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

The disclosure set forth in Item 5.03 below is hereby incorporated herein by reference.

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

On April 14, 2026, Immunic, Inc. (the "Company") held a special meeting of stockholders (the "Special Meeting). At the Special Meeting, the Company's stockholders approved a reverse stock split of the Company's issued and outstanding common stock, par value $0.0001 per share (the "Common Stock") at a ratio in the range of 1-for-10 to 1-for-30, with such ratio (the "Reverse Stock Split") to be determined by the Board. The specific 1-for-10 ratio was subsequently determined by the Board.

On April 22, 2026, the Company filed a Certificate of Amendment (the "Certificate of Amendment") to amend the Company's certificate of incorporation, as amended and restated (the "Charter"), with the Secretary of State of the State of Delaware to effect the Reverse Stock Split at a 1-for-10 ratio (the Common Stock after giving effect to the Reverse Stock Split, the "New Common Stock").

The Company expects that the New Common Stock will begin trading on the Nasdaq Capital Market on a post-split basis under the Company's existing trading symbol, "IMUX," when the market opens on April 27, 2026. The CUSIP identifier for the New Common Stock will be 4525EP200.

As a result of the effectiveness of the Reverse Stock Split, every (10) shares Common Stock will be automatically combined, converted and changed into one (1) share of New Common Stock, without any change in the number of authorized shares or the par value per share. The Reverse Stock Split will reduce the number of shares issued and outstanding from approximately 136 million shares of Common Stock to approximately 13.6 million shares of New Common Stock. 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.

No fractional shares will be issued in connection with the Reverse Stock Split. In lieu thereof, the Company's transfer agent shall aggregate all fractional shares of Common Stock that would otherwise have been issued as a result of the Reverse Stock Split into whole shares of New Common Stock and shall arrange for the sale of such whole shares on the open market at then-prevailing prices. Stockholders of record who otherwise would be entitled to receive fractional shares because they hold a number of shares of Common Stock not evenly divisible by the reverse stock split ratio shall be entitled to receive, in lieu thereof, a cash payment equal to such holder's allocable share of the total proceeds of such sales, without interest, and such cash payment shall be made as soon as practicable following the effective time of the Reverse Stock Split.

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

**Item 8.01 Other Events.**

On April 23, 2026, the Company issued a press release to announce the effective date for the Reverse Stock Split. A copy of the press release is attached to this report as Exhibit 99.1 and is incorporated by reference herein.

1. The name of the Corporation is Immunic, Inc.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Upon the filing and effectiveness (the "***Effective Time***") of this amendment to the Corporation's Certificate of Incorporation, as amended, pursuant to the Delaware General Corporation Law, each ten (10) shares of the Common Stock issued immediately prior to the Effective Time (the "***Old Common Stock***") shall be reclassified and combined into one (1) 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***"). No fractional shares of New Common Stock shall be issued as a result of the Reverse Stock Split and, in lieu thereof, the Corporation's transfer agent shall aggregate all fractional shares of New Common Stock that would otherwise have been issued as a result of the Reverse Stock Split into whole shares of New Common Stock and shall arrange for the sale of such whole shares on the open market at then-prevailing prices. Each person who would otherwise be entitled to a fractional share of New Common Stock as a result of the Reverse Stock Split shall be entitled to receive, in lieu thereof, a cash payment equal to such holder's allocable share of the total proceeds of such sales, without interest, and such cash payment shall be made as soon as practicable following the Effective Time. Each book entry position that immediately prior to the Effective Time 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 book entry position shall have been reclassified and combined, subject to the elimination of fractional shares set forth above.

3. This Certificate of Amendment has been duly adopted by the Board of Directors and stockholders of the Corporation in accordance with Section 242 of the General Corporation Law of the State of Delaware.

4. This Certificate of Amendment shall become effective as of 12:01 AM, Eastern Time on April 27, 2026.

## Exhibit 99.1

![](image_001.jpg)

**Immunic, Inc. Announces 1-for-10 Reverse Stock Split**

**NEW YORK, April 23, 2026 –** **Immunic** **, Inc.** **(Nasdaq: IMUX)**, a late-stage biotechnology company pioneering the development of novel oral therapies for neurologic diseases (the "Company" or "Immunic"), today announced that it will effect a reverse stock split of its outstanding shares of common stock, effective as of 12:01 a.m. Eastern Time on April 27, 2026.

Immunic's common stock will continue to be traded on the Nasdaq Capital Market under the symbol "IMUX" and will begin trading on a reverse stock split-adjusted basis at the opening of the Nasdaq Capital Market on April 27, 2026. The new CUSIP number for the split-adjusted common stock will be 4525EP200.

At the Company's special meeting of stockholders on April 14, 2026, the stockholders approved a proposal to amend the Company's certificate of incorporation to effect a reverse split of the Company's outstanding common stock at a ratio in the range of 1-for-10 to 1-for-30, with such final ratio to be determined at the discretion of the Board of Directors (the "Board"). The specific 1-for-10 ratio was subsequently determined by the Board. The reverse stock split is primarily intended to allow Immunic to meet its contractual obligations under the securities purchase agreement entered into between the Company and certain institutional and accredited investors on February 12, 2026.

Immunic has filed an amendment to its certificate of incorporation, which was accepted for filing by the Department of State of Delaware on April 22, 2026. Upon the effectiveness of the reverse stock split at 12:01 a.m. on April 27, 2026, every ten shares of issued and outstanding common stock will automatically be combined and converted into one issued and outstanding share of common stock. No fractional shares will be issued in connection with the reverse stock split. In lieu thereof, the Company's transfer agent shall aggregate all fractional shares of common stock that would otherwise have been issued as a result of the reverse stock split into whole shares of common stock and shall arrange for the sale of such whole shares on the open market at then-prevailing prices. Stockholders of record who otherwise would be entitled to receive fractional shares because they hold a number of shares of common stock not evenly divisible by the reverse stock split ratio shall be entitled to receive, in lieu thereof, a cash payment equal to such holder's allocable share of the total proceeds of such sales, without interest, and such cash payment shall be made as soon as practicable following the effective time of the reverse stock split. The reverse stock split will reduce the number of issued and outstanding shares of Immunic's common stock from approximately 136 million to approximately 13.6 million.

The reverse stock split will not reduce the number of authorized shares of common stock or change the par value of the common stock. The reverse stock split will affect all stockholders uniformly and will not affect any stockholder's ownership percentage of Immunic's shares of common stock (except to the extent that the reverse stock split would result in some of the stockholders receiving cash in lieu of fractional shares). The common stock issued pursuant to the reverse stock split will remain fully paid and non-assessable. All outstanding stock options, warrants, restricted stock units, and similar securities entitling their holders to receive or purchase shares of common stock will be proportionally adjusted as a result of the reverse stock split, both in terms of their exercise prices or other stock price thresholds and as well as to the number of underlying shares, as required by the terms of each security.

Detailed information about the reverse stock split can be found in the definitive proxy statement filed with the Securities and Exchange Commission on March 2, 2026, a copy of which is available on the Company's website under the Investor Relations page.

**About Immunic, Inc.**

Immunic, Inc. (Nasdaq: IMUX) is a late-stage biotechnology company pioneering the development of novel oral therapies for neurologic diseases. The company's lead development program, vidofludimus calcium (IMU-838), is currently in phase 3 clinical trials for the treatment of relapsing multiple sclerosis, for which top-line data is expected to be available by the end of 2026. It has already shown therapeutic activity in phase 2 clinical trials in relapsing-remitting multiple sclerosis, progressive multiple sclerosis and other diseases. Vidofludimus calcium combines neuroprotective effects, through its mechanism as a first-in-class nuclear receptor-related 1 (Nurr1) activator, with additional anti-inflammatory and anti-viral effects, by selectively inhibiting the enzyme dihydroorotate dehydrogenase (DHODH). The company's development pipeline also includes earlier-stage programs, including IMU-856 and IMU-381, aimed at building a broader therapeutics platform addressing neurodegenerative, chronic inflammatory, and autoimmune-related diseases.
