Wanhua Chemical started a scheduled 60-day maintenance shutdown at its 1.20 million tons/year ethylene Phase II unit on October 10, 2026, according to ChemNet. The company said the planned outage should not materially affect overall production and operations, while the adjacent Phase I unit continues normal production.

Three dated operating milestones

On August 25, 2026, Wanhua Chemical reported first-half revenue of CNY 119.32 billion and net profit of CNY 10.06 billion, according to Investing.com. On September 28, 2026, the company held its half-year performance briefing after reporting the same revenue and profit figures, as Sina Finance reported. On October 9, 2026, the company disclosed the ethylene maintenance plan, with the unit scheduled to stop from October 10 for 60 days, according to ChemNet.

What does the outage mean for earnings?

The latest earnings provide a sizable buffer before the shutdown: first-half revenue grew 31.30 percent year over year, while net profit rose 64.30 percent. Second-quarter revenue reached CNY 65.26 billion, up 36.40 percent year over year, and quarterly net profit reached CNY 6.35 billion, up 108.70 percent, according to Futu. The comparison matters because the maintenance affects one ethylene unit rather than the entire Yantai complex.

Stock valuation stays tied to chemicals

Wanhua Chemical had a market capitalization of CNY 208.8 billion on October 13, 2026. Its 52-week range was CNY 60.60 to CNY 97.00, putting operating execution and product pricing at the center of the stock narrative while the planned outage runs its course.
