Henry 'Big Boy' T. Sy Jr. is a Filipino businessman, the billionaire Chairman of SM Prime Holdings, Inc. (PSE: SMPH), the largest property developer and mall operator in the Philippines. He is the eldest son of the late founder, Henry Sy Sr. (d. 2019), who built the colossal SM Investments empire from a small shoe store.

Sy Jr. is a Civil Engineer by training, holding a B.S. degree from De La Salle University (like all his brothers). His career is defined by his executive leadership in the family's property division, leveraging his engineering expertise to oversee the massive construction, development, and expansion of the SM Malls across the Philippines and China.

Henry Sy Jr. has been a Director of SM Prime since 1994. His strategic leadership guided the company's exponential growth, transforming SM Prime into the largest, most dominant property developer in the Philippines. As Chairman, he is responsible for the Group's real estate acquisitions, development activities, design ideas, and negotiation for potential sites.

The family's wealth is secured by the immense, long-term appreciation of SM's real estate portfolio and the successful vertical integration of the empire (connecting retail, banking, and property). Sy Jr. and his siblings (who all hold executive posts in the diversified conglomerate) ensure the generational continuity of the legacy, maintaining the family's control over their core assets, which include SM Malls and BDO Unibank (the largest bank in the Philippines).

Henry Sy Jr.'s social impact is structural, stemming from SM Prime's role in shaping the Philippines' urban and commercial environment through its massive mall and property developments. The company provides thousands of stable jobs in construction, retail, and management.

His family's philanthropic arm, the SM Foundation, supports various educational and community initiatives. His structural contribution is tied to the successful generational transition and consolidation of the nation's largest conglomerate.

Henry Sy Jr. maintains the professional, composed style of a major Asian corporate executive. His attire is consistently formal and high-quality, favoring tailored business suits. His aesthetic is one of stability and serious authority, reflecting his engineering background and mastery of large-scale construction.

Residing in Manila, Philippines, his luxury is the immense security and financial reward derived from his multi-billion dollar fortune. His life is dedicated to the stewardship of his family's legacy, managing the real estate and property development of the largest conglomerate in the Philippines.
