Item
3.03 Material Modification to Rights of Security Holders.
To
the extent required by Item 3.03 of Form 8-K, the information regarding the Reverse Stock Split (as defined below) contained in Item
5.03 of this Current Report on Form 8-K is incorporated by reference herein.
Item
5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.
On
March 3, 2026, Tevogen Bio Holdings Inc. (the “Company”) filed a Certificate of Amendment to its Certificate of Incorporation
(the “Certificate of Amendment”) with the Secretary of State of the State of Delaware to effect a 1-for-50 reverse stock
split of the issued and outstanding common stock, par value $0.0001 per share (the “Common Stock”), of the Company (the “Reverse
Stock Split”), to be effective as of March 6, 2026 (the “Effective Date”). The Common Stock will be quoted on the Nasdaq
Stock Market on a post-split basis at the open of business on the Effective Date.
As
disclosed in the Company’s Current Report on Form 8-K filed on February 25, 2026, the Company’s stockholders approved the
Certificate of Amendment at a special meeting of stockholders held on February 19, 2026, at a ratio between 1-for-25 and 1-for-85, with
the final ratio, implementation and timing to be determined by the Board of Directors of the Company (the “Board”) in its
sole discretion.
Effects
of the Reverse Stock Split
As
of March 3, 2026, there were 202,416,556 shares of the Company’s Common Stock issued and outstanding. The Reverse Stock Split reduces
the total number of issued and outstanding shares of Common Stock by a ratio of 1-for-50. Accordingly, each of our stockholders will
own fewer shares of Common Stock as a result of the Reverse Stock Split. However, the Reverse Stock Split affects all stockholders uniformly
and does not affect any stockholder’s percentage ownership interest in the Company, except to the extent that the Reverse Stock
Split would result in an adjustment to a stockholder’s ownership of Common Stock due to the treatment of fractional shares in the
Reverse Stock Split as described below.
The
Company is currently authorized to issue a maximum of 800,000,000 shares of our Common Stock. The number of authorized shares of Common
Stock will not change as a result of the Reverse Stock Split.
CUSIP
Number; Symbol
In
connection with the Reverse Stock Split, the CUSIP number for the Common Stock will change to 88165K200. The trading symbol for the Common
Stock, TVGN, will remain unchanged.
Split
Adjustment; Treatment of Fractional Shares
On
the Effective Date, the total number of shares of Common Stock held by each stockholder of the Company will be converted automatically
into the number of shares of Common Stock equal to: (i) the number of issued and outstanding shares of Common Stock held by each such
stockholder immediately prior to the Reverse Stock Split divided by (ii) 50.
The
Company does not intend to issue fractional shares in the event that a stockholder owns a number of shares of Common Stock that is not
evenly divisible by the Reverse Stock Split ratio. Instead, any fractional share that would otherwise result from the Reverse Stock Split
because the stockholder owns a number of shares not evenly divisible by the ratio will instead settle in cash. The cash amount to be
paid to each holder of shares of Common Stock will be equal to the resulting fractional interest in one share of our Common Stock to
which the stockholder would otherwise be entitled, multiplied by the closing trading price of our Common Stock on the trading day immediately
preceding the Effective Date (as adjusted to give effect to the Reverse Stock Split), without interest.
Also
on the Effective Date, all convertible preferred stock and warrants of the Company outstanding immediately prior to the Reverse Stock
Split will be adjusted by dividing the number of shares of Common Stock into which such securities are convertible or exercisable by
50 and multiplying the per share conversion or exercise price thereof by 50, all in accordance with the terms of the plans, agreements,
or arrangements governing such securities.
Stockholders
who hold shares of Common Stock electronically in “book-entry” form will have their holdings electronically adjusted by Continental
Stock Transfer and Trust Company, the transfer agent for the Common Stock (and, for beneficial owners, by their brokers or banks that
hold in “street name” for their benefit, as the case may be), to give effect to the Reverse Stock Split. If any book-entry
statement representing pre-Reverse Stock Split shares of Common Stock to be exchanged contain a restrictive legend or notation, as applicable,
the book-entry statement representing post-Reverse Stock Split shares of Common Stock will contain the same restrictive legend or notation.
The
foregoing summary of the Certificate of Amendment is qualified in its entirety by reference to the Certificate of Amendment, a copy of
which is filed as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated by reference herein.

CERTIFICATE
OF AMENDMENT TO THE
CERTIFICATE
OF INCORPORATION OF
TEVOGEN
BIO HOLDINGS INC.
Tevogen
Bio Holdings Inc. (the “Corporation”), a corporation duly organized and existing under the General Corporation Law
of the State of Delaware (the “DGCL”), hereby certifies as follows:
| FIRST: |
That
the Board of Directors of the Corporation has duly adopted resolutions authorizing the Corporation to execute and file with the Secretary
of State of the State of Delaware this Certificate of Amendment to the Certificate of Incorporation (this “Amendment”)
to combine each fifty (50) outstanding shares of the Corporation’s common stock, par value $0.0001 per share (the “Common
Stock”), into one (1) validly issued, fully paid and non-assessable share of Common Stock. |
| |
|
| SECOND: |
That
this Amendment was duly adopted in accordance with the terms of the Corporation’s Certificate of Incorporation and the provisions
of the DGCL by the Board of Directors and stockholders of the Corporation. |
| |
|
| THIRD: |
That
upon the effectiveness of this Amendment, the Corporation’s Certificate of Incorporation is hereby amended such that Section
4.01 of ARTICLE IV is amended and restated in its entirety to read as set forth below, with no changes to be made to the subsequent
sections of ARTICLE IV: |
Section
4.01 Authorized Classes of Stock. The total number of shares of stock of all classes of capital stock that the Corporation is authorized
to issue is eight hundred twenty million (820,000,000), of which eight hundred million (800,000,000) shares shall be shares of common
stock having a par value of $0.0001 per share (“Common Stock”) and twenty million (20,000,000) shares shall be shares
of preferred stock having a par value of $0.0001 per share (“Preferred Stock”). Except as provided in any certificate
of designations of any series of Preferred Stock, the number of authorized shares of Preferred Stock and Common Stock may be increased
or decreased (but not below the number of shares thereof then outstanding) from time to time by the affirmative vote of the holders representing
at least a majority of the voting power of the outstanding shares of capital stock of the Corporation entitled to vote thereon, voting
together as a single class, irrespective of the provisions of Section 242(b)(2) of the DGCL (or any successor provision thereto),
and no vote of the holders of any of the Common Stock or Preferred Stock voting separately as a class or series shall be required therefor.
Upon the effectiveness of this Certificate of Amendment to the Certificate of Incorporation of the Corporation, each fifty (50) shares
of the Corporation’s Common Stock issued and outstanding at such time shall, automatically and without any further action on the
part of the Corporation or the holder thereof, be combined into one (1) validly issued, fully paid and non-assessable share of Common
Stock (the “Reverse Stock Split”). The par value of the Common Stock following the Reverse Stock Split shall remain
$0.0001 per share. No fractional shares shall be issued, and, in lieu thereof, the Corporation shall pay cash equal to such fraction
multiplied by the fair market value of a share of Common Stock, as determined by the Board of Directors.
| FOURTH: |
This
Amendment shall be effective as of March 6, 2026, at 12:01 a.m. Eastern Time (the “Effective Time”). |
IN
WITNESS WHEREOF, the Corporation has caused this Certificate of Amendment to the Certificate of Incorporation to be executed by Kirti
Desai, its Chief Financial Officer, this 3rd day of March, 2026.

Tevogen
Announces Reverse Stock Split
March
4, 2026
WARREN,
N.J., Tevogen (“Tevogen Bio Holdings Inc.” or “Company”) (Nasdaq: TVGN) today announced
that its Board of Directors (the “Board”) has approved a reverse stock split of its common stock at a ratio of 50 for 1.
Stockholders previously approved the reverse stock split on February 19, 2026, and provided the Board with discretion to determine the
final reverse stock split ratio.
The
reverse stock split is being conducted to regain compliance with the $1.00 minimum bid price requirement for continued listing on the
Nasdaq Global Market (“Nasdaq”) and is expected to become effective at 12:01 a.m. on March 6, 2026 (the “Effective
Date”). The Company’s common stock is expected to begin trading on Nasdaq on a split-adjusted basis as of the beginning of
trading on March 6, 2026, under the same symbol, “TVGN”, and a new CUSIP number, 88165K 200.
On
the Effective Date, every 50 shares of the Company’s common stock issued and outstanding will be automatically converted into one
share. No fractional shares will be issued in connection with the reverse stock split. Holders of common stock who would otherwise receive
a fractional share pursuant to the reverse stock split will receive cash in lieu of the fractional share. The shares of common stock
underlying the Company’s outstanding equity awards and warrants, the number of shares available for issuance under the Company’s
equity incentive plan, and the number of shares issuable upon conversion of the Company’s outstanding preferred stock will also
be adjusted accordingly.
The
reverse stock split will be applicable to all holders of our common stock uniformly and will not affect any stockholder’s percentage
of ownership interest in the Company, except for any changes resulting from the treatment of fractional shares. This includes percentage
of ownership for Tevogen directors and executive officers who currently beneficially own more than 70% of the Company’s common
stock. Further, the reverse stock split will not affect the Company’s underlying business operations or total stockholders’
equity.
The
following chart shows percentage ownership of the Company’s common stock based on 201,417,282 shares issued and outstanding as
of January 14, 2026.

Additional
information regarding the reverse stock split is available in the Company’s definitive proxy statement filed with the U.S. Securities
and Exchange Commission on January 26, 2026.
