TRISO-X Fuel – Intrinsic Safety (1) The Department of Energy describes TRISO fuel as “the most robust nuclear fuel on Earth” It retains waste and fission products within the fuel during all foreseeable adverse conditions, even worst-case accidents, and it is designed not to melt • X-energy manufactures its own proprietary TRISO encapsulated fuel (“TRISO-X”) to ensure supply & quality control. TRISO Fuel has a 60+ year demonstrated track record through prototype and full-scale reactors • HALEU-based fuel like TRISO-X increases burnup and efficiency, which decreases costs • Because TRISO-X Fuel IS a containment vessel and is designed not to melt, the Xe-100 does not require large, expensive concrete & steel containment structures • The low reactor power density and self-regulating core design means that if cooling stops, the core naturally shuts down. This prevents the reactor from melting under foreseeable adverse conditions and requires no operator actions under such adverse conditions • Physics, not mechanical systems, ensures safety Fuel Process Step 1 Step 2 Step 3 Step 4 èèè ~15.5% Enriched Uranium TRISO Fuel Particle TRISO-X Fuel Pebble Pebble Bed Kernel (~1mm Diameter) (60mm Diameter) >200,000 pebbles form the Feedstock sourced from core of each Xe-100 reactor Uranium kernel encased in ~18,000 TRISO particles per third parties carbon and ceramic layers pebble set in graphite matrix 1) Source: Office of Nuclear Energy – TRISO Particles: The Most Robust Nuclear Fuel on Earth (July 2019) © 2023 X-Energy Reactor Company, LLC, all rights reserved 17

Risk Factors 1) Our business requires substantial investment. At the time of proposed business combination announcement, the aggregate capital raised from the Series C-2 Financing and PIPE Financing will be sufficient to satisfy the minimum cash condition for the transaction; however, the commitments will not be sufficient to finance the total capital required for the business plan. To the extent we have significant redemptions in connection with this proposed business combination or are unable to raise the level of capital we contemplate as part of the proposed business combination, we will be required to make significant adjustments to our business plans in light of our available capital resources. For example, we will have to reduce future costs, which could materially impact our business plan, including potentially deferring our TRISO-X fuel fabrication facility, not pursuing some of our other strategic objectives and/or limiting the resources available to further develop our design, sales and manufacturing efforts. 2) Our corporate expenditures, including our corporate level outspend, are subject to numerous risks and uncertainties, including uncertainties related to the impact of inflation, evolving regulatory requirements, raw material availability, global conflicts, global supply chain challenges and component manufacturing and testing uncertainties, among other factors. Accordingly, it is possible that our overall cash outspend could be higher than the levels we currently estimate, and any increases could have a material adverse affect on our business, financial condition and results of operations. 3) In order to fulfill our business plan, we may require additional funding. To the extent we require additional funding in the future, such funding may be dilutive to our investors and no assurances can be provided as to terms of any such funding. Any such funding and the associated terms will be highly dependent upon market conditions and the progress of our business at the time we seek such funding. 4) If we fail to manage our growth effectively, we may be unable to execute our business plan and our business, results of operations, and financial condition could be harmed. 5) We have not yet delivered the Xe-100 or any other SMR to customers and have not achieved final investment decisions for any of our reactors. Any setbacks we may experience during our first commercial delivery planned for 2029 and other demonstration and commercial missions or failure to obtain final investment decisions could have a material adverse effect on our business, financial condition and results of operation, and could harm our reputation. 6) We will depend on pre-sales revenue to fund our demonstration, corporate growth and commercial development. Any delays in the development and manufacture of our SMRs and related technology may adversely impact our business and financial condition. 7) The amount of time and funding needed to bring our nuclear fuel to market at scale may greatly exceed our expectations. 8) We depend significantly on U.S. government contracts, which often are only partially funded, subject to immediate termination, and heavily regulated and audited. Continued full funding of the Advanced Reactor Demonstration Program (“ARDP”) is also subject to future government appropriations and continued political support. The termination or failure to fund, or negative audit findings for, one or more of these contracts or the ARDP program could have an adverse impact on our business, financial condition, results of operations and cash flows. 9) We and our customers operate in a politically sensitive environment, and the public perception of nuclear energy can affect our customers and us. 10) Accidents involving nuclear power facilities, including but not limited to events similar to any of the Three Mile Island, Chernobyl or Fukushima Daiichi nuclear accidents, or terrorist acts or other high profile events involving radioactive materials, could materially and adversely affect the public perception of the safety of nuclear energy, our customers and the markets in which we operate and potentially decrease demand for nuclear energy or facilities, increase regulatory requirements and costs or result in liabilities or claims that could materially and adversely affect our business. 11) The market for SMRs generating electric power and high-temperature heat is not yet established and may not achieve the growth potential we expect or may grow more slowly than expected. 12) There is limited operating experience for reactors of this type, configuration and scale, which may result in greater than expected construction cost, maintenance requirements, operating expense or delivery timing. 13) Competition from existing or new companies could cause us to experience downward pressure on prices, fewer customer orders, reduced margins, the inability to take advantage of new business opportunities, and the loss of market share. 14) We rely on a limited number of suppliers for certain materials and supplied components, some of which are highly specialized and are being designed for first-of-a-kind or sole use in the Xe-100 and Xe-Mobile. We and our third party vendors may not be able to obtain sufficient materials or supplied components to meet our manufacturing and operating needs, or obtain such materials on favorable terms. 15) The Xe-100 and Xe-Mobile designs have not yet been approved nor licensed for use at any site by the NRC or the Canadian Nuclear Safety Commission, and its approval or licensing of these designs is not guaranteed. 16) Even if the Xe-100 and Xe-Mobile are licensed in the United States and Canada, we must still obtain approvals on a country by country basis to deploy these reactor technologies, which approvals may be delayed or denied or which may require modification to our design. 17) The cost of electricity generated from nuclear sources may not be cost competitive with other electricity generation sources in some markets, which could materially and adversely affect our business. 18) Changes in the availability and cost of electricity, natural gas and other forms of energy are subject to volatile market conditions that could adversely affect our business. 19) We are part of the nuclear power industry, which is highly regulated. Our fuel designs differ from fuels currently licensed and used by commercial nuclear power plants, and our SMR designs similarly differ from reactors currently in operation. As a result, the regulatory licensing and approval process for our nuclear power plants and others that operate with our nuclear fuels may be delayed and made more costly, and industry acceptance of our nuclear fuels may be hampered. 20) The operations of our planned fuel facility in Tennessee, and any future facilities, will be highly regulated by the U.S. federal and state-level governmental authorities, including the NRC as well as the State of Tennessee and the other jurisdictions in which we may establish operations. Our operations could be significantly impacted by changes in government policies and priorities. 21) We must obtain governmental licenses to possess and use radioactive materials, including isotopes of uranium, in our fuel facility operations. Failure to obtain or maintain, or delays in obtaining, such licenses could impact our ability to fabricate TRISO-X fuel for our customers, who will be initially reliant on us for fuel, and have a material adverse effect on our business, financial condition and results of operation. 22) We must complete nuclear grade material qualifications and obtain regulatory approvals for the use of various materials in our TRISO-X fuel and our reactor designs. This includes long lead time irradiation testing and analysis, which may require redesign or use of alternative suppliers if results are unsatisfactory. Further, certain key nuclear grade materials and components, such as graphite, are only produced in limited quantity and predominantly outside of the United States. Cultivating expanded foreign or domestic U.S. supply chain manufacturing capacity for key materials and components depends on cooperation from government and supply chain partners that may result in shortages and delays if not accomplished within assumed timelines or costs. 23) Our operations involve the use, transportation and disposal of toxic, hazardous and/or radioactive materials and could result in liability without regard to fault or negligence. 24) If we are unable to access high-assay low-enriched uranium (“HALEU”), our ability to manufacture TRISO-X fuel will be adversely affected, which could have a material adverse effect on our business, financial condition and results of operations. Historically, Russia has been a significant global supplier of HALEU, but due to the ongoing war in Ukraine and associated U.S. sanctions, we are highly dependent on the U.S. government for access to HALEU. 25) We are subject to stringent U.S. export and import control laws and regulations. Unfavorable changes in these laws and regulations or U.S. government licensing policies, our failure to secure timely U.S. government authorizations under these laws and regulations, or our failure to comply with these laws and regulations could have a material adverse effect on our business, financial condition and results of operations. 26) Our business is subject to the policies, priorities, regulations, mandates and funding levels of multiple governmental entities and may be negatively or positively impacted by any change thereto. 27) The U.S. government’s budget deficit and the national debt, as well as any inability of the U.S. government to complete its budget or appropriations process for any government fiscal year could have an adverse impact on our business, financial condition, results of operations and cash flows. 28) Our customers could incur substantial costs as a result of violations of, or liabilities under, environmental laws. 29) Changes in tax laws could adversely affect our business prospects and financial results. 30) We rely on intellectual property law and confidentiality agreements to protect our intellectual property. We also rely on intellectual property we license from third parties. Our failure to protect our intellectual property rights, our infringement of third party intellectual property or our inability to obtain or renew licenses to use intellectual property of third parties, could adversely affect our business. 31) We are subject to information technology and cyber security threats which could have an adverse effects, including regulatory effects, on our business and results of operations. 32) A pandemic, epidemic or outbreak of an infectious disease in the United States or worldwide, including the outbreak of a novel strain of coronavirus ( COVID 19 ), could adversely affect our business operations and our financial results. 33) Uncertain global macro-economic and political conditions could materially adversely affect our results of operations and financial condition. 34) We depend on key executives and management to execute our business plan and conduct our operations. A departure of key personnel could have a material adverse effect on our business. 35) Our business plan requires us to attract and retain, qualified personnel including personnel with highly technical expertise. Were we not to be able to successfully recruit and retain experienced and qualified personnel, it could have a material adverse effect on our business. 36) As a growth-oriented company, our securities have been subject to downward pressures in recent months, including inflationary pressures, increases in interest rates and other adverse economic and market forces, which may result in high redemptions of the cash available from the trust fund. If there are substantial redemptions, there will be a lower float of our common stock outstanding, which may cause further volatility in the price of our securities and adversely impact our ability to secure financing following the closing of the proposed business combination.
