Ambiq Micro's CFO Sold Company Shares Worth $1.8 Million. Here's What That Means for Investors.

Ambiq Micro's CFO Jeffrey Winzeler sold 26,000 shares worth $1.8 million on May 14, 2026, representing 20.58% of his direct holdings. The sale followed a stock option exercise and occurred as shares surged to 52-week highs, likely capitalizing on gains. The company reported 59% year-over-year revenue growth driven by AI demand, but the stock's price-to-sales ratio has jumped to 20, suggesting shares are now expensive despite strong fundamentals.
