ASTELLAS PHARMA CO. LIMITED
ASTELLAS PHARMA CO. LIMITED is a Private limited company (Ltd.) registered in Ireland under IE397235, and its current status with Companies Registration Office (CRO) is active. The company was incorporated on 3 February 2005 and lists its registered address as Mulhuddart, Ireland. 1 shareholder is on record for ASTELLAS PHARMA CO. LIMITED, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn.
