Ang met San Miguel Corporation chair
Danding Cojuangco in a car repair shop. Cojuangco, a car collector, was looking for a mechanic to repair a broken multimillion-peso sports car that he owned, and he grew angry as the mechanics in the shop weren't able to identify the sports car's defect. Ang approached an angry Cojuangco to tell him what his car defect was. Cojuangco then hired Ang on the spot as his official mechanic. When Cojuangco went on exile with newly ousted dictator
Ferdinand Marcos Sr. (Cojuangco was a well known
Marcos crony involved with the
Coco Levy Fund scam), Ang took care of Cojuangco's cars, house, and investments. When Cojuangco returned to the Philippines, Ang handed back everything Cojuangco entrusted him to. Ang was elected vice-chairman of SMC in January 1999; and later as president and chief operating officer (COO) in March 2002. In June 2012, he gained control of SMC after acquiring the shares owned by Cojuangco. On April 15, 2021, ten months following the death of Cojuangco, SMC amended its by-laws to unify the role, functions and duties of chief executive officer (CEO) to that of the president. On June 10, 2024, Ang became chairman and CEO; and his eldest son, John Paul L. Ang, assumed the positions of vice-chairman, president and COO. SMC shall amend its by-laws to redefine the roles, functions and duties of the chairman and chief executive officer, and the president and chief operating officer, subject to stockholders and SEC approvals. ==References==
