AI VERDICT

JUSTIFIEDCONFIDENCE5/5

Generac shares rose 32.6% after announcing an Amazon supply agreement tied to up to $8 billion in data-center generator payments, including $2.4 billion of expected initial deliveries in 2027 and 2028. The Amazon warrant for up to 1.69 million shares creates dilution risk, but the scale and strategic significance of the contracted demand support the sharp move.

WHYA 32.6% pre-market jump is large, but is supported by a multibillion-dollar Amazon supply commitment and expected $2.4 billion initial deliveries; the warrant adds issuance risk rather than negating the catalyst.
