PT Sarana Menara Nusantara Tbk.

Indonesia · IDX: TOWR.JK · Market cap: $1.2B · P/E: 5.5 · P/S: 1.5

It owns and rents out telecom towers and provides network services that help mobile operators connect their customers across Indonesia.

Sarana Menara Nusantara is one of Indonesia's biggest independent owners of telecommunications towers. Mobile operators like Telkomsel and Indosat need towers to hold their antennas so phones can get a signal, but building and maintaining thousands of towers is expensive and slow. Sarana Menara builds them instead, then rents space on each tower to multiple operators at once. One tower, several paying tenants—that is the core of the business.

Telecom tower leasing
Telecom towers are rented out to mobile operators who mount their antennas on them.

The company's main brand is Protelindo, which runs the tower leasing operation. It also offers wireline and VSAT satellite services, mainly through a subsidiary called Iforte, which provides fiber connections and data links to operators and businesses. So it earns money two ways: monthly rent from towers and fees for the network connections that carry data between cell sites and the wider internet. The tower business is attractive because it behaves like a toll road. Once a tower is built, adding a second or third tenant costs very little extra, so profits climb. The risk sits on the other side of the table: the customers are a handful of big telecom operators, and if they merge, cut spending, or build their own towers, demand can soften. Rivals in this space include Tower Bersama Infrastructure and the tower arms of the operators themselves.


Sarana Menara is controlled by the Sampoerna family and has grown largely by buying up smaller tower companies and expanding its portfolio. It is a steady, cash-generating infrastructure business rather than a fast-growing tech story—the kind of company that quietly underpins everyday mobile phone service without most people ever noticing its name.
