SB Energy Delays IPO Amid Growing Investor Skepticism Over AI Data Center Boom

SB Energy Inc., the SoftBank-backed developer of a large data-center project in Ohio, has postponed its IPO slated for this month. Bankers could not attract enough buyers at the targeted valuation of more than $50 billion, pushing the expected listing to “mid- to late October.”
