Ironwood Pharmaceuticals (NASDAQ:IRWD) Releases Quarterly Earnings Results

Ironwood Pharmaceuticals (NASDAQ:IRWD) announced its earnings results on Wednesday. The biotechnology company reported ($0.01) earnings per share (EPS) for the quarter, missing the consensus estimate of $0.02 by ($0.03), FiscalAI reports. The company had revenue of $47.71 million for the quarter, compared to the consensus estimate of $86.10 million. Ironwood Pharmaceuticals had a net margin of 8.70% and a negative return on equity of 15.17%.

Here are the key takeaways from Ironwood Pharmaceuticals’ conference call:

• LINZESS delivered $865M in U.S. net sales in 2025 with double-digit prescription demand growth and the company expects U.S. LINZESS net sales of $1.125–$1.175B in 2026 (a >30% YoY increase) driving company guidance of Adjusted EBITDA >$300M.
• The company won an FDA approval (Nov 2025) expanding LINZESS to treat IBS‑C in patients aged 7 and up — the first prescription approval for ages 7–17 — and lowered list price effective Jan 1, 2026 to support access and improve net pricing dynamics.
• Apraglutide will require a confirmatory Phase 3 (STARS‑2) after FDA review of prior PK/dosing, with a 124‑patient, 1:1 randomized design using the same primary endpoint, site activation planned in Q2 2026 and an anticipated NDA pathway before end of 2029; management projects >$700M U.S. peak sales if approved.
• Ironwood says it strengthened its balance sheet in 2025 (reported $138M Adjusted EBITDA and ~ $215M cash at year‑end per CFO), plans to repay 2026 convertible notes at maturity and expects to reduce total debt to ~ $300M by year‑end 2026 (<1x projected 2026 Adjusted EBITDA), enabling further investment in apraglutide.
• Near‑term risks include Q4 2025 net‑price erosion and rebate‑timing volatility (Q4 LINZESS sales fell 27% YoY), legislative Medicare Part D redesign impacts, and the regulatory requirement for a new confirmatory trial for apraglutide, which delays potential approval and adds execution risk.
