John Marshall Bancorp, Inc.

The number and kind of shares reserved for issuance under the 2025 Plan, and the number and kind of shares subject to outstanding awards and the exercise price of stock options or the amount, if any, payable in respect of an award of shares of restricted stock or restricted stock units, will be proportionately adjusted for any increase, decrease, change or exchange of shares of the Company’s common stock for a different number or kind of shares or other securities of the Company which results from a merger, consolidation, recapitalization, reorganization, reclassification, stock dividend, split-up, combination of shares, or similar event in which the number or kind of shares is changed without the receipt or payment of consideration by the Company. In the event that any such adjustment would result in a participant being entitled to exercise for or receive a fractional share, then upon such adjustment, the number of shares which may be acquired upon exercise or vesting of such award will be rounded down to the next whole share, and such fraction cancelled, and the participant will not be entitled to any payment, compensation or alternative award in lieu thereof.
