Key Q&A
Q:Where are most of the bookings coming from, given the book-to-bill ratio of 1.5?
A:Most bookings are coming from the CED (Comms, Enterprise, Data Center) segment due to its tremendous growth. Customers are booking in advance to meet demand, and while other business units are also growing, CED represents the largest portion due to its scale.
Q:Can you elaborate on the acquisition and its potential growth opportunities?
A:The acquisition involves 100% of the timing business (TPD) from Renesas. SiTime is exploring integration opportunities with Renesas' microcontrollers, potentially leveraging SiTime's Titan resonators. This partnership could open up several billion dollars in revenue opportunities, with Renesas' CEO joining SiTime's Board to strengthen collaboration.
Q:What is the growth outlook for the core business in 2026?
A:The core business is expected to grow better than the long-term average of 25%-30%, driven by strong demand in AI data centers, automotive, industrial, aerospace, and consumer sectors. Specific opportunities include increased drone and defense applications and design wins in the consumer space.
Q:What cross-selling opportunities exist between SiTime and Renesas?
A:There is minimal product overlap, creating opportunities to introduce SiTime's MEMS oscillators to Renesas' customers. Additionally, SiTime can present integrated solutions to customers in AI, GPUs, accelerator cards, and switches, where Renesas' clocks or competitors' clocks are currently used.
Q:Does the acquisition require China SAMR approval?
A:No, the acquisition does not require China SAMR approval as part of the regulatory process.
Q:What synergies exist between SiTime and Renesas in the data center segment?
A:The synergies focus on timing products, with opportunities to integrate SiTime's oscillators and resonators with Renesas' clocks. This integration can address performance needs like density, power, resilience, and throughput, benefiting AI, data centers, and other sectors.
Q:What is the duration of the backlog for the 1.5x book-to-bill ratio?
A:The backlog is typically within 12 months, with a significant portion weighted towards Q1 and Q2, though some customers are booking into the second half of the year.
Q:What is the expected growth rate for the mobile and consumer business in 2026?
A:The consumer business is expected to grow meaningfully in 2026, driven by design wins ramping up during the year.
Q:What is the long-term gross margin outlook for 2026?
A:Gross margins will be driven by mix, with CED growth being favorable and consumer business potentially offsetting it. Operating leverage is expected to improve, with revenue growth outpacing operating expenses.
Q:What are the OpEx and cost synergies from the acquisition?
A:The acquired timing division operates on a fabless model with similar OSAT processes as SiTime. Specific cost structures and synergies will be detailed post-acquisition closure.
Q:What are the content gains from the 1.6T platforms, and how significant are they for 2026?
A:Content gains on 1.6T platforms are in the tens of percent in ASP, with increased deployment units. This, along with other optical modules and networking products, contributes to a strong business outlook.
Q:What is the growth outlook for the combined SiTime and Renesas business?
A:The combined business is expected to maintain a 25%-30% growth rate, with SiTime's oscillator business growing faster and Renesas' clocking business growing at a slower but healthy rate.
Q:How does the MOU with Renesas position SiTime competitively?
A:The MOU allows SiTime to integrate its Titan resonators into Renesas' microcontrollers, positioning SiTime as a leader in resonator technology. This partnership could serve as a flagship design win and is not exclusive to Renesas.
Q:Are there any new applications driving growth in the CED segment?
A:No new application categories were mentioned, but there are new design wins and increased density of chips used in existing applications, such as ADAS and retimers.
Q:Are there any supply chain constraints affecting growth?
A:No current supply chain constraints are reported. SiTime has resolved past challenges and is confident in its supply chain's ability to support growth. The company also benefits from programmability, quality, and reliability.
Q:What are the details of the acquired timing division's operations?
A:The timing division is fabless, with engineering teams in Ottawa, South San Jose, Tempe, Arizona, and Shanghai. It uses TSMC and GlobalFoundries for manufacturing and has strong back-end connections with ASC and CARSM.
Q:Review of Unclear Management Responses
A:Management avoided providing specific growth rate guidance for 2026, instead offering qualitative insights and emphasizing long-term growth drivers. Additionally, details on the cost structure and synergies from the acquisition were deferred until after the transaction closes.
