While most players in the chemical fiber industry struggle with thin margins, Hengyi Petrochemical has delivered a staggering performance. In the first half of 2026, the only Chinese chemical fiber leader with an overseas refinery expects net profit of 5.5 to 6.0 billion RMB, surging 2,326% to 2,547% year-on-year. This record not only breaks the company's own benchmarks but fully demonstrates the synergy of industry cycles and strategic layout.
Dual Engines of Profit Explosion
Hengyi's profit peak was not built in a day. In Q1, net profit reached 1.995 billion RMB, up 3,773.77% year-on-year. In Q2, it further rose 76% to 101% quarter-on-quarter, reaching 3.5 to 4.0 billion RMB. This accelerating trend is driven by two powerful engines.
The first is the Brunei refinery. Southeast Asian refined oil markets have been persistently tight, with spreads widening sharply in Q1 2026. Thanks to tax incentives, market-based pricing, and low shipping costs, the Brunei plant operated at full capacity with high per-ton margins, allowing Hengyi to enjoy exceptional overseas refining profits while domestic peers faced pressure.
The second engine comes from the PTA and polyester segments. Industry anti-competition measures have optimized capacity structures, making profit recovery sustainable. Combined with the ramp-up of nylon capacity and warmer polyester markets, Hengyi's profit structure has evolved from relying solely on polyester to a healthier 'refining plus polyester' dual-drive model.
Three Mega Projects Reshaping the Landscape
Amid short-term profit surges, Hengyi is accelerating three strategic projects for long-term growth. The Brunei Phase II project, fully launched, will have an optimized capacity of 12 million tons per year, producing high-value products like diesel, PX, and benzene, targeting completion by end-2028. This will bring total Brunei capacity to 20 million tons per year, making it the only new private mega-refinery capacity overseas in recent years.
The Xinjiang coal-to-ethylene glycol project aims to produce 2.4 million tons per year of fiber-grade MEG, expected to start production in H1 2028. This reduces dependence on crude oil and hedges against oil price volatility.
The most intriguing is the Hubei Jingzhou recycled materials project, a 300,000-ton-per-year demonstration facility using waste textiles as feedstock instead of crude oil, with an 18-month construction period. Aligned with China's 'dual carbon' strategy, this project will give Hengyi a unique 'oil-coal-textile' integration, enhancing profit stability across the full chain.
Can the Boom Last?
The key question is whether the 23-fold growth is sustainable. From an industry perspective, the tight supply-demand balance in Southeast Asian refined oil markets is unlikely to reverse soon, supporting high Brunei margins for the rest of the year. PTA and polyester capacity structures have been meaningfully optimized, and profit recovery is sustainable. With nylon projects ramping up, the full-year profit base will be permanently elevated.
However, risks remain. A sharp drop in crude oil prices could cause inventory write-downs and narrow crack spreads. The large-scale projects face execution delays and capital pressure. Concentrating core refining capacity in Brunei exposes the company to policy and geopolitical changes. Finally, weaker-than-expected downstream textile demand could slow polyester profit recovery.
Overall, Hengyi's 23-fold profit surge is not a cyclical fluke but the culmination of years of global expansion and full-chain integration. Short-term growth is highly certain; long-term, as the three projects come online, Hengyi will transform from a 'refining and chemical fiber leader' into an 'oil-coal-textile integrated new materials company,' enhancing its growth profile. For cyclical stocks, profit certainty and growth sustainability are the core drivers of valuation re-rating.
