Tower Bersama Group

PT Tower Bersama Infrastructure Tbk (TBIG) is a key player in Indonesia's telecommunications infrastructure sector, established in 2004. The company's journey began with the formation of PT United Towerindo in 2003, progressively building its portfolio through both organic development and strategic acquisitions. A significant milestone was its listing on the Indonesia Stock Exchange on October 26, 2010. The company was founded by the investment groups Saratoga Group and Provident Capital Indonesia. Winato Kartono and Hardi Wijaya Liong are noted as founders of Provident Capital. Kartono, a founding partner, previously served as the head of investment banking for Citigroup Global Markets in Indonesia, leveraging extensive experience in finance and investment. Liong, also a founding partner and the current CEO of TBIG, brings a background from Citigroup and Arthur Andersen.

Tower Bersama operates as an independent tower company, primarily generating revenue by leasing space on its telecommunication towers to mobile network operators under long-term contracts. This infrastructure-sharing model provides a stable, subscription-based cash flow and enables telecom providers to expand their network reach without the high cost of building and maintaining their own towers. Its main clients are major Indonesian telecommunication operators, including Telkomsel, which is its largest revenue contributor, along with Indosat and XL Axiata. Beyond tower leasing, the company's business extends to providing access to its Distributed Antenna System (DAS) networks, which enhance wireless signal transmission in high-traffic indoor locations like shopping malls and office buildings. The business model is designed to capitalize on the increasing demand for mobile data and network capacity across the Indonesian archipelago.

The core service of Tower Bersama is providing shared telecommunications infrastructure. As of June 2025, its portfolio included 23,945 telecommunication towers and 111 DAS networks, serving 42,663 tenants. This extensive network allows telecom operators to efficiently deploy their equipment for wireless signal transmission. A key feature of their service is the long-term Master Lease Agreements, which lock in revenue and foster lasting relationships with telecom clients. The company has a history of strategic growth through acquisitions, such as the purchase of 2,500 towers from Indosat in 2012, which substantially increased its revenue generation capabilities. Revenue is primarily derived from its tower segment, with the majority coming from operations within Indonesia.
