Shares of Generac Holdings (NYSE:GNRC) fell 11% on Wednesday as the company hosted its 2026 Investor Day, with the decline coming even as management disclosed strengthening demand in its data center business.
Investor disappointment centered on the absence of a long-term contract with a hyperscaler that market participants had been expecting. The stock slipped roughly 10% midway through the presentation as hopes for an announcement of a major agreement remained unfulfilled, and the full session closed with an 11% decline.
Despite the market reaction, Generac reported that its backlog for data center products rose by about 75% over the past six weeks, a figure management highlighted as evidence of growing demand in that end market. The company framed the data center opportunity as a strategic growth area and made that sector a focal point of the investor day presentation.
Management left its 2026 guidance unchanged. The company reiterated expectations for revenue growth in the mid-teens, with residential sales projected to increase by around 10%. Commercial and industrial revenue is forecast to expand in the low- to mid-20% range. EBITDA margin guidance for 2026 remained at 18%-19%.
Market commentary included an observation from William Blair analyst Brian Drab, who said: "We believe the pullback offers a buying opportunity."
The investor day emphasized Generac's positioning within the data center industry, which management linked to rising investment in artificial intelligence and cloud computing infrastructure. That broader sector backdrop was presented as a driver of demand for Generac's data center products, even as investors weighed the company's near-term contract visibility.
Summary
Generac's shares declined during its 2026 Investor Day after no hyperscaler deal was announced. Management highlighted a roughly 75% increase in data center backlog over six weeks and confirmed 2026 guidance, including mid-teens revenue growth and an 18%-19% EBITDA margin target.
