SiTime Corporation

What they do

SiTime designs and sells silicon-based timing devices: oscillators, clock ICs, resonators and synchronization software built on MEMS, analog mixed-signal, system integration and software expertise. It designs the resonator in-house and integrates it into the clock IC package, unlike quartz-based suppliers and most clock IC vendors. Products are designed into over 400 applications across AI systems, datacenter, communications, enterprise, automotive, industrial, aerospace, defense, mobile, IoT and consumer. Manufacturing is outsourced to third parties for wafers, assembly, packaging and test.

Revenue drivers

• Oscillator systems — Historically the substantial majority of revenue, sold across all target end markets.
• AI datacenter demand — In 2025 the company benefited from strong growth in AI datacenter deployments, which drove the revenue step-up that year.
• Clock ICs, resonators and synchronization software — Additional Precision Timing product lines the company says it will focus on and aggressively expand; the July 2026 Renesas Timing Business acquisition added over 550 clocking products.

Recent performance

Q2 2026 net revenue was $157.4 million, up 127% from $69.5 million a year earlier. GAAP gross profit was $99.1 million (63.0% of revenue), GAAP operating expenses $90.9 million, GAAP income from operations $8.2 million and GAAP net income $18.2 million, or $0.66 per diluted share. Non-GAAP gross margin was 67.1% and non-GAAP net income was $65.6 million, or $2.34 per diluted share. The CEO said every segment grew at least 50% and CED grew 181%. Cash, cash equivalents and short-term investments were $1,921 million at June 30, 2026, including net proceeds from a convertible senior notes offering used to fund the Renesas asset acquisition completed July 1, 2026.

Strategy

Management says it will focus on oscillators, clock ICs, resonators and timing synchronization solutions and aggressively expand in those markets. On July 1, 2026 SiTime completed the acquisition of the Renesas Timing Business, adding over 550 clocking products to the portfolio. The company funded that deal partly with convertible senior notes and granted 109,689 inducement RSUs on August 3, 2026 to 168 newly hired individuals, including 126 employees hired with the acquisition. It also plans to expand sales through distributors, contracted sales representatives and its self-service online store, and to use digital marketing to reach new customers.

Risks

• Customer concentration — The company has historically depended on a limited number of customers for a significant portion of revenue, so loss of a large customer or end customer could significantly reduce revenue.
• No long-term purchase commitments — Orders can be cancelled, reduced or rescheduled with little or no notice, exposing SiTime to inventory risk.
• Supply chain dependence — Third parties provide raw materials, wafer fabrication, assembly, packaging and testing, and failure to meet yields, quality or pricing could prevent on-time shipments.
• Trade policy and tariffs — The 10-K and 10-Q cite tariffs, sanctions and trade barriers, along with a significant portion of operations outside the United States, as risks to the business.

Outlook

The company states it plans to discuss business outlook on its August 5, 2026 conference call but the release text provided does not include specific guidance figures. Management characterizes the Renesas Timing Business acquisition and the combined portfolio as accelerating its leadership across every end market it serves. The 10-K forward-looking section notes expectations regarding revenue, average selling prices, gross margin and expenses, and dependence on a limited number of customers.
