"We are proud to complete the combination of Star Peak and Stem, establishing Stem as the first pure-play smart energy storage company to go public in the US. We are more confident than ever in Stem’s significant value, offering investors a unique ESG opportunity to invest in a pure play clean energy company that’s helping to revolutionize the electric grid. I look forward to continued partnership with John and the world-class Stem team as we drive further growth and success over the long-term," Michael Morgan, Star Peak Chairman.
