    Nebius Group (NBIS) Could Be 25% Undervalued Following Strong Q2 AI Infrastructure Growth

    Listen to the news

    Nebius Group (NasdaqGS:NBIS) is back in focus after a strong second quarter, with AI infrastructure revenue and large contracts drawing attention to how the company is using capital and what that might mean for the stock.

    Nebius Group’s share price has had a volatile year, with a 1 month share price return of 9.86% and a year to date share price return of 132.55%, even after a 19.73% decline over the past 90 days and a 4.26% drop in the last session.

    That kind of swing has kept attention on the story behind the move rather than just the latest tick. The second quarter AI infrastructure results and the recent multi billion dollar convertible bond offerings appear to be key reference points for how investors are weighing growth potential against funding costs and dilution risk.

    Looking beyond the trading screens, the total shareholder return of 206.18% over the past year and 165.29% over five years points to a stock where sentiment has already shifted significantly. This is why each new contract, capital raising and read through on AI infrastructure demand is being scrutinised so closely.
