Flex (FLEX): Revisiting Valuation After a Multi‑Year Share Price Rerating

Flex (FLEX) has quietly turned into one of the market’s steadier compounders, with the stock up roughly 64% this year and about 3x over the past 3 years.

See our latest analysis for Flex.

The stock’s 30 day share price return of 11.59 percent on a last close of 63.55 dollars builds on strong year to date momentum. Flex’s three year total shareholder return above 300 percent shows this has been a sustained, rerating story rather than a quick trade.

Given that kind of run, it can be worth seeing what else fits a similar profile, so you might also explore fast growing stocks with high insider ownership as a source of fresh ideas beyond Flex.

With shares already tripling in three years and analysts still seeing upside, Flex now sits at the crossroads of strong execution and lofty expectations. This raises the question: is there still a buying opportunity, or is future growth fully priced in?

Most Popular Narrative Narrative: 13.6% Undervalued

With Flex closing at 63.55 dollars against a narrative fair value in the low 70s, the current setup implies meaningful upside if the long term thesis lands.

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, as evidenced by the 35% forecasted annual increase in its data center segment, supporting both topline expansion and higher portfolio margins. Flex's global manufacturing footprint, especially its ability to regionalize and rapidly scale production across North America and Europe, aligns with accelerating customer efforts to de risk and diversify supply chains.

Read the complete narrative.

Curious how modest top line growth, rising margins, and a richer yet lower future earnings multiple can still point to upside from here? The narrative breaks down the earnings bridge, buyback impact, and valuation path that together underpin this fair value call.

Result: Fair Value of $73.51 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, concentrated hyperscaler exposure and structurally thin margins mean that any client loss or pricing pressure could quickly derail the current upside narrative.

Another Angle on Valuation

On earnings, the picture looks less forgiving. Flex trades on roughly 26.8 times profit versus about 24.9 times for the US Electronic industry, yet our fair ratio suggests the market could justify closer to 32 times. Is this a margin of safety or a premium with little room for missteps?
