BioArctic AB (publ) (BRCTF)

How it makes money

Almost all revenue is royalties: a percentage of what Eisai sells of Leqembi worldwide, paid without BioArctic bearing any of the development, regulatory or marketing costs — but also without it controlling how fast Eisai ramps up sales in each country. A second stream comes from research collaborations such as the Novartis BrainTransporter deal, which brought an upfront payment and offers further milestones and royalties only if Novartis later licenses a resulting drug candidate.

BioArctic's value rests on patents covering lecanemab and on its proprietary BrainTransporter technology for getting therapies across the blood-brain barrier, which it has now licensed twice, most recently to Novartis. That intellectual property is defensible but narrow: it covers specific molecules and one delivery platform, not a broad or repeatable advantage across the whole neurodegeneration field.

Demand for an approved Alzheimer's treatment is driven by diagnosis rates, physician adoption and reimbursement decisions in each country rather than by the broader economy, so it does not move with economic cycles. It does move with Eisai's pace of launching Leqembi market by market, which BioArctic does not control.

Key risks

• Dependence on Eisai's commercialization — Under the 2007 agreement, Eisai alone is responsible for clinical development, regulatory approval and worldwide sales of lecanemab; BioArctic's royalty income rises or falls with decisions and execution it does not control, and Eisai has already revised its own Leqembi sales projections.
• Revenue concentrated in a single approved product — Leqembi royalties remain the large majority of BioArctic's revenue today; the Novartis and other partnerships are still at the research or milestone stage and have not yet produced a second marketed product to diversify that dependence.
• Competition in neurodegenerative disease research — Large pharmaceutical companies with far bigger research budgets, including Pfizer, Novartis and Roche, are also developing treatments for Alzheimer's and related conditions, and could bring forward therapies that compete with Leqembi or with BioArctic's earlier-stage pipeline.
