2. PT Bayan Resources Tbk (BYAN) sebagai aset terbesar Low Tuck Kwong 
PT Bayan Resources Tbk (BYAN) is undeniably the company most closely associated with Low Tuck Kwong. He founded the enterprise in 1997, initially naming it PT Gunungbayan Pratamacoal, and meticulously developed it into a leading low-cost coal producer. BYAN currently operates significant coal concessions across East and South Kalimantan, with the Tabang mine in Kutai Kartanegara contributing a remarkable 80 percent of its total production. This unwavering commitment to cost efficiency remains a cornerstone of BYAN’s competitive advantage in the global market.
BYAN officially debuted on the Indonesia Stock Exchange (IDX) on August 12, 2008, issuing 833 million shares at an offering price of IDR 5,800 per share. Since its Initial Public Offering (IPO), the company has consistently expanded its operational capacity, solidifying its dominant position within the national coal industry.

This substantial ownership firmly establishes him as the company’s primary controlling shareholder. On October 17, 2025, BYAN’s stock closed at IDR 18,150 per share. While this reflected a 7.75 percent decline over the past six months and a 12.21 percent year-to-date correction, it largely mirrors the broader pressures experienced by the coal market throughout the year.
3. PT Samindo Resources Tbk (MYOH) sebagai bagian portofolionya 
PT Samindo Resources Tbk (MYOH), a prominent coal mining services company, also forms an integral part of Low Tuck Kwong’s diverse investment portfolio. Initially an information technology firm, MYOH underwent a significant transformation following its acquisition by ST International Corporation from South Korea. This strategic acquisition paved the way for MYOH to pivot its core business, evolving into an integrated mining services provider and marking its decisive entry into the energy sector.
Post-transformation, MYOH bolstered its business lines through the acquisition of several subsidiary entities. Notably, one of the major mines managed by its subsidiaries is situated at the mining location of PT Kideco Jaya Agung in East Kalimantan. MYOH’s comprehensive service offerings span overburden removal, coal hauling, and overall mine operational management. This capability to provide end-to-end services firmly positions MYOH as a strategic partner for major coal companies across Indonesia.
As of September 30, 2025, Low Tuck Kwong held 312 million shares in MYOH, constituting 14.18 percent of the total outstanding shares. On October 17, 2025, MYOH’s stock closed at IDR 1,670 per share. While the stock experienced a 7.73 percent decline over the last six months, it managed a modest 3.73 percent year-to-date growth. This performance suggests a relative stability for MYOH, even amidst the prevailing pressures in the broader coal industry.
Collectively, Low Tuck Kwong’s ownership in both BYAN and MYOH powerfully illustrates his commanding presence within the Indonesian coal industry. By strategically controlling both a mining company and a crucial mining services provider, he has meticulously constructed a mutually supportive business ecosystem.
