​ Stock Options iBio, Inc. 2023 Omnibus Equity Incentive Plan (the “2023 Plan”) On November 27, 2023, the Company’s stockholders approved the adoption of the 2023 Plan for employees, officers, directors and external service providers which is the successor to the 2020 Omnibus Equity Incentive Plan (the “2020 Plan”) and once approved became effective on January 1, 2024. The maximum number of shares of Common Stock reserved and available for issuance under the 2023 Plan is 1,200,000 shares (the “Limit”). In addition, such Limit automatically increases on January 1 of each calendar year commencing on January 1, 2025 and ending on (and including) January 1, 2033, by a number of shares of Common Stock equal to five percent (5%) of the total number of shares of Common Stock outstanding on December 31 of the preceding calendar year; provided, however, that the Board may act prior to January 1 of a given calendar year to provide that the increase for such year will be a lesser number of shares of Common Stock, provided further that the Limit, as in effect at any time, shall be adjusted as a result of any reorganization, recapitalization, reclassification, stock dividend, extraordinary cash dividend, stock split, reverse stock split or other similar change in the Company’s capital stock. The 2023 Plan allows for the award of stock options, stock appreciation rights, restricted stock, restricted stock units, unrestricted stock, cash-based awards, and dividend equivalent rights. The value of all awards awarded under the 2023 Plan and all other cash compensation paid by the Company to any non-employee director in any calendar year may not exceed $500,000; provided, however, that such amount shall be $750,000 for the calendar year in which the applicable non-employee director is initially elected or appointed to the Board and $1,500,000 for any non-executive chair of the Company’s Board should one be appointed. Notwithstanding the foregoing, the independent members of the Board may make exceptions to such limits in extraordinary circumstances. The term of the 2023 Plan will expire on the tenth anniversary of the effective date of the 2023 Plan (December 31, 2033). ​ Vesting of service awards are determined by the Board and stated in the award agreements. In general, vesting occurs ratably on the anniversary of the grant date over the service period, generally three or five years, as determined at the time of grant. Vesting of performance awards occurs when the performance criteria is satisfied. The Company uses historical data to estimate forfeiture rates. In accordance with the provisions of the 2023 Plan, the Limit increased on January 1, 2025 by 458,383 shares of Common Stock for a total number of awards that can be made under the 2023 Plan of 1,658,383 shares. ​ Under the 2023 Plan, 138,150 shares of Common Stock have been issued pursuant to past grants, 2,716,800 shares of Common Stock are reserved for past grants, and the remaining 306,086 shares of Common Stock are available for future grants as of March 31, 2026. ​ iBio, Inc. 2020 Omnibus Equity Incentive Plan (the “2020 Plan”) ​ On December 9, 2020, the Company’s stockholders approved the 2020 Plan for employees, officers, directors and external service providers.
