Northann Corp. trading halted, auditor resigns, CEO steps down as chairman

What happened

Northann Corp. (NYSE American: NCL), a plastics products manufacturer based in Fort Lawn, South Carolina, disclosed in an SEC filing dated August 10, 2026, that trading of its common stock has been halted on the NYSE American since June 25, 2026, and the halt remains in place.

The company's independent auditor, LAO Professionals, resigned on June 8, 2026. In a letter to the company, the auditor said the 2025 annual report (Form 10-K) was filed without its knowledge or consent, and that it had not completed its audit or formed an opinion on the financial statements as of the time the report was filed.

The company said investors should not rely on its financial statements for the years ended December 31, 2024 and 2025, and that it plans to hire a new independent auditor to re-audit those periods.

CEO and President Lin Li resigned as Chairman of the Board on August 10, 2026, but continues as CEO and President. Director Umesh Patel resigned in April 2026, citing concerns about unmet commitments.

Background

Northann Corp. makes plastic products and trades on the NYSE American under the ticker NCL. The company is an 'emerging growth company' under SEC rules, which allows it to phase in certain reporting requirements.

The trading halt was initiated by the exchange after it learned the company may have filed its 2025 annual report without the auditor's approval or consent. The company said it is investigating the circumstances and has formed an Oversight Committee of the board to oversee the review.

The auditor's resignation letter, sent June 8, 2026, said the audit report dated April 25, 2026, that appeared in the 2025 10-K was issued without its authorization. The auditor stated it 'expressly disclaimed and rejected' any audit report attributed to it.

What this means

This 8-K filing combines several required disclosures. Item 3.01 notifies investors of a delisting risk or failure to meet listing standards. Item 4.01 discloses a change in the certifying accountant. Item 4.02 is a non-reliance notice, telling investors not to trust previously issued financial statements. Item 5.02 covers director or officer changes.

A trading halt means the exchange has suspended trading in the stock, often while it reviews whether the company meets listing standards. The halt is still in effect, and the company said it cannot predict when or if the exchange will lift it or start delisting proceedings.

An auditor resignation is a serious red flag for investors. The company's conclusion that the 2024 and 2025 financial statements are unreliable means those numbers cannot be used as a basis for investment decisions until a new audit is completed.

The company says it is looking for a new independent audit firm to redo the audits for 2024 and 2025. Until that happens, the company remains without a current, reliable audit opinion, which is normally required for continued listing on a major exchange.

The board changes, including CEO Lin Li stepping down as chairman and the creation of an Oversight Committee, are attempts to strengthen governance in response to these problems. Director Patel's resignation adds to the governance turmoil.
