Generac's Amazon Deal Could Be Worth Up to $8 Billion

Generac shares surged after the backup-power maker signed a supply agreement with Amazon worth an initial $2.4 billion — a figure that could climb to as much as $8 billion if Amazon exercises additional commitments.

The deal, announced for Amazon's data centers, also carries a familiar feature of big tech procurement contracts: warrants. Generac has granted Amazon's subsidiary the right to buy up to roughly 1.69 million shares at a purchase price of $200.93 per share, according to the source report.

The agreement covers what Generac knows best: backup power generators for Amazon's data centers. But the Amazon contract is not the company's first major win in the segment. By late July 2026, Generac had already signed two multiyear supply agreements with hyperscale customers. The first covered nearly $700 million of equipment scheduled for delivery in 2027. Generac signed the second in June 2026, though product-specific terms for 2027 and 2028 were still being finalized at the time.

The backlog tells the story. 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 to nearly $450 million.

A Company Built in 1959, Remade for the AI Era

Founded in 1959, Generac now operates across a broad energy-technology ecosystem. Its residential segment sells home standby generators, portable generators, and microinverters, while also touching energy storage and management. The commercial and industrial arm covers 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.

The market has noticed. GNRC stock carries a market capitalization of about $12 billion and is up 51% year to date.

Not a Generic Generator Vendor

Generac is offering data-center operators something more specific than a standard standby generator. The company is positioning itself as an integrated power systems supplier for facilities where a brief interruption can disrupt thousands of servers and expensive artificial intelligence workloads.

Its product range now includes five new generators with output spanning from 2.25 MW to 3.25 MW. Generac pairs those generators with battery storage, inverters, controls, paralleling systems, and service support. That structure gives customers a single supplier for a larger part of the power chain rather than a collection of separate equipment vendors.

The strategy is paying off in order flow. A $2.4 billion anchor commitment from Amazon — with up to $8 billion in potential upside — sits on top of a $1.6 billion data-center backlog and two earlier hyperscale agreements. If Amazon exercises its warrants and additional commitments, the deal would cement Generac's shift from a residential generator maker into a core supplier for AI infrastructure power.
