Nebius Group N.V. (NBIS) Faces Dilution Concerns Despite Strong AI Demand

Fred Alger Management, an investment management company, released its "Alger Spectra Fund" third-quarter 2026 investor letter. The letter can be downloaded here. During the third quarter of 2026, U.S. equities delivered modest gains, with the S&P 500 advancing 2%. Despite robust corporate earnings and resilient consumer spending, market breadth remained weak as 60% of S&P 500 constituents closed lower. Against this backdrop, the fund lagged the Russell 3000 Growth Index. Class A shares of the fund returned 0.29% without a sales charge and -4.98% with sales charges, compared to 0.45% for the index. Consumer Discretionary and Tech drove the relative performance, whereas Communication Services and Utilities dragged. Macro headwinds weighed on sectors like Energy following oil supply disruptions. On the short side, a position in an IT consulting firm detracted from returns, while a short in an advertising technology company generated positive gains following its weak earnings report and rising competitive threats. Amid these shifting dynamics, the fund continues to prioritize disciplined stock selection to capture long-term opportunities across the expanding AI ecosystem.

Alger Spectra Fund stated the following regarding Nebius Group N.V. (NASDAQ:NBIS) in its Q3 2026 investor letter

"Nebius Group N.V. (NASDAQ:NBIS) is an AI cloud infrastructure company that builds and operates data centers equipped with advanced processors used to develop and run AI applications. Shares detracted from performance during the quarter, extending a pullback from their early-summer record high. Although the stock rallied after Nebius reported better-than-expected results, it retreated when the company announced plans to raise additional capital through debt that can later convert into equity, raising concerns that existing shareholders' ownership would be diluted. A broader selloff in AI infrastructure stocks later in the quarter added to the pressure. Despite the recent share price weakness, we believe the company's fundamentals remain strong given solid demand for its computing capacity and its position as a leading independent provider of AI computing power."
