SPAC/IPO details
A unit bundles the listed securities. Its components may become separately tradable after a period specified in the prospectus, even before a business combination. Units still outstanding at the business combination are generally separated into their components. Check the relevant SEC filings for the timing and procedure.
Only whole warrants can be exercised; fractional warrants per unit require multiple units to make a whole warrant. Warrants commonly allow holders to buy shares after a business combination at a set exercise price, often USD 11.50. They often last up to five years but may be redeemed earlier. Exercise date, price and term can differ; consult the relevant SEC filings.
Terrestrial Energy is a developer of Generation IV nuclear plants that use its proprietary Integral Molten Salt Reactor (IMSR) technology. IMSR technology captures the full transformative operating benefits of molten salt reactor technology in a plant design that represents true innovation in cost reduction, versatility and functionality of nuclear energy supply. IMSR plants will supply zero-carbon, reliable, dispatchable, low-cost, high-temperature industrial heat and electricity for a dual-use energy role relevant to many industrial applications, such as chemical synthesis and desalination. In so doing, they extend the application of nuclear energy far beyond electric power markets. IMSR plants have the potential to make substantial contributions to industrial competitiveness, energy security, and economic growth. Their deployment will support rapid global decarbonization of the primary energy system across a broad spectrum. Terrestrial Energy uses an innovative design, together with proven and demonstrated molten salt reactor technology, which offers a unique set of operating characteristics to deliver high and compelling commercial potential. Terrestrial Energy is engaged with regulators, suppliers and industrial partners to build, license and commission the first IMSR plants in the early 2030s.
