Item 1 of the Schedule 13D is hereby amended by adding the following:

This Amendment No. 16 to Schedule 13D (“Amendment No. 16”) is being filed by the undersigned, pursuant to §240.13d-2(a), with respect to the Class A Common Stock, $0.001 par value per share (the “Shares”), of Reata Pharmaceuticals, Inc. (the “Issuer” or the “Company”), whose principal executive offices are located at 2801 Gateway Drive, Suite 150, Irving, TX 75063. This Amendment No. 16 amends and supplements the statement on the Schedule 13D filed with the Securities and Exchange Commission (the “SEC”) on June 6, 2016, as amended by Amendment No. 1, filed with the SEC on June 28, 2016, Amendment No. 2, filed with the SEC on July 1, 2016, Amendment No. 3, filed with the SEC on August 9, 2016, Amendment No. 4, filed with the SEC on August 19, 2016, Amendment No. 5, filed with the SEC on December 6, 2016, Amendment No. 6, filed with the SEC on December 20, 2016, Amendment No. 7, filed with the SEC on January 4, 2017, Amendment No. 8, filed with the SEC on March 6, 2017, Amendment No. 9, filed with the SEC on June 23, 2017, Amendment No. 10, filed with the SEC on August 3, 2017, Amendment No. 11, filed with the SEC on November 13, 2017, Amendment No. 12, filed with the SEC on December 29, 2017, Amendment No. 13, filed with the SEC on July 31, 2018, Amendment No. 14, filed with the SEC on December 30, 2020, and Amendment No. 15, filed with the SEC on August 1, 2023 (collectively, the “Schedule 13D”). Capitalized terms used herein and not otherwise defined in this Amendment No. 16 have the meanings set forth in the Schedule 13D.

Item 4 of the Schedule 13D is hereby amended by adding the following:

As previously disclosed in Amendment No. 15, on July 28, 2023, the Issuer entered into the Merger Agreement with Parent and Merger Sub.

On September 26, 2023, the Issuer consummated the Merger.  At the effective time of the Merger (the “Effective Time”), (a) each Share and Class B Share (the Shares and Class B Shares collectively, the “Common Stock”) issued and outstanding immediately prior to the Effective Time, was canceled and extinguished and automatically converted into the right to receive $172.50 in cash (the “Merger Consideration”), without interest and subject to any applicable withholding taxes, and (b) each of the Issuer’s outstanding unexercised stock options (“Stock Options”), whether vested or unvested, was automatically canceled and terminated and converted into the right to receive an amount in cash, without interest, equal to the product of (i) the number of shares of the Issuer’s Common Stock underlying such option immediately prior to the Effective Time multiplied by (ii) the amount, if any, by which the Merger Consideration exceeds the exercise price per share of such option, subject to any applicable withholding taxes.

In connection with the Merger, at the Effective Time, the following shares of Common Stock beneficially owned by the Reporting Persons were cancelled and extinguished in exchange for the Merger Consideration:

Also in connection with the Merger, at the Effective Time, the following shares of Common Stock and Stock Options beneficially owned by Mr. McGaughy were cancelled and extinguished in exchange for the applicable Merger Consideration:

Also in connection with the Merger, at the Effective Time, 31,467 Shares held by The 2:22 DNA Trust, of which Mr. Desai is trustee and has shared voting and investment control with his spouse, were cancelled in exchange for the Merger Consideration:

As a result of the Merger, the Reporting Persons beneficially own no Shares.

As a result of the Merger, the Shares will be delisted from The Nasdaq Stock Market and deregistered under Section 12 of the Act.

Item 5 (a)-(c) and (e) of the Schedule 13D is hereby amended by adding the following:

(a, b) As a result of the Merger, each of the Reporting Persons may be deemed to be the beneficial owner of 0 Shares, which represents beneficial ownership of 0.0% of the Shares outstanding.

(c) The response to Item 4 of this Amendment No. 16 is incorporated by reference herein.  Other than as reported in this Amendment No. 16, none of the Reporting Persons has effected any transaction in the Shares since the most recent filing of Schedule 13D (Amendment No. 15) on August 1, 2023.

(e) As a result of the consummation of the Merger on September 26, 2023, each of the Reporting Persons ceased to be the beneficial owner of more than five percent of the Shares. The filing of this Amendment No. 16 represents the final amendment to the Schedule 13D and constitutes an exit filing for each of the Reporting Persons.

SIGNATURE

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.

Attention: Intentional misstatements or omissions of fact constitute federal violations (see 18 U.S.C. 1001).
