Generac Holdings shares jumped more than 40 percent in after-hours trading Wednesday after the company disclosed a long-term agreement to supply backup generators to Amazon's data-centre operations, a deal that could eventually reach $8 billion in equipment sales.
The contract details
Initial deliveries are slated for 2027 and 2028 and carry an expected value of roughly $2.4 billion. The full agreement contemplates generator purchases of up to $8 billion, a figure that would dwarf Generac's existing data-centre backlog of $1.6 billion reported in prior filings.
Warrant structure
As part of the arrangement, Generac issued a warrant to an Amazon subsidiary covering 1.69 million shares at an exercise price of $200.9266 each. Just over 307,000 of those shares vested immediately; the remainder unlock only as Amazon places additional generator orders, tying the equity incentive directly to procurement volume.
Why the market moved
The rally reflects more than a single customer win. Data-centre operators are scrambling for reliable backup power as cloud and AI workloads push electricity demand beyond what ageing grids can guarantee. Generac has spent years repositioning its commercial and industrial division toward that demand, and the Amazon pact validates the thesis at a scale few anticipated.
What to watch
Investors will now track how quickly the $2.4 billion in scheduled deliveries converts into recognized revenue, whether Amazon exercises the remaining warrant tranches, and whether other hyperscalers follow with similar long-term supply commitments. The backlog provides visibility, but execution on multi-year industrial contracts rarely proceeds in a straight line.
