What this means for investors
Pfizer cut its 2025 revenue guidance from to $62 billion, down from between $61 billion and $64 billion. It reaffirmed its 2025 adjusted EPS of $3.00 - $3.15.
It told investors it is expecting flat growth for 2026, with anticipated revenues between $59.5 billion and $62.5 billion. This is down to falling revenue from COVID drugs and expiring patents.
The company said it is cutting costs and investing the proceeds into R&D. For example, it recently acquired a biopharmaceutical company focused on obesity and cardiometabolic diseases. It will push ahead with obesity drug trials in 2026. However, it could take time for newer initiatives to bear fruit.
