Explanation of Responses:
(1)	Each restricted stock unit represents a contingent right to receive one share of EMCORE common stock. The restricted stock units were issued pursuant to the Amended and Restated EMCORE Corporation 2019 Equity Incentive Plan. The restricted stock units vest as to 1/4 of the underlying shares on each of the first four anniversaries of the grant date, subject to the Reporting Person's continued service with the Issuer through the applicable vesting date.
(2)	Each PSU represents a contingent right to receive one share of EMCORE common stock, based on the Issuer's total shareholder return (TSR) compared to pre-established relative TSR goals, based on the TSR of the Russell Microcap Index, that were set by the Compensation Committee of the Board of Directors. The aggregate number of shares issued may range from zero (0) to 200% of the target number of shares reported in column 7 of this report.
(3)	Between zero (0) and 200% of the PSUs will vest, if at all, on March 22, 2024, subject to the Reporting Person's continued service with the Issuer through such date.
(4)	The PSUs were awarded to the Reporting Person for no cash or other similar consideration.
