Share-Based Payment Arrangement [Abstract] |
Stock-Based Compensation | 8. STOCK–BASED COMPENSATION At March 31, 2024, Bancshares had one active stock-based incentive compensation plan with awards outstanding. On March 3, 2020, Bancshares’ Board of Directors established the Prosperity Bancshares, Inc. 2020 Stock Incentive Plan (the “2020 Plan”), which was approved by Bancshares' shareholders on April 21, 2020. The 2020 Plan authorizes the issuance of up to 2,500,000 shares of common stock upon the exercise of options or pursuant to the grant or exercise, as the case may be, of other awards granted under the 2020 Plan, including incentive stock options, nonqualified stock options, stock appreciation rights, shares of restricted stock and restricted stock units. As of March 31, 2024, 406,757 shares of restricted common stock have vested and 540,297 shares of unvested restricted stock have been issued under the 2020 Plan. As of March 31, 2024, the Company had no stock options outstanding. Stock-based compensation expense related to restricted stock was $3.4 million and $3.2 million during the three months ended March 31, 2024 and 2023, respectively. As of March 31, 2024, there was $28.0 million of total unrecognized compensation expense related to stock-based compensation arrangements. That cost is expected to be recognized over a weighted average period of 1.95 years.
