Downturn of 7.56% Comes Nine Days After Results

On Friday, November 13, 2026, SiTime (NASDAQ:SITM) was marked 7.56% lower at USD 434.98, according to market data. Items dated November 11 to 13 carry no company announcement that explains the move, so the percentage reflects the live session alone. On November 4, 2026, the company put out third-quarter numbers covering the period that ended September 30. Revenue of USD 298.7 million climbed about 257% year over year, while non-GAAP Operating Income of USD 129.5 million equalled 43.4% of revenue, versus 18.5% a year earlier. Trailing revenue before the report was listed at USD 467.85 million in market data, so the third quarter alone equals roughly 64% of that twelve-month figure (calculated).

Acquisition Costs and Amortization Widen the Profit Gap

SiTime (NASDAQ:SITM) produces MEMS-based silicon timing components that keep electronic systems synchronized, including inside AI data centres. The business credits its recently added timing unit, acquired on July 1, 2026, for the jump in scale. Non-GAAP Net Income was USD 130.3 million, whereas GAAP net income landed at just USD 4.4 million, as USD 61.8 million of amortization on intangibles and USD 21.3 million in deal expenses weighed on it. Goodwill climbed toward USD 2.0 billion, while net convertible notes stood at roughly USD 1.32 billion, producing USD 5.1 million of quarterly interest. Fourth-quarter guidance was absent from the release and was slated for the Earnings Call instead. A USD 1.2 billion convertible notes offering, upsized and priced on May 19, 2026, according to market data, accounts for the interest burden and could dilute holders on conversion.

Three-for-One Split Plans Meet a Steep Drop From the High

SiTime (NASDAQ:SITM) has announced a three-for-one stock split, so per-share metrics such as the USD 4.01 non-GAAP EPS are pre-split, and no split adjustment was found in the quoted price. The 52-week span in market data runs from USD 243.68 to USD 901.81, leaving the shares roughly 52% under the peak (calculated). AI-linked shares were battered on November 5, 2026, leaving the S&P 500 4.4% lower and Nvidia 9.3% lower, before a November 9 bounce. No confirmed driver for November 12 to 13 turned up. Concerns include absorbing a large acquisition, depending on a small set of AI customers and a valuation that still looks rich against GAAP earnings.

Where Things Stand

The decline seems to reflect swings in AI hardware stocks and a valuation that had already retreated from the 52-week peak, given that the company released nothing fresh today. SiTime (NASDAQ:SITM) posted USD 298.7 million in revenue, healthy non-GAAP margins and a run rate above USD 1 billion, while GAAP earnings look far slimmer after Acquisition amortization. Fourth-quarter targets came only during the call. Watch the split mechanics, fourth-quarter delivery and integration progress. Treat the quoted level as live market data that can change.
