The company has backing from Sam Altman and Department of Energy pilot programs. Shares trade at approximately $97 with twenty-one analysts assigning buy ratings.

The average price target stands at $103 but some analysts have set targets as high as $175. This implies potential 81% gains if commercialization succeeds.
