NMC Health-owned Spanish fertility business Clinica Eugin has attracted 67 bids from several large private equity firms.
The transaction is valued between €350m – €400m (US$413m – US$472m), according to Expansión.
Potential candidates to acquire Clinica Eugin include companies such as CVC, Cinven, Bridgepoint or HIG, as well as KKR or EQT.
Perella Weinberg Partners are advisors.
Alvarez & Marsal were appointed joint administrators of NMC Health in April after US short seller Muddy Waters published a damaging report calling into question the company’s finances and governance.
Since then the hospital operator’s chair, HJ Mark Tompkins, resigned in the same week the company uncovered that its debt had grown to US$6.6bn.
In July, UK hospital group Aspen Healthcare, which NMC acquired from US firm Tenet Healthcare for £10m in 2018, began to look for a new buyer.
