“During the quarter, we initiated new positions in Semtech, Tradeweb Markets and SiTime Corporation (NASDAQ:SITM). SiTime develops silicon-based timing solutions used across communications, data center and industrial applications. We initiated a GardenSM position as we believe the company is well placed to take advantage of the transition from legacy quartz timing solutions to higher performance, silicon-based miniaturized mechanical and electromechanical devices. Increasing content in AI-driven infrastructure has also been supporting sustained growth. With multiple catalysts emerging, including data center upgrades and new product expansion, we see a potential path to accelerating revenue growth and operating leverage. We used the recent pullback to opportunistically begin building a position.”
