Summary
Generac Holdings shares soared in after-hours trading following a major supply agreement with Amazon, while Fluence Energy and Lennar Corp. both fell on disappointing financial updates.
Generac Holdings (NYSE: GNRC) shares surged in extended trading after the company announced a multi-billion dollar supply agreement with Amazon, while Fluence Energy (NASDAQ: FLNC) and homebuilder Lennar Corp. (NYSE: LEN) both saw their stocks fall on disappointing financial news.
Generac Soars on AWS Partnership
Generac's stock jumped 30% in after-hours activity following the announcement of a major long-term agreement to supply backup power generators for Amazon Web Services (AWS) data centers. The contract carries a potential total value of up to $8 billion.
The company stated that initial deliveries valued at $2.4 billion are scheduled for 2027 and 2028. As part of the multi-year deal, Generac granted Amazon a warrant to purchase up to approximately 1.69 million of its shares at an exercise price of $200.9266 per share, tied to payment milestones through 2033. For investors, this agreement signals a significant and stable long-term revenue stream for the power equipment manufacturer.
Fluence Slashes Outlook on Supply Chain Woes
In contrast, shares of Fluence Energy plummeted 18% after the company sharply reduced its financial outlook for the 2026 fiscal year. The energy storage firm cited ongoing supply chain bottlenecks that are impacting its U.S. battery production.
AdFluence provided the following revised guidance:
- Full-year revenue is now expected to be approximately $2.4 billion, down from a previous midpoint target of $3.0 billion.
- The company projects a wider adjusted EBITDA loss of around $200 million, a stark revision from its prior guidance of a $10 million loss.
Lennar Misses Estimates, Guides Cautiously
Homebuilder Lennar Corp. saw its shares decline 2% after its third-quarter results missed Wall Street expectations on both the top and bottom lines. The company reported Q3 earnings per share of $1.19 on revenue of $8.05 billion, falling short of the consensus estimates for $1.29 in EPS and $8.31 billion in revenue.
Lennar's guidance for the fourth quarter suggested continued pressure on its business from the macroeconomic environment. The company forecast home sales gross margins between 15.5% and 16.0%, indicating that higher mortgage rates and the use of buyer incentives are weighing on profitability.
