STAT+: Ionis Pharmaceuticals shares plummet after slow rollout of biotech’s triglyceride-lowering drug

By · Via STAT Health · Published by Everything Blog

In short

Investors wiped out over $1 billion of the company's valuation after third-quarter Tryngolza sales reached only $9 million, badly trailing Wall Street's $21 million consensus. In response to the slow commercial uptake, management slashed its full-year sales outlook for the treatment to $50 million, down from an earlier target of $100 million to $110 million. The equity plunged roughly 25% within a few hours of the market open, tumbling from over $39 to under $28. This rapid repricing underscores the immediate financial fallout when commercial rollouts for potential blockbuster drugs stumble.

Ionis Pharmaceuticals lost more than $1 billion in market value on Monday after the company slashed sales projections for a triglyceride-lowering drug the biotech and Wall Street analysts believe is a potential blockbuster.

The firm announced that it expects the drug, Tryngolza, to bring in $50 million in sales by the end of this year, compared to Ionis’ previous forecast of $100 to $110 million. Third quarter sales came in at $9 million, well below Wall Street consensus expectations of $21 million during the quarter.

The stock reaction was swift. Shares that traded at more than $39 when the market opened within hours sank below $28, a drop of around 25%.
