STPK
Star Peak Energy Transition Corp
A blank-check company, or SPAC, set up by asset manager Magnetar Capital to find a business in the clean-energy world to buy. In 2021 it merged with Stem, an energy storage firm whose Athena software uses AI to decide when batteries should charge and discharge. The merged company took the name Stem, and its shares began trading under a new ticker that same spring.
