Radiation Therapy Services Holdings’ wholly-owned subsidiary Radiation Therapy Services International has acquired Medical Developers (MDLLC), a developer and operator of cancer treatment facilities in Latin America for $80m.

The total purchase price consists $47.5m in cash, $16.25m in senior subordinated notes and $16.25m in equity of affiliates of Radiation Therapy.

The cash portion was financed through the issuance of $50m of additional senior subordinated notes.

Under the terms of the agreement, Radiation Therapy purchased an additional 72% of the business resulting in a 91% ownership interest in the Latin American entities.

MDLLC generated revenues of $53.1m and pro forma adjusted EBITDA of $17.5m in 2010, with respective growth rates of 28% and 36%.

Radiation Therapy Services president and CEO Daniel Dosoretz said Medical Developers represents a great fit for Radiation Therapy from both a strategic and financial perspective.

"With 29 centers in six Latin American countries, MDLLC serves to drive continued growth while also providing geographic and payer diversification," Dosoretz said.
