Shanghai PRET Composites is one of China's leading independent compounders of modified engineering plastics for the automotive industry, a pioneer in liquid crystal polymer (LCP) materials, and — since its 2022 acquisition of Jiangsu Highstar (海四达电源) — a mid-tier lithium-ion and sodium-ion battery manufacturer. The company describes its model as "new materials + new energy" dual-engine growth. Its modified-materials business supplies polypropylene, ABS/PC alloys, polyamides and specialty polymers (PEEK, PPS, PPA, PPO) to BMW, Mercedes-Benz, Audi, VW, GM, Ford, BYD, Geely, Chery, Leapmotor, Seres, NIO, Li Auto and XPeng from 12 plants (four under construction) with 560,000 t/yr capacity, targeting 1 Mt long-term. Its ICT segment is described by the company as the world's only producer with full LCP resin-compound-film-fibre capability at scale. The battery arm (15.32 GWh lithium plus sodium capacity) serves power tools (TTI, Stanley Black & Decker, Bosch) and energy storage (State Grid, China Mobile, China Tower). FY2025 revenue was CNY 9.90 bn; net profit attributable CNY 367 m.

### Company's own description (FY2025 Annual Report summary, published 24 April 2026)
The company states that it is principally engaged in the research, development, production, sale and service of polymer new materials and their composites, as well as lithium-ion batteries, sodium-ion batteries, solid-state batteries and system integration. Its business is organised into three directions: Modified Materials, ICT Materials and New Energy.
**Modified Materials:** general-purpose materials (modified PP, ABS, PS, PE), engineering materials (modified PA, PC/ABS, polyesters) and specialty engineering materials (modified PEEK, PPS, PPA, PPO), applied to automotive parts, electrical and electronic appliances, aerospace, two-wheelers, power and energy-storage systems, low-altitude aviation and robotics.
**ICT Materials:** built around the synthesis and application of liquid crystal polymer (LCP) — LCP resin, LCP compounds, LCP film and LCP fibre — used in high-frequency/high-speed connectors, cooling fans, electronic packaging (compounds), flexible printed circuit substrates and earphone diaphragms (film), and high-speed PCB substrates and cables/ropes (fibre).
**New Energy:** ternary (NCM) lithium-ion, lithium iron phosphate (LFP), sodium-ion and solid-state batteries and systems for power tools, smart home appliances, telecoms, energy storage, two-wheelers, low-altitude aviation, robotics, rail transit, aerospace, data centres, construction machinery and electric vessels.
### Independent characterisation
PRET is best understood as a cyclical, spread-driven B2B materials converter bolted to a capital-intensive, low-margin battery manufacturer, with an option-value technology franchise (LCP) that is still small in revenue terms.
1. **Modified plastics (≈64–67% of revenue, the profit engine).** PRET buys commodity and engineering resins (chiefly polypropylene, ABS, PC, PA) and compounds them with fillers, glass/carbon fibre, flame retardants, elastomers and additives into application-specific grades qualified by automotive OEMs and Tier-1s. Economics are a "processing spread": selling prices are negotiated with customers against resin-price trends, so profitability compresses when crude/petrochemical prices rise quickly (pass-through lags) and expands when they fall. This was explicitly the reason given for the H1 2026 profit collapse (H1 2026 Performance Forecast, July 2026). The moat is OEM qualification (multi-year material approvals by part number), colour-matching and low-VOC know-how, and a global plant network following Chinese OEMs abroad (Thailand, Mexico, US).
2. **Batteries (≈33% of FY2025 revenue, rising to ≈45% in H1 2026; marginal profit).** Through Jiangsu Highstar (87.04% owned), PRET makes cylindrical cells (18650/21700/46-series, full-tab) for cordless power tools, garden tools, appliances and battery backup units (BBU), and prismatic LFP cells (100Ah, 314Ah, 392Ah) for stationary storage, plus sodium-ion cells (NFPP polyanion chemistry). Highstar lost CNY 54.5 m in FY2025 on revenue of CNY 3.29 bn (FY2025 guarantee notice), and battery gross margin was only 6.92% in H1 2026 (CICC, 2 Sep 2026).
3. **ICT/LCP (small, high-optionality).** In 2025 PRET's LCP film entered volume supply for flexible-circuit antennas in a leading consumer-electronics customer's handsets — which the company calls a 0-to-1 domestic breakthrough — and LCP fibre entered a domestic low-earth-orbit satellite supply chain (flexible solar wings) in April 2025 (investor-relations record, 25 Dec 2025). Segment revenue is not separately disclosed in sources reviewed.
### Revenue model
| Revenue model element | Assessment |
|---|---|
