Flex is splitting around AI power
- Flex plans to spin off its Cloud and Power Infrastructure business in early calendar 2027.
- CPI is the growth engine, with FY 2026 revenue up 38% and Q4 fiscal 2026 revenue of $1.8 billion.
- The remaining company should be more focused on healthcare, industrial, communications, and cash flow.
- The bear case is simple: the spin could slip, cost more than expected, or miss the AI spending cycle.
- The stock already gets some credit for the plan, so valuation is not a clean bargain.
Two companies, one big test
Flex is no longer just a contract manufacturer story. The company plans to split into two public companies. One will be Cloud and Power Infrastructure, or CPI. The other will hold the RMS and ITS manufacturing businesses.
The bull case is that CPI gets valued like an AI infrastructure company after the spin. CPI grew FY 2026 revenue by 38%. In Q4 fiscal 2026, it produced $1.8 billion of revenue and a 9.9% adjusted operating margin. That is a very different profile from a broad manufacturing company.
The remaining Flex could still be valuable. It should be cleaner, steadier, and more focused on margins and cash flow. It will make complex products for areas like healthcare, industrial automation, networking, and communications.
The hard part is execution. A spin-off can create value, but it can also distract managers, add costs, and expose both new companies to problems that were easier to absorb together. The current score fits that mixed setup: strong operating performance, but only middling sentiment, valuation, and financial health.
Manufacturing plus AI infrastructure
Flex makes money by helping large customers design, source, build, and deliver complex products. That can mean medical devices, robotics systems, networking gear, or cloud infrastructure. Customers use Flex when building the product themselves would be too slow, costly, or hard to scale.
CPI is different from the older manufacturing mix. It sells integrated power, cooling, and compute systems for AI data centers and utility infrastructure. Large cloud companies need those systems because AI servers use a lot of power and heat up fast.
RemainCo will be the manufacturing and supply chain business after CPI leaves. Its job will be to improve margins, generate cash, and return capital while growing at a slower pace.
The model breaks if AI data center demand cools, if large customers cut orders, or if the separation makes the cost structure worse instead of better.
What Flex builds
Data center solutions
CPI provides compute, cooling, and power systems for AI data centers. This is the main reason investors are paying closer attention to Flex.
Power and utility infrastructure
Flex builds systems tied to power delivery and grid modernization. This sits with CPI and needs heavy capital spending to meet demand.
Health solutions
Flex makes medical devices and healthcare equipment. This work tends to be complex and regulated, which can support better margins.
Industrial and robotics
The company serves warehouse automation, robotics, automotive, and semiconductor equipment customers. These markets can grow, but they are tied to industrial spending cycles.
Networking and communications
Flex builds high-performance networking and satellite communications products. This will be part of RemainCo after the planned split.
Lifestyle and consumer devices
Consumer-related work is a softer part of the portfolio. Management has been de-emphasizing lower-value markets in this area.
The split in the numbers
Mix uses Q4 fiscal 2026 segment revenue disclosed on the Q4 fiscal 2026 call: CPI $1.8 billion, RMS $2.7 billion, and ITS $2.9 billion. CPI has customer concentration with Google and other large cloud buyers.
What could go wrong
Spin-off delay or disruption
High impact · Medium oddsFlex says the CPI spin is expected in the first quarter of calendar 2027. The FY 2026 10-K warns that the separation may not be completed on the planned terms or timeline, or at all. A delay would weaken the value unlock case.
CPI customer concentration
High impact · Medium oddsCPI growth depends on large contracts with Google and other hyperscalers, which are the biggest cloud companies. If one large buyer slows orders, pushes out builds, or changes suppliers, the growth curve could bend fast.
Heavy capital spending misses its return
High impact · Medium oddsCPI needs a large buildout to chase demand. The internal thesis cites planned FY 2027 CapEx of $1.4 billion to $1.6 billion and CPI revenue growth guidance of 65% to 75%. If demand falls short, returns on that spending could disappoint.
AI infrastructure cycle peaks
High impact · Medium oddsThe bull case assumes AI data center spending stays strong for several years. If cloud companies pause builds after a large wave of spending, CPI could be left with too much capacity. That would hurt both growth and margins.
RemainCo gets labeled low growth
Medium impact · Medium oddsAfter CPI leaves, RemainCo may look like a slower industrial and healthcare manufacturer. It can still create value through margins and cash flow, but investors may pay a lower multiple if growth is only low-to-mid-single digit.
In one breath
What does Flex actually do?
Flex helps companies build complex physical products at scale. Its work ranges from medical devices and robotics to networking gear and AI data center power, cooling, and compute systems.
Why is Flex spinning off CPI?
CPI is growing much faster than the rest of Flex because it serves AI data centers and power infrastructure. As a separate company, it may get a higher valuation than it gets inside a broad manufacturer.
Is Flex mainly an AI stock now?
Not fully. CPI is the main growth story, but RMS and ITS are still large parts of the company. After the spin, investors will own two different stories unless they sell one side.
What is the biggest thing to watch next?
The Form 10 registration statement for the spin-off is the key next document. It should show standalone margins, debt, cash flow, and capital needs for CPI and RemainCo.
