Item 3.03 - Material Modification to Rights of Security Holders
As previously disclosed, on June 4, 2025, at the 2025 Annual Meeting of Stockholders of Quince Therapeutics, Inc. (the “Company”), the Company’s stockholders approved the implementation of a reverse stock split at a ratio of 1-for-10 with such reverse stock split to be effected at such time and date, as determined by the Company’s board of directors in its sole discretion (the “Reverse Stock Split”) and a form of certificate of amendment to the Company’s Amended and Restated Certificate of Incorporation (the “Certificate of Amendment”) to effect the Reverse Stock Split.
The Company’s board of directors approved the implementation of the Reverse Stock Split and on April 9, 2026, the Company filed the Certificate of Amendment with the Secretary of State of the State of Delaware, which will be effective at 11:59 pm Eastern Time on April 10, 2026. The Company’s shares of common stock will begin trading on a split-adjusted basis on the Nasdaq Global Select Market commencing upon market open on April 13, 2026. A copy of the Certificate of Amendment is attached hereto as Exhibit 3.1 and is incorporated herein by reference. This discussion is qualified in its entirety by reference to the full text of the Certificate of Amendment.
As a result of the Reverse Stock Split, every ten (10) shares of the Company’s issued and outstanding common stock will be automatically combined and converted into one (1) issued and outstanding share of common stock, par value $0.001 per share. The Reverse Stock Split will affect all of the Company’s stockholders uniformly and will not affect any stockholder’s percentage ownership interests in the Company except that stockholders who would have otherwise received fractional shares will receive cash in lieu of such fractional shares. The Reverse Stock Split will not modify the rights or preferences of the common stock.
Immediately after the Reverse Stock Split becomes effective, there will be approximately 16,300,795 shares of common stock issued and outstanding. The common shares will trade under a new CUSIP number, 22053A206 effective April 13, 2026, and continue to trade under the symbol “QNCX.” All stock options and warrants of the Company outstanding immediately prior to the Reverse Stock Split have been proportionally adjusted.
The Company has appointed its transfer agent, Equiniti Trust Company, LLC, to act as exchange agent for the Reverse Stock Split. Stockholders owning shares via a bank, broker or other nominee will have their positions automatically adjusted to reflect the Reverse Stock Split and will not be required to take further action in connection with the Reverse Stock Split, subject to brokers’ particular processes.
