Company snapshot

Acadia Healthcare provides behavioral healthcare services through inpatient psychiatric hospitals, specialty treatment facilities, residential treatment centers, and outpatient clinics.
The firm serves individuals in need of behavioral health treatment in the United States and Puerto Rico, targeting both adults and adolescents.

Acadia Healthcare runs a broad network of behavioral health facilities, serving patients across the U.S. and Puerto Rico. It is a leading provider of behavioral healthcare services, operating a large network of facilities focused on mental health and addiction treatment. The company leverages its scale and specialized care delivery to address a broad spectrum of behavioral health needs across diverse patient populations.

What this transaction means for investors

Capital tends to flee when confidence erodes faster than fundamentals can stabilize. A 60% one-year drop will do that, especially in healthcare, where reimbursement risk and regulatory scrutiny never really go away.

Acadia is not a shrinking business on paper. Late last month, the company reaffirmed 2025 guidance calling for revenue between $3.28 billion and $3.30 billion, adjusted EBITDA of $601 million to $611 million, and adjusted EPS of $1.94 to $2.04. It operates 278 facilities with roughly 12,500 beds across 40 states and Puerto Rico—scale that matters in behavioral health, where demand remains structurally strong.

But leadership turnover adds another layer of uncertainty. Debbie Osteen has stepped back in as CEO as the board evaluates paths to enhance shareholder value. At the same time, Medicaid financing changes under the OBBBA and broader macro pressures hang over providers. Within the broader portfolio, the remaining 0.6% weight is small compared with larger allocations to diversified industrial and services names. That shift suggests capital is rotating toward steadier cash generators.
