Nebius Drops 13%: Capital Expenditure Concerns and Related Market Sell-Off

Sharp Decline Triggered by Earnings and Spending Surge

Nebius Group experienced a significant drop in its share price on Friday, tumbling to approximately $91.19. This sharp decline was accompanied by a dramatic increase in trading volume, which soared to 22.8 million shares—68% higher than the typical daily average. The sell-off was directly linked to the company’s recent quarterly results, which not only fell short of revenue expectations but also revealed a substantial jump in capital expenditures.

The main surprise came from Nebius’s capital spending. In the December quarter, Nebius reported that its capital expenditures had surged to nearly $2.1 billion, a dramatic rise from $416 million during the same period last year. This spending is being used to fund the expansion of nine new data centers across the United States, France, Israel, and the United Kingdom. For a company operating in the fast-moving AI infrastructure sector, this level of investment creates immediate funding pressures and increases the risk profile, making the stock more sensitive to concerns about execution or cash management.

Sector-Wide Impact and CoreWeave’s Influence

Nebius’s decline was not an isolated event. Its shares dropped in tandem with those of CoreWeave, a larger competitor, after CoreWeave released disappointing earnings. By midday Friday, Nebius was down 14.9%, while CoreWeave’s stock had fallen 21.9%. This demonstrates how closely the two companies’ stocks move together, with negative developments at one quickly affecting the other.

The sector’s volatility was further amplified by CoreWeave’s announcement that its capital expenditures for 2026 would more than double those of 2025. Both Nebius and CoreWeave are aggressively expanding their data center footprints, borrowing heavily to finance this growth. This approach has created a high-risk environment, with both companies showing rapid revenue increases but also significant, ongoing losses.

For Nebius, this means facing challenges on two fronts: disappointing its own investors with missed revenue targets and soaring spending, while also being caught in a broader sector downturn as investors question the sustainability of such aggressive investment. The neocloud sector now faces heightened risk, with both companies exhibiting high growth but also high cash burn, leaving them exposed to any negative shifts in market sentiment or operational setbacks.

Looking Ahead: Key Metrics and Upcoming Triggers

The immediate concern for investors is whether the recent sell-off is an overreaction or the beginning of a longer-term decline. A crucial metric to watch is cash conversion—while Nebius finished 2025 with a strong cash position, there is debate about how effectively this cash can be used to generate profitable growth given the rapid pace of expansion. The company’s latest report highlighted heavy capital outlays and a substantial net loss, raising questions about future funding needs.

Another important indicator will be the company’s revenue outlook for 2026. Nebius has projected $3.35 billion in revenue for the year, representing nearly 547% growth. Investors will closely examine the next earnings report to determine whether the company can translate its large investments into sustainable, profitable revenue. Any failure to deliver on this front could lead to further declines in the stock price.

The next major event for Nebius will be its upcoming quarterly report, which will serve as the first real test of whether the company is successfully executing its ambitious nine-site expansion and achieving the rapid growth that investors expect. Until then, the stock is likely to remain sensitive to sector-wide sentiment and any new developments related to spending or cash flow.
