What Is Londian Wason New Energy Tech Inc.? How to Buy and Short It on MEXC

What Londian Wason New Energy Tech Actually Does

Copper foil is the least glamorous component in a lithium-ion cell and one of the few that cannot be engineered away. Every cell needs a current collector on the anode side, and that collector is a sheet of electrolytic copper rolled to a few thousandths of a millimetre. Londian Wason makes that sheet. That is the business.

The company grew out of a copper foil plant founded in 2001 in Lingbao, Henan, and now runs six production sites across China with roughly 180,000 tonnes a year of designed capacity, plus one under construction in Malaysia. Headquarters is in Shenzhen. According to Frost & Sullivan, cited in the company's F-1 registration statement, it was the world's largest supplier of lithium-ion battery copper foil by sales volume in 2025, with 7.6% of the global market.

Thinner foil is worth more. Every micron stripped out is a micron handed back to active material, so cell makers push suppliers down the gauge curve — from 8μm to 6μm, now toward 4μm. Londian Wason was the first Chinese producer to reach volume manufacturing of 6μm high-strength battery foil, and reports 634 patents held in China as of the end of 2025. A second line produces circuit-grade foil in RTF and HVLP specifications for high-speed printed circuit boards, which is where AI server demand turns up in a foil order book. A third makes flexible copper-clad laminate.

The customer list is the industry: LG Energy Solution, Samsung SDI, SK On, Panasonic, ATL, CATL and BYD. SK Group of South Korea holds about 29.5%.

What is easy to miss is that copper foil producers do not really sell copper. They buy cathode copper at market price, pass that cost straight through to the customer, and earn a processing fee per tonne for converting it into foil. The income statement tracks the processing fee, not the copper price — and fees fell hard when the industry added capacity faster than battery demand absorbed it. The 2025 accounts show the result: revenue of about RMB 10.9 billion, a gross margin of 6.6%, and net income of roughly RMB 20 million. A net margin near 0.2% on eleven billion yuan of turnover. The year before, it lost money outright. More sits on the company's official website.

Why Traders Are Watching FOIL

The interesting property of a company earning 0.2% net margin is what happens when the fee moves. In the first quarter of 2026, revenue more than doubled year on year to about RMB 4.1 billion, and the bottom line swung from a loss of roughly RMB 68 million to a profit of about RMB 135 million. Nothing structural changed in three months. Processing fees recovered, mix improved, and a business sitting flat on breakeven was suddenly earning. The arithmetic runs in reverse just as fast.

That profile — enormous revenue, wafer-thin margin, violent operating leverage — is rare in listed battery exposure. Most of what trades publicly is cell manufacturers or lithium miners. Copper foil sits between them, in a layer that behaves like a toll on volume rather than a bet on a commodity price. Anyone wanting EV and grid-storage build-out exposure without lithium price risk has few liquid instruments.

Then there is access. China's battery supply chain has overwhelmingly listed in Shenzhen, Shanghai or Hong Kong. A New York listing is the exception — Beijing has spent recent years steering domestic champions toward listing closer to home, and the China Securities Regulatory Commission cleared very few US offerings in the year before Londian Wason received its overseas listing filing notice in December 2025. For anyone outside China, the scarcity is the point. The alternative route into this layer is A-shares, which most non-resident investors cannot buy directly.

Two more features cut both ways. Backing from SK Group alongside a customer list of the largest cell makers on earth is evidence that the foil qualifies at the top of the market; it is also concentration, because a few buyers account for most of the revenue. And the offering is small against the total share count, leaving a modest tradable float under a market capitalisation in the billions. Small floats move.

Trading FOIL on MEXC

FOILUSDT is a perpetual futures contract on MEXC that tracks a reference price for Londian Wason's US-listed stock, settled in USDT. Traders never hold, borrow, or deliver the underlying shares.

The contract trades around the clock, which is the practical reason to use it rather than the cash market: New York equity sessions cover a fraction of the day, and direct brokerage access to a US-listed Chinese issuer is not available in every jurisdiction.

For current contract specifications — leverage, margin mode, trading rules, and how the reference price and its unit are defined — see the FOILUSDT contract page.

How to Buy FOIL (Going Long)

Traders who expect Londian Wason's reference price to rise can open long exposure through the FOILUSDT perpetual futures contract. Six steps:

• 1. Fund your futures account. Transfer USDT from your spot wallet to your USDT-M futures account.
• 2. Open the FOILUSDT contract page. Search the ticker, or browse the futures market list.
• 3. Set your margin mode and leverage. The available options are shown on the contract page.
• 4. Choose your order type. A limit order sets your entry price and waits; a market order fills immediately at whatever the book offers.
• 5. Enter your position size. Read the sizing note below before settling on a number.
• 6. Click Open Long. Then set a take-profit and stop-loss on the open position.

Step 5 deserves more thought than the entry price. Leverage cuts both ways: the higher the multiple, the smaller the adverse move needed to wipe out the margin backing your position.

How to Short FOIL

Traders who expect the reference price to fall can take short exposure through the same contract. This does not involve borrowing or selling the underlying shares. The trader opens a short position in a derivative linked to Londian Wason's reference price.

• 1. Fund your futures account. Transfer USDT from your spot wallet to your USDT-M futures account.
• 2. Open the FOILUSDT contract page. Search the ticker, or browse the futures market list.
• 3. Set your margin mode and leverage. The available options are shown on the contract page.
• 4. Choose your order type. Limit to name your entry price, market to fill immediately.
• 5. Enter your position size. The same sizing logic applies in reverse.
• 6. Click Open Short. Then set a take-profit and stop-loss.

Two things behave differently on the short side. Funding payments flow between longs and shorts depending on whether the contract trades above or below its reference price, so an open short can earn or pay funding over time. And losses on a short have no natural ceiling, because there is no upper bound on how far a price can rise.

The specific hazard here is the float. A small offering against a large share count leaves few shares circulating, and thin floats squeeze hard when demand arrives — a reference price can travel a long way before a natural seller appears.

What Changes After Listing

Before a stock has a public market, its reference price is an indicative mark: an estimate of what the equity is worth, not a print off an order book. Once the ADSs trade on the New York Stock Exchange, two things change. The reference becomes a live quoted price with real depth behind it. And the contract inherits the NYSE session calendar, so the underlying stops moving overnight, at weekends and on US holidays while the perpetual keeps trading — which is where gaps come from. Newly listed US stocks carry no daily price limit.

Risks to Understand First

• Liquidity. Volume in a new contract can be thin: slippage, wide spreads, bad stop-loss fills.
• Price uncertainty. A reference price is an estimate, and venues can carry different marks.
• Gap risk. While the underlying market is closed, information accumulates with nowhere to go.
• Contract terms. Exchanges may adjust leverage tiers, margin requirements or position limits.
• Regional availability. Stock futures are restricted in some jurisdictions.
• A thin financial cushion. A 6.6% gross margin and near-zero net margin in 2025 leave little room to absorb a downturn. Operating cash flow was negative in 2024 and 2025, and the F-1 discloses a period of working capital deficiency that raised going-concern doubt until a major shareholder stepped in.
