Ambiq Micro's CEO and a company director dumped millions in stock on September 11, 2026. CEO Fumihide Esaka sold 50,000 shares for $3.168 million under a pre-arranged trading plan, while director Ker Zhang unloaded 10,000 shares for $634,360. Investing reported the moves came as Ambiq Micro shares traded near $63.36.
The insider selling spree didn't stop there. Esaka has offloaded roughly $6.97 million in stock since late August, shedding shares across multiple transactions. Kalkinemedia noted Zhang had also sold shares earlier that month at lower prices, signaling executives believe valuations have peaked.
CEO Dumps $3.2 Million in Shares
Fumihide Esaka sold 50,000 Ambiq Micro shares on September 11 at an average price of $63.36 per share. The $3.168 million sale was executed under a Rule 10b5-1 trading plan—a pre-approved arrangement that lets insiders sell on a fixed schedule. Kalkinemedia confirmed Esaka held 460,460 shares after the transaction.
But the September 11 sale wasn't his only move. Esaka also sold 48,500 shares on August 31, nearly 49,000 on September 1, and 11,027 on September 2. Combined with a 13,500-share sale on September 15 at $60.28, the CEO cashed out roughly $6.97 million in total stock value over two weeks.
Director Zhang Reduces His Stake by One-Third
Director Ker Zhang sold 10,000 shares in two separate transactions on September 11. The first involved 9,100 shares priced between $62.85 and $63.84 per share. The second batch of 900 shares sold between $63.87 and $64.05. Combined, Zhang netted $634,360 and cut his ownership stake by 32.93 percent.
Zhang wasn't a new seller. On September 4, he had already offloaded 185 shares at $56.92 each, pocketing $10,530. His remaining 20,366 shares were worth roughly $1.29 million based on the prevailing stock price. Investing reported no Rule 10b5-1 plan governed these sales—meaning Zhang executed them on an ad-hoc basis.
Analyst Sentiment Stays Bullish Despite Insider Selling
At the time of the reporting, Ambiq Micro shares traded at $60.72, down from the $63-plus levels during the September 11 sales. The stock's 52-week range spanned $22.12 to $91.61—a wide swing suggesting volatility. Analysts maintained an overall positive stance: three Buy ratings, four Holds, and one Sell.
The average price target landed at $82.20, implying roughly 35 percent upside from current levels. That gap between insider selling and bullish analyst calls often signals executives view near-term valuations as stretched, even if long-term prospects remain sound.
