On May 25, 2023, the shareholders of the Company adopted the BancFirst Corporation 2023 Restricted Stock Unit Plan (the "RSU Plan"). The RSU Plan was effective as of June 1, 2023 and for a period of ten years thereafter. The RSU Plan will continue in effect after such ten-year period until all matters relating to the payment of awards and administration of the RSU Plan have been settled. At June 30, 2024 there were 462,175 shares available for future grants. The restricted stock units ("RSU's") vest beginning two years from the date of grant at the rate of 20% per year for five years. The RSUs are settled and distributed as of each vesting date. The fair value of each RSU granted is equal to the market price of the Company’s stock at the date of grant.

The following table is a summary of the activity under the Company's RSU plan.

The Company has had the BancFirst Corporation Directors’ Deferred Stock Compensation Plan (the “Deferred Stock Compensation Plan”) since May 1999. As of June 30, 2024, there are 39,525 shares available for future issuance under the Deferred Stock Compensation Plan. The Deferred Stock Compensation Plan will terminate on December 31, 2030, if not extended. Under the plan, directors and members of the community advisory boards of the Company and its subsidiaries may defer up to 100% of their board fees. They are credited for each deferral with a number of stock units based on the current market price of the Company’s stock, which accumulate in an account until such time as the director or community board member terminates serving as a board member. Shares of common stock of the Company are then distributed to the terminating director or community board member based upon the number of stock units accumulated in his or her account. There were 5,022 and 17,797 shares of common stock distributed from the Deferred Stock Compensation Plan during the six months ended June 30, 2024 and 2023, respectively.

A summary of the accumulated stock units under the Deferred Stock Compensation Plan is as follows:



	June 30, 2024		December 31, 2023
Accumulated stock units		119,115		119,575
Average price	$	42.43	$	40.03
