This afternoon, we will review our business as well as results for the quarter. With that, I'll pass it over to Qichao.

Thanks, Eric. 2023 is starting out to be a great year for SES. A few years from now, when our lithium metal battery technology is in mass production, I think we will look back and say 2023 was a key turning point as we laid several crucial foundations. First, I'd like to give you an update on our 3 OEM JDAs. As we have discussed previously, we were the world's first lithium metal battery company to enter automotive A-sample JDAs, and we did so with GM, Hyundai and Honda. Our biggest value to them, in addition to deep material development capability, is the ability to build and test many large 100 mPOWER lithium metal cells. With this ability, our ideas become data and data become intelligence. Even Elon Musk tweeted after the Starship launch that high production rates solve many issues. It's been more than a year now since our 3 A-sample lines have been up and running, 1 in Shanghai, China and 2 in Chungcheongbuk-do, South Korea, producing and testing large 50 mPOWER and 100 mPOWER lithium metal cells. These are the most advanced and battle-tested large lithium metal cell production lines anywhere in the world. And what a difference they have made. They provide a safe and reliable platform for us to test new ideas and make improvements to the technology. It is safe to say, as we have discussed on previous calls, we simply didn't know what we didn't know until we started making these large cells in higher volumes. Many of the manufacturing issues that we detailed have now been solved or are close to being solved. For example, ultrathin lithium anode wrinkling and tearing during large-format rolling and lamination. After 3 rounds of iterations and improvements on our A-sample lines and in collaboration with our equipment and material vendors, we have significantly improved this issue. We have even started testing new processes for anode lamination and believe we will completely eliminate these issues in future designs. Second, novel electrolyzed solvent scale-up. While our material R&D team continues to develop new solvent molecules, our scale-up team has completed 4 different types of electric solvents for production. Third, electrical stacking misalignment and overhead. Our approach of manufacturing lithium metal cells using the lithium-ion process really paid off here as our team of experienced lithium-ion engineers quickly addressed this issue by borrowing from their lithium-ion stack power cell experience. Fourth, powder formation during electrical punching. This is unique to our lithium metal anode, and we now have 2 teams working on laser and metal die approaches in parallel. Understanding the fundamental mechanism, we will be able to choose the best solution after fully understanding both approaches. Five, formation pressure and voltage stability. This is also unique to our lithium metal cells. And after 3 rounds of iteration and improvement and working with our vendor, we now have a solution that we will implement across our current equipment and future designs. Six, finding efficient ways to do image scanning on large-format cells and developing top ways to store, handle, test and recycle lithium metal cells. This is a really interesting and important area that many companies don't pay enough attention to. We are integrating imaging tools, including x-ray, CT, SCM, ultrasound and others to our manufacturing and Avatar systems. We're also developing new tools such as large 100 mPOWER lithium metal cell teardown robots, smart test boxes and very sophisticated large cell testing and monitoring facilities, all to provide a safe environment for us to innovate and test cutting-edge ideas on large 100 mPOWER lithium metal cells. And seventh, our large cell Avatar prediction accuracy increased from 0% to 60% last year. In a recent experiment, our Avatar successfully predicted 18 out of 21 abnormal cells. That's getting pretty close to 90%. Furthermore, we significantly improved quality management through diligently working with our OEM partners. For example, our control plan went from about 200 control points to more than 1,400 control points. We are targeting more than 4,000 control points. Since lithium metal is a new technology, and we want to fully characterize every little detail in the entire process, these issues could not have been addressed through simulation or discussion. They required extensive trial and error, and that's what our 3 A-sample lines did, building and testing hundreds to thousands of large 100 mPOWER lithium metal cells to perform a massive universe of experiments. I don't think any other lithium metal battery company is capable of doing this. And if you don't do this, you just can't push lithium metal forward. We didn't stop there. These 3 A-sample lines are already the most advanced in the world for large 100 mPOWER lithium metal cell production. But we want to integrate all the learnings that we have accumulated and build a brand-new line, one that is a leapfrog, at least 1 generation ahead of our 3 A-sample lines. This is our Line 4. Line 4 will be for the next phase of automotive large 100 mPOWER lithium metal cell development, basically B-sample. Compared to the current 3 A-sample lines, Line 4 will have many of the new concepts, including Avatar integration and rigorous quality control plan built in from this design phase. The exterior facility build-out is already completed. We expect the dry rooms to be completed this summer and equipment to start arriving this fall, with the entire Line 4 to achieve ready-to-use status in the first half of 2024. This will be a key enabler for us to transition to B-sample, which we're still on track to achieve this year. Lastly, I want to quickly address our stock price. Frankly, it's not something I think about every day. Recently, we had our 1-year anniversary since listing on the NYSE, and we completed 2 procedural filings. One was the S-3, which allows us to fundraise in the future, although we have no plans to fundraise anytime soon. Another was the Form 4, where management, including myself, recently reported the sale of shares purely to cover taxes on vested RSUs. I, as the founder of SES, have never sold a single share other than to pay taxes or made a single dollar from our stock since I started the company 11 years ago. I just wanted to clarify these 2 issues in case there have been any misinterpretations. I'm super excited about the progress that we are making. It was painful last year, but now it's fun again. Our new Line 4 will be a step change in our development roadmap and a major part of the transition to B-samples. We will continue to keep you posted as we take additional steps to get Line 4 up and running. With that, I'll hand the call over to Jing to review our financials.

Thank you, Qichao. Good afternoon, everyone. Today, I will cover our first quarter financial results and discuss our operating and capital budget for full year 2023. In the first quarter, our operating expenses were $21.6 million, an increase of $2.4 million from the same period last year. Stock-based compensation expense was $6.5 million in the quarter. We reported research and development expenses of $8.5 million, an increase of $4.4 million from the same period last year. This increase reflects higher personnel costs due to increased headcount to support battery cell development, an increase in lab consumables and material supplies, an increase in development costs related to our advanced AI software and battery management systems and increased facility costs. Our gross R&D spend in the first quarter was $11.7 million, which was offset by $3.2 million billed to our OEM partners, which are treated as contra R&D expenses. Our G&A expenses were $13.1 million, a reduction of $2 million from the same period last year. This decline resulted from a decrease in transaction costs incurred as a result of the business combination during the first quarter of 2022, which was partly offset by an increase in personnel costs and professional fees to support our operations as a public company. During the first quarter, cash used in operations was $15.4 million. CapEx for the quarter was $6 million, reflecting payments for equipment and facilities. Looking at liquidity, our balance sheet remains very strong. We ended the first quarter with combined cash, cash equivalents and investments in marketable securities of $373 million. We continue to believe our liquidity is sufficient to get us to commercialization. For 2023, our financial guidance is unchanged. We continue to expect cash usage from operations to be in the range of $80 million to $100 million and capital expenditures in the range of $50 million to $70 million. In total, we expect cash usage for the year in the range of $130 million to $170 million. This higher level of spending compared to 2022 is necessary to support our growth as we expect to transition from A-samples to B-samples in 2023. Significant areas of spending in 2023 continue to be for headcount, lab expansion, equipment, manufacturing facilities and materials. Lastly, SES became eligible to file an S-3 registration statement following the first anniversary of our business combination with Ivanhoe Capital Acquisition Corp. Our S-3 was filed with the SEC on April 25 and became effective on April 28, 2023. It includes a universal shelf registration, which will allow us the flexibility to raise capital from time to time up to an aggregate $300 million. While the headlines related to these types of filings can be confusing, to be very clear, we have no near-term plans to raise capital. 2023 is shaping up to be an exciting year of growth for SES. We appreciate the support of our shareholders, employees and OEM partners. With that, I'll hand the call back to Eric.

Thanks, Jing. Cole, you can now open the line for questions.

Our first question is from Shawn Severson with Water Tower Research.

Qichao, I wanted to discuss Line 4. You previously mentioned bringing several manufacturing technologies in-house. There were some difficult issues, and you believed your team could handle it better. Could you explain the changes being implemented in Line 4 and how it differs from the existing setup?

Yes, sure. Thanks, Shawn. So in the first 3 lines, essentially starting in Line 3, we started incorporating all the aspects, the cathode coating, anode coating in-house. But then it's still fragmented. And then we still don't have a very systematic way of collecting data for Avatar, also the number of control points. We started out with just 200 and now 300. It's hard to add all these additional sensors and increase the number of control points from just 200, 300 to 1,400. So in Line 4, a couple of things. One is it will have every aspect, cathode coating, anode coating, anode lamination stacking. So Line 4 will be the first complete line in terms of our ability to make every aspect. From the design phase of Line 4, we already incorporated these 1,400 control points. Whereas in the older Line 3, we had 200 and then we added in a fragmented way to 300. But in Line 4, from the beginning, it will have every aspect in-house. All these sensors and the data will be compatible and then integrated with Avatar. So it's really a step forward, at least 1 generation ahead of just the first 3 lines.

And from a manufacturability standpoint and a cost standpoint, are there any big-ticket items that are still in your sights to target cost reductions for as you go through B and, of course, eventually into C? Is there anything in particular you'd point to that is a great opportunity for further cost reductions that we should monitor?

Yes. So in the first 3 lines for A-sample, the yield was always quite low, and yield wasn't really a consideration for A-sample. Basically, A-sample was just about building the cells, testing the performance, and not worrying about yield as much. So the cost is obviously not very meaningful because we don't have a rigorous way of controlling the yield. But this Line 4 and then B-sample later will be the first line that, in addition to all the performance and capabilities that we built based on the A-sample, Line 4 will be the first line that we will actually track yield. Line 4 will have significantly higher yield than the first 3 lines. It will be the beginning of a phase where yield becomes a very meaningful consideration in addition to performance and other considerations from A-sample. So yield is a big consideration for lowering costs.

Our next question is from Winnie Dong with Deutsche Bank.

My first question is also on Line 4. In the shareholder letter, it says that it would be critical to B-sample. It states that the equipment will start to arrive in the fall and that the line will be entirely ready for use in the first half of 2024. But then it also seems like you're still on track to achieve the transition to B-sample this year. So I just wanted to confirm if the transition to B-sample is or is not dependent on Line 4 being fully ready. Also, maybe provide an update on the latest timeline for that transition.

Yes. For example, back in 2021, when we entered A-sample, the definition of entering into A-sample or B-sample is basically starting the process of developing a B-sample. Line 4 is going to be a key part of the process of developing B-sample. However, we will enter B-sample this year, in the second half of the year. Line 4 is part of that. It's not like we only start B-sample after Line 4 is ready. We start B-sample, and then part of the work of B-sample is getting this Line 4 ready. There will likely be Line 5, Line 6 for the 3 OEMs. So Line 4 would likely be the first line in B-sample, but we will enter into B-sample in the second half of this year.

Got it. And to confirm, so far, you indicated B-sample with one of the OEMs, is that correct? Or is there anything that changed in that regard?

Yes. I think we will enter into 1 first and then the other 2 will come later. But from a technical perspective, the requirements are quite similar, and the capability that we've built along with the capability we increased by having Line 4 will be transferable across all the 3 OEMs.

Got it. And if I can sneak just one more in, this is more of a theoretical question. If we fast forward to, let's say, 2026, in an ideal world with everything going according to plan, understanding that it might not, right? Most likely, you finish B-sample by end of 2024, and if B-sample takes maybe another 12 months or so to finish, what would ideally have taken place by then in 2026? Would it be a plant with a JV ideally up and running? Or do you start the build-out of that plant in the U.S.? I'm just trying to get an idea of your internal roadmap, even with the understanding that it's not set in stone.

Yes, sure. So we enter B-sample in the second half of this year, and then in '24, next year, towards the end of B and beginning of C, that's when we will sit down with the 3 OEM partners as well as potentially large-scale battery manufacturer partners. We will plan the location and resources for C and SOP. A and B are similar and considered together along with the pilot scale plant. But once you get to C and start planning for C, you also plan for SOP. I would say towards the end of B, when we transition to B, a year to 18 months from now, we will plan the North American site for lithium metal battery manufacturing as well as the supply chain.

Our next question is from Timothy Johnson.

In the recent past, you mentioned some work being done on the anode-free concept. Can you please update us on where you stand with that?

Sorry, can you ask the question again? The recent work on the anode and the what, the second half?

On the anode-free where you take out the lithium foil and all of the lithium for the anode comes from the cathode upon charging.

Yes, yes. So on anode-free design, it's one of the next-gen projects that we are exploring. All the lines that were used in the 100 mPOWER cell lines, the 3 lines for A-sample and then on Line 4, all of these can be used for anode-free as well. We are actively building and also testing anode-free versions of these 100 mPOWER lithium metal cells. When I say 100 mPOWER lithium metal cells, they come in different versions, anode-free version as well as lithium version. We have the capability to test these, and perhaps later this year, we can disclose more data. For now, the anode-free version of 100 mPOWER lithium metal cells, we are primarily considering these for drones and eVTOL, the urban air mobility applications, less so for the EV applications.

Our next question is from Dennis Hugh. I'm not sure if Dennis has disconnected or not, but there are no additional questions waiting. I will pass the conference over to the management team for any closing remarks.

Yes. I think this past quarter, especially after 2022, was when we first built these large 100 mPOWER lithium metal cells. People thought it was a big leap and crazy to build these large lithium metal cells. It was really difficult, and at times, we felt we were crazy too. But now, this quarter, things have turned around. A lot of what we learned has finally started to come together. Line 4 is really the first time that we take all the learnings from A-sample JDA and then combine them all, leveraging all the capabilities, all the knowledge and the new ideas. We are really excited about 2023 and just the future capabilities. I mean, also on Line 4, you can imagine a year from now, we will be on Line 7, right, the first line for C-sample. I’m just really excited about the progress and can't wait to share more good news with you all.

That concludes the conference call. Thank you for your participation. You may now disconnect your line.
