Acadia Healthcare Company, Inc. (NASDAQ: ACHC), a leading provider of behavioral healthcare services, experienced a significant 10.61% plunge in its stock price during the after-hours trading session on Thursday. This drastic decline followed the release of the company's fourth-quarter 2024 financial results and full-year 2025 guidance, which failed to meet analysts' expectations.

In the fourth quarter, Acadia reported revenue of $774.2 million, missing the consensus estimate of $779 million. The company's adjusted EBITDA of $153.1 million also fell short of the expected $171.4 million, despite posting a net income of $33.5 million for the quarter.

Looking ahead, Acadia provided a disappointing outlook for the full year 2025. The company forecasted revenue in the range of $3.3 billion to $3.4 billion and adjusted EBITDA between $675 million and $725 million. Additionally, Acadia anticipated capital expenditures ranging from $525 million to $575 million as it continues to invest in expanding its psychiatric bed capacity to meet the growing demand for mental health services.

The lackluster performance and tepid guidance suggest that Acadia is facing challenges in achieving the expected growth trajectory. Despite the company's efforts to expand its facilities and services, it appears to be struggling to translate these investments into immediate financial gains, falling short of Wall Street's expectations.
