[2] As of 2024, Acadia operated over 50 inpatient psychiatric hospitals in 19 U.S. states, including Arizona, Arkansas, Florida, Georgia, Indiana, Michigan, Missouri, New Mexico, Ohio, Oklahoma, Pennsylvania, Tennessee, Utah, and Wisconsin.

[14] In 2014, Acadia entered the methadone-clinic business when it bought CRC Health, a large-addiction treatment chain, from the private equity firm Bain Capital.

[8][15] Acadia rapidly expanded this business, and by late 2024, it operated 165 methadone clinic in 33 states, making it the U.S.'s largest methadone-clinic chain.

[17] In 2019, Acadia paid $17 million to resolve the allegations made by federal prosecutors in West Virginia that the comopany had overbilled Medicaid for blood and urine tests.

[19] In January 2024, the Utah Department of Health and Human Services ordered Midvale's Highland Ridge Hospital to hire an independent monitor for ten hours a week to oversee safety compliance.

[4][24][25] The committees' report stated the problems "occur inevitably and by design: they are the direct causal result of a business model that has the incentive to treat children as payouts and provide less than adequate safety and behavioral health treatment in order to maximize operating and profit margin".

[3] In September 2024, Acadia agreed to pay $19.84 million to settle the U.S. Securities and Exchange Commission (SEC)'s allegations of numerous legal violations, including a false billing for medically unnecessary inpatient services.
