energy density and high-power density batteries with applications across all segments of the electrical mobility, including the aviation and the EV industries. Across our battery portfolio, we offer unmatched performance, including batteries capable of a specific energy density of 450 Wh/kg and a volumetric energy density of 1,150 Wh/L.

[Kang Sun, CEO at Amprius Technologies]

High power capability: the extreme fast charge rates of 0%-80% state of the charge in approximately 6 minutes. The ability to operate in a wide temperature range of -30 degrees Celsius up to 55 degrees Celsius. The safety design features that enable us to pass the U.S. Military's benchmark nail penetration test. Late last year, we achieved third-party validation of our latest 500 Wh/kg, 1,300 Wh/L battery platform, which we expect will be ready for commercial shipment later in 2024. Each of these performance parameters is critically important to electrical mobility applications. Not only do our batteries enable certain aircraft and vehicles to function, but they enable our customers to achieve their economic targets as well. It's our belief that there are no other commercial batteries on the market that can perform at this level today. Amprius is a silicon-anode battery technology pioneer.

[Kang Sun, CEO at Amprius Technologies]

With over a decade of development experience, a strong patent portfolio of over 80 issued patents and patent applications, and a long track record of commercial shipments and customer successes. Turning now to a review of our first quarter. To start 2024, in addition to driving industry-leading performance with our battery technology, we took critical steps to drive our scale-up efforts and increase our output to meet the growing demand for our solutions. In January, as part of this continued push to make our products available to the electrical mobility space, we launched our all-new SiCore product family to go along with our existing silicon nanowire platform, now called SiMaxx.

[Kang Sun, CEO at Amprius Technologies]

Complementary to SiMaxx, which is Amprius highest energy density performance battery offering, the SiCore platform services applications that demand both high energy density and longer SiCore life, offering up to 400 Wh/kg and as many as 1,200 SiCore at a full depth of discharge. The SiCore product family also has additional form factor flexibility, capable of both pouch and cylindrical cell form factors. This enables their utilization across a broader range of applications, such as e-bikes and other micro-mobility market segments.

[Kang Sun, CEO at Amprius Technologies]

In addition to having another product platform available for Amprius customers, the introduction of a SiCore battery accelerates our revenue growth without additional capital investment and serves our customer without delay. To produce SiCore batteries, we take advantage of existing available lithium-ion battery production capacity in the industry and have toll manufacturers as a bridge between now and the operation of our own large-scale manufacturing facility.

[Kang Sun, CEO at Amprius Technologies]

These toll manufacturing agreements provide us with hundreds of megawatt-hours of SiCore capacity today. Overall, SiMaxx and SiCore are the culmination of years of work in the silicon-anode space and are just the beginning of our vision here at Amprius to transform electrical mobility. We look forward to manufacturing both SiMaxx and SiCore at our Brighton, Colorado, facility in the future. So far, 2024 has been a huge success commercially for Amprius. In Q1, we doubled the number of customers we shipped to over Q4 2023, shipping to 82 customers, up from 41. 52 of these shipments were to new customers across the electrical mobility sector, complementing our strong, repeat customer base that includes AALTO, Airbus, Teledyne FLIR, the U.S. Army, Kraus Hamdani, and BAE Systems. The SiCore platform and manufacturing capacity is a primary drivers of our ability to meet this market demand.

[Kang Sun, CEO at Amprius Technologies]

In the first quarter, we shipped SiCore products to 76 customers. As we further build out our book of customers for SiCore, we are confident that we will be able to continue to meet the strong demand for our batteries while our SiMaxx production approaches large-scale capacity. As customer demand for Amprius batteries is accelerating, expanding production capacity is our priority. In Q1, we continued to make significant progress in ramping up our production in Fremont, California. Most recently, we completed the qualification process for our Centrotherm machine, which is used in the silicon-anode fabrication process. We remain on track to achieve 2 MWh production in Fremont by the end of the year. We are also implementing SiMaxx cathode production in-house to streamline our manufacturing process. We plan to have this capacity up and running in Fremont later this year.

[Kang Sun, CEO at Amprius Technologies]

We have continued to make important progress at our large-scale manufacturing site in Brighton, Colorado, as well. We currently have completed 30% of the construction design drawings and specifications for the facility and have taken several regulatory steps forward, including submitting our site plan and advancing all other regulatory plans and applications for the facility. As an additional step, and in response to the market's strong reaction to our SiCore platform, we have updated our plans for the Brighton facility to redesign our initial production line to be SiCore-focused. We will continue to produce SiMaxx out of Fremont until a second line begins production in Brighton. Looking ahead, we have already carried our momentum from the beginning of the year into the second quarter across several of our initiatives.

[Kang Sun, CEO at Amprius Technologies]

First, we recently signed our first long-term manufacturing agreement with one of our toll manufacturing partners to confirm our collaboration and strategic alignment. This new agreement establishes overall engagement and moves us from operating transitionally to a partnership framework. Second, we have extended our partnership with several customers, including multiple purchase orders from AALTO, Airbus for our SiMaxx 450 Wh/kg high-energy density cell. They are continuing to use these cells in their project Zephyr, with SiMaxx supplying the necessary power and endurance for their stratospheric fly operation. We have also received the first production order for the U.S. Army safe cells, and we expect to deliver them later this year. This is the first order we have received after the successful completion of the development contract that we discussed during our last call.

[Kang Sun, CEO at Amprius Technologies]

Third, we have signed several new strategic partnerships in the second quarter, most notably with AALTO and Stafl Systems. Amprius will soon provide SiCore cells to both partners, ensuring maximum power and reliability for AALTO's mission-critical operation and serving as Stafl Systems' preferred battery cell supplier. We look forward to partnering with both teams as they work on shaping the future of electrical mobility. I believe that these collaborations can provide Amprius with an increase in sales, expanding market reach, and a greater market share in the high-performance battery market segment.

[Kang Sun, CEO at Amprius Technologies]

Together, these high-profile customers and strategic partnerships have helped strengthen Amprius' traction in our industry. Just a few weeks ago, in response to the growing global awareness of our battery, Amprius hosted the first Taiwan Battery Forum, where over 100 attendees from the industry-leading companies and institutions learned about Amprius' breakthrough silicon-anode battery technologies and partnership opportunities.

[Kang Sun, CEO at Amprius Technologies]

Also in April, Amprius was honored with the Overall Battery Company of the Year award at the Cleantech Breakthrough. This comes on the heels of Amprius' nomination to the Fast Company Annual List of the World's Most Innovative Companies, another point of recognition for our business. While we have long known that our products are yet to be matched at the commercial level, we are proud that the industry is taking notice as well. It's clear that our recent customer expansion and the new industry recognition signal a strong start to 2024 for Amprius. We are working hard to expand our production capacity to meet our sizable demand, and we are confident in the path forward for Amprius. With that, we will turn the call over to our CFO, Sandra Wallach, to review our financial results for the quarter. Sandra.

[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 finished the first quarter with $2.3 million in total revenue. As we've previously discussed, our total revenue is the combination of two main revenue streams: product revenue and development services and grant revenue. This quarter, all $2.3 million of our revenue came from our product revenue, representing a 397% increase from the prior year period and a 147% sequential increase. These increases were largely driven by shipments to 82 customers in the quarter, a significant increase for Amprius. Although our product revenue remains largely driven by customer purchase orders that can arrive at uneven times throughout the year, we have shown consistent new customer growth and diversification in recent quarters.

[Sandra Wallach, CFO at Amprius Technologies]

Also, of these customers, only three customers represented greater than 10% of revenue, a testament to our diverse customer set. As we've discussed in prior quarters, our development services revenue comes largely from large development programs that are non-recurring in nature. Moving to our profitability metrics, our gross margin was negative 190% for the quarter, compared to negative 518% in the prior year period and negative 98% in Q4 of 2023.

[Sandra Wallach, CFO at Amprius Technologies]

As a reminder, we see significant gross margin variation as our product and services revenue mix fluctuates. Also, we anticipated that factory startup costs would ramp up as we start Colorado design and pre-construction and still expect this to be the case through at least 2024. Longer term, we're confident that our GAAP gross margin will begin to normalize as we approach our capacity expansion goals. Now on to our operating expense management.

[Sandra Wallach, CFO at Amprius Technologies]

Our operating expenses for the first quarter were $5.9 million, a 6% decrease from the prior year period and flat quarter-over-quarter. This decrease is primarily attributable to a decrease in G&A costs that were offset by investment in R&D and sales. Our GAAP net loss for the first quarter was $9.9 million, or a net loss of $0.11 per share, with 90 million weighted average number of shares outstanding, compared to a net loss of $0.11 per share with 84.6 million weighted average number of shares outstanding in the prior year period. Also, as of March 31, 2024, there were 81 full-time employees, up from 80 in the fourth quarter and 65 in the prior year period, with those employees primarily based in our Fremont, California, location.

[Sandra Wallach, CFO at Amprius Technologies]

Our share-based compensation for the first quarter was $1.2 million, compared to $1.1 million in Q4 of 2023 and $0.7 million in the prior year period. As of March 31, 2024, we have 92.3 million shares outstanding. Now, turning to the balance sheet, we exited the first quarter with $39 million in cash and no debt. Key drivers of our cash activity for the quarter were: $9.8 million used in operating cash flow, $3.1 million used to continue our buildout of our expanded 2 MW production line in Fremont, $0.8 million used for progress payments to secure our production slots for mechanical, electrical, and plumbing equipment, and $8.2 million of cash inflow added primarily through the usage of our ATM. Considering our business achievements and ongoing projects, we believe we are efficiently using capital to drive Amprius forward.

[Sandra Wallach, CFO at Amprius Technologies]

Before I turn the call back over to Kang, I would like to take a moment to discuss our outlook for the remainder of the year. We expect to spend another $1 million-$2 million on equipment to support the 2 MW line in Fremont. This includes the necessary tools to have our cathode line up and running by the fourth quarter of this year. As Kang mentioned, we're also finalizing the design work for our Colorado facility. We expect to publicly communicate a construction cost forecast once the plan is finished. As part of our ongoing strategic planning efforts, we filed a shelf registration on Form S3 back in October of 2023, and once effective, established a new ATM facility for $100 million.

[Sandra Wallach, CFO at Amprius Technologies]

Subsequent to March 31, 2024, and through May 3, 2024, we have raised gross proceeds of about $2.1 million through the sale of approximately 1 million shares under the ATM facility. To support our strategic plan, we are pursuing additional funding through multiple vehicles, including equity issuances such as warrant exercises and sales under our ATM, and non-dilutive sources such as grants, loans, and incentives. With that, I will conclude the financial discussion and pass the call back to Kang.

[Kang Sun, CEO at Amprius Technologies]

Thanks, Sandra. I would like to re-emphasize a few key points before closing. First, Amprius silicon anode technology continues to demonstrate unmatched performance in our industry. Amprius batteries command a firm lead with their combination of safety, energy, power, charging time, and temperature performance. They are uniquely positioned for the electrical mobility market.

[Kang Sun, CEO at Amprius Technologies]

Second, Amprius batteries are commercially available today. Our breakthrough technologies are validated by over 80 customer orders. This quarter, we doubled our number of customers who received the shipments. Not only did we have our normal repeat customers, but 52 were new customers, a testament to our robust demand pipeline. We look forward to further building out our customer book in the coming quarters. Third, we are scaling our manufacturing capacity through building our own production capacities and partnering with toll manufacturing partners.

[Kang Sun, CEO at Amprius Technologies]

With our ramp underway in Fremont, our design process moving forward in Brighton, and signing the partnerships with additional toll manufacturing partners in place, we remain on track to expand production capacities to fulfill market demand. Finally, we are looking forward to several exciting upcoming milestones over the rest of the year. We expect to fully optimize our SiMaxx mass production process and ramp up production to a 2 MWh run rate exiting the year at our Fremont facility.

[Kang Sun, CEO at Amprius Technologies]

This will represent a tenfold increase in our production levels that we had exiting 2023 and give us additional available products for the strategic customers. We look forward to taking advantage of the hundreds of MWh of new SiCore product availability provided by our toll manufacturing agreements to reach more customers and expand our current customer engagements. During the summer, we will deliver the 100 Ah EV form factor cell to the U.S.

[Kang Sun, CEO at Amprius Technologies]

Advanced Battery Consortium (USABC), as a part of our grant program. We are in the process of finalizing the design plans and are excited to begin the construction of our gigawatt-scale facility in Brighton, Colorado. As we always prioritized, we will continue to bring to market new and innovative products that push the boundaries of what is possible for our industry. As part of this, we look forward to commercializing our 500 Wh/kg SiMaxx cells later this year. As we look ahead, our strategy and focus on Amprius remains unchanged. We believe that the opportunity in front of Amprius is tremendous and that our product portfolio positions us to both grow in the aviation market and expand to other industries seeking batteries with leading performance.

[Kang Sun, CEO at Amprius Technologies]

Our addressable markets are growing and durable, including the $1.2 billion conformal wearable battery market by 2030, the $3 billion aviation battery market by 2030, and the $500 billion EV battery market by 2033, all of which are Amprius growth paths in coming years. 2024 is off to a strong start. We look forward to continuing to deliver what we have planned and promised in the year ahead. Thank you for your continued support of Amprius Technologies. With that, I will turn it back to the operator for the Q&A.

[Operator]

Thank you. At this time, we'll open the lines for questions. The company requests that each participant limit their comments to one question and one follow-up. If you would like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. Our first question is from Colin Rusch with Oppenheimer & Company. Please proceed.

[Colin Rusch, Managing Director and Senior Analyst at Oppenheimer & Co]

Thanks so much. Guys, there is an awful lot of new customers. Can you give us a sense of what the diversity is from a geographic standpoint and an application standpoint? You mentioned mobility. I'm just curious if you can give us a sense of who those folks are and what sort of sampling they're doing at this point.

[Kang Sun, CEO at Amprius Technologies]

Yeah, Colin, we have disclosed some customers we can disclose. Our customer coverage is quite broad. Primarily in the United States and Europe, we also have Asian customers. For example, we have customers in India. Our primary battery application for those customers is still in the aviation industry.

[Colin Rusch, Managing Director and Senior Analyst at Oppenheimer & Co]

Excellent. Thanks so much. And then as you move into working with a contract manufacturer, can you talk a little bit about how you anticipate your potential scaling of sales? It seems to me that you guys are in a unique position to grow fairly quickly as you get into the balance of the year from a revenue perspective.

[Kang Sun, CEO at Amprius Technologies]

Yeah. We are strengthening our sales team. With the introduction of a SiCore product, we basically resolved the manufacturing capacity issue for that particular product. We have hundreds of megawatt-hours of capacity behind us, both in cylindrical form and in pouch form. This gave us tremendous support for our customer development effort here. Recently, we just added more individuals to our sales force.

[Colin Rusch, Managing Director and Senior Analyst at Oppenheimer & Co]

Thanks so much. Then in Fremont, just the final one from me, can you talk a little bit about the tool qualification and how that's going? Are the machines, and primarily the key machine working as you anticipated as you go through all the testing processes?

[Kang Sun, CEO at Amprius Technologies]

Yeah. In Fremont, the only machine that matters is the Centrotherm machine which produces the silicon nanowire anode, right? The rest of the equipment are off-the-shelf equipment, just like other people are using in the industry. So recently, the Fremont Centrotherm machine started producing silicon anode for our batteries. So, of course, we still need to adjust the production protocol, perfect the production protocol, make it more efficient. When we say qualification of the machine, we mean the machine can produce quality silicon anode for our batteries.

[Colin Rusch, Managing Director and Senior Analyst at Oppenheimer & Co]

Thanks so much, guys.

[Operator]

Our next question is from Donovan Schafer with Northland Capital Markets. Please proceed.

[Donovan Schafer, Managing Director and Senior Analyst at Northland Capital Markets]

Hey, guys. Thanks for taking the questions. So first, I want to also ask about, with the customer orders, with there being so many, the 82 deliveries to customers. So just to kind of cross the T's and dot the I's, I just want to confirm. So you say 52 of those were to new customers across the electricity or electric mobility sector. Is there any caveat there, or can I just take the 82 minus the 52 to say that you had 30 repeat orders in the quarter? Is that accurate?

[Sandra Wallach, CFO at Amprius Technologies]

Yeah, that's the right math.

[Donovan Schafer, Managing Director and Senior Analyst at Northland Capital Markets]

Okay, great. And then the other part of that is it looks like 76 of the shipments were for SiCore. So I guess that raises the question, do you have some repeat customers where they previously did SiMaxx orders and now they're showing an interest in SiCore? And so I guess they had enough interest in SiMaxx but are also curious to know how this other product potentially works for them. Is that kind of what's going on there?

[Kang Sun, CEO at Amprius Technologies]

I'm sorry. Yeah. We have a customer interest in both products.

[Donovan Schafer, Managing Director and Senior Analyst at Northland Capital Markets]

Some of it's crossing over, it seems like?

[Kang Sun, CEO at Amprius Technologies]

Those products offer, yeah. That's right. Yeah. Yeah.

[Donovan Schafer, Managing Director and Senior Analyst at Northland Capital Markets]

Okay. Okay. And then I saw in the letter to investors that the initial production in Colorado, you switched to that will be for SiCore now instead of SiMaxx. And you say that that's in response to kind of customer interest. But what I'm curious is, can you give us anything more in terms of what are the specific attributes about SiCore versus SiMaxx that's causing that interest? And also, is there a difference in manufacturing costs that's an impact there where one is less expensive to manufacture versus the other?

[Kang Sun, CEO at Amprius Technologies]

Yeah. One of the reasons we have a tremendous interest for SiCore is because we have more SiCore for customers today, right? We have a large production capacity behind us, so we can serve a lot more customers. So the more customers we serve, the more interests come to us. So that's the reason we look at the momentum we build up here. We say, "Hey, we probably need to build the SiCore first because those customers, the better time we finish our factory, we will have from our customers.

[Donovan Schafer, Managing Director and Senior Analyst at Northland Capital Markets]

Okay. I see. So it's the fact that you can have these conversations around SiCore where you've got the tolling arrangements in place already with some manufacturers. So that creates more of an interest with the potential customer because, okay, guys, you're ready to provide volume, and then you might as well bring that manufacturing in-house over time. So then I guess the question there is, when should we start to expect to maybe see that tolling partnership that you've kind of buttoned up with one manufacturer? Do you have any sense around when that could start turning into some kind of a revenue around the SiCore product at a scale, even though it's sort of through tolling?

[Kang Sun, CEO at Amprius Technologies]

Yeah. You can see we have so many customer engagements now, right? So we believe this year, part of those customers will start. Some of those customers are still in the qualification stage. Not every customer gives big orders. But since we have so many customers, we have over 80 customers, and we expect a fraction of those customers will place decent orders this year.

[Donovan Schafer, Managing Director and Senior Analyst at Northland Capital Markets]

Okay. And I guess that makes sense in terms of sequence, that they're going to be incrementally more interested in taking SiCore, qualifying it, and figuring out if they can incorporate that into their offering at scale. But to show that interest and go through that qualification process, once you've validated or had handshakes and contracts and so forth signed with people so that you can back it up and say, "Okay, once you place an order, we're ready to go." Okay. Sorry, just thinking that through out loud. I'll take the rest of my questions offline. Thank you, guys.

[Kang Sun, CEO at Amprius Technologies]

Thanks.

[Operator]

Our next question is from Jed Dorsheimer with William Blair. Please proceed.

[Mark Shooter, Equity Research Associate at William Blair]

Hi, everybody. This is Mark Shooter on for Jed Dorsheimer. Tom, question on the 76 customers. Say they all come to fruition, and I know you have hundreds of megawatts in the toll coaters, but is there a scenario in which you'll have to restrict allocation to a certain number of customers?

[Kang Sun, CEO at Amprius Technologies]

Yeah. Mark, we have a tremendous capacity behind us for SiCore. For SiCore customers, I would say in 2024, maybe even 2025, we should not have supply issues.

[Mark Shooter, Equity Research Associate at William Blair]

Understood. Okay. Do you see any of those potential customers, is there any restriction on converting to PO based on where the material is coming from? I'm thinking, "Okay, I'd like to place a PO with you, but I'd rather wait for U.S. domestic production." Is that a factor at all in your conversation?

[Kang Sun, CEO at Amprius Technologies]

Yeah. The customer engaged. They shouldn't have that problem. The customer who has the customers who have concerns would not engage with us for toll manufacturing model.

[Mark Shooter, Equity Research Associate at William Blair]

Understood. Okay. Thank you. And lastly here, congrats on the award with the military. Can you give any color on the unit volumes we should be expecting or ASPs or margin? Any color on how we should be modeling that?

[Kang Sun, CEO at Amprius Technologies]

Yeah. Sandra, let you address this.

[Sandra Wallach, CFO at Amprius Technologies]

That is a larger order that is scheduled to go out this year, but we haven't given guidance on pricing and margins on that.

[Mark Shooter, Equity Research Associate at William Blair]

Okay. Understood. Thank you.

[Operator]

Our next question is from Chris Souther with B. Riley Securities. Please proceed.

[Chris Souther, Research Analyst at B. Riley Securities]

Hey, guys. Thanks for taking my question. So about six months ago, we were talking about customer commitments of tens of megawatt-hours and indications of hundreds of megawatt-hours for SiMaxx. Are most of those commitments for customers that can switch over to SiCore, at least in the interim, if that's the first line you're going to have up and running, and maybe even utilize some of the toll manufacturing in the interim? Or can you help kind of understand what the customer evolution is a little bit better as far as switching over to this newer product just because you're going to have a lot more capacity quicker for that product?

[Kang Sun, CEO at Amprius Technologies]

Yeah. The customer, Chris, customers who are interested in SiMaxx, they would not easily shift to the SiCore because, as you know, we sold out our 2024 capacity for SiMaxx. The demand for SiMaxx is still very strong. So the customer wants to have a SiMaxx product for a reason. SiMaxx not only offers super high energy density, also offers very high power capability. We have a customer interested in both products, but I have not seen a customer willing to compromise, say, "Since SiMaxx is not readily available, I'm going to use SiCore.

[Chris Souther, Research Analyst at B. Riley Securities]

Okay. So what are the conversations like as far as those customers who were expecting the first line to be in Colorado to be SiMaxx, and now it might be a little bit further that they'd have to wait? Is that going to impact any product launches with some of the key customers you've talked about previously, or how do you kind of address that in the interim? I'm curious.

[Kang Sun, CEO at Amprius Technologies]

At this time, our design likes to have a first line for SiCore. That doesn't mean we have to wait for two or three years to build a SiMaxx. So the SiMaxx, by the year end, we have a full manufacturing protocol for SiMaxx validated at Fremont with this 2 MW facility. So we are ready to go larger scale. For now, our plan is we design this factory not only for SiCore, also for SiMaxx. We just procure our first line production line for SiCore.

[Chris Souther, Research Analyst at B. Riley Securities]

Okay. And then can you quantify in any way beyond the customer numbers being impressively quick to grow here, how commitments and indications are for SiCore that you're kind of prioritizing that one for the first line? And are there significant expectations of CapEx savings for that initial line for SiCore versus SiMaxx?

[Kang Sun, CEO at Amprius Technologies]

Yeah. SiCore line, of course, is based on our estimates, SiCore line is relatively lower cost. Okay? This is an off-the-shelf production line, right? So it's a proven manufacturing process. Currently, we are using a toll manufacturing partner to do it for us. We know exactly how the process looks like, how the machine configuration is.

[Operator]

As a reminder, it is star one on your telephone keypad if you would like to ask a question. Our next question is from Jeff Grampp with Alliance Global Partners. Please proceed.

[Jeff Grampp, Senior Analyst at Alliance Global Partners]

Afternoon. Curious, going back to the customer count that you guys had in the quarter, curious if you guys have kind of a percentage or rough numbers that are taking both SiCore and SiMaxx, and wondering if you have a sense or any insight as to the ones that maybe are taking both. Is that to maybe assess a better fit within a specific use case, or might there be customers that could ultimately be customers of both products for differing use cases? Any insight there?

[Kang Sun, CEO at Amprius Technologies]

As we mentioned in our call, half-quarter, primary driver of our revenue last quarter, actually, we have almost the people purchase the equal amount, SiMaxx and SiCore. But we have a lot more new customers for SiCore products because we have capacity available to them. If we have had more capacity for SiMaxx, we would have a lot more SiMaxx customers as well.

[Jeff Grampp, Senior Analyst at Alliance Global Partners]

Understood. That's helpful. For my follow-up, maybe for Sandra, any rough numbers or timeline in terms of when you guys might have a final number to share publicly on the cost of Colorado? Is that something that's months away, a year-end, or just any kind of benchmark to kind of think about here without holding it to too tight of a timeline?

[Sandra Wallach, CFO at Amprius Technologies]

Yeah. We've completed the 30% construction drawings. We believe we'll have the 100% construction drawings at the end of the summer. That'll allow us to get a more high-confidence cost estimate as well as the schedule. I think we should be able to give some sort of guidance in exiting the third quarter.

[Jeff Grampp, Senior Analyst at Alliance Global Partners]

Great. Look forward to it. Thank you.

[Sandra Wallach, CFO at Amprius Technologies]

Thank you.

Our next question is from Amit Dayal with H.C. Wainwright. Please proceed.

[Amit Dayal, Managing Director of Equity Research at H.C. Wainwright]

Thank you. Good afternoon, everyone. With respect to sort of this ramp in new customers, how should we think about revenues for 2024, given that you do have the tolling capacity available? Is there anything in the pipeline that could materialize into sort of an order that is larger than everyone is sort of expecting at this point that could move expectations for 2024 higher than where they are?

[Kang Sun, CEO at Amprius Technologies]

As you see, we have a very impressive number of customers today. So at this moment, we don't know which customer can finish their qualification process. We have some customers already placed orders for their commercial use. But we have a large fraction of the customers just engaged with us, started purchasing small quantities of the batteries for qualification. I think we may have more clarity end of the day in Q2, later part of Q2, which customer can start offering our larger orders.

[Amit Dayal, Managing Director of Equity Research at H.C. Wainwright]

Okay. Understood. And then the $2.3 million in sales for 1Q, was it all SiMaxx? If you could just maybe give color on what the mix was between SiMaxx and SiCore.

[Sandra Wallach, CFO at Amprius Technologies]

Yeah. Great question. So it was roughly 50/50 between the two.

[Amit Dayal, Managing Director of Equity Research at H.C. Wainwright]

Okay. The SiMaxx was coming from.

[Sandra Wallach, CFO at Amprius Technologies]

Oh, no. It's a little bit. I'm sorry. It's a little bit more. I gave an answer too fast. It's about $1 million in SiMaxx and about $1.3 million in SiCore.

[Amit Dayal, Managing Director of Equity Research at H.C. Wainwright]

Okay. And SiMaxx all came from Fremont?

[Sandra Wallach, CFO at Amprius Technologies]

Yes.

[Amit Dayal, Managing Director of Equity Research at H.C. Wainwright]

Okay. Yeah. That's all I have, guys. I'll take my other questions offline. Thank you.
