Key Terms

generic design assessment, high temperature gas-cooled reactor, u.s. nuclear regulatory commission, finding of no significant impact, +3 more
7 terms
generic design assessment regulatory
"Submitted application to enter the United Kingdom's Generic Design Assessment"
A generic design assessment is a regulatory review that checks whether a proposed generic medicine matches the original branded product in key ways — like ingredients, how it is made, and how it behaves in the body — so it can be approved as interchangeable. For investors, the outcome signals whether a lower‑cost competitor can enter the market, which can quickly change sales, pricing power, and projected profits for both the original maker and prospective generic manufacturers.
high temperature gas-cooled reactor technical
"for its Xe-100 High Temperature Gas-cooled Reactor (“HTGR”)"
A high temperature gas-cooled reactor is a type of nuclear power plant that uses an inert gas (usually helium) to carry very hot heat away from fuel encased in ceramic-coated particles or graphite blocks instead of using water. For investors this matters because the higher operating temperatures can improve efficiency and enable industrial uses like hydrogen or process heat, offering potential low‑carbon revenue streams but with large upfront costs, long development times and regulatory risk.
u.s. nuclear regulatory commission regulatory
"Received U.S. Nuclear Regulatory Commission (“NRC”) Environmental Assessment"
A federal agency that licenses, inspects and enforces safety rules for civilian nuclear power plants and other uses of radioactive materials in the United States. Think of it as the official safety inspector and rulemaker for the nuclear industry—its approvals, inspections, fines and rule changes can speed up or delay projects, change operating costs, and alter legal and financial risk, so its actions directly affect companies’ prospects and investor value.
finding of no significant impact regulatory
"with a Finding of No Significant Impact (“FONSI”)"
A finding of no significant impact is a formal government determination that a proposed project or action is unlikely to cause meaningful environmental harm, so a full, lengthy environmental study is unnecessary. For investors, it reduces regulatory risk and shortens approval timelines—like getting a quick green light instead of being sent back for a full inspection—affecting the likelihood and timing of permits, costs, and expected cash flows.
high-assay low-enriched uranium technical
"manufacture fuel using high-assay low-enriched uranium (“HALEU”) at its first"
High-assay low-enriched uranium (HALEU) is uranium processed to contain a higher percentage of the atom that sustains a nuclear chain reaction (U‑235) than standard reactor fuel but well below weapons-grade, typically about 5–20% U‑235. It matters to investors because HALEU is the preferred fuel for many advanced reactors and some medical isotope production, so its availability, production capacity, regulation and geopolitical risks can materially affect project timelines, supplier contracts and valuation of companies in the nuclear supply chain.
small modular reactors technical
"Exploring deployment of Xe-100 small modular reactors (“SMRs”) with Louisville"
Small modular reactors are compact nuclear power plants built from factory-made modules that are assembled onsite, like snapping together building blocks to add or replace capacity. They matter to investors because they aim to lower upfront costs and shorten construction time versus traditional reactors—potentially providing steady long-term power sales and service revenue—while still carrying regulatory, construction and waste-management risks that can affect returns.
pjm interconnection regional transmission organization technical
"across the PJM Interconnection Regional Transmission Organization (“PJM”)"
PJM Interconnection is a nonprofit regional transmission organization that runs the high-voltage electric grid and wholesale power markets across a large multi-state area. It acts like an air-traffic controller and marketplace for electricity, coordinating which generators run, managing reliability, and setting wholesale prices. Investors care because PJM’s rules and market outcomes influence utility and generator revenues, power price volatility, project economics, and regulatory risk for energy-related assets.

ROCKVILLE, Md., June 04, 2026 (GLOBE NEWSWIRE) -- X-Energy, Inc. (NASDAQ: XE) (“X-energy” or the “Company”), a leading designer of advanced nuclear reactor technology and manufacturer of nuclear fuels, today announced first quarter 2026 financial results for X-Energy Reactor Company, LLC, the predecessor company to X-Energy, Inc., and operational highlights.

“Our first earnings announcement as a public company marks an important moment for X-energy and reflects the progress we are making to commercialize advanced nuclear technology at scale,” said J. Clay Sell, CEO of X-energy. “During the first quarter of 2026, we remained focused on advancing the development of the Xe-100 and TRISO-X fuel, while continuing to strengthen the regulatory and commercial foundation needed to support long-term deployment.”

“This quarter’s regulatory achievements reflect the strength of X-energy’s long-term approach to licensing and regulatory engagement,” Sell continued. “As the industry works to bring advanced nuclear technologies to market, we believe our ability to achieve first-of-their-kind regulatory approvals helps to establish a stronger foundation for the future commercialization and deployment of advanced nuclear at scale. At the same time, we continued strengthening the commercial foundation of the business through strategic supply chain partnerships, preliminary agreements with domestic utilities, and continued construction of our TX-1 fuel facility in Tennessee.”

Daniel Gross, CFO of X-energy added, “Our recent IPO enhanced X-energy’s liquidity profile, providing approximately $1.1 billion dollars in net proceeds of additional capital as we work on bringing advanced nuclear technologies to market. Supported by our industry-leading customer base, our IPO further bolsters our leadership in SMR deployment and commercialization.”

Operational Highlights

  • Project Milestones: In May, the NRC completed its Environmental Assessment as part of Dow’s Construction Permit Application for the proposed advanced nuclear project in Seadrift, Texas. The NRC’s review was completed ahead of schedule following a comprehensive independent analysis, concluding with a FONSI. The project is being partially funded under the U.S. Department of Energy's Advanced Reactor Demonstration Program (“ARDP”) and would provide both electricity and high-temperature industrial steam to Dow’s UCC Seadrift Operations. Development efforts are also currently underway for the first Amazon-backed project with Energy Northwest.
  • TRISO-X Fuel and TX-1/TX-2: Received a Special Nuclear Material License under Part 70 from the NRC, enabling TRISO-X to commercially manufacture fuel using high-assay low-enriched uranium (“HALEU”) at its first two commercial facilities (“TX-1” and “TX-2”) under an initial 40-year license. Vertical construction for TX-1 in Oak Ridge, Tennessee is underway and the facility remains on schedule for completion by the first half of 2028. In addition, irradiation testing for the TRISO-X pebble fuel is in progress at Idaho National Laboratory in collaboration with the NRC.
  • Strategic Partners: Entered into a 10-year graphite supply agreement for reactor components of the Company’s Xe-100 SMR, which supports its first commercial deployment for Dow’s Seadrift project under ARDP and is expected to provide a foundation of supply for future projects. Additionally, the Company signed a Memorandum of Understanding with IHI Corporation, a leading nuclear-grade supplier for critical components used in X-energy’s HTGR, to explore opportunities for commercial-grade manufacturing of nuclear-grade components.
  • Business Development: Announced a collaboration with LG&E and KU, subsidiaries of PPL Corporation, to explore deploying Xe-100 SMRs in Kentucky to meet growing energy demand across the Commonwealth, and large load customers, including data centers. Early project feasibility activities have begun and could potentially be supported by the state’s Nuclear Reactor Site Readiness Pilot Program, which includes a $75 million grant initiative to support nuclear site feasibility studies, applications for early site and construction permitting, and licensing. Three projects are expected to be selected to receive up to $25 million each. The Company also recently signed a Letter of Intent with Talen Energy to assess deploying three or more four-unit Xe-100 plants in Pennsylvania and across the PJM market to add clean baseload capacity to help support reliability and meet growing energy demand from onshoring of manufacturing, data centers, and electrification. Under the agreement, X-energy and Talen plan to conduct early-stage project development activities, including feasibility studies, site evaluations, and a project execution framework.
  • Regulatory: Submitted an application to enter the U.K.'s GDA process for its Xe-100 HTGR to advance the Company's commercial partnership with Centrica. Subject to acceptance, this is the established regulatory pathway for licensing new nuclear technologies, evaluating safety, security, safeguards, and environmental impact independent of site-specific applications in the U.K.

    Coordination with the NRC for review of a construction permit application for a proposed advanced nuclear project at The Dow Chemical Company’s UCC Seadrift, Texas site is ongoing. Dow and X-energy’s Construction Permit Application for the proposed advanced nuclear project in Seadrift, Texas, achieved a historic milestone as the first commercial reactor to receive environmental clearance through an Environmental Assessment instead of a years-long Environmental Impact Statement. Following a comprehensive independent analysis, the NRC completed its assessment ahead of schedule and issued a FONSI.
  • Corporate: On April 24, 2026, the Company began trading on Nasdaq under the ticker “XE” and on April 27, 2026, the Company closed its IPO, raising approximately $1.1 billion in net proceeds. The use of proceeds is intended for working capital and other general corporate purposes, which may include research and development and sales and marketing activities, general and administrative matters, and capital expenditures, including spending necessary for supply chain and procurement activities, in addition to potentially funding future growth projects.

Net cash provided by (used in) financing activities  (1.1)  50.9   (102)%
             

Total Revenues and Grant Income in the three months ended March 31, 2026 were $43.4 million, including $39.9 million of Services Revenue and $3.5 million of Grant Income. Total Revenues and Grant Income increased 109% compared to the three months ended March 31, 2025 primarily due to a $21.6 million increase in revenue and grant income from the ARDP Agreement with the Department of Energy (“DOE”). This was driven by an increase in activities and nature of services performed.

Total Operating Expenses in the three months ended March 31, 2026 were $109.5 million, including $65.4 million of Direct Costs. Total Operating Expenses increased 133% compared to the three months ended March 31, 2025 primarily due to an increase of $36.6 million in Direct Costs and an increase of $26.1 million in Selling, General, and Administrative expenses. The increase in Direct Costs was driven by increases of $12.0 million and $11.7 million in subcontracting costs and direct materials, respectively, which were driven by an increase in activity related to the ARDP Agreement, and an increase of $11.4 million in direct labor costs which was driven by an increase in employee headcount to support activity under the ARDP Agreement. The increase in Selling, General, and Administrative expenses was primarily due to an $8.7 million increase in payroll-related costs due primarily to increases in employee headcount and a $3.1 million increase in unit-based compensation expense due to new grants made during the year ended December 31, 2025. Selling, General and Administrative expenses further increased by $6.1 million due to contractor costs related to corporate projects and a $5.2 million increase in professional fees and enterprise software costs for general corporate use.

Net Cash Used in Operating Activities in the three months ended March 31, 2026 was $67.3 million, a 61% increase compared to the three months ended March 31, 2025, primarily due to an increase in activity on the ARDP Agreement, an increase in corporate headcount, and an increase in enterprise software costs and corporate contractors.

Net Cash Used in Investing Activities in the three months ended March 31, 2026 was $166.0 million, reflecting $43.0 million of capital expenditures and $28.8 million of reimbursements for capital expenditures received from the DOE under the ARDP. The increase in Net Cash Used in Investing Activities compared to the three months ended March 31, 2025 was primarily due to purchases of investments of $189.9 million, and a $31.7 million increase in capital expenditures related to the construction of facilities, including TX-1. These increases in cash outflows were partially offset by a $38.1 million increase in proceeds from investment maturities and a $19.3 million increase in reimbursements received during the period for capital expenditures qualifying under government grant programs compared to the three months ended March 31, 2025.
