Thank you for standing by. This is the conference operator. Welcome to the NexGen Energy Second Quarter of 2025 Results Conference Call. As a reminder, all participants are in listen-only mode and the conference is being recorded. I would now like to turn the conference over to Mr. Leigh Curyer, Chief Executive Officer and Director with NexGen Energy Limited. Please go ahead, sir.

Thank you, Joseph. Good morning, and thank you for joining NexGen's Q2 2025 Financial Results and Investor Conference Call. My name is Leigh Curyer, and I am Chief Executive Officer. Today, I'm joined by Travis McPherson, Chief Commercial Officer; and Benjamin Salter, Chief Financial Officer. On today's call, I'll discuss our exciting company advancements, including Rook 1 Project Readiness, Patterson Corridor East results, which strongly validate another significant mineral body unfolding 3.5 kilometers to the east alongside Arrow. Further, the PCE results clearly suggest a very significant uranium mineralizing event has occurred in the Southwest region of the Athabasca Basin, Saskatchewan, on an unprecedented scale. We are really only at the beginning of defining its true extent. Furthermore, the exciting developments in the uranium market over the quarter, including yesterday's announcement of NexGen doubling the volume in our offtake book, incorporating our key focus of market-related pricing mechanisms. This ensures NexGen Energy delivers industry-leading leverage to future prices while providing utilities with confidence regarding volumes from Rook 1's technically, environmentally, and socially responsible operation. All in all, updating the critical role NexGen is set to play in delivering the world this vital clean energy fuel supply. At the conclusion of this presentation, we'll move to the Q&A portion of the call, where you will have the opportunity to ask Travis, Ben, and myself your questions. Throughout the course of today's call, we will be making forward-looking statements. Please visit our website for all the relevant disclaimers. A few years ago, the idea of nuclear energy powering big tech, winning back global financing support, and forming the cornerstone of national energy policy might have seemed optimistic. Today, it's happening. In just the past several weeks, we've witnessed a series of transformational developments that are reshaping global perceptions of nuclear energy. Developments that signal a clear structural shift is occurring today and forecasted to extend well beyond 2050. In Q2, corporate buyers, particularly hyperscalers and AI leaders, moved aggressively to secure long-duration baseload power for their required energy needs. These technology companies have committed over USD 100 billion in AI data center construction, including Amazon's $20 billion spend on data centers in Pennsylvania; Meta signed a 20-year power purchase agreement with Constellation Energy to secure 1.1 gigawatts of nuclear-generated electricity, which could power the equivalent of approximately 1 million homes. In addition, Constellation confirmed its nearing long-term nuclear fuel supplier deals with other hyperscalers. Google has committed to funding the development of three advanced nuclear projects and TerraPower, and Orwell raised another combined USD 1.1 billion to develop small modular reactors. The race for energy, particularly clean baseload nuclear, is on, and the growth in demand has never been more robust. These are just a few examples of the decade-long commitments to nuclear energy from the most capitalized and data-dependent companies on the planet. According to the International Energy Agency, data center demand for electricity is set to increase by 170% in China, 130% in the U.S., 80% in Japan, and 70% in Europe over the next 5 years. This equates to an insatiable desire for uranium to fuel large portions of this demand through nuclear energy. The reality is that current mine supply will not keep up with the existing demand and certainly not meet the exponential demand growth unless there are higher prices. Governments, including here in Canada under Prime Minister Mark Carney, are also moving with urgency, fast-tracking regulatory frameworks, investing in small modular reactor development, and emphasizing domestic supply chains as a matter of national security. In May, President Trump signed a series of executive orders to accelerate U.S. nuclear power development, aiming to quadruple nuclear capacity from 100 to 400 gigawatts by 2050. Immediate actions include funding 5 gigawatts of upgrades for existing plants, starting construction on 10 new large-scale reactors by 2030, restarting closed or unfinished reactors, fast-tracking permitting, and constructing at least three new reactors by 2026. The U.S. Department of Energy will also direct funding to new projects, invest in fuel cycle infrastructure, all to prioritize U.S. energy security and supply chain independence. This is the most comprehensive nuclear policy ever seen, and it has profound positive implications for NexGen, which is Western-based, low-cost, environmentally responsible, and poised to start construction upon the conclusion of the CNSC commission hearing process commencing one of two sessions only 99 days from now. In Canada, the passage of Bill C5 enables the Government of Canada to fast track major projects aligned with national, economic, environmental, and indigenous priorities, an approach that reinforces the direction NexGen has taken since its inception. While Rook 1 is already well advanced under the current regulatory framework, the passage of Bill C5 presents a clear opportunity for the federal government under Prime Minister Carney and Minister Hodgson's leadership to demonstrate this new legislation in action—something that is much needed in Canada for the country to realize its potential as a natural resources world leader. As a project that unambiguously meets the criteria of national interest, delivering economic benefit, environmental excellence, and deep indigenous partnership through legally binding, industry-leading benefit agreements, Rook 1 is capable of providing $37 billion in economic benefit to Canada during the first 10 years of forecasted production. We will support 1,400 direct jobs and be initially licensed beyond 2050. NexGen's Rook 1 project exemplifies every aspect of the criteria that the Carney government has defined for projects to be prioritized through Bill C5, and we look forward to the conclusion of the CNSC process to deliver the many stakeholder-led benefits our project exhibits. None of these developments are isolated; they are strategic signals from the private sector, financial institutions, and government policymakers alike that nuclear energy has moved from the sidelines to the center of the global energy preference. Nuclear is not just part of the solution; it is foundational. At the core of this shift is a single truth: the world needs more electricity, and it needs to be clean, reliable, and affordable. It's not just about the power; it's about energy security, economic prosperity, and national competitiveness, all underpinned by the requirement to supply the key ingredient, uranium. All these developments and a lack of supply lay the groundwork for structurally higher uranium prices in the foreseeable future. The reality is that the industry at large, to some extent, still believes that this can all be solved with higher prices over a reasonable timeframe. However, to meet the exceptional growth in demand we're seeing, you need many new Arrow-sized projects to be found, delineated, engineered, permitted, funded, and built. Arrow is widely considered the most technically sound and environmentally benign deposit globally, and we are entering the 12th year since its discovery. Our decision to relaunch exploration in 2023 at Rook 1 has paid immediate dividends, with our PCE discovery, which we will evaluate in significance as drilling and development advance. I'll speak more in a moment about PCE. While the global policy environment accelerates, the uranium market is also gaining ground. In Q2, uranium spot prices rose over 20%, closing at USD 78.50 per pound, largely driven by the re-entry of the Sprott Uranium Trust following a $200 million raise. It was a powerful reminder that the uranium market is very undersupplied and that when demand volume returns to the market, prices respond rapidly. Furthermore, yesterday, NexGen announced a new offtake agreement with a major U.S.-based utility, which doubles our contract book in volume. Importantly, and distinguishingly from past practices, our pricing on the 10 million pound contract book is all U.S. utilities and is market-related at the time of delivery, providing unprecedented leverage to investors in this rising uranium pricing environment. At the same time, given our superior technical setting and environmental design, it provides confident diversification of a new Western world supply. Our contract book represents approximately 3% of our total defined resources and underscores NexGen's patient and strategic approach to building its sales book. We're in advanced discussions with utilities across North America, Europe, the Middle East, Asia, and negotiations are increasingly urgent, informed, and fast-moving. With the commission's hearing set for September 25 and February 2026, NexGen is preparing to transition from advanced development to construction and subsequent operations. Our current cash balance stands at CAD 375 million, with funding to complete the 2025 site programs and initiate development for the first 12 months of post-approval construction. We maintain full strategic optionality with a strong cash position and active engagement with global debt providers, sovereign funds, and utilities, amongst others, resulting in financing interest well in excess of the full funding requirements of the build. As we always have, we will optimize the vast number of financing alternatives available for maintaining our production flexibility and ultimately maximizing the value of each pound of uranium we produce and sell. At PCE during the quarter, NexGen announced our best discovery phase assay to date. We drilled hole RK-25-232, returning an incredible 15 meters at 15.9% U3O8, including an exceptional peak of 0.5 meters at 68.8%. This is among the best exploration intercepts in the world, with Arrow hosting the majority of the other top 10. Since discovery, 45 holes at PCE have intersected mineralization. Of these, 12 have produced the ultra-high-grade massive replacement mineralization of over 61,000 counts per second. We've been bold with our spacing, in some cases, over 200 meters apart, and are still intersecting mineralization consistently, demonstrating the continuity of mineralization and the overall strength of the system. Drilling to date at PCE confirmed the start similarities to the Mighty Arrow deposit just 3.5 kilometers away, suggesting the early signs of another Tier 1 assay. It really does speak to the vast discovery potential of more deposits on the Rook 1 property in the future. We also recently announced the consolidation of our entire land package, including PCE with the purchase of Rio Tinto's 10% production carried interest held on 39 of our claims. NexGen has secured a right of first refusal mechanism over this package after a third party made a bona fide offer to acquire it from Rio. NexGen now holds 100% ownership of all its claims in the district. This speaks to the acceptance by NexGen and others of the tremendous value in the Southwestern Athabasca Basin portfolio, which dominates the known and prospective trends in the district—a district often referred to as the future of uranium mining. In response, we have received regulatory approval to expand our exploration infrastructure, including a temporary airstrip, road for dual-way traffic, and expanded accommodations to support a growing team on site. This program is currently underway and scheduled to be completed in Q1 2026. Our elite standards on responsible development continue to guide every part of the business. In May, we released our fifth annual sustainability report aligned with Global Reporting Initiative and Task Force for Climate-related Financial Disclosure Standards, highlighting major advancements across environmental, social, and governance metrics. Through our growing education and workforce development programs, over 500 participants have engaged in NexGen-led training initiatives these past two years across a wide range of skilled trades. These programs, developed in partnership with regional institutions and indigenous communities, are designed to build capacity and create meaningful career paths aligned with the project's long-term needs. Indigenous leaders have publicly recognized NexGen's unique and leading collaborative approach with all four of the indigenous nations in the local project area, citing NexGen as a benchmark for meaningful indigenous engagement and shared prosperity. Keeping an eye on talent, I advise you to keep an eye out for a video on our website about Chantelle Herman, who is one of a group of talented local students who have become members of the NexGen team, pursuing highly technical careers at NexGen while still living in their community. Chantelle is one of these leaders in the community, and Travis and I met back in 2015 at the National School Volleyball tournament. She went on through our summer student program, followed by a scholarship, and is now a second-year geology student while working as a field geology technician at Rook 1. This is one of many great outcomes from the Rook 1 project and is the foundation for delivering even greater generational advancement of the project as it goes into construction and operation. NexGen is well advanced on procurement with long lead and critical path items already ordered and, in several cases, staged and secured in our warehouse. This progress reflects NexGen's fully integrated execution strategy and proactive supply chain planning, ensuring we are ready to begin major construction immediately upon final regulatory approval. With the team, materials, and partnerships in place, Rook 1 is execution-ready. As we enter the next phase, our focus is clear: conclude approvals, finalize funding, and begin building the most important new uranium project in a generation in a manner fully consistent with how NexGen has delivered the best results across every aspect of the organization. At NexGen, we're advancing with clarity and conviction. We're executing with deep respect for the environment, communities, Saskatchewan, Canada, the world, and our shareholders. We are energized by the opportunity to lead the future of nuclear. We appreciate your continued support and look forward to delivering further progress in the second half of the year. Thank you, and we will now open the call to your questions.

And we will take our first question here coming from Katie Lachapelle with Canaccord.

Congrats on the new offtake. Similar to your previous agreements, you noted that it was a market-related contract. Two questions. Can you confirm if there's floors and ceilings in that new contract? And then as a follow-up, it appears that you're signing better terms relative to what some of your peer companies are announcing. Is that fair to say? And if so, what do you think is giving you that edge?

I can confirm that our contracts as a blend are very substantially market-related prices at the time of delivery. There's not one contract that fits all. Contracts are very specific to the technical and sovereign profile of either the producer or the emerging producer, and also the particular circumstances of the utility. I would make a general comment that U.S. utilities, particularly the larger ones, do prefer surety around future pricing. And so what you'll see with those contracts is an embedded floor and ceiling. Where that is the case with NexGen, I want to say that we have four contracts in place, which cover all aspects: floor and ceiling, full spot, and then also no floor and an extremely high ceiling. They are, based on our knowledge of the market, very strong relatively. I think that speaks to a number of things: the overall assessment by utilities regarding the state of the current mine supply worldwide and significant sovereign and technical risk impacting some of the current producing centers. Thus, NexGen represents, along with other advanced developers in Canada, an alternative or diversified supply of this key important fuel. Ultimately, I think that gets reflected in the pricing from what has occurred in the past to what is actually about to unfold in the future.

Awesome. Maybe just one quick follow-up. In the past, you've indicated, I think it was upwards of USD 1.6 billion in lending interest from banks and other credit providers. Is that number around the same, or has that changed? And now that you've got a couple of these offtake contracts in hand, do you feel like you're getting closer to finalizing an agreement on the debt side?

Yes. And I'll hand over to Travis to answer.

Yes. Thanks, Katie. As Leigh indicated, yes, it is growing, I would say. There's more parties getting involved seemingly every week, frankly. I think that's on the back of all those banks signing that agreement to support the funding of this growth initiative by all these international governments. The funding of nuclear projects is well in excess of that, and offtakes, I would say, do help the lending process, but it also opens up potentially new avenues of lending with government as an example. To be clear, the offtake contracts are being done on an isolated basis based on our acceptance of those terms; it’s not like we're conceding on anything that we want long-term. So yes, it's very positive, and we are really interested in funding the full project along the timelines that we've indicated in the past, which is end of the year into Q1 next year ahead of the approval process. Also, debt is one of the alternatives at hand. As Leigh mentioned earlier in the call, we do have quite a few options available to fund the full project.

Our next question will come from Andrew Wong with RBC Capital Markets.

So just maybe back on financing a little bit. With regard to that, as you're having more of these conversations with various partners and there's more and more interest, what's your sense on the most likely path here? Is having a strategic partner, or sorry, a strategic partner the most preferred path and then maybe that's supplemented by debt or equity? Can you maybe just provide a sense on that?

Yes. Thanks. Maybe I'll start. I would say we don't have a preferred path at this stage; we're keeping an open mind to all avenues at hand. They all come with their own considerations. I would say all of them are advanced, but obviously at various stages of development. All of them are attractive in isolation or together. So I would say we're maintaining a very open mind regarding how this ultimately gets funded. Although, obviously, we are focused on our ability to be flexible concerning production volumes and maintaining our leverage to future upside in prices.

Yes, exactly. Look, our principle is to finance it in a manner that optimizes the production and the return on every pound produced. We're working both streams—both equity and project equity, debt, and also the potential of a prepayment on the future supply of a volume of pounds. Each one of them comes with their costs and benefits, but the overall principle that we will incorporate when we conclude the package is optimizing exposure to future uranium prices. While we can't be specific on the debt-to-equity percentage or whether it's project equity or not, that will be the guiding principle. We will most likely conclude that in the first half of 2026, subject to respect for the conclusion of the CNSC hearing process.

Okay, great. Then just maybe on the project itself in terms of construction, given that the approval might be coming sometime in the first half of next year. Can you just talk about how the project team is shaping up right now? Can you highlight any construction expertise you've hired or if there are any notable additions recently?

Yes, it's a good question, Andrew; one that we don't make a lot of noise about. But behind the scenes, there's a well-planned human resource execution underway. We've been adding to the team consistently since 2017 in line with the stage of development. Look, there's no doubt we've appointed some people that are ready to go and start constructing this mine. And obviously, when we've seen a quality hire, we've brought them on board. They're busy; they're not sitting around doing nothing, that's for sure. On balance, we're probably over-employed, but it is going to pay extreme dividends once we have that approval and are into the construction phase. The benefit of a long permitting process is that it provides plenty of opportunity to plan, review, plan again, and review again. I can tell you that our construction plan is down to finite detail. We know exactly what we're building. It's technically a very simple mine in a mining sense, and we've attracted the best in the business onto the team. We have a combination of both direct employees and consultants, but our overall philosophy at NexGen is that we don't delegate any decision-making. We have a person on the team that takes responsibility for their respective field. That responsibility ultimately rests with Travis and myself and the Board. So we are very much an owner-constructor and operator model.

And our next question will come from Ralph Profiti with Stifel.

Leigh and Travis, I just want to delve a little bit into these two offtake contracts being held to a 5-year term. Was there appetite on the part of the counterparties to move those contracts out to a further tenure? And what's holding back movement on the floors and the ceilings? Is this becoming the industry standard or are there other factors at play, specifically with regards to the tenure?

The contracts are very different depending on the actual asset and the utility. There's not one contract that suits all. This is also reflective of the utilities' specific requirements. Utilities have a range of contracts with different suppliers, and some are short-term while some are long-term. I would classify ours as medium-term in terms of length. We are just at the beginning—we're at 3% of our total defined resources at Arrow. We all know that the Arrow deposit is much larger and given its inferred resource, which will convert to indicated with subsequently closer space drilling. I would say our philosophy is—at the moment, we're negotiating a variety of contracts ranging from 3 years, 5 years, and 10 years. This is really dependent on the specific circumstances of the utility. Those characteristics differ from one region to the next worldwide; U.S. utilities have a different preference compared to Asian utilities, who have a different preference versus European utilities. I want to emphasize that there's not one contract in this market that fits all. It is very specific to the utility and very specific to the producer.

That's very helpful. I appreciate that. And Leigh, you mentioned Bill C5 a couple of times in your pre-prepared comments. Now that we're 6 months from that second CNSC hearing, has there been any scope changes regarding plant, equipment, or components in the design that are directly being driven by Bill C5? I'm asking this to think about scope changes in the early preconstruction phase of the project.

Yes, interesting question, but the answer is no. There have been absolutely no scope changes whatsoever, full stop, and we wouldn't be contemplating scope changes as a result of Bill C5. Our approach, since even prior to discovery, has been to deliver an environmentally elite approach along with a socially elite approach. We have done that. In every respect, we have exceeded the requirements of legislation from a technical and environmental perspective and from a social perspective, it's well documented that we've been incredibly proactive in engaging and consulting with indigenous communities and implemented programs where there is strong collaboration between NexGen and those communities. This extends beyond those that are defined as impacted. I think Bill C5 reflects Prime Minister Mark Carney's government recognizing that there are elements of duplication to permit a resource project—not just specific to uranium, but major energy and national infrastructure projects. I applaud them for recognizing this and introducing legislation that aims to make the whole process more efficient while maintaining incredibly high environmental and social standards that Canada leads the world in. That’s why we are in Canada. This aligns with our values as an organization, and we are very proud to deliver this project to Canada in line with the high environmental and social standards that Canadians expect.

And our next question will come from George Ross with Argonaut.

It's Sam. Just regarding the production carried interest, when is the market going to be informed a little bit more on the cost, etc., attached to that?

Well, it's confidential as per the agreement of the clause that triggered it. Yes, we are unable to disclose what it means or what the cost was specifically in relation to that acquisition. I will say we are very pleased to have acquired it. We had approached Rio Tinto on it, and then yes, bona fide bid was received by an external party, and we triggered our right of first refusal. Whoever that party was, thank you for expediting the process.

Fair enough. Okay. And just regarding the Patterson trend, any plans to test along strike at this point, Leigh? Or is it very much going to be focused on defining the higher grades at PCE?

Yes. Our initial focus is to define and extend what we have at PCE. Look, we've also seen the results at Patterson, which is basically an extension of the Patterson Corridor East trend of our property; they've hit mineralization as well. What that tells us is that the whole conductor is very highly prospective for additional mineralization. As I speak, we've explored less than 1% of that actual Patterson Corridor East conductor trend. Similarly, with Arrow, we've explored less than 10% of that particular conductor corridor. Everyone knows you have RRR along the Patterson Corridor conductor of our project. So the area is extremely well mineralized, and we are on the cusp of truly defining its extent. We have 8 conductor corridors running through the Rook 1 project alone. There's no doubt there's been a significant mineralizing event in the region, and yes, we've put in an exploration camp to facilitate extensive exploration of that region, hosting 320,000 hectares. It's incredibly exciting; it really is a geological phenomenon. Yes, there's a lot of drilling to be done before we can truly say this is the extent of it.

And our next question will come from a private investor.

You mentioned Rook 1 is execution-ready, and you've been held back, in my view, for some time now awaiting the federal approval process. You mentioned C5, and I have a couple of questions along that theme. Has C5 triggered some conversations with the government on advancing mine approval? And secondly, might there be some movement on the government schedule that you mentioned earlier in the call? I'm asking because of the principles of fast-tracking associated with Bill C5.

Thank you for the question, and it's a very topical one. I would say that the introduction of Bill C5 from Prime Minister Carney is absolute recognition that there are some efficiencies to be gained at the federal level, particularly after provincial approval and the indigenous community approval in the region of a specific project. He’s been very clear about that. As a consequence, he’s going to resource a new project’s office to help fast-track the federal process. I absolutely applaud Prime Minister Carney and his ministers for that endeavor. The NexGen project is so advanced in the process that these initiatives are going to really benefit other projects that come after NexGen. We are resource industry advocates, and we’re excited about that because NexGen isn’t going to fill the gap on its own. The world needs, with respect to uranium, two to three Arrows—and they need them now. I think that's excellent news for every other advanced developer out there looking to get into construction.

Our next question will come from Brian MacArthur with Raymond James.

If I can just go back to the contracts, there's been a lot of talk about floors and ceilings. But can you confirm or deny whether there are any volume options in those contracts? It sounds like there isn’t the way you're talking about how much is committed, but I'm just trying to figure out how that part of the equation is working in all these contracts.

Yes, Brian, there's no volume discretion in the contracts by the utility or us as the supplier. I'd make a general statement that the form, structure, and pricing of the contracts are changing from what has been done in the past. The environment is changing. The contracts we are doing are different and have different elements compared to what has been done before. You’re going to see that naturally evolve as the scarcity and the risk, be it sovereign or technical around supply, increases. My overall comment is the environment is changing, and what we are conveying to the market is what we are experiencing; it's different for all companies, specific to the technical and sovereign profile of your supply, and also very specific to the particular utilities' preferences that differ between the U.S., Asia, and Europe.

Great. That's very clear. Second thing, can I just confirm there's been a couple of comments about the financing and timing, whether it's year-end or H1 next year around the CNSC approval? Could you have financing in place before the CNSC approval? And would that be subject to CNSC approval? Or are they sort of dependent on each other? Any comments on that would be helpful.

Yes, they're obviously related. If we were approved today, we would have concluded the financing. We've been well-prepared for this for many years. But we can't really trigger the financing until we have approval to that extent. So as the final approval timetable unfolds, so will the financing. Terms or optionality may be better in the future given the way this environment is changing. We are just keeping our exposure to that in place, but I assure you we will conclude financing in short order post-approval.

There are just different time horizons talked about, so I was just trying to clarify that. I appreciate it.

This concludes the question-and-answer session. I'd like to turn the conference back over to Leigh Curyer for any closing remarks.

Yes. Thank you all for listening and joining the Q2 call. Thank you for your questions; we certainly appreciate them and everyone's interest in this incredible project. Q3 is going to be an incredible quarter ahead of us with everything that we're working on and the conclusion through the end of the year—not just what's happening at NexGen, but driven by what is occurring in a very rapidly changing market environment. We appreciate your interest in our project, and we look forward to continuing to deliver on the milestones we have articulated.

This brings to close today's conference call. You may disconnect your lines. Thank you for participating, and have a pleasant day.
