Ambiq Micro CFO Jeffrey G. Winzeler sold 26,000 shares of company stock on May 14, 2026.

The transaction yielded approximately $1.8 million, according to SEC filings reported on May 23. The sale followed an exercise of stock options.

The transaction reduced Winzeler's direct holdings by approximately 20.6%. He retains a stake of 100,347 shares. This remaining stake held a value of over $7 million at the time.

The sale followed a significant increase in Ambiq's stock price. First-quarter financial results showed a 59% year-over-year revenue increase.

Surging demand for the company's ultra-low-power artificial intelligence products drove this growth. The transaction reflects profit-taking while maintaining exposure to the company's future.
