This agreement implies a valuation of Euro 2,251 million for Auna TLC (including Euro 237 million in debt), subject to any price adjustments typical of this type of operation resulting from variations in net debt and working capital. The agreement is still pending the approval of Auna's Board of Directors, and has to be passed at the shareholder's meeting. The management bodies of the other parties and anti-trust authorities also have to give their go ahead. This operation comes on top of the transaction announced several days ago by which Auna's shareholders will sell Auna's mobile telephony business (Amena) to France Telecom.
