Analysis
Ironwood reported a stronger third quarter, with total revenue of $133.0 million versus $122.1 million in the third quarter of 2025. The principal contributor was $129.9 million of LINZESS-related collaboration revenue, up 8.6%, while LINZESS U.S. net sales reported by AbbVie rose 3.2% to $324.9 million. Prescription demand grew 4.9% to 63.4 million LINZESS capsules, while the company attributed net-sales growth to demand growth and a low single-digit net-price decline caused by unfavorable gross-to-net rebate reserves.
Profitability improved across reported measures. Total costs and expenses were $39.9 million, below $46.6 million in the prior-year quarter, despite R&D expense increasing to $28.3 million from $22.5 million. GAAP net income was $59.8 million, compared with $40.1 million, and adjusted EBITDA reached a record $97.9 million, compared with $81.8 million. LINZESS commercial margin was 79.8%, compared with 75.9%, and total net profit for the U.S. LINZESS brand collaboration increased 9.8% to $255.9 million.
The nine-month figures show the same operating pattern. Total revenues were $352,587 (in thousands), GAAP net income was $151,902 (in thousands), and adjusted EBITDA was $257,638 (in thousands), compared with $248,442 (in thousands), $26,293 (in thousands), and $127,170 (in thousands), respectively, in the prior-year period. Nine-month LINZESS U.S. net sales were $879,753 (in thousands), exceeding full-year 2025 U.S. net sales according to the company.
Cash generation was substantial in the quarter, with $130.8 million in cash from operations versus $47.6 million a year earlier. Ironwood repaid $60.0 million on its revolving credit facility, leaving a $325.0 million outstanding principal balance and $225.0 million of remaining borrowing capacity. Cash and cash equivalents were $86.4 million at quarter end, compared with $215.5 million at the end of 2025, while accounts receivable were $132.7 million.
Management raised full-year 2026 guidance to $1.20 - $1.25 billion for LINZESS U.S. net sales, $485 - $510 million for total revenue, and greater than $350 million for adjusted EBITDA. The development focus remains the ongoing STARS-2 confirmatory Phase 3 trial of apraglutide. Ironwood stated that planned activation of more than 100 sites in 22 countries is on track and that it plans to file for regulatory approval in 2029, subject to trial results.
Management, verbatim
Ironwood delivered a third consecutive strong quarter as we continue focused execution of our three strategic priorities: maximize LINZESS, advance apraglutide and deliver sustained profits and cash flows. We believe LINZESS is on its way to returning to blockbuster status for 2026 with year-to-date U.S. net sales already surpassing total 2025 U.S. net sales, primarily driven by improved net price and mid-single-digit prescription demand growth. This gives us confidence to increase full-year 2026 financial guidance for the second consecutive quarter.
Tom McCourt, Chief Executive Officer
In addition to driving strong financial performance, we are ramping up the STARS-2 confirmatory Phase 3 trial of apraglutide in people living with short bowel syndrome with intestinal failure. As we continue to add trial sites in the U.S., all of the planned clinical trial applications have been submitted to international health authorities and are now under review or already approved. Our current focus is on activating sites as quickly as possible to accelerate the trial as we work toward the goal of bringing apraglutide to patients.
