Tily Gil C. 4

What Happened

• Tily Gil C., a director of Amkor Technology, had previously granted RSUs vest on May 13, 2026: approximately 9,893 RSUs converted into common stock on a one-for-one basis (no cash paid). A very small fractional portion (0.0573 RSU) was settled in cash as a dividend equivalent. In addition, the director was granted 2,613 new RSUs on May 13, 2026 as compensation for board service (award).
• Transaction amounts and prices reported: conversion/acquisition of ~9,893 shares at $0.00; a corresponding derivative disposition for ~9,893.057 units at $0.00 reflecting the cash settlement of the fractional DEU; grant of 2,613 RSUs at $0.00. No cash proceeds or purchase price was involved.

• Footnotes of note:
  • F1: The vested RSUs were from a May 15, 2025 award; 0.0573 RSU was settled in cash as a dividend equivalent and the remainder (including 104 DEUs) converted one-for-one to common stock.
  • F2: The 2,613 RSUs granted on May 13, 2026 will vest in full on the earlier of the first anniversary of the grant or the next annual meeting; awarded solely for service as a director.
• Transaction codes: M = exercise/conversion of derivative (RSU conversion); A = award/grant.

Context

• This is a routine compensation event (RSU vesting and new RSU grant), not a market purchase or sale. Converting RSUs to shares is not a bullish or bearish trade signal by itself—it's the normal settlement of equity compensation. The small fractional RSU was cashed out rather than converted, which is standard practice for fractional amounts.
