SiTime Corporation's stock soared 14.07% during intraday trading on Thursday, driven by the release of exceptional fourth-quarter financial results and the announcement of a transformative acquisition.

The precision timing solutions provider reported adjusted earnings per share of $1.53 for Q4 fiscal 2025, significantly surpassing the consensus estimate of $1.21. Quarterly revenue reached $113.3 million, beating expectations and marking a substantial 66% increase year-over-year. This performance was largely driven by explosive growth in its Communications, Enterprise, and Datacenter business unit, where revenue soared 160%.

Concurrently, SiTime announced a definitive agreement to acquire timing business-related assets from Renesas Electronics for $1.5 billion in cash and stock. The acquired business is projected to contribute approximately $300 million in revenue within 12 months of closing, significantly accelerating SiTime's path toward its $1 billion revenue target. The company also provided optimistic guidance for the first quarter of 2026, expecting continued strong growth. Following these announcements, several analysts raised their price targets on the stock.
