On April 22, 2026, Cue Biopharma, Inc. (the “Company”) filed a Certificate of Amendment to the Company’s Amended and Restated Certificate of Incorporation, as amended (the “Certificate of Amendment”), with the Secretary of State of the State of Delaware, which will effect, as of 5:00 p.m. Eastern Time, on April 23, 2026 (the “Effective Time”), a 1-for-30 reverse stock split (the “Reverse Stock Split”) of the issued and outstanding shares of the Company’s common stock, $0.001 par value per share (the “Common Stock”).

The Reverse Stock Split is intended, among other things, to bring the Company into compliance with the minimum bid price requirement for continued listing on the Nasdaq Capital Market, as previously reported in the Company’s definitive proxy statement for the Company’s 2026 annual meeting of stockholders held on April 13, 2026, as filed with the Securities and Exchange Commission on March 16, 2026 (as supplemented, the “Proxy Statement”).

At the Effective Time, every thirty shares of issued and outstanding Common Stock will be automatically reclassified and combined into one share of Common Stock. No fractional shares will be issued in connection with the Reverse Stock Split. Stockholders who would otherwise be entitled to a fractional share of Common Stock are instead entitled to receive a cash payment in lieu of such fractional shares.

The Reverse Stock Split will not change the number of authorized shares of Common Stock or the par value of the Common Stock. All outstanding stock options and warrants to purchase Common Stock will be adjusted to proportionately reduce the number of shares of Common Stock issuable upon exercise of such stock options and warrants and to proportionately increase the exercise price of such stock options and warrants, pursuant to the terms of each security and as described in the Proxy Statement. In addition, the total number of shares of Common Stock available for future grants under the Company’s equity incentive plans will be adjusted and proportionately decreased, in accordance with the respective terms of such plans and as described in the Proxy Statement.

The Common Stock is expected to begin trading on a post-Reverse Stock Split basis at the market open on April 24, 2026 under the Company’s existing trading symbol “CUE”. The new CUSIP number for the Common Stock following the Reverse Stock Split is 22978P205.

The foregoing description of the Certificate of Amendment does not purport to be complete and is qualified in its entirety by reference to the complete text of the Certificate of Amendment, a copy of which is attached hereto as Exhibit 3.1 and is incorporated herein by reference.

Cautionary Note Regarding Forward Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements include, but are not limited to, those regarding: the Company’s ability to comply with the continued listing standards of the Nasdaq Capital Market and the timing and effectiveness of the Reverse Stock Split. Forward-looking statements, which are based on certain assumptions and describe the company’s future plans, strategies and expectations, can generally be identified by the use of forward-looking terms such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “goal,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” “seek,” “strategy,” “future,” “vision,” “should,” “target,” “will,” “would,” “likely” or other comparable terms, although not all forward-looking statements contain these identifying words.

Any forward-looking statements are based on management’s current expectations of future events and are subject to a number of risks and uncertainties that could cause actual results to differ materially and adversely from those set forth in, or implied by, such forward-looking statements. These risks and uncertainties include, but are not limited to, risks associated with the Company’s ability to maintain its collaboration with ImmunoScape; the Company’s limited operating history, limited cash and a history of losses; the Company’s ability to achieve profitability; the Company’s ability to obtain adequate financing to fund its business operations in the future; the Company’s ability to successfully remediate its current “going concern” determination that it does not have sufficient capital on hand to continue operations beyond the next twelve months; the Company’s reliance on licensors, collaborators, contract research organizations, suppliers and other business partners; potential setbacks in its research and development efforts including negative or inconclusive results from its preclinical studies or clinical trials; and the Company’s ability to replicate in later clinical trials positive results found in preclinical studies and early-stage clinical trials of its product candidates. For a discussion of other risks and uncertainties, and other important factors, any of which could cause the Company’s actual results to differ from those contained in the forward-looking statements, see the “Risk Factors” section in the Company’s most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q filed with the SEC. In addition, the forward-looking statements included in this Current Report on Form 8-K represent the Company’s views as of the date hereof and should not be relied upon as representing the Company’s views as of any date subsequent to the date hereof. The Company anticipates that subsequent events and developments will cause the Company’s views to change. However, while the Company may elect to update these forward-looking statements at some point in the future, the Company specifically disclaims any obligation to do so.
