Flex (FLEX): Valuation in Focus After Power Management Deal With Renesas Targets AI Data Center Growth

Simply Wall St

Flex (FLEX) just made headlines with its Power Modules subsidiary announcing a new partnership with Renesas, a major name in semiconductor technology. This collaboration aims to bring next-generation power management solutions to AI-focused data centers, promising faster design cycles and lower system costs. For investors, this step looks well timed as AI workloads continue to reshape IT and power infrastructure investment, making the event especially relevant for those weighing Flex’s role in the rapidly expanding data center space.

Over the past year, Flex’s stock has caught attention with a strong 78% return, and momentum has only gained speed this year with a surge of more than 50%. This is not happening in a vacuum, as Flex has posted healthy revenue and net income growth while pursuing new tech partnerships and responding to broader AI industry shifts. The partnership with Renesas highlights management’s determination to keep Flex in the mix for next-generation AI hardware opportunities.

After such a rapid climb, the key question for prospective buyers is clear: Is Flex still undervalued, or is the market already incorporating the growth that partnerships like this could provide?

Most Popular Narrative: Fairly Valued

According to the most widely followed narrative, Flex is trading very close to fair value. Analysts' consensus shows little difference between the current share price and their fair value estimate.

The ongoing surge in demand for data center and AI infrastructure, requiring integrated power, cooling, and advanced IT hardware, positions Flex for sustained, outsized revenue growth. This is evidenced by the 35% forecasted annual increase in its data center segment, supporting both topline expansion and higher portfolio margins.

Curious about the hidden financial drivers behind Flex's fair value? The story centers on high-margin segments, a major revenue shift, and future profit multiples you might not expect from a name like this. Want to know what the consensus sees in Flex’s future? The numbers behind the current price may surprise you.

Result: Fair Value of $57.86 (ABOUT RIGHT)
