(Reuters) -Pfizer ( PFE ) lifted its annual profit forecast on Wednesday, banking on cost cuts and better-than-expected demand for its COVID antiviral treatment and vaccine.

The U.S. drugmaker's shares rose nearly 3% before the bell after the company said it expects adjusted earnings per share of $2.15 to $2.35 in 2024 compared with a prior forecast of $2.05 to $2.25.

Pfizer's ( PFE ) shares have lost 11% of their value so far this year amid growing investor worries over the drugmaker's growth after the pandemic.

Its stock declined more than 40% last year as billions of dollars in COVID vaccine and treatment sales evaporated.

The drugmaker responded with a $43 billion purchase of cancer drugmaker Seagen, a $4 billion cost-cut plan and internal restructuring.

Revenue from Comirnaty continue to perform consistently with its expectations, Pfizer ( PFE ) said. It expects about 90% of vaccine sales to occur in the second half, mostly in the fourth quarter.

Pfizer ( PFE ) expects revenue from its COVID-19 vaccine Comirnaty and anti-viral treatment Paxlovid to be $8 billion in 2024.

The U.S. drugmaker posted an adjusted profit of 82 cents per share, while analysts on average were expecting it to earn 52 cents, according to LSEG data.
