Of STP’s overall fiber network, 2.9k miles (4.6k kilometers) are deployed for mobile backhaul.


Protelindo’s acquisition of STP implies an enterprise value for 100% of the company of $1.68bn USD (24 trillion Indonesian Rupiah). Additionally, the company expects the acquisition of STP to be earnings accretive in 2022.

For 2022, STP expects to generate ~$150m USD (2.1 trillion Indonesian Rupiah) of revenue and ~$130m USD (1.9 trillion Indonesian Rupiah) of EBITDA. Therefore, Protelindo’s valuation of STP represents a ~13x EV/EBITDA multiple.


To fund the acquisition of STP, Protelindo raised $980m USD (14.0 trillion Indonesian Rupiah) of new debt, with the remaining $189m USD (2.7 trillion Indonesian Rupiah) coming from its existing facilities. In turn, Protelindo’s pro forma leverage increased to ~4.5x net debt-to-EBITDA.

Pro forma for Protelindo’s acquisition of STP, the combined company has 28.3k towers and 53.0k tenants, implying a 1.87x tenancy ratio. As such, Protelindo will be Indonesia’s largest tower company, ahead of Mitratel, which recently completed its initial public offering (IPO) and has a portfolio of 28.0k towers in Indonesia.

Finally, in combination with STP, Protelindo (Sarana Menara Nusantara) grows its network to 41.5k miles (66.8k kilometers) of terrestrial fiber and subsea cables.
