ROCKVILLE, Md., Aug. 13, 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 second quarter 2026 financial results and operational highlights.
“Our progress in the second quarter reflects our continued focus on execution across every part of our business,” said J. Clay Sell, CEO of X-energy. “We are investing in capabilities that better position the company for commercial execution and scale. Our HALEU enrichment service agreements meaningfully de-risk a substantial portion of the deployment of our reactors, and the agreement with SGL secures our access to critical graphite components, enabling our strategy to build reactors at scale. Through our ongoing partnerships with ORNL and the State of Tennessee, as well as our recent partnership with Project Prometheus, Idaho National Lab, NVIDIA, and AWS, we are working to further lead nuclear innovation through the best tools and resources available."
“Overall, we believe this momentum only reinforces our ability to deliver for our customers and continues to build a moat between us and our competitors. We remain focused on building the technology delivery platform to help meet the demands for clean, reliable nuclear energy,” concluded Sell.
Operational Highlights
- Secures Strategic HALEU Enrichment Services: Executed commercial order for HALEU enrichment services, entering into long-term supply agreements with Centrus Energy Corp. and General Matter to support the deployment of its commercial pipeline of Xe-100 SMRs.
- Expands Joint Supply Chain for Key Reactor Material: Announced agreement to double SGL Carbon’s European production capacity for medium-grain isotropic graphite (“NBG-18”), a specialized material central to X-energy’s Xe-100 high-temperature gas-cooled reactor (“HTGR”). Under the agreement, among other terms, X-energy will invest up to $8 million in milestone-based payments to support new molding facilities and furnace upgrades at SGL’s facility in Chedde, France. Full execution would double European manufacturing capacity for NBG-18 by 2030, enabling the facility to produce graphite billets for up to 8 new Xe-100 reactors per year.
- Received Continuation Application Approval from the DOE: X-energy has received formal approval of its ARDP continuation application for a budget period extension through March 2027. The ARDP provides X-energy with a 50/50 cost share to continue work toward design, licensing, commercialization, and construction of its first-of-a-kind commercial advanced nuclear plant in collaboration with Dow in Seadrift, Texas, and TX-1, its first commercial TRISO-X fuel fabrication facility.
- TX-1 Vertical Construction Nears Completion: Vertical construction for the shell of the Company's TX-1 fuel facility in Oak Ridge, Tennessee is progressing on schedule. The Company is on track to meet its near-term milestones for vertical construction completion and the commencement of support building and interior build-out, scheduled to begin in the third quarter of 2026 as planned.
- TRISO-X Fuel and TX-1/TX-2 Continues to Accelerate: TRISO-X, a leading manufacturer of advanced nuclear fuels and wholly-owned subsidiary of X-energy, was awarded an $11 million economic development grant from the State of Tennessee. The funding will support the continued development of the Company’s fuel fabrication campus in Oak Ridge, Tennessee, including an expected second commercial fuel facility, TX-2, and a dedicated research and development center. The award demonstrates Tennessee's continued support for TRISO-X’s efforts to build one of the world's largest TRISO fuel facility campuses.
In July, TRISO-X extended its relationship with the DOE's Oak Ridge National Laboratory through entry into a cooperative research and development agreement. This agreement expands upon a strategic collaboration that has played a central role in advancing commercial-scale TRISO fuel development and manufacturing since 2016. The 30-month agreement builds on nearly a decade of joint research, technology transfer, and process development that has enabled TRISO-X to transition to advance fuel manufacturing processes readiness to manufacture at commercial scale.
Also in July, the Company acquired approximately 70 acres of land adjacent to its commercial nuclear fuel campus in Oak Ridge, Tennessee. This expansion supports the continued development of the Company’s fuel fabrication campus, increasing TRISO-X's footprint to approximately 180 acres and is covered under the NRC's Part 70 fuel fabrication license.
- Founding Member of DOE's AI Initiative: The Company recently joined the DOE's Project Prometheus as a founding member, collaborating with organizations including Idaho National Laboratory, Nvidia, and Amazon Web Services to accelerate advanced nuclear deployment through the use of artificial intelligence. The Company committed $10 million in private capital, along with the use of its Xe-100 HTGR design and fuel fabrication data. This data will serve as a technical platform for a three-year research campaign, leveraging the DOE’s test reactors and supercomputing capabilities to integrate frontier-class AI models into reactor design, licensing, manufacturing, construction, and semi-autonomous operation workflows, as well as fuel.
- Strengthened Balance Sheet with Initial Public Offering (“IPO”) Net Proceeds: 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.

Total revenues and grant income in the three months ended June 30, 2026 were $54.6 million, including $50.1 million of services revenue and $4.5 million of grant income. Total revenues and grant income in the six months ended June 30, 2026 were $98.0 million, including $90.0 million of services revenue and $8.0 million of grant income. Total revenues and grant income increased 154% and 132% for the three and six months ended June 30, 2026, respectively, compared to the comparable prior-year period. This was primarily due to increases of $31.9 million and $56.0 million in revenue and grant income from the ARDP Agreement with the DOE for the three and six months ended June 30, 2026, respectively. This was driven by an increase in project execution activities under the ARDP Agreement as the Company continued to advance the development and finalization of the Xe-100 reactor design. The increase reflected higher spending on materials, subcontractor services, and payroll to support the expanded scope of work.
Total operating expenses in the three months ended June 30, 2026 were $164.6 million, including $86.7 million of Direct costs. Total operating expenses in the six months ended June 30, 2026 were $274.2 million, including $152.0 million of Direct costs. Total operating expenses increased 156% and 146% for the three and six months ended June 30, 2026, respectively, compared to the comparable prior-year periods. This was primarily due to increases of $50.5 million and $87.2 million in Direct costs and increases of $50.4 million and $76.5 million in Selling, general, and administrative expenses for the three and six months ended June 30, 2026, respectively, compared to the comparable prior-year periods.
The increase in Direct costs was primarily driven by expanded activity under the ARDP Agreement. Subcontracting costs increased by $23.5 million and $32.0 million for the three and six months ended June 30, 2026, respectively. Direct materials costs increased $3.5 million and $17.7 million for the three and six months ended June 30, 2026, respectively. Additionally, direct labor costs increased by $21.7 million and $34.2 million for the three and six months ended June 30, 2026, respectively, including $16.5 million and $27.6 million from higher employee headcount to support the expanded activity under the ARDP Agreement, and $5.2 million and $6.6 million from increased non-cash equity-based and unit-based compensation expense for the three and six months ended June 30, 2026 due to equity grants to certain holders of Profits Interest Units (“PIUs”) in April.
The increase in Selling, general, and administrative expenses was driven by an increase in non-cash equity-based and unit-based compensation expense of $28.1 million and $30.9 million for the three and six months ended June 30, 2026, respectively, due to the equity grant to certain PIU holders discussed above. Compensation costs increased $10.5 million and $20.3 million for the three and six months ended June 30, 2026, respectively, primarily due to higher employee headcount. Additionally, infrastructure and professional service costs increased by $6.9 million and $14.1 million for the three and six months ended June 30, 2026, respectively.
Net cash used in operating activities in the six months ended June 30, 2026 was $164.6 million of net cash compared to $61.8 million for the six months ended June 30, 2025. The increase in cash used in operating activities is primarily driven by an increase in activity on the ARDP Agreement, including deposits to vendors for long-lead materials, as well as increases in corporate headcount and corporate contractors during the six months ended June 30, 2026 compared to the six months ended June 30, 2025.
Net cash used in investing activities in the six months ended June 30, 2026 was $239.6 million of net cash compared to $18.7 million for the six months ended June 30, 2025. The increase in net cash used in investing activities was primarily attributable to an increase in purchases of fixed-income securities of $316.5 million, and a $70.7 million increase in capital expenditures related to the construction of facilities during the six months ended June 30, 2026. These increases in cash outflows were partially offset by an increase in proceeds from investment maturities of $130.9 million and a $35.3 million increase in reimbursements received during the period for capital expenditures qualifying under government grant programs.
Net cash provided by financing activities in the six months ended June 30, 2026 was $1.1 billion of net cash compared to $50.4 million for the six months ended June 30, 2025. The net cash provided by financing activities during the six months ended June 30, 2026 was primarily due to $1.1 billion of net proceeds from X-energy’s initial public offering. The net cash provided by financing activities during the six months ended June 30, 2025 was primarily due to the January 2025 issuance of Series C-1 preferred units of $53.4 million, offset by $2.5 million of cash paid for associated issuance costs.

| X-ENERGY, INC. RECONCILIATION OF GAAP TO NON-GAAP FINANCIAL MEASURES (in thousands, except share and per share data) | ||||||||||||||||
| Adjusted Net Loss, Fully Diluted Share Count, and Adjusted Net Loss per Share, Diluted Non-GAAP fully diluted share count is defined as the weighted average of Class A common stock outstanding for the period reported if (i) all of the holders of X-Energy Reactor Company, LLC (“XERC”) Common Units redeemed their XERC Common Units for shares of X-energy’s Class A common stock on a 1:1 basis (and effected the cancellation of their Class B common stock of which they hold an equal number to the number of XERC Common Units they hold), (ii) all of X-energy’s outstanding options (whether or not vested and whether or not in-the-money) that remain outstanding were exercised for Class A common stock and (iii) all of X-energy’s outstanding RSAs and RSUs vested. Adjusted net loss adjusts GAAP net loss attributable to X-Energy, Inc. by (i) including net loss attributable to XERC prior to the IPO, (ii) including net loss attributable to non-controlling interests subsequent to the IPO, (iii) excluding equity-based and unit-based compensation and (iv) excluding mark-to-market losses on warrant liabilities and C-2 Notes from Net Loss. Adjusted net loss per share, diluted is calculated by dividing Adjusted net loss by the fully diluted share count. Management uses these non-GAAP financial measures to evaluate potential shareholder dilution, facilitate period-over-period comparability, and support internal planning and capital allocation. Management believes they provide investors useful supplemental information. Non-GAAP fully diluted share count helps investors assess the potential impact on the Company's capital structure of outstanding XERC Common Units redeemable for Class A common stock (with an equal number of Class B common stock cancelled) and equity awards, while Adjusted net loss and Adjusted net loss per share, diluted aid period-to-period comparisons by excluding certain non-cash items that may obscure underlying operating trends. Including net loss attributable to non-controlling interests enables investors to evaluate the operating results of the Company’s consolidated business without regard to its ownership structure. | ||||||||||||||||

| (1) | Holders of shares of Class B common stock hold an equal number of XERC Common Units (as defined in the condensed consolidated financial statements in the Company's Quarterly Report on Form 10-Q for the period ended June 30, 2026). XERC Common Units can be redeemed for shares of Class A common stock or, at the Company's election in certain circumstances, cash. At the time of redemption of XERC Common Units for shares of Class A common stock, an equivalent number of shares of Class B common stock are cancelled. | ||||||||
| (2) | The Company currently has a warrant outstanding that is exercisable for 14.1 million shares contingent upon future events or performance conditions. This warrant is not currently included in the fully diluted share count as it was not deemed probable of vesting as of June 30, 2026. | ||||||||
| (3) | Net loss per share, diluted is calculated by dividing the Net loss attributable to X-Energy, Inc. by the Weighted average shares of Class A common stock outstanding, basic and diluted. | ||||||||

Adjusted EBITDA
Earnings Before Interest, Income Taxes, Depreciation and Amortization (“EBITDA”) adjusts Net loss attributable to X-Energy, Inc. by (i) including net loss attributable to XERC prior to the IPO, (ii) including net loss attributable to non-controlling interests subsequent to the IPO, and then adjusting for (iii) interest expense, (iv) interest income and (v) depreciation and amortization expense. EBITDA is used by management to evaluate the Company’s operating performance by excluding the effects of financing decisions, income taxes, and non-cash depreciation and amortization, which can vary significantly between companies due to differences in capital structure, tax positions and asset bases. EBITDA is useful to investors because it allows investors insight into the Company’s core operating performance and facilitates comparisons across reporting periods.
Adjusted EBITDA is EBITDA excluding (i) equity-based and unit-based compensation and (ii) mark-to-market loss on warrant liabilities and C-2 Notes. Adjusted EBITDA is used by management to assess the Company’s operating performance. Management believes these adjustments exclude variables unrelated to the Company’s core operations and allow for meaningful comparisons between the Company’s operating results from period to period.
