The 2018 Coastal Financial Corporation Omnibus Plan (the "2018 Plan") authorizes the Company to grant awards, including but not limited to, stock options, restricted stock units, and restricted stock awards, to eligible employees, directors or individuals that provide service to the Company, up to an aggregate of 500,000 shares of common stock. On May 24, 2021, the Company’s shareholders approved the First Amendment to the 2018 Plan, which increased the authorized plan shares by 600,000. The 2018 Plan replaced the 2006 Plan for new awards. Existing awards will vest under the terms granted and no further awards will be granted under these prior plans. Shares available to be granted under the 2018 plan were 249,028 at September 30, 2024.

The fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model. Expected volatilities are based on historical volatility of the Company’s stock and other factors. The Company uses the vesting term and contractual life to determine the expected life. The risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Compensation expense related to unvested stock option awards is reversed at date of forfeiture.

RSUs provide for an interest in Company common stock to the recipient, the underlying stock is not issued until certain conditions are met. Vesting requirements include time-based, performance-based, or market-based conditions. Recipients of RSUs do not pay any cash consideration to the Company for the units and the holders of the restricted units do not have voting rights. The fair value of time-based and performance-based units is equal to the fair market value of the Company’s common stock on the grant date. The fair value of market-based units is estimated on the grant date using the Monte Carlo simulation model. Compensation expense is recognized over the vesting period that the awards are based. RSUs are nonparticipating securities.
