Cornelissen Bart Jan 4

What Happened

Bart Jan Cornelissen, Senior Vice President and Chief Financial Officer of Xencor (XNCR), sold 3,499 shares on April 10, 2026 at $12.29 per share, generating proceeds of approximately $42,990. The filing notes the disposition was to satisfy withholding taxes tied to the vesting of 14,088 restricted stock units (RSUs), so this was a tax-withholding sale rather than a market-timing trade.

For retail investors, purchases often carry more informational weight; this filing documents a tax-related disposition rather than a discretionary sale for investment reasons.
