Shares of West Pharmaceutical Services (WST) soared 12% on Thursday afternoon after the company increased its full-year earnings guidance after its third-quarter earnings beat Wall Street expectations.

The Pennsylvania-headquartered company, which manufactures packaging components and delivery systems for injectable drugs and healthcare products, raised its full-year net sales guidance to $3.06 billion to $3.07 billion, up from $3.04 billion to $3.06 billion.

It also hiked its full-year adjusted earnings per share (EPS) outlook to $7.06 to $7.11, up from $6.65 to $6.85, citing strong demand for its high-value product (HVP) components used in GLP-1 drugs for weight loss and diabetes regulation. In Q3, HVP components accounted for 48% of the company's total net sales.

The firm, however, flagged that it continues to anticipate $15 million to $20 million in tariff-related costs this year.

CEO Remarks

Chief Executive Eric M. Green stated that several factors drove HVP component sales in Q3. “First, elastomers for GLP-1s had strong growth and now account for 9% of total company sales. We benefit from our longstanding relationships as we partner with our customers in this market, supporting them as they expand their GLP-1 franchises…We expect this market to continue to evolve as there are a number of new early-stage trials seeking to expand the range of indications and treatments using GLP-1s,” Green said.

He added that the company, which includes weight-loss drugmakers Eli Lilly and Novo Nordisk among its customers, is also collaborating with customers who are launching new GLP-1 molecules and generics.

Third Quarter Earnings

For the third quarter (Q3), West Pharmaceutical reported adjusted and diluted EPS of $1.96, compared to $1.85 in the same period last year, and above an analyst estimate of $1.68, according to data from Fiscal AI. Net sales increased 7.7% year-over-year to $804.6 million in the quarter.

The company reported a 16.3% increase in net sales of its HVP components to $390 million in the quarter. Contract-manufactured products segment net sales, meanwhile, rose 8% to $157.1 million, driven by increased sales of self-injection devices for obesity and diabetes.

Evercore ISI analyst Daniel Markowitz raised the firm's price target on West Pharmaceutical to $390 from $350 while keeping an ‘Outperform’ rating on the shares following the earnings call.
