Bar width shows how precise the guidance is — a pin is a stated date, a wide band a six-month window. Deeper blue means more of the thesis rides on the event; it is not a view on the stock.

Verdict history (5 calls)
Every verdict Biotech Distilled has published on Ardelyx, oldest first — the full history, never a selection. How calls are scored: the track record.
- 2026-07-01 Watch Ardelyx (ARDX) — Scientific Deep Dive for IBSRELA, XPHOZAH, and the Tenapanor Pipeline IBSRELA is a real growing franchise but the 2033 composition-of-matter cliff, CMS-impaired XPHOZAH, thin pipeline, and absence of specialist conviction capital cap terminal value below a Buy.
- 2026-07-02 Watch UPDATE: Ardelyx (ARDX) - $50M Debt Draw, No Dilution Debt draw extends runway to 2030 without dilution but does not change the 2033 patent cliff or XPHOZAH bundle headwinds; watch list maintained.
- 2026-08-07 Avoid UPDATE: Ardelyx (ARDX) - The Guidance Cut Nobody Priced IBSRELA guidance cut ~15% and $1B target date removed in a single quarter, XPHOZAH peak guidance withdrawn, and payer headwinds confirmed as structural — the thesis ceiling stopped being theoretical.
- 2026-08-17 Avoid UPDATE: Ardelyx (ARDX) - The Commercial Chief Walks CCO resignation 11 days after the guidance cut leaves the payer-access counteroffensive leaderless at the worst possible moment, reinforcing the structural nature of the headwind.
- 2026-11-04 Avoid UPDATE: Ardelyx (ARDX) - Half the Test, Passed GTN improved to 31.7% meeting one of two stated conditions, but no CCO successor named and new securities litigation filed; both conditions must be met before upgrading.
