X-energy (Nasdaq: XE) subsidiary TRISO-X began the next phase of construction at its TX-1 advanced nuclear fuel fabrication facility in Oak Ridge, Tennessee. The work includes interior build-out, process and fuel-fabrication equipment installation, and new auxiliary structures, with Clark Construction continuing as general contractor.
According to X-energy, the 214,000 sq. ft. plant is expected to produce 700,000 TRISO-X pebbles per year (5 MTU), enough to fuel up to 11 Xe-100 reactors. TRISO-X holds a 40-year NRC Special Nuclear Material License, the first Category 2 HALEU fuel facility license. Recent steps include extending collaboration with Oak Ridge National Laboratory, acquiring 70 additional acres at Horizon Center, and securing a Tennessee economic development grant to support expansion.
X-energy (Nasdaq: XE) reported second quarter 2026 total revenues and grant income of $54.6 million, up 154% from $21.5 million in Q2 2025, driven mainly by higher activity under its 50/50 cost-share ARDP agreement with the U.S. Department of Energy for the Xe-100 reactor project.
Total operating expenses rose 156% to $164.6 million as direct costs and selling, general and administrative expenses increased with expanded project execution, higher headcount and equity-based compensation. The April 2026 IPO generated about $1.1 billion of net proceeds, lifting June 30, 2026 liquidity to $1.9 billion (no debt). The company secured long-term HALEU enrichment agreements, a capacity-expansion deal with SGL Carbon, an $11 million Tennessee grant and added ~70 acres to its Oak Ridge fuel campus. The project pipeline totals 144 reactors in the U.S. and U.K., or roughly 11.5 GWe, assuming full exercise of contingent rights.
X-energy (Nasdaq: XE) subsidiary TRISO-X has extended its cooperative research and development partnership with the U.S. Department of Energy’s Oak Ridge National Laboratory through a new 30‑month agreement. The collaboration, active since 2016, focuses on advancing commercial-scale TRISO nuclear fuel manufacturing via joint research, technology transfer, and process development.
The agreement allows TRISO-X to continue operating its pilot fuel fabrication facility at Oak Ridge, optimizing fuel quality, yield, and characterization methods. It complements construction of the TX-1 commercial TRISO fuel plant and a planned R&D center within TRISO-X’s growing Oak Ridge fuel campus.
X-energy (Nasdaq: XE) and Centrus Energy (NYSE: LEU) signed a definitive, long-term enrichment services agreement covering low-enriched uranium (LEU) and high-assay low-enriched uranium (HALEU) for X-energy’s Xe-100 advanced small modular reactor program. At full execution, X-energy said the deal meaningfully de-risks its Xe-100 project pipeline and secures HALEU to support a portion of the initial fuel needs for its 11.5 GW commercial pipeline.
HALEU from Centrus’s American Centrifuge Plant in Piketon, Ohio will be supplied to X-energy’s subsidiary TRISO-X for TRISO-X coated particle fuel fabrication in Oak Ridge, Tennessee, under a phased approach that scales production with X-energy’s commercial pipeline. TRISO-X holds a 40-year NRC special nuclear material license, and X-energy is advancing more than 11 GW of Xe-100 capacity in the U.S. and U.K. with projects involving Dow, Amazon and Centrica.
TRISO-X (Nasdaq: XE), a wholly owned subsidiary of X-energy, acquired approximately 70 acres of land adjacent to its commercial nuclear fuel campus in Oak Ridge, Tennessee, expanding its Horizon Center Industrial Park footprint from about 125 to over 180 acres.
The added acreage is intended to support utility corridors, equipment staging, fuel storage, and long-term expansion, including a planned second commercial fuel facility (TX-2) and an R&D center (TX-L) alongside the first facility (TX-1). The move follows a July 2026 Nuclear Energy Fund award and builds on TRISO-X’s decade of operations and its NRC commercial license for HALEU fuel fabrication.
X-energy (Nasdaq: XE) and SGL Carbon announced a binding agreement to double SGL’s production capacity for medium-grain isotropic graphite NBG-18, a nuclear-grade material central to X-energy’s Xe-100 high-temperature gas-cooled reactor. X-energy will invest up to $8 million in milestone-based payments to upgrade SGL’s Chedde, France site, enabling graphite billet production for up to 8 Xe-100 reactors per year. SGL will also expand U.S. capacity to machine billets into graphite blocks, aiming to improve continuity for this safety-critical, long-lead material. Full execution is expected to double European NBG-18 manufacturing capacity by 2030, building on a 10-year Supplier Framework Agreement signed in January 2026 that included an initial three-year award valued at over $100 million for X-energy’s first commercial projects, including its proposed four-unit Xe-100 plant with Dow (NYSE: DOW).
X-energy (NASDAQ: XE) announced it will report its second quarter 2026 financial results and operational highlights on Thursday, August 13, 2026, with a press release issued before the market opens.
The company will host a webcast and conference call at 8:00 a.m. ET, accessible via the Events & Presentations section of its Investor Relations website, where presentation materials will also be available. A replay of the webcast will be hosted on the site for at least one year. X-energy designs advanced small modular nuclear reactors and TRISO-X fuel for clean, safe and reliable energy applications across grid, industrial and AI markets. The company also uses its website, Investor Relations page and social media accounts on X and LinkedIn to share material information and meet Regulation FD obligations.
X-energy (Nasdaq: XE) has been named a founding Tier 1 partner in Project Prometheus, a three-year AI-for-nuclear research initiative led by Idaho National Laboratory, NVIDIA and AWS. The project was awarded $60 million under the U.S. Department of Energy’s Genesis Mission.
X-energy will contribute $10 million in private capital and provide proprietary data and designs for its Xe-100 small modular reactor and TRISO-X fuel. Its HTGR technology will serve as a core technical platform, with the company expecting to leverage AI advancements across its 11 GW commercial nuclear pipeline in the U.S. and U.K.
TRISO-X, a subsidiary of X-energy (NASDAQ: XE), received an $11 million economic development grant from the State of Tennessee to support expansion of its advanced nuclear fuel fabrication campus in Oak Ridge. The funding, from Tennessee’s Nuclear Energy Supply Chain Investment Fund, will help advance a potential second commercial fuel facility (TX-2) and a dedicated R&D center (TX-L) adjacent to the first facility (TX-1), now under construction with the U.S. Department of Energy.
According to the company, TX-1, TX-2 and TX-L are designed to create one of the world’s largest commercial-scale nuclear fuel campuses, with capacity to fuel about 55 Xe-100 reactors, representing roughly 4.5 GW of power for 3.3 million U.S. homes. TRISO-X holds a 40-year NRC Special Nuclear Material License covering TX-1 and TX-2 and expects more than 1,000 permanent jobs from TX-2.
X-energy (Nasdaq: XE) reported 1Q 2026 total revenues and grant income of $43.4 million, up 109% year-over-year, driven mainly by ARDP work with the DOE. Operating expenses rose to $109.5 million. Liquidity totaled $944 million with no debt, excluding about $1.1 billion of IPO net proceeds closed in April 2026.
Key milestones included an NRC FONSI for Dow’s Seadrift project, a 40-year Part 70 fuel fabrication license, a 10-year graphite supply agreement, U.K. GDA application submission, and a project pipeline of 144 Xe-100 reactors totaling about 11.5 GWe.
