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.

At the 2017 Annual Meeting of Stockholders of Heat Biologics, Inc. (the “Company”) held on June 29, 2017, the stockholders of the Company approved an amendment to the Company’s Third Amended and Restated Certificate of Incorporation, as amended (the “Certificate of Incorporation”), to implement a reverse stock split of the Company’s common stock, par value $0.0002 per share, with the ratio to be determined by the Board of Directors (the “Board”) of the Company, within a range of not less than 1-for-2 or greater than 1-for-10. Subsequently on January 4, 2018, the Board determined to fix the ratio for the reverse stock split at 1-for-10. Thereafter, on January 18, 2018, 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 implement the 1-for-10 reverse split of its common stock (the “Reverse Stock Split”). The Reverse Stock Split will be effective as of 11:00 p.m. (Eastern Time) on January 19, 2018 (the “Effective Time”), and the Company’s common stock will begin trading on The NASDAQ Capital Market on a post-split basis on January 22, 2018.

As a result of the Reverse Stock Split, every ten (10) shares of the Company’s issued and outstanding common stock, par value $0.0002, prior to the Effective Time will be converted into one (1) share of common stock, par value $0.0002, reducing the number of issued and outstanding shares of the Company’s common stock from approximately 42 million to approximately 4.2 million. The Company’s transfer agent, Continental Stock Transfer & Trust Company (“Continental), will serve as exchange agent for the reverse stock split and will provide instructions to stockholders of record regarding the process for exchanging shares.

Because the Certificate of Amendment did not reduce the number of authorized shares of the Company’s common stock, the effect of the Certificate of Amendment and the Reverse Stock Split is to increase the number of shares of common stock available for issuance relative to the number of shares issued and outstanding. The Reverse Stock Split did not alter the par value of the Company’s common stock or modify any voting rights or other terms of the common stock.

No fractional shares will be issued in connection with the Reverse Stock Split. Stockholders who otherwise would be entitled to receive fractional shares because they hold a number of pre-reverse stock split shares of the Company’s common stock not evenly divisible by ten, will, in lieu of a fractional share, be entitled, upon surrender to the exchange agent of certificate(s) representing their pre-split shares or upon conversion of their shares held in book-entry, to a cash payment equal to the product obtained by multiplying (i) the closing sales price of the Company’s common stock as reported on the NASDAQ on the effective date of the Certificate of Amendment by (ii) the number of shares of common stock held by such stockholder before the Reverse Stock Split that would otherwise have been exchanged for such fractional share interest.

Continental will be issuing all of the post-split shares (except for restricted shares) through their paperless Direct Registration System (“DRS”), also known as “book-entry form,” unless otherwise requested by the stockholder. Continental will hold the shares in an account set up for the stockholder. Stockholders who wish to hold paper certificates may obtain such certificates upon request to Continental.

All book-entry or other electronic positions representing issued and outstanding shares of the Company’s common stock will be automatically adjusted. Those stockholders holding common stock in “street name” will receive instructions from their brokers.

In addition, pursuant to their terms, a proportionate adjustment will be made to the per share exercise price and number of shares issuable under all of the Company’s outstanding stock options and warrants to purchase shares of common stock, and the number of shares authorized and reserved for issuance pursuant to the Company’s equity incentive plans will be reduced proportionately.

After the Reverse Stock Split, the trading symbol for the Company’s common stock will continue to be “HTBX”. The new CUSIP number for the Company’s common stock following the Reverse Stock Split is 42237K300.

The above description of the Certificate of Amendment and the Reverse Stock Split is a summary of the material terms thereof and is qualified in its entirety by reference to the Certificate of Amendment, a copy of which is attached hereto as Exhibit 3.1, as filed with the Secretary of State of the State of Delaware on January 18, 2018.

Item 8.01.  Other Events.

As previously reported, the Company currently has until March 12, 2018 to regain compliance with the Nasdaq Stock Market’s minimum bid price requirement, and, to regain compliance, the Company’s common stock must have a minimum bid price per share of at least $1.00 for 10 consecutive business days. The principal reason for the Reverse Stock Split is to increase the per share trading price of the Company’s common stock in order to help ensure a share price high enough to satisfy the $1.00 per share minimum bid price requirement.  However, there can be no assurance that the Reverse Stock Split will have the desired effect of sufficiently raising the bid price of the Company’s common stock for the required period.

In addition, on January 19, 2018, the Company issued a press release relating to the matters described in this Current Report on Form 8-K. A copy of the press release is attached as Exhibit 99.1 to this report and is incorporated herein by reference.
