Anthony Conway, PhD, ProKidney’s Head of Research and Development, will review key findings from the Company’s ASN presentations and discuss how they contribute to the understanding of rilparencel’s multifactorial mechanism of action.

These forward-looking statements include, without limitation, the achievement and timing of the topline data readout of the Company’s PROACT 1 trial and other milestones provided, the Company’s beliefs that its Phase 3 REGEN-006 (PROACT 1) trial could be sufficient to support a potential BLA submission and full regulatory approval, that eGFR slope can be used as a surrogate endpoint on an accelerated approval pathway for rilparencel, expectations with respect to financial results and expected cash runway, including the Company’s expectation that current cash will support operating plans into mid-2027, future performance, development and commercialization of products, if approved, the potential benefits and impact of the Company’s products, if approved, potential regulatory approvals, the size and potential growth of current or future markets for the Company’s products, if approved, the advancement of the Company’s development programs into and through the clinic and the expected timing for reporting data, the making of regulatory filings or achieving other milestones related to the Company’s product candidates, and the advancement and funding of the Company’s developmental programs, generally.
