Eli Lilly stock tumbles 10% after drug giant misses estimates and slashes profit guidance

Eli Lilly on Wednesday fell short of profit and revenue expectations for the third quarter and slashed its full-year adjusted profit guidance, sending its stock tumbling roughly 10%.

The pharmaceutical giant's blockbuster weight loss drug Zepbound and diabetes treatment Mounjaro posted weaker-than-expected sales, which the company attributed to inventory decreases in the wholesale channel.

The drugmaker now expects full-year adjusted earnings of between $13.02 to $13.52 per share, down from previous guidance of $16.10 to $16.60 per share. Eli Lilly pointed to a $2.8 billion acquisition-related charge that it recorded during the third quarter as denting its results.

Eli Lilly also lowered the high-end of its revenue outlook for the year and now expects sales of between $45.4 billion and $46 billion. The company's previous guidance called for revenue of as much as $46.6 billion.

Here's what Eli Lilly reported for the period ended September 30 compared with what Wall Street was expecting, based on a survey of analysts by LSEG: 

The company recorded third-quarter net income of $970.3 million, or $1.07 per share, compared with a net loss of $57.4 million, or 6 cents per share, during the third quarter of 2023.

Excluding one-time items associated with the value of intangible assets and other adjustments, Eli Lilly posted earnings of $1.18 per share for the most recent quarter.

The company posted third-quarter revenue of $11.44 billion, up 20% from the same period a year ago.

Demand in the U.S. has far outpaced supply for Lilly's incretin drugs, such as Zepbound and Mounjaro, over the last year. Both treatments mimic certain gut hormones to tamp down a person's appetite and regulate their blood sugar.

The popularity of those injectable drugs has forced both Eli Lilly and its main rival, Novo Nordisk, to invest billions to increase manufacturing capacity for the treatments.

Eli Lilly's supply woes began to ease earlier this year. As of Wednesday, the Food and Drug Administration's drug database said all doses of Zepbound and Mounjaro are available in the U.S. after extended shortages. Still, the agency warns that patients may not always be able to immediately fill their prescription for those drugs at a particular pharmacy.
