The firm was co-owned by Universal Molasses Corporation (UNIMOLCO), and a consortium led by three businessmen (collectively known themselves as the "BAN Group") who were cronies of the Marcoses: Jose L. Africa, Manuel H. Nieto Jr., and Roberto Benedicto.

[5] In 2005, the Philippine government, thru its national privatization program, sold its 57% stake in ETPI to businessman and former Trade Minister of the Marcos administration Roberto Ongpin through ISM Communications Corporation.

SMC later bought the remaining stake thru another subsidiary (San Miguel Equity Securities) after ISM divested its own in ETPI.
