NEW YORK, Oct. 2, 2026 /PRNewswire/ — Why: Rosen Law Firm, a global investor rights law firm, reminds purchasers of common stock of Ardelyx, Inc. (NASDAQ: ARDX) between January 13, 2025 and August 6, 2026, inclusive (the “Class Period”), of the important November 16, 2026 lead plaintiff deadline.
So what: If you purchased Ardelyx common stock during the Class Period you may be entitled to compensation without payment of any out of pocket fees or costs through a contingency fee arrangement.
What to do next: To join the Ardelyx class action, go to https://rosenlegal.com/cases/ardelyx-inc-2026/join or call Phillip Kim, Esq. toll-free at 866-767-3653 or email case@rosenlegal.com for information on the class action. A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than November 16, 2026. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.
Why Rosen Law: We encourage investors to select qualified counsel with a track record of success in leadership roles. Often, firms issuing notices do not have comparable experience, resources, or any meaningful peer recognition. Many of these firms do not actually handle securities class actions, but are merely middlemen that refer clients or partner with law firms that actually litigate the cases. Be wise in selecting counsel. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm has achieved the largest ever securities class action settlement against a Chinese Company. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 4 each year since 2013 and has recovered billions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020, founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs’ Bar. Many of the firm’s attorneys have been recognized by Lawdragon and Super Lawyers.
Details of the case: According to the complaint, defendants provided overwhelmingly positive statements to investors while, at the same time, disseminating materially false and misleading statements and/or concealing material facts concerning the true state of Ardelyx’s commercial performance and growth prospects for XPHOZAH and IBSRELA, and in particular the increasing payer-related access and reimbursement barriers affecting patient access, more stringent prior authorization requirements and step edit requirements that slowed new-patient starts and delayed prescription fulfillment. When the true details entered the market, the lawsuit claims that investors suffered damages.

No Class Has Been Certified. Until a class is certified, you are not represented by counsel unless you retain one. You may select counsel of your choice. You may also remain an absent class member and do nothing at this point. An investor’s ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.
