How Nantong Jianghai Capacitor makes money
It makes money by manufacturing capacitors and related materials and selling them to equipment makers in China and abroad. Export sales add to its domestic revenue.
What Nantong Jianghai Capacitor does
Nantong Jianghai Capacitor, founded in 1958 and based in Nantong, China, researches, develops, makes, and sells capacitors along with the materials and instruments used to make them. It works across three technologies: aluminum electrolytic capacitors (snap-in, screw terminal, radial, axial, polymer, and polymer hybrid), film capacitors (DC-link, snubber, AC and filter, pulse, and general purpose), and super capacitors (EDLC, lithium-ion capacitors, and modules). Its parts go into consumer electronics, automotive, traction, renewable energy, healthcare, and energy recuperation equipment. That puts the company in supply chains tied to electrification and clean power. It sells in China and exports internationally.

What is Nantong Jianghai Capacitor worth?
On an owner-earnings DCF, Nantong Jianghai Capacitor's most-likely value is about ¥12 versus a recent price near ¥45 (287% above fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~¥5) with a margin of safety — so the honest verdict here is “Stretched — richly priced.” Fair value earns its keep only at the extremes, not in the wide middle.
Today's $45 is above even the optimistic Bull case ($19) — the market expects faster, longer growth than modeled here. Expensive unless that extra growth actually shows up.
Analysis, not advice. Fair value is a margin-of-safety estimate from a deterministic owner-earnings DCF, not a price target or recommendation. See the full breakdown →
