Flex Ltd. (NASDAQ: FLEX) has transitioned from a small-cap option into a multi-billion-dollar enterprise, largely driven by the explosive growth of artificial intelligence (AI) infrastructure. This rapid expansion, however, has triggered mandatory portfolio reallocations among investment managers bound by strict style limitations.
FLEX Outgrows the Small-Cap Mandate
In its second-quarter 2026 investor letter, the Artisan Small Cap Fund announced it has reallocated capital away from Flex Ltd. The decision was not driven by deteriorating fundamentals, but rather by the company’s sheer scale. With a market capitalization reaching $43.42 billion, FLEX has outgrown the small-cap strategy mandate, prompting the fund managers to seek more fitting small-cap opportunities within their investable universe.
FLEX has established itself as a critical player in global manufacturing and supply chain solutions, specifically servicing the high-margin AI and cloud data center infrastructure sectors. The company specializes in manufacturing essential power and cooling systems required to run high-performance AI chips.
