Biogen (BIIB) earnings Q4 2023

Biogen on Tuesday reported fourth-quarter revenue and profit that shrank from a year ago, as it recorded charges related to dropping its controversial Alzheimer’s drug Aduhelm and as sales slumped in its multiple sclerosis therapies, the company’s biggest drug category.

Biogen booked sales of $2.39 billion for the quarter, down 6% from the same period a year ago. It reported net income of $249.7 million, or $1.71 per share, for the fourth quarter, down from net income of $550.4 million, or $3.79 per share, for the same period a year ago. Adjusting for one-time items, the company reported $2.95 per share.

The drugmaker’s fourth-quarter earnings per share, both unadjusted and adjusted, saw a negative impact of 35 cents associated with previously disclosed costs of pulling Aduhelm, which had a polarizing approval and rollout in the U.S.

Biogen is cutting costs while pinning its hopes on its other Alzheimer’s drugs, including its closely watched treatment Leqembi, and other newly launched products to replace declining revenue from its multiple sclerosis therapies.

Shares of Biogen fell nearly 7% in early morning Tuesday.

Here’s what Biogen reported for the fourth quarter compared with what Wall Street was expecting, based on a survey of analysts by LSEG, formerly known as Refinitiv: 

• Earnings per share: $2.95 adjusted vs. $3.18 expected
• Revenue: $2.39 billion vs. $2.47 billion expected

Also on Tuesday, Biogen issued full-year 2024 guidance that calls for adjusted earnings of $15 to $16 per share. Analysts surveyed by LSEG had expected full-year earnings guidance of $15.65 per share.

The drugmaker said it expects 2024 sales to decline by a low to mid-single digit percentage compared with last year. But the company anticipates its pharmaceutical revenue, which includes product revenue and its 50% share of Leqembi sales, to be flat this year compared with 2023.
