Generac Reports Record Quarterly Revenue as Data Center Demand Drives Strong Earnings Growth
October 28, 2026 — Generac Holdings Inc. (NYSE: GNRC) reported record third-quarter revenue on Wednesday, October 28, as accelerating demand for backup power systems used in data centers helped offset ongoing challenges in parts of the energy equipment market.
The Wisconsin-based manufacturer generated $1.29 billion in quarterly sales, representing approximately 16% growth from the same period last year. Although revenue fell short of Wall Street expectations, stronger profitability and expanding commercial demand highlighted the company's growing importance in the infrastructure supporting artificial intelligence and cloud computing.
Generac also reported a substantial increase in its backlog of data center orders, providing greater visibility into potential revenue growth over the coming years.
Quarterly Revenue Reaches an All Time High
Generac reported third-quarter net sales of approximately $1.29 billion, compared with $1.11 billion during the corresponding quarter of 2025.
The 16% increase reflected strong demand across the company's commercial and industrial operations, along with improving residential generator sales.
Despite the record performance, revenue came in below analysts' consensus estimate of approximately $1.32 billion to $1.33 billion.
However, the company's earnings performance exceeded market expectations.
Adjusted earnings reached $2.54 per diluted share, surpassing the approximately $2.43 analysts had anticipated. This represented a significant improvement from adjusted earnings of $1.83 per share in the prior-year quarter.
On a generally accepted accounting principles basis, net income attributable to Generac increased to approximately $109 million, compared with $66 million a year earlier.
GAAP diluted earnings rose to $1.83 per share from $1.12 per share.
The results suggest that Generac is benefiting not only from higher sales volumes but also from improvements in operating efficiency and profitability.
Data Center Demand Becomes a Major Growth Engine
One of the most significant developments in Generac's quarterly report was the continued expansion of its commercial and industrial business.
External sales in this segment increased approximately 28% to $552 million, compared with $432 million during the same period last year.
The growth was supported by increasing demand for backup power systems used in data centers, where reliable electricity supplies are essential for maintaining uninterrupted computing operations.
Artificial intelligence infrastructure has become an increasingly important source of demand for power generation equipment.
Large data centers require substantial electrical capacity, and operators must protect their facilities against unexpected utility interruptions.
Backup generators provide an important layer of protection, helping maintain operations when primary electrical supplies become unavailable.
Generac's expanding participation in this market positions the company to benefit from continued investment in cloud computing, artificial intelligence, and digital infrastructure.
Major Amazon Agreement Strengthens Long Term Outlook
Generac's growing presence in the data center industry received a significant boost from a previously announced agreement with Amazon.
The agreement includes a long-term arrangement to supply backup power generators for Amazon's data center operations.
Initial deliveries under the agreement are expected to total approximately $2.4 billion during 2027 and 2028.
The arrangement represents a substantial commercial opportunity and reinforces Generac's position as a supplier of critical infrastructure equipment to major technology companies.
Importantly, the Amazon agreement is not the company's only source of expanding data center demand.
Generac reported that additional commitments from both new and existing customers have increased its backlog of products destined for the data center market to approximately $4.5 billion.
This backlog provides meaningful visibility into future business activity, although actual revenue recognition will depend on production schedules, deliveries, customer requirements, and successful execution.
Management is continuing to expand manufacturing capacity to accommodate the expected increase in demand.
Residential Generator Business Returns to Growth
While data center demand attracted considerable attention, Generac also reported encouraging results in its residential business.
Residential segment external sales increased approximately 9% to $743 million, compared with $682 million in the prior-year quarter.
The improvement reflects renewed demand for home standby generators and portable power equipment.
Generac attributed the growth partly to increasing concerns about electricity reliability.
Extreme weather events, aging electrical infrastructure, and rising electricity consumption have contributed to greater consumer interest in backup power solutions.
Homeowners seeking protection against extended outages may invest in permanently installed standby generators or portable systems capable of supplying electricity during emergencies.
Although residential demand can fluctuate with weather conditions, consumer spending, and housing market activity, the latest results indicate that this business is contributing positively to the company's overall performance.
Profit Margins Improve as Revenue Expands
Generac's profitability improved considerably during the quarter.
Gross profit margin increased to 39.9%, compared with 38.3% during the third quarter of 2025.
The improvement was supported by favorable relationships between selling prices and production costs, including reduced tariff-related expenses.
These benefits were partially offset by changes in the company's sales mix.
Adjusted earnings before interest, taxes, depreciation, and amortization reached approximately $256 million, compared with $193 million a year earlier.
The corresponding adjusted EBITDA margin increased to 19.8% from 17.3%.
This expansion indicates that Generac converted a larger portion of its revenue into operating profitability despite increased spending on future growth initiatives.
Operating expenses rose approximately $31.6 million, or 10%, compared with the previous year.
Much of the increase reflected investments supporting commercial and industrial expansion, higher marketing expenditures, and additional employee compensation costs.
These investments could support future revenue growth, although their ultimate returns will depend on the company's ability to fulfill its expanding order backlog efficiently.
Cash Flow Strengthens Financial Position
Generac also reported improved cash generation during the quarter.
Operating cash flow increased to approximately $171 million, compared with $118 million during the same period in 2025.
Free cash flow rose to approximately $132 million from $96 million.
The improvement was primarily driven by stronger operating earnings, partially offset by higher capital expenditures.
Cash generation is particularly important as Generac invests in additional manufacturing capacity to meet demand from data center customers.
Expanding production facilities, equipment, and supporting infrastructure can require substantial upfront spending before the associated revenue is realized.
Strong operating cash flow gives the company greater flexibility to finance these investments while maintaining financial stability.
Investors will nevertheless be monitoring whether capital spending increases as the company prepares for the substantial deliveries expected in 2027 and 2028.
Management Maintains Revenue Growth Forecast
Following the third-quarter results, Generac maintained its full-year 2026 revenue growth outlook.
The company continues to anticipate net sales growth in the mid-to-high teens percentage range compared with 2025.
Management also maintained its expectation for a full-year net income margin of approximately 9% to 10%.
However, the company improved the lower end of its adjusted EBITDA margin forecast.
Generac now expects a full-year adjusted EBITDA margin of approximately 20.5% to 21%, compared with its previous forecast of 20% to 21%.
The adjustment reflects increased confidence in the company's profitability as commercial demand strengthens and operating efficiencies improve.
Maintaining the revenue outlook while raising the lower end of margin expectations suggests management sees opportunities to generate stronger earnings from its existing business.
Artificial Intelligence Infrastructure Creates New Opportunities
The rapid development of artificial intelligence is reshaping demand across multiple industrial sectors, including electrical equipment, cooling systems, power generation, and data center construction.
Generac's expanding data center business illustrates how companies outside the traditional semiconductor and software industries can benefit from rising investment in computing infrastructure.
Unlike businesses that develop AI applications directly, Generac supplies equipment that helps support the physical infrastructure required to operate them.
As technology companies construct larger computing facilities, reliable backup power becomes increasingly important.
However, the company's growth opportunity is accompanied by execution risks.
Large customer agreements require careful production planning, dependable supply chains, and sufficient manufacturing capacity.
Project delays, changes in customer spending, or unexpected production costs could affect the timing and profitability of future deliveries.
Generac must also balance investment in its rapidly expanding commercial operations with continued development of its established residential and energy technology businesses.
What Investors Should Watch Next
Several developments could influence Generac's financial performance over the coming quarters.
The most important may be the company's ability to convert its approximately $4.5 billion data center backlog into revenue while maintaining attractive operating margins.
Investors will also be watching the pace of manufacturing expansion, the timing of major customer deliveries, and the financial impact of additional capital expenditures.
Residential generator demand remains another important consideration, particularly as electricity reliability concerns and severe weather events influence consumer purchasing decisions.
Meanwhile, competitive conditions, raw material costs, tariffs, and broader economic trends could affect profitability.
Although third-quarter revenue fell short of analyst expectations, the combination of record sales, stronger earnings, improved cash flow, and a rapidly expanding commercial backlog provides several encouraging indicators.
A New Chapter for the Power Equipment Manufacturer
Generac's third-quarter performance highlights an important transformation in the company's growth profile.
Long recognized for residential backup generators, the manufacturer is becoming an increasingly significant participant in the infrastructure supporting large-scale data centers.
The company's $2.4 billion Amazon supply agreement and approximately $4.5 billion data center backlog demonstrate the scale of the opportunity.
At the same time, improving residential sales and stronger profit margins suggest that growth is not limited to a single customer or business segment.
For shareholders, the central question is whether Generac can successfully execute its manufacturing expansion plans and convert these opportunities into sustainable earnings and cash flow.
With record quarterly revenue of $1.29 billion, adjusted earnings of $2.54 per share, and an improved profitability outlook, Generac enters the final months of 2026 with considerable momentum.
The company's ability to capitalize on accelerating investment in artificial intelligence infrastructure could play an increasingly important role in determining its financial performance over the next several years.
