Chen Yun-Lung 4

What Happened

• Chen Yun‑Lung, Vice President, Business Development and M, is reported to have exercised/converted a derivative covering 4,651 shares on March 17, 2026 (listed as both an acquisition and a $0.00 disposition on the Form 4). On March 18, 2026 he was granted 2,849 fully‑vested restricted stock units (RSUs) as payment of his Fiscal Year 2026 annual bonus. The RSUs are reported at $0.00 (i.e., compensation awards), and the form shows no cash proceeds from the derivative entries.

  • F3: A performance‑based RSU granted April 3, 2023 vested at 100% of target on March 15, 2026 based on company performance metrics (TSR and revenue growth).

Context

• These entries reflect compensation and a derivative conversion rather than an open‑market buy or sale. RSU awards are compensation and do not necessarily indicate insider market sentiment. The $0.00 pricing on the Form 4 entries indicates stock‑settled awards/conversions or internal accounting treatment; the filing does not show proceeds from an open‑market sale.
