Key points

  • Amazon (AMZN) warrant on up to 1,693,745 Generac (GNRC) shares
  • Exercise price $200.9266, above Wednesday's $175.11 close
  • Warrant vested immediately for 307,954 shares
  • Full warrant vesting tied to $8 billion in qualifying payments

Generac Holdings (GNRC) has agreed to supply backup generators for Amazon data centers. As part of the deal, Amazon (AMZN) received the right to buy up to 1,693,745 Generac shares at $200.9266 each, according to an 8-K filed Wednesday.

Generac shares rose to $232.98 shortly before 8 p.m. Eastern, about 33% above their regular-session closing price of $175.11.

The warrant is the unusual part

A warrant is a right to buy stock at a set price later, not the stock itself. This one went to Amazon.com NV Investment Holdings, a wholly owned Amazon subsidiary. At its maximum it covers 2.9% of Generac's 59 million shares outstanding.

The warrant vested immediately for 307,954 shares. The remaining portion vests as qualifying payments reach specified thresholds. The filing ties that vesting to "aggregate gross payments, net of certain offsets, received by the Company and its global affiliates from or on behalf of Amazon and its affiliates for backup power generators for Amazon data centers, up to a total of $8 billion."

Amazon's agreed purchase price was about 15% above Wednesday's closing price. Within hours of the filing, Generac shares had risen above that level.

Amazon has until September 16, 2033 to buy the shares it has earned the right to buy, and it can do that all at once or in pieces. It can pay cash, or take fewer shares instead of paying. The agreement allows adjustments to the purchase price and share count for certain corporate actions, and Generac agreed to register the shares so Amazon can sell them.

$2.4 billion of expected deliveries, an $8 billion threshold

Generac and Amazon signed the supply agreement the same day. The filing says initial deliveries of backup generators are expected to total $2.4 billion in 2027 and 2028.

That $2.4 billion is the near-term number. The $8 billion is the ceiling on the vesting schedule, not a committed order book, and the filing does not say what happens if the orders fall short.

Amazon links supplier purchases to an equity incentive

The shape here is familiar. An AI buyer receives the right to acquire equity in a supplier at the same time it commits to buy from it, which is the structure running through the circular AI trade we mapped earlier this month.

What is different is which end of the supply chain it reaches. The equity-linked deals so far have clustered around chips, clouds and model developers. This one is for diesel and gas backup generators, the machines that keep a data center running when the grid does not.

Generac issued the warrant privately and disclosed it in the 8-K as an unregistered sale of securities.

Frequently asked questions

What did Generac give Amazon?

A warrant. Generac (GNRC) issued Amazon.com NV Investment Holdings, a wholly owned Amazon (AMZN) subsidiary, the right to buy up to 1,693,745 Generac shares at $200.9266 each. Those shares equal about 2.9% of Generac's 59 million shares outstanding. Amazon can exercise in cash or cashless, in whole or in part, at any time up to September 16, 2033, and the terms carry anti-dilution adjustments and registration rights.

Does Amazon own 2.9% of Generac now?

No. A warrant is a right to buy rather than ownership, and it vested immediately for only 307,954 shares. The rest becomes exercisable in tranches tied to aggregate gross payments, net of certain offsets, that Generac and its global affiliates receive from Amazon for backup power generators for Amazon data centers, up to a total of $8 billion.

How big is the supply agreement?

Generac and Amazon signed a long-term supply agreement for backup generators on the same day as the warrant. The 8-K says initial deliveries are expected to total $2.4 billion in 2027 and 2028. The $8 billion figure is the ceiling on the warrant's vesting schedule rather than a committed order book, and the filing does not say what happens if orders fall short.

Why did Generac shares jump?

The move followed the disclosure. Generac closed the regular session on September 16, 2026 at $175.11 and traded at $232.98 after hours shortly before 8pm ET, up about 33%. The warrant's $200.9266 exercise price was set roughly 15% above that closing price, so it was struck at a premium to the market before the after-hours move carried the stock through it. This is general information, not investment advice.
