Stock Compensation Plans |
Stock Compensation Plans | Note 19: Stock Compensation Plans The Company established the 2013 Equity Incentive Plan (the “2013 Plan”) for employees and directors of the Company and its subsidiaries. Under the plan, stock options or other awards could be granted with respect to 700,000 shares of common stock. On May 9, 2018, the Company’s stockholders approved the Great Southern Bancorp, Inc. 2018 Omnibus Incentive Plan (the “2018 Plan”). Upon the stockholders’ approval of the 2018 Plan, the 2013 Plan was frozen. As a result, no new stock options or other awards may be granted under the 2013 Plan; however, existing outstanding awards under the 2013 Plan were not affected. At December 31, 2024, 124,676 options were outstanding under the 2013 Plan. The Company established the 2018 Plan for employees and directors of the Company and its subsidiaries. Under the plan, stock options or other awards could be granted with respect to 800,000 shares of common stock. On May 11, 2022, the Company’s stockholders approved the Great Southern Bancorp, Inc. 2022 Omnibus Incentive Plan (the “2022 Plan”). Upon the stockholders’ approval of the 2022 Plan, the 2018 Plan was frozen. As a result, no new stock options or other awards may be granted under the 2018 Plan; however, existing outstanding awards under the 2018 Plan were not affected. At December 31, 2024, 492,658 options were outstanding under the 2018 Plan. The 2022 Plan provides for the grant from time to time to directors, emeritus directors, officers, employees and advisory directors of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares and performance units. The number of shares of common stock available for awards under the 2022 Plan is 900,000 (the “2022 Plan Limit”). Shares utilized for awards other than stock options and stock appreciation rights will be counted against the 2022 Plan Limit on a 2.5-to-1 basis. At December 31, 2024, 589,987 options were outstanding under the 2022 Plan. Stock options may be either incentive stock options or nonqualified stock options, and the option price must be at least equal to the fair value of the Company’s common stock on the date of grant. Options generally are granted for a 10-year term and generally become exercisable in four cumulative annual installments of 25% commencing two years from the date of grant. The Compensation Committee has discretion to accelerate a participant’s right to exercise an option. Stock awards may be granted upon terms and conditions determined solely at the discretion of the Compensation Committee. The table below summarizes transactions under the Company’s stock compensation plans, all of which related to stock options granted under such plans: ​

​ The Company’s stock option grants contain terms that provide for a graded vesting schedule whereby portions of the options vest in increments over the requisite service period. These options typically vest one-fourth at the end of each of years two, three, four and five from the grant date. As provided for under FASB ASC 718, the Company has elected to recognize compensation expense for options with graded vesting schedules on a straight-line basis over the requisite service period for the entire option grant. In addition, ASC 718 requires companies to recognize compensation expense based on the estimated number of stock options for which service is expected to be rendered. The Company’s historical forfeitures of its share-based awards have not been significant. Forfeitures are estimated annually based on historical information. The fair value of each option award is estimated on the date of the grant using the Black-Scholes option pricing model with the following assumptions for the years ended December 31, 2024, 2023 and 2022: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | 2024 |  | 2023 |  | 2022 |

Expected dividends per share | ​ | $ | 1.60 | ​ | $ | 1.60 | ​ | $ | 1.60 |
Risk-free interest rate |  | ​ | 4.31 | % | ​ | 4.51 | % | ​ | 3.77 | %
Expected life of options |  | ​ | 6 years | ​ | ​ | 6 years | ​ | ​ | 6 years | ​
Expected volatility |  | ​ | 25.48 | % | ​ | 23.69 | % | ​ | 23.70 | %
Weighted average fair value of options granted during year | ​ | $ | 15.01 | ​ | $ | 11.69 | ​ | $ | 13.46 | ​
​ Expected volatilities are based on the historical volatility of the Company’s stock price over the measured period. The expected life of options granted is based on actual historical exercise behavior of all employees and directors and approximates the graded vesting period of the options. Expected dividends are based on the annualized dividends declared at the time of the option grant. The risk-free interest rate is based on the average of the five-year treasury rate and the seven-year treasury rate on the grant date of the options. The following table presents the activity related to options under all plans for the year ended December 31, 2024: ​
