Why Flex Ltd. Just Surged 80% — And What Happens When the Spinoff Closes

Flex Ltd., ticker FLEX, surged roughly eighty percent in a single month — and the company hasn't even completed the spinoff that sparked it. Nick and Kasey cover this electronics manufacturing services giant for the first time at Chip Stock Investor, breaking down what drove the run-up, what the proposed spinoff actually is, and whether there is anything left for long-term fundamental investors at today's valuation.

Flex is one of the world's largest electronics manufacturing services companies, competing with Foxconn, Jabil, Celestica, and Sanmina across a global footprint spanning over ninety locations in Asia, Europe, the Middle East, Africa, and the Americas. Unlike the perception that contract manufacturing means cheap labor in Asia, Flex's business increasingly runs on automation and robotics — a structural shift that is compressing cost parity across geographies and driving genuine margin improvement. The spinoff is the centerpiece of this episode. Flex is separating its Cloud and Power Infrastructure segment — referred to as SpinCo in the materials — into a standalone company expected to begin trading by the first quarter of calendar year 2027. This segment posted thirty-eight percent year-over-year revenue growth in fiscal year 2026, with guidance pointing to sixty-five to seventy-five percent growth in fiscal 2027 and over eighty percent in fiscal 2028. The business covers critical power products for utility companies, embedded power systems inside data center servers and racks, thermal management solutions that compete in the same market as Vertiv, and cloud power infrastructure for hyperscalers and neo clouds. SpinCo also carries nearly ten percent adjusted operating margins — roughly double the margin profile of the remaining Flex business.

What stays with Flex after the split is the larger but slower-growing core: twenty-one billion in revenue across Regulated Manufacturing Solutions, covering healthcare and automotive, and Integrated Technology Solutions serving customers like Cisco, Juniper Networks, now part of Hewlett Packard Enterprise, and Teradyne. Growth there is expected in the low to mid-single digits. Margins are trending in the right direction, but this is not a high-margin business.

Nick and Kasey also zoom out on the broader industrial conglomerate breakup theme reshaping the market — from GE Vernova to Honeywell — and how Flex's spinoff fits squarely into that playbook. The prior Flex spinoff, NextPower in 2024, has performed very well for shareholders and gives the SpinCo story some historical credibility. The balance sheet is in reasonable shape for a manufacturer, with enough cash on hand to support bolt-on acquisitions as SpinCo looks to consolidate market share.The valuation discussion is honest: at roughly sixty to seventy times current earnings, this is a momentum trade. The forward picture for fiscal 2028 could look closer to thirty times earnings if growth delivers, but the stock is not cheap by traditional measures.For in-depth stock research and the Semiconductor Insider membership, visit chipstockinvestor.com.
