Explanation of Responses:
(1)	These transactions represent the net settlement of share units (see footnote #2) to withhold the Reporting Person's federal, state and local income taxes in connection with the conversion of share units previously awarded to the Reporting Person into shares of Comtech Telecommunications Corp.'s common stock. Share units are rights to convert solely into Comtech Telecommunications Corp. common stock on a one-for-one basis.
(2)	The share units were issued last fiscal year in lieu of cash settlements based on the achievement of pre-established non-equity incentive goals for the fiscal year ending July 31, 2020, pursuant to the 2000 Stock Incentive Plan. These share units were fully vested upon grant and were automatically converted into Comtech Telecommunications Corp.'s common stock on the one-year anniversary of the grant date, which was July 31, 2021.
