PRESS RELEASE
PT ANTAM Tbk

For immediate release

Upstream Operations in East Halmahera, ANTAM and CBL have formed a joint venture for nickel
mining operations to supply the battery industry. They are also building RKEF and HPAL processing
plants and the Buli Industrial Area (KIB), which will be supported by clean energy, an integrated
water system, and a cloud-based control centre.

ANTAM President Director Achmad Ardianto explained that the RKEF plant will adopt the world's
first automated ferronickel refining technology developed by Brunp. An annual production capacity
of 88,000 tons of nickel sets a new benchmark for low-energy green smelting.

“Aligned with ESG practices, we and our strategic partners are committed to creating an
environmentally friendly battery ecosystem to support a sustainable national energy
transition,” he stated.

The HPAL plant, with an annual capacity of 55,000 tons of nickel, will use advanced third-generation
technology and a gravity-based, tiered layout to optimize material flow.

“This integrated project, supplying green energy, aims to strengthen Indonesia's position in
the global sustainable energy sector,” added Ardianto.

Midstream & Downstream in Karawang, IBC and CBL are constructing a Battery Cell Plant as part of
an integrated project. The project includes the development of facilities for producing battery active
materials - precursor and cathode -as well as battery recycling.

IBC President Director Toto Nugroho said that IBC and global partners are preparing a production
line for high-guality battery active materials at KIB. The plant is designed to process 16,000 tons of
nickel sulfate annually, producing 30,000 tons of precursors and 30,000 tons of cathode active
material.

“This upstream facility aims to reduce reliance on imported cathode raw materials - the most
valuable component in a battery cell - while increasing domestic value-added nickel,” said
Toto.

Semi-finished materials will be transported westward to Karawang from East Halmahera. At this
strategic industrial zone, IBC and CBL are building a battery cell factory with an initial capacity of 6.9
GWh (Phase 1), which is projected to scale up to 15 GWh within 5 years. This advanced production
line is expected to begin operations in 2026, producing cells for EV's and Battery Energy Storage
Systems (BESS) for domestic and export markets.

IBC, a consortium of PT Indonesia Asahan Aluminium, ANTAM, PT Pertamina Power Indonesia and
PT Perusahaan Listrik Negara (Persero) along with CBL, is committed to making the Karawang
battery cell factory a regional hub for ASEAN, fulfill Ev and BESS demand in the region. This
commitment is reinforced through a joint venture agreement already in place.

For immediate release

This initiative reflects Indonesia's strategic role in growing the EV ecosystem in ASEAN. It proves that
Indonesia can supply raw materials and transform them into high-value products in the global
battery supply chain.

Looking ahead, IBC and CBL will complete the battery cycle with a recycling plant capable of
processing 20,000 tons of used batteries per year into reusable battery materials. The technology is
said to recover over 9596 of valuable metals, thus reducing carbon emissions and maintaining
circular economy principles.

“Recycling is the key to sustainability. Today's end-of-life battery must become tomorrow's
resource,” said Toto.

Beyond supply chain efficiency, ANTAM and IBC also emphasize social and environmental benefits.
The ANTAM-IBC-CBL consortium is preparing vocational programs for local communities, creating
thousands of new jobs, and supporting the growth of local SMEs. All projects are carried out
according to Environmental, Social & Governance (ESG) standards-from tailings management in
Halmahera to clean energy use in Karawang and safety protocols at recycling facilities.

“Our vision is clear, not just to build factories, but to create an integrated green ecosystem
with broad economic impact while protecting the planet,” Toto concluded.

With this series of strategic projects, ANTAM and IBC hope Indonesia will emerge as a key player in
the global battery industry, not merely as a raw material supplier, but as a producer of high-tech,
high-value-added battery components.
