ADVANCED INFO SVCS-SPON ADR Business Summary

Advanced Info Service Public Company Limited (AVIFY) is Thailand’s leading telecommunications and digital life provider, operating primarily through a subscription-based model across its mobile, fixed broadband, and enterprise segments. The company generates the majority of its revenue from mobile services, leveraging a nationwide 5G network that covers over 95% of the Thai population, and has significantly expanded its footprint in the fixed broadband market following the strategic acquisition of Triple T Broadband (3BB). Its business segments are categorized into Mobile Services, Fixed Broadband (AIS Fibre3), Enterprise Solutions (AIS Business), and Digital Services, which includes the AIS Play entertainment platform and digital financial ventures. In the competitive landscape, AIS maintains a dominant market share in a near-duopoly alongside True Corporation (the merged entity of True and DTAC), while also contending with National Telecom (NT). AIS distinguishes itself through a "Cognitive Tech-Co" strategy, prioritizing network quality, high-ARPU customer retention, and AI-driven infrastructure over aggressive price-based competition. Originally founded in 1986 by Thaksin Shinawatra, the company is currently led by a veteran executive team focused on digital transformation. Chief Executive Officer Pratthana Leelapanang, a 20-year company veteran who previously served as COO and Chief Consumer Business Officer, assumed the top leadership role in late 2025. He is supported by Tee Seeumpornroj, who serves as Deputy CEO and CFO while also heading the Broadband Business, and Chief Technology Officer Kitti Ngarmchatetanarom. The leadership team is further bolstered by Chief Information Officer Bharat Alva, who brought extensive international experience from senior roles at Optus and Telkomsel upon joining in 2024. The company’s governance is overseen by Chairman Kan Trakulhoon, former CEO of Siam Cement Group. AIS is backed by a powerful shareholder base including Intouch Holdings—controlled by Gulf Energy Development and Singapore’s Temasek—and Singapore Telecommunications (Singtel), providing the firm with significant regional capital and technical expertise.
