Shares of Pfizer and German partner BioNTech fell today after the US drugmaker slashed the sales forecast for its Covid vaccine and therapy last week, and some analysts said the reduction was bigger than expectations.
Hit by a plunge in the use of pandemic-related products, Pfizer on Friday reduced its full-year forecast for sales of its antiviral Covid treatment Paxlovid by about $7 billion.
It also cut the outlook for the vaccine it developed with BioNTech by about $2 billion.
Pfizer said it will take a non-cash charge of $5.5 billion in the third quarter due to $4.6 billion in inventory write-offs for Paxlovid and $900m of write-offs for the vaccine, while BioNTech flagged write-downs of up to €900m ($947m).
The Covid sales forecast cut was bigger than expected, Wells Fargo analyst Mohit Bansal said, adding that Wall Street's Covid sales estimates for the next few years may come down.
Shares in BioNTech, which is also developing cancer treatments, were down 6.7% to hit a two-month low in Frankfurt. Its US-listed shares fell 5% in premarket trading, while Pfizer's shares fell 3.5%.
The news also dragged down shares of rival Covid vaccine maker Moderna by 3.8%.
BioNTech, which relies on vaccine-related profit-sharing payments from Pfizer for much of its revenue, said the write-offs would also reduce its 2023 revenue.
A BioNTech spokesperson today declined to comment on the company's current 2023 outlook.
The company added that it had been told by Pfizer that most of the write-offs relate to raw materials, as well as to inventories of vaccine versions that are older or different from the upgraded one currently in use.
