AXT (AXTI) CFO Gary L. Fischer Exercises Stock Options

What Happened

Gary L. Fischer, Chief Financial Officer of AXT Inc. (AXTI), exercised multiple stock option grants on February 26, 2026, resulting in the acquisition of 247,828 shares. The exercises were in four tranches: 65,685 shares at $5.21 ($342,219), 34,203 shares at $9.50 ($324,929), 55,500 shares at $5.77 ($320,235), and 92,440 shares at $3.06 ($282,866).

The filing also reports the corresponding disposition of the derivative option interests at $0, reflecting conversion of the options into common stock (not a market sale of the acquired shares).

Key Details

No 10b5-1 plan, tax-withholding sale, or open-market sale of the underlying shares is indicated in the provided details.

Context

These were option exercises (transaction code M). The filing shows the options converted into shares rather than an immediate sale of the acquired shares (i.e., not a cashless sell-to-cover reported here).
Exercises of vested options are common for executives to realize long-held equity awards; the filing is informational and does not, by itself, indicate a buy/sell signal for the company stock.
