Biogen Inc. (BIIB) Q4 2025 Earnings Call Transcript

Biogen tops Q4 earnings and sales estimates, and shares rise after the company issues an encouraging 2026 adjusted EPS outlook despite revenue pressure.

The headline numbers for Biogen (BIIB) give insight into how the company performed in the quarter ended December 2025, but it may be worthwhile to compare some of its key metrics to Wall Street estimates and the year-ago actuals.

Biogen swung to a loss as results were hurt by a double-digit decline in revenue from its core multiple sclerosis treatments.

Biogen Inc. (BIIB) came out with quarterly earnings of $1.99 per share, beating the Zacks Consensus Estimate of $1.61 per share. This compares to earnings of $3.44 per share a year ago.

Biogen says it expects revenue to fall in 2026 as its multiple sclerosis therapies continue to struggle.

Biogen forecast 2026 profit above Wall Street estimates on Friday, banking on demand for newer medicines and its Alzheimer's treatment Leqembi as older multiple sclerosis drugs battle pressure from cheaper versions.

CAMBRIDGE, Mass., Feb. 04, 2026 (GLOBE NEWSWIRE) -- Biogen Inc. (Nasdaq: BIIB) today announced that Nature Medicine published results from the Phase 2/3 DEVOTE study evaluating the high-dose regimen of nusinersen, comprised of 50 mg/5 mL loading and 28 mg/5 mL maintenance doses, in spinal muscular atrophy (SMA). The high-dose regimen of nusinersen offers a more rapid loading regimen, two 50 mg doses 14 days apart, and a higher maintenance regimen, 28 mg, every 4 months, compared to the 12 mg nusinersen regimen (SPINRAZA®). The results showed the safety and effectiveness of the high-dose regimen of nusinersen across a broad range of people living with SMA, irrespective of age, prior treatment experience, and baseline functional status.

It's been an interesting start to the year, with plenty of geopolitical developments for investors to unpack.

Biogen heads into Q4 earnings with MS drug pressure, while Leqembi and Skyclarys' growth could help offset declines ahead of its Feb. 6 report.
