Winston Score History

The full picture

X-Energy is a nuclear energy company that designs small, advanced nuclear reactors and produces the special fuel they need to run. Its main product is the Xe-100, a small modular reactor (SMR) that can generate heat and electricity for power utilities, industrial factories, and government facilities. The company also makes TRISO-X fuel, a type of nuclear fuel pellet that is considered safer and harder to melt down than traditional nuclear fuel.

X-Energy makes money through government contracts, research grants, and development agreements — it does not yet sell reactors commercially. Most of its work is based in the United States, and it has received significant funding from the U.S. Department of Energy. The company has a potential edge because it is one of very few firms with both a reactor design and its own fuel production capability, but it is still pre-revenue in a meaningful sense, and the biggest risk is how long it takes to get regulatory approval and build its first commercial reactor.
