Holtec Nuclear Files for Nasdaq IPO with 300 MW SMR-300 Modular Reactor

Holtec Nuclear Corporation filed its initial public offering with the U.S. Securities and Exchange Commission (SEC) on July 10, 2026, aiming to finance the deployment of its SMR-300 modular reactor, a 300-megawatt (MW) pressurized water model. The company will trade on Nasdaq under the ticker HNUC.

The offering is led by J.P. Morgan, Guggenheim Securities, Goldman Sachs, Citigroup, and BofA Securities as lead underwriters, with Morgan Stanley, Cantor, BMO Capital Markets, and Oppenheimer as co-underwriters, according to the company's official statement dated July 10. The offering size and price per share have not yet been determined, per the S-1 filing.

The SMR-300 is designed to be faster and cheaper to build than a conventional reactor: the company estimates three years of construction on a 6-hectare site and expects regulatory approval for deployment in 2029. The first two units, Pioneer 1 and 2, will be installed at the Palisades nuclear site in Michigan in the early 2030s.

The IPO is underpinned by substantial federal support. The U.S. Department of Energy (DOE) awarded a $1,520 million loan for the restart of the Palisades plant (the first reactivation of a shuttered commercial reactor in U.S. history) and a $400 million grant for the construction of the first two SMR-300 units, according to a Canary Media report dated July 15.

The company recorded revenues of $165.3 million in the first quarter of 2026 and net income of $17.8 million, per the S-1 filing. Holtec, headquartered in Camden, New Jersey, operates in more than 12 countries and competes with NuScale Power, X-energy, and GE Hitachi in the modular reactor segment.

Holtec's public market debut will serve as a benchmark for the valuation that public markets assign to modular reactor technology, at a moment of renewed institutional investor interest in nuclear generation as a firm, carbon-free power source. Final pricing has yet to be set.
