In September 2018, after receiving regulatory approval, Advent International acquired Zentiva, Sanofi's European generics business via parent company AI Sirona (Luxembourg) Acquisition Sarl, for an enterprise value of €1.92 billion. Zentiva benefits from well-entrenched market positions in major European markets, supported by a very diverse product portfolio, highly competitive costs of manufacturing, and a track record of winning tenders. We are assigning our 'B' issuer credit rating to AI Sirona. The stable outlook on Zentiva reflects our view that, in the next 12-18 months, the company will continue to benefit from its well-balanced presence in its European markets, supporting volume, revenue, and EBITDA growth. We expect Zentiva will maintain our adjusted debt to EBITDA between 6.0x and 7.0x on average
