Osterweis Opportunity Fund on SiTime Corporation

Thesis

SiTime is the leading pure-play precision-timing semiconductor company. Adoption is increasing in AI data centers as well as applications such as Apple's iPhone, while its most recent quarter showed broad-based acceleration and 88% growth. The acquisition of Renesas's timing business further supports management's ambitions for strong annual growth and operating margins above 30%. The fund believes precision timing is an underappreciated component of AI infrastructure and views SiTime as the market leader.

We believe precision timing is an underappreciated part of AI infrastructure, and SiTime is the market leader.
