Dear Investor,

We appreciate your interest in ProKidney, and today I’m writing to share that ProKidney will become a publicly traded company via a business combination with Social Capital Suvretta Holdings Corp. III (“SCS”) (Nasdaq: DNAC), a special purpose acquisition company (SPAC). Upon close, the transaction will allow ProKidney to build upon our success to date and continue our work to change the lives of the tens of millions of patients with chronic kidney disease (“CKD”) through our first-of-its-kind disease-modifying autologous cellular therapy. You can read more about today’s announcement in our press release [here – insert link].

This transaction will provide ProKidney with up to $825 million to fund REACT^®’s Phase 3 development program, accelerate our manufacturing buildout, and be even better capitalized as we prepare for REACT^®’s anticipated global commercial launch in late 2025 to mid-2026. With promising early results from clinical trials, REACT^® has the potential to not only slow the progression of CKD, but in some cases drive meaningful improvement in kidney function: a potential game-changer in CKD therapies. As a public company, we will have more efficient access to additional capital and expanded resources.

For background, SCS is a partnership between leading investment firm Social Capital (led by Chamath Palihapitiya) and Suvretta Capital (led by Kishen Mehta and David Friedman). SCS was created to partner with innovative, agile biotech companies like ProKidney to help them realize their full potential at critical business junctures. Importantly, we are taking this step with SCS because they are the perfect partner for us at such a key inflection point in our company’s trajectory, with the launch this month of our Phase 3 clinical trial.

We anticipate this transaction will close in the third quarter of 2022, following approval by SCS’s shareholders and other customary closing requirements.

We will continue to provide updates on our progress as appropriate and, in the meantime, if you have any questions, please do not hesitate to reach out.

Best regards,
