U.S. stocks saw Nebius Group (NBIS) shares decline 1.4% during Thursday's early trading session, following the company's announcement that it has completed pricing for a $3.75 billion debt and equity issuance aimed at funding its artificial intelligence infrastructure expansion. The offering comprises $2.75 billion in convertible preferred notes and a $1 billion public offering of Class A common stock.

The raised capital will support data center expansion and computing power procurement initiatives, building upon the group's previously announced $17.4 billion artificial intelligence infrastructure partnership agreement with Microsoft (MSFT).
