Pediatrix Medical Group's stock experienced a significant pre-market plunge of 6.19% on Thursday.

The sharp decline follows the company's release of its fourth-quarter financial results, which revealed a miss on key analyst estimates. Pediatrix reported adjusted earnings per share of $0.50, falling short of the consensus estimate of $0.54. Furthermore, the company's adjusted EBITDA of $65.845 million came in below the estimated $71.1 million.

While quarterly revenue of $493.771 million surpassed expectations, it represented a year-over-year decrease. The earnings disappointment appears to be the primary driver behind the negative investor sentiment in the pre-market session.
