On August 6, 2026, Ardelyx issued a press release a reduction in its full-year 2026 IBSRELA revenue guidance and withdrawal of its long-term XPHOZAH revenue guidance. Management attributed the reduction in IBSRELA revenue guidance to significantly increased payer utilization-management processes that restricted patient access to IBSRELA and slowed new-patient starts. Ardelyx attributed the withdrawal of its XPHOZAH revenue guidance due to “evolving market dynamics” and uncertainty regarding future growth projections.
On this news, Ardelyx’s stock price fell $0.87 per share, or 17.86%, to close at $4.00 per share on August 7, 2026.
