Use of proceeds:

• Working Capital and General Corporate Purposes: X-Energy, Inc. estimates net proceeds of approximately USD 693.8 million from the base offering, based on an assumed offering price of USD 17.50 per share (the midpoint of the indicated price range). X-Energy intends to use all of the net proceeds from this offering to purchase newly issued Common Units from XERC at a price per unit equal to the public offering price per share of Class A common stock, less underwriting discounts and commissions. In turn, XERC intends to deploy these proceeds for working capital and other general corporate purposes, which may include research and development activities, sales and marketing, general and administrative expenses, and capital expenditures.
• Technology Commercialization and Project Execution: A significant portion of the proceeds is expected to be directed toward advancing the commercialization of the Xe-100 reactor design and the TRISO-X fuel fabrication facility (TX-1), including ongoing regulatory engagement with the NRC, design finalization, engineering, procurement, and construction activities associated with the Dow ARDP project. Management has indicated that the company has sufficient near-term liquidity from its current cash position of approximately USD 458.9 million in cash and cash equivalents, USD 304.9 million in short-term investments, and USD 261.5 million in long-term investments as of December 31, 2025, combined with the IPO proceeds, to continue operations and fund its near-term project milestones.
• Future Capital Requirements: Management acknowledges that additional capital will be required beyond the proceeds of this offering to fully execute its long-term business plan, including scaling fuel fabrication capacity, licensing subsequent TRISO-X facilities, and pursuing further commercial reactor deployments. The company expects to fund these requirements through a combination of future issuances of debt or equity securities, continued government cost-share reimbursements, and revenues generated from technology licensing and services agreements. Until deployed, any unused proceeds may be invested in short-term, investment-grade, interest-bearing instruments to preserve liquidity.
• Tax Receivable Agreement (TRA) Obligations: In connection with the offering, X-Energy, Inc. will enter into a Tax Receivable Agreement with XERC and its continuing equity owners. Under the TRA, the company is expected to pay approximately 85% of anticipated future tax savings — estimated at approximately USD 641.5 million over 15 years — to the TRA Holders. These obligations may reduce cash otherwise available for reinvestment or other corporate uses. Should the company elect to terminate the TRA immediately following the offering, the estimated lump-sum termination payment would be approximately USD 439.3 million.

Dividend Policy:

X-Energy, Inc. does not expect to declare or pay any cash dividends on its common stock for the foreseeable future. Management intends to retain all available capital and future earnings to fund ongoing research and development, support commercialization of the Xe-100 reactor and TRISO-X fuel, advance key projects such as the Dow ARDP demonstrator, and address general corporate needs. Any future dividend decisions will remain subject to the sole discretion of the Board of Directors, applicable provisions of Delaware corporate law, and any restrictive covenants contained within the company’s existing or future financing arrangements. Accordingly, prospective investor returns are expected to be driven principally by capital appreciation rather than recurring dividend income.

X-Energy, Inc. – Business Model, Technology Platform and Strategic Positioning

• Integrated Advanced Nuclear Platform with Asset-Light Revenue Model: X-Energy operates an intellectual property-driven business model centered on two core technology pillars: the Xe-100 HTGR and proprietary TRISO-X pebble fuel. Critically, X-energy does not construct, own, or operate nuclear facilities, significantly reducing the capital intensity of its model. Revenue is expected to be generated from technology licensing fees for the use of the Xe-100 design, project planning and construction support services, regulatory advisory and procurement support, long-term operations and maintenance services over the anticipated 60-year life of each facility, and fuel fabrication services for the supply of TRISO-X fuel. Approximately 15–35% of reactor line revenue is expected to be realized prior to or at commercial operations date (COD), with approximately 65–85% derived from recurring post-COD services, providing meaningful long-term revenue visibility.
• Flagship Xe-100 Reactor – Purpose-Built for Industrial and Power Applications: The Xe-100 is a fourth-generation, high-temperature gas-cooled reactor designed around inherent passive safety features, eliminating the need for active cooling intervention even in an emergency. Its modular design delivers scalable output from 80 MWe per unit to 320 MWe in a four-pack configuration. The reactor’s ability to deliver high-temperature process heat (up to approximately 565°C) positions it as a viable decarbonization tool for industrial sectors such as chemicals, hydrogen production, and manufacturing — markets difficult to serve with intermittent renewable energy. The Xe-100 also features a significantly smaller safety exclusion zone (400 meters versus 16 kilometers for traditional large nuclear plants), enabling co-location with industrial customers and dense power demand centers including data centers.
• TRISO-X Proprietary Fuel as a Competitive Moat: X-Energy is one of the few companies globally with a licensed and operational TRISO fuel fabrication facility. TRISO-X pebble fuel is engineered to be non-melting by design, incorporating multiple ceramic and carbon-based protective layers that serve as the primary containment barrier. X-Energy was selected to receive one of the first allocations of High-Assay Low-Enriched Uranium (HALEU) from the DOE, a critical prerequisite for fuel production. The proprietary nature of TRISO-X fuel — combined with X-Energy’s intent to be the sole initial supplier for Xe-100 customers — creates a captive, recurring fuel revenue stream throughout the estimated 60-year lifecycle of each deployed reactor. X-Energy also holds the potential to supply TRISO fuel for third-party advanced reactor designs, broadening the commercial addressable market for its fuel business.
• Anchor Commercial Partnership with Dow Chemical under the ARDP: X-Energy’s most advanced commercial deployment is the Dow ARDP Project, a first-of-a-kind Xe-100 four-pack installation (up to 320 MWe equivalent) intended to supply process heat and power to Dow’s Seadrift, Texas manufacturing site. This project benefits from a 50/50 cost-share arrangement with the DOE, with total estimated project costs of approximately USD 2.4 billion and DOE commitment of approximately USD 1.2 billion. The Construction Permit Application has been docketed with the NRC for an 18-month review, representing one of the shortest CPA timelines in history — a significant regulatory validation milestone. X-Energy has received approximately USD 438 million in ARDP reimbursements to date and continues to advance engineering, procurement, and construction planning activities.
• International Expansion via Strategic Partnerships: Beyond the U.S., X-Energy has signed a non-binding Joint Development Agreement (JDA) with Centrica plc of the United Kingdom to explore the deployment of Xe-100 reactors for industrial and grid-scale energy applications. The Xe-100 has been positioned as part of the U.K. government’s “third leg” nuclear strategy for advanced and innovative reactors, complementing large-scale plants and Gen III+ SMRs. Additionally, X-Energy has a strategic partnership with DL E&C, a leading Korean engineering and construction firm, to support global deployment. Management anticipates these international partnerships will expand its pipeline of potential reactor deployments and diversify its long-term customer base.
• Strong Government Support and Policy Tailwinds: The company benefits from significant and sustained U.S. government support for advanced nuclear energy. The One Big Beautiful Bill Act, signed in July 2025, maintained tax credits for nuclear projects initially introduced under the Energy Policy Act of 2005 and expanded under the Inflation Reduction Act. In May 2025, the U.S. President issued four Executive Orders supporting the acceleration of regulatory review for advanced reactors and promoting a domestic nuclear supply chain. Additional congressional appropriations of USD 3.1 billion to the ARDP have been made, a portion of which management expects to be allocated to X-Energy’s award. These policy tailwinds meaningfully reduce commercialization risk and enhance long-term demand visibility. 

X-Energy, Inc. – Industry Landscape, Structural Growth Drivers and Competitive Positioning

• Large and Growing Market for Advanced Nuclear Energy: Global electricity demand is accelerating driven by AI, cloud computing, electrification, and industrial reshoring. Nuclear energy — particularly next-generation SMRs and HTGRs — is increasingly recognized as an indispensable source of firm, zero-carbon, baseload power. Advanced reactors such as the Xe-100 are designed to serve both power generation and industrial decarbonization markets, addressing sectors that cannot be practically served by intermittent renewables. Hyperscale technology companies, industrial operators, and utilities are actively seeking long-term clean power solutions with firm capacity, creating substantial commercial demand for X-Energy’s technology.
• Data Center and AI Infrastructure as a Near-Term Demand Catalyst: The explosive growth of AI and cloud computing is driving unprecedented electricity demand from hyperscale data centers. The Xe-100’s modular, scalable design and ability to co-locate near demand centers position it as an attractive solution for technology companies requiring reliable, zero-carbon firm power. X-Energy has highlighted data centers as a key target market, and management expects strong corporate interest from technology sector customers as they face regulatory, sustainability, and reliability constraints on power procurement.
• Industrial Decarbonization as a Structural Long-Term Driver: Industries such as chemicals, hydrogen production, steel, and advanced manufacturing require high-temperature process heat that renewable energy cannot efficiently deliver at scale. The Xe-100’s ability to supply approximately 200 MWth of thermal output at temperatures up to 565°C makes it one of the few advanced nuclear designs purpose-built for deep industrial decarbonization. As carbon pricing regimes tighten and corporate net-zero commitments accelerate, demand for high-temperature, low-carbon process heat is expected to grow substantially, reinforcing the long-term commercial opportunity for the Xe-100.
• Competitive Differentiation via Passive Safety and Smaller Footprint: Compared to traditional large-scale nuclear and Gen III+ light water SMRs, the Xe-100’s HTGR design offers structural competitive advantages including inherent passive safety (no active cooling systems required), a dramatically reduced safety exclusion zone (400 meters versus 16 kilometers for conventional nuclear), and a compact modular footprint approximately one-quarter to one-tenth that of a traditional nuclear plant. These attributes reduce siting constraints, lower permitting complexity, and enable deployment closer to industrial customers, differentiating X-Energy favorably within the advanced nuclear technology landscape.
• Favorable Regulatory Momentum and NRC Precedent: The NRC’s docketing of the Construction Permit Application for the Dow Project within an 18-month review timeline — among the shortest ever accorded to a nuclear application — represents a meaningful regulatory validation of X-Energy’s technology and approach. The company has also engaged the NRC on licensing for additional TRISO-X fuel fabrication facilities (TX-1 and beyond). Strong ongoing engagement with the DOE through the ARDP has built institutional credibility and further derisks the first commercial deployment.

Financial Highlights (Results of Operations) (Expressed in USD)

• Revenue Scale and Composition: X-Energy reported total revenues and grant income of approximately USD 120.2 million for fiscal year 2025, compared with USD 109.1 million in fiscal year 2024, representing a year-over-year increase of approximately 2%. Revenues are primarily derived from services contracts performed under the ARDP Agreement and other government and commercial research and development agreements. Services revenue was USD 83.9 million in fiscal year 2025 (versus USD 94.3 million in 2024), while grant income increased meaningfully to USD 36.2 million (versus USD 14.8 million in 2024), reflecting accelerating ARDP milestone activity. The company has not yet generated commercial revenues from technology licensing, fuel sales, or long-term services agreements, as these revenue streams remain contingent on successful reactor deployment and fuel commercialization.
• Operating Loss Profile: X-Energy recorded an operating loss of approximately USD 123.5 million in fiscal year 2025, an improvement from an operating loss of approximately USD 170.3 million in fiscal year 2024. Total operating expenses declined to USD 243.7 million in fiscal year 2025 from USD 279.4 million in fiscal year 2024, driven by lower direct costs of USD 130.1 million (versus USD 161.4 million in 2024) and modestly reduced selling, general and administrative expenses of USD 111.9 million (versus USD 116.3 million in 2024). Management expects future operating losses to increase as the company scales its development and commercialization activities.
• Net Loss and Pre-IPO Capital Structure Dynamics: Net loss for fiscal year 2025 was approximately USD 126.0 million, compared with a net loss of approximately USD 389.8 million in fiscal year 2024. The significantly higher 2024 net loss was substantially driven by approximately USD 239.3 million of other income (expense) items, primarily reflecting non-cash fair value adjustments on pre-IPO financial instruments, including warrant liabilities and preferred equity. Interest expense increased to USD 16.2 million in fiscal year 2025 (versus USD 0.5 million in 2024), reflecting the company’s growing debt obligations as it funded its expanding development program.
• Liquidity and Balance Sheet Position: As of December 31, 2025, X-Energy held cash and cash equivalents of approximately USD 458.9 million, short-term investment balances of USD 304.9 million, and long-term investment balances of USD 261.5 million. Total assets were approximately USD 1.21 billion as of December 31, 2025, compared with USD 579.5 million at year-end 2024, reflecting capital raises during the period. On a pro forma basis following the IPO, total assets are expected to be approximately USD 1.90 billion and total liabilities are expected to decline to approximately USD 91.9 million, as pre-IPO mezzanine equity instruments convert to shareholders’ equity.
• Path to Profitability and Ongoing Capital Requirements: X-Energy remains pre-revenue from its commercial nuclear business and continues to operate at a significant loss. Management acknowledges that the company will require additional funding beyond IPO proceeds to fully fund its path to commercial reactor deployment, fuel fabrication scale-up, and long-term services revenues. The company expects to fund these needs through a combination of IPO proceeds, continued ARDP cost-share reimbursements, and future issuances of debt or equity. Achieving profitability is contingent on successful commercialization of the Xe-100, execution of the Dow ARDP project, and entry into technology licensing and fuel supply agreements with commercial customers.

Key Management Highlights

Risk Associated (High)

Investment in the initial public offering of X-Energy, Inc. (XE) is subject to several material risk factors, including the following:

• Pre-Revenue and Pre-Commercialization Stage: X-Energy has not yet generated revenues from commercial reactor deployments, technology licensing, or fuel supply agreements. The company’s current revenue is derived almost entirely from government cost-share contracts, primarily the ARDP. There is no assurance that the Xe-100 will be successfully commercialized, that customers will accept anticipated fee structures, or that the company will achieve profitability. Investors should be aware that the company is at an early development stage with significant execution, technical, and market risks ahead.
• Dependence on the ARDP Agreement and U.S. Government Funding: A majority of X-Energy’s current revenues are derived from the ARDP Agreement with the DOE. Extensions of the ARDP beyond the current budget period (through August 2026) are subject to DOE discretion, congressional appropriations, and compliance with program requirements. Termination or material reduction of ARDP funding would significantly impair the company’s revenue base, accelerate cash burn, and may require additional dilutive financing on potentially unfavorable terms.
• Key Project Concentration Risk – Dow ARDP Project: The Dow ARDP project is X-Energy’s most advanced and highest-profile commercial deployment and serves as the primary validation vehicle for the Xe-100 technology. Any significant delay, cost overrun, regulatory setback, or failure by Dow to make a positive final investment decision would materially and adversely affect X-Energy’s ability to commercialize its technology, generate revenues, and maintain investor confidence. The project involves significant first-of-a-kind construction and regulatory risks.
• Technology Development and Regulatory Execution Risk: The Xe-100 and TRISO-X fuel are first-of-a-kind technologies with limited operational history at commercial scale. NRC licensing for both the Dow project reactor and the TX-1 TRISO-X fuel fabrication facility involves complex and extended regulatory review processes. Delays in design finalization, materials qualification, facility construction, or regulatory approvals could materially set back the company’s commercialization timeline and increase capital requirements.

Conclusion

X-Energy, Inc. presents a investment proposition for risk-tolerant investors seeking exposure to the advanced nuclear energy sector, supported by meaningful structural tailwinds including surging electricity demand from AI and data centers, industrial decarbonization imperatives, and a favorable U.S. government policy environment. The company’s dual technology platform — the Xe-100 HTGR and proprietary TRISO-X pebble fuel — is differentiated by inherent passive safety, industrial heat capability, modular scalability, and a captive fuel revenue model that creates potential for long-duration recurring income over the 60-year lifecycle of each deployed reactor. The Dow ARDP project is advancing through NRC permitting with notable speed, and approximately USD 438 million in DOE reimbursements to date, combined with strong institutional interest anchored by ARK Investment Management’s indicated USD 105 million participation, lend credibility to the platform. X-Energy’s experienced leadership team, highly qualified workforce, and deep regulatory relationships provide meaningful operational and execution support. The company ended fiscal year 2025 with approximately USD 1.0 billion in combined cash and investment balances, providing near-term liquidity runway. However, there are significant risks including the pre-commercialization stage of the business, near-total dependence on government contract revenues, concentration risk in the Dow ARDP project, the ongoing need for substantial additional capital, and material uncertainty regarding the timeline and economics of the first-of-a-kind Xe-100 commercial deployment.

Hence, given the early-stage nature of the business, the strategic importance of the technology platform, the support of the U.S. government, and the associated execution and commercialization risks, “X-Energy, Inc. (XE)” IPO seems “Attractive” at the IPO price, aligned with the advanced nuclear energy sector.
