In addition, on the Closing Date, 61,118,645 of the Class B ordinary shares were received pursuant to the terms of the Business Combination Agreement in exchange for historical interests held by the Reporting Person in ProKidney contemplated by the Business Combination Agreement.

The foregoing description of the Subscription Agreement and the Business Combination Agreement does not purport to be complete and is qualified in its entirety by reference to the form of the Subscription Agreement for Institutional Investors, which is filed as Exhibit 2 and Exhibit 6 to this Schedule 13D and is incorporated by reference herein.

Each Reporting Person acquired the securities described in this Schedule 13D for investment purposes and intends to review its investments in the Issuer on a continuing basis.

Subject to the terms and conditions of the documents described herein to which a Reporting Person is a party, such Reporting Person may engage in discussions with management, the board of directors of the Issuer (the “Board”), other securityholders of the Issuer, industry analysts and other relevant parties.

The Reporting Persons may also enter into confidentiality or similar agreements with the Issuer and, subject to such an agreement or otherwise, exchange information with the Issuer.

Other than as described above, no Reporting Person currently has any plans or proposals that relate to, or would result in, any of the matters listed in Items 4(a)–(j) of Schedule 13D, although depending on the factors discussed herein, any Reporting Person may change its purpose or formulate different plans or proposals with respect thereto at any time.

(c) Except as set forth in this Schedule 13D, no Reporting Person has effected any transaction in Issuer Class A ordinary shares in the past 60 days.

Registration Rights Agreement

On July 11, 2022, the Issuer, CEC and certain other shareholders of the Issuer (the “Registration Rights Holders”) entered into that certain Amended and Restated Registration Rights Agreement (the “Registration Rights Agreement”). The Registration Rights Agreement provides that the Issuer will, within 30 days after the Closing, submit or file with the SEC a shelf registration statement registering the resale of the Issuer Class A ordinary shares held by Registration Rights Holders and will use its commercially reasonable efforts to have such registration statement declared effective as soon as practicable after the submission or filing thereof, but in no event later than (a) 90 days following the submission or filing deadline, if the SEC notifies the Issuer that it will “review” such registration statement and (b) the tenth business day after the date the Issuer is notified (orally or in writing, whichever is earlier) by the SEC that the registration statement will not be “reviewed” or will not be subject to further review. In addition, the Registration Rights Holders have certain “piggy-back” registration rights pursuant to the Registration Rights Agreement. The Issuer will bear the expenses incurred in connection with the filing of any registration statements filed pursuant to the terms of the Registration Rights Agreement. The Issuer and the Registration Rights Holders agree in the Registration Rights Agreement to provide customary indemnification in connection with any offerings of Issuer Class A ordinary shares effected pursuant to the terms of the Registration Rights Agreement.

Lock-Up Agreement

On July 11, 2022, the Issuer, SCS Sponsor III and certain direct and indirect holders of Issuer Class A ordinary shares and Class B ordinary shares, of the Issuer entered into that certain Lock-Up Agreement (the “Lock-Up Agreement”). The Lock-Up Agreement contains certain restrictions on transfer with respect to the SCS Sponsor III and the unitholders party thereto, including Tolerantia. Such restrictions begin at the Closing and end on the earlier of (i) the date that is 180 days after the Closing and (ii)(a) for 33% of the Lock-Up Shares (as defined therein) (other than the Earnout Shares (as defined therein) and the PIPE Shares (as defined therein)), the date on which the last reported sale price of a Class A ordinary share equals or exceeds $12.50 per share for any 20 trading days within any 30-trading day period commencing at least 30 days after the Closing and (b) for an additional 50% of the Lock-Up Shares (other than the Earnout Shares and the PIPE Shares), the date on which the last reported sale price of a ProKidney Class A ordinary share equals or exceeds $15.00 per share for any 20 trading days within any 30-trading day period commencing at least 30 days after the Closing. Notwithstanding the above, (i) the lock-up period for any Earnout Shares will expire not earlier than 180 days after such Earnout Shares are issued; (ii) 50% of the Lock-Up Shares held by Tolerantia and certain other Closing ProKidney Unitholders (as defined therein) and their affiliates will remain locked up until the earlier of four years following the Closing and the date that ProKidney receives notice of any regulatory market authorization, including full or conditional authorization, to market its lead product candidate, Renal Autologous Cell Therapy (but, in any event, not earlier than 180 days following the Closing or (in the case of Earnout Shares) the date of issuance); and (iii) the lock-up period for the PIPE Shares will expire 30 days after the Closing. The restrictions on transfer set forth in the Lockup Agreement are subject to customary exceptions.

Exchange Agreement

On July 11, 2022, the Issuer and certain direct and indirect holders of Issuer Class A ordinary shares and Class B ordinary shares, of the Issuer entered into that certain Exchange Agreement (the “Exchange Agreement”) pursuant to which, subject to the procedures and restrictions therein, from and after the waiver or expiration of any contractual lock-up period (including pursuant to the Lock-Up Agreement) the holders of common units of ProKidney LP, a subsidiary of the Issuer (or certain permitted transferees thereof) will have the right from time to time at and after 180 days following the Closing to exchange their Common Units and an equal number of Class B ordinary shares on a one-for-one basis for Class A ordinary shares (the “Exchange”); provided, that, subject to certain exceptions, ProKidney, at its sole election, subject to certain restrictions, may, other than in the case of certain secondary offerings, instead settle all or a portion of the Exchange in cash based on a volume weighted average price of a Class A ordinary share. The Exchange Agreement provides that, as a general matter, a holder of Common Units will not have the right to exchange Common Units if ProKidney determines that such exchange would be prohibited by law or regulation or would violate other agreements with ProKidney and its subsidiaries to which the holder of Common Units may be subject, including the Second Amended and Restated ProKidney Limited Partnership Agreement (as defined below) and the Exchange Agreement.

Business Combination Agreement

On the Closing Date, SCS consummated the previously announced Business Combination with “ProKidney”. In connection with the closing of the Business Combination, the registrant changed its name from “Social Capital Suvretta Holdings Corp. III” to “ProKidney Corp.”. At Closing, the following transactions occurred:

• (i) ProKidney LP issued to SCS a number of Common Units equal to the number of fully diluted outstanding SCS ordinary shares as of immediately prior to the Closing (but after giving effect to all redemptions of SCS Class A ordinary shares and the purchase of SCS Class A ordinary shares and/or Common Units pursuant to one or more subscription agreements (the “PIPE Placement”)), in exchange for (a) (x) Issuer Class B ordinary shares, which shares would have no economic rights but would entitle the holders thereof to vote on all matters on which shareholders of Issuer would be entitled to vote generally, and (y) restricted stock rights in respect of Issuer Class B ordinary shares (“Issuer Class B PMEL RSRs”), which restricted stock rights would convert into Issuer Class B ordinary shares upon the vesting of the associated PMEL RCUs, (b) an amount in cash equal to the aggregate proceeds obtained by SCS in the PIPE Placement and (c) an amount in cash equal to the aggregate proceeds available for release to SCS from SCS’s trust account (“Trust Account”) (after giving effect to all redemptions of SCS Class A ordinary shares and after payment of any deferred underwriting commissions being held in the Trust Account and payment of certain transaction expenses);

• (ii) Issuer distributed to the Closing Issuer Unitholders the Issuer Class B ordinary shares and Issuer Class B PMEL RSRs received pursuant to clause (i)(a) (x) and (y) above; and

• (iii) holders of old ProKidney LP Class A common units received an aggregate of 17,500,000 Earnout RCUs and 17,500,000 Earnout RSRs (collectively, the “Earnout Rights”), which Earnout Rights would vest in three equal tranches upon the achievement of certain Issuer share price milestones or certain change of control events. When vested, the Earnout RCUs would automatically convert into Common Units and the associated Earnout RSRs would automatically convert into Issuer Class B ordinary shares, respectively.

The foregoing descriptions of the Registration Rights Agreement, Lock-Up Agreement, Exchange Agreement and Business Combination Agreement do not purport to be complete and are qualified in their entirety by reference to the Registration Rights Agreement, Lock-Up Agreement, Exchange Agreement and Business Combination Agreement, which are filed as Exhibit 3, Exhibit 4, Exhibit 5 and Exhibit 6, respectively, and are incorporated by reference herein.
