**Item 3.03 Material Modification to Rights of Security Holders.**

To the extent required by Item 3.03 of Form 8-K, the information contained in Item 5.03 of this Current Report on Form 8-K (the ***"Report"***) is incorporated herein by reference.

**Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.**

As previously disclosed, on February 24, 2026, at the 2026 Annual Meeting of Stockholders of Decoy Therapeutics Inc. (the ***"Company"***), the stockholders approved a proposal to amend the Company's Amended and Restated Certificate of Incorporation, as amended (***"Certificate of Incorporation"***), to effect a reverse split of the Company's outstanding common stock, par value $0.0001 (***"Common Stock"***), at a ratio in the range of 1-for-4 to 1-for-15, to be determined at the discretion of the Company's Board of Directors (the ***"Board"***), whereby each outstanding 4 to 15 shares would be combined, converted and changed into one share of Common Stock, to enable the Company to comply with The Nasdaq Capital Market's (***"Nasdaq"***) continued listing requirements.

On February 25, 2026, the Board approved a 1-for-12 reverse stock split of the Company's issued and outstanding shares of Common Stock (the ***"Reverse Stock Split"***), effective March 6, 2026. On March 5, 2026, the Company filed with the Secretary of State of the State of Delaware a Certificate of Amendment to its Certificate of Incorporation (the ***"Certificate of Amendment"***) to effect the Reverse Stock Split. The Reverse Stock Split will become effective as of 5:00 p.m. Eastern Time on March 6, 2026 (the ***"Effective Time"***), and the Common Stock is expected to begin trading on a split-adjusted basis when Nasdaq opens on March 9, 2026.

When the Reverse Stock Split becomes effective, every 12 shares of the Company's issued and outstanding Common Stock will automatically be combined, converted and changed into one share of Common Stock, without any change in the number of authorized shares or the par value per share. In addition, a proportionate adjustment will be made to the per share exercise price and the number of shares issuable upon the exercise of all outstanding stock options, restricted stock units and warrants to purchase shares of Common Stock, as applicable, and the number of shares reserved for issuance pursuant to the Company's equity incentive compensation plans. Any fractional share of Common Stock that would be created as a result of the Reverse Stock Split will be rounded down to the next whole share and the stockholder will receive cash equal to the market value of the fractional share, determined by multiplying such fraction by the closing sales price of the Common Stock as reported on Nasdaq on the last trading day before the Reverse Stock Split becomes effective (on a split-adjusted basis). The number of authorized shares of the Company's common stock will remain at 100 million, while the number of outstanding shares will be reduced from approximately 6.38 million to approximately 532,000.

The Common Stock will continue to trade on Nasdaq under the symbol "DCOY." The new CUSIP number for the Common Stock following the Reverse Stock Split will be 79400X602.

Equiniti Trust Company, LLC, the Company's transfer agent, will act as the exchange agent for the Reverse Stock Split.

For more information about the Reverse Stock Split, see the Company's Definitive Proxy Statement on Schedule 14A, which was filed with the Securities and Exchange Commission (the ***"SEC"***) and mailed to the Company's stockholders on or about January 14, 2026, the relevant portions of which are incorporated herein by reference. A copy of the Certificate of Amendment is attached as Exhibit 3.1 hereto and incorporated herein by reference.

**Item 8.01 Other Events.**

On August 14, 2025, the Company issued a press release announcing the reverse split. A copy of the press release is filed herewith as Exhibit 99.1 and is incorporated herein by reference.

**Item 9.01 Financial Statements and Exhibits.**

## Exhibit 3.1

**Exhibit 3.1**

**<u>Certificate of Amendment</u>**

**CERTIFICATE OF AMENDMENT TO THE**

**AMENDED AND RESTATED CERTIFICATE OF INCORPORATION**

**OF**

**DECOY THERAPEUTICS INC.**

Decoy Therapeutics Inc., a corporation organized and existing under and by virtue of the General Corporation Law of the State of Delaware (the "***Corporation***"), does hereby certify as follows:

**FIRST**: The name of the Corporation is Decoy Therapeutics Inc., and the Corporation was originally incorporated pursuant to the DGCL on February 26, 2014 (as subsequently amended, the "***Certificate of Incorporation***"), under the name Flex Pharma, Inc.

**SECOND**: Article IV.A of the Certificate of Incorporation is amended and restated in its entirety to read as follows:

This Company is authorized to issue two classes of stock to be designated, respectively, "***Common Stock***" and "***Preferred Stock***." The total number of shares which the Company is authorized to issue is 110,000,000 shares. 100,000,000 shares shall be Common Stock, each having a par value of $0.0001. 10,000,000 shares shall be Preferred Stock, each having a par value of $0.0001.

Upon the filing and effectiveness (the "***Effective Time***") of this amendment to the Corporation's Amended and Restated Certificate of Incorporation, as amended, pursuant to the Delaware General Corporation Law, each 12 shares of Common Stock issued immediately prior to the Effective Time (the "***Old Common Stock***") shall be reclassified and combined into one validly issued, fully paid and non-assessable share of the Corporation's common stock, $0.0001 par value per share (the "***New Common Stock***"), without any action by the holder thereof (the "***Reverse Stock Split***") and without increasing or decreasing the authorized number of shares of Common Stock or Preferred Stock. No fractional shares of New Common Stock shall be issued as a result of the Reverse Stock Split and, in lieu thereof, upon surrender after the Effective Time of a certificate or book entry position which formerly represented shares of Old Common Stock that were issued and outstanding immediately prior to the Effective Time, any person who would otherwise be entitled to a fractional share of New Common Stock as a result of the Reverse Stock Split, following the Effective Time, shall be entitled to receive a cash payment equal to the fraction of a share of New Common Stock to which such holder would otherwise be entitled multiplied by the closing price per share of the New Common Stock on the Nasdaq Capital Market at the close of business on the date of the Effective Time. Each certificate that theretofore represented shares of Old Common Stock shall thereafter represent that number of shares of New Common Stock into which the shares of Old Common Stock represented by such certificate shall have been reclassified and combined; provided, that each person holding of record a stock certificate or certificates that represented shares of Old Common Stock shall receive, upon surrender of such certificate or certificates, a new certificate or certificates evidencing and representing the number of shares of New Common Stock to which such person is entitled under the foregoing reclassification and combination*.***

## Exhibit 99.1

![img181279516_0.gif](img181279516_0.gif)

**Decoy Therapeutics Announces 1-for-12 Reverse Stock Split**

**CAMBRIDGE, March 5, 2026 –** Decoy Therapeutics Inc. (NASDAQ: DCOY), a preclinical-stage biopharmaceutical company that is engineering the next generation of peptide conjugate therapeutics, today announced that it will effect a 1-for-12 reverse stock split at 5:00 p.m. Eastern Time, on March 6, 2026. Beginning with the opening of trading on March 9, 2026, Decoy's common stock will trade on the Nasdaq Capital Market on a split-adjusted basis under a new CUSIP number 79400X602.

The reverse stock split is intended to enable Decoy to regain compliance with the $1.00 minimum closing bid price requirement for continued listing on the Nasdaq Capital Market.

At a special meeting of stockholders held on February 24, 2026, Decoy's stockholders approved the proposal to authorize Decoy's Board of Directors to file an amendment to Decoy's amended and restated certificate of incorporation ("Certificate of Incorporation") to effect the reverse split at a ratio to be determined by the Board, ranging from 1-for-4 to 1-for-15. The specific 1-for-12 ratio was subsequently approved by Decoy's Board of Directors and the reverse stock split will be effected by filing a Certificate of Amendment to the Certificate of Incorporation with the Secretary of State of the State of Delaware.

The reverse split will affect all issued and outstanding shares of Decoy's common stock. At the effective time of the reverse stock split the number of shares of common stock issued and outstanding will be reduced from approximately 6.38 million shares to approximately 532,000 shares. All outstanding options and warrants entitling their holders to purchase shares of Decoy's common stock will be adjusted as a result of the reverse split, as required by the terms of each security. The number of shares reserved for future issuance pursuant to Decoy's 2015 Equity Incentive Plan and Employee Stock Purchase Plan will also be appropriately adjusted. The reverse stock split will affect all stockholders uniformly and will not affect any stockholder's ownership percentage of Decoy's shares (except to the extent that the reverse stock split would result in some of the stockholders receiving cash in lieu of fractional shares). Stockholders will receive cash in lieu of fractional shares based on the closing price per share of Decoy's common stock as quoted on the Nasdaq Capital Market on March 6, 2026. The reverse stock split will not reduce the number of authorized shares of common stock or preferred stock or change the par values of Decoy's common stock (which will remain at $0.0001 per share) or preferred stock (which will remain at $0.0001 per share).

Equiniti Trust Company, LLC, ("Equiniti") is acting as the exchange agent and transfer agent for the reverse stock split. Equiniti will provide instructions to stockholders with physical certificates regarding the process for exchanging their pre-split stock certificates for post-split shares in book-entry form and receiving payment for any fractional shares.

Additional information about the reverse stock split can be found in the Company's Definitive Proxy Statement filed with the Securities and Exchange Commission ("SEC") on January 9, 2026. The Proxy Statement is available at www.sec.gov or on Decoy's website at decoytx.com.
