SiTime Corporation has agreed to acquire key assets from Renesas Electronics Corporation’s timing business, a move that significantly expands SiTime’s scale and brings it closer to its long-term goal of $1 billion in annual revenue.
Under the agreement, SiTime will pay $1.5 billion in cash plus about 4.13 million shares of SiTime common stock, with the final share count tied to a pricing collar based on the company’s recent trading average.
The cash portion will be funded through existing cash and $900 million in committed debt financing from Wells Fargo.
Both boards have unanimously approved the transaction. The deal is expected to close by the end of 2026, subject to regulatory approvals and standard closing conditions. After closing, Renesas CEO Hidetoshi Shibata will join SiTime’s board of directors.
With the acquisition, SiTime is positioning itself as a scaled, pure-play leader in precision timing, with deeper exposure to AI infrastructure and other high-growth semiconductor markets.
The acquired business is expected to generate around $300 million in revenue within 12 months after closing, with gross margins of roughly 70%.
Around three-quarters of that revenue comes from high-growth AI datacenter and communications markets, with the rest tied to industrial and automotive applications.
Focused on Precision Timing solutions
SiTime, founded in 2005 in Santa Clara, California, by Dr Markus Lutz and Dr Aaron Partridge, is a company focused on Precision Timing solutions using MEMS (micro-electromechanical systems) technology. Their products aim to provide better performance, smaller size, lower power consumption, and improved reliability compared to traditional quartz devices.
The company’s technology is utilised across various applications, including AI data centres, automated driving, industrial robots, wearables, and IoT. They have shipped over 4 billion devices.
“This acquisition is a monumental milestone toward fulfilling our vision to transform the timing market and solve our customers’ toughest timing challenges,” said Rajesh Vashist, chairman and CEO of SiTime.
“With Renesas’ timing business, we will increase our clocking portfolio by more than 10x and extend our reach in the fastest growing applications in the timing market, including comms, enterprise and datacenter. Notably, these applications are expected to represent more than 60% of SiTime’s revenue, post-acquisition.”
Strategic partnership alongside the deal
Along with the asset acquisition, the two companies signed a partnership memorandum of understanding to explore integrating SiTime’s MEMS resonator technology into Renesas’ embedded computing products.
“This transaction allows Renesas to sharpen its focus on embedded compute leadership while ensuring our customers have access to SiTime’s cutting-edge MEMS timing technology,” said Hidetoshi Shibata, CEO of Renesas. “We look forward to exploring opportunities for strategic collaboration with SiTime to deliver integrated solutions that power the next generation of intelligent devices that demand performance and efficiency.”
