ADRO is the ticker for PT Alamtri Resources Indonesia Tbk, a company engaged in coal mining and services, renewable and non-renewable energy, utilities, minerals, and supporting infrastructure. The company was previously known as Adaro Energy and is known for its low-pollutant coal brand, Envirocoal.

Alamtri Resources' business

Alamtri Resources Indonesia operates in coal mining, renewable and non-renewable energy services, utilities, minerals and mineral processing, and supporting infrastructure. Its flagship product is coal sold under the Envirocoal brand, known for ultra-low ash and sulfur content and low nitrogen levels, positioned as relatively cleaner coal compared to other types.

In 2022, the company produced 62.88 million tons of coal, making it Indonesia's second-largest coal producer by volume at the time. On the 2023 Forbes Global 2000 list, it ranked 1,393rd globally and 7th in Indonesia, one of only two Indonesian coal companies on that list. Beyond thermal coal mining through subsidiary Adaro Indonesia, the group also runs a hard coking coal business through Adaro Minerals and power generation through several coal-fired plants.

Brief history and IPO

The roots of this business trace back to the 1970s, when the Indonesian government divided East and South Kalimantan into eight coal blocks. Spain's Enadimsa took Block 8 in Tabalong, then considered unattractive due to its remote location and lower coal quality. Enadimsa established PT Adaro Indonesia and signed a Coal Mining Concession Agreement (PKP2B) with the government in 1982.

Mining began in 1983. In 1989, a consortium of Australian and Indonesian companies acquired 80% of PT Adaro Indonesia from Enadimsa. Commercial production officially started on October 22, 1992, under the Envirocoal brand already registered a year earlier. The first shipment, 68,750 tons, went to Germany's Krupp Industries on October 22, 1991.

The current holding company was originally established in August 2004 as PT Padang Karunia. In 2005, through PT Alam Tri Abadi, it acquired PT Adaro Indonesia for roughly US$923 million in debt plus US$50 million in equity. In 2008, the company renamed itself PT Adaro Energy Tbk and listed on the Indonesia Stock Exchange that same year.

Post-IPO expansion continued with a 25% stake acquisition in the IndoMet Coal project alongside BHP Billiton in 2010, acquisitions of two coal companies in South Sumatra in 2011, an option to acquire PT Bhakti Energi Persada in 2012, and construction of a 2x1000 MW ultra-supercritical power plant in Batang with J-Power and Itochu starting 2016, backed by a US$4.2 billion investment. In 2018, the company acquired the Kestrel coal mine in Australia, extending its footprint overseas. In the second quarter of 2020, through Adaro Minerals, it began shipping hard coking coal from the Maruwai mine to customers in Japan.

The company changed its name again in November 2024 to PT Alamtri Resources Indonesia Tbk, the name it carries today. This followed an Extraordinary General Meeting of Shareholders (RUPSLB) on February 9, 2022, which eventually led to spinning off the coal trading business into a new listed entity, PT Adaro Andalan Indonesia Tbk (AADI). After the spin-off, ADRO's role shifted from parent of the coal business to a company with a broader energy and infrastructure portfolio.

Shareholders and management

One shareholder actively disclosed in recent filings is PT Trinugraha Thohir, a company owned by Garibaldi "Boy" Thohir. On October 19, 2026, Trinugraha Thohir bought 470,000 ADRO shares at Rp2,130 per share, worth around Rp1 billion. Following this transaction, Trinugraha Thohir's stake in ADRO rose to 209,889,470 shares, or 0.729%, up from 209,419,470 shares (0.727%). The disclosure listed the purpose of the transaction simply as "investment."

ADRO share price movement

As of October 21, 2026, ADRO traded at Rp2,400 per share. That sits roughly in the middle of its 52-week range of Rp1,695 to Rp2,860, about 60% of the way up from the low.

Over the past month the stock fell 8.4%, and over three months it's down 5.5%. On a one-year basis, however, ADRO is still up 41.6%. Average daily trading volume over the past three months reached 40.48 million shares, a fairly active level for a stock this size.

The recent monthly decline traces back to a sharp drop on Friday, October 16, 2026, when ADRO plunged more than 10% in a single day. That slide coincided with the Jakarta Composite Index (IHSG) tumbling 11.57%, which investor.id reported was triggered by an MSCI-related announcement. AADI, part of the same group as ADRO, fell even harder that day, down 12.59%.

Recent news and catalysts

According to Kompas.com on October 20, 2026, ADRO began executing its share buyback on Tuesday, October 20, 2026, with funding of up to Rp5 trillion. Corporate Secretary Maharani Cindy Opssedha said the move reflects the company's confidence in national economic fundamentals and long-term business prospects, while supporting Indonesian capital market stability.

The buyback program was approved by shareholders at the April 17, 2026 annual general meeting, with a 12-month execution window starting April 18, 2026, under OJK Regulation No. 29 of 2023 on share buybacks. Management stressed the buyback would not disrupt the company's investment needs or operations given its strong financial condition and prudent liquidity management. This isn't ADRO's first buyback either; the company previously ran one from May 16 to June 2, 2025, repurchasing 33 million shares.

Per a kumparan.com report, several other issuers took similar action around the same time: PT Barito Pacific Tbk (BRPT) allocated up to Rp1 trillion for buybacks through December 31, 2026, and PT Chandra Asri Pacific Tbk (TPIA) allocated up to Rp1 trillion to repurchase as many as 800 million shares, or 0.92% of outstanding shares, at a maximum price of Rp3,000 per share. This wave of buybacks appears to be a coordinated response by several large issuers to the selloff pressure that hit the market following the mid-October 2026 MSCI announcement.

Meanwhile, the purchase by PT Trinugraha Thohir on October 19, 2026, a day before the official buyback began, shows affiliated parties of the controlling family adding to their stake while the price was under pressure around Rp2,130.

What it means for investors

A few concrete things are worth tracking on ADRO in the near term, without betting on a particular price direction.

• Progress of the Rp5 trillion buyback running since October 20, 2026. How many shares have been repurchased and at what prices is typically disclosed gradually through IDX filings.
• Where the price sits within the 52-week range of Rp1,695 to Rp2,860. The current Rp2,400 level is roughly in the middle, after a drop of more than 10% on October 16, 2026.
• Follow-up on the MSCI-related sentiment that helped drag the IHSG down 11.57% on October 16, 2026. This is worth watching since it could keep affecting sentiment on other large-cap stocks, ADRO included.
• Affiliated-party transactions, such as PT Trinugraha Thohir's purchase on October 19, 2026, which can serve as an additional data point but not a guarantee of future price direction.
• Official financial statements at idx.co.id, since ADRO's latest revenue and profit figures are not covered in the news sources used for this article.

There's no guarantee the buyback or any particular sentiment will push ADRO's price in a given direction. Investment decisions should still rest on independent research and individual risk tolerance.

Competitors on the IDX

A few coal mining issuers commonly compared with ADRO on the IDX:

• PTBA (Bukit Asam): a state-owned (BUMN) coal producer with its main mining base in South Sumatra.
• ITMG (Indo Tambangraya Megah): a coal mining company operating in East Kalimantan, known for its strong export orientation.
• AADI (Adaro Andalan Indonesia): the entity spun off from ADRO's own coal business, now operating as a separate listed company.

The key difference between ADRO and these three lies in business structure. ADRO now oversees a broader portfolio spanning energy, utilities, minerals, and infrastructure, rather than being purely a thermal coal miner like PTBA and ITMG.

Risks

Several risks worth monitoring for retail investors interested in ADRO:

• Commodity price risk. ADRO's core business still depends heavily on global coal prices, which can swing sharply and are largely outside the company's control.
• Regulatory risk. Coal mining operations run under PKP2B/IUPK schemes and various environmental and energy regulations that can change, including growing global pressure toward energy transition away from coal.
• Group structure concentration risk. After spinning off its coal trading business into AADI, investors need to understand ADRO's changed business profile to avoid misjudging its current main revenue sources.
• Market volatility risk. The October 16, 2026 incident, when ADRO and the IHSG both plunged double digits in a single day following the MSCI announcement, is a reminder this stock can be highly sensitive to global index sentiment.
• Buyback effectiveness risk. The Rp5 trillion buyback program may cushion selling pressure temporarily, but there's no guarantee it will support the price long term if fundamentals or market sentiment stay weak.
• Liquidity and valuation risk. Despite fairly active daily volume (averaging 40.48 million shares over three months), the sharp price swings seen recently mean this stock can be volatile, so investors should check valuation independently before making any decisions.
