Joining me on this call today is Robert Piconi, our Chairman and Chief Executive Officer. At this time, I’d like to hand the call over to Robert.

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: Michael, thank you. I’d like to welcome everybody. Good afternoon, evening, and morning. I want to call out up front as well, the investor presentation that hopefully all of you by standard course download. It is on the website and would be great if you are listening in here to download that. I will be referring to some of the charts in that deck, in particular pages 4 through 9. Very interestingly, hopefully if you’ve noticed, we are providing even more transparency with some of the data, in particular as we have made this transition now to an integrated storage IPP. We’ll be providing some more details in and around backlog, for example, and even looking at our comparable companies in what we’re considering as a new peer set as we’ve made this transition.

If you’ve seen the results by now, hopefully you’ll agree that this is a very strong validation of our shift into an energy infrastructure platform provider, more than doubling our MW capacity under management from last quarter to over 1 GW. The new project acquisitions that make that up as designed will ensure long-term, high margin, and recurring revenue streams, as reflected in the strong contract backlog growth that, as you see, is over $1.3 billion, made up primarily of our own and operate projects now, projects that are pre-funded through our existing Asset Vault platform. We also see strong near-term demand growth for our AI compute infrastructure solutions, integrating storage, generation, and under our unified software control.

That strong historical execution capability, and I know I’ve talked about that a few times here, in particular in the last year, as we’ve delivered revenue, and in particular in Q4, delivering over $150 million, we have earned this right with our customers. That’s enabling interim revenue upside potential while our larger scale own and operate projects are being constructed and coming online in the coming 12, 24, and 36 months. With the move squarely now into the IPP and digital infrastructure company peer groups, as reflected by our current contracted backlog, and you can refer to page 9, as we look at this, we do believe a re-rating here is gonna help the valuation and the related upside to our current trading. Over the past 12 months, we have transitioned from a project-based provider into a fully integrated power and AI infrastructure platform.

As we can see by the results in the execution and scaling of our own and operate model, the quarter demonstrates that acceleration. This is no longer a forward-looking transition. It is now visible across our backlog, our asset base, and our financial performance. In particular, it will, as it did last year as we get into the latter half of the year, as revenue again scales. We’re providing an integrated energy and power infrastructure platform that’s bringing together, as a reminder, not only energy storage, but also now generation components and, as always, our intelligent software platform that from design, from the inception, was designed to handle any generation tech, whether that be gas or renewable, as well as any and all storage technologies to solve one of the most pressing challenges in the global economy today, and that’s delivering reliable power quickly and at scale.

We integrate these capabilities and capital structures to build, own, and operate, and in particular, as a vertically integrated IPP. What that means is we can be faster, we can be more cost-effective, as our growth margins are showing and demonstrating at about 2x the market, and that comes from less friction, and less friction in terms of cost and time, and at the end delivers higher quality. We’re achieving over 99% uptime across every one of our storage projects that are operating today. We do this now and are solving what is the primary constraint across global markets, and that is access to power. The most important takeaway for us this quarter is we’re accelerating that execution now of our own and operate model. You can see that in three areas, as well as many other details that we’re gonna be providing on the call.

Our portfolio now exceeds 1 GW of assets under control that’s contracted, under construction or already operating. Our backlog has grown to over $1.35 billion, over 80% of that, as you’ll see, is tied to owned assets now, which is a shift if we go back just a short 4-5 quarters. We now have visibility to over $180 million in our recurring EBITDA run rate, which is ahead of our plan, also reflecting the inclusion now of powered land and powered shell opportunities where we are owning assets and providing power. This has obviously reflected a shift from a more episodic project revenue to predictable long-term infrastructure cash flows.

Importantly, we are executing ahead of that plan, as I’ve just mentioned, and a lot of that’s due to some of the dynamics we’re seeing now in the AI infrastructure compute space. If you look at page 4, which we provided, which looks back from our Q4 2024 actual, looks at our revenue and our backlog and shows what that looked like at the end of 2025. Growing that backlog from about $400 million to $1.3 billion today. As well, it looks at our gross margin, which has improved from 13.5%, just 6 quarters ago, to almost 24% at the end of 2025, and projecting close to 25% for this year.

I would say that if you look at the backward-looking view, we have executed now the strategy and are now, if you look at our backlog, at 80% own and operate, we’re there. At the same time, as highlighted therefore in the press release, we’ve got some, and if you turn to slide 5, we delivered broad-based triple-digit growth across most all key metrics. Revenue up over 150% year-over-year. Backlog more than doubled, 108%. Adjusted gross profit up 25%. Cash up 148%, reaching $117 million. And our megawatts, very importantly, under our control, up almost 5 times year-over-year and already more than doubled to 140% sequentially.

Every core metric, all of these capacity backlog revenue and our liquidity is fulfilling what we’ve outlined and what we demonstrated with our strategic shift from 2 years ago. If you look at slide 6, we’ve added this look at our backlog to take a look at where we’ve transitioned in just the last 6 quarters. What you see is a shift from what has historically been our energy storage EPC revenue, looking at our current backlog at $1.35 billion, towards primarily the long-term own and operate revenue streams. Importantly, the gross margins associated with that backlogs will be fundamentally shifting as we build these projects and bring them online over the next 12, 24, and 36 months. Those margins shifting from the 20%-25% range up to the 60%-80% range for IPP level margins.

A lot of the growth that we’re seeing, both in terms of the initial megawatts we’ve been adding, but as well as what we will be adding more in the future, is related to the AI data center space as well. That’s powering a lot of the infrastructure investments, in particular in the U.S. Power availability is now the gating factor for expansion. We’ve added 100 MW of powered land and powered shell just this quarter. That alone is gonna be expected to generate $65 million in recurring EBITDA in the next 12-18 months as that comes online. Beyond the primary power capacity, we’re addressing resilience needs through energy storage systems that we deliver and operate. If you go to page 7, just a reminder of that unit economics growth that I just described from that backlog.

You can see how that works relative to our core standalone storage there at the bottom of the metric, and then moving up to our powered land and powered shell, as well as the geographic expansion. The addition of the powered land and powered shell for AI is what’s helping drive our acceleration. Very importantly, I think as you move to page 8 as well, you can see that we’re expanding where we’re gonna be going, not only as we look at this quarter, you see expanded from 440 MW to over 1 GW, as I mentioned previously.

Looking out over the years, we’re also increasing where we’re going and what we’re gonna have under management by 2030, reaching almost 4 GW as we look at today and what we see in our funnels and our development pipeline and what we’re executing that’s underneath our control already. You can see the EBITDA numbers there in those outer years get very large, and a lot of that work to achieve that is underway now as we’re building and constructing these systems that are gonna come online over the next 2-3 years. I want to finish here, if you look at slide 9, it highlights how the market is beginning to reframe Energy Vault, not as a traditional storage company, but as a broader power infrastructure platform.

This evolution is critical as we expand into owning and operating integrated energy assets, particularly in support of the AI data center and digital infrastructure. I mentioned this before, but not all megawatts are valued the same, and hence our move into the AI digital infrastructure space is accelerating what we’re gonna be delivering in our initial targets. We’re moving into a category that commands structurally higher valuation multiples. The infrastructure platforms with predictable long duration cash flows and low revenue volatility are valued differently from project-based businesses, and this shift is increasingly reflected in how investors benchmark this sector. Importantly, this repositioning supports a meaningful re-rating opportunity. As we execute and continue to execute against our megawatt pipeline and bring assets under ownership control, we unlock the full value of the long-term contracted EBITDA streams. Successful execution of megawatts under control is the bridge to this value realization.

I mention again that strong historical execution capabilities have earned us this right with our existing customers who want to work with us on new projects, but also enabling this interim revenue upside while our larger scale projects are being constructed and coming online. With this transition, we’re firmly into the IPP and digital infrastructure peer groups, reflected in our contracted backlog now at about 80%. We believe this evolution is going to support the re-rating and some meaningful upside to our current trading levels. If you look at that chart, you’ll see how we’ve historically looked at our comp companies in there and looked at the performance, both the year to date this year, as well as the trailing 12 months.

You can see we’ve had a very, very strong appreciation of the stock price, if you go back 1 year ago, but also this year now into our current trading. I think most importantly, if you look at some of the new trading comps in the mid part of the page there and look at the valuation multiples there on the right, you’ll see the opportunity that, of course, we’ve seen and why we made the strategic shift back 2 years ago. To close, before I turn it over to Michael, who’s going to get into some of the details of our results for the quarter. We’re accelerating the execution of our own and operate strategy. I think this big increase in the uptick in the megawatts under our management is a strong reflection of that.

We’re also scaling a globally diversified infrastructure platform, now over one gigawatt. I think that’s important because things regionally can change. We saw that with the tariff environment, just one year ago. There was a lot of uncertainty. Having the exposure to markets like Australia, for example, and our recent acquisition of a large portfolio, 850 MW in Japan, with 350 MW of near-term projects there, reflect the fact that we are expanding in the most attractive markets and will give us that global diversity despite the fact that we see tremendous and large opportunity, and probably the largest opportunity right here at home in the U.S. Energy Vault today isn’t just participating in this transition, we are building the infrastructure backbone that enables it across the energy and power side, AI, and the industrial markets.

I also want to mention and thank the Energy Vault team for their dedication, their passion, their commitment to executing our strategy here every day. I think the results here are a reflection of this, our reiteration of where we’re going to be this year and the guidance we just set six weeks ago. We feel very, very good about executing and a lot of upside we believe that exists within that guidance range. With that, I’ll turn it over to Michael Beer.

Michael Beer, Chief Financial Officer, Energy Vault: Thanks, Rob. As you can see in the financial summary on slide 18, we delivered Q1 revenue of $21.9 million, representing a 156% increase year-over-year, driven by higher energy storage project deliveries and initial contributions from assets within our Asset Vault portfolio. Adjusted gross profit for the quarter was $6.1 million, up 25% year-over-year, with an adjusted gross margin of 27.9%. Adjusted gross profit reflects the removal of Asset Vault operating project-related depreciation and amortization as those projects commenced operations in mid-2025. The prior year gross margin of 57.1% was highly skewed by IP-related revenue.

Adjusted EBITDA was negative $13.6 million in the period, compared to negative $11.3 million in the prior year period, reflecting continued investments in our own and operate strategy, including development expense and organizational scaling to support long-term growth. Excluding one-time impacts from the extinguishment of debt and stock-based comp, Q1 2026 adjusted net income of negative $20 million compared to negative $11.8 million in the prior year period, due to higher D&A and personnel from the new O&O Asset Vault projects and associated project-related financing expense and interest. From a cash position and financing perspective, we ended the quarter with $117.1 million in total cash and cash equivalents, reflecting continued investment in our Asset Vault portfolio alongside strengthening financing activities.

As Rob mentioned, during the quarter, we significantly enhanced our balance sheet through the successful completion of a $150 million convertible senior notes offering, which was upsized from $125 million. A portion of the proceeds was used to repay $45 million in higher cost debt while also implementing a capped call structure within an implied conversion price of $8.12 per share. In addition, we began monetizing investment tax credits, completing approximately $12 million of net ITC transfers with approximately $40 million in total ITC proceeds expected across all projects placed in service thus far. These actions collectively strengthen our liquidity position and provide the financing flexibility to accelerate execution of our global asset ownership strategy.

At the project level, management is in the market for the SOSA and Stoney Creek project financings, which we expect to complete this quarter and in the second half of 2026, respectively. We’re also evaluating a number of other financing opportunities, including those in support of our ramp in Japan and surrounding the powered land space. Turning to our latest backlog and development pipeline on slide 17. We exited the quarter with a record backlog of $1.35 billion, representing 108% year-over-year growth, with over 80% associated with our own and operate portfolio across the U.S. and Australia. This backlog provides strong multiyear revenue visibility and reflects continued traction in converting our developed pipeline into contracted projects. From a commercial activity standpoint, we made meaningful progress expanding our global footprint and asset base.

One, we advanced our U.S. portfolio with the acquisition of the 175 MW, 350 MWh McMurtre BESS project in Texas. Two, we announced entry into the Japan market, including the 850 MW development portfolio with 350 MW in advanced stage projects expected to close this quarter. Three, we have added a number of smaller projects in Switzerland and made headway with the opportunity in the Balkans. Four, we continue scaling our AI power infrastructure platform, including progress on the 75 MW powered land opportunity, where a number of agreements have now been secured. Across our platform, total megawatts under control in construction or in operation now exceed 1 GW, supporting a growing base of long-term recurring revenue opportunities.

From a developed pipeline perspective, which we now view on a megawatt basis versus megawatt hour, we are now actively progressing opportunities valued at $3.5 billion, associated with over 3.5 gigawatts. Taken together, our advanced developed pipeline and contracted backlog provide strong visibility into the next phase of growth for the company. As we continue executing our strategy, we are seeing clear validation of our transition towards a vertically integrated build, own and operate model. Our global asset portfolio now exceeds 1 gigawatt and is expected to generate over $180 million in annual recurring EBITDA run rate ahead of prior expectations. This positions us to deliver increasing levels of predictable, high quality earnings as assets move into operation.

Turning to our business outlook for 2026, we are reaffirming our full year 2026 guidance, including revenue in the range of $225 million-$300 million, with approximately $75 million-$100 million in internal Asset Vault project builds. Gross margin of 15%-25% and year-end cash in the range of $150 million-$200 million. This outlook reflects continued execution across our backlog, scaling contributions from owned and operated assets and disciplined capital deployment. With that, I’ll hand it back over to you, Rob.

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: Great, Michael. Thank you. I think with that, we’ll turn over to the operator for any questions.

Operator: The first question comes from the line of Justin Clare with Roth Capital Partners. Please go ahead.

Justin Clare, Analyst, Roth Capital Partners: Hi. Thanks for taking our question and, congrats on the growth in the backlog here.

Michael Beer, Chief Financial Officer, Energy Vault: Hey, thanks, Justin.

Justin Clare, Analyst, Roth Capital Partners: Wanted to just start out on the AI infrastructure here and the 100 MW of powered shell and powered land that you plan to complete over the next 12-18 months. Wondering if you can just share more on the status of those projects. For example, you know, how much of the 100 MW is contracted and has offtake versus how much is in negotiation? What’s the interconnection status? Where are you in terms of permitting those projects as well?

Michael Beer, Chief Financial Officer, Energy Vault: Okay, thanks. We have announced 100 megawatts there in powered land and powered shell, as you know. I think at our last earnings, we mentioned publicly the Southwest utility for the 75 megawatt of powered land, that also is under a load study for application for 925 additional megawatts for a total of 1 gigawatt. That’s in the phase right now of the first 75 megawatt is already in construction and committed, and it’s gonna be coming online in January. Okay? As far as the powered land goes, from the powered shell perspective, we have our already announced agreement with Crusoe that’s under now that development, and we have the, all the sites and all the load ready for that, and that’s gonna be constructed.

As we said before, that’ll start to come online in Q4 this year. That’s where we are as far as the powered land and the powered shell, I think most of those, as we look at the opportunities that we’re developing, is where you’re gonna expect to see some significant growth. If you looked at the, on, I think it’s page 8 of the deck, you’ll see, in fact, that mix shift. You’ll see the mix of powered land and powered shell versus our standalone storage. You see it increasing significantly there between where we are today in March 2026 up through 2030. You can see that that’s gonna move from roughly about 10% of that megawatt funnel to a little over half of it over the next few years.

I would expect that you’ll be seeing, and you can expect to be seeing more announcements in that space.

Justin Clare, Analyst, Roth Capital Partners: Great. Okay, appreciate the detail there. On the $180 million of recurring EBITDA that is anticipated when you build out the backlog here, wondering what the timing of that is and how that ramps over the next, you know, two to three years or so. Wondering on the $180, if you could also break down how much of that may be related to BESS projects versus how much is powered land and powered shell.

Michael Beer, Chief Financial Officer, Energy Vault: Sure, happy to comment. We previously gave guidance in November of last year around the overall size of the Asset Vault portfolio. We had initially talked about that being sort of a target of $150 million of recurring EBITDA. We’ve since announced our entry into Japan. We believe Japan is a 350 MW sort of attractive late-stage portfolio. That would be in addition to that initial guidance. Now we’ve given more fidelity around what we believe the contribution would be from powered land and powered shell on the order of about $65 million in recurring EBITDA. If you were to take the 150, remove the 65 from powered land and powered shell, obviously the increase beyond that is associated with the Japan portfolio.

This is sort of envisioned to be in that sort of, let’s call it, circa 2028, early 2029 type timeframe.

Justin Clare, Analyst, Roth Capital Partners: Yeah.

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: Yeah, Justin, I’d also.

Justin Clare, Analyst, Roth Capital Partners: Okay. Very helpful.

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: Yep. Just to add to that too, there’s some good charts we’ve included in the deck that reference that, the one on the unit economics. The reason we’re seeing this acceleration is, as we met almost a year ago, we looked at a lot of the storage, the standalone storage IPP. As we’ve evolved the last 12 months and looked at the AI compute infrastructure space, those deals and those megawatts that we’re contracting and owning are delivering anywhere from 5 to 10x the EBITDA contribution per megawatt per year. That’s why we’re providing some of the breakdown around what that mix shift of these megawatts is gonna look like.

As we add more of those, you obviously can expect, you know, continual acceleration in terms of hitting and just growing that annualized recurring EBITDA number with it. If you look at the chart on page 8, you’ll see where we expect that to go as we’ve increased that just from the last quarter.

Justin Clare, Analyst, Roth Capital Partners: Okay. Got it. Thank you. I’ll pass it on.

Operator: Thank you. Next question comes from the line of Derek Soderberg with Cantor Fitzgerald. Please go ahead.

Derek Soderberg, Analyst, Cantor Fitzgerald: Hey, guys. Thanks for taking the questions. First one on gross margins here. Guidance looks like 15%-25% for the year. Just kind of thinking about that range, what are some of the variables, maybe it’s battery cell pricing, maybe some project mix, what sort of variables are gonna determine where you guys sort of land in that range? Maybe as of today, where do you think you’re sort of tracking towards that range? Maybe the lower end, the higher end. Maybe talk about that. Thanks.

Michael Beer, Chief Financial Officer, Energy Vault: You can see quarter to quarter there can be some different, you know, mix components. Even, you know, a year ago we had some significant IP-related contributions, so we had a 57% gross margin. This quarter, on an adjusted basis it’s about 28%. On a GAAP basis it’s about 22%. You know, obviously we’re tracking to be better than the midpoint of guidance. You will have a very back-end loaded sort of revenue year associated with project deliveries, right? We still are in the EPC business, the fourth quarter will be heavily influenced with some of those deliveries. Those deliveries can generally, you know, obviously balance out the overall shape of the year and the total gross margin profile. Still feel very confident around the overall range.

Obviously, we endeavor to do better than the midpoint, just as we had done last year.

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: Derek, the other thing just to add to that is our new gross margins now and revenue that’s going to include the storage IPP is also just from a GAAP perspective, is going to include the non-cash portions of depreciation. That’s why we’re referring, and this will make the comparisons good from last year to this year, our adjusted gross margin, which is really getting at that cash gross margin only without the IPP revenue, so you can really compare apples to apples as you look at the EPC revenue. If you do it that way, for example, we’re closer to, I think it’s 27.8%, 27.9% this quarter. We intend to focus on execution, on managing our supply chain.

As we’ve done the last quarter, we obviously continue to be setting ranges that we know and feel comfortable we can hit, and we’ll push execution to remain on that upside.

Derek Soderberg, Analyst, Cantor Fitzgerald: Got it. That’s helpful. As my follow-up sort of related to the first set of questions. The first 75 MW on the powered land piece coming online in January of 2027 and then the 25 MW coming online in Q4 of this year, I was wondering if you could sort of maybe provide some detail on how that revenue’s gonna scale, how that EBITDA is gonna scale, anything around that. Also just on that opportunity to potentially go up to 1 GW on, you know, that sort of higher EBITDA, you know, per MW opportunity. Can you talk about what sort of milestones you need to hit before that larger opportunity starts to materialize? Thanks.

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: Sure. I’ll hit both of those, Michael can chime in as well. To the first question on, you know, both the 75 MW and the 25 MW. The 75 MW is committed to be online in January, as I mentioned. That full 75 MW will be online. Essentially, the switch is getting put in place. There’s some transmission that’s being built out. That is already underway. We already have made payments toward that to happen and committed. What you would see on that is an offtake agreement of that 75 MW. Once that turns on in January, you can expect that to be fully monetized, meaning we will be in a contract and monetizing that. We should get almost a full year of EBITDA there, of that 75 MW.

It’s, you know, estimated at somewhere in and around $35 million. That’s the 75. On the 25, just to be clear, we’re gonna be starting those deliveries, meaning we’re gonna start to receive and have those systems come on within Q4. Not all 25 megawatt will be in Q4, will, as we’ve said, will come in the next 12 to 18 months. Meaning we’ll be beginning to receive and activate the powered shells and be installing those in the forward quarters from there. That’s helpful. The good news about that is we expect in the next 12 to 18 months to have that roughly $65 million, you know, up and going on an annualized run rate basis.

The second part of your question on the 75 going to a gigawatt. There is a study that’s already underway that we’re engaged with the Southwest Utility. That study is looking at the addition of 920 MW to that 75, so that would be up to a full gigawatt. Those are large numbers. You know, you can do the math on just what that 75 is, as I said, and scale that. We do expect somewhere in and around half a million or so per MW on that. That’s a study that’s going to happen, that’s happening now. There will be some decisions, I think made then this year.

We expect in the next 3 to 6 months on also some sizing of what the capacity upgrade will be. That’s essentially gonna be all the transmission and high voltage equipment that will be required to bring that 925 MW here to market. That will be coming in place over the next, you know, 24, 36, 48 months. We are expecting, just to be clear on that, we are expecting to look at doing an interim step with some other generation equipment that we would couple with our storage, for example, to try to bring online something on an interim basis of another 225 MW to potentially add to that 75. This is within this core powered land segment.

That would be an interim step to get a solution in place. Obviously, as we’ve said before, with a hyperscaler, that’s in a very attractive location that we’ll be sharing more of as we do some formal announcements, namely utility, et cetera, and other things this year. From a timeline perspective, just to summarize, the 75 MW in January. Following that, within the next 18-24 months, we’re looking at another 225 MW to bring online on an interim basis until that other 925 MW of grid power would come online in the next 36 months plus. Appreciate the detail on that. Thanks, guys. Yeah. Thank you, Derek.

Operator: Thank you. Next question comes from the line of Brian Lee with Goldman Sachs. Please go ahead.

Tyler Besson, Analyst (on behalf of Brian Lee), Goldman Sachs: Hey, guys. This is Tyler Besson for Brian. Thanks for taking our questions. Just first wanted to touch on the margins in terms of the backlog. What is the timeline to reach these 60%-80% IPP margins as you execute on the backlog? Just to confirm, this would be on an adjusted basis.

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: Yeah. There’s obviously two distinct margin profiles for each of the different businesses. You know, the 20%-25% is akin to the legacy, let’s call it EPC-related business. The transition to the IPP business model, those 60%-80% IPP margins, you can see that all laid out on, I believe it’s slide 6. Obviously, there’s going to be a mix effect that will take place over time, right? As these projects come online. We’re not exiting the EPC business. We’ll continue to do that, not only for third-party customers, but we self-perform these projects for ourselves, and there’s actually a positive working capital function that serves. We’ll continue to be in that business. It’ll be a blending over time. It won’t just be a flip of a switch.

Tyler Besson, Analyst (on behalf of Brian Lee), Goldman Sachs: Helpful. Can you provide an update on just, you know, your revenue trajectory for the balance of the year? Noticed accounts receivable stepped down a quarter. Could you see 2Q revenues decreasing quarter-over-quarter? You know, how are you thinking about the balance of the year from a revenue standpoint?

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: Yeah. We generally don’t give sort of quarterly guidance in that respect, but as mentioned, it will be a back-end loaded year. I would use a profile akin to what you had seen last year. As you saw there, just to add to that, we have very strong year-over-year compares just given we are projecting over 30% growth at the midpoint here. You know, if you look at the trajectory, as Michael said, and look at that framework, we are expecting something similar there and generally, I think if you look at the year-over-year compares, we’re still gonna be pretty favorable, I think as we ramp and scale.

Tyler Besson, Analyst (on behalf of Brian Lee), Goldman Sachs: Understood. Just one more from me. Can you just provide some more details on the progress on the developed pipeline and backlog? Looks like developed pipeline increased to 3.2 GW from 1.8 GW last quarter, but the value went up to $3.5 billion from $3 billion. On the backlog, it looks like it remained flat at 3 GWh, but the value went up slightly. Can you just discuss some of the moving pieces here?

Michael Beer, Chief Financial Officer, Energy Vault: Yeah. There’s always a bunch of ins and outs, FX. There’s a host of things that can sort of move these things at the margin. I think within developed pipeline, interestingly, we’re starting to see some real benefits of this integrated model and the fact that sort of one hand washes the other. While we are in both the EPC business and the IPP business, we’re now starting to see some opportunities emerge that sort of split the difference or are emerging from both camps. So the fact that we do have a team focused on both sides of the business is being, you know, very additive in that respect. So we’re seeing new projects being added all the time.

We also cull our developed pipeline to make sure that if things are stale or if projects have moved on or, you know, for whatever reason. We try to keep this very current and not make sure it’s stale. I think this does represent the current slate of investments that we have here in the U.S. across multiple, sort of industry sub-segments. And geographically, we’re seeing some other things emerge internationally.

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: The other perspective I’d share with you here, and this is an important one, it’s something that we looked at as we made the decision 2 years ago to focus on owning and operating. That means we’re acquiring megawatts. We’re gonna be building them, the revenue doesn’t come during that build, right? It doesn’t come until we actually go COD or we go online with the project. You would have normally expected, if we’re really making that shift, you might have expected our revenue, our rev rec, actually going down over a period, right? 12-24 months as you make the transition.

What we challenged the team with here and what we targeted to do was, despite the shift we’ve made from owning and operating assets where we are not recognizing revenue, even though the activity is much more than even our projected revenue is showing because we have activity that we don’t recognize. We are building projects. Energy Vault is building projects for Asset Vault that is not showing up in recognized revenue. We have more activity than we’ve ever had. The challenge was: how do we keep revenue growth, meaning recognized revenue, going until these new projects come online?

What I feel very good about with the team and the execution, is that we were able to still have a year, this year in 2026, with strong double-digit revenue growth, despite the fact that as you see in the megawatts that are growing to now over 1 gigawatt that we have under our control and management and building out, that we are not recognizing revenue on that. Despite that, we’re still seeing that revenue growth.

That’s a lot of that’s driven, I think, in the U.S. market in particular with what’s happening with the AI infrastructure and, in particular, these power packages that are getting put together where we’re looking at and we are doing and integrating our energy storage with generation, with gas generation, for example, but also with UPS backups that are a part of those and coupled with that gas generation. Then we’re integrating that solution across a single pane of glass, meaning a single software platform to bring that all together for a customer. Those are solutions that we actually do sell and turn over. That is allows us to do the revenue recognition in parallel.

This, the whole AI compute infrastructure and the, you know, the $ billions and, you know, arguably it takes $ trillions over time that’s going to be spent for that is enabling us to maintain this revenue growth with that focus on these solutions. A lot of that has come from customers that know us, that trust us, where we’ve executed for. They have their systems up and running, you know, at 99% plus availability. We feel not only good about that in the revenue projections we’ve done this year for growth, but we do see a lot of upside to the current revenue projections for that growth as well.

Tyler Besson, Analyst (on behalf of Brian Lee), Goldman Sachs: All right. Thank you very much. I’ll turn it over.

Operator: Thank you. Next question comes from the line of Siddharth Rengachari with Fundamental Research Corp. Please go ahead.

Siddharth Rengachari, Analyst, Fundamental Research Corp: Hi. Congratulations on the strong results. How are Calistoga and Cross Trails operations performing, given it’s been almost 12 months since both started operating? Are revenue and margins there in line with your expectations?

Michael Beer, Chief Financial Officer, Energy Vault: Yeah. The Cross Trails project continues to perform well. There hasn’t been a change and, you know, we’re expecting, you know, on the order of, circa $10 million in EBITDA on a full year basis.

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: Yeah. I’d add to that-

Michael Beer, Chief Financial Officer, Energy Vault: Across CRC and then Cross Trails. Yeah.

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: I’d add to that too, as we all know, I think in the IPP market, ERCOT obviously is undergoing and has been really the last 12, 18 months, really almost the last 2 years, you know, weakness at least on a cyclical basis versus the prior years. I think we’re seeing that. You know, the good news about our system there in ERCOT is it’s been running at a 99% availability despite that. Obviously we’ll take advantage of opportunities when they come. It is that sort of softness in the ERCOT market has made it a buyer’s market when we’re looking at acquiring megawatts. Therein lies some opportunity.

We’ve been very, very careful with selecting the best points of interconnect, and doing a lot of diligence there to have the, you know, the points of interconnect, as is the case with McMurtre that we announced, that’s just north of Dallas there in Texas. At points where we do believe we can leverage good economics.

Siddharth Rengachari, Analyst, Fundamental Research Corp: Great. Thank you for that. With the ownership structure of the Japanese initiative, will that be similar to your other assets, given you’re partnering with the local developer there?

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: Yes. We were expecting, and I think we mentioned this in the when we made the announcement. The Japanese market is fascinating because if you go back and look at where ERCOT was four to five years ago, we see the Japanese market just evolving now in that same type of economic environment and opportunity therefore to initially deploy and take advantage of a lot of the frequency and some of the other ancillary services and even the arbitrage opportunity there in Japan. In terms of structurally, that initial team that we’re acquiring, that it was from an existing large company there. That team is gonna be the one that’s gonna be continuing developing those near-term projects.

Of the 850 MW that are within that portfolio, there’s 350 MW of near-term projects that, as we said in our announcement, we expect this quarter to close on that 350 MW and then get those constructed and get those up and operating. I think from a, from an overall structure, in terms of how we look at debt and equity and financing these, I would say it’s, it would be unlike as we’re looking at projects in the U.S. and Australia.

I think one of the differences there, Michael can comment on this too, is you have a very favorable interest rate environment, I think in Japan, that is gonna be helpful relative to the financing and their very known project financing models as well.

Michael Beer, Chief Financial Officer, Energy Vault: Yeah. It’s an existing team that we’re technically acqui-hiring with a very robust portfolio. You know, as we mentioned in the some of the prepared remarks, we are gonna be going to market from a financing perspective in support of host of those projects. You know, the fact of the matter is we entered the Australia market just a few short years ago and look at the amount of traction that we’ve been able to sort of generate there. You know, we’re looking to replicate that in the Japanese market.

Siddharth Rengachari, Analyst, Fundamental Research Corp: Any comments on the offtake pricing you can get there? Is the ROI, would you say it’s comparable to the U.S. or higher?

Michael Beer, Chief Financial Officer, Energy Vault: I don’t believe we’ve given real specifics there. It is an attractive market, but obviously we feel as if we’re early to that market and, you know, obviously we’re putting our money where our mouth is. But we haven’t given any of those specifics.

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: We’re expecting.

Siddharth Rengachari, Analyst, Fundamental Research Corp: Thank you so much.

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: I think. Yeah. I was just gonna add I wouldn’t think that it’s gonna be far off from what our expectations are on achieving IRRs, sort of low double-digit type of IRRs, as we get started there and an opportunity for optimization on that. Hence our investment there. It is what we believe that is today and will continue to be in the coming years an attractive market.

Siddharth Rengachari, Analyst, Fundamental Research Corp: Appreciate the color. Thank you.

Operator: Thank you. Next question comes from the line of Noel Parks with Tuohy Brothers. Please go ahead.

Noel Parks, Analyst, Tuohy Brothers: Hi, good afternoon. You know, one thing you were mentioning gas generation a moment ago, and sort of in the landscape of potential business out there for your pipeline, I guess I’m wondering maybe what’s the main pain point for potential customers. I guess I’m thinking about whether there’s any difference between those where they’re looking, say, for new AI-related generation, where gas generation is probably gonna be at the core of it, versus situations more where it’s, you know, a case of playing catch up with wind and solar for grid integration. I guess is one of those a much bigger driver than the other, would you say?

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: Yeah. I’ll Noel, it’s a good question. The reason you’re hearing more and more about gas is just 2 things. Obviously, the power demand largely outstrips the supply or the ability to deliver it. That’s one. Any and all solutions, you know, solar, wind, combined with other types of generation and leveraging. We have, you know, obviously abundant natural gas in the U.S. I think gas is gonna play an important component in particular over the next 3-5 years plus. In addition, remember what’s driving this are data centers, and the requirements are at five nines reliability. Which is, you know, if you’re thinking about that and thinking what that requires.

You know, it’s gonna be different regionally, but look at if you go back to an event, for example, in Texas, we all remember in the cold and the frost and the freeze, and that shut down things for a matter of days. With the requirements and SLAs at five nines reliability in AI compute infrastructure, you know, these are things that therefore require not only redundancy, but in some case there’s multiple redundancies. You can think about having a grid connection. Okay, everybody likes that. You can add energy storage to that, which will be good, you know, for if there’s an outage, you know, you can name it for some hours. Let’s say, and even up to the day.

If you get into a multi-day outage, that’s where looking at having some type of reciprocating engines or gas, diesel gen, et cetera. You can actually have a solution that when you put together, for example, grid power, plus energy storage, plus some gas power backup, you’ve got something where you can deliver on five nines. It’s, you know Hence, that’s the numbers you’re seeing, and that was that tremendous amount of CapEx in the data center build-outs. A lot of that’s, you know, a lot of that CapEx is also essentially guaranteeing that power availability and delivery. Does that make sense?

Noel Parks, Analyst, Tuohy Brothers: Yes, absolutely. You did touch a bit on it already, sort of the comparison of Japan to where ERCOT was a few years ago. I remember when you announced the Japan acquisition, you sort of stressed the importance of grid stability and load balancing in Japan, that they’re at that stage now. I just wonder if you could maybe just dig into that a little bit deeper and whether there are similar, you know, analogous regions that might be needing to deal with this sooner rather than later.

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: Yeah, I’d say that the perspectives we’ve shared from the announcement and what you’ve just articulated is what we see. As I mentioned, you know, we’re gonna see some of the fast frequency response, that load balancing, and I think opportunities to capture different types of pricings at different times of day. I think generally, that dynamic is gonna be positive, we believe, for the market, and I think others that have entered there recently are seeing the same thing. As far as other markets that have those same dynamics, there’s an important aspect to look at this, and I think Asia PAC’s a great example, where there are other markets that may have those same types of, you know, environmental factors.

The other thing we look at is scale and priority.

in terms of the markets we choose and not spreading ourselves too thin. There would be, you know, there are, I think, other markets that have those same characteristics and even in some newer European growth markets, for example, that we’re seeing. We’re very focused right now, I think, on some of the largest opportunities and focusing our capital investment, our human resource investment in the areas where we see the biggest upside. A lot of that, by the way, is right here at home in the U.S.

Noel Parks, Analyst, Tuohy Brothers: Right. Great. If I could just sort of run 1 more by you. I was thinking about the process of project financing over the last 2 years. You’ve seen this real transition from being able to get it, you know, much earlier in a project’s life cycle. I’m just wondering, as you’re going through your process of, you know, negotiating and arranging it for your upcoming projects. I’m just wondering, is there considerably less of an education burden that you have to address in terms of, you know, your counterparties and their due diligence? Is it essentially still just everyone needs to go through a pretty similar tire-kicking process?

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: Yeah. The market is evolving so quickly. You know, whereas nobody would have even looked at sort of merchant years ago, you know, now that’s being sort of incorporated into models, and people are getting very creative in how they structure, you know, bridges or construction financing sort of in and around sort of some of the IPCs. You know, the market is evolving very, very quickly. Certainly here in the U.S., we’re also seeing that bleed over into some of the other markets where we’re constructing assets such as Australia and what I suspect is likely Japan. We need to go through that process.

The fact of the matter is we’ve now done this a few times and we now know what we’re looking for as we’re evaluating project attractiveness and what can possibly go wrong. Just mitigating risk where possible, bringing partners into the fold earlier in the conversation, you know, and trying to build a good, let’s call it feedback loop of existing partners so that we can sort of rinse and repeat across the entire portfolio and just remove friction where possible.

Noel Parks, Analyst, Tuohy Brothers: Terrific. Good to hear. Thanks.

Operator: Thank you. Ladies and gentlemen, we have reached the end of question and answer session. I would now like to turn the floor over to Robert Piconi for closing comments.

Robert Piconi, Chairman and Chief Executive Officer, Energy Vault: Great, Alfredo. Thank you. Just in closing here, and hopefully as you’ve gone through the numbers and go through the charts, I again encourage everyone to download those. We are sharing more and more detail and some transparency on things that tie to the future profitability and growth of this business. I think a lot of the key metrics we share, the growth in the megawatts under management that have more than doubled since just going back, you know, since we last spoke, which wasn’t that long ago, 6, 7 weeks ago. Getting over that gigawatt, you know, that first gigawatt that’s within our control now to go execute, those are not small markers.

I think on top of that, you look at the backlog, which is a different cut, looking at what we’ve actually contracted. Just to highlight, you know, 80% now of that backlog that stands today at the $1.3 billion is contracted at much, much higher IPP type of gross margins.

Again, that’s something that should give investors a lot of comfort relative to the future profitability as we bring those online. Also just operationally, and this, I think is as investors look at teams and companies to invest in, the execution that we’ve had, if you look at just the last 6, 8 months, last year, one of the most challenging years starting off with the tariffs and uncertainty really through the first half of the year into the mid part of the year. Yet the team at Energy Vault executed and delivered. The only energy storage company to deliver on their, in their original guidance that we set for the year, and in a strong way in the quarter, delivering a positive adjusted EBITDA even in that last quarter as we delivered.

We’re expecting to do the same this year, and, you know, with strong execution, you know, expect to have some continual positive and upside surprises in what we’re doing just with the nature of our market penetration, and in particular, what’s happening here in the U.S. market. We have a lot underway. As I mentioned in answer to one of the questions here on other regions, other markets, we are staying very, very focused on these three core segments and just the very attractive core markets. That’s, you know, the Asia Pac, as far as Australia and Japan go. That’s in Europe we’re developing, I think some of the interesting own-and-operate opportunities there, as we’ve mentioned before.

In particular, right here at home in the U.S., and it’s required us to have a very nimble and diverse and dynamic supply chain, given the changes in the rules and FEOC, and a lot of the focus on domestic solutions. That is something our supply chain has been able to be very nimble and deliver, as we demonstrated in Q4. Really, as far as where we are at this point with what we have both under contract now and under development that’s within our control, as well as those opportunities, as referenced by one of the questions, our develop pipeline has more than doubled just from the last time we spoke, which was six weeks ago. These are really important markers to look at.

We’ve had a very good hit rate in terms of and conversion rate, I’ll call it, in terms of taking that developed pipeline and converting that, in particular, those megawatts into things that are within our control, meaning acquiring attractive points of interconnect. These are really the markers that I think investors should be looking at relative to the future with a very proven team that’s been able to execute and deliver here for customers at extremely high availability, which is at the end of the day now, how we’re really being judged by our customers, is being able to achieve that 99% plus availability that they, you know, not only require contractually, but really demand. It is a market requirement now as we look at power solutions.

Finally, just to, again, as I always do, none of this happens by itself or under standard processes and procedures. We have a very nimble and agile and hardworking and do-whatever-it-takes team at Energy Vault. A lot of hours worked to deliver what we deliver day in and day out. I wanna thank all the employees that make these results happen, that are passionate about delivering for customers, are passionate about maintaining our focus on sustainability. As, you know, we announced also this past quarter, two years in a row now being ranked the number one energy storage company, number one energy company in our industry from a sustainability score judged by S&P Global.

True to our mission, and the vision we wanna achieve as a company, I could not be prouder that the team here at Energy Vault and where we are today. Personally, I have never felt better about where this company is gonna go, what we’re gonna be able to achieve. We do not limit our thinking, in terms of where we go, how big the hill is to climb, and what it takes to get there. As all of you know listening in on this call, there’s no shortage of capital to put behind strong management teams in a very attractive space, with a proven track record of delivery. I think we hit on all those fronts. With that, operator, I’m completed the call here. I’ll turn it back to you.

Operator: Thank you. This concludes today’s teleconference. You may disconnect your lines at this time. Thank you for your participation.
