Generac

Generac grew net sales by 11% year on year to $1.17 billion, though 9% year on year on an organic basis. Commercial and industrial sales drove much of the increased revenue as that segment saw sales climb 29% year on year, despite the headwinds in the residential segment.

Why it matters: Management maintained full-year overall sales guidance but now expects commercial and industrial sales to grow in the low-30s on a year-on-year percentage basis. Data centers continue drive commercial and industrial sales higher given its strong order book and backlog. Generac recognized more than $100 million of revenue and secured two multiyear supply agreements with hyperscale customers, and it expects to recognize nearly $450 million in data center revenue in 2026. Backlog stands at $1.6 billion thanks to new orders of $1 billion. Data centers remain key to the debate over Generac's stock. While backlog doesn't include new orders from the second hyperscale customer, we hesitate to ascribe too much value to them as Generac doesn't make its own engines, though the Enercon acquisition strengthens its solutions.

The bottom line: We lift our fair value estimate for narrow-moat rated Generac to $215 per share from $212 on strong commercial and industrial guidance, though with some offsets in lower residential shipments. Even so, home standby generators returned to growth thanks to favorable price-cost dynamics. While we don't see the data center business as moaty—Generac's moat relies on a strong brand in its home standby generator business—Generac has been investing in vertical integration to reduce lead times of needed equipment and to sell its high-margin products as part of its solution. We maintain our High Uncertainty Rating for Generac. We continue to see a wide range of outcomes. Hyperscale purchase orders are likely the largest upside case for the stock, though how long favorable price/cost dynamics persist in the home standby generators is another question.

We lift our fair value estimate for narrow-moat-rated Generac to $215 from $212 on strong commercial and industrial guidance, though with some offsets in lower residential shipments. Even so, home standby generators returned to growth thanks to favorable price-cost dynamics. Ultimately, we think data centers will help Generac double commercial and industrial product sales by 2028, up from 2025 levels.

In Generac’s legacy generator businesses, we view its home standby segment as its most profitable and valuable. The company has seen a sharp increase in sales in recent years due to elevated power outages. We forecast sales to plateau at around $2 billion per year over our forecast period.

On a consolidated basis, we forecast a five-year revenue CAGR of roughly 13%, driven by commercial and industrial sales growth as data center sales scale. We forecast EBITDA margins to expand to nearly 21% at midcycle from 17% in 2025, owing to operating leverage on higher sales.

We assign Generac a narrow moat rating underpinned by a strong brand and cost advantages in its home standby generators business.

Generac’s brand is synonymous with the home standby generator category—akin to Kleenex in facial tissues. The company’s market share in the category is about 75% today and has been over 70% for the last decade, a testament to its moat. In contrast to adjacent markets (residential solar equipment providers, for example), we perceive there to be higher levels of end-customer brand awareness with home generators.

As the largest player in a market with limited penetration, Generac views itself as responsible to drive market growth. Through its robust advertising, Generac generates customer leads, which it in turn supplies to its dealer network. In addition, the company has its own proprietary selling system, PowerPlay, which is used by the company’s largest-volume dealers. Dealers use the system for quote generation, customer presentation, and relevant follow-up. We believe Generac’s ability to supply customer leads and its PowerPlay selling system create loyalty from its network of dealers, making them less likely to sell a competing brand.

We believe Generac’s outsize share in the home generator category results in a maintainable cost advantage over competitors. In particular, we think the company benefits from scale in buying power, economies of scope (widest range of products/distribution), and advertising and marketing.

With market share 4 times the size of the next-largest competitor, Generac benefits from scale in buying power, in our view. In comparing prices, Generac is on par with or slightly below competitor offerings. We think this is the result of management’s desire to increase adoption in the category rather than an inability to extract higher pricing. Despite offering prices comparable to or below peers, the company claims to have the highest margins in the industry, supporting its cost advantage over peers.

Generac’s scale give it economies of scope over competitors. The company offers residential standby generators ranging in capacity from 7.5 kilowatts to 150 kilowatts, which we believe is the widest range in the industry. Offering a wide product set allows its dealer base and customers to find the product that meets each home’s needs. In addition, Generac’s breadth and depth of its distribution network is unmatched in the industry. The company distributes its products via an omnichannel distribution network including factory direct to dealers (majority of sales), industrial distributors, national/regional retailers, and e-commerce. This breadth of distribution ensures customers looking for a home generator are bound to find a Generac. Additionally, the depth of the company’s dealer network (over 8,000) is by far the largest in the industry.

Generac’s scale in the industry allows it an unmatched advertising budget among peers. We believe the company’s focus on advertising (and subsequent customer lead generation) is central to Generac’s competitive advantage. Generac spent approximately 11.5% of its 2024 sales on selling and service. We believe this amount of spending was nearly equivalent to the total home standby sales of its next-largest competitor, highlighting the difficulty competitors have in matching Generac’s advertising spending.

In addition to residential generators, Generac sells portable generators and energy storage for residential applications and a broad array of commercial and industrial generator products. Given it does not enjoy the same size of share in these markets, we do not believe it possesses a moat in these segments.
