Company Overview
GEM Co., Ltd. (格林美股份有限公司) has transformed from a small recycling startup into China's largest urban mining company and one of the world's most important players in the EV battery supply chain. Founded in 2001 by Professor Xu Kaihua, the company pioneered the concept of "urban mining" in China — extracting valuable metals from electronic waste and spent batteries rather than traditional mining.
Today, GEM processes over 300,000 tons of waste batteries annually, recovering critical materials including cobalt, nickel, lithium, and manganese. The company supplies precursor materials to major battery manufacturers including CATL, Samsung SDI, and LG Energy Solution, making it a crucial upstream player in the global EV ecosystem.
Strategic Position in the Battery Supply Chain
GEM occupies a unique position in the battery supply chain, operating at both ends: recycling spent batteries and producing precursor materials for new ones. This circular model provides several strategic advantages:
- Resource security: By recovering materials from waste, GEM reduces dependence on primary mining and volatile commodity markets.
- Cost advantage: Recycled materials often cost 20-30% less than mined equivalents, improving margin stability.
- Environmental compliance:As ESG requirements tighten globally, GEM's recycling-based model aligns with sustainability mandates from automakers and regulators.
- Customer lock-in: GEM has established long-term supply agreements with major battery makers, including a 10-year deal with Samsung SDI worth over $10 billion.
Key Business Segments
Battery Materials (60% of Revenue)
Production of NCM (nickel-cobalt-manganese) precursors and cathode materials for lithium-ion batteries. GEM is a top-5 global supplier of battery-grade cobalt and nickel products.
Urban Mining & Recycling (30% of Revenue)
Processing of spent batteries, electronic waste, and industrial scrap to recover cobalt, nickel, copper, and rare earth elements. Operating 16 recycling facilities across China.
International Operations (10% of Revenue)
Overseas mining interests in Indonesia (nickel), South Africa (cobalt), and the DRC. GEM has invested over $1.5 billion in international resource projects since 2018.
Policy Implications & Geopolitical Context
GEM's dominance in battery recycling reflects broader Chinese industrial policy. The company has benefited from government support through preferential loans, tax incentives, and policies requiring battery recycling. The 2018 "Extended Producer Responsibility" regulations, which require automakers to ensure battery recycling, directly channeled business to companies like GEM.
For Western policymakers concerned about supply chain dependencies, GEM represents both a challenge and a model. The company's success demonstrates that urban mining can be commercially viable at scale — a potential template for building domestic recycling capacity in the US and Europe. At the same time, GEM's market position means that even recycled battery materials often flow through Chinese intermediaries.
Investment & Financial Performance
GEM has delivered compound annual revenue growth of 35% over the past five years, driven by expanding battery materials capacity and rising recycling volumes. The company invested RMB 12 billion ($1.7B) in capacity expansion during 2022-2024, including new precursor plants in Fujian and Indonesia.
Key financial metrics (FY2024): Revenue of RMB 28.5 billion ($4.0B), gross margin of 18.2%, and net profit of RMB 1.8 billion ($250M). The company trades at approximately 25x forward earnings, a premium to traditional materials companies reflecting its exposure to the EV growth story.
