Nebius stock: 3 red flag hidden in its Q2 earnings release

Nebius NBIS shares soared on Wednesday after the artificial intelligence (AI) infrastructure firm reported blockbuster Q2 earnings that handily surpassed Street estimates.

NBIS posted a more than 5x year-on-year increase in revenue, reinforcing that it’s finding success in converting its massive backlog into realized sales.

Still, a deeper look under the hood reveals several pockets of vulnerability – which warrant taking profit in Nebius stock today instead of chasing the upward momentum.

Versus the start of 2026, the AI infrastructure name is up nearly 150% at the time of writing.

Caution is warranted in buying Nebius stock today

The primary reason to consider trimming exposure to NBIS shares despite the company’s blowout Q2 release is the capital intensity and the velocity of its cash burn.

Nebius recorded US$5.7 billion (approx. $9.9 billion) in capital expenditures for Q2 alone (bringing H1 capex to over US$8.1 billion (approx. $14.2 billion)).

Even with some US$8 billion (approx. $14 billion) in cash on the balance sheet, running an over US$20 billion (approx. $35 billion) annual capex trajectory means Nebius remains dependent on high-yield debt issuance, equipment financing, or equity-dilutive raises to fund hardware acquisition before those assets generate free cash flow.

These risks are particularly significant given Nebius Group is trading a rather stretched 88x sales at the time of writing.

What else warrants profit-taking in NBIS shares

Investors are recommended caution also because NBIS’s hyper top-line growth is not reflected in its bottom line yet.

In Q2, the firm's GAAP net loss from continuing operations actually widened to US$190.4 million (approx. $333.2 million) as expenses more than tripled to US$758 million (approx. $1.3 billion), mostly due to ramping depreciation, energy costs, and front-loaded go-to-market investments made ahead of capacity coming online.

Plus, management noted that 2026 capacity additions are heavily back-end weighted; monetization depends on data center completions, power grid interconnections, and Nvidia delivery schedules.

Any supply-chain hiccup, power delay, or cluster deployment lag in the second half of 2026 could cause revenue bottlenecks while fixed infrastructure costs continue to accrue.

How to play Nebius Group after Q2 earnings release

Nebius has priced in an aggressive path toward a US$7 billion (approx. $12.3 billion) to US$9 billion (approx. $15.8 billion) revenue run-rate target. But a part of today's price action is a mechanical short squeeze rather than fundamental re-evaluation.

When momentum slows and forced short covering runs its course, the stock remains vulnerable to a sharp pullback if broad tech sentiment flips.

On the flip side, however, the current technical setup points to continued gains ahead.

NBIS stock has ripped through its major moving averages (MAs), and its RSI sits in the mid-50s currently – indicating intense buying pressure.

Additionally, Wall Street remains bullish on the AI infrastructure stock for the remainder of 2026 as well. The consensus rating on Nebius sits at Moderate Buy currently, with price objectives going as high as $410.
