Vale Indonesia's business

Vale Indonesia mines nickel laterite ore and processes it into nickel matte, a semi-finished product used as feedstock for the stainless steel and battery industries. All mining and processing operations are located in the Sorowako Block, Nuha district, East Luwu regency, South Sulawesi. The company uses pyrometallurgy, a high-temperature smelting process that separates nickel from its ore.

Annual nickel production averages around 75,000 metric tons. The entire output is sold to two buyers under long-term contracts: Vale Canada and Japan's Sumitomo Metal Mining Co., Ltd. This concentrated sales structure is a distinctive feature of Vale Indonesia's business compared with nickel miners that sell more broadly to the domestic market.

The company's current operating area spans 118,017 hectares, spread across South Sulawesi (70,566 hectares), Central Sulawesi (22,699 hectares), and Southeast Sulawesi (24,752 hectares). This is down from an original 190,510 hectares under the initial Contract of Work, following a 2014 renegotiation and the release of 418 hectares in 2017 for a local government integrated development zone.

To power its operations, Vale Indonesia runs three hydroelectric plants: Larona (165 MW, operating since 1979), Balambano (110 MW, 1999), and Karebbe (90 MW, 2011). About 38% of the company's operational energy consumption comes from these three plants, classified as renewable energy.

Beyond mining activities, the company runs a land reclamation program through a modern seedling nursery operating since April 2006. The 2.5-hectare facility produces an average of 700,000 seedlings a year and is used to rehabilitate more than 100 hectares of former mining land annually. In 2014, the company also built 80 settling ponds using Lamella Gravity Settler wastewater treatment technology, an investment of 3.5 million US dollars described as the first of its kind in Indonesia's mining industry.

The company is currently building new nickel processing plants in Sambalagi, Morowali regency, Central Sulawesi, and in Pomalaa, Kolaka regency, Southeast Sulawesi, together with partners. The project relates to high pressure acid leaching (HPAL) technology, a processing method increasingly needed to turn lower-grade nickel ore into feedstock for electric vehicle batteries.

Brief history and IPO

Vale Indonesia's first Contract of Work, back when the company was still named PT International Nickel Indonesia, was signed in 1968. Commercial nickel production began in 1978, with the first shipment going to Japan. The company listed on the Jakarta Stock Exchange (now IDX) on May 16, 1990, through an IPO covering 21.18% of its shares.

Key milestones since then include:

• 1996: the Contract of Work was renegotiated, extending operations through 2025.
• 2011: the company changed its name from PT INCO to PT Vale Indonesia Tbk, coinciding with the Karebbe hydro plant coming online.
• 2014: the Contract of Work was amended, including a reduction in concession area.
• 2015: the company recorded its highest-ever production at 81,200 metric tons and introduced organic rice farming in the community empowerment area around Sorowako.
• 2018: the company recorded 17.4 million work hours without a lost time injury, from April 5, 2017 to April 5, 2018.
• 2019: Vale Indonesia received the PROPER Hijau (Green) rating from Indonesia's Ministry of Environment and Forestry.
• 2020: the Indonesian government, through MIND ID (PT Indonesia Asahan Aluminium), acquired a 20% stake via a divestment scheme.
• May 13, 2024: the company secured a Special Mining Business License (IUPK) valid through December 28, 2035, a 10-year extension beyond the Contract of Work's expiry on December 28, 2025.

Shareholders and management

Based on available sources, Vale Indonesia is part of Vale, the Brazilian multi-mining company, which acts as the controlling shareholder. The Indonesian government, through MIND ID (PT Indonesia Asahan Aluminium), has held a 20% stake since the 2020 divestment. Current board and management names are not mentioned in the sources checked, so investors looking for the latest management structure should check the company's annual report or official website directly.

Recent financial performance

In the first half of 2026, Vale Indonesia posted net profit of 104.37 million US dollars, equivalent to roughly Rp1.87 trillion, a jump of 313.4% year on year compared with the same period a year earlier. Revenue for the same period rose 27.26% year on year to 543.06 million US dollars, according to a Kompas report citing the company's performance data.

The fact that profit growth far outpaced revenue growth is typically linked to a combination of higher nickel selling prices and production cost efficiencies, though the specific breakdown is not detailed in this source. For complete quarterly or semi-annual financial statements, investors should check the official filings published on idx.co.id.

Dividends

The sources checked do not mention Vale Indonesia's dividend policy or payment history. Investors looking for details on dividend distribution, payout ratio, or cum-date schedules should refer directly to the company's disclosures on idx.co.id or Vale Indonesia's official website.

INCO stock price movement

As of October 26, 2026, INCO traded at Rp3,800, only slightly above the lower bound of its 52-week range at Rp3,210 and far from its peak of Rp7,900. This position shows the stock sitting near the bottom of its one-year range, after a string of corrections: down 19.5% over one month and 22.0% over three months. On a one-year basis, the decline is more moderate at 10.0%.

There was a brief rebound moment. On October 22, 2026, according to a Kompas report, INCO shares jumped 5.12% to Rp3,900 during the midday session, following a 4.4% gain in ANTM shares. BRI Danareksa Sekuritas assessed that the rally came after the stock endured heavy selling pressure, though it had not yet confirmed a trend reversal since it still faced key resistance around the 4,047 level, close to its 20-day moving average at 4,097. If that level were broken, the next upside target would be 4,560, which also marks the resistance of the stock's downtrend line. On the downside, the 3,600 area was cited as the nearest support to hold. The MACD indicator at the time remained in negative territory and below its signal line, suggesting recovery momentum had not yet strengthened enough to confirm a reversal.

Recent news and catalysts

Several developments are worth tracking for INCO shareholders:

• October 22, 2026 (Kompas): INCO and ANTM rebounded after a sharp correction, alongside a report of first-half 2026 net profit surging 313.4% year on year to 104.37 million US dollars and revenue up 27.26% year on year to 543.06 million US dollars.
• October 20, 2026 (Liputan6): Vale Indonesia faces rising sulfur prices ahead of developing a new HPAL-based nickel processing facility, a cost challenge for its expansion projects in Sambalagi and Pomalaa.
• October 19, 2026 (TopBusiness and Liputan6): INCO appeared on a BNI Sekuritas trading idea list alongside TINS, NCKL, AADI, CPIN, and TAPG, amid negative market sentiment following MSCI's proposal to downgrade Indonesia's market status from emerging market. On October 16, 2026, the IHSG plunged 11%, its deepest drop since 1998, accompanied by roughly Rp3.4 trillion in net foreign selling, with high foreign-ownership stocks like BBCA, BBRI, BMRI, ANTM, and TLKM among the most sold. Fanny Suherman, Head of Retail Research at BNI Sekuritas, said in her research note that investors should avoid stocks with high foreign ownership for now, given the impact of the potential MSCI downgrade.

What this means for investors

There are a few concrete points worth watching for INCO in the near term, not as a buy or sell signal but as a way to read where the stock might head.

On the technical side, the resistance at Rp4,047 and the 20-day moving average at Rp4,097 will determine whether the October 22 rebound continues or fades as a short-lived bounce after a deep correction. If both levels are cleared, the next target sits around Rp4,560, which also marks the stock's multi-month downtrend line. On the downside, the Rp3,600 support is the level analysts typically watch as a sign of renewed weakness if it breaks.

On the fundamental side, the next quarterly or semi-annual earnings report will show whether the 313.4% year-on-year profit surge in the first half of 2026 can continue, or whether it already peaked on the back of temporary nickel price factors.

Macro sentiment is also worth tracking. The MSCI downgrade proposal for Indonesia's market status, which triggered an 11% correction in the IHSG on October 16, 2026, leaves high foreign-ownership stocks like INCO exposed to renewed pressure if there is further clarity on MSCI's decision.

Finally, progress on the HPAL projects in Sambalagi and Pomalaa, including the impact of rising sulfur costs on production expenses, is worth following since it could affect Vale Indonesia's margins once those facilities come online.

Competitors on the IDX

A few nickel and metal mining issuers commonly compared with INCO on the IDX:

• ANTM (Aneka Tambang): a state-owned miner with a more diversified portfolio spanning nickel, gold, and bauxite, unlike INCO's focus on nickel matte.
• NCKL (Trimegah Bangun Persada): a private nickel producer with operations outside South Sulawesi, often mentioned alongside INCO in mining stock research.
• TINS (Timah): a state-owned tin miner whose main commodity differs from nickel, but is often grouped with INCO as both move with similar mining sector sentiment.

Risks

Some concrete risks worth monitoring for INCO shareholders:

• Commodity price risk: INCO's revenue depends heavily on global nickel prices, which fluctuate with demand from the stainless steel and electric vehicle battery industries.
• Regulatory and licensing risk: even though its IUPK has been extended through 2035, Indonesia's mining business remains subject to government policy changes, including concession area rules and downstream processing obligations.
• Customer concentration: all of the company's nickel matte output is sold to two buyers, Vale Canada and Sumitomo Metal Mining, under long-term contracts. This reliance on two partners leaves the company exposed if contract terms or buyer policies change.
• Production cost risk: reported rising sulfur prices ahead of the new HPAL facility development could pressure margins on the Sambalagi and Pomalaa expansion projects.
• Market and liquidity risk: INCO is among the stocks flagged as having high foreign ownership, making it vulnerable to macro sentiment shifts such as the MSCI downgrade proposal for Indonesia's market status.
• Price technical risk: the stock remains below key resistance levels (4,047 and the MA20 at 4,097) with a negative MACD reading, indicating the recovery trend has not been strongly confirmed.
