Generac Holdings

Generac Holdings

Robert Kern founded Generac in 1959 in a Waukesha, Wisconsin garage, initially producing portable generators for Sears under the Craftsman label. The company remained family-controlled for decades, transitioning to public markets in 2010 under the leadership of CEO Aaron Jagdfeld, who had joined the firm in 1994 as a controller. The wealth generated from Generac's rise to dominate the North American home standby generator market — where it commands roughly 70% market share — remains primarily held by the Kern family and long-tenured executives. Generac operates as an industrial company that deploys capital directly through acquisitions rather than traditional fund structures. The firm's strategy targets adjacency expansion: using free cash flow from the mature residential and commercial generator business to acquire companies in energy storage, solar microinverters, smart thermostats, and grid-services software. Notable acquisitions include Pika Energy (battery storage, 2019), Enbala Power Networks (grid optimization software, 2020), Chilicon Power (solar microinverters, 2021), and ecobee (smart thermostats, 2021). The geographic footprint extends across North America, with manufacturing in Wisconsin and South Carolina, and a growing presence in Europe through the acquisition of PR Industrial and Off Grid Energy. The product stage spans from legacy internal-combustion generators to early-stage deployment of residential battery storage systems competing with Tesla Powerwall. The professional team exceeds 8,000 employees globally, with manufacturing capacity spread across multiple US facilities as well as operations in Mexico and Italy. In May 2023, Generac acquired a minority stake in Wallbox, a Barcelona-based EV charging company, as part of a global commercial agreement to distribute bidirectional EV chargers through Generac's existing residential dealer network. The Kern family's philanthropic vehicle, the Kern Family Foundation, operates independently and focuses on K-12 education reform and character development, granting over $50 million annually (per public filings, 2022). Generac's structural differentiator is its installed base moat: over 5 million generators already connected to US homes create a distribution and service network that no pure-play clean-tech startup can replicate. The firm crosses the industrial-energy divide by using the high-margin, recession-resistant revenue from generator sales and maintenance contracts to finance a multi-decade transition toward distributed energy resources, all while remaining a publicly traded operating company with no external limited partners or fund-duration constraints.
