Generac (GNRC) stock jumped 35% in premarket trading Thursday after the company disclosed a long-term supply agreement with Amazon for backup generators destined for data centers. The stock was trading around $235 in premarket, which would put it roughly 72% above its 2025 closing price of $136.37.
The deal covers initial generator deliveries valued at $2.4 billion, spread across 2027 and 2028. That averages out to about $1.2 billion per year, a large number relative to Generac’s total 2025 revenue of $4.2 billion.
The agreement was disclosed in a Securities and Exchange Commission filing Wednesday evening. It identifies the customer as Amazon Data Services, the same “second hyperscale customer” Generac had referenced back in July without naming.
As part of the deal structure, Amazon receives an equity warrant allowing it to buy up to 1.69 million GNRC shares at roughly $201 each. That represents about 2.6% of fully diluted shares.
Around 308,000 of those shares vested immediately upon signing. The rest vest incrementally as Amazon and its affiliates hit cumulative spending milestones on Generac generators, up to a total of $8 billion. Full vesting runs through 2033.
Data Center Business Gaining Ground
Generac’s data center exposure has been building for some time. In its second quarter 2026 report, commercial and industrial sales rose 29%, and the company’s data center backlog had already hit around $1.6 billion before this deal was even disclosed.
The Amazon agreement is global and covers data centers outside the United States as well.
On the earnings front, Generac beat profit estimates in Q2, posting adjusted earnings of $2.91 per share against an estimate of $2.00. Revenue came in at $1.17 billion, slightly below the $1.18 billion forecast. A tariff refund contributed to the earnings beat.
Analyst Reaction
Barclays kept its Equalweight rating on GNRC after the announcement, holding its price target at $278.
Cantor Fitzgerald was more upbeat, raising its price target to $333 and pointing to strength in the data center segment as the reason.
Needham reiterated its Buy rating with a $282 target. The firm highlighted the tariff refund as a factor in the strong Q2 results.
GNRC closed 2025 at $136.37 and had gained about 28% through Wednesday’s regular session before the after-hours news hit. The stock had previously reached a 52-week high of $296.44 on June 25 before falling around 41% through Tuesday.
