Generac Reports Q3 Earnings With $1.6 Billion Data Center Backlog After Amazon Deal

Generac Power Systems reports third-quarter results on October 28, its first earnings report since disclosing a backup power deal with Amazon, with a data center backlog of roughly $1.6 billion. 247wallst reported the earnings date and the backlog figure.

Generac's Amazon Deal and the Backlog

Generac, founded in 1959 and headquartered in Waukesha, Wisconsin, makes backup power generators and energy technology. In mid-September, the company disclosed a long-term agreement to supply backup generators for Amazon's data centers, with initial deliveries in 2027 and 2028. Management described a second hyperscale agreement as "at least as big as the first hyperscaler agreement that we announced or bigger."

Amazon grew AWS revenue 37% last quarter and now expects about $220 billion in 2026 cash capital expenditures, according to 247wallst. Generac's data center backlog of roughly $1.6 billion leaves out that second hyperscale customer. Last quarter, adjusted earnings per share of $2.91 exceeded the $2.0118 consensus by 44.65%, while revenue of $1.17 billion came in slightly below estimates. Commercial and Industrial sales rose 29% and Residential fell 2%. About $71 million in tariff refunds drove gross margin up to 44.5%.

Generac's Data Center Commitments

According to akta.pro company records, Generac signed a global supply agreement with a leading hyperscale data center operator in June 2026 to deliver large-megawatt backup power generators, with approximately $600 million in 2027 deliveries committed and a data center product backlog exceeding $700 million. The same records show Generac launched its SD Series large-megawatt diesel generators, the SD1250, SD1500 and SD3250 at 1.75 to 3.25 megawatts, for mission-critical data center, healthcare and infrastructure applications. Generac's annual revenue was $4.21 billion in FY2025.

Generac's Earlier Data Center Moves

In October 2026, Zacks reported that Generac shares had surged 57.8% year to date, driven by data center growth and a $2.4 billion Amazon backup generator deal, with Commercial and Industrial revenue up 29% to $556 million in the second quarter. In October 2026, BizTimes covered an exclusive interview with Generac CEO Aaron Jagdfeld about the company's $8 billion deal with Amazon. In October 2026, Yahoo reported that Baird's Small/Mid Cap Growth Strategy highlighted Generac in its second-quarter 2026 investor letter, citing long-term demand for resilient power infrastructure from AI data centers, chip fabs and grid constraints.

Generac's Factory and Guidance Timeline

Generac's Sussex, Wisconsin, plant was set to begin production by the end of the third quarter of 2026. Management held full-year adjusted EBITDA margin guidance at 18.5% to 19.5% before refunds and outlined a path to triple assembly capacity from its $1.25 billion target within 12 months.
