Lee Cynthia S. 4

What Happened
Cynthia S. Lee, Senior Vice President, Chief Accounting Officer & Controller of Duke Energy (DUK), had 186 shares withheld to satisfy tax withholding when her restricted stock units (RSUs) vested. Two withholding transactions on Feb 22, 2026: 89 shares at $126.78 ($11,283) and 97 shares at $126.78 ($12,298), for total proceeds of approximately $23,581. This was a tax-withholding disposition of vested RSUs (routine), not an open-market sale as a signal of investment intent.

Context
Withholding shares to pay taxes on vested RSUs is a common, administrative transaction and does not necessarily indicate insider sentiment about the stock. The RSUs converted one-for-one into common shares and a portion was retained to satisfy tax liability (cashless-like withholding). This is not a Section 16 10% owner purchase or a gift.
