Exhibit 99.1

Ardelyx Reports Second Quarter 2024 Financial Results and Provides Business Update

IBSRELA generates $35.4 million in net product sales revenue

XPHOZAH generates $37.1 million in net product sales revenue

Company ends Q2 with approximately $186 million in cash and investments

Conference call scheduled for 4:30 PM Eastern Time


WALTHAM, Mass., August 1, 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 second quarter ended June 30, 2024 and provided a business update.

“In the second quarter, Ardelyx demonstrated our commitment to our mission and to ensuring that patients remain at the forefront of all of our efforts. We continued to drive expanded awareness and use of our two first-in-class medicines that represent new therapeutic options for patients who continue to have significant unmet medical needs. In addition, importantly, we are standing with the entire kidney community and fighting for patients whose health is at risk,” said Mike Raab, president and chief executive officer of Ardelyx.

Raab continued, “IBSRELA’s strong performance continued with consistent quarter-over-quarter gains. This performance further strengthens our conviction that IBSRELA is on track to achieve at least ten percent market share and $1 billion in annual sales before patent expiry. IBSRELA is providing meaningful clinical benefits to patients at a time when the need among IBS-C patients to address their symptoms remains significant. We believe IBSRELA is well placed to address this unmet need and we continue to invest, including the ongoing expansion of our sales team to further our growth trajectory. XPHOZAH’s remarkable performance continued, a clear indicator of the need for a novel therapy, like XPHOZAH, to help patients achieve target phosphorus levels. This is why it is so important that we take steps to protect patients against the dire consequences of the access restrictions that will occur if CMS moves oral-only phosphate lowering therapies into the End-Stage Renal Disease Prospective Payment System.”

IBSRELA® (tenapanor) records $35.4 million in net product sales revenue in Q2 2024
U.S. net product sales revenue for IBSRELA during the second quarter of 2024 was $35.4 million, showing approximately 25% quarter-over-quarter growth compared to the first quarter of 2024, and significant growth compared to the second quarter of 2023. The strong performance reflects the meaningful demand for IBSRELA, demonstrated by continued increases in new and refill prescriptions as well as growth in new and repeat writing healthcare providers.

Ardelyx continues to expect full-year 2024 U.S. net product sales revenue for IBSRELA to be between $140.0 and $150.0 million.

XPHOZAH® (tenapanor) launch progresses, records $37.1 million net product sales revenue during Q2 2024
Ardelyx continued to see a strong response to XPHOZAH from the nephrology community. U.S. net product sales revenue during Q2 2024 was $37.1 million, demonstrating significant quarter-over-quarter growth compared to the $15.2 million in net product sales revenue reported during the first quarter of 2024.

During the quarter, the company announced that an analysis of the Centers for Medicaid and Medicare Services (CMS) End-Stage Renal Disease Prospective Payment System (ESRD PPS) proposed rule to include oral-only medicines in the ESRD PPS revealed that the policy and the manner in which CMS intends to implement it are likely to cause significant restrictions on the use of XPHOZAH for all patients, irrespective of insurance coverage, because it interferes with the essential and appropriate shared decision-making between healthcare professionals and their patients. As part of an effort to protect patient access to XPHOZAH, the company announced on July 2 that it has chosen not to apply for the ESRD PPS Transitional Drug Add-on Payment Adjustment; and on July 18, the company announced that it has filed a lawsuit against CMS in partnership with the American Association of Kidney Patients and the National Minority Quality Forum claiming that CMS has violated its statutory and regulatory authority in its determination to include oral-only phosphate lowering therapies in the ESRD PPS.

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.
