In the past year, shares of the company have gained 34.1% compared with the Zacks Manufacturing-General Industrial industry’s growth of 3.5%.

Factors at Play Ahead of GNRC’s Q2 ResultsGenerac entered second-quarter 2026 against a backdrop of increasing momentum in its Commercial & Industrial (C&I) segment, driven by robust data center demand, while Residential trends remain more back-half weighted.

Management guided to second-quarter consolidated net sales growth of approximately 9% to 10% year over year, with growth entirely driven by the C&I segment. On the last earnings call, the company highlighted that it was in the final stages of vendor approval with two hyperscale customers. It has also been witnessing backlog expansion for these products with both current and new customers.

Generac’s data center backlog reached more than $700 million at the first quarter-end, representing a roughly $300 million increase since mid-February and providing visibility into 2027 deliveries. Importantly, this number excludes a nonbinding notice to proceed for $600 million in hyperscale data center deliveries expected in 2027, indicating substantial upside potential as the pipeline converts into firm orders. The company has been focused on capacity expansion for large megawatt generators to support accelerating demand.

Within the Residential segment, meaningful growth is skewed toward the second half of 2026, driven by home standby generator, supported by easier comparisons.

Within residential energy technology, ecobee has been emerging as a strategic asset, with more than 5 million connected homes and increased energy services and subscription sales. With the integration of PWRcell 2, PowerMicro microinverter and next-gen standby generators with ecobee, Generac aims to create a differentiated residential energy ecosystem.

Generac expects second-quarter adjusted EBITDA margins to be 18%, representing modest year-over-year expansion. Margin improvement is expected to accelerate in the back half of the year, driven by operating leverage on higher volumes and contributions from the Enercon acquisition.

Nonetheless, volatile macroeconomic conditions, including tariff troubles, stiff competition and increasing operating costs remain additional concerns for Generac.

Heavy reliance on the residential business exposes Generac to weather-driven volatility. Further, data center market expansion brings its own set of concerns. With increasing reliance on this end market, Generac is exposed to cyclical capital spending cycles in AI and data centers. Any delays in manufacturing capacity expansion could also weigh on growth targets.

Also, Residential energy growth in 2025 was largely driven by Puerto Rico’s energy grant-related program. However, with the completion of the program, energy storage systems declined in the first quarter. GNRC is also recalibrating its investments and expects the solar and storage market to contract in 2026 due to reduced U.S. federal incentives.

Key HighlightsOn June 15, 2026, Generac announced an expansion of its packaging capacity for large-megawatt generators through the acquisition of a new facility in Belvidere, IL.

On June 2, 2026, Generac announced a supply agreement with a major hyperscale data center operator to provide backup power generators for its data center infrastructure following a comprehensive qualification and audit process.
