AI cloud computing services provider Nebius (NBIS.US) has announced its financial results for the fourth quarter of 2025. The report revealed that Nebius's Q4 revenue surged 547% year-over-year to $227.7 million; however, this figure fell short of market expectations of $247.5 million. Adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) was $15 million. The adjusted net loss widened to $173 million, a 151% increase compared to the net loss of $69 million in the same period last year. Nebius has established itself as a leading player among "new cloud service" providers. Its core business includes supplying NVIDIA (NVDA.US) GPUs and providing AI cloud services, assisting enterprises in scaling their AI infrastructure. Persistently strong global demand for AI computing power—even major cloud providers like Microsoft and Amazon (AMZN.US) are facing shortages—has led to a surge in demand for Nebius and its main competitor, CoreWeave (CRWV.US). Nebius has gained prominence through several high-profile AI infrastructure supply agreements with US hyperscale companies, including a $17 billion partnership with Microsoft and a $3 billion order from Meta (META.US). Notably, on Thursday, Nebius announced plans to build a new 240-megawatt data center in Béthune, France. Upon completion, it is set to become one of the largest data centers in Europe. The company's Chief Communications Officer, Tom Blackwell, stated that the project will involve converting a former Pirelli tire factory. It is expected to be commissioned in phases, with the first facilities becoming operational by late summer, and approximately half of the capacity available by the end of 2026. Although the financial terms of the project have not been disclosed, a data center of this scale is anticipated to require an investment of several billion euros.
