III or “SCS”) (Nasdaq: PROK) (the “Company”), a leading late clinical-stage cellular therapeutics company focused on chronic kidney disease (CKD), today announced financial results of ProKidney LP (“ProKidney”) and its subsidiaries for the second quarter ended June 30, 2022 and provided an update on recent corporate developments. “During the first half of 2022, we continued to execute on our clinical and operational plan, positioning us well to achieve our near- and longer-term strategic objectives,” said Tim Bertram, Ph.D., Chief Executive Officer of ProKidney. “The funding received through the completion of SCS’ business combination with ProKidney in July will support the execution of our Phase 3 program evaluating REACT™ as a potential treatment for the millions of individuals who suffer from chronic kidney disease. I am extremely proud of all that our team has accomplished to date and look forward to the opportunities that lie ahead.” Recent Business Highlights ProKidney completed its previously announced business combination with SCS and commenced trading of the combined company’s Class A ordinary shares on the Nasdaq Capital Market under the ticker symbol “PROK.” As a result of the business combination, ProKidney received gross proceeds of $596.5 million, before transaction fees and related costs, which the Company believes will be sufficient to fund operations through data from its ongoing Phase 3 registrational program for REACT™ targeting diabetic CKD. All other financial and operating results in this release are for the business of ProKidney and its subsidiaries and do not give effect to the closing of the business combination, which occurred on July 11, 2022 (after the close of the quarter ended June 30, 2022).We continue to enroll subjects in the U.S. Phase 3 study (REGEN-006) to assess the efficacy of up to two REACT™ injections, given three months apart, and delivered once into each kidney.Expanded target enrollment for REGEN-007 from 30 subjects to up to 50 subjects. REGEN-007 is an ongoing, prospective, randomized, open-label, repeat dose, double-arm, controlled safety and efficacy study of REACT™ in subjects with type 1 or 2 diabetes and CKD, in which one injection of REACT™ will occur in each kidney.Our highly experienced leadership team was expanded and strengthened through the recruitment of highly qualified personnel to support operations. Recent additions to the ProKidney team include Todd Girolamo, Chief Legal Officer and Corporate Secretary, Dr. Libbie McKenzie, Chief Medical Officer and Dr. Kerry Cooper, Senior Vice President of Medical Affairs.

Second Quarter Financial Highlights of ProKidney LP and its Subsidiaries Cash Position: Cash and cash equivalents as of June 30, 2022, was $21.9 million compared to $20.6 million at December 31, 2021. In connection with the close of the business combination on July 11, 2022, ProKidney received gross proceeds of $596.5 million. These proceeds were used to repay $35.0 million of related party notes and $50.4 million of expenses previously incurred by SCS and fees incurred in connection with the PIPE placement. R&D Expenses: Research and development expenses were $11.6 million for the three months ended June 30, 2022, compared to $11.0 million for the same period in 2021. The increase of $0.6 million was driven by a $1.3 million increase in costs associated with equity-based compensation related to awards granted during 2022. Further, cash-based compensation costs increased by $1.1 million, driven primarily by the hiring of additional personnel. Other research and development costs related to professional fees, quality control, manufacturing improvements and depreciation have also increased by approximately $1.9 million. These costs were offset by decreases in clinical trial costs of approximately $3.9 million, related primarily to decreased costs for the Phase 3 trials which were incurring start-up costs during the three-month period ended June 30, 2021. G&A Expenses: General and administrative expenses were $9.2 million and $1.7 million for the three months ended June 30, 2022 and 2021, respectively. The increase of $7.5 million was primarily driven by a $6.5 million increase in equity-based compensation. Additionally, there was a $0.7 million increase in cash-based compensation expense which was driven by the hiring of additional personnel. Income Tax Expense: Income tax expense was $1.2 million for the three months ended June 30, 2022, compared with a de minimis amount for the three months ended June 30, 2021. The increase in income tax expense was driven primarily by the impact of a provision of the Tax Cuts and Jobs Act of 2017 (the “TCJA”) which became effective for tax years beginning after December 31, 2021. This provision requires specified research and development expenses to be capitalized and amortized ratably over a five-year period and is the primary driver of the income tax expense recognized during the three months ended June 30, 2022. Net Loss per Share: Diluted net loss per share was $(0.12) based on 186,500,000 Class A Units outstanding for the three months ended June 30, 2022. Diluted net loss per share for the three months ended June 30, 2021 was $(0.09) based on 140,109,890 Class A Units outstanding. About ProKidney ProKidney, a pioneer in the treatment of CKD through innovations in cellular therapy, was founded in 2015 after a decade of research. ProKidney’s lead product candidate, REACT™ (Renal Autologous Cell Therapy), is a first-of-its-kind, patented, autologous cellular therapy with the potential to not only slow and stabilize the progression of CKD, but in some cases possibly drive meaningful improvement in kidney function. Late-stage CKD, Stage 3b – 4, is a key target for REACT™ therapy. REACT™ has received Regenerative Medicine Advanced Therapy (RMAT) designation, as well as FDA and EMA guidance, supporting its ongoing Phase 3 clinical program, which launched in January 2022.

CKD is a serious diagnosis with significant morbidity and mortality, notable for the 5-year mortality of a new diagnosis of CKD Stage 4 being higher than that of a new non-metastatic cancer diagnosis. CKD most often presents as a progressive decline in kidney function ultimately resulting in the failure of the kidneys and the need for renal replacement therapy, such as hemodialysis, or kidney transplant. One in three Americans is at risk for CKD which currently affects approximately 75 million people in the United States and Europe and over 400 million across Asia. CKD is among the largest single expenses incurred by the US Health care system.
