SiTime Corporation reported fourth‑quarter 2025 revenue of $113.3 million, a 66% year‑over‑year increase that lifted total fiscal‑year revenue to $326.7 million, up 61% from the prior year. Non‑GAAP earnings per share rose to $1.53, beating consensus estimates of $1.20–$1.23 by $0.30–$0.33, or roughly 25–27%. Non‑GAAP operating income reached $33.9 million, and the company posted a non‑GAAP gross margin of 61.2%, exceeding its own forecast and underscoring the strength of its high‑margin clocking product mix.
The surge in revenue was driven almost entirely by the Communications, Enterprise and Datacenter (CED) segment, which accounted for 57% of total sales and grew 160% year‑over‑year to $64.6 million. The CED business, powered by AI‑driven data‑center demand, has delivered seven consecutive quarters of double‑digit growth. Other segments—Automotive, Industrial, Aerospace, Consumer, IoT, and Mobile—contributed the remaining 43% of revenue, with modest growth that helped cushion the impact of a slower automotive market.
Margin expansion was largely a result of the product‑mix shift toward higher‑margin clocking solutions and disciplined cost management. Operating income grew 30% to $33.9 million, while the gross‑margin lift to 61.2% reflected both pricing power in the CED market and the scaling of volume production for new MEMS timing products. The company’s operating leverage improved as revenue grew faster than operating expenses, a trend that management highlighted as a key driver of profitability.
Looking ahead, SiTime guided for first‑quarter 2026 revenue of $101–$104 million, a 70% year‑over‑year increase, and non‑GAAP EPS of $1.10–$1.17. The company also projected a 62% gross margin for the quarter and maintained a book‑to‑bill ratio above 1.5, signaling strong demand and visibility. Management emphasized that the upcoming acquisition of Renesas’ timing business, valued at $1.5 billion, will nearly double CED revenue and accelerate the path to a $1 billion annual revenue milestone.
CEO Rajesh Vashist praised the quarter as “another exceptional period” and noted that the company’s “broad‑based growth across all end‑customer segments and regions” was driven by AI. CFO Beth Howe highlighted the milestone of surpassing $100 million in quarterly revenue for the first time and the “accretive” nature of the Renesas transaction. While the company faced no significant headwinds, it acknowledged the need to continue investing in R&D to sustain its competitive edge in the precision‑timing market.
Investors reacted positively to the results, with analysts commending the strong earnings beat, margin expansion, and forward guidance. The market’s enthusiasm reflected confidence in SiTime’s ability to capture AI‑driven demand and execute on its growth strategy.
