ASE Technology Director Chang Hung Pen Exercises Options Worth NT$29.58M

What Happened
Chang Hung Pen, a director of ASE Technology Holding Co., Ltd., exercised 300,000 stock options on September 22, 2026, converting them into 300,000 ordinary shares. The reported exercise price was NT$98.60 per share, for a total cash payment of NT$29,580,000. The Form 4 shows a matching disposal entry for 300,000 derivative securities (the options) at $0.00, reflecting surrender/conversion of the options upon exercise. This is an exercise of vested options (not an open-market buy or sale of existing shares).

Context
This was an exercise of stock options (converted into shares) rather than a sale of shares; there is no indication in the filing that the newly acquired shares were immediately sold (no cashless sale reported). The exercise reduces the outstanding options held by the insider per the vesting/grant notes. As always, exercises can be routine (vesting-driven) and do not by themselves signal a buy or sell opinion.
