SiTime to Acquire Renesas’ Timing Business in Landmark Move

SiTime to acquire Renesas’ timing business in a landmark deal that could reshape the precision timing industry. The company announced the agreement on Wednesday and highlighted that the acquired unit is expected to generate nearly $300 million in revenue within 12 months after the deal closes. SiTime emphasized that the business will deliver a robust gross margin of around 70 percent, strengthening its strategy to reach $1 billion in annual revenue.

The acquisition will significantly expand SiTime’s presence in fast?growing markets. According to the company, nearly 75 percent of the acquired revenue is tied to AI datacenters and communications, two sectors with accelerating demand for high?reliability timing solutions. As enterprises adopt AI technologies at scale, SiTime to acquire Renesas’ timing business becomes a strategic move aimed at supporting high?speed cloud systems, servers, and next?generation networking infrastructure.

In addition to the acquisition, SiTime and Renesas have signed a partnership Memorandum of Understanding (MOU) to explore integrating SiTime’s MEMS resonators into Renesas’ embedded computing products. This collaboration opens the door for co?developed solutions that could optimize performance in next?generation devices across industrial, consumer, and automotive segments.

SiTime CEO Rajesh Vashist described the agreement as a pivotal turning point for the company. He noted that SiTime to acquire Renesas’ timing business will expand its product portfolio more than tenfold and elevate its leadership position in the timing market. Vashist added that the demand for high?performance timing components is rapidly increasing across communications, enterprise infrastructure, and hyperscale datacenters, markets that are projected to form more than 60 percent of SiTime’s total revenue after the acquisition is completed.

The Renesas timing division brings a legacy of more than 30 years of innovation. Serving over 10,000 global customers, the business has established a strong reputation for advanced clocking products used in industrial systems, automotive electronics, and AI datacenter infrastructure. With SiTime to acquire Renesas’ timing business, the company plans to leverage its global sales network to accelerate revenue growth once the deal is finalized.

Renesas CEO Hidetoshi Shibata stated that this transaction will allow Renesas to sharpen its focus on embedded computing while ensuring continued customer support during the transition period. Shibata added that Renesas looks forward to partnering with SiTime on the development of new computing solutions that require high performance and exceptional energy efficiency.

Vashist further explained that the company aims to integrate its MEMS resonator technology into microcontrollers, power?management circuits, and related semiconductor components. This initiative, supported by SiTime to acquire Renesas’ timing business, could help chipmakers reduce device size, improve performance, and lower power consumption. The integration aligns with emerging use cases in robotics, advanced driver?assistance systems (ADAS), wearable devices, and AI servers.

SiTime highlighted several long?term benefits expected from the acquisition. These include expanding customer relationships across cloud, automotive, networking, consumer electronics, and industrial markets. SiTime will also gain a wide range of advanced clocking products, including jitter attenuators, synchronizers, and high?precision clock generators. Combining these with SiTime’s MEMS?based oscillators will create high?performance timing solutions uniquely suited for datacenter switches, routers, robotics, and next?generation computing devices.

Financially, the company expects the acquisition to accelerate margins and increase earnings per share within the first year after the transaction closes. SiTime plans to pay $1.5 billion in cash and approximately 4.13 million shares for the assets. The cash portion will be funded through a combination of existing reserves and $900 million in committed financing from Wells Fargo Bank. SiTime also stated it will reduce its debt to less than two times EBITDA within two years.

Both companies' boards have approved the deal, and it is expected to close by the end of 2026, pending regulatory approval. After the transaction, Renesas CEO Hidetoshi Shibata will join SiTime’s board, further strengthening the long?term collaboration envisioned through this acquisition.

SiTime will share additional details about the acquisition during its earnings call scheduled for February 4, 2026. Investors can join the webcast through the company’s official website, where a comprehensive presentation has also been made available.
