Explanation of Responses:

( 1 )This reflects the number of restricted stock units that vested on March 1, 2025. ( 2 )Represents the number of shares required to be sold by the Reporting Person to cover tax withholding obligations in connection with the vesting of restricted stock units on March 1, 2025. This sale is mandated by the Issuer's election under its equity incentive plans to require the satisfaction of tax withholding obligations to be funded by a "sell to cover" transaction and does not represent a discretionary trade by the Reporting Person. ( 3 )The reported price in Column 4 is a weighted average sale price. These shares were sold on March 4, 2025 in multiple transactions at prices ranging from $18.34 to $18.77 per share. The Reporting Person undertakes to provide to the Issuer, any security holder of the Issuer, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares purchased at each separate price within the range set forth in this footnote. ( 4 )Each restricted stock unit represents a contingent right to receive one share of Axogen, Inc. common stock. ( 5 )All shares of Axogen, Inc. common stock underlying the restricted stock units will be fully vested on March 1, 2027 based on a vesting schedule whereby 50% of the aggregate shares vest on March 1, 2025, and an additional 25% of the aggregate shares vest each twelve months thereafter. Vested shares will be delivered to the Reporting Person upon the vesting date. The RSUs were granted pursuant to an inducement award agreement outside of the Issuer's Amended and Restated 2019 Long-Term Incentive Plan as a material inducement to the Reporting Person's acceptance of employment with the Issuer in accordance with NASDAQ Listing Rule 5635(c)(4).

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
