A copy of the press release, as well as a copy of the accompanying earnings presentation, are furnished as Exhibit 99.1 and Exhibit 99.2 hereto, respectively, and incorporated herein by reference.

The information in this Item 2.02, including Exhibit 99.1 and Exhibit 99.2, is furnished and shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise subject to liabilities under that section, and shall not be deemed to be incorporated by reference into the filings of the Company under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporation language in such filings, except as shall be expressly set forth by specific reference in such filing.

## Item 7.01 Regulation FD Disclosure.

## Expected Early Lock-Up Release Date
In connection with the public offering of the Class A common stock, par value $0.0001 per share (the "Common Stock"), of the Company, all of the Company's officers, directors, and substantially all of the Company's holders of outstanding Common Stock were parties to lock-up agreements with the underwriters that restrict their ability to sell or transfer their shares, or otherwise engage in certain transactions related to their shares, for a period of 180 days after April 23, 2026, the date of the final prospectus relating to the public offering (the "Prospectus"), subject to certain exceptions. Such period is referred to as the "Restricted Period."

Pursuant to the lock-up agreements with J.P. Morgan Securities LLC, as representative of the several underwriters (the "Representative"), the "Restricted Period will end ten trading days prior to the commencement of a blackout period if (i) at least 120 days have elapsed since the date of the Prospectus and (ii) the Restricted Period is scheduled to end during or within five trading days prior to a blackout period..." The Restricted Period is scheduled to end on October 20, 2026, which falls within the Company's quarterly blackout period. Therefore, under the lock-up agreements, the Restricted Period will end on September 1, 2026, ten trading days prior to the commencement of such blackout period, and the shares subject to the lock-up agreements will become eligible for sale in the public market (subject to any additional applicable trading limitations).

The information in this Item 7.01 is furnished and shall not be deemed "filed" for purposes of Section 18 of the Exchange Act, or otherwise subject to liabilities under that section, and shall not be deemed to be incorporated by reference into the filings of the Company under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporation language in such filings, except as shall be expressly set forth by specific reference in such filing.

**X-energy Reports First Quarter 2026 Results** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Revenues and grant income of $43 million, compared to revenues and grant income of $21 million in 1Q 2025

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Raised approximately $1.1 billion in net proceeds through initial public offering ("IPO") and began trading on the Nasdaq Global Select Market ("Nasdaq") under the ticker "XE"

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Submitted application to enter the United Kingdom's Generic Design Assessment ("GDA") process for its Xe-100 High Temperature Gas-cooled Reactor ("HTGR")

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Received U.S. Nuclear Regulatory Commission ("NRC") Environmental Assessment for Dow's advanced nuclear project in Seadrift, Texas in May, with a Finding of No Significant Impact ("FONSI")

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Received Part 70 fuel fabrication license from the NRC, enabling commercial manufacturing for TRISO-X fuel

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Signed key supply agreement with SGL Carbon for graphite supply and MOU with IHI Corporation for critical HTGR components

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Exploring deployment of Xe-100 small modular reactors ("SMRs") with Louisville Gas and Electric Company ("LG&E") and Kentucky Utilities Company ("KU"), subsidiaries of PPL Corporation, in Kentucky, and with Talen Energy in Pennsylvania and across the PJM Interconnection Regional Transmission Organization ("PJM")

**ROCKVILLE, Md., June 4, 2026 –** 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**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**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.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**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.

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.

We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended. Such statements can be identified by the fact they do not relate strictly to historical or current facts. Words such as "assume," "believe," "continue," "could," "estimate," "expect," "intend," "may," "plan," "potential," "predict," "project," "future," "will," "seek," "foreseeable," the negative version of these words, or similar terms and phrases may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking.

Non-GAAP measures Liquidity Adjusted for IPO Proceeds is a non-GAAP metric and is defined as Cash and Cash Equivalents plus Short-Term Investments plus Long-Term Investments plus the net proceeds received in our IPO in April 2026. We believe this non-GAAP financial measure provides useful supplemental information to investors about our financial condition and liquidity. Management uses this measure to evaluate our operating performance, formulate business plans, assess our overall liquidity position, and make strategic decisions. This non-GAAP financial measure should be considered in addition to, not as substitutes for, the most directly comparable GAAP measure. This measure has limitations as an analytical tool and is not standardized under GAAP. Other companies may not use this measure or may define similar measures differently. Therefore, our non-GAAP financial measure may not be directly comparable to similarly titled measures used by other companies.
