Ardelyx Inc (NASDAQ:ARDX) Surges 11.6% After Q2 2025 Earnings and Revenue Beat Estimates

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.

Market Reaction

Following the earnings release, Ardelyx shares surged 11.6% in after-hours trading, reflecting investor optimism around the company’s growth trajectory. The stock had been relatively flat over the past month (+1.4%) and week (+0.9%), but the earnings beat appears to have reignited bullish sentiment.

Analyst Estimates vs. Outlook

While the press release did not provide explicit forward guidance, analysts currently project:

• Q3 2025 Revenue Estimate: $96.6 million
• Q3 2025 EPS Estimate: -$0.0839
• Full-Year 2025 Revenue Estimate: $367.3 million
• Full-Year 2025 EPS Estimate: -$0.4113
