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

On February 8, 2019, Celldex Therapeutics, Inc. (the “Company”) filed a Certificate of Amendment to the Company’s Third Restated Certificate of Incorporation with the Secretary of State of the State of Delaware (the “Certificate of Amendment”), which effected, immediately upon filing, a one-for-fifteen reverse stock split (the “Reverse Stock Split”) of the Company’s issued and outstanding common stock, $0.001 par value per share (the “Common Stock”).

As a result of the Reverse Stock Split, every fifteen shares of Common Stock issued and outstanding was converted into one share of Common Stock and the total number of shares of Common Stock outstanding will be reduced from approximately 181.8 million shares to approximately 12.1 million shares. No fractional shares were 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 proportional cash payment.

The Reverse Stock Split did not change the par value of the Common Stock or the authorized number of shares of Common Stock. All outstanding stock options entitling their holders to purchase shares of Common Stock were adjusted as a result of the Reverse Stock Split, as required by the terms of these securities.

As previously disclosed, at the Company’s 2018 Annual Meeting of Stockholders held on June 13, 2018 (the “Annual Meeting”) the stockholders of the Company approved a proposal to amend the Company’s Third Restated Certificate of Incorporation to effect a reverse stock split of the Common Stock at a ratio in the range of one-for-ten to one-for-fifteen at the discretion of the Board of Directors of the Company (the “Board”). Pursuant to the authority granted by the Company’s stockholders at the Annual Meeting, the Board approved the Reverse Stock Split.

Trading of the Common Stock on a Reverse Stock Split-adjusted basis on the Nasdaq Capital Market will begin at the opening of trading on February 11, 2019. In connection with the Reverse Stock Split, the Common Stock will also commence trading with a new CUSIP number, 15117B202, at such time.

Computershare Trust Company, N.A., the Company’s transfer agent, is acting as the exchange agent for the Reverse Stock Split and will provide instructions to stockholders of record regarding the process for exchanging shares. Those stockholders holding Common Stock in “street name” will receive instructions from their brokers.

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

On February 8, 2019, the Company issued a press release with respect to the Reverse Stock Split, a copy of which is being furnished as Exhibit 99.1 to this Form 8-K.

Exhibit 3.1

CERTIFICATE OF AMENDMENT OF

CERTIFICATE OF INCORPORATION

OF

CELLDEX THERAPEUTICS, INC.

(Pursuant to Section 242 of the Delaware General Corporation Law)

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

FIRST: That at a meeting of the Board of Directors of the Corporation on April 15, 2018 resolutions were duly adopted setting forth a proposed amendment to the Third Restated Certificate of Incorporation, as amended, of the Corporation, declaring such amendment to be advisable and calling a meeting of stockholders of the Corporation for consideration thereof.  The resolution setting forth the proposed amendment is as follows:

RESOLVED, that the Certificate of Amendment of the Corporation be amended to effect a reverse stock split of the Corporation’s common stock by adding the following paragraph to Article IV:

“Effective upon the effective time of this Certificate of Amendment of the Certificate of Incorporation with the Secretary of State of the State of Delaware (the “Split Effective Time”), the shares of Common Stock issued and outstanding immediately prior to the Split Effective Time and the shares of Common Stock issued and held in the treasury of the Corporation immediately prior to the Split Effective Time are reclassified into a smaller number of shares such that each ten to fifteen shares of issued Common Stock immediately prior to the Split Effective Time is reclassified into one share of Common Stock, the exact ratio within the ten to fifteen range to be determined by the Board of Directors of the Corporation prior to the Split Effective Time and publicly announced by the Corporation. Notwithstanding the foregoing, no fractional shares of Common Stock shall be issued as a result of the reclassification. In lieu of any fractional share to which the holder would otherwise be entitled, the Corporation shall pay the holder cash equal to the product of such fraction multiplied by the Common Stock’s fair market value as determined in good faith by the Board of Directors as of the Split Effective Time. Each stock certificate that, immediately prior to the Split Effective Time, represented shares of Common Stock that were issued and outstanding immediately prior to the Split Effective Time shall, from and after the Split Effective Time, automatically and without the necessity of presenting the same for exchange, represent that number of whole shares of Common Stock after the Split Effective Time into which the shares of Common Stock formerly represented by such certificate shall have been reclassified, provided, however, that each person of record holding a certificate that represented shares of Common Stock that were issued and outstanding immediately prior to the Split Effective Time shall receive, upon surrender of such certificate, a new certificate evidencing and representing the number of whole shares of Common

Stock after the Split Effective Time into which the shares of Common Stock formerly represented by such certificate shall have been reclassified.”

SECOND: The amendment of the Third Restated Certificate of Incorporation set forth herein has been duly adopted by resolution of the Corporation’s Board of Directors and was considered and duly authorized by the stockholders of the Corporation at the Annual Meeting of Stockholders duly called and held upon notice in accordance with Section 222 of the General Corporation Law of the State of Delaware at which meeting the requisite number of shares as required by statute were voted in favor of the amendment.

THIRD:  That said amendment was duly adopted in accordance with the applicable provisions of Section 242 of the General Corporation Law of the State of Delaware.

2

IN WITNESS WHEREOF, the undersigned has executed this Certificate of Amendment this 8th day of February, 2019.

Exhibit 99.1

Celldex Therapeutics Announces Reverse Stock Split

HAMPTON, N.J., February 8, 2019, — Celldex Therapeutics, Inc. (NASDAQ:CLDX) (“Celldex” or the “Company”) today announced that its Board of Directors has approved a one-for-fifteen reverse stock split of its common stock that became effective today upon the filing with the Secretary of the State of Delaware a Certificate of Amendment to its Certificate of Incorporation. Beginning on February 11, 2019, Celldex’s common stock will trade on the Nasdaq Capital Market on a split-adjusted basis under the new CUSIP number 15117B202.

As previously disclosed, at the Company’s Annual Meeting of Stockholders held on June 13, 2018, Celldex stockholders approved a proposal authorizing the Company’s Board of Directors to effect a reverse stock split by a ratio of not less than one-for-ten and not more than one-for-fifteen.

The reverse stock split uniformly affects all issued and outstanding shares of the Company’s common stock. The reverse stock split will not alter any stockholder’s percentage ownership interest in Celldex, except to the extent that the reverse stock split results in fractional shares. No fractional shares will be issued in connection with the reverse stock split. Stockholders who would otherwise be entitled to receive a fractional share will instead receive a cash payment based on the closing sales price of the Company’s common stock on February 7, 2019. The par value of the Company’s common stock will remain unchanged at $0.001 per share after the reverse stock split.

The reverse stock split proportionately affects the number of shares of common stock available for issuance under the Company’s equity incentive plans and proportionately reduces the number of shares of common stock issuable upon the exercise of stock options immediately prior to the reverse split.

The reverse stock split will reduce the number of shares of common stock issued and outstanding from approximately 181.8 million to approximately 12.1 million. There is no change to the number of authorized shares.

Computershare Trust Company, N.A. is acting as the exchange agent and transfer agent for the reverse stock split. Computershare will provide instructions to stockholders with physical certificates regarding the optional process for exchanging their pre-split stock certificates for post-split stock certificates and receiving payment for any fractional shares.
