Acadia Healthcare (ACHC) saw its stock price plummet 8.61% in after-hours trading on Wednesday, following the company's announcement of revised financial guidance for the fiscal year and unexpected legal charges.

The behavioral healthcare services provider lowered its full-year adjusted earnings per share (EPS) guidance to a range of $2.35 to $2.45, signaling potential challenges in its financial performance. While the company maintained its revenue outlook at $3,280-$3,300 million for the fiscal year, the reduced EPS forecast suggests pressure on profitability.

Adding to investor concerns, Acadia disclosed an incremental assumption on legal charges ranging from $4.0 million to $6.0 million, now expected in the fourth quarter. This unexpected development likely contributed to the sharp sell-off, as it represents an additional financial burden and potential operational headwinds for the company.
