As of the date of this proxy statement, all directors and all NEOs are in compliance with their respective stock ownership guideline obligations. Insider Trading Policy We maintain an insider trading policy governing the purchase, sale, and/or dispositions of the Company’s securities by directors, officers, and employees, as well as the Company itself, that we believe is reasonably designed to promote compliance with insider trading laws, rules and regulations, as well as NASDAQ listing standards. A copy of our insider trading policy was filed as exhibit 19 to our annual report on Form 10-K. No Hedging of UMB Common Stock Our Corporate Governance Guidelines prohibit directors and Executive Officers from engaging in short-term speculative trading in UMB’s securities. Prohibited transactions include (1) a short sale (that is, a sale of borrowed securities by an investor who hopes to buy the securities later at a lower price and thus make a profit), (2) a short sale against the box (that is, a short sale of owned securities to lock in gains or prevent additional losses), (3) a put or call option (that is, a right to sell or buy securities at a specified price within a specified period of time), including a covered call, and (4) a hedge or any other type of derivative or speculative arrangement that has a similar economic effect without the full risk or benefit of ownership. Our non-ExecutiveOfficer employees are not subject to the Corporate Governance Guidelines. 43

The Board believes that this prohibition further aligns the interests of directors and Executive Officers with those of shareholders, facilitates compliance with insider-trading and other applicable laws,
