A 23-fold increase in net profit is exceptionally rare in any industry. Hengyi Petrochemical expects H1 2026 net profit attributable to shareholders of RMB 5.5-6 billion, a year-on-year surge of 2326%-2547%. This is not merely a cyclical windfall but the crystallization of a leading chemical fiber company's transition from refining overseas to full-chain restructuring.
Three Pillars of the Profit Explosion
Hengyi's profit structure shows Q1 net profit of RMB 1.995 billion (+3774% YoY), with Q2 sequentially up 76%-101% to RMB 3.5-4 billion. The core driver is the Brunei refining project's locational dividend. Southeast Asian refined fuel supply-demand remains tight, spreads widened sharply in early 2026, and Hengyi is the only Chinese chemical fiber firm with an overseas refinery. The Brunei plant enjoys tax incentives, market-based pricing, and low freight, achieving full capacity and sales.
Beyond refining, nylon chain capacity release and polyester chain recovery also contributed. After years of anti-involution adjustments, the PTA and polyester sectors have seen substantial supply-demand optimization, providing a sustainable base for profit repair. Thus, Hengyi's growth is a dual-engine result of refining and chemical fibers.
The 'Oil-Coal-Cloth' Triangle: Strategic Depth Beyond Single Crude Dependency
More noteworthy are three major projects underway that sketch a radically different future industry map. Brunei Phase II optimizes design capacity to 12 million tons/year, targeting completion by end-2028, bringing total Brunei capacity to 20 million tons/year—the only overseas capacity increment among recent private mega-refiners.
Xinjiang coal-to-EG project plans 2.4 million tons/year of high-quality fiber-grade EG, expected to start production in H1 2028. This expands Hengyi's feedstock sources from single crude to coal, effectively hedging oil price volatility. The Jingzhou circular new materials project uses waste textiles as feedstock instead of crude, building a 300,000-ton/year demonstration facility with an 18-month construction period, aligning with national 'dual-carbon' and waste textile recycling policies.
After completion, Hengyi will form a unique 'oil-coal-cloth' parallel industry structure. The synergy of multiple feedstock routes enhances profit stability across the chain—when one route faces pressure, others provide buffers, creating a moat hard for traditional single-refinery firms to replicate.
Sustainability of High Growth: Four Variables Defining the Ceiling
The market's key question: Can the 23-fold growth continue? In the short term, Southeast Asian fuel supply-demand tightness is unlikely to reverse quickly, supporting Brunei's high profitability for the year; PTA and polyester sector capacity has substantially optimized, making profit repair sustainable; and nylon project ramp-up adds incremental gains. The judgment that the full-year profit center will permanently shift upward has strong logical support.
However, four risks are critical:
- **Crude oil price volatility**: A sharp drop would trigger inventory write-downs and narrow cracking spreads, directly eroding refining profits.
- **Project execution uncertainty**: Brunei Phase II and coal-to-EG projects are capital-intensive with long construction periods, facing risks of delays or funding strains.
- **Geopolitical and policy risks**: Core refining capacity concentrated in a single country (Brunei) exposes it to policy changes or geopolitical shifts that could impact cost advantages and feedstock supply stability.
- **Downstream demand transmission**: If textile end-demand disappoints, polyester profit repair could be disrupted.
Valuation Rerating: From Cyclical to Growth Stock Logic
Hengyi's H1 23-fold net profit growth is not a random cyclical pulse but a concentrated release of years of global layout, full-chain deep cultivation, and R&D accumulation. Short-term, industry upcycle plus capacity release provides strong certainty for high growth; medium-to-long term, as the three projects land sequentially, the company will upgrade from a 'refining-chemical fiber leader' to an 'oil-coal-cloth integrated new materials enterprise'.
For buyers and downstream firms, Hengyi's expansion means structural changes in future PTA, polyester, and nylon feedstock supply. Brunei Phase II's PX capacity increment will directly impact domestic PTA pricing logic; coal-to-EG project startup may lower EG marginal cost, reshaping the polyester chain cost curve.
