INSM: European Bronchiectasis Launch Will Drive Future Respiratory Platform Upside

Insmed's analyst price target has been lifted by about $8 to roughly $215, as analysts factor in strong Brinsupri momentum, expanding indications, and solid execution across the broader respiratory pipeline.

Analyst Commentary

Bullish analysts continue to lift their models as Brinsupri's early momentum and label breadth in non cystic fibrosis bronchiectasis reshape expectations for Insmed's long term revenue trajectory and margin expansion.

The collective updates highlight a growing conviction that the company is transitioning from a single product story into a broader respiratory growth platform, with multiple value drivers beyond the initial launch.

Bullish Takeaways

• Bullish analysts are embedding additional Brinsupri indications into their forecasts, arguing that the expanded opportunity in non cystic fibrosis bronchiectasis is still underappreciated in current valuation multiples.
• Formal EC approval and anticipated early 2026 access, including a planned German launch, are viewed as key catalysts that could accelerate ex US revenue and support higher long term peak sales assumptions.
• Recent quarters of commercial outperformance across two existing products, along with early deployment of a dedicated Brinsupri sales force, are cited as evidence of strong execution that lowers launch risk and supports premium growth ratings.
• Pipeline progress, including encouraging Phase 2 data for TPIP in pulmonary arterial hypertension and growing confidence in Treprostinil Palmitil Inhalation Powder, underpins the thesis that Insmed can evolve into a diversified respiratory franchise with multiple shots on goal.

Bearish Takeaways

• More cautious analysts point to ongoing uncertainty around market access and reimbursement for Brinsupri, noting that price and formulary negotiations could delay the full realization of modeled revenues.
• There are concerns that physician education and awareness, while improving, may take longer than expected to translate into broad adoption, creating potential volatility versus near term sales expectations.
• Some models flag execution risk around simultaneous global launches and late stage pipeline development, warning that any setback in regulatory timelines or study readouts could compress valuation premia.
• Despite the recent re rating, a subset of investors is seen as sensitive to high expectations embedded in elevated price targets, leaving shares vulnerable to pullbacks if quarterly results or launch metrics fall short of the increasingly bullish outlook.

What's in the News

• Truist raised its Insmed price target to $214 from $139, citing stronger than expected performance from the company's two commercial products and growing confidence that Brinsupri access concerns will ease as physician awareness builds (Truist research note).
• The European Commission approved BRINSUPRI (brensocatib 25 mg) as the first and only therapy for non cystic fibrosis bronchiectasis in eligible patients across the EU, following accelerated assessment based on Phase 3 ASPEN and Phase 2 WILLOW data.
• Insmed raised its 2025 global ARIKAYCE revenue guidance to $420 million to $430 million, which now implies 15% to 18% year over year growth versus 2024.
• The company announced that its Phase 2b BiRCh study of brensocatib in chronic rhinosinusitis without nasal polyps failed to meet primary and secondary endpoints. As a result, Insmed will discontinue this indication while advancing Phase 2 programs for INS1148 in interstitial lung disease and moderate to severe asthma.

Valuation Changes

• Fair Value: reduced modestly from $222.78 to $214.78, reflecting slightly more conservative long term assumptions.
