Quince SEC Filings

Quince Therapeutics (QNCX) filed an 8-K under Regulation FD to correct an Investor Day statement. The company removed Slide 57 and the related video from its October 2, 2025 Virtual Investor Day and advised investors not to rely on the slide’s claim that IntraBio’s N-acetyl-L-leucine (NALL) “failed Phase 2 A-T study across all endpoints.”

Quince clarified its statement drew from a European Journal of Paediatric Neurology article describing a single-site study in ataxia-telangiectasia, which reported no significant improvements in ataxia symptoms or motor function, and was not the multi-site IntraBio Phase 2 Study.

Quince Therapeutics (QNCX) filed a prospectus supplement for an at‑the‑market offering of up to $75,000,000 of common stock under its Controlled Equity Offering Sales Agreement with Cantor Fitzgerald & Co. and H.C. Wainwright & Co., LLC.

The company states it is currently no longer subject to the offering limits of General Instruction I.B.6. of Form S-3; if it becomes subject again, it will file another supplement.

QNCX common stock trades on Nasdaq under “QNCX.” The closing price was $1.93 on October 16, 2025.

The company reported consolidated assets of $117.2 million, liabilities of $105.5 million, and stockholders' equity of $11.7 million as of June 30, 2025.

Operating results show a continuing loss: $16.0 million net loss for the quarter and $31.1 million for the six months ended June 30, 2025, driven by higher R&D spending ($14.7 million for six months) and other non-cash fair value adjustments. The balance sheet includes €10.0 million ($11.7M) outstanding on an EIB loan, contingent consideration of $59.1 million, and warrant liabilities of $15.1 million. Management concluded that substantial doubt exists about the company’s ability to continue as a going concern within one year and notes the need for additional financing despite recent capital raises totaling approximately $14.4 million from a June 2025 private placement and ATM activity.
