Insights

Insider transactions analyst

Routine tax-withholding using shares; no open-market trading.

CEO David D. Nelson had 6,811 shares of West Bancorporation Inc. common stock withheld at $23.71 per share on March 25, 2026. The footnote explains this covered payroll taxes due when restricted stock units vested and shares were issued.

This F-code event is a tax-withholding disposition, not an open-market sale, so it carries little signaling value about his view of the stock. Following the transaction, he still directly held 117,340 shares, plus indirect holdings of 107,457 shares via a revocable trust and 31,695 shares in a 401(k) plan, indicating a large remaining position.
