John Carrington, Chief Executive Officer of Stem, commented, “We are excited to complete this business combination, which will accelerate the next phase of Stem’s growth and further extend our leadership position in AI-driven clean energy storage systems. We continue to benefit from strong, sustainable macro tailwinds as the world deepens its commitment to de-carbonization.
