Common Stock Equity Offerings At-the-Market (ATM) Offerings On May 28, 2019, the Company entered into an at-the-market equity offering sales agreement with Stifel, Nicolaus & Company, Incorporated (Stifel), which was amended on April 9, 2021 and May 8, 2024 (the ATM Agreement), pursuant to which the Company may issue and sell shares of its common stock from time to time through Stifel as the Company’s sales agent. Under this amended agreement, the Company pays Stifel a commission equal to 3.0% of the aggregate gross proceeds of any sales of common stock under the agreement. The offering of common stock pursuant to this agreement can be terminated with 10 days written notice by either party. Sales of the Company’s common stock through Stifel, if any, will be made by any method that is deemed to be an “at-the-market” equity offering as defined in Rule 415 promulgated under the Securities Act of 1933.

The Company exhausted all sales under the First Prospectus Supplement. On November 22, 2024, the Company filed a prospectus supplement (the “Second Prospectus Supplement”) to which the Company may offer and sell shares of common stock having an aggregate offering price of up to $45.0 million from time to time through the ATM. The Company records its ATM sales on a settlement date basis. The Company sold 4,547,207 shares under the ATM for the year ended December 31, 2024 resulting in net proceeds of $21.4 million (stock issuance costs were $1.1 million). The Company sold 1,492,148 shares under the ATM for the year ended December 31, 2023 resulting in net proceeds of $6.4 million (stock issuance costs were $0.4 million). Stock-Based Compensation Amendment to 2020 Omnibus Incentive Plan On March 9, 2020, the Board of Directors adopted the Company’s 2020 Omnibus Incentive Plan (2020 Plan).

On February 27, 2024, the Board of Directors approved an increase of 700,000 shares to the authorized number of shares under the 2020 Plan, increasing the total authorized number of shares from 1,800,000 shares to 2,500,000 shares. This increase was approved by the stockholders at the shareholders’ annual meeting on April 19, 2024. The total number of shares of common stock available for issuance under the 2020 Plan was 2,500,000 shares with 1,073,914 shares available for future issuance at December 31, 2024. Stock Options Stock options issued to the Company’s employees, directors and consultants are summarized as follows for the year ended December 31, 2024:

Vested and expected to vest, December 31, 2024 |  |  | 464,940 |  |  | $ | 16.24 |  |  |  | 3.07 |  |  | $ | 184,818 |

During the year ended December 31, 2024, the Company received approximately $42,000 of net proceeds from the exercise of 10,974 stock options. During the year ended December 31, 2024, the Company issued 71,330 stock options to two consultants. These options were assigned a fair value of $1.19 per share (total fair value of $85,000). During the year ended December 31, 2023, the Company issued 35,482 stock options to two consultants. These options were assigned a fair value of $1.77 per share (total fair value of $42,800). The weighted-average grant-date fair value per share of the stock options granted for the years ended December 31, 2024 and 2023, was $2.91 and $4.58, respectively. The fair value was determined using the Black-Scholes pricing model. For expected volatility, the Company concluded that the historical volatility over the option’s expected holding term provided the most reasonable basis for this estimate. For the risk-free interest rate, the Company used U.S. Treasury Note rates, which mature at approximately the same time as the option’s expected holding term or option life determined by using the simplified method. The Company recognized forfeitures of equity-based awards as a reduction to compensation costs in the period in which they occur. The following assumptions were used in the Black-Scholes pricing model to determine the fair value of stock options granted during the years ended December 31, 2024 and 2023:
|  | Year Ended |
|  | December 31, |
|  | 2024 |  |  | 2023 |
Expected volatility |  | 75.36%-92.89% |  |  | 68.13%-95.70% |
Risk free interest rate |  | 3.76%-4.54% |  |  | 4.21%-5.12% |
Dividend yield rate |  |  | — |  |  |  | — |
Expected life |  | 2 - 6 years |  |  | 1 - 6 years |
Closing price per share - common stock |  | $2.49 - $2.62 |  |  | $4.31 - $4.35 |
The intrinsic value is calculated as the difference between the fair value of the Company's common stock and the exercise price of the stock options. The fair value of the Company's common stock was $4.73 and $3.21 per share at December 31, 2024 and 2023, respectively. As of December 31, 2024 and 2023, total unrecognized compensation cost related to option awards was $41,600, which is expected to be recognized over a remaining weighted-average vesting period of 2.06 years. Common Stock Consultants’ Stock Issuances For the year ended December 31, 2024 and 2023, the Company issued 18,201 shares (with stock prices ranging from $3.00 to $4.00 per share with a weighted average stock price of $3.30 per share) and 13,325 shares (with stock prices ranging from $4.00 to $5.82 per share) of common stock, respectively, to its investor relations firm for services provided during the period, recorded to general and administrative expenses. These shares vested immediately upon issuance. The expense recorded for these share issuances was $15,000 for each quarter with a weighted average grant date fair value of $3.30 per share in 2024 and $4.50 per share in 2023, respectively. The shares were valued based on the closing market price of the Company’s common stock on the date of grant. On August 19, 2024, the Board of Directors approved an equity grant valued at $180,000 to a consulting and investment research firm, for corporate advisory services to be provided over a twelve-month period, and preparation and dissemination of a report regarding the Company, which resulted in issuing the consultant 71,713 shares of common stock on the grant date, valued at $2.51 per share. These shares vested immediately upon issuance and are not forfeitable. The compensation cost of $180,000 is recognized on a straight-line basis over the requisite service period. Approximately $66,000 was recorded as consulting expense for the year ended December 31, 2024. As of December 31, 2024, the unrecognized compensation cost of approximately $114,000 was recorded under Prepaid expenses and other current assets on the accompanying consolidated balance sheet, which is expected to be recognized over a remaining service period of 0.6 years. Director Compensation – Equity-Settled Awards On December 4, 2024, the Board of Directors approved an equity grant valued at $500,000 in total to its five directors for the service period and year ended December 31, 2024, which resulted in granting a total of 85,915 shares of common stock, valued on the grant date at $5.82 per share, with a scheduled share release date on January 2, 2025. On November 20, 2023, the Board of Directors approved an equity grant valued at $240,000 in total to its six directors for the service period and year ended December 31, 2023, which resulted in granting a total of 60,456 shares of common stock, valued on the grant date at $3.97 per share, with the shares issued in January 2024. As a result, the fair value of the stock awards was measured on the grant date and recorded as an increase to stock-based compensation expense and additional paid-in capital in 2024. The fair value of the shares granted was determined based on the closing market price of the Company's common stock on the grant date. Restricted Stock Awards The following summarizes the Company’s restricted stock award activity and the RSA outstanding:
|  | Number of Shares |  |  | Weighted- Average Grant Date Fair Value |  |  | Aggregate Intrinsic Value |
