Forward-looking Statements Some of the statements included in this presentation, particularly those regarding the commercialization and ongoing clinical development of Auryxia, our updated 2017 financial guidance and the submission of an sNDA to the FDA to expand the label of ferric citrate to include the treatment of IDA in adults with stage 3-5 NDD-CKD and the potential approval in this indication and the impact thereof on Keryx, may be forward-looking statements that involve a number of risks and uncertainties. For those statements, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. Among the factors that could cause our actual results to differ materially are the following: whether we can increase adoption of Auryxia in patients with CKD on dialysis in order to achieve our 2017 financial guidance; whether we can maintain our operating expenses to projected levels while continuing our current clinical, regulatory and commercial activities; the risk that the FDA may not concur with our interpretation of our Phase 3 study results in NDD- CKD, supportive data, conduct of the studies, or any other part of our regulatory submission and could ultimately deny approval of ferric citrate for the treatment of IDA in adults with stage 3-5 NDD-CKD; the risk that if approved for use in NDD-CKD that we may not be able to successfully market Auryxia for use in this indication; our ability to continue to supply Auryxia to the market; and other risk factors identified from time to time in our reports filed with the Securities and Exchange Commission. Any forward looking statements set forth in this presentation speak only as of the date on the first slide. We do not undertake to update any of these forward looking statements to reflect events or circumstances that occur after the date hereof.

Closing Remarks Greg Madison President and Chief Executive Officer

Key Takeaways Strong second quarter 2017 growth supports $62 to $66 million in full year 2017 net U.S. Auryxia product sales guidance Large unmet need in iron deficiency anemia; preparing for potential launch of Auryxia for second indication, pending approval in November 2017 Second indication would provide operational efficiencies by leveraging existing field based infrastructure, access and familiarity established with Auryxia Building foundation to achieve vision of a multi-product renal company Auryxia is currently indicated for the control of serum phosphorus levels in CKD patients on dialysis; Ferric citrate is being evaluated for use in non-dialysis dependent CKD patients as a treatment for iron deficiency anemia.
