Generac Holdings (GNRC) stock: Winston Score and insider trades
Generac makes backup power generators and energy storage systems. Its products keep the lights on when the electricity grid goes down — for homeowners, businesses, and industrial facilities. Generac is the largest residential generator brand in the United States, selling through hardware stores, electrical contractors, and dealers. The company earns most of its revenue by selling hardware — generators, batteries, and related equipment — with additional income from installation services and parts. Generac operates primarily in North America but has been expanding into Europe and other markets through acquisitions. Its main competitive advantage is brand recognition and a large dealer network built over decades. The biggest growth driver is rising demand for home energy storage and solar-plus-battery systems, but the business is also heavily tied to weather events and power outages, meaning sales can swing sharply from year to year depending on storm activity.
