Generac Shares Jump After Amazon Warrant Deal Tied to $2.4 Billion Data-Center Power Agreement

Generac Holdings shares jumped more than 40% in extended trading on Wednesday after a regulatory filing disclosed that Amazon had received warrants to purchase up to 1.69 million shares of the backup-power maker, tied to a supply agreement that could bring Generac $2.4 billion in initial deliveries over 2027 and 2028, according to CNBC and Seeking Alpha.

What the filing describes

Per the filing cited by CNBC, Generac will supply Amazon with backup power generators for its data centers, with initial deliveries expected to total $2.4 billion across 2027 and 2028. In exchange, Amazon was granted warrants to purchase up to $340 million worth of Generac stock, structured as the right to acquire up to 1.69 million shares if certain business volume milestones are met, Seeking Alpha reported.

CNBC reported that about 308,000 warrant shares vested immediately, with the remaining tranches vesting contingent on payments Amazon makes for the generators. That implies roughly 1.38 million warrant shares remain tied to future milestones, calculated by subtracting the 308,000 immediately vested shares reported by CNBC from the 1.69 million total shares reported by Seeking Alpha (1,690,000 − 308,000 = 1,382,000).

Neither source detailed the warrants' strike price or expiration date, and the filing as described does not indicate whether the $2.4 billion supply arrangement is exclusive to Amazon or whether it includes options for additional volumes beyond 2028. Those specifics were not part of the reporting reviewed.

Dilution in context

CNBC reported that the warrants are equivalent to almost 3% of Generac's outstanding shares, and that the company's market capitalization stood at about $10.3 billion as of Wednesday's close. Neither outlet compared the $2.4 billion in initial deliveries against Generac's annual revenue or existing order backlog, and no updated guidance or capacity-expansion plans from Generac were referenced in the reporting.

Part of a broader Amazon playbook

The Generac arrangement follows a similar structure Amazon used just days earlier with Qualcomm. CNBC reported that Amazon struck a deal to use Qualcomm's custom artificial intelligence chips and, in return, received warrants to acquire as much as $4 billion in Qualcomm stock. CNBC also noted that Amazon frequently purchases warrants and takes stakes in its suppliers, pointing to prior arrangements with semiconductor firm Astera Labs, air cargo contractor ATSG, green hydrogen supplier Plug Power, and grocery distributor SpartanNash.

These supplier-warrant deals are occurring alongside a broader expansion of Amazon Web Services' data-center footprint tied to surging AI compute demand. CNBC reported that AWS signed a $38 billion cloud deal with OpenAI last November and opened an $11 billion campus for Anthropic last October. Read together, the Generac warrant deal appears to fit a pattern in which Amazon secures both supply commitments and equity upside from vendors supporting its AI infrastructure buildout, though the reporting reviewed did not draw that connection explicitly beyond listing the individual transactions.

Market reaction

The stock reaction was immediate and pronounced. CNBC reported that Generac shares soared more than 40% in extended trading on Wednesday following the disclosure, and Seeking Alpha headlined the move as Generac "surging" on the $2.4 billion Amazon deal. Neither source reported how other backup-power or generator manufacturers traded after the announcement, and no claims about competitor share-price moves or market-share shifts appear in the material reviewed.

Bottom Line

The disclosure marks a concrete, filing-based supply and warrant arrangement between Amazon and Generac, with initial deliveries of backup generators for Amazon's data centers expected to total $2.4 billion across 2027 and 2028, and warrants covering up to 1.69 million Generac shares, roughly 3% of shares outstanding, tied to business volume milestones. Key structural details, including the warrants' strike price, expiration, and whether the supply relationship is exclusive, were not specified in the reporting available. The stock's sharp extended-trading gain reflects investor reaction to the disclosed deal size relative to Generac's market capitalization, though the reporting reviewed did not include comparisons to Generac's revenue base, backlog, or updated financial guidance.
