Davidson & Co., Compass Point and Northland Capital Markets are acting as co-managers for the proposed offering.The company intends to list its Class A common stock on the Nasdaq Global Market under the ticker “SDIG.”The miner’s operations are powered through the reclamation of coal refuse sites across Pennsylvania. The company removes coal waste from piles and burns it in an “emissions-controlled manner” at its facilities.The environmental impact of crypto mining has been at the forefront of investors’ concerns because the industry requires a large amount of energy to power its operations.Another miner, Gryphon Digital Mining, which is going public through the reverse takeover of Sphere 3D, said it’s planning to create “the world’s largest fully integrated pure play bitcoin miner with zero carbon footprint.”
