Shares of biopharma company Ardelyx, Inc. (ARDX) edged up about 0.5% in after-hours trading on Thursday after closing lower during the regular session as investors processed its quarterly earnings and drug sales projections.

Ardelyx swung to a fourth-quarter (Q4) net income of $0.02 per diluted share from a loss of $0.12 a year earlier, surpassing analyst expectations of breakeven.

Ibsrela, its treatment for irritable bowel syndrome with constipation, generated $53.8 million in Q4 net product sales revenue, reflecting about 32% growth from Q3. 

Full-year 2024 sales reached $158.3 million, and the company expects U.S. net product sales for 2025 to range between $240 million and $250 million.

In 2024, Xphozah's first full year of commercialization saw U.S. sales hit $160.9 million. The company estimates that peak annual U.S. sales will reach $750 million before its patent expires.
