Operating Highlights
LINZESS U.S. net sales: Achieved $865 million in 2025, with 11% demand growth and 8% new-to-brand volume growth year-over-year. FDA approved LINZESS for IBS-C treatment in patients aged 7-17, making it the first prescription drug for this age group.
Apraglutide: Met with FDA to align on Phase III trial design (STARS-2) for short bowel syndrome. Trial to begin in Q2 2026. Apraglutide has shown strong efficacy and tolerability, with potential U.S. peak net sales of over $700 million.
LINZESS market share: Maintained prescription market leadership for IBS-C and chronic constipation in the U.S., with a 45% market share and over 5.7 million unique patients treated since launch.
Apraglutide market potential: Expected to redefine standard of care for short bowel syndrome, with potential approvals abroad further increasing market opportunity.
Financial performance: Delivered $138 million in adjusted EBITDA and ended 2025 with $250 million in cash and cash equivalents. Disciplined expense management resulted in $127 million in cash flows from operations.
Debt reduction: Plans to reduce total debt balance in 2026, including repayment of 2026 convertible notes, aiming for less than 1x adjusted EBITDA by year-end.
2026 priorities: Focus on maximizing LINZESS, advancing apraglutide, and disciplined expense management to deliver profits and strengthen financial position.

Risk or Challenges
LINZESS Price Reduction: The decision to lower the LINZESS list price effective January 1, 2026, in response to evolving healthcare dynamics could impact revenue generation and profitability, especially if the price reduction does not lead to a proportional increase in demand.
Regulatory Requirements for Apraglutide: The FDA's request for a confirmatory Phase III trial (STARS-2) for apraglutide due to issues in the prior trial's dose preparation and administration introduces delays and additional costs, potentially impacting the timeline for NDA submission and commercialization.
Dependence on LINZESS for Revenue: LINZESS remains a key revenue driver, and any unforeseen market dynamics, such as increased competition or changes in payer access, could adversely affect financial performance.
Debt Obligations: The company plans to repay its 2026 convertible notes at maturity in June, which could strain cash reserves if cash flows do not meet expectations.
Economic and Legislative Changes: The Medicare Part D redesign and other legislative changes have already impacted LINZESS net sales in 2025, and further regulatory or economic shifts could pose additional challenges.
Clinical Trial Risks for Apraglutide: The success of the STARS-2 trial is critical for the approval and commercialization of apraglutide. Any setbacks in trial execution or results could delay or jeopardize its market entry.

Guidance & Outlook
LINZESS U.S. Net Sales: Expected to exceed $1.1 billion in 2026, driven by improved net price and low single-digit prescription demand growth.
Adjusted EBITDA: Projected to be greater than $300 million in 2026, supported by increased LINZESS sales and disciplined expense management.
Apraglutide Development: Phase III confirmatory trial (STARS-2) to begin site activation in Q2 2026, with an NDA submission anticipated before the end of 2029. Apraglutide has the potential to achieve over $700 million in U.S. peak net sales, with additional opportunities in international markets.

Key Q&A
Q:Can you give us details on the learnings from STARS and the refined options for use in STARS-2?
A:The original STARS trial was successful in terms of the primary endpoint and patient benefits. The main learnings were about dose and administration, leading to improved dosing accuracy and better instructions for use in STARS-2.
Q:Where are you and the FDA aligned on using the same primary and key secondary endpoints?
A:The FDA appreciated the endpoints in the original STARS trial, so STARS-2 uses the same primary and key secondary endpoints. This similarity gives confidence in the outcome of STARS-2.
Q:What is the enrollment timeline and criteria for STARS-2?
A:The team has learned from the original STARS program and has many sites ready from the STARS Extend program. They are confident in enrolling the program on time but acknowledge it will require significant effort.
Q:Can you update us on your thinking regarding the strategic alternatives process?
A:The company is in a better financial position now and has a clear path forward leveraging increased revenue from LINZESS and reducing debt. They remain open to alternatives that increase shareholder value but are focused on strong execution.
Q:What assumptions are being made for the STARS-2 enrollment timeline compared to STARS-1?
A:The assumptions are based on the execution of STARS-1, which was successful. The team believes they can achieve similar results for STARS-2, considering the trial's high probability of success and attractive design for patients.
Q:What are your thoughts on LINZESS as it approaches the negotiated price year in 2027?
A:The company is optimistic about LINZESS's future and its ability to drive strong net sales and profits. They have not provided specific guidance for 2027 but expect continued growth.
Q:How much of your existing clinical data is the FDA allowing you to reference for a future NDA for STARS-2?
A:The company plans to leverage the original STARS data as much as possible, as the dose in STARS-2 aligns with the original trial. The FDA will review this decision during the NDA submission.
Q:Why is the planned enrollment size for STARS-2 higher than competitors?
A:The sample size of 124 patients was decided to ensure robust power for primary and secondary endpoints. This decision was made to achieve confidence in the trial's outcome.
Q:Could you add a higher dose arm to maximize efficacy differentiation in STARS-2?
A:The company is focused on getting to market quickly with the current dose but continues to evaluate the opportunity for higher doses to increase response breadth.
Q:Did patients who achieved the optimum dose in STARS benefit more than others?
A:The original STARS trial showed robust efficacy with placebo-like tolerability. The optimum dose was determined to be 3.5 mg, which is being used in STARS-2. There is biomarker evidence suggesting potential benefits of higher doses, but the focus is on confirming the current dose.
Q:What is the market opportunity for apraglutide given potential competition from GATTEX generics?
A:The company believes apraglutide has a differentiated profile and can achieve market leadership even with competition. They expect peak U.S. net sales of over $700 million, assuming competition from generics and other therapies.
Q:What channel mix effects drove the LINZESS rebate in Q4, and should we expect ongoing pricing volatility?
A:The Q4 pricing was impacted by timing of gross-to-net rebate reserves, not channel mix. The company expects less volatility in 2026 compared to 2025.
Q:What is the formulary positioning for LINZESS in 2026 compared to the prior year?
A:The company has maintained broad patient access for LINZESS across commercial and Medicare Part D. They anticipate low single-digit demand volume growth and have adjusted pricing to ensure access.
Q:Why did LINZESS commercial volume fall at the beginning of the year?
A:The decline is attributed to seasonality due to high-deductible plans resetting in Q1. This pattern has been consistent over the years, and the company expects growth to accelerate throughout the year.
Q:Review of Unclear Management Responses
A:Management avoided providing specific guidance for LINZESS in 2027, citing optimism but lacking detailed projections. They also did not provide a formal update on the strategic alternatives process, using vague language about being open to shareholder value opportunities.
