Nebius Group reports first-quarter 2026 results before the opening bell on Wednesday, May 13, and the market is treating the update as a test of whether one of tech’s hottest names can justify the run it has already made. Nebius stock has climbed about 111% year-to-date and more than 527% over the past 12 months, but the shares are still facing a hard question: can the company keep growing fast enough to match the price investors are paying?
Wall Street expects revenue in the high $300 million range and a loss of $0.81 a share for the quarter. That sets up a sharp comparison with Nebius’ fourth-quarter 2025 report, when it missed both earnings and revenue expectations. After a surge that has made the company a $45 billion AI infrastructure player, even a solid report may be read through a higher bar than before.
The stakes reflect how far Nebius has traveled in a short time. The Amsterdam-based full-stack AI cloud operator has rapidly rebuilt itself after sanctions-related disruption, and investors have rewarded the turnaround with a valuation usually reserved for companies with far more established profit records. Nebius announced a landmark contract with Meta, a strategic tie-up with Nvidia and a plan to acquire Eigen AI for about $643 million, all of which helped fuel the move higher.
But the numbers also show why the stock is no longer being judged mainly on story. Nebius’ EV/sales stands at 88, versus a sector median of 4, and its price-to-book ratio is 9 times, compared with 4 times for the sector. That kind of premium leaves little room for disappointment, especially as investors have rotated from buying the narrative to wanting to see cash flow.
For now, Nebius is not a cheap stock on traditional measures, and Wednesday’s report will show whether the business is growing fast enough to hold that premium. If the company can back up its aggressive expansion with stronger revenue and a cleaner loss profile, the rally can keep its footing. If not, the valuation gap is wide enough to punish the shares quickly.
