Indonesia’s dominant mobile tower operators are positioning themselves for a potential consolidation move as Mitratel, the infrastructure arm of telecom firm Telkom, has asked financial advisers to submit proposals for a merger with competitor Tower Bersama. According to reports regarding the early-stage evaluations, a combined entity could control more than half of the country’s cellular infrastructure market and reach a total value of roughly 70 rupiah trillion, or 4 billion dollars.
Scale and Bargaining Power in Indonesia’s Tower Market
The Indonesian mobile tower sector operates primarily as a two-player game, giving immense market leverage to its largest participants. Tower companies own the tall structures carrying wireless antennae, collecting rent from mobile carriers for every antenna placed on their properties. According to annual reports and market data, Mitratel currently operates more than 40,230 towers, while Tower Bersama maintains more than 24,000 telecom sites. Operating at this scale allows infrastructure owners to secure better financing, spread operating costs across a wider network, and strengthen their bargaining position against phone companies.
The rapid expansion of mobile data use across the thousands of islands in the Indonesian archipelago has driven this infrastructure leasing model. Because mobile carriers frequently outsource their physical assets to independent operators, industry consolidation remains a recurring theme. A larger asset owner can spread fixed property costs efficiently, while lenders favor larger tower owners due to their predictable income streams. Building towers requires significant capital, and upgrading existing structures for new wireless networks remains costly.
Did You Know? A merger between Mitratel and Tower Bersama is not a new concept; the exact same two companies attempted a merger in 2015, though those discussions fell apart before any contract was signed.
Market Pressures and Financial Realities Behind the Talks
Both companies have faced significant downward pressure on the stock market recently, creating renewed incentives to return to the negotiating table. Mitratel’s shares have dropped 37 percent, while Tower Bersama has fallen 46 percent, with both declines exceeding the drop seen in the broader Jakarta Composite Index. Merging operations could significantly reduce corporate costs and secure a lower cost of debt for the combined entity.
Stock market investors have remained cautious, showing little of the immediate excitement typically associated with multi-billion-dollar deals, largely due to the failure of the previous 2015 attempt. The transaction remains far from complete. Banks have not yet been formally hired, and both the structural layout and the final valuation of the deal still need to be decided. Mitratel confirmed that early evaluations are currently underway while declining to offer additional details, and Tower Bersama did not respond to requests for comment.
Expert Insight: Consolidating Indonesia’s two largest tower portfolios addresses the core economic realities of infrastructure leasing—namely, that fixed-cost dilution and lender preference heavily favor massive scale. While prior negotiations collapsed and equity markets remain cautious, the severe share price declines experienced by both operators provide a powerful catalyst to revisit structural integration.
