Patent expiration and generic competition for LABA products - Relvar/Breo faces potential generic entry in late 2020s depending on patent litigation outcomes, which would materially reduce royalty revenue
Shift toward biologic therapies in respiratory markets - newer treatments like Dupixent (IL-4/IL-13 inhibitors) for severe asthma could erode market share for traditional LABA/ICS combinations
Healthcare pricing pressure and formulary restrictions - increasing scrutiny on branded drug pricing could lead to unfavorable formulary positioning or mandatory rebates that reduce net sales underlying royalty calculations
GSK commercial execution risk - company is entirely dependent on GSK's sales force effectiveness, marketing investments, and strategic prioritization of respiratory franchise versus other therapeutic areas
Competitive launches in COPD/asthma space - AstraZeneca (Symbicort, Breztri), Boehringer Ingelheim, and others with differentiated mechanisms could capture market share from GSK products
Inability to source accretive royalty acquisitions - with $200M annual free cash flow and limited organic growth opportunities, failure to deploy capital into high-return royalty purchases would pressure valuation multiples
Concentration risk in GSK royalty stream - 85-90% revenue dependence on single partner creates binary risk if GSK relationship deteriorates or products underperform
Limited financial risk given strong balance sheet metrics, but aggressive buyback programs could reduce financial flexibility if royalty revenues decline unexpectedly
