Explanatory Note

This Amendment No. 4 hereby amends the Schedule 13D first filed by the Reporting Persons (as defined below) on July 12, 2018, as amended by Amendment No. 1 to the Schedule 13D filed on April 11, 2019, Amendment No. 2 to the Schedule 13D filed on November 27, 2019 and Amendment No. 3 to the Schedule 13D filed on November 23, 2021 (as amended, the “Statement”). The securities to which the Statement relates are the shares of common stock, par value $0.001 per share (the “Common Stock”), of Tricida, Inc., a Delaware corporation (the “Issuer”). Prior to March 22, 2022, Mr. Isern (as defined below) and Dr. Coufal (as defined below) served as co-managers and voting members of the following entities: SCV (as defined below), SCV II (as defined below), SCV III (as defined below), SCV IV (as defined below) and Sibling Insiders LLC (as defined below) (collectively, the “General Partners”). SCV currently serves as the sole general partner of Sibling A (as defined below), SCV II currently serves as the sole general partner of Sibling B (as defined below), SCV III currently serves as the sole general partner of Sibling C (as defined below), SCV IV currently serves as the sole general partner of Sibling D (as defined below) and Sibling Insiders LLC currently serves as the sole general partner of Sibling Insiders Fund (as defined below) (Sibling A, Sibling B, Sibling C, Sibling D and Sibling Insiders Fund collectively, the “Funds”). On March 22, 2022, the governing documents of the General Partners were amended such that Dr. Coufal has been removed as a co-manager of the General Partners and her equity interests therein have been reclassified as non-voting interests and Mr. Isern was appointed as the sole manager of the General Partners and he holds all of the voting interests therein. As a result, Dr. Coufal no longer beneficially owns any shares directly held by the Funds or the shares deemed to be beneficially owned by the General Partners.

Accordingly, the Purpose of this Amendment No.4 is to reflect the following:

(i) The decrease in beneficial ownership of the shares of Common Stock deemed to be beneficially owned by Dr. Coufal;

(ii) That, as a result of the decrease in the shares of Common Stock deemed to be beneficially owned by Dr. Coufal, the shares of Common Stock deemed to be beneficially owned by Dr. Coufal is less than 5.0% and, consequently, Dr. Coufal will no longer be subject to the filing requirements of Section 13(d) of the Act and this Amendment No.4 shall be Dr. Coufal’s “final amendment” to be filed under the Statement;

(iii) That, to the extent Dr. Coufal was deemed to be part of a group within the meaning of Section 13(d) of the Act with the other Reporting Persons, she is no longer a member of any such group; and

(iv) The decrease in beneficial ownership of the shares of Common Stock deemed to be beneficially owned by the remaining Reporting Persons.

Except as otherwise provided herein, each Item of the Schedule 13D remains unchanged. Capitalized terms used herein but not defined in this Amendment No. 4 shall have the meaning ascribed to such term in the Schedule 13D.
