In the first half of 2025, the Company recorded a net loss of USD 115.3 million. This figure was
largely due to the recognition of a non-cash loss from the divestment of two coal-fired power
plant subsidiaries—namely PT Minahasa Cahaya Lestari (MCL) and PT Gorontalo Listrik
Perdana (GLP)—which were completed in March and May 2025. The non-cash loss from this
divestment was recorded at USD 96.9 million. This loss did not impact the Company's cash
flow; instead, it generated additional fresh funds in the form of an inflow into TBS's cash of USD
123.6 million. This strengthens the Company's fundamental operational condition, which
remains stable during the transition period.

The sale of the two power plants contributed significantly to the reduction of the Company's
carbon emissions by 1.4 million tons of CO₂ equivalent (tCO₂e)—equivalent to an 86% emission
reduction in one year. The calculation was carried out based on the Greenhouse Gas Protocol
methodology, and the Company's 2024 emission data has been reviewed through a limited
assurance process by EY Indonesia. This achievement is a significant milestone in accelerating
TBS's transition towards its carbon neutral target by 2030.

Meanwhile, TBS's new pillar in the waste management business has begun to show significant
positive contributions. This business unit recorded revenue of USD 59.6 million with EBITDA
reaching USD 10 million by the end of June 2025. Thus, an EBITDA margin of 17% was
achieved, reflecting higher efficiency and profitability potential compared to TBS's coal line. This
achievement is an early signal of the success of TBS's transformation direction and strengthens
this sector's position as one of the drivers of sustainable growth going forward.

The acquisition of Sembcorp Environment Pte. Ltd. in March and then Sembcorp Enviro Facility
Pte. Ltd. in May 2025 also expanded TBS's capabilities in the regional waste treatment sector.
"We see the waste management business as a key element in TBS's future transformation.
Besides having strong growth potential, this sector makes a real contribution to the environment
and the quality of life of the community. With the capabilities and scale we currently have, we
believe this business will be one of the main drivers of TBS's long-term growth," said Juli
Oktarina, Director of TBS.

As part of the expansion of its renewable energy portfolio, TBS is also developing two strategic
projects that reflect the Company's commitment to a clean energy transition. The Tembesi
Floating Solar Power Plant in Batam, with an installed capacity of 46 MWp, is one of the largest
floating solar power plant projects in Indonesia, developed in collaboration with PLN Nusantara
Power. This project has achieved financial closing and is targeted to reach commercial
operation (COD) in the second half of 2026. Meanwhile, through its associated entity, PT
Adimitra Energi Hidro (AEH), TBS also operates the Sumber Jaya Mini Hydro Power Plant with
a capacity of 6 MW, which has officially commenced commercial operation since 22 January
2025. These two projects reinforce TBS's tangible steps in supporting the national energy mix
and the development of low-carbon energy infrastructure in Indonesia.

In the electric vehicle ecosystem sector, Electrum continues to accelerate Indonesia's transition
to sustainable electric mobility. As of 20 July 2025, Electrum recorded significant progress in
encouraging electric vehicle adoption in Indonesia. The number of electric motorcycle (E2W)
units in operation reached 5,406 units, an 87% increase compared to the same period last year.
Infrastructure growth was also very rapid, with the number of battery swap stations (BSS)
surging 150% to 320 points from the previous 128 points. Currently, more than 21,000 battery

swaps occur daily, reflecting the high user trust and engagement with the Electrum ecosystem.
Not only does it impact operational aspects, but Electrum also provides real added value for
driver partners. The average daily income of partners increased by 25% thanks to operational
cost efficiency from the use of electric motorcycles. On the environmental side, this initiative has
contributed to a carbon emission reduction of more than 20 tons of CO₂ per day, reinforcing
Electrum's role in supporting national sustainability targets.

Juli also stated that this year is a significant milestone in TBS's transformation towards a more
sustainable business. "We are in a strategic phase to reposition our portfolio and focus on
developing businesses that not only have long-term growth potential but also contribute
positively to the environment and society," Juli concluded optimistically.
