Nebius Group N.V., the Amsterdam-based AI cloud provider, has been at the center of swirling market action and investor debate this week, as the company prepared to release its much-anticipated fourth-quarter and full-year 2025 earnings. The company’s stock, trading under the ticker NBIS, has seen dramatic swings in the lead-up to its earnings call, reflecting both the promise and the uncertainty that surround its ambitious expansion in artificial intelligence infrastructure.
On February 11, 2026, Nebius shares closed at $88.61, down 3.46% from the previous session, with trading volume surging to roughly 13.9 million shares—about 5% above the average daily figure, according to MarketBeat. The stock’s price fluctuated between $87.14 and $94.75 during the day, underscoring the volatility that’s become typical for AI-focused equities in recent months. Yet, by the morning of February 12, the stock had clawed back a modest 0.4% in premarket trading, edging up to $88.98 as investors braced for the company’s earnings announcement and webcast scheduled for 8:00 a.m. Eastern.
This turbulence comes amid a broader sell-off in AI software stocks, as reported by The Motley Fool, with investors spooked by concerns over heavy spending on data centers and the potential for business disruption. Still, the long-term prospects for AI remain robust. Over the past three years, the Global X Artificial Intelligence and Technology ETF has posted gains of 109%, a testament to the sector’s resilience despite periodic pullbacks.
Nebius’s business model positions it at the heart of the AI revolution. The company operates dedicated data centers powered by accelerators from industry giants like Nvidia and AMD, renting out computing power to customers who want to run AI workloads in the cloud. This approach allows clients to sidestep the massive upfront costs of hardware while tapping into powerful large language models (LLMs) and managed software services for image generation, model training, and custom AI application development.
Demand for Nebius’s infrastructure is so intense that it’s outstripping supply. The company has inked contracts worth more than $20 billion over the next five years with hyperscalers Meta Platforms and Microsoft. Notably, Microsoft alone has committed between $17.4 billion and $19.4 billion through 2031 to secure Nebius’s data center capacity. According to The Motley Fool, Microsoft’s commercial remaining performance obligations (RPO) stood at a staggering $625 billion as of the second quarter of fiscal 2026, suggesting that further orders for Nebius’s services could be in the cards.
These blockbuster deals have fueled explosive growth. Nebius’s revenue is estimated to have soared 368% in 2025 to $550 million, and analysts expect it to rise more than sixfold in 2026, approaching $3.5 billion. Such numbers help explain why Nebius trades at a lofty 57 times sales—a valuation that some see as justified by its rapid expansion and strong pipeline.
Yet, not all the news is rosy. On February 12, 2026, Nebius stock was trending down by 4.59%, reflecting what Timothy Sykes News described as “adverse market reactions to regulatory challenges.” The company’s recent revenue was reported at $117.5 million, but longer-term trends show a significant decline over the past three and five years, signaling potential headwinds. The pre-tax profit margin stood at 5.3%, and the price-to-book ratio was an eye-popping 537.47—far higher than most peers in the sector. Still, Nebius’s balance sheet appeared robust, with total assets of $3.55 billion and total equity of $3.25 billion, compared to liabilities of just under $295 million.
Investor sentiment, according to Timothy Sykes News, remains a “balancing act.” Optimism about Nebius’s strategic pivots and market alignment is tempered by skepticism over its long-term viability without significant reforms. The stock’s volatility—oscillating from highs of $100 to lows under $90—has only intensified these debates, as stakeholders weigh the company’s capital investments against competitive pressures and shifting market dynamics.
One major development this week was Nebius’s announcement that it would acquire Tavily, a startup specializing in “agentic search” technology. This tech is designed to help AI agents pull up-to-date information directly from the web, potentially enhancing Nebius’s offerings. “This acquisition brings the search layer directly into our stack,” said Roman Chernin, Nebius’s chief business officer. In a February 10 filing, Nebius stated it would pay an upfront cash amount for Tavily, with the possibility of additional payments in cash, Class A shares, or a combination, contingent on performance targets. According to Bloomberg, the deal is valued at $275 million, though Nebius has not officially confirmed the price. The acquisition does not require shareholder approval and is expected to close once standard conditions are met.
For Tavily’s users, the transition appears smooth. “Nothing changes about how you use Tavily today,” wrote founder and CEO Rotem Weiss, assuring customers that API and data policies will remain unchanged for now.
Meanwhile, the analyst community is divided. Morgan Stanley’s Josh Baer maintains a Hold rating on Nebius, while Paul Meeks at Freedom Capital Markets has just initiated coverage with a Buy. As of February 11, 2026, MarketBeat data showed Nebius carrying an average “Moderate Buy” rating, with two Strong Buy, six Buy, one Hold, and one Sell among analysts, and a consensus target price of $142.38. The company’s 50-day and 200-day moving averages hovered around $92.88 and $92.84, respectively, and its market capitalization stood at $22.31 billion with a beta of 3.90, reflecting the stock’s sensitivity to market swings.
Institutional investors have also been active. During the fourth quarter of 2025, several hedge funds and investment firms increased their stakes in Nebius, signaling continued interest from the professional investor community despite the volatility.
Looking ahead, investors are laser-focused on Nebius’s earnings report and guidance. Key questions include whether the company can maintain its breakneck revenue growth without letting infrastructure costs spiral, how quickly Tavily’s technology will be integrated into the platform, and whether customer demand will keep pace with the company’s ambitious spending plans. Risks abound: a weaker-than-expected forecast, rising expenses, or hiccups in GPU supply or data-center expansion could weigh heavily on the stock.
As Nebius prepares to put real numbers behind its 2026 spending plans and the Tavily integration timeline, the stakes couldn’t be higher. With the AI sector at an inflection point and investors hungry for clarity, Nebius’s next moves will be closely scrutinized by both Wall Street and Main Street. For now, the company stands as a bellwether for the broader AI infrastructure boom—a story of big bets, bigger risks, and the relentless pace of technological change.
