Press Release

Jakarta, October 1, 2026 – PT Dian Swastatika Sentosa Tbk (IDX: DSSA) ("DSSA" or the "Company") announced its consolidated financial performance for the six-month period ended June 30, 2026. DSSA recorded revenue of USD 1.77 billion, up 34.0% from USD 1.32 billion in the same period last year. In line with this growth, profit attributable to owners of the parent entity rose 79.6% to USD 174.4 million. As of June 30, 2026, DSSA reported total assets of USD 6.08 billion and total equity of USD 3.05 billion.

"Our first-half 2026 performance reflects the consistency of the Company's diversification strategy. Growing demand for data, connectivity, and artificial intelligence has become the main driver of our digital business development. By strengthening integrated digital infrastructure, from fiber-optic networks and data centers to AI-based solutions, we are committed to driving equitable access to technology across Indonesia, while maintaining our strength in the energy sector as the foundation for sustainable growth," said L. Krisnan Cahya, President Director of DSSA.

Driving the Energy Transition and Equitable Access to Technology

This performance comes amid two major trends shaping Indonesia's economy. The rapid adoption of artificial intelligence (AI) is fueling a surge in demand for data centers and high-capacity connectivity, most of which remains concentrated on Java. At the same time, national power sector development is increasingly anchored in new and renewable energy. Together, these trends underscore that the growth of the digital economy requires a reliable and evenly distributed supply of clean energy.

Against this backdrop, the Company's performance is supported by its diversified business model, in which each pillar reinforces the others. The energy pillar, through coal mining and trading, recorded revenue of USD 1.53 billion, up 29.8%, and remains a solid source of cash flow. The technology and digital infrastructure pillar recorded revenue of USD 182.2 million, up 89.3%. Cash flow from the energy business gives the Company room to invest in renewable energy and digital infrastructure, while the growth of the digital economy, including the use of artificial intelligence (AI), requires a reliable and increasingly clean energy supply.

In the energy pillar, the Company continues to develop new and renewable energy. Through PT Daya Mas Bumi Sentosa, a joint venture with PT FirstGen Geothermal Indonesia, the Company is developing geothermal working areas, most of which are located outside Java. Meanwhile, PT Trina Mas Agra Indonesia manufactures solar cells and modules domestically to support the government's solar power program. Both initiatives aim to expand access to reliable and evenly distributed clean energy across Indonesia.

In the technology pillar, MoraRepublic is accelerating its post-merger expansion by extending its fiber-to-the-home network to 186 cities and regencies. To reach areas not yet served by fixed-line networks, MoraRepublic has launched MyRepublic Air, an affordable fixed wireless access (FWA) home internet service starting from IDR 100,000 per month, targeting tier-2 and tier-3 cities in Sumatra, Kalimantan, Sulawesi, Bali, and Nusa Tenggara. The service reflects the commitment to providing affordable internet for the people while accelerating equitable digital access beyond Java. The integration of its backbone network, including the Palapa Ring West and East Packages, with its last-mile network to customers' homes positions MoraRepublic as a fully integrated, end-to-end connectivity provider.

On the computing side, SM+, together with Korea Investment Real Asset Management (KIRA) and LG Sinar Mas, is completing SMX01, an AI-ready data center in Jakarta's central business district that has reached the topping-off stage and is targeted to be operational in the fourth quarter of 2026. SMX01 complements SM+'s network of edge data centers across Indonesia, bringing digital services closer to users.

In line with this strategy, the Company carried out several corporate actions during the second quarter of 2026, including a 1:25 stock split, the merger of MORA and PT Eka Mas Republik into PT Ekamas Mora Republik Tbk (MoraRepublic), and the establishment of an AI joint venture with iFLYTEK.

Backed by a solid financial position, with cash and cash equivalents of USD 723.3 million as of June 30, 2026, up 75.2% from the end of 2025, the Company will continue to strengthen synergies across its business pillars, spanning energy, technology and digital infrastructure, and investment. Through these synergies, the Company aims to deliver sustainable growth and contribute to accelerating Indonesia's digital transformation and energy transition, while driving equitable access to digital services and clean energy for communities across Indonesia.
