Nvidia Backed SB Energy’s $50 Billion Valuation Push. Wall Street Just Hit the Brakes
SB Energy, backed by SoftBank and Nvidia, has delayed its IPO plans, which were targeting a $50 billion valuation. The company's $4.9 billion debt package has seen weak demand with yields around 10%. Nvidia has invested $1.5 billion and committed another $1.5 billion tied to the IPO. American Electric Power (AEP) is involved through a regional power partnership. Nvidia's exposure includes a $105 billion guarantee under certain conditions.
