| EBP, Related Party and Party-in-Interest Transactions | Note 6. Related-Party Transactions and Party in Interest Transactions The Plan held 350,160 and 326,523 shares of West Bancorporation, Inc.'s common stock as of December 31, 2025 and 2024, respectively, with a fair value of $7,770,052 and $7,069,214, respectively. During the year ended December 31, 2025, the Plan had purchases of $1,000,509 and sales of $502,341 of West Bancorporation, Inc.'s common stock. Dividend income from West Bancorporation, Inc.'s common stock totaled $335,991. Certain Plan investments are collective trusts and pooled separate accounts managed by Principal Life Insurance Company. Principal Life Insurance Company is the custodian as defined by the Plan, and, therefore, these transactions qualify as party-in-interest transactions. Fees incurred by the Plan for the investment management services are included in net appreciation in fair value of investments, as they are paid through revenue sharing, rather than a direct payment. As described in Note 2, the plan made a direct payment to the third-party administrator of $5,824 which was not covered by revenue sharing.
