William Blair Small Cap Growth Fund on Penguin Solutions

Thesis

Penguin Solutions provides high-performance computing hardware and managed services to enterprises. Quarterly results were positive and revenue guidance was raised as Integrated Memory benefited from favorable memory pricing. The fund sees accelerating demand as AI workloads shift toward inference and believes enterprise and government demand for private AI should support Penguin's high-performance computing solutions. It trimmed the position only after outsized performance made the risk/reward less compelling.

“We continue to believe enterprise and government needs for private AI will drive demand for Penguin’s high-performance computing solutions.”
