It intends to use such net proceeds to (i) purchase Class A Interests from Holtec International at a per interest purchase price equal to the per share price paid by the underwriters for the Class A common stock and (ii) cause Holtec International to use the net proceeds for general corporate purposes, which may include accelerating SMR-300 licensing, deployment and manufacturing capacity, furthering commercialization of the Holtec Green Boiler and HI-THERM HCSP innovations, and expanding product and services offerings in emerging areas such as cybersecurity and national defense programs.
