Director Timothy Chen sells entire 70,592-share stake at $78.85–$81.57 for $5,632,525.20; holdings drop to zero.
Timothy Chen, a Director at Ambiq Micro, Inc., executed 4 separate sales totaling 70,592 shares for $5,632,525.20 on 2026-05-27, eliminating his entire shareholding. The blended average price of $79.79 sits within the 52-week range of $22.12–$85.72 and only 7.1% below the 52-week high, suggesting execution during a period of relative strength for the stock. The company's fundamentals present a material backdrop: net income of $-10,171,000.00 (negative) over the most recent full fiscal year, quarterly revenue of $25,060,000.00 declining 4.7% year-over-year, and a market cap of $1,702,792,563.64. A complete exit by a director from a loss-making, revenue-declining business warrants careful scrutiny, particularly given the scale of the transaction ($5.6M) and the fact that no shares remain post-transaction.
