The strategic alliance between two prominent Indonesian conglomerates, led by Prajogo Pangestu and Happy Hapsoro, has once again captured significant market attention. Their respective entities, PT Singaraja Putra Tbk (SINI) and PT Petrosea Tbk (PTRO), have forged a comprehensive partnership to develop SINI’s coal mining assets in Central Kalimantan. This collaboration is poised to become a significant new catalyst, driving substantial growth and enhancing the long-term value proposition for both companies within Indonesia’s dynamic mining sector.
At the heart of this partnership lies a pivotal Mining Services Agreement. Through its two subsidiaries, PT Pesona Bara Cakrawala (PBC) and PT Cakrawala Bara Persada (CBP), SINI officially signed this agreement with PTRO. Under the terms of this extensive contract, PTRO will undertake the comprehensive development of SINI’s coal mining operations. This encompasses crucial activities ranging from initial overburden removal to the actual coal mining production, all situated in the strategic Kapuas Tengah District, Kapuas Regency, Central Kalimantan. The scope of work highlights PTRO’s expertise as a leading mining services provider.
This landmark agreement is structured to endure for the entire life of mine, signaling a long-term commitment and strategic alignment between the two entities. SINI projects that this collaboration holds the potential to generate substantial additional revenue, estimated to reach an impressive Rp 57.05 trillion throughout the duration of the contract. This significant figure underscores the scale and financial impact anticipated from the integrated mining operations, promising robust returns for SINI’s stakeholders and reinforcing its position in the market.
Delving into the specifics, the mine operated by PBC is projected to involve an extensive overburden removal volume of approximately 189 million bank cubic meters (BCM). Concurrently, the expected coal production from this site is estimated at around 42 million tons. Based on these projections, SINI anticipates a potential revenue generation of approximately US$ 2.6 billion, which translates to a substantial Rp 45.57 trillion, specifically for coal with a calorific value of GAR 4,200. These figures highlight the immense scale of the mining operations and the significant economic contribution expected from the PBC asset.
Furthermore, the mining concession under CBP is slated for equally significant development. This project is forecasted to involve an overburden removal volume of roughly 40 million BCM, coupled with an estimated coal production of 8 million tons. The revenue potential from this particular project is projected to reach approximately US$ 656 million, or about Rp 11.48 trillion, for coal with a higher calorific value of GAR 5,000. The combined prospects from both the PBC and CBP mines solidify the substantial revenue streams and operational expansion that this partnership is set to unlock for SINI.
In an official disclosure to the Indonesia Stock Exchange (IDX) on Friday, July 24, 2026, SINI’s management emphasized the strategic objectives behind this collaboration. “This partnership aims to support the achievement of optimal coal production targets and the implementation of Good Mining Practices, thereby providing added value for the Company and all its subsidiaries,” the statement detailed. This commitment to both efficiency and responsible mining practices underscores the comprehensive approach adopted by the partners, aiming for sustainable growth and operational excellence.
Beyond securing the crucial mining services contract, PTRO has also strategically bolstered its position as a significant shareholder in SINI. On July 23, 2026, PTRO successfully completed the execution of its Rights Issue (HMETD), contributing approximately Rp 1.19 trillion in capital. Following this substantial transaction, PTRO’s ownership stake in SINI has increased markedly, reaching 19.88%. This move signifies a deeper strategic alignment and commitment from PTRO, transforming it from merely a contractor to a substantial equity partner in SINI’s future endeavors.
Concurrently with its increased shareholding, PTRO executed another significant corporate action by transferring 99.99% of its ownership in PT Kemilau Mulia Sakti (KMS) to SINI. KMS, in turn, is the holding company for PT Cristian Eka Pratama (CEP), a prominent coal mining company that holds an Izin Usaha Pertambangan Operasi Produksi (IUP-OP), or Production Operation Mining Business Permit, in Kutai Barat Regency, East Kalimantan. This strategic transfer significantly expands SINI’s asset base and operational reach within the Indonesian mining landscape.
The integration of CEP into SINI’s portfolio marks a pivotal moment, complementing its existing array of mining assets which previously included PT Persada Kapuas Prima, PT Pasir Bara Prima, PT Pesona Bara Cakrawala, and PT Cakrawala Bara Persada. Interestingly, CEP, PBC, PBP, and CBP are all existing clients of Petrosea’s mining services. This pre-existing relationship fosters a seamless integration and immediate operational synergy, as PTRO already possesses intimate knowledge of these mining concessions and their operational requirements.
Prospek Saham SINI-PTRO
The dual corporate actions involving the entities linked to Happy Hapsoro and Prajogo Pangestu have drawn keen analysis from market experts. Nafan Aji Gusta Utama, a Senior Technical Analyst at Mirae Asset Sekuritas, views this collaboration as a significant accelerator for SINI’s transformation into a fully integrated coal mining company. This strategic shift is expected to enhance SINI’s operational efficiency and market competitiveness by consolidating its value chain.
According to Utama, the projected additional revenue potential of up to Rp 57 trillion will substantially strengthen SINI’s long-term prospects, providing a clear trajectory for sustained financial growth. Simultaneously, Petrosea benefits immensely by securing a long-term mining contract, which significantly enhances its revenue certainty and bolsters its order book as a leading mining contractor. This dual benefit underscores the win-win nature of the strategic partnership.
Nafan Aji Gusta Utama further highlighted that this collaboration robustly strengthens the synergy between two of Indonesia’s most influential business groups. Prajogo Pangestu, through his association with PTRO, brings invaluable experience in building extensive mining and infrastructure value chains, leveraging decades of industry expertise. On the other hand, Happy Hapsoro gains access to a significantly larger and more diversified portfolio of mining assets through SINI, positioning his group for accelerated expansion and market dominance.
The analyst identified at least five key potential synergies arising from this powerful collaboration. These include: accelerated mine development, which promises to bring assets to production faster; optimal utilization of internal contractors, fostering cost efficiencies and greater control; enhanced production cost efficiency through integrated operations and shared resources; improved access to funding, given the backing of two major conglomerates; and substantial opportunities for future expansion of mining assets, cementing their long-term growth trajectory.
“We recommend to Add (accumulate) PTRO with a target price of 5,625. SINI’s recommendation is currently not rated,” Utama conveyed to Katadata.co.id on Friday, July 24, 2026. This specific guidance offers investors a clear direction regarding PTRO’s stock potential, while indicating that SINI’s valuation may require further assessment following the full integration of its new assets and operational changes.
A similar positive outlook was articulated by Elandry Pratama, Branch Manager of Panin Sekuritas Pondok Indah. He underscored that the contract, valued at approximately Rp 57 trillion, serves as a powerful positive catalyst. This substantial financial commitment significantly enhances the long-term revenue visibility for both companies, providing a clear and predictable earnings stream that is highly attractive to investors.
For PTRO, this collaboration substantially expands its order book as a premier mining contractor, solidifying its market position and ensuring a steady pipeline of projects. Conversely, SINI gains an unparalleled opportunity to accelerate its expansion initiatives and significantly increase its operational scale. This accelerated growth is powerfully supported by the robust synergy between two major business groups, both boasting strong and proven track records within the competitive mining industry.
Despite the broadly positive prospects, Elandry Pratama urged investors to remain vigilant and closely monitor several critical aspects of the project. He emphasized the importance of scrutinizing the actual project execution, carefully assessing the necessary capital expenditure (capex), and paying close attention to operational margins and cash flow performance. According to Pratama, the sheer magnitude of the contract value does not automatically guarantee an increase in profit if the project execution deviates from planned timelines or efficiencies.
For the medium term, looking ahead over the next 12 months, Elandry recommended a target price for PTRO at Rp 6,500 and for SINI at Rp 9,000. These specific target prices provide investors with a forward-looking perspective on the potential appreciation of these stocks, balancing the optimistic outlook with a pragmatic assessment of the operational challenges and opportunities in the dynamic Indonesian mining sector.
