Nebius Group stock has delivered a very large 236.6% return over the past year, yet its broader valuation checks lean expensive, raising a clear tension between recent share price strength and what the fundamentals currently signal.

• Over the past 1 year, Nebius Group is up 236.6%. This puts extra focus on whether the recent run is ahead of what its fundamentals can justify.
• On the opportunity side, large AI infrastructure contracts and new partnership models can support expectations for long term revenue growth. At the same time, heavy capital needs, secured debt facilities and ongoing questions around cash flow timing may limit how much investors are willing to pay for that growth.
• Nebius Group passes only 1 of 6 valuation checks. This suggests the stock is not a clear bargain on the broader set of metrics even after recent volatility.

The issue now is whether Nebius Group's strong share price performance already reflects the growth investors are paying for, or if there is still room for upside before the valuation looks stretched.

Is Nebius Group a Bargain on Earnings?

The P/E ratio is a useful way to look at Nebius Group because it already generates positive earnings, so you can compare what investors pay for each dollar of profit against other software stocks. Nebius Group trades on about 61.9x earnings, which is well above both the Software industry average of roughly 28.6x and the peer group average of about 37.8x. On simple comparisons, the stock is priced at a premium.

However, a more tailored fair P/E ratio for Nebius Group, which factors in its business mix, risk profile and growth expectations, is estimated at around 70.1x. That sits meaningfully above today’s multiple and suggests the current share price does not fully reflect the level of earnings investors might be prepared to pay for within this framework. Despite large AI contracts, hefty capital plans and recent secured debt raising keeping risk firmly in view, the market P/E still sits below what this model implies.

On this P/E multiple, Nebius Group stock appears undervalued relative to the fair ratio benchmark.

The Bottom Line

Nebius Group screens as undervalued on the tailored P/E multiple, yet its low broader value score underlines that this is only one supportive signal among several weaker checks. That mix points to a stock where expectations for growth and margins already matter as much as any simple valuation gap. From here, the key question is whether Nebius Group can turn heavy investment and funding needs into durable, high quality earnings, or whether those cash demands end up justifying the current discount rather than closing it.
