Explanation of Responses:

Id Content
F1 Mr. Bylund was awarded 6,435 restricted stock units. Each restricted stock unit represents a contingent right to receive one share of Repligen Corporation's Common Stock. The restricted stock units vest in equal annual instalments over a three-year period beginning on the first anniversary of the grant date. The restricted stock units may be settled only by delivering shares of Repligen Corporation's Common Stock, and thus, the grant is being reported in Table 1 as allowed per SEC guidance.
F2 Represents the number of shares withheld by the Issuer to satisfy tax withholding obligations of the reporting person that arose upon the release of restricted stock units.
F3 One third of the stock options will vest and become exercisable annually on March 3, 2026, March 3, 2027, and March 3, 2028.
