Generac Holdings signed a long-term supply agreement with Amazon on September 16 to build backup generators for Amazon data centers. The company told the Securities and Exchange Commission that initial deliveries are expected to total $2.4 billion in 2027 and 2028. The headline figure on the deal is $8 billion. That larger number is a ceiling written into a stock warrant, not an order Amazon has placed.
The Waukesha, Wisconsin manufacturer issued Amazon a warrant for 1,693,745 shares of common stock at an exercise price of $200.9266. Amazon vested 307,954 of those shares immediately. The rest vest in tranches as Amazon pays Generac, and that schedule runs up to $8 billion in aggregate gross payments. The warrant expires on September 16, 2033, which sets the outside term at seven years.
Investors treated the ceiling as the deal. Generac shares traded as high as $239 and settled near $205. The company reported $556 million in commercial and industrial revenue in the second quarter of 2026, up 29 percent from $431 million a year earlier, and projects roughly $450 million of data center revenue for the full year. Its data center backlog stood at $1.6 billion before Amazon signed.
Why It Matters
Standby generation is now a procurement race rather than an afterthought. Amazon Web Services runs 287 data centers and has roughly 200 more planned across 22 countries. Each one needs engine-generator capacity sized to the full IT load. Cummins and Caterpillar have each seen order backlogs and data center revenue nearly double in the past twelve months, so Amazon is buying into a market that is already short.
The warrant is the part worth watching. Amazon took equity priced at $200.9266 a share, below where the stock settled after the announcement. It pays for the rest of that equity by buying generators. The structure hands Amazon a discount on its own supply chain and gives Generac a customer with a direct financial stake in ordering more. It also means the $8 billion figure measures Amazon’s option value, not Generac’s booked revenue.
Generac employs more than 4,800 people at 11 Wisconsin locations, seven of them manufacturing plants. Delivering $2.4 billion of generators across two years asks that base to absorb a step change in output. The company has not said which plants take the work, and it has not published a unit count or a nameplate rating for the sets Amazon ordered.
Critical Perspective
Read the warrant as a control, not a reward. Every tranche past the first 307,954 shares vests on gross payments Amazon itself decides to make, net of offsets Generac did not describe. Amazon therefore sets the pace at which it earns cheap stock in its own supplier, and it owes Generac nothing if it slows down. The filing also grants registration rights and anti-dilution protection, which means the position is built to be sold rather than held. A customer who is also a shareholder with an exit is not the same thing as a partner.
Then there is the capacity question nobody has answered. Generac expects roughly $450 million of data center revenue this year and has agreed to ship $2.4 billion of generators across 2027 and 2028. The company has not named a plant, a shift pattern, an engine supplier or a unit count. Without a nameplate rating per set, no reader outside the deal knows whether this is several hundred large sets or several thousand small ones, and those two answers imply different factories.
The last gap is downstream of Generac entirely. Standby engines at this volume need air permits from state and county regulators who have started pushing back on data center generator fleets. Generac sells the hardware. Amazon carries the permitting risk, and neither party has said where these sets will actually sit.
