Londian Wason New Energy Tech Inc. (NYSE: FOIL) priced a New York initial public offering, watched its shares trade for days on a when-issued basis, then had them halted by the exchange before settlement because complaints about its pre-listing restructuring were unresolved. The Shenzhen maker of electrolytic copper foil announced on August 19, 2026 that the offering had closed and that the New York Stock Exchange had lifted the halt.
The deal itself was conventional. A final prospectus filed under Rule 424(b)(4) on August 14, 2026 covers 4,285,714 American depositary shares at US$22.00 each, for a public offering price total of US$94,285,708. Each ADS represents five ordinary shares of a par value of US$0.00001, and the underwriters may buy up to 642,857 additional ADSs within 30 days to cover over-allotments. Underwriting discounts and commissions run to US$1.54 per ADS. The New York Stock Exchange certified the ADSs for listing and registration on August 11, 2026.
Where the money is going
Londian Wason estimated net proceeds of approximately US$77.0 million, or approximately US$90.2 million with the over-allotment option exercised in full, after underwriting discounts, commissions and estimated expenses. The prospectus allocates approximately 45%, or US$34.7 million, to global production expansion and upgrades, approximately 40%, or US$30.8 million, to research and development on advanced technologies, and approximately 15%, or US$11.6 million, to general corporate purposes.
The business behind that plan turned in 2025. Revenue rose 24.9% from RMB8,762.3 million in 2024 to RMB10,942.1 million, which the prospectus converts to US$1,564.7 million. The company recorded net income of RMB20.3 million, or US$2.9 million, in 2025 against a net loss of RMB292.9 million in 2024, moving the net margin from minus 3.3% to 0.2%. Operating activities still consumed cash in both years, RMB126.0 million in 2024 and RMB81.3 million in 2025. Citing the Frost and Sullivan Report, the filing describes the company as the world’s largest supplier of copper foil for lithium-ion batteries by sales volume in 2025, with a global market share of 7.6% on approximately 111,985 metric tons, up 24.4% from 90,034 metric tons in 2024.
The most recent quarter shows higher revenue and a swing to net income. Revenue for the three months ended March 31, 2026 was RMB4,072.7 million, or US$582.4 million, up 113.7% from RMB1,905.7 million a year earlier. Sales volume of lithium-ion battery copper foil rose 78.3% to 35,746 metric tons from 20,047 metric tons, and the average selling price rose from RMB83.8/kg to RMB105.5/kg. Net income was RMB134.5 million, or US$19.2 million, against a net loss of RMB68.4 million a year earlier. Part of that is copper: the prospectus cites Frost and Sullivan for a 29.0% rise in the average copper price in China, from RMB76,173.7 per metric ton to RMB98,252.2 per metric ton over the same comparison.
The halt
Registration statements on Form F-1 became effective on August 11, 2026, and the ADSs began trading on the exchange on August 12, 2026 on a when-issued basis, subject to delivery of the ADSs at closing. On August 17, 2026 the company told the exchange the closing would be delayed, and the exchange halted trading.
Londian Wason gave a reason in the same filing. It said it had not yet resolved certain complaints and related regulatory implications concerning its restructuring undertaken prior to the offering, including matters relating to transactions involving its controlling shareholders and the legal and regulatory compliance of those shareholders. Resolving them with the relevant parties would push the closing past the anticipated date of on or about August 17, 2026. The company said the complaints do not relate to its business operations or financial condition. A second filing dated August 19, 2026 set a new expected closing on or about that date, as agreed with the representatives of the underwriters, and a third confirmed the closing and the resumption of trading.
Analysis: what a when-issued halt actually risks
The sequence matters more than the outcome. Under Rule 424, a prospectus disclosing the offering price must reach the Commission no later than the second business day after the price is set or the document is first used. That timing is why a listing can begin trading before the underwriters deliver stock: pricing, effectiveness and the start of when-issued dealing all precede settlement. Buyers in that window hold contracts for securities that do not yet exist in their accounts. If a closing fails rather than slips, those trades have to be unwound, which is the reason an exchange halts rather than letting the market keep pricing an uncertain delivery.
Londian Wason’s disclosure states what the complaints are not. It says they concern the restructuring and the controlling shareholders, not operations or financial condition. The prospectus describes that restructuring in detail. The Cayman holding company was incorporated in September 2022, a Hong Kong intermediary and a wholly foreign owned enterprise followed, and the operating equity was moved out of Shenzhen Londian Wason Holding Group Co., Ltd. The prospectus records the related party balances that followed: amounts due from principal shareholders of RMB3,259.4 million as of December 31, 2022, representing subscription receivable, a further RMB257.8 million due from Shenzhen Londian, and amounts due to related parties of RMB5,486.0 million as of the same date for acquiring equity interests. The prospectus states the substantial majority of that payable had been settled with nil outstanding as of December 31, 2025.
What the filings do not establish is who complained, to which body, or on what legal basis. The company names no counterparty, no forum and no claim. That absence is the gap in the public record: the filings do not show what kind of proceeding, if any, the complaints belong to, and the company has not said. The prospectus records that the company completed its filing with the China Securities Regulatory Commission under the Trial Administrative Measures of Overseas Securities Offering and Listing by Domestic Enterprises, which took effect on March 31, 2023, and obtained the Notice of Filing for Overseas Offering and Listing on December 12, 2025. A completed CSRC filing is a procedural clearance for the offering, not a determination about shareholder conduct.
One inconsistency in the record is worth flagging. The August 17 trading halt announcement describes the offering as 4,285,714 ADSs representing 21,428,570 ordinary shares, the figure that also appears on the prospectus cover and that matches five ordinary shares per ADS. The two August 19 announcements describe the same offering as 4,285,714 ADSs representing 21,438,570 ordinary shares. The company has not explained the difference, and the closing announcement carries the higher number.
A reader following this would watch three things: whether any prospectus supplement or subsequent report identifies the complainants or a settlement, whether the over-allotment option is exercised inside its 30 day window, and whether the share count reconciles in the first annual report on Form 20-F. The prospectus shows 390,792,185 ordinary shares outstanding after the offering, or 394,006,470 if the option is exercised in full, so that reconciliation will be visible.
