Exhibit 99.1

Ardelyx Reports Third Quarter 2024 Financial Results and Provides Business Update

IBSRELA generates $40.6 million in net product sales revenue; Company expects full year 2024 IBSRELA net sales revenue to be between $145 and $150 million

XPHOZAH generates $51.5 million in net product sales revenue

Company ends Q3 with approximately $190 million in cash, cash equivalents and investments

Conference call scheduled for 4:30 PM Eastern Time


WALTHAM, Mass., October 31, 2024 - Ardelyx, Inc. (Nasdaq: ARDX), a biopharmaceutical company founded with a mission to discover, develop and commercialize innovative, first-in-class medicines that meet significant unmet medical needs, today reported financial results for the third quarter ended September 30, 2024 and provided a business update.

“The continued strong performance of Ardelyx reported during the third quarter demonstrates our ability to execute and deliver on our goals, to focus on serving the patient and to build towards the future,” said Mike Raab, president and chief executive officer of Ardelyx. “IBSRELA continues to deliver consistent quarter-over-quarter growth driven by strong fundamentals: an attractive safety and efficacy profile, expanding awareness among healthcare prescribers, a streamlined path to access and, importantly, positive experiences among treated patients. In addition, the unmet need among dialysis patients for another option to help achieve and maintain target phosphorus levels is clear, demonstrated by the continued strong demand and growth for XPHOZAH. We remain committed to ensuring that this well-tolerated, effective and differentiated medicine remains available to patients, despite CMS’ planned change in Medicare Part D reimbursement in early-January 2025, and we are confident that we have made decisions that will best support our efforts to protect patient access to XPHOZAH. Finally, we continue to thoughtfully strengthen our balance sheet, providing us with capital to invest as we look to expand our business.”

IBSRELA® (tenapanor) records $40.6 million in net product sales revenue in Q3 2024
U.S. net product sales revenue for IBSRELA during the third quarter of 2024 was $40.6 million, showing approximately 15% quarter-over-quarter growth compared to the second quarter of 2024, and significant growth compared to the $22.3 million in net product sales revenue the company reported during the third quarter of 2023. The strong Q3 2024 performance reflects the continued growing demand for IBSRELA, demonstrated by increases in new and refill prescriptions as well as growth in new and repeat writing healthcare providers.

Ardelyx currently expects full-year 2024 U.S. net product sales revenue for IBSRELA to be between $145.0 and $150.0 million.

XPHOZAH® (tenapanor) launch progresses, records $51.5 million net product sales revenue during Q3 2024
A strong XPHOZAH launch continues, with the company reporting $51.5 million in net product sales revenue during the third quarter of 2024, approximately 39% quarter-over-quarter growth compared to the second quarter of 2024. The Q3 2024 performance reinforces the significant unmet need among dialysis patients with hyperphosphatemia.

IMPORTANT SAFETY INFORMATION (IBSRELA)

WARNING: RISK OF SERIOUS DEHYDRATION IN PEDIATRIC PATIENTS
IBSRELA is contraindicated in patients less than 6 years of age; in nonclinical studies in young juvenile rats administration of tenapanor caused deaths presumed to be due to dehydration. Avoid use of IBSRELA in patients 6 years to less than 12 years of age. The safety and effectiveness of IBSRELA have not been established in patients less than 18 years of age.

CONTRAINDICATIONS
•IBSRELA is contraindicated in patients less than 6 years of age due to the risk of serious dehydration.
•IBSRELA is contraindicated in patients with known or suspected mechanical gastrointestinal obstruction.

WARNINGS AND PRECAUTIONS
Risk of Serious Dehydration in Pediatric Patients
•IBSRELA is contraindicated in patients below 6 years of age. The safety and effectiveness of IBSRELA in patients less than 18 years of age have not been established. In young juvenile rats (less than 1 week old; approximate human age equivalent of less than 2 years of age), decreased body weight and deaths occurred, presumed to be due to dehydration, following oral administration of tenapanor. There are no data available in older juvenile rats (human age equivalent 2 years to less than 12 years).
•Avoid the use of IBSRELA in patients 6 years to less than 12 years of age. Although there are no data in older juvenile rats, given the deaths in younger rats and the lack of clinical safety and efficacy data in pediatric patients, avoid the use of IBSRELA in patients 6 years to less than 12 years of age.

Diarrhea
Diarrhea was the most common adverse reaction in two randomized, double-blind, placebo-controlled trials of IBS-C. Severe diarrhea was reported in 2.5% of IBSRELA-treated patients. If severe diarrhea occurs, suspend dosing and rehydrate patient.

MOST COMMON ADVERSE REACTIONS
The most common adverse reactions in IBSRELA-treated patients (incidence ≥2% and greater than placebo) were: diarrhea (16% vs 4% placebo), abdominal distension (3% vs <1%), flatulence (3% vs 1%) and dizziness (2% vs <1%).

INDICATION
IBSRELA (tenapanor) is indicated for the treatment of Irritable Bowel Syndrome with Constipation (IBS-C) in adults.

Please see full Prescribing Information, including Boxed Warning, for additional risk information.

IMPORTANT SAFETY INFORMATION (XPHOZAH)

CONTRAINDICATIONS
XPHOZAH is contraindicated in:
•Pediatric patients under 6 years of age
•Patients with known or suspected mechanical gastrointestinal obstruction

WARNINGS AND PRECAUTIONS
Diarrhea
Patients may experience severe diarrhea. Treatment with XPHOZAH should be discontinued in patients who develop severe diarrhea.



MOST COMMON ADVERSE REACTIONS
Diarrhea, which occurred in 43-53% of patients, was the only adverse reaction reported in at least 5% of XPHOZAH-treated patients with CKD on dialysis across trials. The majority of diarrhea events in the XPHOZAH-treated patients were reported to be mild-to-moderate in severity and resolved over time, or with dose reduction. Diarrhea was typically reported soon after initiation but could occur at any time during treatment with XPHOZAH. Severe diarrhea was reported in 5% of XPHOZAH-treated patients in these trials.

INDICATION
XPHOZAH (tenapanor), 30 mg BID, is indicated to reduce serum phosphorus in adults with chronic kidney disease (CKD) on dialysis as add-on therapy in patients who have an inadequate response to phosphate binders or who are intolerant of any dose of phosphate binder therapy.

For additional safety information, please see full Prescribing Information.
