Why is Generac stock surging today?
Generac's stock surged 27.3% after-hours after announcing a long-term supply deal with Amazon for backup power generators. The deal includes a warrant for Amazon to acquire up to 1.69 million Generac shares, contingent on $8 billion in purchases. Generac's data center backlog is now $1.6 billion. The move was driven by company-specific news, not broader market trends.
