Shares of backup-power company Generac (GNRC) soared following its supply agreement with tech titan Amazon (AMZN). Initially pegged at $2.4 billion, the deal has the potential to generate up to $8 billion if Amazon exercises additional commitments. As is increasingly common with these types of deals, Generac has also granted Amazon warrants that allow Amazon's subsidiary to buy up to roughly 1.69 million shares at a purchase price of $200.93 per share.
Generac's expertise lies in backup power generators, and that is what the company will provide to Amazon's data centers. But this was not Generac’s first major data-center success. By late July 2026, the company had already signed two multiyear supply agreements with hyperscale customers. The first included nearly $700 million of equipment scheduled for delivery in 2027, while the second agreement was signed in June 2026, although product-specific terms for 2027 and 2028 were still being finalized at the time. Generac reported a data-center backlog of about $1.6 billion for the second quarter. Management also raised its guidance for 2026 data-center revenue of nearly $450 million.

About Generac Stock
Founded in 1959, Generac currently operates across a much broader energy-technology ecosystem. This includes the company's residential segment, through which it sells home standby generators, portable generators, and microinverters, while also being involved in energy storage and management. Meanwhile, the commercial and industrial segment includes prime-power systems, large diesel generators, natural gas generators, switchgear, and more. The data-center business is the fastest-expanding piece, as Generac now supplies large-megawatt backup generators to data-center operators.
Valued at a market capitalization of about $12 billion, GNRC stock is up 51% on a year-to-date (YTD) basis. Can GNRC stock continue on its winning run with the latest Amazon deal? Let's take a closer look.
www.barchart.com Generac Is Not Trying to Be Generic
Generac is offering data-center operators something more specific than a standard standby generator. The company is trying to become an integrated power systems supplier for facilities where a brief interruption can disrupt thousands of servers and expensive artificial intelligence (AI) workloads. Its product range now includes five new generators with output spanning from 2.25 MW to 3.25 MW. The company also combines generators with battery storage, inverters, controls, paralleling systems, and service support. That gives customers a single supplier for a larger part of the power chain rather than a collection of separate equipment vendors.
Notably, what makes Generac unique is its modularity. Generac’s Modular Power System can connect multiple generator units and add capacity as a facility expands. This is useful because data-center operators often do not know the final size of an AI campus when construction begins. A modular design can reduce the need to install all equipment on day one and allows capacity to be added in stages. The company also says its approach can reduce dependence on large custom switchgear arrangements. That matters in a market where lead times, site constraints, and connection delays can be as important as the generator itself.
Overall, Generac's competitive edge comes from its installed manufacturing base, experience with mission-critical backup power, modular systems, and growing energy-storage capabilities. Cummins (CMI) and Caterpillar (CAT) remain powerful competitors with larger industrial-engine businesses, while Kohler and Mitsubishi (MHVIY) also compete in backup generation. Generac’s advantage is that it is building a wider package around the engine, including batteries, controls, conversion equipment, and service. The risk is that Amazon and other hyperscale customers may gain bargaining power as orders become larger.
Generac Reports a Mixed Q2
Despite reporting impressive growth numbers, especially in terms of earnings, Q2 was a mixed bag for Generac. Net sales rose 11% from the previous year to $1.17 billion but missed consensus estimates. Commercial segment revenue increased 29% to $556 million, while the core residential segment slid 2% to $617 million.
However, earnings jumped 76% year-over-year (YOY) to $2.91 per share, coming in ahead of the consensus estimate of $2.01 per share. That marked the second consecutive quarter showing an earnings beat from the company.
Net cash from operating activities witnessed a sharp growth to $121.2 million in Q2 2026 from $72.2 million. Free cash flow followed a similar trajectory, climbing to $62.9 million from $14.5 million in Q2 2025. Overall, Generac ended the quarter with a cash balance of $264.9 million.
On a longer-term basis, Generac has displayed steady growth, seeing its revenue and earnings rise at solid compound annual growth rates (CAGRs). The stock is also trading at relatively reasonable levels, with the forward price-to-earnings (P/E) ratio of 21.3 times and price-to-sales (P/S) ratio of 2.9 times slightly above the respective sector medians.
