Red flags

  • MS product revenue fell $310.9 million, or 7.1%, in 2025, while TECFIDERA faces multiple generic entrants and TYSABRI faces biosimilar competition.
  • Diluted EPS fell 21.4% year over year despite 2.2% total-revenue growth, indicating material earnings pressure beneath the modest top-line increase.
  • Certain SKYCLARYS starting materials rely on a single supplier based in China, creating tariff, geopolitical and continuity exposure.
  • TYSABRI carries royalties of 18.0% of annual worldwide net sales up to $2.0 billion and 25.0% above that level; SPINRAZA and QALSODY royalties are 11.0%-15.0%, and VUMERITY royalties are 15.0%-16.0%.
  • Biogen issued $1.75 billion of senior notes in 2025, including debt carrying coupons of 5.050%-6.450%, increasing interest burden while the portfolio is transitioning.
