Warren Chen, a director of Diodes Incorporated, was granted 3,000 shares of common stock as a compensation-related award under a Rule 16b-3 plan. The grant carries a zero-dollar transaction price, consistent with share-based compensation rather than an open-market purchase.

The award is structured as restricted stock units that vest in four equal installments starting on May 26, 2027, spreading the benefit over time and tying value to continued service. After this transaction, Chen directly owns 13,140 shares, with no derivative positions shown in the excerpt.
