SITIME Corp, classified in the Technology sector, is a listed company based in Santa Clara, United States, founded in 2005. Its insiders report their share dealings to SEC (Form 4). In the past year (18 October 2025 to 18 October 2026), 87 filings came from 22 insiders.
No insider bought on the market over the period, while 11 insiders filed 32 sales totalling €113.1M. No amount is published for 3 filings, which the totals therefore leave out. At €88.6M, the sale published on 21 November 2025 by Megachips Corp /FI is the largest of the period.
Compared with its exchange (5,810 companies, median 19 filings), a count of 87 filings is above the norm. The full history, which starts in 2021, counts 1 purchase against 295 sales. The 10-K for the year ended 31 December 2025 shows 326.7 m USD of revenue and -42.9 m USD of net income.
Typically, a trade is published a median of 2 days after it takes place. Section 16 rules allow two business days to file each Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.

Entry is the close on the day after publication, the first price a reader could act on. Prices in the listing currency. Past moves are not a forecast.
This score ranks the purchase within its own market. A position size is suggested only on the venues of the backtested strategy universe; elsewhere, signals stay on watch. Not investment advice.

SiTime Corp. (ticker: SITM) is a U.S. semiconductor company listed on the NASDAQ in the United States and focused on precision timing solutions for the electronics industry. Headquartered in Santa Clara, California, the company designs and sells MEMS-based timing components that are intended to replace legacy quartz-based solutions in a wide range of applications. Its competitive identity is that of a high-value niche supplier, differentiated by timing accuracy, reliability, miniaturization, and system-level integration. ([investor.sitime.com](https://investor.sitime.com/?utm_source=openai))
Founded in 2003 and commercializing products since the mid-2000s, SiTime built its franchise around MEMS oscillators and has since expanded into clock ICs, clock-system-on-chip products, and, more recently, MEMS resonators. That product evolution reflects a deliberate strategy to broaden its technology platform and address more of the critical timing stack. The company describes itself as serving a multibillion-dollar global timing market with a fabless semiconductor model and a supply chain built around the silicon ecosystem. ([investor.sitime.com](https://investor.sitime.com/?utm_source=openai))
From a business-line perspective, SiTime primarily sells MEMS oscillators, clock generators, timing synchronization products, and resonators. Its solutions are used in demanding end markets such as AI data centers, networking infrastructure, automotive, industrial, communications, and selected aerospace and defense applications. This mix gives the company broad end-market exposure while also tying demand to enterprise and infrastructure capex cycles. The newest product introductions are aimed in particular at high-performance computing and AI synchronization use cases, where power efficiency, size, and performance requirements are especially demanding. ([sitime.com](https://www.sitime.com/products?utm_source=openai))
In competitive terms, SiTime has a distinctive position: rather than being a traditional quartz supplier, it relies on proprietary MEMS architecture and deeper timing integration. This allows the company to differentiate on performance, footprint, and, in some cases, system resilience. Its customer base is global, and the company sells through both direct sales and distribution partners, giving it broad geographic reach while keeping its operational base concentrated in California.

Recent developments underscore ongoing innovation momentum. In 2025, SiTime launched its Titan platform for MEMS resonators and announced a planned acquisition of Renesas’ timing business, a strategic move that could expand its portfolio and strengthen its position in precision timing. In spring 2026, the company also reported quarterly results showing strong revenue growth, highlighting current commercial traction, although the stock remains that of a growth-oriented semiconductor company and can therefore be volatile.
