ARDX Class Action Reminder - Robbins LLP Reminds Investors of the Lead Plaintiff Deadline in the Ardelyx, Inc. Securities Class Action Lawsuit

Robbins LLP reminds investors of the November 16, 2026 lead plaintiff deadline in a securities class action against Ardelyx, Inc. (ARDX). The lawsuit alleges the company misled investors about commercial performance and growth prospects for its drugs ISBRELA and XPHOZAH, concealing material adverse facts about payer access barriers and reimbursement challenges. On August 6, 2026, Ardelyx reduced its 2026 IBSRELA revenue guidance and withdrew long-term XPHOZAH guidance, causing the stock to drop 18% in one day from $4.87 to $4.00 per share.
