NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

1. Description of Transaction

On July 11, 2022, SCS and Legacy ProKidney consummated the Business Combination contemplated by the Business Combination Agreement.

Following the Closing, the combined company was organized in an umbrella partnership-C corporation (or “Up-C”) structure, and the combined company’s direct assets consisted of Post-Combination ProKidney Common Units and all of the issued and outstanding equity interests of GP, which replaced Legacy GP as the general partner of Legacy ProKidney upon the Closing, and substantially all of the operating assets and business of the combined company is held indirectly through Legacy ProKidney, as described further below. ProKidney is domiciled in the Cayman Islands.

Pursuant to the Business Combination Agreement, the following transactions occurred:

• prior to the Closing: (i) Legacy ProKidney amended and restated the ProKidney Limited Partnership Agreement to be in the form of the Second Amended and Restated ProKidney Limited Partnership Agreement, which became effective upon the completion of the Business Combination; (ii) GP amended and restated its constitution, which became effective upon the completion of the Business Combination; (iii) SCS amended and restated the Memorandum and Articles of Association to be in the form of the Second Amended and Restated Memorandum and Articles of Association, which became effective upon the completion of the Business Combination; (iv) (A) each issued and outstanding Legacy ProKidney Class B Unit that was not vested pursuant to the terms of the applicable award agreement with the applicable holder as of such time was recapitalized into one PMEL RCU, which would, when vested in accordance with the applicable award agreement, automatically convert into a Post-Combination ProKidney Common Unit (and the associated Legacy ProKidney Class B PMEL RSR would vest) and (B) all other issued and outstanding Legacy ProKidney Class A Units and ProKidney Class B Units were recapitalized into an aggregate number of Post-Combination ProKidney Common Units equal to (x) 175,000,000 minus (y) the number of PMEL RCUs issued pursuant to the foregoing clause (A); (v) Legacy ProKidney completed a restructuring of PMEL; and (vi) Legacy ProKidney issued 5,000,000 Post-Combination ProKidney Common Units pursuant to certain Subscription Agreements in connection with the exercise of election by certain holders to purchase Post-Combination ProKidney Common Units in lieu of SCS Class A ordinary shares; and

• at the Closing: (i) Legacy ProKidney issued to SCS a number of Post-Combination ProKidney 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 Post-Combination ProKidney Common Units pursuant to the PIPE Investment), in exchange for (a) (x) ProKidney Class B ordinary shares, which shares have no economic rights but entitle the holders thereof to vote on all matters on which shareholders of the combined company are entitled to vote generally, and (y) ProKidney Class B PMEL RSRs, which shall convert into ProKidney Class B ordinary shares upon the vesting of the associated PMEL RCUs (as described above), (b) an amount in cash equal to the aggregate proceeds obtained by SCS in the PIPE Investment and (c) an amount in cash equal to the aggregate proceeds available for release to SCS from the 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) Legacy GP resigned as the general partner of Legacy ProKidney and GP was be admitted as the general partner of Legacy ProKidney; (iii) Legacy ProKidney distributed to the Closing ProKidney Unitholders the ProKidney Class B ordinary shares and ProKidney Class B PMEL RSRs received pursuant to clause (i)(a) (x) and (y) above; and (iv) the Earnout Participants received the Earnout Rights, which Earnout Rights will vest in three equal tranches upon the achievement of certain ProKidney share price milestones or certain change of control events. When vested, the Earnout RCUs will automatically convert into Post-Combination ProKidney Common Units and the associated Earnout RSRs will automatically convert into ProKidney Class B ordinary shares, respectively.

Pursuant to the Exchange Agreement as described elsewhere in this prospectus, each Post-Combination ProKidney Common Unit, together with one Class B ordinary share, is generally exchangeable for one Class A ordinary share, subject to certain procedures and restrictions.

Basis of Presentation and Accounting Policies

The unaudited pro forma condensed combined financial information has been adjusted to include transaction accounting adjustments related to the Business Combination in accordance with GAAP.

We determined that the Business Combination qualified as a common control transaction and, therefore, was accounted for akin to a reverse recapitalization, with no goodwill or other intangible assets recorded, in accordance with GAAP. Legacy ProKidney is considered the accounting acquirer primarily based on the evaluation of the following facts and circumstances:

Under the guidance in ASC 805 for transactions between entities under common control, the assets, liabilities, and noncontrolling interests of Legacy ProKidney and SCS were recognized at their carrying amounts on the date of the Business Combination. Under this method of accounting, SCS was treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Legacy ProKidney issuing stock for the net assets of SCS, accompanied by a recapitalization. The net assets of SCS were stated at their historical value within the pro formas with no goodwill or other intangible assets recorded.

• The individual controlling Legacy ProKidney prior to the Business Combination also controls the combined company as a result of the Voting Agreement, which provides Tolerantia with the majority of the votes related to the appointment and removal of the majority of the Board;

• The Legacy ProKidney unitholders prior to the Closing comprise a majority of the voting power of the combined company following the Closing;

• Senior management of Legacy ProKidney prior to the Closing comprise the senior management of the combined company following the Closing; and

• The operations of Legacy ProKidney prior to the Closing comprise the ongoing operations of the combined company following the Closing.

Upon completion of the Business Combination, GP became the sole general partner of Legacy ProKidney. Giving effect to the redemption of 22,829,769 Class A ordinary shares, ProKidney has the sole voting interest in Legacy ProKidney through its ownership of GP. As a result, ProKidney consolidated the financial results of Legacy ProKidney and reports a non controlling interest related to the Post-Combination ProKidney Units held by Legacy ProKidney’s investors prior to the Closing on ProKidney’s consolidated balance sheet. The computation of the non controlling interest following the Closing, is as follows:

	Units		Percentage
Interest in ProKidney LP held by the Issuer		61,540,231		25.5	%
Noncontrolling interest in the Issuer		180,000,000		74.5	%
Total		241,540,231		100.0	%

Proposed Accounting Treatment of the Earnout Rights

As discussed in this Note 1, the Earnout Participants received 17,500,000 Earnout Rights upon Closing. Upon satisfaction, during the five-year period after the Closing, of certain volume weighted average price (“VWAP”) thresholds, or a change in control with a per share price exceeding the VWAP thresholds within a five-year period immediately following the Closing, the Earnout Rights will automatically vest and convert into Post-Combination ProKidney Common Units and ProKidney Class B ordinary shares. As the Business Combination was accounted for as a reverse recapitalization, the issuance of the Earnout Rights to the Legacy ProKidney unitholders was accounted for as an equity transaction. Since the Earnout Rights were payable to the Legacy ProKidney unitholders (i.e., the accounting acquirer in the business combination), the accounting for the Earnout Rights arrangement did not fall under Accounting Standards Codification (“ASC”) Topic 805, Business Combinations nor Topic 718, Stock Compensation.

The accounting for the Earnout Rights was also evaluated under ASC Topic 480, Distinguishing Liabilities from Equity, to determine if the arrangement should be classified as a liability. As part of that preliminary analysis, it was determined that the Earnout Rights did not meet the criteria to be accounted for as a liability. Additionally, the Earnout Rights were evaluated under ASC Topic 815, Derivatives. As part of that preliminary analysis, it was determined that the Earnout Rights met the definition of a derivative; however, they meet the scope exception criteria as they were clearly and closely related to the entity’s own stock, and met the criteria for equity treatment. Therefore, an adjustment to recognize the Earnout Rights would have no net impact on any financial statement line item as it would simultaneously increase and decrease additional paid-in capital. Thus, no adjustment has been applied to the unaudited pro forma combined financial information related to the Earnout Rights.

2. Adjustments to Unaudited Pro Forma Condensed Combined Financial Information

The unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X. The adjustments in the unaudited pro forma condensed combined financial information have been identified and presented to provide relevant information necessary for an illustrative understanding of the combined company upon consummation of the Business Combination in accordance with GAAP.

The unaudited pro forma condensed combined financial information has been presented for illustrative purposes only and is not necessarily indicative of the operating results and financial position that would have been achieved had the Business Combination occurred on the dates indicated. The unaudited pro forma condensed combined financial information does not purport to project the future operating results or financial position of ProKidney following the completion of the Business Combination. The unaudited pro forma adjustments represent management’s estimates based on information available as of the date of this unaudited pro forma condensed combined financial information and are subject to change as additional information becomes available and analyses are performed. SCS and Legacy ProKidney did not have any historical relationship prior to the transactions. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

The unaudited pro forma condensed combined financial statements give effect to the redemption of 22,829,769 Class A ordinary shares.

3. Transaction Adjustments

Adjustments to Unaudited Pro Forma Condensed Combined Balance Sheet as of March 31, 2022

(2) Reflects the payment of $7.7 million of underwriters’ fees deferred by SCS and which were paid at the Closing.

(3) Reflects the gross proceeds of $574.8 million from the issuance and sale of 57.5 million ProKidney Class A ordinary shares at $10.00 per share pursuant to the Subscription Agreements entered into with PIPE Investors in connection with the PIPE Investment.

(5) Represents transaction costs of $37.3 million incurred by Legacy ProKidney prior to, or concurrent with, the Closing that were cash settled upon Closing in accordance with the Business Combination Agreement. Of that amount, approximately $17.5 million related to investment transaction fees; $11.9 million related to equity financing fees associated with the PIPE Investment, and the remaining $7.9 million related to direct and incremental costs such as legal, tax, accounting, third-party advisory and other miscellaneous fees. This amount excluded the $7.7 million of deferred underwriting fees related to the SCS initial public offering as described in note (2) above, any amounts relating to the ProKidney Promissory Notes, which were repaid at the Closing, and other SCS transaction costs.

(6) Represents repayment of amounts drawn on ProKidney Promissory Notes.

(7) Repayment of related party advance.

(b) Reflects the liquidation and reclassification of investments held in the Trust Account to cash and cash equivalents.

The combined company does not expect to record net deferred tax assets related to the tax basis adjustments associated with the exchange of Paired Interests as those deferred tax assets are not more likely than not expected to be realized in accordance with ASC 740—Income Taxes. Accordingly, the combined company has not recorded a liability related to the Tax Receivable Agreement as of December 31, 2021, as the liability is not considered to be probable in accordance with ASC 450—Contingencies.

(h) Reflects the reclassification of SCS Class A ordinary shares, giving effect to the redemption of 22,829,769 SCS Class A ordinary shares.

Adjusted additional paid in capital				$	131,531

(m) Represents transaction costs of $37.3 million incurred by Legacy ProKidney prior to, or concurrent with, the Closing that were cash settled upon Closing in accordance with the Business Combination Agreement. Of that amount, approximately $17.5 million related to investment transaction fees; $11.9 million related to equity financing fees associated with the PIPE financing and the remaining $7.9 million related to direct and incremental costs such as legal, tax, accounting, third-party advisory and other miscellaneous fees. This amount excluded the $7.7 million of deferred underwriting fees related to the SCS initial public offering as described in note (2) above, any amounts relating to the ProKidney Promissory Notes, which were repaid at the Closing, and other SCS transaction costs.

(n) Represents the issuance of 17,500,000 Earnout Rights to Earnout Participants upon Closing. As discussed in Note 2 to the unaudited condensed consolidated financial statements, the adjustment to recognize the Earnout Rights would have no net impact on any financial statement line item as it would simultaneously increase and decrease additional paid-in capital.

(o) Represents the exchange of SCS Class A ordinary shares, SCS Class B ordinary shares and related director restricted stock units held by the Sponsor and an independent director of SCS for ProKidney Class A ordinary shares.

Adjustments to Unaudited Pro Forma Condensed Combined Statement of Operations for the Three Months Ended March 31, 2022

(aa) Represents the adjustment to eliminate interest income related to the investment held in Trust Account.

(bb) Does not reflect a pro forma adjustment to income tax expense as Legacy ProKidney has historically been in a net loss position. Legacy ProKidney files as a partnership for federal and state income tax purposes. As such, each partner is responsible for reporting income or loss to the extent required by federal and state income tax regulations, based upon their respective share of Legacy ProKidney income and expenses. ProKidney-US is a limited liability company and has elected to be treated as a C corporation, therefore, a provision for federal and state taxes has been recorded. Income tax expense of the combined company may differ from historical results due to the change in structure of ProKidney.

(cc) Represents the adjustment for the net loss attributable to noncontrolling interest. The noncontrolling interest, giving effect to redemptions, is 74.5%.

(dd) Represents the loss per share calculated using the historical weighted average shares outstanding, and the issuance of additional shares in connection with the Business Combination, assuming the shares were outstanding since January 1, 2021. As the Business Combination and related equity transactions are being reflected as if they had occurred at the beginning of the period presented, the calculation of weighted average shares outstanding for basic and diluted net income per share assumes that the shares issuable relating to the Business Combination were outstanding for the entirety of the period presented.

(m) Upon the completion of the Business Combination, the combined company became a party to the Tax Receivable Agreement.

certain circumstances as a result of certain tax attributes that exist following the Transaction and that are created thereafter, including as a result of payments made under the Tax Receivable Agreement. The combined company does not expect to record net deferred tax assets related to the tax basis adjustments associated with the exchange of Paired Interests as those deferred tax assets are not more likely than not expected to be realized in accordance with ASC 740—Income Taxes. Accordingly, the combined company has not recorded a liability related to the Tax Receivable Agreement as of December 31, 2021, as the liability is not considered to be probable in accordance with ASC 450—Contingencies.
