Thanks, Liz. Good morning, everyone, and thanks for joining us today. Our team delivered a strong operating quarter. We delivered the most cubes in our history while continuing to drive product cost out. At the same time, our backlog came down from last quarter, and I'll come back to that on a later slide. There are 3 critical industry shifts that are shaping our performance. First, the power business has gone from managing retirements to adding capacity as fast as it can. For 15 years, U.S. electricity demand barely grew. Today, grid planners expect 166 gigawatts of new demand by 2030. While data centers are more than half of it, manufacturers and commercial customers have the same challenge. They need power faster than the grid can deliver. Storage helps close that gap. Every grid connection at a gas plant, a solar farm, a substation, a steel mill or a factory has hours when it runs below its capacity. Storage puts that power to work faster than waiting for new generation or transmission. Second, where battery is made is now part of a project financing model. Under the foreign entity rules that took effect in January, a project's tax credit depends on how much of its cost traces back to prohibited foreign suppliers, and the cell is about half of that requirement. Every system we shipped this quarter used Eos made batteries and cells with more than 90% American materials. That's what we mean when we say America's battery. Third, reliable performance decides who wins, and it has 2 key parts. First is delivery. A system delivered late can push a project past its tax credit deadline or delay system revenue. That's why we're consolidating operations into Thorn Hill, one factory running at scale at lower cost. And it's already working. Cost per cube came down again and margins improved for the eighth consecutive quarter. The second is performance in the field. Our system is a 20-plus year asset, and owners are using its flexibility to do more and meet new demand requirements. The same system might run a short cycle in the morning and a long discharge at night. Other systems today are built for 2 to 4 hours. Longer, more flexible duty cycles need a different design, and that's where Eos competes. Our installed fleet runs from 2 hours to 14. We now have 12 sites operating or in commissioning, up from 7 a year ago. More than half of our pipeline is 8 hours or longer, and recent deals include a new 10-hour project in West Virginia for Google. I've worked through several booms and busts in this industry. The winners were never the companies with the best technology on paper. They were the ones whose equipment showed up on schedule, resolved issues and then ran year after year, day after day. Customers and shareholders are asking us for the same, be reliable. Now let's look at fleet performance on the next page. Across our installed base, Eos systems have discharged 6.9 gigawatt hours over 4 million cycles, nearly a gigawatt hour of that from the Z3 fleet. Z3 round-trip efficiency averaged 79% on a full cycle, up from 78% last quarter, and that includes systems not yet operating on DawnOS. We didn't get here in a straight line, and the biggest lesson is at the bottom of this page. In our early systems, we controlled each cube as one unit. So a weak module set the performance of the whole cube. We changed how we control the system from 1 control point per cube to 3 to 6 to 168. DawnOS manages each of the 672 modules on its own, tracking its state of charge and state of health in real time. No single module holds back system performance. And with the improvements that John will talk about in operations, modules going out have a much smaller deviation or distribution of how they perform. The industry standard is to plan for capacity losses and add batteries over time to recover. We manage every module so the system holds performance, and we see a module that needs service before it impacts the system's output. And because we know exactly what's installed at every site down to the module, down to the software version, down to the firmware and improvement implemented in one site can be rolled out everywhere else it applies. The steepest learning curve for the company wasn't the battery itself. It was the system, the battery plus power electronics, the controls and the grid working as one. Our early Z3 projects took longer to commission than we planned, and we learned from each project and improved our fleet performance. Now let's go and look at a specific customer use case. Here on Slide 6, we are showing what the DawnOS architecture makes possible. New loads coming on to the grid aren't just large. They're dynamic. An AI training cluster can swing tens of megawatts in under a second over and over and over again. And arc furnaces and large industrial processes do the same. I spent much of my career around turbines, and I know the risk. Swings like that wear on turbine generator shafts over time. Regulators are seeing it, too. FERC has directed NERC to write mandatory standards for these loads by year-end, and grid operators are proposing ramp rate limits. Here, we are showing how an Indensity core absorbs the swing within milliseconds, and the grid sees a fraction of those swings and the utility sees a steady customer, not a volatile one. The questions that customer asks is what does that do to the battery itself? Fast swings create heat and heat is what wears traditional batteries out. We ran 2 Indensity cores available for customers today, charging and discharging into each other on a fast fluctuation profile for 147 straight cycles for over 735 hours. We saw no added temperature rise and the round-trip efficiency held at 81%. Indensity runs the same module level controls we just covered on the previous slide. We're continuing to test and are using this data to show customers our operating flexibility. One asset can do both jobs, smooth the load milliseconds and shift energy over hours. For the customer, that's a faster path to power. For the utility, that becomes system reliability. For the community, that's growth without higher electricity bills. That's what we mean by assets that meet today's grid requirements. Turning to Slide 7. Let's go into some details on the backlog. We ended the quarter at $765 million, about 3.2 gigawatt hours. That's up 19% from a year ago and down from $807 million in Q2. We shipped more than we booked last quarter. This is project timing, not a fundamental change in demand. We're currently working 3.5 gigawatt hours of late-stage opportunity more than today's entire backlog. More than half is waiting on financing, the rest is in contract negotiations. Our pipeline reflects where the market is moving, longer duration storage, growth across multiple end markets and stand-alone projects that will make existing energy infrastructure more efficient. While Frontier Power USA is now about 43% of the backlog, we're also widening the customer base. We closed orders with 6 customers, 4 of them new last quarter. We don't expect every late-stage opportunity to close and the NYSERDA bulk storage program is a good example. One of several state programs we are pursuing. No Eos projects were selected in the first round that awarded less than 1/3 of the program's 3 gigawatt target. Those projects can reapply for the next round, which is expected by the end of this year. Focusing now on the middle of the slide, you see why the capabilities on the previous page are so important. The biggest driver of storage economics isn't round-trip efficiency. It's how many cycles a day can you run to generate revenue. Adding just half a cycle per day reduces lifetime storage cost by approximately 10x more than a 5-point round trip efficiency improvement. On top of that, the intrinsically lower operating cost of an Eos Indensity system further increases project returns. Policy at the state and federal level is making long duration a critical requirement with a growing number of states setting procurement targets with defined duration mandates. California is soliciting up to 2 gigawatts of 12-hour and multi-day storage, while Massachusetts has launched a 5,000-megawatt energy storage program for projects with durations of 4 hours or longer, including dedicated longer-duration storage tranches. And in PJM, Virginia passed one of the largest storage mandates in the country this spring, calling for approximately 21 gigawatts by 2045. The market is requiring American-made long-duration energy storage. We must turn more of our pipeline into backlog, and that's where Michelle and the team are focused. With that, I'd like to turn it over to John to walk through operations, including our progress at consolidating into Thorn Hill.
