ASP Isotopes Inc. (ASPI) stock surged 12.05% in pre-market trading on Friday, building on the previous day's gains following the announcement of a significant $22 million loan agreement with TerraPower, a leading U.S. nuclear innovation firm. The deal, aimed at supporting the construction of a new uranium enrichment facility, has ignited strong investor enthusiasm for the Delaware-based company's future prospects in the nuclear energy sector.

According to the agreement signed on May 16, 2025, TerraPower will provide conditional financial commitments totaling $22 million to ASP Isotopes' subsidiary, QLE TP Funding SPE LLC. The loan, guaranteed by ASP Isotopes Inc. and Quantum Leap Energy LLC, carries a maturity date of May 16, 2032. This financial backing is intended to facilitate the production of High Assay Low-Enriched Uranium (HALEU), a crucial component for advanced nuclear reactors.

The deal also includes a long-term supply arrangement, allowing ASP Isotopes to sell excess HALEU to other buyers if TerraPower doesn't meet certain purchase criteria. This flexibility, combined with the substantial loan amount, suggests a potentially lucrative future for ASP Isotopes in the growing market for advanced nuclear fuel. Investors appear to be reacting positively to this development, viewing it as a significant step forward for the company's growth and market position in the nuclear energy industry. The stock's impressive pre-market performance reflects growing confidence in ASP Isotopes' strategic direction and its potential to capitalize on opportunities in the evolving nuclear energy landscape.
