Revvity Inc. (RVTY) shares plummeted 5.47% in pre-market trading on Monday, despite reporting better-than-expected second-quarter results. The sharp decline comes as the company lowered its full-year profit forecast, overshadowing its strong quarterly performance.

For the second quarter, Revvity posted adjusted earnings per share of $1.18, surpassing the FactSet estimate of $1.14. Revenue for the quarter came in at $720.3 million, also beating analysts' expectations of $710.4 million. The company's adjusted EBIT of $191.802 million also exceeded the estimated $187.2 million.

However, investors seemed to focus on Revvity's revised full-year guidance. The company now expects adjusted EPS for fiscal 2025 to be between $4.85 and $4.95, down from its previous projection of $4.90 to $5.00. While Revvity slightly raised the lower end of its revenue forecast to $2.84 billion-$2.88 billion from $2.83 billion-$2.87 billion, the reduced earnings outlook appears to have spooked investors, leading to the significant pre-market sell-off.
