Nebius Group (NasdaqGS:NBIS) is back in focus after Nvidia disclosed a 9.3% equity stake and a US$2b investment tied to large scale AI data center plans, which is spotlighting Nebius’s AI cloud infrastructure positioning.

Nebius Group’s share price has pulled back sharply in the short term, with the 1 day, 7 day and 30 day share price returns all declining. However, the 90 day share price return is up 20.19% and the year to date share price return is up 88.65%. The 1 year total shareholder return is very large and the 5 year total shareholder return is up 151.32%. This points to strong longer term momentum that recent Nvidia related gains and fresh debt and partnership announcements have not fully sustained.

The recent swing in Nebius Group’s share price leaves a key issue on the table. Are investors reassessing the company’s AI infrastructure cash flows and new business model, or has sentiment simply run ahead of fundamentals as valuation stretches?

Most Popular Narrative: 30.9% Undervalued

The most followed Nebius Group narrative pegs fair value at $245.43, which sits well above the last close at $169.69, and frames recent volatility against long run cash flow potential under an 8.62% discount rate.

Heavy capital expenditures for new GPU deployments and data centers are expected in the coming years. If industry trends around digital emissions and environmental regulation become more strict, Nebius could face elevated costs for power, sustainability, and compliance, potentially depressing net margins and overall returns on invested capital.

Want to see why this narrative still arrives at a higher fair value for Nebius Group? It leans on assumptions of aggressive top line expansion, shrinking margins, and a rich future earnings multiple that assumes the AI cloud build out keeps paying off.

Result: Fair Value of $245.43 (UNDERVALUED)

However, this narrative could still be undermined if rising data center and compliance costs squeeze Nebius Group margins, or if larger cloud competitors limit its long term pricing power.

Another View on Nebius Group’s Valuation

The fair value narrative points to Nebius Group trading 30.9% below an estimated value, yet the current P/E of 59.1x already sits well above the US Software industry at 29.3x and peers at 38.8x. The fair ratio sits even higher at 72.2x, which implies the market could still stretch further. That gap cuts both ways, so this may represent either a valuation cushion or a lot of expectation already priced in.
