MAXCYTE, INC.

Share Repurchase Program

MaxCyte’s board of directors has authorized a share repurchase program for up to $10 million of the Company’s outstanding common stock within a one-year period, unless extended or shortened by the board of directors. Any repurchases would be made in the open market and/or in privately negotiated transactions, and may be made from time to time or in one or more larger repurchases. Repurchases may be made pursuant to one or more trading plans adopted in accordance with Rule 10b5-1, through discretionary open market purchases during periods when the Company's trading window is open, and/or in privately negotiated transactions. Open market purchases are expected to be made in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended.

The Company expects to utilize a majority of the approved $10 million in the short to medium term, however, the amount and timing of any repurchases made under the repurchase program will depend on a variety of factors, including available liquidity, cash flow and market conditions. The program does not obligate the Company to acquire any particular amount of common stock and the program may be modified or suspended at any time at the Company’s discretion.
