The filing shows Micallef, who serves as executive vice president and COO of the Dutch‑based semiconductor maker, sold the shares for a total of roughly $226,000, based on the weighted‑average price reported in the Form 4. The post‑transaction value, calculated using the market close on Sept. 15, was $226.35 per share.

The sale was executed under a 10b5‑1 trading plan, a pre‑arranged schedule that allows insiders to sell stock without the risk of insider‑trading accusations because the timing and amount of the trades are set in advance.

NXP Semiconductors (NASDAQ: NXPI) focuses on high‑value semiconductor segments such as automotive, industrial IoT and 5G‑enabled applications. Its product portfolio includes microcontrollers, application processors, communication processors and wireless connectivity technologies like NFC, UWB, BLE and Zigbee.

Despite the insider sale, the company’s recent financial performance has been solid. In the second quarter, NXP reported revenue of $3.5 billion, a 19 % year‑over‑year increase and a 10 % rise from the prior quarter. Management projects third‑quarter revenue of about $3.8 billion, roughly an 18 % gain versus a year earlier.

Investors have been disappointed with the stock’s price movement this year, however. Through Sept. 16, NXP shares were up only 2.2 % including dividends, lagging the S&P 500’s 11.3 % gain and the Nasdaq Composite’s 12.3 % rise.

The SEC Form 4 filing, submitted on Sept. 17, confirms the transaction and provides transparency for shareholders, reinforcing that the sale was pre‑planned and not driven by any material non‑public information.
