Item 5.02.Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

In connection with the recent acquisition of Vista Bancshares, Inc., which closed January 7, 2026, National Bank Holdings Corporation and its controlled subsidiaries (collectively, the “Company”) have implemented strategic organizational enhancements to further support the Company’s long-term growth and integration objectives.   As part of these changes, effective February 13, 2026, Chris Randall, EVP, Head of Commercial, Specialty & Business Banking (former executive officer and named executive officer), assumed a new leadership role as EVP, SBA Delivery.  In conjunction with this transition, Mr. Randall resigned from the boards of directors of NBH Bank and Bank of Jackson Hole Trust.  The Company and Mr. Randall entered into a Transition Agreement memorializing his transition, pursuant to which Mr. Randall: (i) will receive an annual base salary of $250,000; (ii) will be eligible for an annual cash incentive payment with a  target incentive of 30% of base salary pursuant to the terms of the Company’s incentive plan applicable to his new role; (iii) will receive, beginning in 2027, an annual equity award of up to 50% of his base salary, subject to approval by the Compensation Committee of the Board of Directors of the Company.  Additionally, he will receive a one-time equity award equal to such number of restricted common stock that equal in the aggregate a grant date fair value of $25,000, subject to approval by the Compensation Committee of the Board of Directors of the Company. Mr. Randall continues to be eligible to receive benefits in accordance with the terms of the Company’s benefit programs applicable to all other similarly situated associates.  The parties also mutually agreed to the termination of the Change of Control Agreement that was previously entered into between the Company and Mr. Randall.

The foregoing description of the Transition Agreement with Mr. Randall does not purport to be complete and is qualified in its entirety by reference to the full text of such Transition Agreement, which will be filed as an exhibit to a subsequent periodic report filed with the U.S. Securities and Exchange Commission.
