Forward-looking Statements This presentation includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. ProKidney’s actual results may differ from its expectations, estimates and projections and consequently, you should not rely on these forward-looking statements as predictions of future events. Words such as “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believes,” “predicts,” “potential,” “continue,” and similar expressions (or the negative versions of such words or expressions) are intended to identify such forward-looking statements. These forward-looking statements include, without limitation, the Company’s expectations with respect to financial results, future performance, development and commercialization of products, if approved, the potential benefits and impact of the Company’s products, if approved, potential regulatory approvals, and the size and potential growth of current or future markets for the Company’s products, if approved. Most of these factors are outside of the Company’s control and are difficult to predict. Factors that may cause such differences include, but are not limited to: the inability to maintain the listing of the Company’s Class A ordinary shares on the Nasdaq; the inability to implement business plans, forecasts, and other expectations or identify and realize additional opportunities, which may be affected by, among other things, competition and the ability of the Company to grow and manage growth profitably and retain its key employees; the risk of downturns and a changing regulatory landscape in the highly competitive biotechnology industry; the inability of the Company to raise financing in the future; the inability of the Company to obtain and maintain regulatory clearance or approval for its products, and any related restrictions and limitations of any cleared or approved product; the inability of the Company to identify, in-license or acquire additional technology; the inability of Company to compete with other companies currently marketing or engaged in the biologics market and in the area of treatment of kidney diseases; the size and growth potential of the markets for the Company’s products, if approved, and its ability to serve those markets, either alone or in partnership with others; the Company’s estimates regarding expenses, future revenue, capital requirements and needs for additional financing; the Company’s financial performance; the Company’s intellectual property rights; uncertainties inherent in cell therapy research and development, including the actual time it takes to initiate and complete clinical studies and the timing and content of decisions made by regulatory authorities; the impact of COVID-19 or geo-political conflict such as the war in Ukraine on the Company’s business; and other risks and uncertainties indicated from time to time in the Company’s filings with the Securities and Exchange Commission. The Company cautions readers that the foregoing list of factors is not exclusive and cautions readers not to place undue reliance upon any forward-looking statements, which speak only as of the date made. The Company does not undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements to reflect any change in its expectations or any change in events, conditions or circumstances on which any such statement is based.

Targeted therapies that share 4 characteristics: These are “game changing” (disease modifying medicines) for the afflicted patients These targeted therapies treat only between 5k to 70k patients (potentially 290k with Vutrisiran) These medicines are extremely expensive – cost per patient of $200k to up to $2m (mean $680k) and many billions to healthcare budgets While expensive and benefitting small numbers of patients, payors have agreed to reimburse them Clinical benefit ranges from strong to marginal, yet drugs expected to reach market penetration rates of between 13% to 30% (mean 20%; >90% for CF).

Early Clinical Success Sponsorship & Team Strong healthcare investors, funding runway to commercialization Candidate kidney therapy seeking to delay/prevent dialysis in CKD Strong balance sheet for transformative opportunity Social Capital, Suvretta Capital, existing PROK investors  — Healthcare investor expertise already in PROK — $597 million received through SCS business combination and concurrent PIPE — Experienced management team and Board Potential benefits to afflicted patients, society, and investors Phase 2 data show potential to improving multiple kidney function — Open-label 007 Phase 2 will provide insight 2Q/3Q 2023 — Phase 3 program underway — RMAT designation from FDA Capital raised supports Phase 3; Cash runway to interim Phase 3 data — Manufacturing in place for Phase 3, phased scale up planned contingent on approval — $130 billion Medicare spend on ESKD/CKD — Strong IP & know-how Investment opportunity Why ProKidney? Financial Strength Total addressable market data for the year ended 2020 is based on certain estimates of management. This information may prove to be inaccurate because of the method by which the underlying data for the estimates was obtained or because this information cannot always be verified with complete certainty due to the limits on the availability and reliability of raw data, the voluntary nature of the data gathering process and other limitations and uncertainties
