Eaton makes equipment that controls and distributes electricity. It sells circuit breakers, switchgear, power backup systems, aerospace hydraulics, and vehicle drivetrain parts to customers in 180 countries. Money comes in when factories, data centers, hospitals, airlines, and truck makers order Eaton's products. Because most of those customers are running big capital projects, Eaton's revenue rises and falls with the broader economy. But lately, a wave of spending on data centers and electrical grid upgrades has been pushing demand higher across Eaton's biggest businesses. The diagram below traces where the money goes.

Five years of numbers tell a clear story. Revenue has climbed every single year, from $19.6 billion in 2021 to $27.4 billion in 2025. That is not just inflation. Gross margin, which is the share of each dollar of revenue left after paying for materials and production, has risen from about 32 cents on the dollar to about 38 cents. That means Eaton is not just selling more. It is keeping more of what it sells.
Eaton Revenue 2021 to 2025 (USD billions)
Revenue has grown every year for five consecutive years, reaching $27.4 billion in 2025.
Cash generation has followed the same path. Free cash flow, which is the cash left over after the company pays for its buildings and equipment, more than doubled from $1.6 billion in 2021 to $3.6 billion in 2025. That extra cash is what funds acquisitions, pays down debt, and returns money to shareholders. Net debt, the amount owed minus cash on hand, has stayed in a range between $6.5 billion and $8.4 billion across the five years. It rose when Eaton made big purchases and stayed roughly flat otherwise.
$3.6B
Free cash flow in 2025, up from $1.6B in 2021
The gross margin did dip slightly in 2025, falling from about 38.2% in 2024 to about 37.6%. That small pullback is worth watching. Eaton's own filings warn that inflation in raw materials and labor is an ongoing pressure. The company has been raising prices to offset those costs, but it acknowledges that pushing prices too high can push customers toward cheaper competitors.
Margins expanded significantly over four years before dipping slightly in 2025.

Eaton bets bigger on data centers and aerospace
In 2025, Eaton acquired Fibrebond, which makes modular buildings for large data centers, and Resilient Power Systems, which makes solid-state transformer technology used in data centers and energy storage. It also announced plans to acquire Boyd Thermal, which handles liquid cooling for data center chips. Then in January 2026, it closed the purchase of Ultra PCS to expand its aerospace electronics capabilities. At the same time, Eaton announced it plans to spin off its Mobility business, which makes vehicle and electric vehicle parts, into a separate public company by the end of the first quarter of 2027. Taken together, these moves signal that Eaton is doubling down on electrical infrastructure and stepping back from vehicle parts.
That strategic shift matters because it changes what kind of company Eaton will be. The Mobility business today serves truck and car makers. Spinning it off means Eaton's remaining revenue will lean even more heavily on electrical systems, data centers, and aerospace. The question is whether the spin-off goes smoothly.
What is a spin-off?
A spin-off is when a company separates one of its businesses into a brand new, independent company that trades on its own. Shareholders of the original company usually receive shares in the new company. Spin-offs can unlock value but they also cost money to execute and can distract management from running the rest of the business.
Eaton's own risk filings flag the Mobility spin-off as a high-severity risk. If it is delayed, fails to complete, or costs more than expected, the company could lose the financial benefits it is counting on and leadership attention could be pulled away from day-to-day operations. That is a real operational risk sitting directly on top of the company's biggest strategic move.
Other documented risks include Eaton's reliance on single-source suppliers. For some materials and parts, there is simply no backup supplier available. A weather event, a conflict, or sanctions in the wrong place could halt production of Eaton's most profitable products. The company also faces data protection rules in many countries. A violation of the European Union's privacy law, known as GDPR (General Data Protection Regulation), could cost up to 4% of total global revenue, which at $27.4 billion in annual sales would be a very large fine. Finally, Eaton is building artificial intelligence tools into its products and operations. That creates new risks around confidentiality, errors, and regulations that are still being written in different countries.

Why cyclical matters here
A cyclical business is one where sales go up when the economy is growing and fall when it slows down. Eaton sells to factories, construction projects, and airlines, all of which cut spending during recessions. The current revenue growth story is partly Eaton-specific and partly a reflection of a strong spending environment for electrical infrastructure. Those two things are easy to confuse.
The data center and grid upgrade wave has been a powerful tailwind. In 2025, Eaton's electrical businesses reported that 22% of those segments' sales went to just six large customers. That concentration means a shift in spending by a small number of buyers could move Eaton's numbers meaningfully. The aerospace segment has the same dynamic: 20% of its 2025 sales went to just three aircraft manufacturers.
In the Vehicle segment, a single set of four large vehicle manufacturers accounted for 37% of 2025 sales. Once the Mobility spin-off happens, that concentrated customer exposure leaves Eaton's books entirely.
The Bet
Eaton's electrical business keeps growing because the global buildout of data centers, power grids, and electrified infrastructure is a decade-long cycle, not a short-term bump. If that spending cycle continues at its current pace, Eaton's newly focused electrical and aerospace business will generate the revenue and margins needed to justify its strategic shift. If the data center construction wave slows sooner than expected, or if a broader economic slowdown causes industrial customers to freeze capital spending, Eaton's revenue growth stalls at exactly the moment it has restructured itself around that growth continuing.
Open question
Eaton is reshaping itself into a more focused electrical infrastructure company. Margins have expanded, free cash flow has more than doubled in five years, and the acquisition pipeline is aimed squarely at data centers and aerospace. But the Mobility spin-off is not done yet, the company leans on a small number of very large customers, and its revenue is tied to an economic cycle that will eventually turn. Is the data center and grid spending wave durable enough to carry Eaton through its restructuring, or is the company making its biggest strategic bet at the peak of the cycle?
