Centrul Medical Unirea (CMU), the medical services business Advent International bought from 3i earlier this year, has acquired privately owned Romanian hospital group Euroclinic Medical Centers.Euroclinic operates one of the largest private hospitals in Romania and runs three medical centres. Led by chief executive Wargha Enayati, the company has 325 employees and generated revenues of €8m last year.Advent’s bolt-on of Euroclinic combines a hospital operation with CMU’s ambulance and corporate healthcare services.CMU provides ambulatory and inpatient medical services through a network of 19 clinics. It also operates a maternity hospital and a surgery unit.“Advent International has successfully implemented buy-and-build strategies across the Central and Eastern European region. Healthcare is one of the core sectors in which Advent has built considerable expertise, and it is one of our key strategies to pursue consolidation plays across the Central and Eastern European healthcare sector,” said Emma Popa-Radu, managing director at Advent.Advent took an 80 per cent stake in CMU in February this year, with 3i relinquishing a nearly 49 per cent stake after investing in the healthcare company in 2007. When 3i entered the business three years ago alongside 3TS Capital Partners, it was touted as the largest transaction to involve a Romanian healthcare provider.Bolt-on acquisitions currently represent 20 per cent of aggregate global private equity deal volume and six per cent of total deal value, according to recent data released by research provider Preqin.
