FAQ

What insider transaction did WTBA executive Brad Winterbottom report?

Brad Winterbottom reported a tax-withholding disposition of 6,162 West Bancorporation common shares. The shares were withheld on March 25, 2026 to pay payroll taxes triggered by the vesting and issuance of restricted stock units, not sold in an open-market transaction.

At what price were Brad Winterbottom’s WTBA shares withheld for taxes?

The 6,162 West Bancorporation shares were withheld at $23.71 per share. This price reflects the value used to satisfy payroll tax obligations arising from the vesting and issuance of restricted stock units on March 25, 2026, rather than a voluntary market sale.

How many WTBA shares does Brad Winterbottom hold after this Form 4?

Following the tax-withholding event, Brad Winterbottom held 148,589 West Bancorporation shares directly. He also had 6,607 shares held indirectly by his spouse and 26,058 shares held indirectly through a 401(k) plan, illustrating a substantial remaining ownership position after the withholding.

Did any of Brad Winterbottom’s WTBA performance stock units fail to vest?

Yes. The filing states that 719 previously reported performance stock units did not vest. The units failed because the applicable performance conditions were not satisfied, meaning those shares were never issued to Brad Winterbottom under the company’s performance-based equity program.

Was Brad Winterbottom’s WTBA Form 4 transaction an open-market sale?

No. The Form 4 describes a tax-withholding disposition, not an open-market sale. Shares were automatically withheld by West Bancorporation to pay payroll taxes due when restricted stock units vested and converted into common stock on March 25, 2026.
