Generac Holdings makes backup power generators for residential, commercial and industrial customers, along with other power equipment, the largest manufacturer of backup power generators in the United States. Its home standby generator business has grown as more homeowners seek protection against power outages, whether from severe weather events, aging electrical grid infrastructure or increasingly frequent extreme weather linked to climate patterns. Generac's generators automatically switch on during power outages to keep essential home systems running, a product category that has seen growing demand alongside increased awareness of grid reliability issues in various regions. The company's revenue and growth are tied to the frequency and severity of power outage events, along with broader consumer and business willingness to invest in backup power infrastructure as insurance against future grid disruptions.
