The 2014 Plan, as amended, was approved by the Company’s Board of Directors (the “Board”) During the years ended December 31, 2022 and 2021, the Company granted options to purchase an aggregate of 1,194,032 and 1,895,550 shares of common stock, respectively, to its directors and employees under the 2014 Plan. On June 21, 2022, the Company’s stockholders approved the ADMA Biologics, Inc. 2022 Compensation Plan (the “2022 Equity Plan”). Approval of the 2022 Equity Plan resulted in approximately 18 million additional shares of the Company’s common stock being reserved for future awards. The 2022 Equity Plan provides for the Board or a Committee of the Board (the “Committee”) to grant awards to optionees and to determine the exercise price, vesting term, expiration date and all other terms and conditions of the awards, including acceleration of the vesting of an award at any time. Any options granted under the 2022 Equity Plan are intended to be Incentive Stock Options (“ISOs”), unless specified by the Committee to be Non-Qualified Options (“NQOs”) as defined by the Internal Revenue Code. ISOs and NQOs may be granted to employees, consultants or Board members at an option price not less than the fair market value of the common stock subject to the stock option agreement. For the year ended December 31, 2023, the Company granted options to purchase an aggregate of 1,826,380 shares of common stock to employees and directors under the 2022 Equity Plan.

The fair value of stock options granted was determined on the date of grant using the Black-Scholes model. The Black-Scholes option pricing model was developed for use in estimating the fair value of publicly traded options, which have no vesting restrictions and are fully transferable. The Company’s employee stock options have characteristics significantly different from those of traded options, and changes in the underlying Black-Scholes assumptions can materially affect the fair value estimate. To determine the risk-free interest rate, the Company utilized the U.S. Treasury yield curve in effect at the time of the grant with a term consistent with the term of the awards granted by the Company. The expected term of the options granted is in accordance with Staff Accounting Bulletins 107 and 110, which is based on the average between vesting terms and contractual terms. The expected dividend yield reflects the Company’s current and expected future policy for dividends on the Company’s common stock. For the years ended December 31, 2023, 2022 and 2021, the expected stock price volatility for the Company’s stock options was calculated by examining the historical volatility of the Company’s common stock since the stock became publicly traded in the fourth quarter of 2013. The grant date fair values of stock options awarded during the years ended December 31, 2023, 2022 and 2021 were determined using the Black-Scholes option pricing model with the following assumptions: Years Ended December 31, 2023 December 31, 2022 December 31, 2021 Expected term 5.5-6.3 years 5.5-6.3 years 5.5-6.3 years Volatility 68 % 68 % 68-70 % Dividend yield 0.0 0.0 0.0 Risk-free interest rate 4.20-4.62 % 1.72-1.73 % 0.80-1.27 % The following table summarizes information about stock options outstanding as of December 31, 2023, Shares Weighted Average Exercise Price Options outstanding, vested and expected to vest at December 31, 2020 6,922,931 $ 4.40 Forfeited (529,202 ) $ 2.89 Expired (426,557 ) $ 4.91 Granted 1,895,550 $ 2.14 Exercised - $ - Options outstanding, vested and expected to vest at December 31, 2021 7,862,722 $ 3.93 Forfeited (31,540 ) $ 2.37 Expired (700,324 ) $ 6.86 Granted 1,194,032 $ 1.67 Exercised (68,679 ) $ 2.55 Options outstanding, vested and expected to vest at December 31, 2022 8,256,211 $ 3.37 Forfeited (99,345 ) $ 2.73 Expired (262,940 ) $ 6.42 Granted 1,826,380 $ 3.36 Exercised (3,814,122 ) $ 3.15 Options outstanding, vested and expected to vest at December 31, 2023 5,906,184 $ 3.38 Options exercisable 3,410,131 $ 3.79 As of December 31, 2023, the Company had $3.8 million of unrecognized compensation expense related to stock options granted under the Company’s equity incentive plans, which is expected to be recognized over a weighted-average period of 2.6 years.
