NMC Health stood by its forecasts for 2019 and 2020 and announced a share buyback on Wednesday NMC Health Plc said on Monday it had launched an independent review of its books, less than a week after US short-selling firm Muddy Waters criticized the health care group’s financials, triggering a major selloff in its shares. The UAE-based firm said the third-party review would be undertaken by an accounting firm and would be overseen by a committee consisting of independent non-executive directors of NMC. Muddy Waters last week questioned the value of NMC’s assets and cash balance as well as its reported profits and debts in a research note.
