During the three and six months ended March 31, 2026 and 2025, stock-based compensation expense related to stock-based awards was included in selling, general and administrative and research and development costs as follows in the accompanying condensed statements of operations.

2025 Equity Incentive Plan

On January 10, 2025, the Board of Directors of the Company adopted the NeuroOne Medical Technologies Corporation 2025 Equity Incentive Plan (the “2025 Plan”). On February 14, 2025, at the 2025 annual meeting of stockholders, the stockholders of the Company approved the 2025 Plan.

The 2025 Plan is the successor to and continuation of the Company’s 2017 Equity Incentive Plan (the “2017 Plan”) and to the Company’s 2016 Equity Incentive Plan (together, the “Prior Plans”). As of the Effective Date, (i) no additional awards may be granted under the Prior Plans; (ii) any Returning Shares will become available for issuance pursuant to Awards granted under the 2025 Plan; and (iii) all outstanding awards granted under the Prior Plans will remain subject to the terms of the Prior Plans (except to the extent such outstanding awards result in returning shares that become available for issuance pursuant to awards granted under the 2025 Plan).

Initially, the maximum number of shares of the Company’s common stock that may be issued under the 2025 Plan may not exceed (1) 500,000 and (2) any shares subject to outstanding stock awards under the 2017 Plan that are forfeited or otherwise returned to the share reserve. See “Note 16 - Subsequent Events”.

Inducement Plan

In October 2021, the Company adopted the NeuroOne Medical Technologies Corporation 2021 Inducement Plan (the “Inducement Plan”), pursuant to which the Company reserved 70,058 shares of its common stock to be used exclusively for grants of awards to individuals who were not previously employees or directors of the Company, as an inducement material to the individual’s entry into employment with the Company within the meaning of Rule 5635(c)(4) of the Nasdaq Listing Rules. The Inducement Plan was approved by the Company’s Board of Directors without stockholder approval in accordance with such a rule. On November 9, 2023, the Company’s Board of Directors adopted the First Amendment to the Company’s Inducement Plan, increasing the aggregate number of shares of common stock that may be issued pursuant to equity incentive awards under the Inducement Plan by 25,000 shares.
