8-K: Ironwood Pharmaceuticals Reaffirms LINZESS Sales Guidance, Boosts EBITDA Forecast for 2025

Ironwood Pharmaceuticals reiterates its full-year 2025 LINZESS U.S. net sales guidance of $800-$850 million and total Ironwood revenue of $260-$290 million, while raising its adjusted EBITDA guidance to greater than $105 million.

Summary

• Ironwood Pharmaceuticals has reaffirmed its full-year 2025 guidance for LINZESS U.S. net sales, projecting between $800 million and $850 million.
• The company also maintains its total revenue guidance of $260 million to $290 million for 2025.
• Adjusted EBITDA guidance has been raised to greater than $105 million for the year.
• First quarter 2025 LINZESS U.S. net sales were $138.5 million, a 46% decrease compared to $256.6 million in the first quarter of 2024.
• This decrease is attributed to a change in AbbVie's estimate of gross-to-net rebate reserves, which is expected to impact the quarterly phasing of LINZESS U.S. net sales but not the full-year results.
• Total LINZESS prescription demand in the first quarter of 2025 was 53 million capsules, an 8% increase compared to the first quarter of 2024.
• Ironwood no longer plans to make certain apraglutide commercial launch planning investments and will shift its focus to the confirmatory Phase 3 trial.

Sentiment

Score: 7

Positives

The company is also focusing on the Phase 3 trial for apraglutide.
