Generac Stock Surges on $2.4B Amazon Deal as AI Power Thesis Reprices GNRC

TradingKey - Generac closed at $175.11 on September 16. That price is out of date for September 17 setups. On September 16 after the market closed Generac announced a long-term agreement to provide backup generators to Amazon’s data centers. Generac expects delivery of approximately $2.4 billion of generators to Amazon over the years 2027 and 2028. As of the time of this writing, Generac is trading at about 234-235 in extended/premarket indications, roughly 34% above the regular-session close. Before this announcement, the downside target on Generac was about $167.56. That old bearish $167.56 target is no longer the primary setup after the Amazon announcement and large gap higher.

Amazon Deal Is a Step-Change for the Data-Center Story

Compared to Generac’s previous expectations on data center business, expected 2026 data center business was approximately $450 million. Generac expects approximately $2.4 billion of initial Amazon generator deliveries in the years 2027 and 2028.

Amazon has the right to purchase up to 1,693,745 shares of Generac at $200.9266 per share. Of the 1,693,745 warrant shares, 307,954 vested immediately. The remaining 1,385,791 shares vest in multiple tranches based on aggregate generator payments received from Amazon and its affiliates. Full vesting is tied to aggregate gross payments, net of certain offsets, of up to $8 billion for backup generators. The $8 billion figure is therefore a generator-purchase milestone for warrant vesting, not an amount created by Amazon exercising the warrant.

In the near term, Generac should focus on the initial expected business of approximately $2.4 billion from Amazon and not from the speculative expected business of approximately $8 billion.

Data-Center Backlog Was Already Accelerating

Prior to the recent announcement from Amazon, Generac was already disclosing a rapidly increasing data-center backlog. In just 90 days, Generac amassed approximately $1 billion in data-center orders, bringing the total backlog to approximately $1.6 billion. Management also noted in the recent call that they have secured two hyperscale contracts and the $1.6 billion backlog did not include committed volumes from the second hyperscale agreement. The company expects more than $1.25 billion of global large-megawatt manufacturing capacity by Q4 2026 and a path to roughly triple that capacity by the end of Q3 2027.

The recent announcement from Amazon changed the situation for Generac. Generac no longer needs to validate that hyperscale data centers are evaluating their products. The question is whether they can manufacture and deliver large data-center products at an profits at an acceptable level.

C&I Is Becoming the Main Growth Engine

During the second quarter, the C&I (Commercial & Industrial) segment of Generac’s business increased by 29% compared to the same period the prior year. The Residential segment decreased by 2% compared to the same period last year. If the Data-Center segment continues to increase as expected, it could surpass the Residential segment in the foreseeable future.

The Q2 margins for Generac were 24.8% primarily due to a $71 million credit for tariff refunds. Excluding that credit, the adjusted EBITDA margin would have been about 18.8% for the quarter. Generac has said vertical integration and expanded large-megawatt production should improve the C&I margin profile as data-center volumes scale. The recently closed acquisition of Enercon and the recently announced expansion of Generac’s large-megawatt manufacturing will allow Generac to meet increasing customer demands.

Amazon Deal Also Creates New Risks

While the agreement improves Amazon’s visibility, it also increases the risk of Amazon concentrating a material portion of Generac’s C&I business, and the risk Generac takes on executing quickly to ensure capacity and flexibility in its production, supply chain, and workforce to support growth across numerous product lines.

Approximately 2.9% dilution of Generac’s shares is possible if the full warrant ultimately vests and is exercised. Although this dilution is noteworthy, it is possible commercial use of Generac’s products would increase in conjunction with warrant vesting.

The residential market is where demand for Generac’s products is less. The hurricane season has so far been quiet and therefore not as likely to increase demand for Generac’s products. However, Generac has made strategic business adjustments to diversify and position itself to gain from the growing demand for data center and artificial intelligence (AI) infrastructure.

Generac Technical Analysis: Amazon Gap Invalidates the Old Bearish Setup

GNRC closed at $175.11 on September 16, with the supplied chart showing the price at $175.07 and the stock having violated its $178.33 support and en route to the $167.56 level. This bearish view was in harmony with the rest of the tech picture, prior to the Amazon announcement.

Bear in mind the picture has changed dramatically after the release. The stock was indicated in the 234-235 area in extended/premarket trading. As a result, the bearish picture has changed rather dramatically. The previous resistance at 205.71-209.54 has been cleared in the indicated post-news move and should now be watched as part of the gap-support region, while the old $167.56 downside target is no longer the relevant primary support level.

There are a couple of things to look for on the open. First, I would look for the stock to hold the $200-205 area. If so, this would make the $234-235 area the next major upside target, and in the process, revalidate the new bullish picture.

If the stock opens below $200, the new picture would quickly change back to bearish, and $192.21 and the $178.33 area would quickly come into play. The RSI of 36, prior to the announcement, describes the pre-announcement chart only and should not be used to judge post-gap momentum.

Why is Generac stock in focus now?

Generac announced a multi-year contract with Amazon to provide backup power to Amazon data centers, with expected revenue of $2.4 billion for 2027 and 2028. This contract award from Amazon validates and endorses Generac’s multi-year strategic initiative to transform its core business away from the residential generator business that was historically impacted by hurricane cycles.

What level matters most after the Amazon gap?

The first important post-gap support level is the 200-205 area. If this support holds, the overall trend will be up. A close below $200 increases the risk of a deeper decline to the $192.21 and $178.33 support levels.

Bottom Line

Generac’s current structure is bullish as it has transformed and upgraded its long-term outlook after the Amazon announcement. The biggest concerns are competitive, customer concentration, and margin and return on investment (ROI) targets. The old bearish $167.56 target is invalid, and the new structure will most likely be in the $234 - $235 range with the $296.44 level as the major top.
