This amount includes (i) 4,046,291 shares of Class A common stock, par value $0.001 per share (the “Class A Shares”), (ii) 4,334,375 shares of Class B common stock, par value $0.001 per share, (the “Class B Shares” and, together with the Class A Shares, the “Reata Shares”), (iii) 70,808 Class A Shares that certain of the Relevant Stockholders (as defined below) have the right to acquire within 60 days upon exercise of options or restricted stock units (“RSUs”) granted to such Relevant Stockholders, of which options and RSUs to acquire 67,992 Class A Shares are currently exercisable and (iv) 485,317 Class B Shares that certain of the Relevant Stockholders have the right to acquire within 60 days upon exercise of options granted to such Relevant Stockholders, all of which options are currently exercisable. This amount assumes conversion of all Class B Shares held by certain of the Relevant Stockholders, or which certain of the Relevant Stockholders have the right to acquire, into Class A Shares on a one-for-one basis.

(2)

Calculation is based on the sum of 33,331,586 Class A Shares outstanding as of June 30, 2023, plus the Class A Shares that certain of the Relevant Stockholders have the right to acquire upon conversion of the Class B Shares they own or exercise of the options and RSUs such Relevant Stockholders hold. This percentage also assumes conversion of all Class B Shares held by certain of the Relevant Stockholders into Class A Shares on a one-for-one basis. Because each Class B Share is entitled to three votes per share, Biogen Inc. (“Biogen”) beneficially owns Reata Shares representing approximately 36.4% of the voting power of Reata Pharmaceuticals, Inc. (the “Issuer”) (assuming no conversion of Class B Shares and without taking into account options and RSUs granted to certain of the Relevant Stockholders).

(3)	The beneficial ownership of the Class A Shares is being reported hereunder solely as a result of the Support Agreements (as defined below).

Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission by Biogen that it is the beneficial owner of any of the Class A Shares referred to herein for purposes of Section 13(d) of the Exchange Act, or for any other purpose, and such beneficial ownership is expressly disclaimed.
