Rendimiento comercial y operativo
El ARDP y el proyecto de Dow
El ARDP respalda tres flujos de trabajo principales: el diseño de la planta de referencia Xe-100, el diseño y construcción de la instalación de combustible TX-1, y el despliegue de Dow en Seadrift, Texas. A fecha de 30 de junio, el DOE había reembolsado a X-Energy 547 millones de dólares en el marco del programa.
La contribución adicional propuesta por el DOE sigue sujeta al proceso contractual habitual y al mismo reparto de costes público-privado al 50%. El proyecto de Dow tiene como objetivo suministrar tanto electricidad como vapor industrial de alta temperatura.
HALEU y acuerdos de la cadena de suministro
La dirección identificó la disponibilidad de HALEU como una limitación comercial actual. X-Energy ha asegurado aproximadamente 7,6 toneladas métricas de material existente del DOE para las primeras cargas del núcleo de Dow y ha firmado acuerdos vinculantes de enriquecimiento con Centrus Energy Corp. y General Matter.
La configuración estándar de arranque del Xe-100 utiliza inicialmente combustible LEU. La dirección afirmó que esto se debe a los requisitos de arranque del reactor, neutrónica y reactividad, más que a la disponibilidad de HALEU. La planta TX-1 podrá fabricar tanto combustible LEU como HALEU, sujeto a diferentes consideraciones de criticidad.
X-Energy también acordó invertir hasta 8 millones de dólares en pagos basados en hitos para ampliar la capacidad de grafito de grado nuclear de SGL Carbon en Francia. La ejecución completa duplicaría la capacidad de grafito de grano medio de la instalación para 2030, respaldando lingotes para hasta ocho nuevos reactores Xe-100 al año.
Expansión del combustible TRISO-X
La Comisión Reguladora Nuclear (NRC) concedió a la operación TRISO-X una licencia comercial Parte 70 de 40 años en febrero de 2026. La dirección afirmó que se trata de la primera nueva instalación comercial de fabricación de combustible autorizada por la NRC en más de 50 años.
TX-1 está diseñada para proporcionar producción de combustible para aproximadamente 11 reactores Xe-100. La instalación TX-2 planificada tendría cuatro veces la capacidad de TX-1. En conjunto, se espera que el campus de Oak Ridge respalde una producción suficiente de combustible TRISO-X para aproximadamente 55 reactores Xe-100.
X-Energy adquirió 70 acres adyacentes en julio, ampliando el campus a aproximadamente 180 acres. La empresa también recibió una subvención de Tennessee de 11 millones de dólares para respaldar el TX-2 y el centro de investigación y desarrollo TXL.
Desarrollo de IA
X-Energy se unió al Proyecto Prometheus del DOE como miembro fundador y se comprometió a aportar 10 millones de dólares de capital privado, además de datos de diseño de reactores y fabricación de combustible. El programa de investigación de tres años explorará las aplicaciones de la IA en el diseño de reactores, operaciones semiautónomas y fabricación de combustible.
La empresa también está desplegando su plataforma de IA multiagente propietaria APEX en ingeniería, licencias y operaciones. La dirección afirmó que ya está generando ahorros de tiempo y costes.
Perspectivas de la dirección e hitos
- X-Energy prevé que la construcción vertical de TX-1 finalice en el tercer trimestre de 2026, seguida de la construcción interior, los servicios públicos y la instalación de equipos.
- La dirección prevé que el personal de la NRC resuelva todas las cuestiones de seguridad para el permiso de construcción de Dow a finales de agosto de 2026.
- La empresa sigue esperando la revisión final del permiso de construcción por parte de la NRC a finales de 2026, con la emisión prevista para el primer trimestre de 2027.
- Energy Northwest avanza hacia la presentación de la solicitud del permiso de construcción en la primera mitad de 2027. Se prevé que el proyecto sea el segundo despliegue de X-Energy y el primer proyecto dentro de su colaboración planificada de 5 gigavatios con Amazon.
- La dirección prevé que la capacidad de TX-2 sea necesaria a principios de la década de 2030. La instalación permanece en las fases de diseño, estimación de costes y planificación financiera inicial.
- La empresa afirmó que el cronograma de proyectos a largo plazo presentado anteriormente, que se extiende hasta principios de la década de 2030, no ha cambiado.
Riesgos y aspectos a vigilar
El suministro de HALEU sigue siendo una limitación comercial más amplia a pesar de los nuevos acuerdos. X-Energy no ha revelado las cantidades, los plazos, los precios ni los compromisos financieros a corto plazo de los contratos.
En la actualidad, la empresa utiliza su propio capital para asegurar el combustible y la capacidad de la cadena de suministro antes de que los clientes estén preparados para contratar directamente. La dirección tiene la intención de transferir estas obligaciones a los clientes en la etapa adecuada del proyecto, pero el calendario depende del desarrollo del mismo.
Los reembolsos del ARDP no equivalen exactamente a la mitad de los gastos operativos y de capital declarados en cada periodo debido a las diferencias en los plazos de pago y en la elegibilidad. El TX-2, el TXL y las instalaciones de combustible posteriores no están cubiertos por el reparto de costes del ARDP.
Los proyectos de X-Energy son a largo plazo y dependen de las licencias, la ejecución de la construcción, la financiación, la expansión de la cadena de suministro y el compromiso de la comunidad. La dirección no ofreció más detalles sobre el proyecto pendiente de 1 gigavatio con la empresa de servicios públicos hasta que las comunidades y socios pertinentes hayan sido informados.
Puntos destacados de las preguntas y respuestas de los analistas
- Financiación adicional del ARDP: La dirección no facilitó un coste total final para el programa de Dow. El CEO, Clay Sell, afirmó que la empresa confía en que el DOE y el Congreso seguirán respaldando el reparto de costes al 50% si se requiere financiación adicional.
- Alcance de los contratos de HALEU: Los acuerdos con Centrus y General Matter son vinculantes. La dirección señaló que cubren las necesidades de HALEU de los proyectos anunciados y posteriores, pero rehusó revelar los volúmenes, los precios o los plazos de entrega.
- Modelo de adquisición de combustible: Según el modelo a largo plazo previsto por X-Energy, los clientes comprarían y mantendrían el uranio, el enriquecimiento y el inventario de combustible relacionado. X-Energy está contratando con antelación para acelerar el desarrollo del suministro y asegurar la capacidad.
- Próximo proyecto de 1 gigavatio: La contraparte es una importante empresa de servicios públicos de propiedad de inversores, pero la dirección rehusó analizar la ubicación, la estructura comercial o la participación de un hyperscaler antes del anuncio formal.
- Financiación adicional: X-Energy está manteniendo conversaciones con varias entidades de financiación del gobierno de EE. UU. sobre una posible financiación de la deuda del proyecto, pero no se anunciaron compromisos.
- Cartera comercial: La dirección describió conversaciones activas con productores independientes de energía, empresas de servicios públicos de propiedad de inversores, clientes industriales, hyperscalers y empresas internacionales de servicios públicos, con algunas oportunidades en fases de viabilidad del emplazamiento y revisión.

We undertake no obligation to update any forward-looking statements, except as required by law. During this call, we also present non-GAAP financial measures. There are reconciliations of these measures included in our investor presentation posted on the Investor Relations portion of our website.
Joining me today are Clay Sell, our Chief Executive Officer; and Daniel Gross, our Chief Financial Officer. On today's call, Clay will open with a review of our recent highlights and operational updates, followed by what we believe are our compelling and differentiating business factors. Daniel will then review our financial performance for the second quarter in more detail before turning it back to Clay for closing remarks. We will then open the call up to Q&A.
With that, I'll now turn the call over to Clay.
J. Sell
Thank you, Patricia. Welcome all. Good morning. It's great to be with you today. What an extraordinary time to be in the business of bringing new power technologies to the market. Based on third-party estimates, global electricity demand is expected to increase more than 75% by 2050. About 1/3 of that growth is predicted to take place in our key markets, the U.S., the U.K. and Canada. And it's estimated that the market just for SMRs could be 158 gigawatts by 2050. That's a $2.3 trillion revenue potential.
At X-Energy, we have the opportunity to play a significant role in what will likely be the greatest build-out of power and electrical generation since the dawn of the electricity age. And we have a transformative next-generation technology and a great team of people that will allow us to reinvent and simplify the way nuclear power is built and expand the functions it can serve now and in the future. We're benefiting from a tremendous level of support and help along the way from our early partnership with the U.S. Department of Energy to our first announced customers in Dow, Amazon, Energy Northwest and the U.K. utility Centrica.
Now it will take us several years to fully unlock the scale of this business opportunity, but we want you to come to continue that journey with us today as we hit the news highlights and update you on our ARDP contract, supply chain agreements, developments at our TRISO-X fuel business, how we're using AI inside X-Energy, project milestones, licensing achievements, new customer agreements and our financial performance in the second quarter. We have a big agenda with a lot of news, so let's get to it.
I'll ask you to please turn to Slide 3. We're already there. I want to start with financing update on our partnership with Dow and the Department of Energy. Now you may recall that in 2021, X-Energy was competitively awarded and to date has been allocated approximately $1.1 billion under the Advanced Reactor Demonstration program, a 50-50 public-private partnership to deliver our first commercial power plant with Dow in Seadrift, Texas. This DOE grant award is our largest source of revenue at our current stage of development. Yesterday, the Department of Energy formally notified X-Energy that our ARDP cooperative agreement will receive up to an additional $1 billion. This funding will be subject to the same 50-50 cost share requirements as the original award and is expected to be obligated to the award as part of the normal contractual process with the department. So overall, that would increase DOE's cost share contribution to the ARDP up to $2.115 billion.
Our project with Dow is important, not only because it's our initial deployment, but because of the unmatched versatility for nuclear energy that it represents. When completed, our Xe-100s are expected to provide both electricity and high-temperature industrial steam for Dow's operations, demonstrating the range of applications our technology can address. And it is, of course, expected to be the first grid-scale advanced nuclear reactor deployed to serve an industrial site in North America.
Okay. Let's move to news updates on what we've done to strengthen our supply chain. And again, our supply chain goals are deliver for early projects, derisk and accelerate our ability to scale the business. The availability of HALEU fuel is a current commercial constraint. We've been executing on a strategy to retire that risk for our customers and our businesses for many years. The U.S. Department of Energy and the U.K. government as a result of our efforts and advocacy are financially supporting the construction of new HALEU production facilities. And those incentive contracts have now been awarded and facility expansions are underway. For our first core loads at Dow, we've secured existing material, about 7.6 metric tons from the Department of Energy. Over the last week, we have executed long-term agreements for HALEU enrichment services with both Centrus Energy Corp. and General Matter. Under the contracts, firm delivery commitments will grow through a phased approach to scale HALEU production in line with our expected commercial pipeline.
So including our HALEU allocation from the Department of Energy, we now have firm agreements to support the fuel needs for the initial and replacement core loads of our announced XC100 projects and beyond. Those agreements give us further certainty around the fuel supply required for our pipeline and are a meaningful step toward diversifying supply, increasing our competitive advantage and significantly reducing HALEU supply risk for our commercial pipeline.
Now let me move to another aspect of our supply chain, nuclear-grade graphite used inside our reactor core. Through an agreement we recently announced with SGL Carbon, we're working to expand SGL's production capacity for medium-grade graphite. We will invest up to $8 million in milestone-based payments to support new facilities and equipment upgrades at SGL's facility in Chedde, France. Full execution of this agreement would double SGL's manufacturing capacity for medium green graphite by 2030, enabling the facility to produce graphite billets for up to 8 new Xe-100 reactors per year. All these supply chain agreements are part of our strategy to allocate a portion of our IPO proceeds to secure capacity on behalf of our customers to incentivize early investments by our supply chain partners, to increase our competitive moat and reduce schedule risk for our early projects. As part of our plan, these contractual obligations are expected to be transferred ultimately to our customers. It's been a lot of good progress by our commercial and supply chain team this quarter.
So let me now turn to Slide 4 and then 5. I'd like to move to the latest developments of our TRISO-X fuel business. Our vertically integrated fuel fabrication business gives us greater control of an important piece of the reactor supply chain and will create recurring revenue opportunities for the company. In February of this year, we received our Part 70 commercial license from the Nuclear Regulatory Commission for an initial 40-year term. That was the first new commercial fuel fabrication facilities licensed by the NRC in over 50 years. Our first fabrication plant, which we call TX-1, and as you see in this picture, is being constructed with a 50-50 cost share with the U.S. Department of Energy and also received a competitively selected award for up to $148 million in federal tax credits, helping to overall reduce the project risk.
In addition, we appreciate the recent $11 million economic development grant from the State of Tennessee, which will be utilized to support the continued development of our potential second commercial fuel facility, which we call TX-2, and will also support the development of our dedicated research and development center, which we call TXL, all of these located on our campus in Oak Ridge. Our TX-2 facility is also covered under NRC's Part 70 license and is currently in the design phase. This facility is anticipated to produce 4x the capacity of TX-1. And once completed, this campus is expected to establish one of the world's largest commercial scale advanced nuclear fuel fabrication sites with the capacity to produce enough TRISO-X fuel to support approximately 55 of X-Energy's Xe-100 reactors. TX-1, TXL and the future TX-2 will form the core of our fuel fabrication and technology development campus in Tennessee.
As part of that growth plan, we acquired 70 acres of adjacent land in July. This purchase brings the site's total footprint to approximately 180 acres, allowing for continued expansion covered under our Part 70 license, and it provides additional space for utility corridors, equipment staging, fuel storage and long-term expansion. This week, we announced an extension to our cooperative research and development agreement with the Department of Energy's Oak Bridge National Lab. This agreement expands nearly a decade's worth of joint research, technology transfer and process development that has enabled TRISO-X to get ready to manufacture at commercial scale. We have achieved significant process improvements that we expect will continue to reduce the cost of TRISO fuel.
Let me give you an example. In our pilot plant, we have consistently achieved greater than 95% for first pass process yield on our kernel conversion process or TRISO fuel. This speaks to the mature process optimization in place at TRISO-X, and we anticipate receiving that level or better at commercial scale. What this means is that more uranium ends up in the pebble and not discarded as waste, which means lower cost fuel. TRISO-X's manufacturing capacity equips it to potentially earn the fuel business of customers beyond our own ex-energy fleet. We have the manufacturing expertise and the capabilities to produce various types of fuel to address the needs of a broader set of SMRs, microreactors and nuclear space applications.
Now if we'll return back to Slide 3, let me switch gears and talk about artificial intelligence. We often talk about AI and hyperscale data centers as a demand pull for nuclear. And certainly, we've experienced that in our own partnership with Amazon. But I want to briefly talk about how we are using AI tools to transform the way we do our business on the inside. At X-Energy, we embraced the use of AI to further accelerate nuclear development. We view every opportunity through the lens of reducing the time and expense required to design, license, manufacture and deploy the fuel and the reactors. We are excited to have recently joined the Department of Energy's Project Prometheus as a founding member, collaborating with organizations, including Idaho National Laboratory, NVIDIA and Amazon Web Services.
As part of our commitment, we're providing $10 million in private capital, along with the use of our reactor design and fuel fabrication data. Our data will serve as a technical basis for a 3-year research campaign, leveraging the DOE's test reactors and supercomputing capabilities to integrate frontier class AI models and uses from reactor design to semiautonomous operation workflows as well as fuel fabrication. Our partners -- our participation in this project builds upon the ongoing development of our internal proprietary tool called APEX. This is our multi-aggentic AI platform that we have currently deployed across our engineering, licensing and operations teams, where we are already realizing meaningful time and cost savings.
Now let's turn to Slide 6, and I'd like to briefly touch on the project -- on the progress of our near-term milestones. First, you will note that we added a line recognizing the agreements to significantly reduce our early HALEU supply risk, which occurred this month, and it's a notable achievement. Moving on down the line, the vertical construction for the shell of our TX-1 fuel facility is progressing on schedule and is approximately 80% complete today. We are on track to meet our third quarter near-term milestone for vertical construction completion and the commencement of the next scope of work for the interior build-out, which includes the construction of a graphite matrix powder building, utility installation and equipment installation in TX-1. On the NRC construction permit for Dow, we anticipate that the NRC staff will close all safety questions by the end of August. We continue to expect final review of our construction permit to be completed in late 2026 with the issuance by the first quarter of '27.
In Washington State, the Energy Northwest project is expected to be our second project online and the first of 5 gigawatts of new power projects with Amazon. This project will benefit from engineering, execution and licensing experience developed on the Dow project. Work with Energy Northwest is progressing as planned with Energy Northwest moving toward construction permit submission in the first half of 2027. Finally, regarding our plan to announce the next 1 gigawatt project in 2026, we are in the final throes of an agreement with a major investor-owned utility for our next 1 gigawatt project. It's coming to a close. This is extraordinarily exciting news. But given the larger interest of our partners and the local communities involved, a full announcement will be made in the near future. So stay tuned for more exciting details to come.
Let me turn to Slide 7. On last quarter's earnings conference call, we introduced our long-term milestone road map found here. We recognize that our projects are long dated and will take some years to come online. This road map provides you with the order of our project work streams extending into the early 2030s, so you can follow along with us on our progress as we make project development announcements. Since our last earnings conference call, there have been no changes to the anticipated time line presented on this slide.
I'd like to now turn it over to Daniel Gross, our CFO, to discuss our financial results for the quarter in more detail.
Daniel Gross
Thank you very much, Clay. Please turn to Slide 8. One note before I get to the numbers. This is our first quarter reporting as X-Energy, Inc. We closed the IPO the last week of April, so Q2 covers several weeks as a private company and then a little over 2 months as a public company.
In Q2 of 2026, total revenues and grant income were $54.6 million. That's $50.1 million of services revenue which is primarily the Xe-100 design work under the Advanced Reactor Demonstration Program, plus $4.5 million of grant income, which is primarily tied to the Dow demonstration reactor. Total revenues and grant income were up 154% compared to Q2 of last year. And the reason is straightforward. We're doing more engineering work and the cost share under the ARDP program reimburses us for roughly half of it. As of June 30, 2026, at the end of the quarter, the DOE has reimbursed $547 million to us under that program.
Total operating expenses in Q2 of 2026 were $164.6 million. This breaks down into direct costs of $86.7 million and SG&A of $77.7 million. But when looking at our SG&A for the quarter, it's important to recognize that $33.5 million of that expense was noncash equity-based compensation mostly from options that were granted to employees at the IPO. A little under half of that equity comp expense was a onetime charge recognized at the IPO when previously vested awards converted. And then the remainder of our equity comp awards will amortize over the remaining vesting periods.
So with revenue up 154%, total operating expenses were up 156% compared to Q2 of 2025. And there were 3 primary drivers: more ARDP work, more people and contractors doing that work and the equity-based compensation, which, as I mentioned, was a noncash expense. Below the operating line, interest income was $11 million on our investment portfolio, but this is offset by $6.3 million in expenses that are categorized as other income or expense net. But I want to unpack that so you can see where it's coming from. Most of that $6.3 million in expense was a noncash mark-to-market loss of $5.6 million on a warrant that was granted to an investor in 2022 and exercised in April of this year. And as the value of our equity went up, the fair value of the warrant also increased, so we had to book an expense. But no cash left the building and this won't repeat because the warrant has been exercised and the liability is gone. So netting it all out, total other income or expense was a positive $4.7 million.
Turning to cash flow. Operating activities used $97.3 million in the quarter, which is up from $20 million in Q2 of 2025. That reflects higher ARDP activity, corporate head count and contractors and some significant prepayments to vendors on long lead materials. Investing activities used $73.6 million in Q2. A lot of this was simply from rolling cash into debt instruments as other debt instruments matured. So we bought $126.6 million of short-term securities, and we had $92.8 million mature. We also spent $63.3 million on capital expenditures for construction projects including TX-1, for which ARDP reimbursed us $23.5 million in cash during the quarter. And that last figure raises a question that we get a lot. So let me answer it now. As Clay mentioned, ARDP is a 50-50 cost share.
So why is the reimbursement for CapEx and OpEx never exactly half of what we spent. Two reasons. So first, we spend the money and then we invoice and then we get paid. So the amount we report is cash spent on capital projects and the associated reimbursements were affected by the timing of our cash payments versus cash receives. Second, not everything we spend is ARDP eligible. The cost share covers the Xe-100 design work and TX-1. It doesn't cover TX-2 or TX-L or subsequent fuel facilities. And as Clay mentioned, we're continuing to progress the design work on TX-2. And so internally, we track eligible ARDP costs separately from ineligible costs, but in our financials, we report them together. So our financial statements are always going to include amounts of CapEx and OpEx that will never be reimbursed under ARDP.
If you'll turn to Slide 9, I'd like to walk you through our capital structure and balance sheet. We ended June with $1.9 billion in cash and investments, that's $1.1 billion of cash and cash equivalents, $490 million of short-term investments and $265 million of long-term investments. This liquidity is roughly double from where we were 3 months ago, thanks to the $1.1 billion of net IPO proceeds. We've invested this money conservatively. Feel free to call us boring, but our priorities are capital preservation, liquidity and credit quality. U.S. treasuries, high-grade corporates, commercial paper, money market and a few similar instruments, nothing exotic and everything matures before we expect to need it. At the end of Q2, we had 0 debt outstanding.
Please turn to Slide 10. Our SEC filings contain a number of non-GAAP measures, several of which are based on share count, and we thought that this additional color could help inform how you think about us. If you've ever pulled OpEx Energy's ticker on a smartphone app or use the data from many online financial sites, the market cap you're looking at probably doesn't -- or depending on which site may not reflect what we believe is the implied equity value of X-Energy as a whole. So let me explain why and what I'd suggest you use instead. When we went public in late April, we reorganized the company as an umbrella partnership C corporation or an Up-C, which you can see digrouned in the slide on the right-hand side. And here's the shorter. Because our Up-C structure has 2 classes of stock and different shareholders at the parent and the subsidiary level, your stock app may only be looking at our Class A common shares outstanding when it calculates the market cap. And these calculations are often excluding the Class B shares, which we think leads to a misleading outcome.
So holders of Class B shares hold an equal number of common units in our subsidiary, and those units can be redeemed for Class A shares. And since the Class B shareholders can redeem their common units for Class A shares, we think they should be viewed as having similar economic rights to Class A shareholders. Mind you, if they redeem their Class B shares will be canceled. And so given the possibility for this exchange, we think that for purposes of calculating our implied equity value, it's more important to add together 280 million Class A shares, plus 119 million Class B shares plus a combined total of 15 million shares of outstanding stock options, RSAs and RSUs and that would bring you to a total fully diluted share count of 414 million shares to use for calculating our implied equity value.
So that's the share count we would use if we were calculating implied equity value. And that's also the share count that we've used for earnings per share or in our current case loss per share comparisons. It's a non-GAAP measure, and you'll find the full reconciliation along with other non-GAAP measures, which we believe are useful in the earnings release and the 10-Q. Note that in those documents, we've also included an adjusted EBITDA calculation. And an adjusted earnings per share calculation currently loss per share, which consolidates together the A shares and the B shares.
With that, I will now turn it back over to Clay.
J. Sell
Thank you, Daniel. Let's go to Slide 11. Let me provide a few wrap-up comments before we go to questions. X-Energy intends to lead the way in building a technology and business model that will enable us to completely reinvent the way the world thinks about constructing and operating new nuclear at scale and provide the broadest array of functionality with the greatest geographic flexibility globally.
We believe we have the right technology backed by decades of development and operational experience. We believe we have the deepest experienced executive team. We believe we have the right business model. That's why X-Energy has earned the support and capital commitment of high-quality blue-chip customers and partners like Dow, Amazon and Centrica. We continue to enjoy strong support as evidenced today from our partner at the Department of Energy. We've been well received in the communities around our projects, where we are building or developing. We have secured significant supply chain commitments and are working to further derisk our projects and provide line of sight for the deployment of our reactors while continuing to build our commercial manufacturing for our TRISO-X fuel. X-Energy is uniquely positioned for the opportunity of this day, that's how we succeed in our multiple ways to win. X-Energy isn't built around a single project or a single source of revenue, it's built around a sustainable platform, intentionally designed to drive the growth of advanced nuclear for decades to come.
And with that, we will now take your questions.

[Operator Instructions] Our first question comes from Marc Bianchi with TD Cowen.
Preguntas y respuestas
Unknown Analyst
This is [indiscernible] on for Marc Bianchi. I had a question on the ARDP allocation, $2.1 billion allocated is a meaningful amount there. How much more is needed to reach the 50% share for the Dow project? Is that close to the mark? Or is the total share amount not finalized yet?
J. Sell
Yes. As you know, Evan, we've not fully -- we have not previously disclosed in our [ X-1 ] or other documents what the full cost of the program is going to be. You will recall that this program provides a 50-50 commitment for 3 big scopes of work. The design of our reference plant, Xe-100, the design construction and licensing of our first fuel plant, TX-1. And then in addition to that, the full project cost -- total project cost of the Dow deployment in Seadrift Texas. So that's the full scope of the 50-50 cost share. We have always enjoyed a strong commitment from the Department of Energy to see this through, strong commitment from Capitol Hill to continue to provide the appropriations to fund that.
I think this most recent $1 billion increase is evidence of that. And I'm confident to the extent more dollars can be required, they will be provided by our partners at the Department of Energy and the commerce because fundamentally, I mean you'll recall, the foundation of the ARDP program was created effectively in response to the technology peer competition that is currently underway with China. And the U.S. government made a decision years ago that we had to pick the best of our advanced technologies that could compete in the international market that we could first deploy here at home, and they chose X-Energy and they chose TerraPower to invest heavily.
And so I think the return on investment that we've been able to indicate through our partnerships with Amazon and Centrica and the significant backlog that we have identified makes the investments that the U.S. government are making to get us back into the nuclear game and extraordinary return. So we'll see where the number ends up, but I'm confident that the department and our advocates and Congress will stay committed to the 50-50 cost share.
Unknown Analyst
Got it. Okay. And then my follow-up is on the Janus program. You're a finalist there with Project Pele before with the XENITH reactor. And I think that program is moving along, I think, put possible announcements maybe later this year. Are you actively pursuing that opportunity? I know the DoD seems to be looking at multiple technologies for that. And it seems like you have an advantage with the high temperature gas reactor type they're already working on. So could we expect anything later this year?
J. Sell
I'll tell you, we have an extraordinary business opportunity in the deployment of Xe-100 in the manufacture of TRISO-X fuel. And that is what we are focused on. That is what our Board has directed us to do. That is where we think the great economic opportunity is. That's where we think the total addressable market is. And we are focused on that $2.3 trillion TAM that we can access with the Xe-100 and our TRISO-X fuel business. Specific announcements around the Janus program haven't been made, but I'll tell you, that's where our focus is on Xe-100.

Our next question comes from [ Joseph Osha ] with Guggenheim.
Unknown Analyst
Thanks for the really interesting update this morning. You guys have talked this morning about the fuel arrangements that you've got with Centrus and General Matter, which is great. I'm wondering if you can clarify what the initial downloads are going to look like, whether that implies you might start with HALEU now? Or is the plan still for the initial load to be LEU?
J. Sell
Thanks, Joe. So in our standard start-up configuration for an Xe-100 plant, you accurately recall that we first load LEU pebbles. And then the subsequent court is the second core is LEU pebble and the HALEU pebbles thereafter. And that's just a matter of how we manage the Nutronics and the reactivity and the start-up sequence. That's why we start with LEU. But -- let's see, what was the rest of your question?
Unknown Analyst
Okay. So no change there. And you clarified. I thought that the initial -- the fact that the initial load was LEU was perhaps more a reflection of the fuel supply situation and what you're saying is no, it's just -- it's part of the standard [indiscernible].
J. Sell
Absolutely not. The only reason we start with LEU on the Dow project is because that's the way we will start up every Xe-100 forever because that's what's required to manage the initial start-up, Nutronics and reactivity. But the halo that we need for the Dow project will be available to us when the plant towards the end of this decade when we need it to produce the first HALEU Corp for Dow. And then as I emphasized or I tried to emphasize in my prepared remarks, the -- we have secured through our initial contracts with Centrus and General Matter, sufficient HALEU to cover the second and subsequent core loads for our first announced projects and even beyond that. And we'll provide greater color on a go-forward basis as to that. But on those contracts, we have agreed contractually not to disclose specific timing, specific quantities and specific pricing. So I'm just trying to give you a shape of how we view the opportunity and what -- and the risk that we were seeking to reduce on our initial projects at X-Energy.
Unknown Analyst
That makes sense. And just a follow-up, just so that I understand, is there anything at the pebble manufacturing level, material handling, whatever, that varies between LEU and HALEU? Or is it pretty much exactly the same thing?
J. Sell
Well, we'll use the same facility, Joe, but there are different considerations based largely on criticality factors between LEU and HALEU, but we will be able to produce both of those cores in our TX-1 facility.

Our next question comes from Michael Sullivan with Wolfe.
Michael Sullivan
[Technical Difficulty].
J. Sell
Michael, I need you to speak up. I can barely hear you.
Michael Sullivan
Sorry about that. I just wanted to ask on the customer announcement that seems imminent here. You mentioned investor-owned utility. Do they have a hyperscaler lined up? Or is this preparing to just go into their rate base. How should we think about the structure of the order?
J. Sell
Michael, I would love to give you additional details, but you're going to have to wait. And we will provide clarity on the when, the where, the who and other details in the near future. real projects with real partners are real things, and they require a significant level of appropriate early community engagement. And so the communities, in my view, like the communities deserve to hear first, what's coming to their communities even before the investor community does. And so there is a process by which these agreements and plans get rolled out. And I think that's the right way to do business. And so all questions will be answered in time, but I just wanted to give an indication today that those announcements, the full details were imminent.
Marc Bianchi
Okay. Great. I can appreciate that. And just at the federal level, you had the ARDP update. I think the DOE recently announced some potential loans for utilities on the AP1000 side. Anything you see coming down the pike on the SMR side for your technology in terms of additional DOE funding outside of the ARDP that you already have?
J. Sell
We are -- we have ongoing dialogues with the full suite of financing entities inside of the U.S. government, everything from the Energy Diamonds Financing Group at the Department of Energy, the Strategic Capital Office at the Department of War, Accent Bank, DFC [indiscernible]. And we fully expect to be able to access those debt financing entities for our projects. So those are ongoing discussions. When we have something to announce, of course, of course, we will. But yes, ongoing discussions.
On the AP1000 commitment. Yes, I'll just tell you that I think there are places around the country where it may make sense to build AP1000s. But what I'm even more confident in is the opportunities and the customer interest in SMRs. I think just from my functionality from a safety case, from a geographic siding standpoint and just the monotone of the financial risk involved in bringing these projects to fruition. There are a lot of things that I think will move potential customers to our Xe-100 product. I mean, that's certainly what we're seeing. But just a few AP1000s get built, I think the country is better off for it.

Our next question comes from Julien Dumoulin-Smith with Jefferies.
Julien Dumoulin-Smith
Maybe just pick it up real quickly. Can you add a little bit more color on the fuel supply agreements here, nicely down on that front. You said it's sufficient to meet the announced project needs. Can you quantify whether that's in kilograms or gigawatt terms or what have you? Of what capacity and what it suffices to meet? And within that, are both of these agreements binding? And what are the financial commitments on your side at this point, especially in terms of liquidity in the next few years?
J. Sell
Julien, the agreements are minding these are real agreements. We have contractually agreed with our counterparties, not to disclose further details about timing quantity and price. And so I'm not going to be in position today to be fully responsive. But I will tell you, it has given us great confidence that we have contractually retired the HALEU risk as it relates to the first [indiscernible] loads on our announced projects and beyond. That's what I'm prepared to say today and more details will be provided at the appropriate time.
From a contractual obligation standpoint, Julien, let me just kind of go back and tell you big picture. In our normal application of our business model in a fully up and running market, fuel would be procured by our customers, the uranium, the enrichment services, deconversion, et cetera. That would be an obligation of our customers. They would buy it, they would hold the inventory. So that begs the question. Why is X-Energy doing that now? And the answer is because we are at the start up of the creation of a full diverse functioning and well-supplied halo market. And we want to be part of creating that. We want to secure capacity that will serve as a competitive moat for our customers, and we fully intend to transfer those obligations to our customers at the appropriate time in the state of the project.
So the benefit of us allocating some of our capital to this effort now and securing these contracts is we secure capacity. We help accelerate the investment that we require from Centrus, General Matter and others to build out these HALEU cascades, and we can do that in a manner, quite frankly, before our customers are prepared to enter into those contracts. But with the full intention that we will assign those contracts to them and they will take them over on a go-forward basis and have this supply. Does that make sense?
Julien Dumoulin-Smith
Yes. No, thank you for disclosing as much as you can. I appreciate that. Let me -- look, interesting follow-up related to this is you guys announced this incremental 70 acres, right, for fuel fab, adjacent. Can you talk about what you're contemplating for this TX-2 here just to kind of keep going on the fuel line of questioning? And the timing on that, just given the activity there? I mean, obviously, we talked about scaling this up.
J. Sell
Yes. So just to sense, TX-1 basically provides enough throughput capacity for 11 Xe-100s. And we have an active development far more than that. And so we estimate at some point in the early 2030s, we will need to bring TX-2 online. What we are doing right now is completing the design completing the cost estimates and beginning the early phases of our financing business plan to bring TX-2 to fruition. But that's what we're doing now. We have no further announcements as it relates to the initiation of construction for the final securing of financing for TX-2.
Julien Dumoulin-Smith
Awesome. And just to nitpick a little bit on the last question there. As it pertains to the eminent announcement that is with a utility or just what kind of counterparty, if I can. I know you said it's not going to go. I appreciate it. And that's the last one.
J. Sell
I'll just repeat what I said in my prepared remarks, [indiscernible]. Julien, who knows them better than you.

[Operator Instructions] Our next question comes from David Arcaro with Morgan Stanley.
David Arcaro
Let's see, great progress on the supply chain efforts this quarter on graphite and HALEU. I was wondering, is there an area that you would be focused on next in terms of derisking further long lead materials or equipment in your supply chain?
J. Sell
Well, you've seen us -- David, thanks for the question. We've been pretty active across a number of fronts. And I think what we've communicated in the past is we're focused on the large steel components in our -- inside our nuclear steam supply system. Those are primarily produced by Doosan. And you've seen us enter into similar long-term supply agreements with Doosan. We have entered into -- we announced our agreement on steam generator tubes. We have some other agreements in the works. We've talked about HALEU, we've talked about graphite. What else?
I think there are other types of graphite that we use inside the reactor that we're also focused on. But we have a fairly disciplined approach that is run by our outstanding supply chain team about where we need to invest early and quite frankly, where we can secure advantage with some early capacity securing agreements. And as we enter into those, we'll continue to make those announcements to the public.
David Arcaro
Yes. Got it. Understood. And then I understand we'll have to wait a little bit longer for that 1 gigawatt -- the details around the gigawatt announcement here. But could you give just any color around conversations with other customers, other projects and just advancing other conversations in the -- or other opportunities in the pipeline? How are they going? And what's the level of interest and activity?
J. Sell
Yes. We have a robust level of discussions across the full range of target customers, IPPs, investor-owned utilities, industrial customers, hyperscalers, foreign utilities, et cetera. For some of those, we are in the further phases of discussion and site feasibility and review. And so we -- I think we have a very, very robust set of conversations. It just takes -- it takes time and it takes a lot of work to get a real project to the start line. And I remain confident that we have a very robust set of opportunities and multiple shots on goal for the remainder of the year.
Operator
Thank you. I'm showing no further questions at this time. I would now like to turn it back to Clay Sell, Chief Executive Officer, for closing remarks.
J. Sell
Well, thank you, everyone. I appreciate you joining us today. I'm a little bit disappointed that the great and eloquent Daniel Gross did not receive any follow-up questions so we'll ship for that in the next quarter. We do look forward to sharing additional updates as we continue to execute against our near-term milestones and show you how we are positioning this company, X-Energy, to be the leader in the nuclear industry. Really appreciate your time, and we look forward to seeing you on the road and our next conference call. Thank you.
