Explanation of Responses:

Id	Content
F1	Includes an aggregate of 894 shares acquired by the Reporting Person through the Issuer's Employee Stock Purchase Plan subsequent to the date of the Reporting Person's most recent filing on Form 4.
F2	The option vests in four equal annual installments beginning on February 22, 2023.
F3	Each restricted stock unit represents the right to receive one share of Supernus common stock upon vesting.
F4	The Reporting Person is amending Form 4 filed on February 24, 2022 to reflect that these restricted stock units will be settled in common stock upon vesting, which will occur in four equal annual installments, beginning on February 22, 2023, rather than such vesting occurring entirely on February 22, 2023.
