Goodwin Advises Helion on $465 Million Series G Financing to Accelerate Commercial Fusion Deployment

The Technology team advised Helion, a fusion energy company, in its $465 million Series G financing round led by Thrive Capital, with participation from new and existing investors. The financing, which values Helion at $15.5 billion post-money and brings the company’s total funding to date to $1.5 billion, will support the acceleration of commercial fusion deployment, expansion of manufacturing capacity, and growth of the company’s ability to deliver clean electricity to customers. The financing follows several recent technical milestones achieved by Helion’s Polaris prototype and continued development of Orion, the company’s first fusion power plant currently under construction in Washington.

Helion is a fusion energy company focused on generating zero-carbon electricity from fusion. Its mission is to build the world’s first fusion power plant, enabling a future with unlimited clean electricity.

The Goodwin team was led by David Brekke, Amy Kim, Daisy Ramos Garcia, and Sam Boomgaarden.
