Why Did Vertex Pharmaceuticals Stock Fall On Tuesday?

On Monday, Vertex Pharmaceuticals Incorporated (NASDAQ:VRTX) reported lower-than-expected first-quarter 2025 earnings.

Vertex reported first-quarter adjusted earnings per share of $4.06, down from $4.76 a year ago, missing the consensus of $4.32.

The cystic fibrosis-focused company reported sales of $2.77 billion, missing the consensus of $2.85 billion.

Total revenue increased by 3%, primarily driven by the continued performance of Trikafta/Kaftrio and an early contribution from the U.S. launch of Alyftrek.

  • In the U.S., total revenue increased 9% to $1.66 billion due to continued strong patient demand and higher net realized pricing.
  • Outside the U.S., total revenue decreased 5% to $1.11 billion, as strong patient demand in established and newer markets was offset by the expected revenue decline in Russia, where Vertex is experiencing a violation of its intellectual property rights.

Guidance: Vertex raised the low end of total revenue guidance by $100 million to $11.85 billion-$12 billion from $11.75 billion-$12 billion, compared to the consensus of $11.97 billion.

The guidance also includes an immaterial cost impact from tariffs in 2025 based on currently known tariff rates and regulations.

Vertex has temporarily paused the multiple ascending dose portion of the Phase 1/2 study of VX-522, a nebulized CFTR mRNA therapy, to assess a tolerability issue.

William Blair writes, “While the pause is unfortunate, we believe that the decision to pause the study rather than discontinue it suggests that, beyond the tolerability issue, management is encouraged by the data generated to date given it is open-label.”

Analyst reactions:

  • Leerink Partners downgrades Vertex from Outperform to Market Perform and lowers the price target from $550 to $503.
  • Needham reiterates Vertex Pharmaceuticals from Hold to Hold.
  • JP Morgan maintains Vertex with an Overweight rating, raising the price target from $512 to $515.

Price Action: VRTX stock closed lower by 9.91% at $450.61 on Tuesday.
