Flex Ltd. (FLEX)

Investment Review After Q4 FY2026 Earnings (stock price as of 2026.07.10)

TL;DR

Flex is one of the world's largest contract manufacturers — building electronics for other companies across autos, healthcare, and increasingly AI data centers (power and liquid cooling). Just reported: Q4 FY2026 revenue up 17% to $7.5B, record margins, and adjusted EPS up 27% — plus the big news: a plan to spin off its fast-growing data-center power business as a separate public company in early 2027. That unit grew 38% (guided +65–75% next year), and the value-unlock helped roughly double the stock to ~$136. The catch: at ~36x earnings, a lot is priced in for a company still mostly a thin-margin (~7%), cyclical manufacturer.

Summary

Finding	Assessment
5-Year Stock Return	$135.80 now vs $13.57 five years ago (+901%, ~10×); an EMS re-rated on AI-datacenter power.
Business Model	Global contract manufacturer — Communications/Lifestyle (ITS), Industrial/Auto/Health (RMS), + AI-datacenter power/cooling (CPI, spinning off).
Competitive Moat	NARROW Thin-margin EMS core; the CPI power/cooling business is differentiated but being spun out.
Past 5-YR Drivers	Data-center/power (CPI) growth, the Nextracker spin, portfolio upgrade, and an aggressive buyback.
Recent Stock Move	$135.80, roughly doubled in 2026 on CPI growth + the spin announcement; +305% over two years.
Revenue Trend	Slight Up YoY revenue growth 16.9%→16.9% (Q4'26→Q1'27E).
Margin Trend	Slight Down Margin 6.7%→6.5% (Q4'26→Q1'27E).
TTM OP Trajectory	Slight Down TTM OP QoQ +6.3%→+5.9% (Q4'26→Q1'27E).
Key Opportunities	Data-center power (CPI +65–75%), the spin-off value-unlock, and margin + buyback.
Key Risks	Rich ~36× valuation, thin margins + CPI dilution + a capex surge, and a cyclical core.
Catalysts	The CPI spin (early 2027), FY2027 delivery, and Investor Day (fall 2026).
P/E(ttm) Valuation	36x — re-rated from single digits; prices the spin + AI growth optimistically.

What Just Reported

Record margins: Q4 revenue $7.5B (+17%) with a record 6.7% adjusted operating margin and adjusted EPS up 27% to $0.93. Full-year FY2026 hit $27.9B (+8%), a record 6.3% margin (a year ahead of target), and a 6th straight year of double-digit EPS growth.
Data center did the heavy lifting. The new Cloud & Power Infrastructure (CPI) segment grew +31% to $1.8B in the quarter (9.9% margin); for the year it rose +38% to $6.6B — with Power (critical/embedded) up 61% and Cloud & Cooling up 29%.
The mature core was mixed. Regulated Manufacturing (industrial, auto, healthcare) grew +5% for the year, while Integrated Technology (communications + consumer) fell −2% on persistent Lifestyle/consumer weakness.

The Big News: Spinning Off the Data-Center Business

Flex announced it will spin off CPI — its AI-datacenter power/cooling business — into a separate public company ("SpinCo"), tax-free, targeted for early 2027. It's a value-unlock, letting the market value the high-growth power franchise separately from the low-margin manufacturing core (the same playbook Flex used with Nextracker).
Leadership splits with it: CEO Revathi Advaithi will run SpinCo (and chair Flex's board), while CCO Michael Hartung becomes CEO of the remaining Flex.
What's left (RemainCo) is a low-single-digit-growth contract manufacturer refocused on healthcare, industrial, robotics and networking — the crown jewel departs.

Guidance & Key Takeaways

FY2027 guidance (pre-spin) was strong: revenue $32.3–33.8B (+18%), adjusted margin 7.0–7.1%, and adjusted EPS $4.21–4.51 (+32%) — with CPI guided to grow +65–75% and then +80%+ in FY2028, "booked out" two years on a multi-year Google contract plus other hyperscalers.
But the AI growth costs money now. CPI's margin dipped this year on ramp costs, and FY2027 capex balloons to $1.4–1.6B (from ~$625M), cutting free-cash-flow conversion to ~60%.
Capital return continues: Flex bought back $944M of stock in FY2026, shrinking its share count ~14% over two years; it pays no dividend.

Key Segments and Revenue Mix (FY2026)

Moat Assessment: NARROW

Contract manufacturing is structurally low-moat. EMS is competitive and thin-margin (~6–7%); Flex competes with Jabil, Celestica, Foxconn and Sanmina across cyclical auto, industrial and consumer markets with limited pricing power.
The data-center power business is the differentiated part. CPI (critical power via Anord Mardix/Crown, liquid cooling via JetCool, "grid-to-chip" integration) has real engineering IP and hyperscaler contracts booked two years out — which is exactly why Flex is spinning it off to surface its value.
But it's narrow overall. Management admits most CPI revenue is still discrete products (the full-architecture moat is aspirational), the mature core has no moat, and after the spin the remaining Flex is a low-single-digit-growth manufacturer — so we rate the combined company NARROW.

Stock vs. Earnings — 5-Year Performance

Stock $135.80, up ~10× over 5 years and +305% over 2 — an extraordinary re-rating for a contract manufacturer. It roughly doubled in 2026 (to a $162 peak, now $136) on data-center growth plus the spin-off announcement.
The business improved steadily, not explosively: revenue is ~$28B (+8%), trailing adjusted operating profit reached $2,003M, and adjusted EPS hit $3.30 (+25%) with a record 6.3% margin.
The multiple did most of the work: P/E ran from a historical ~5–20× to ~36x — the market is now paying a growth multiple for a thin-margin manufacturer, largely on the data-center spin story.

Past 5-Year Key Drivers

Data-center power (CPI). The AI buildout turned Flex's power and cooling business into the growth engine — CPI doubled in two years to $6.6B (+38%) and became the reason to own the stock.
Portfolio simplification. Flex spun out Nextracker (solar) in 2023–24 and de-emphasized low-value consumer work, lifting the adjusted margin from ~5% to a record 6.3%.
Aggressive buyback. A relentless share-repurchase program cut the share count ~14% in two years, compounding EPS on top of operating growth.

Recent Stock Performance & Drivers

Stock $135.80, up ~305% over two years and ~10× over five — a dramatic re-rating for a company that spent FY2024 in outright revenue decline.
It roughly doubled in 2026 (to a $162 peak, now $136) on the data-center (CPI) hypergrowth plus the May spin-off announcement, which lets the market value the high-growth power business separately from the low-margin core.
But the multiple ran ahead of the fundamentals: at ~36× earnings (vs a historical 5–20×), much of the spin's value is already priced into a company that's still ~76% commodity manufacturing.

Opportunities

Data-center power (CPI). $6.6B growing +38% and guided to +65–75% (FY2027) then +80%+ (FY2028), booked out two years; Power +61% (critical/embedded), Cloud & Cooling +29%; Google + hyperscaler/colo/utility contracts.
The spin-off value-unlock. Separating CPI into a standalone AI-infrastructure company (2027) — the Nextracker playbook — could let it trade at a growth multiple while the remaining Flex re-rates on its own merits.
Margin + EPS + buyback. A record 6.3% margin (a year early), adjusted EPS guided +32% to $4.21–4.51, and an aggressive buyback (share count −14% over two years).

Challenges

Rich valuation. At ~36× on a ~7%-margin manufacturer, the stock prices the spin optimistically; if the AI-power narrative cools or the spin slips, the downside is large.
Thin margins + CPI dilution + capex. The core is low-margin; CPI margins are diluted now (recoupment promised later) while FY2027 capex balloons to $1.4–1.6B, cutting free-cash-flow conversion to ~60%.
Cyclical core + concentration. Lifestyle (−9%), automotive and industrial are cyclical; the top-10 customers are 45% of sales (rising), and the remaining Flex is a low-growth manufacturer once CPI departs.

Next 12 Months

Executing the spin (early 2027). Standalone financials, capital structure and the leadership transition — the value-unlock catalyst the stock is pricing.
CPI ramp + FY2027 delivery. Whether CPI hits +65–75% and the combined +18% revenue / +32% EPS guide lands as capex and the cloud ramp digest.
Investor Day (fall 2026) with standalone SpinCo detail — the setup for how the market values the two pieces.

Next 12-24 Months

SpinCo as a standalone AI-infrastructure name. Whether the "grid-to-chip" power/thermal franchise scales into a Vertiv-like growth company — and whether the full-architecture moat becomes real versus discrete products.
RemainCo's re-rating. A low-single-digit-growth manufacturer refocused on healthcare, robotics, automation and networking — valued on its own merits.
Margin recoupment. CPI recovering the ~100bps of ramp dilution (FY2027) and expanding further (FY2028) as the higher-margin Power mix rises.

Flex screens as a steady but unremarkable manufacturer on the scorecard. It sits around 3 passes with a Rule-of-40 near 24% — mid-teens revenue growth and thin ~7% margins, nowhere near a hypergrowth profile — and it spent FY2024 in outright revenue decline.
The stock re-rated on the story, not the scorecard. P/E jumped from ~5–20× to ~36× on the data-center (CPI) hypergrowth and the spin-off value-unlock — the multiple, not the passes, drove the ~2× move.
Cash conversion is the watch item. Free cash flow has slipped toward ~53–60% of operating profit as data-center capex and working capital ramp, and FY2027 capex balloons to $1.4–1.6B — so reported conversion drops to ~60% even as EPS compounds.
