By Mill Chart
Last update: Aug 4, 2025
Ardelyx Inc (NASDAQ:ARDX) reported its second-quarter 2025 financial results, delivering revenue and earnings per share (EPS) figures that surpassed analyst expectations. The company’s performance, coupled with strong commercial execution, has triggered a notable market reaction, with shares rising sharply in after-hours trading.
Earnings and Revenue Beat Estimates
- Reported Revenue: $97.7 million, up 33% year-over-year, exceeding the consensus estimate of $82.7 million.
- Reported EPS: -$0.08, better than the estimated -$0.1362.
- Key Drivers:
- IBSRELA (tenapanor) generated $65.0 million in net sales, reinforcing its position as a leading treatment for irritable bowel syndrome with constipation (IBS-C).
- XPHOZAH (tenapanor) contributed $25.0 million, demonstrating growing adoption in chronic kidney disease (CKD) patients on dialysis.
The revenue beat was primarily driven by strong demand for both commercial products, with IBSRELA continuing to dominate sales. The narrower-than-expected loss suggests improved operational efficiency, even as the company continues to invest in commercialization efforts.
