Londian Wason New Energy Tech (FOIL) Stock Price & How to Invest

Londian Wason New Energy Tech was founded in 2001 and manufactures electrolytic copper foil, the very thin copper sheet (commonly 4.5 to 8 microns) that serves as the anode current collector inside a lithium-ion cell. It also makes electric energy meters and energy storage systems, which give it a second and third revenue stream outside battery materials. Frost & Sullivan ranked it the world's largest supplier of lithium-ion battery copper foil by sales volume in 2025, with roughly 7.6 percent global share, and its disclosed customer list includes CATL, BYD, LG Energy Solution, Samsung SDI and Panasonic. The group restructured under a Cayman Islands holding company in September 2022 to enable an offshore listing; the operating subsidiaries, plants and people remain in China.

The listing itself is very recent. Londian Wason priced an upsized offering of roughly 4.3 million ADSs at $22.00 on August 11, 2026, raising about $94.3 million gross, and began trading on the NYSE on August 12, opening at $26.00. Around $24 in mid-August 2026 the market capitalisation is roughly $1.87 billion. One number on this company is widely misread: FY2025 revenue of RMB 10.942 billion is frequently carried onto screens as a dollar figure, which makes the stock look like it trades at 0.17 times sales. In dollars the revenue is closer to $1.57 billion, so the ratio is nearer 1.2 times. What that revenue does not produce is profit. FY2025 net income was RMB 20.3 million (about $2.9 million), a margin under a quarter of one percent, against adjusted EBITDA of RMB 869 million (about $124 million). That gap is the fingerprint of a capital-heavy manufacturer carrying heavy depreciation and interest, operating in a material whose selling price is largely set by the copper market plus a processing fee.

The dominant risk is that the profit is not there yet: FY2025 net income of about $2.9 million on about $1.57 billion of revenue leaves no cushion, and a modest move in processing fees or copper costs can swing the company between profit and loss. The sector backdrop is genuinely difficult, with structural overcapacity in low and mid grade foil and peer Nuode New Materials reporting a net loss of CNY 159 million in a recent half year. The float is roughly 4.6 percent of shares outstanding, so ordinary trade sizes can move the price sharply and the eventual lockup expiry adds supply against that small base. Founder Guanran Wang controls about 51.7 percent of the voting power, which leaves minority ADS holders with limited influence over strategy or capital allocation. As a Cayman holding company over PRC operating subsidiaries, FOIL carries the standard China ADR exposures, including PRC regulatory intervention, restrictions on moving cash out of the operating entities, and the audit-inspection regime under the Holding Foreign Companies Accountable Act.

We give no verdict on Londian Wason New Energy Tech. Both cases are real, which is why the question is contested at all, so here is the strongest version of each.

The case for buying. Volume leadership in a consolidating material. Being the largest lithium-ion battery copper foil supplier by volume matters in a business where fixed costs dominate and utilisation drives unit economics.

The case against. The dominant risk is that the profit is not there yet: FY2025 net income of about $2.9 million on about $1.57 billion of revenue leaves no cushion, and a modest move in processing fees or copper costs can swing the company between profit and loss.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Londian Wason New Energy Tech's investor relations page or your broker.

• Revenue (FY2025): ~$1.57B (RMB 10.94B)
• Revenue growth (FY2024 to FY2025): ~25%
• Net income (FY2025): ~$2.9M (RMB 20.3M)
• Adjusted EBITDA (FY2025): ~$124M (RMB 869M)
• Market cap: ~$1.87B
• Price to sales: ~1.2x

The single most common error on this ticker is reading RMB 10.94 billion of FY2025 revenue as dollars, which produces an apparent 0.17 times sales and makes the stock look absurdly cheap; converted properly the multiple is around 1.2 times. Earnings-based multiples are close to meaningless here because net income is about $2.9 million, so a price to earnings figure runs into the hundreds and tells you nothing useful. Adjusted EBITDA of roughly $124 million is the more workable anchor, putting market cap at about 15 times that figure before any adjustment for the debt a foil manufacturer of this size typically carries.

Other names that sit close to FOIL: same theme, named as a direct competitor, or held beside it in the same funds. Each entry says which. Worth a look if you are thinking about diversification within a thesis rather than concentration on one ticker.

There are three common ways to get FOIL exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic portfolio, so FOIL sits alongside other stocks that express the same thesis.

Walnut takes the portfolio route. Describe a thesis where FOIL fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.

FOIL is exposure to the world's largest lithium-ion battery copper foil supplier by volume, priced as a thin-float Chinese ADS that converts about $1.6 billion of sales into single-digit millions of net income.

Whether FOIL is worth buying today depends more on your time horizon and what you already hold than on any single call. We walk through valuation, what would have to go right, and the risks in is FOIL a buy or a sell?, and where the stock could go from here in the FOIL stock forecast.
