Nebius Shares Sink 16% as Neocloud Issues Disappointing Full-Year Outlook Amid Tech Sector Headwinds

Nebius shares sank 16% on Thursday as one of the biggest publicly traded neoclouds issued disappointing full-year revenue guidance, casting a shadow over a sector that has recently experienced extreme volatility and intense market scrutiny regarding the massive capital investments required for artificial intelligence infrastructure.

The sharp pullback in the company’s stock price comes on the heels of a massive wave of enthusiasm that had temporarily lifted neocloud shares earlier in the week. Prior to the Thursday report, companies in the space had enjoyed a robust rally on Wednesday, propelled by stronger-than-expected financial updates from industry peers CoreWeave and IREN. During Wednesday’s trading session, CoreWeave surged nearly 25%, Nebius climbed 15%, Applied Digital rose more than 7%, and IREN added nearly 6%. Those gains had offered a welcome reprieve for investors following weeks of steep selloffs driven by growing concerns over the financial sustainability of the broader artificial intelligence buildout. However, the optimism proved short-lived as Nebius delivered its third-quarter financial results and forward-looking guidance ahead of the opening bell, dragging down premarket shares across the wider neocloud ecosystem.

According to the official financial statement released by the company, Nebius experienced explosive top-line growth during the third quarter, with revenue jumping 571% compared to the same period a year earlier. Despite the massive percentage increase in revenue, the company still reported a net loss of $37.5 million, which translates to a loss of 13 cents per share. While representing a negative bottom line, this performance marked an improvement over the previous year’s figures, when Nebius posted a net loss of $119.6 million, or 50 cents per share.

Despite the strong quarterly revenue growth, Wall Street analysts focused heavily on the company’s future projections and surging capital expenditure plans. In a letter to shareholders, Nebius CEO Arkady Volozh revealed that the company expects fiscal year 2026 revenue to land at the low end of its previously established range of $3 billion to $3.4 billion. This cautious stance compared unfavorably to the consensus estimate of $3.37 billion compiled by analysts surveyed by LSEG.

Looking further ahead, Nebius provided its initial outlook for fiscal year 2027, projecting revenue between $12 billion and $13 billion. In the shareholder letter, the company noted that this target reflects a conservative approach to the pace of its infrastructure buildout. That projected range came in roughly in line with Wall Street expectations, slightly edging past the LSEG consensus of $11.98 billion.

At the same time, the financial commitment required to reach those revenue targets has escalated dramatically, unnerving investors who are already jittery about capital efficiency in the AI sector. Nebius announced that it expects fiscal year 2026 capital expenditures to reach $27 billion. This figure represents an upward revision from its previous capex guidance of $20 billion to $25 billion and easily surpasses the FactSet consensus expectation of $23.85 billion. Furthermore, the company’s preliminary guidance for fiscal year 2027 anticipates capital expenditures between $40 billion and $45 billion, blowing past the FactSet expectation of $28.77 billion.

The financial anxieties surrounding Nebius and its peers are unfolding against a backdrop of broader market and corporate turmoil. The stock move also coincides with the sudden resignation of Nvidia CEO Jensen Huang, following stinging revelations regarding multiple extramarital affairs, including one involving an alleged Chinese spy. Nvidia has played a foundational role in shaping the neocloud market, acting as both a primary technology supplier and a financial backstop by investing directly in these companies and supporting their infrastructure projects. According to a regulatory filing at the end of June, Nvidia held approximately $329 million in Nebius shares, underscoring the deep structural ties between the semiconductor giant and the neocloud providers powering the AI revolution.

The financial pressure on neocloud financing models has been further highlighted by movements in the debt markets. Just last week, CoreWeave’s bond yields spiked past the 16% mark, signaling heightened risk perceptions among fixed-income investors. During its earnings report on Tuesday, CoreWeave informed analysts that it intends to keep parent-level debt financing under $5 billion through 2027. By comparison, Nebius disclosed during the quarter that it had successfully raised $5.75 billion in debt financing to fund its operations and expansion plans.

Addressing investors and analysts during an earnings conference call, CEO Arkady Volozh sought to reassure the market about the long-term viability of the sector despite current financial hurdles and macroeconomic uncertainty.

"Capital markets have been unsettled lately," Arkady Volozh said on the conference call. "Two questions are being asked our whole industry: how fast can AI build-out happen, and who will pay for it? These are important questions. The way I think about it is simple. The demand for AI is real and substantial. Everything else, like building the capacity and financing it, is just a task. Tasks can be hard, but they all can be solved."

Compounding these financial and market challenges, neocloud providers are also navigating an increasingly complex political and regulatory landscape as they race against rivals to secure land and power for new data center infrastructure. The political backdrop has added a distinct layer of volatility. In recent electoral cycles, local communities and voters have pushed back against the rapid physical expansion of digital infrastructure. Last week, U.S. voters supported dozens of local ballot initiatives designed to restrict or halt the development of new data centers in various regions. Simultaneously, political shifts in Washington, where Democrats won sweeping victories in both houses of Congress, have introduced fresh policy variables for capital-intensive technology industries to monitor.

Despite these regulatory headwinds, executive commentary from across the sector has consistently maintained that fundamental demand continues to outstrip available supply, keeping the pressure on companies like Nebius to aggressively scale their operations even as financial markets demand greater capital discipline.
