Joe, John and Alessandro will walk you through our business outlook and financial results before we proceed to Q&A. With that, I'll now turn the call over to Eos's CEO, Joe Mastrangelo.

Thanks, Liz. Good morning. Thanks, everyone, for joining us. This quarter comes down to three simple things. We ship more product than we have in any prior quarter. We grew our backlog and we committed to consolidating our manufacturing footprint, a strategic decision that trades near-term revenue to lower our cost base as we exit 2026. Now let me walk you through all three of these. We're tightening our 2026 revenue outlook range to $300 million to $350 million. And this is a business decision, not an operating surprise. Let me address this change directly. We are accelerating the consolidation of operations into our modern Thorn Hill facility because what it has begun to deliver. Line 1 will be down during the move and upgrade it to the operational improvements we've implemented on Line 2. The volume that would have produced is the difference in the upper end of our guidance range. We're doing this so that 2027 is not only a volume growth year, but also a margin expansion year. John and Alessandro will take you through the operational and financial expression decision in a few moments. The low end of this range is roughly 2.5x our 2025 revenue and more than 19x in 2024. We delivered just under $126 million in the first half, which already exceeds all of last year's revenue. Let's frame the range itself. While we are still finalizing the detailed schedule, the shape is very clear. The second half exceeds the first half, the fourth quarter is higher than the third. The bottom of the range takes roughly $50 million of second half growth over the first half. That is just maintaining the run rate that we exited June with on, revenue already secured through backlog in Frontier Power USA. The top end of the range is achievable and it comes down to how quickly we scale Thorn hill operations in a 24/7 production facility like we have today in Turtle Creek. We're planning for that, and we'll report against it every quarter. Moving to Slide 5, our second quarter operating highlights. We achieved record backlog, record revenue, record cube shipments and a significant improvement in adjusted EBITDA margin. We're starting to see the operating leverage we've been talking about. As volume increases, fixed costs are spread across more cubes and that's which drives margin improvement and closes the profitability gap. John and Alessandro will take you through the details behind those numbers and our path forward. But before they do, I'd like to spend a moment on fleet performance and cash. First, discharge energy. The number we're looking at, at the page is up nearly 0.5 gigawatt hour since our last call. The fleet now cumulatively has discharged 6.5 gigawatt hours of energy and the Z3 fleet continues to perform, operating at an average round trip efficiency of 78%. Let me be precise about that number because precision is what matters here. 78% is the average across a 20-100-20 state-of-charge window. It includes units running on DawnOS and the units have not yet been upgraded to DawnOS. So the performance of what we've developed, but we're continuing to count that performance of where we still have to improve to show the true number of what customers are experiencing out in the field. It's a fleet average under real duty cycles, not a laboratory result on a single unit. We're starting to scale here. We have more work to do but there is a clear path to continue to improve performance. Turning to cash. We ended the quarter with $364 million in total cash. What's important is what sits behind that number. Our operational cash use this quarter closely matched our adjusted EBITDA loss. Cash on cash, there was very little gap between the P&L and cash flow. That burn rate needs to continue to come down and term positive. And the initiatives that John and Alessandro will walk you through are designed to drive that improvement. Now let's move on to Slide 6. Let's focus on what wins our next order, reference hours. This page shows the hours the fleet has already delivered and the continued growth ahead with more than 200 additional megawatt hours expected to come online over the next 6 months based on current customer project schedules. Let's start on the top left of the page. The fleet has now run over 3.9 million cycles and discharge 6.5 gigawatt hours I talked about earlier. On Z3 specifically, over 1.1 million cycles. We're moving towards 1 gigawatt hour of discharge energy. Every hour of cycling makes the next project easier to finance because customers can now evaluate a track record, not a promise. Round trip efficiency tells a more interesting story. Note how the performance range is narrowing. The bottom is rising towards the fleet average. That is variation coming out of the system and reducing variation is what makes performance bankable. At the same time, the top of the range has crossed above 90%. In manufacturing terms, that is entitlement. It is what this technology delivers when everything runs designed. It is not a ceiling we hope to reach. It is a level the fleet has already demonstrated, and now our work is to deliver it consistently across every cycle, every cube in the field runs. The duration tile shows the range our systems are operating in the field. From 2.5 hours to 14, 1 product, 1 SKU dispatch, however the market needs it. The photo on the right is a project that was added into our backlog in November of 2024. I want to use it to show you how a pipeline opportunity becomes an asset operating in the field. The units are built and shipped by November 2025. They went on foundations in May of June of this year, and the project is expected to come online by year-end. Ordered operations roughly 2 years and noticed where the time went. The product was ready in 12 months. The second year was everything else from site readiness to third-party equipment delivery outside of our scope and the site construction schedule. That is one of the industry's key bottlenecks and it's exactly why Frontier Power USA was built to simplify the process and streamline the customer experience. The next page highlights how that strategy is translating into results. On Page 7, the U.S. storage market is changing in ways that favors our technology, load growth from data centers and electrification is pulling capacities forward faster than new generation can interconnect. In PJM, the grid operator for 65 million people and the largest power market in the country, prices have hit the ceiling in 3 consecutive capacity auctions. And the way the market now counts a resource towards capacity, favors those that hold output to the system, full system need rather than the first 2 hours of it. Virginia has written the same logic into law this spring. The statute carves out 4.5 gigawatts for resources that run 10 hours or more, inside its total state storage target above 20 gigawatts. At the minimum duration, that carve-out alone is 45 gigawatt hours of energy. Buyers are no longer procuring just a storage system, they're procuring hours. Inside of this, we see 4 customer types. Energy providers and regulated utilities who generate revenue from assets. energy consumers and assurance buyers who carry them as a cost of operations. The largest energy providers are independent power producers who need to deliver multi-hour and multicycles day after day because those capacity payments reward duration and energy margin rewards throughput. Utilities need assets that regulators will allow them to earn a return on over a 20-year life. Think about that for a moment. An energy provider an IPP uses that discharge window I talked about earlier. And when we've always talked about the degradation of our product over time and having a 25-year life, helps you utility with its regulator and its rate base. And if you move over to the largest energy consumer, that's high-speed computing, where power is just the cost of goods sold. Think of a data center as a factory and think of energy storage or energy coming in as an input for them to produce. So storage is judged on delivered costs, how fast the site can energize and how reliably it will operate. The Assurance segment is made up of defense or critical infrastructure customers, where storage is priced against the cost of failure and the rapidness of being able to perform. Two book it as revenue, one book that is cost of goods sold and one book it as insurance, all 4 by hours and all 4 screen for supply chain origin. We manufacture in Pennsylvania with the domestic supply chain. That is a commercial advantage today, not a future one that we're planning on. The pipeline on this slide is built from all 4 of these customer types and the composition is where we are focused. I talked about backlog earlier. But what's important to note is that 6 customers placed orders this quarter, 4 new and 2 repeat. Our pipeline of $24.6 billion, nearly 112 gigawatt hours is up 31% year-over-year. 51% of the pipeline is 8 hours longer. That is the duration band where our economics separate from incumbent technologies. 32% is data center related, which 2 years ago was a de minimis amount. Three commercial developments framed the second half. After the quarter closed, we were awarded a strategic partnership agreement under Golden Dome for America -- for the Golden Dome America program with the U.S. Department Award. During the quarter, we signed a 750-megawatt hour master supply agreement with CAPAC covering Germany, Austria and Switzerland. And Frontier Power USA holds a 2-gigawatt hour capacity reservation agreement. Under that agreement, we are now seeing purchase orders convert into projects, beginning with the Bimergen project and most recently with the $100 million purchase order we announced this morning for Phase 1 of the Blanquilla project in ERCOT originally developed by Stella Energy. I'll highlight the obvious with nearly $25 billion of pipeline against an $807 million backlog. Our job is conversion, not origination. Capital availability is one of the critical opportunity conversion factors. Two slides ago, I mentioned we built something to improve it, and that now brings me to Frontier Power on the next slide. Frontier Power USA, it's working as we intended. We have started execution on our first project because our priority is to get more projects into the field, begin generating returns and begin the operating references that help turn the investment flywheel up Frontier Power and deliver that pipeline conversion I was talking about a moment ago. We saw that strategy beginning to play out in the second quarter. A pre-existing project that will ultimately be part of Frontier Power USA was executed prior to the closing of the joint venture, using financing provided by a service affiliate. That project accounted for roughly 80% of second quarter revenue. It demonstrates how this structure can help us get projects into the field sooner and build the reference hours that support future growth. Adding this project is an asset that we believe will deliver mid-teen returns and accrete the value of the joint venture in which we hold the minority interest. I'm putting that on the table first because I want you to understand it is a strategy rather than just a footnote. Our pipeline has historically experienced delays closing project financing, not technology acceptance. We saw qualified projects with real offtake sitting unbuilt because developers could not close their capital stack. So we've built the vehicle. Frontier Power USA supplies the capital, Eos supplies the technology, and we hold a minority interest in the entity. Walk the left side of the page, $263 million of gross proceeds initially raised, supporting an estimate $1 billion project deployment, the funnel behind it. 16-gigawatt hours of opportunity pipeline, 5 gigawatt hours acquired, selected or under active due diligence and 1.8 gigawatt hours under construction are approaching full notice to proceed. First projects under this vehicle are expected to be online by the third quarter of 2027. That is the project journey I showed you 2 slides ago, running at platform scale with capital waiting for projects instead of projects searching for capital. Now in the middle of the page, because this is a long-term operating asset and it creates value in three ways. Frontier Power USA operates projects for recurring revenue. It can sell projects and recycle the capital with new ones and at scale, the platform itself becomes highly valuable. Eos participates in all 3. We are the long-term service agreement counterparty across the small fleet with up to 25% to 30% of total CapEx over a 20-year life. We hold economic ownership in the platform so we share in the recurring cash flows, the project sale proceeds and any future monetization of the platform. In every project, Frontier Power USA puts into operations, ads, reference hours to the installed base and to that chart I showed earlier, which will accelerate the next order and backlog growth and conversion of pipeline into orders, orders into assets operating in the field. APAC, the U.S. Department Award and the customers who placed orders this quarter growing. Both engines are running, and they compound as we execute our strategy and projects become operational. So we have a strong demand signal. We are building installed base operating hours as a capital partner that unlocks accelerated growth. Strong execution delivers profitable growth. And let me turn it over to the man responsible for all that John for an operational update.

Thanks, Joe, and good morning, everyone. Q2 was about focus, disciplined operation and increased efficiency. Turtle Creek delivered on all 3. Cube output increased 20% sequentially reaching an annualized production rate of approximately 1.5 gigawatt an hour in June. More importantly, we achieved that while keeping labor costs essentially flat. On materials, we're beginning to see the work we've been doing translate into lower cost. Material costs improved by 10% sequentially, with the benefit of tariff free base paid in prior periods on an imported components. Excluding that, material cost per cube improved 1% sequentially. We expect further improvement in the third quarter as inventory balances are worked through production, and we realized the benefits of our cost reduction initiatives. More broadly, there is a continuous learning cycle in our business where we take feedback from the field and incorporate those learnings into the design. While that can add cost in the short term, it ultimately drives meaningful cost reductions over time. When we launched DawnOS in the third quarter of 2025 material costs increased as we noted on our last earnings call. Since then, we have reduced material costs by 12.5% in less than a year. At the same time, we invested in product enhancements throughout 2026 based on the field earnings. Had those enhancements not been incorporated, material costs would have been down 14.5%. We achieved this despite elevated inflation of volatile geopolitical environment and a continually evolving product design, which reflects the strength of our continuous improvement process. Labor productivity also improved during the quarter. Direct labor cost per cube declined 20% sequentially, while production increased, reflecting better execution and increasing efficiency across the factory. Manufacturing overhead per cube improved 4% sequentially. However, if you look at Turtle Creek on a stand-alone basis, overhead for cube improved approximately 16%, reflecting the productivity gains delivered by the team at the Turtle Creek plant. The consolidated result was temporarily impacted by the underutilization of Thorn Hill as we brought Line 2 into commercial production. That's exactly what we would expect at this stage of the ramp. As planned, we have been operating on one partial shift while we validate the line's performance. This phased approach allowed us to add labor incrementally as we ramp up that line. Over the next several months, we'll continue to add shifts and increased utilization. As volumes ramp, we expect utilization to improve, fixed costs to be absorbed across greater production and the operating leverage built into Thorn Hill to become increasingly evident in our results. While we're pleased with the progress that Turtle Creek, our focus is not simply on incremental improvements. Our focus is on achieving the cost structure we've always envisioned for the business. That's where Thorn Hill comes in. The biggest opportunity ahead of us is not just the continuation of what we've already accomplished is the earnings power we unlock as we fully utilize a purpose-built, highly automated manufacturing platform. During the first half of 2026, we produced 17% more cubes than we did in all of 2025, and we matched last year's total production volume in just 164 days. What's most important is that scrap dollars on that same volume were down 63%, validating that our manufacturing platform is scaling as planned. With Line 2 contributing only 1% of second quarter production, we have yet to realize the full benefit of Thorn Hill, leading significant operational upside ahead. Thorn Hill is already delivering the performance we intended. Initial Line 2 battery cycle times are 10% faster and bipolar cycle terms are 11% faster than Line 1, with additional redundancies built in to improve line availability. That drives a near-term increase in overhead per cost cube and an improved as we scale production, and we will continue to improve performance from here. As we move through the third quarter, we're evaluating the timing of consolidating Line 1 in the Thorn Hill. There is never a perfect time to make a move like this. You have to balance execution, customer commitments and operational continuity. That said, after years of operating manufacturing facilities, I've learned that the sooner you pick a path, the sooner you begin realizing the benefits, waiting rarely creates value. Consolidating the footprint will allow us to upgrade Line 1 to the same single piece flow design, while at the same time implementing redundancies to remove a single points of failure. The focus becomes much clearer. One building, multiple production lines, one overhead structure and more volume going through the same footprint. Based on our current analysis, we believe this initiative alone could deliver an additional 10% to 15% reduction in conversion costs on top of the improvements already embedded in our current operating plan. Achieving those savings would require a modest investment to relocate and integrate Line 1 in Thorn Hill. But even after accounting for that investment, we currently estimate a payback period of approximately 9 months. This is what positions us to 2027. It is the foundation for the margin improvement, Alessandro will walk you through on the next page. Thanks, everyone. With that, I'll turn it over to Alessandro.

Thank you, John, and good morning, everyone. Before I start to discuss the quarter, let me say that it's a privilege to be here, and I want to thank the entire U.S. team for the company that they have built and the progress that they've made over the last few years. I followed Eos for several years, first as a shareholder and now for the past 2 months as a CFO. Over the last 25 years, I've led finance organization across global energy and industrial businesses. What brought me here was the combination of a unique vision and differentiated technology, and expanding market and a business at an operational inflection point. Before I joined, I visited our manufacturing facilities. Having spent most of my career around industrial operations, the level of automation stood out. Eos designed this platform for the volume the business is growing into rather than the volume it adds, and that decision is now paying off. I strongly believe that Eos is at a real keeping point. Looking at what the team has built gives me tremendous confidence in the opportunities ahead. I believe I bring an operational mindset that complements the team with a particular focus on execution and margin expansion. I'm excited to be part of the next phase of growth and to help translate the scale we've built into stronger profitability and long-term shareholder value. I want to finally thank Nathan for this partnership through the transition and for the financial foundation he has established. With that, let me turn now to the second quarter. Revenue increased to it's highest of $68.8 million, which is up 351% year-over-year and 21% sequentially. With cube deliveries increasing 207% year-over-year and 20% sequentially. Now turning to margins. Gross loss totaled $48.8 million. Margin improved 132 points year-over-year and 7 points sequentially. Excluding stock-based compensation and depreciation and amortization, adjusted gross loss was $42.9 million, and an adjusted gross margin of negative 62%. This marks our seventh consecutive quarter of gross margin improvement and reflects the operational progress we're making across the business. The second quarter results also reflect the continued scaling of our manufacturing operations with some expected cost pressure as we invest in supporting that growth. In these regards, 2 items impacted the quarter. First, Thorn Hill. As you heard from John, a newly commissioned line operates below its long-term utilization targets, which weighed on fixed asset absorption. As throughput increases and the line matures, absorption improves. Second is field cost. Our installed base expanded, which drove higher deployment and commissioning activity, and we accelerated the DawnOS upgrades across portion of the legacy fleet. The improved field data that Joe discussed earlier is directly related to this work. Both reflect investment in supporting a growing asset base rather than a structural increase in our cost profile. We flagged these pressures last quarter, and we continue to expect in to diminish significantly by the fourth quarter. Operating expenses totaled $35 million, increasing 6% year-over-year while remaining essentially flat compared to the first quarter. While revenue increased 351%, we reduced the SG&A by 4% and increased R&D by 46% to invest strategically in the future software capabilities and product development. This clearly demonstrates the diligence around cost and cash management from the team. Net loss for the quarter was $276 million, with an adjusted EBITDA loss of $71.4 million. A margin of negative 104%, which is improving 235 points year-over-year and 16 points sequentially. Reported net loss continues to be driven primarily by noncash fair value adjustments related to our capital structure. Specifically, changes in our share price results in mark-to-market revaluation of warrants and derivative liabilities. As an example, when our share price increases, the value of certain warrants also increases, which can result in a higher account liability and a corresponding noncash expense. Those adjustments create volatility in reported earnings and do not reflect an operating performance. Now turning to the balance sheet and cash flow. We are encouraged by the continued improvement in how operating cash flow track adjusted EBITDA during the quarter with almost 100% free cash flow conversion from operations. Working capital did not consume incremental cash even as revenue grew 21% sequentially, and we continue to invest in the Line 2 build-out at Thorn Hill. As a result, we ended up the quarter with $364 million in cash. We remain focused on disciplined cash management, and we believe we are well positioned as we continue to improve margin. We are preparing the advanced request for the second year retranche and expect to close it by quarter end, subject to the conditions outlined in the loan agreement. Now let me close today's prepared remarks with the critical drivers to deliver positive adjusted gross margin. When you look at our history, product adjusted gross margin moved from approximately negative 983% in the second quarter of 2024 to negative 40% this quarter. That is more than 940 points of improvement in 2 years. Two years ago, we carried the cost of building a manufacturing platform well ahead of volume. We invested in automation, expanded the footprint, qualified suppliers and build an organization for the business we believe we could become. Over the last year, those investments become translating into performance. We increased production, improved yields, reduced manufacturing costs and benefited from the supplier economics as volume grew. This quarter continued our progress. Some of the manufacturing gains were offset by the project execution investments I described earlier. Those were deliberate, we chose to strengthen our ability to execute as deployments scale, and that choice creates near-term margin pressure. The heavy lifting of building the platform is largely complete and now the work is leveraging it. That is what the right side of this page shows. There are 4 drivers of cost out that we're pushing with detailed plans in place that John just walked us through. First, we anticipate a roughly 25% point reduction in material cost as a percentage of revenue. As backlog conversion becomes more predictable, we move from transactional purchasing to longer-term supply agreements. Additionally, the team is executing against more than 90 active cost reduction initiatives, focused on simplifying design, reducing material content and improving manufacturability. Second is conversion costs, approximately 20 points of reduction from the framework that John just walked us through. The step change comes from running under one cost structure. Supervision, planning, quality, maintenance and production support stay relatively constant, whether we run 1 line or 4. Materials management is one of our largest labor costs today and we move product between floors, buildings and warehouses with label intensive processes using temporary labor. At Thorn Hill, the majority of that movement is automated with conveyance and automated mobile robots. Third is project and field services, contributing another 20 points or so. As we said, we invested in the field this year through DawnOS upgrades while leveraging third-party resources. As that work is completed and we bring execution activities back to internal teams, project productivity improves and our reliance on external support declines. We are applying the same operational discipline, we have established inside our manufacturing facilities. We actually view the field as a factory with our walls and lead principles apply. As both projects become operational, we expect this cost to increase. However, we view this as an attractive opportunity over time and believe it can become a profitable area of the business as we continue to build and scale our internal capabilities. Finally, we expect approximately 8 points from continued yield improvements in our subassembly processes. We have already made solid progress here and as tooling and equipment upgrades are completed at a tighter component tolerance are implemented, we expect to further reduce scrap and improve first-pass yield. So combined, these initiatives provide what we believe is a clear path to over 72 points of adjusted gross margin improvement over the next 12 months, assuming we execute our plan and achieve expected production volumes. We have demonstrated that we can build the capability. The next chapter is converting that capability into earnings, and I believe we have a clear plan to get there. As we continue the base cost control, we expect adjusted EBITDA to improve with increasing operating leverage, with execution and volume growth, determining the pace of our improvement. While there is still work ahead, I'm confident in this team, I'm confident in the road map and excited about the opportunity to drive margin expansion. With that, I'll turn it back to the operator for questions.

[Operator Instructions] Our first question comes from Christopher Souther with Truist.

So just to kind of unpack the updated revenue guidance. And the path here, the low end is essentially 1.5 gigawatt hours for the rest of the year, just Thorn Hill and the high end? Are we assuming that Line 1 comes back online at Thorn Hill is producing as well?

Chris, so lower end is basically continue the run rate of June throughout the rest of the year to get to the 300. The higher end of that is to not so much get Line 1 up and running in Thorn Hill, but to get Thorn Hill the full 24/7 operation by the time we get into the -- at the end of the fourth quarter.

Got it. Okay. So if Thorn Hill is just 1% of 2Q production, what kind of throughput are we seeing today? And how close are we to kind of ramping that up towards the 1.5 gigawatt hour rate we need for the low end there?

So we'll continue to run Line 1 and Line 1 is running really well, and John has actually got Line 1 to its nameplate performance. And the team continues to bring Thorn Hill up into operations. But the Thorn Hill up in operations right now is more of the training and staffing of the people to run the line. So we'll go one -- the way what we've learned and we did Turtle Creek is get one turn up and running, add a second shift, get that up and running and go from there versus trying to do it all at once. But like what John and the team has done with the second line is nothing short of phenomenal when you look at the results you talked about on how the line has been performing initially.

Got it. Okay. And then I appreciate all the gross margin walk drivers to get to the 10% gross margins by 2Q of next year. Can you provide a bit more detail on some of the material costs and project drivers? I think the conversion in scrap are pretty clear, but would love to get a better sense on what the cost out initiatives are and the DawnOS and third-party labor like what those kind of drivers look like and how those progress over the next year?

So Chris, I think, and John and Alessandro can jump in. I think when you look at what the team is doing, having a clear revenue conversion plan now allows us to go out to suppliers and drive down costs, and we're seeing the costs like -- I think we talked about this in the presentation itself where 2Q, there was a little bit of timing, 3Q, we're seeing costs come down as we get into July. John will keep driving that with the team on supplier cost out. Then I think the second piece of this that you laid out is just part simplification, as you move through. It's taking DawnOS making the way the firmware and how we run the hardware that -- how we run DawnOS, simpler, taking cost out on that, scaling up with suppliers or going more from -- as we do this, we start off with a supplier that can move quickly to get us through prototype to initial production. And then John, with his relationships and background with [ Jabil ] and other contract manufacturers allows us to scale into a lower-cost solution to continue to drive that down. And then the third piece of it, which you talked about is as we've gone through and started and started ramping up and installing more megawatts out in the field, we started off just like we did when we did this in Turtle Creek, if you remember, we were talking about bringing in temp labor as we brought up Eos capability and then eventually phasing out that temporary labor and having be all Eos, you see that in the 7 quarters of improved margin that we've delivered. We're doing the same thing out in the field. You started off with people that worked out in the field, you build up your capabilities, we start off with supervision. Now we'll get into labor and we'll selectively use third party but drive down to a lower cost point on a labor input basis by using Eos employees to do insulation and commissioning.

Our next question comes from Stephen Gengaro with Stifel.

Two for me. The first one is, can you talk about the customer concentration that we see in the 2Q rev and the backlog that you mentioned in the press release. And how we should expect and what you expect to see from sort of a diversification of the customer base going forward?

Yes. I mean, look, Stephen, I think when you look at 2Q, like we had an opportunity to take a project that had a strong return profile added as an initial asset into Frontier Power, and we capitalized on that working with Cerberus, and it was, I think, a great move for us. When I think about what we're trying to drive with Frontier Power is we're trying to drive returns on the basis of individual project returns, which this does with the project that we're delivering right now. The same time, we create a pool of assets that can be monetized later on to spin the flywheel. And then also, I think owning 36% of an entity and when you look at comps of other developers like Frontier Power, it gives us the opportunity to be able to build the company and build valuation around that. I think inside of this, like, over time, there's going to be a blend of of bringing in both Frontier Power as we execute and then also price that are closing out in the market with third parties, and there'll be a blend of that as we move forward. I think the important thing for us is having sure you have a baseline of backlog conversion that allows us to load the factory that allows us to sign longer-term supply agreements because we know what we're going to need to deliver. And it just gives also the commercial team the ability to go out and sell slots in the factory to be able to accrete -- to deliver revenue and accrete margin.

[Operator Instructions] We have question from the line of Stephen Gengaro.

Sorry, Joe, I was muted, but just a follow-up to that in another question. But the follow-up was, I understand the FPSA side. But in your pipeline of opportunities and the customers you're talking to you, how should we expect that now 50% of your backlog is from that single entity. How should we think about that customer diversification evolving? Because that's something that we get a lot of questions on from investors. And I'm just curious, the conversations you're having like if we're sitting here 12 months from now, like how should we think about that from a nonaffiliated entity in the backlog.

I mean, Stephen, if we're adding assets that deliver returns in the Frontier Power USA., I think it's great. What I'd like to see is less percentages change and more of the size of the pie grow. And I think that's what we're focused on. I think getting Frontier Power and being able to execute quickly, getting projects referenced down the field, lead to the other half of that pie continuing to grow. We continue to work through that, and we're very selective. We do all the Frontier Power transactions at arm's length. So we're looking at projects that deliver returns and support long-term asset growth into Frontier Power. But at the same time, there's a large pipeline there that needs to convert and convert faster. And I feel really good when you look at things like what we announced in Germany. Germany, Austria and Switzerland, that's now landing real volume into Europe and allows us to expand in Europe. We feel also good about the recent announcement that we have with the Department Award because I think we talked about the specific program where we're in a strategic partnership. But Microgrids, and when you look at -- when you look at energy consumption, the government is one of the largest energy consumers in the United States. So being able to come in and show them that we have a solution that is American made fair compliant, all the things that we've always talked about that can deliver the diversity of cycling and applications, is another area that we're going to be able to grow. None of this moves as fast as you would like it to as we've been experiencing here over the last couple of months. But like when you look at where we are and where we want to go and the performance we're seeing out in the field, it gets stronger and stronger and stronger. So look, having a 50-50 split, I think that would mean that Frontier Power is doing its job, and we're growing a company like you see other project developers doing out in the market -- in the marketplace and having a partner where we can execute through would be great. And keeping that 50% split on the other side and making the pie bigger from the 800 is the goal that the team has.

Great. And when you think about the mobilization of Line 1 over time and consolidating the Thorn Hill, and there's sort of 2 questions behind that. One is, are you doing it now versus waiting because of just the timing of backlog delivering your ability to meet delivery obligations and Mobile line? Or is it because you've seen such higher efficiency out of Thorn Hill, and it's critical to driving margin expansion.

Yes, Stephen. Look, I think there was a couple of factors that came into this is -- just as you look at how the backlog conversion was laying out, we want to hit January running. Like when you look at this, like, we've seen the growth of the company, and I want to emphasize everybody that Turtle Creek is and could -- is operating to the nameplate. Just between the nameplate, just between all the movements and things you have to do it just becomes complicated. And this just simplifies. It's a simplification effort to get to scale next year. And I think doing it this year when we know we can execute both of them together, it just also takes the noise out of 2027 for us. And really focuses us on executing around the 2 lines. The other piece of this is John and the team with what they've done on Line 2 and the redundancies that they built in from the lessons learned in 4Q and other things that we've been able to do. And you see it in the results you put on this page, you see it and how it's performing versus Line 1. This is not about "Oh Turtle Creek doesn't work." It's a story of Thorn Hill works better. And why do we wind up where we wound up. Stephen, you and I have talked about this before. We moved into Turtle Creek because at the time we were setting up manufacturing, it's what we could afford. We expanded into areas of what we can afford. The line has laid out the way it's laid out in Turtle Creek as we had to fit it into the building that we can afford. Thorn Hill gives you now the straight shot to be able to do this without forklift, without pallet movers. It just simplifies the entire operation, which 5 years ago, we couldn't afford to do it. So we got Turtle Creek running the best that it could run, we knew we would come to this point. It's why we went out and negotiated to move into Thorn Hill and come up with a flagship factory. But when you go see it, you sit there and you say, "I see the difference." When you look at and you think about -- you've been in the factory, Stephen, when you think about the second floor of the building where we're manufacturing bipolars and you walk that floor and then go to Thorn Hill, you see and feel the difference of the efficiencies that we gain, the material movements and how fast things can flow. And the fact that John's got it running at 9 seconds is a testament to all the hard work that the team has done and the fact that, yes, we may have problems in everybody that scales in manufacturing operations. We'll stub their toe here or there, but we don't stub our toe in the same thing twice. And that's what the results are showing, and that's why we're doing what we're doing.

Great. And then maybe one quick one, and I don't know if you're going to be able to address this yet, but when we think about FP USA and your ownership position in that business, how do we think about the profitability of FP USA like when does that business become profitable? And then those profits kind of you've been obtaining the 1/3 of those profits?

Yes. So Steve, remember, this will be below the line profitability. It's not going to be operating profit. But like when you're talking about like initial projects coming online in second half of next year, once those start operating, then you should start seeing the profitability come through and the return on investment occurring as other income.

Our next question comes from Joseph Osha with Guggenheim.

One of the things you talked about last year, we haven't heard as much about recently is the data center opportunity, and in particular, some of the advantages that you felt like you have in terms of the ability to cycle, the ability to locate close to the building and so forth. I'm just wondering if we might be able to get an update there. And I'm curious to the extent you're doing anything, what kind of durations you're seeing your customers ask for?

Yes, Joe, so we did talk about data centers on the -- if you go back to the page on the pipeline, 32% of what's in the pipeline is data center related. And we've always talked about -- and you and I have talked about this in the past, there's 2 things. There's 2 segments within data centers. Segment 1 is co-locating with the data center. Segment 2 is having a storage asset in a generating area where data centers are going to be installed. We feel really good. I think on the second part, that's really what the talent relationship is all about is getting those projects with talent that will be in PJM and in Pennsylvania, and having them supporting the demand load from data centers. So a lot happening there. But obviously, we're at the time lines of how the PJM auction and backstop auction are going to work. So we're working through all those things. But feel really good about the work that we're doing with Mac and his team. On the locating directly on the site, continue to work through that. There's qualification work that you need to do. I mean, like as I talked about, like the more and more that I work with high-speed computing, you realize like we like to talk about, and think about energy storage as this great technological marvel and things that they can do and everything else. But from a data center, it's a cost of goods sold in a factory and their factory is high-speed computing. So they want to make sure that they have the reliability and performance that they need. We can perform on inference and do millisecond response times, we could do, as we've said many times, we do all the things that we talked about before that none of that has changed. It's a matter of working through with the suppliers to get to the point where we're going to be able to announce firm contracts with people building -- with putting and citing energy storage alongside a data center.

Okay. So it sounds like at this point, it's sort of more the grid level resilience for the near term at least than it is necessarily the on-site power quality, although that's evolving. Is that a correct way to think about it?

I don't know that I would term it that way, Joe, and I'm not going to handicap where we are in either one of those things. We'll announce as we come, but they're both moving and I think they're both moving -- they're both moving really well, and I'm proud of the work that the team is doing and the customers that are talking to us about that. That's not how I would characterize it.

Okay. And just on that other point I made about duration. One of the things we hear a lot is that the data center operators, hyperscalers, colos, whatever, are going to suppliers and saying, "Hey, we want rapid response time and all that." But we want pretty short duration of an hour or 2. I have someone else told me yesterday, they're shipping mostly 2 hours. So are you seeing requests in that part of the market for shorter duration devices?

The way I would term it, Joe, is you see multiple cycles and shorter durations that add up to longer duration discharge. And I think the reality of that is that plays into a strength of Eos of being able to cycle the battery multiple times in a day and have it be able to perform. So yes, like I don't know that the total amount is 2 hours because if you're running inference sessions and you have to cycle with our battery, you don't run the risk of the thermal runaway that you see with other technologies. So we feel really good about where that is. And I think -- and I've said this many times before, this is no different than any other segment in the energy industry. There's going to be a diversity of technologies required for use cases. And we have a big segment where our technology can serve a use case.

That concludes today's question-and-answer session. I'd like to turn the call back to Joe Mastrangelo for closing remarks.

Thanks, everyone, for listening today. Look, we continue to make progress. I think one comment that came out were very clear on the goal of the company is to become profitable and become EBITDA profitable, gross margin is a signpost and a journey to becoming profitable and generating free cash flow. And that's what we'll keep everybody updated on as we move forward. It's the focus of John and Alessandro, and the team. We continue to see strength on the commercial side, and we'll have to keep working through the opportunities in the pipeline, but are really excited about the ability to create and accrete value for our shareholders through Frontier Power USA through multiple avenues of just building up the potential returns of Frontier Power itself, but also Frontier Power giving us the opportunity to do better planning as we come out of the factory, to get assets out in the field running faster to get more references around the 6.5 gigawatt hours that we've discharged really excited about how DawnOS is evolving and the performance that we've seen. When I look at how we cycle, look, having a technology, we're not a technology that's 50 years old. We're a relatively new technology. And as we cycle, we learn from every cycle, we update our software and we get more performance out of the system. And as we talked about, like when you think about performance of Eos and its technology, you're starting to see the bottom end of our round chip efficiency creep up to the median, which means that the overall distribution is now skewing up to the high side. The next thing now is once you reduce variation as you shift the mean hire. Entitlement, you see it, we're running cycles at entitlement of 91%. We can run those cycles going back to the question that Joe asked like, if you look at the cycles we run, we've gone down to as little as 2.5 hours, 2.5 hours as high as the highest 11 or 14 hours off of the Z3 technology. It's a flexible technology that can meet multiple use cases. We've got to keep our head down and execute and make the company profitable, and that's what we're focused on as a leadership team. We'll keep everybody updated on the progress. Thanks for listening today.

This concludes today's conference call. Thank you for participating. You may now disconnect.
