WINTERBOTTOM BRAD L 4

What Happened

• Brad L. Winterbottom, Executive Vice President of West Bancorporation (WTBA), was granted 15,000 restricted stock units (RSUs) on 2026-02-23. The grant is reported as an award (price $0.00), so there was no cash purchase. This is a compensation award rather than an open-market buy or sale.

Key Details

• Transaction date: 2026-02-23; Form 4 filed 2026-02-24 (timely filing).
• Transaction type: A = Award/Grant; reported price: $0.00.
• Grant breakdown (footnote F1): 7,500 RSUs vest in five equal annual installments beginning March 25, 2027 (1,500 per year); the other 7,500 RSUs cliff vest on March 25, 2029, subject to performance criteria set by the Compensation Committee.
• Other notes from filing:
  • F2: 325 previously reported performance stock units did not vest because applicable performance conditions were not met.
  • F3: 1,934 shares were acquired via dividend reinvestment in the employee 401(k) plan during 2025.
• Shares owned after the reported transaction are not provided in the summary supplied.

Context

• RSU grants are common executive compensation and do not require cash outlay; value is realized only as units vest (and any performance conditions are met). The portion of the grant subject to performance (7,500 RSUs) may not vest if targets aren’t achieved. The filing shows routine compensation activity rather than a market buy or sell.
