Management Comments

• Simon Irish, CEO of Terrestrial Energy: "Our IMSR plant excels in its capacity to be adapted and customized to market needs in a grid congested world. Amerescos proven track record in energy system integration creates a powerful platform to develop IMSR plant projects that meet the emerging requirements of rapidly growing demand for reliable, carbon-free energy across multiple industrial sectors."
• Nicole Bulgarino, President of Federal Solutions and Utility Infrastructure at Ameresco: "Our collaboration with Terrestrial Energy reflects our commitment to expanding the capabilities of our clean energy portfolio. By exploring hybrid energy systems that leverage the IMSR plants heat and power output, were enhancing our ability to deliver reliable, cost-effective, and sustainable solutions tailored to the evolving needs of data centers and industrial customers."

Industry Context

This collaboration highlights the increasing demand for reliable, carbon-free energy solutions, particularly for energy-intensive sectors such as data centers and industrial applications. It positions Terrestrial Energy's advanced nuclear technology (Generation IV Small Modular Reactor) as a flexible solution capable of integrating with existing energy infrastructure, like natural gas, to meet both immediate and long-term decarbonization goals. The partnership with Ameresco, an established energy solutions provider, reflects a broader industry trend towards comprehensive, integrated energy solutions rather than standalone power generation. The focus on SMRs addresses challenges like grid congestion and the need for distributed, customized energy supply.

Comparison to Industry Standards

• Terrestrial Energy's IMSR is highlighted as the first Generation IV reactor design to complete Canada's CNSC Vendor Design Review, setting a significant regulatory benchmark for advanced reactor technologies.
• Unlike conventional Light Water Reactor technology, the IMSR's thermal, steam, and electric supply systems are remote and isolated from regulated nuclear systems, allowing for unique customization and hybridization with other energy systems, such as natural gas, to meet site-specific needs.
• The IMSR's capacity to supply zero-carbon, high-temperature thermal energy for high-efficiency, low-cost electric power generation and direct industrial process heat use extends nuclear energy application far beyond traditional electric power markets, differentiating it from many existing nuclear solutions.

Stakeholder Impact

• Shareholders (HCM II): Will vote on the Business Combination; their shares will convert to shares in the combined company listed on Nasdaq. Potential for value appreciation if the combined entity performs well, but also risk from redemption requests.
• Customers (Data Centers, Industrial): Will benefit from customized, scalable, reliable, clean, and cost-competitive energy solutions, including the potential for early electricity delivery via an energy bridge.
• Employees (Terrestrial Energy & Ameresco): Potential for increased project activity and growth opportunities due to the expanded collaboration and business combination.
• Suppliers: Terrestrial Energy's strategy leverages existing nuclear industry supply capabilities, potentially benefiting current and future suppliers.

Next Steps

• Site identification for IMSR plant projects across the United States.
• IMSR plant project development, design, licensing, construction, and operation.
• Filing of Registration Statement on Form S-4 with the SEC by HCM II and Terrestrial Energy.
• SEC declaration of effectiveness of the Registration Statement.
• Mailing of definitive proxy statement/prospectus to shareholders of HCM II and Terrestrial Energy.
• Completion of the Business Combination.
• Listing of the combined company on Nasdaq under the ticker symbol IMSR.
