TradeUp Global’s (TUGC) shareholders have approved the SPAC’s merger with SAITECH Limited, an energy-saving bitcoin mining operator and cleantech developer. TradeUp said that the deal is expected to close by the end of April. The combined company’s stock will trade on Nasdaq under the symbol SAI. SAITECH provides hosting for bitcoin mining servers. Its proprietary cooling and waste energy recovery technology also allows for waste heat from mining to be used as recycled energy heat. The companies announced plans to merge in late September through a deal that pegged SAITECH with an equity value of around $228M.
