Ramon Ang

Ang is the son of ethnic Chinese parents.

Ang grew up in Tondo, Manila and worked in his father's automobile repair shop. He was a dealer of used Japanese car and truck engines. As working student, he holds a Bachelor of Science degree in mechanical engineering from Far Eastern University.

Ang served as managing director of the magwheel manufacturing company Commodore in the 1980s. He also participated in several autoslalom races he organized as company head, being proclaimed Slalom Champion of the Year in 1988 by the RACE Motorsports Club.

San Miguel Corporation

Ang met Danding Cojuangco, the chairman of San Miguel Corporation, 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 (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. Simultaneous to his position at SMC, Ang also owned the real estate firm Centech, which was alleged to have been involved in business deals with the Estrada family during the presidency of Joseph Estrada. 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.

Ang was married to Tessie. They have eight children: Cecile, Monica, Jacqueline, Carmela, John Paul, and Jacob. John Paul is president of Eagle Cement Corporation and San Miguel Corporation's vice chair, president and COO. Monica is a finance officer. Cecille is manager of the family-owned Diamond Hotel Manila Bay. On Holy Saturday, April 11, 2020, Jomar (b. 1993), Ang's third child died after a serious injury.
