Shares of ASP Isotopes Inc. (ASPI) experienced a significant surge of 15.64% in the past 24 hours, following the announcement of a $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 sparked 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 performance reflects growing confidence in ASP Isotopes' strategic direction and its potential to capitalize on opportunities in the evolving nuclear energy landscape.
