Breaking Down Sinopec Shanghai Petrochemical Company Limited Financial Health: Key Insights for Investors

From its roots in 1972 to becoming a pillar of China's petrochemical sector, Sinopec Shanghai Petrochemical (ticker 0338.HK) blends state-backed scale and market-facing strategy: in 2023 it commissioned a 1 million tonne-per-year SBC plant in Hainan, helping Sinopec lead global SBC output, while in 2024 it processed 252.3 million metric tons of crude (down 2.03% year-on-year) amid soft fuel demand; corporate shifts include the September 2022 NYSE ADS delisting and a March 2024 move to deregister under the U.S. Securities Exchange Act, and operational renewal is underwritten by a planned 21.31 billion yuan (≈$2.91 billion) upgrade announced January 2025 that will replace 18 refining units to preserve capacity, even as H1 2025 reported a net loss of 462.1 million yuan ($64.4 million) and trailing‑12‑month revenue fell 10.24% through September 30, 2025; as a Sinopec Group subsidiary supervised by SASAC, with listings in Hong Kong and Shanghai and roughly 6,715 employees, the company operates an integrated refinery-petrochemical complex producing gasoline, diesel, naphtha, ethylene, polyethylene, polypropylene, resins and fibers while pursuing carbon fiber expansion and environmental upgrades to navigate market headwinds and diversify revenue streams.
