Income Taxes

Note 4: Income Taxes

ProKidney is considered to be an exempted Cayman Islands company and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States.

The Company’s subsidiary, PKLP, is organized as a limited partnership and is classified as a partnership for U.S. income tax purposes, and as such, only records a provision for federal and state income taxes on its subsidiaries organized as C corporations or which have elected to be treated as corporations for U.S. federal income tax purposes.

The Company’s subsidiary, ProKidney-US, is treated as a C corporation, and therefore a provision for federal and state taxes has been recorded. The difference between the Company’s effective tax rates and the U.S. statutory rate of 21% is primarily attributable to PKLP and ProKidney-KY being treated as partnerships for income tax purposes.

The Company’s subsidiary, ProKidney-KY, has been granted, by the Government in Council of the Cayman Islands, tax concessions under an undertaking certificate exempting it from any tax levied on profits, income, gains or appreciations in relation to

its operations or in the nature of estate duty or inheritance tax for a period of twenty years from January 20, 2016. ProKidney-KY elected to be treated as an entity disregarded from its owner for U.S. tax purposes, and as a result, it has not recorded an income tax provision.

As discussed in Note 6, the Company is party to a tax receivable agreement with a related party which provides for the payment by the Company to holders of PKLP prior to the Closing (“Closing ProKidney Unitholders”) of 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax or franchise tax that the Company actually realizes (or, in some circumstances, the Company is deemed to realize) as a result of certain transactions. As no transactions have occurred which would trigger a liability under this agreement, the Company has not recognized any liability related to this agreement as of March 31, 2024.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, available taxes in the carryback periods, projected future taxable income and tax planning strategies in making this assessment.

There were no net unrecognized tax benefits as of March 31, 2024 which, if recognized, would affect our effective tax rate. We expect none of the gross unrecognized tax benefits will decrease within the next year.

There were no significant changes in the Company’s uncertain tax positions during the three months ended March 31, 2024.
