Generac stock jumps 40%: What’s behind the after-hours rally?

Economic Times 2 hrs ago·17 Sept 2026, 6:07 am

Generac Holdings saw its shares climb more than 40% in after‑hours trading after the company revealed a multi‑year agreement to supply backup generators for Amazon’s data‑center operations, a contract that could be worth as much as $8 billion.

The deal gives Generac a foothold in the fast‑growing cloud‑infrastructure market, where reliable power is critical. Securing a customer of Amazon’s scale can boost the firm’s revenue visibility and may improve margins, as the equipment is high‑value and often sold with service contracts.

Investors will be watching how quickly Generac can ramp up production and meet delivery schedules, as well as any updates on the contract’s timeline or additional customers in the data‑center space. Future earnings releases and guidance revisions will indicate whether the partnership translates into sustained growth.
