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

Effective May 3, 2022, Heat Biologics, Inc., a Delaware corporation (the “Company”), changed its name to NightHawk Biosciences, Inc. (the “Name Change”) by filing a Certificate of Amendment (the “Certificate of Amendment”) to its Third Amended and Restated Certificate of Incorporation (the “Third Amended and Restated Certificate”) with the Secretary of State of the State of Delaware. In accordance with the General Corporation Law of the State of Delaware (the “DGCL”), the board of directors of the Company (the “Board”) approved the Name Change and the Certificate of Amendment. Pursuant to Section 242(b)(1) of the DGCL, stockholder approval was not required for the Name Change or the Certificate of Amendment.

In addition, effective May 3, 2022, the Company amended and restated its Amended and Restated Bylaws (the “Bylaws”) to reflect the Name Change (the “Second Amended and Restated Bylaws”). The Second Amended and Restated Bylaws contain no other changes. In accordance with the DGCL and the Bylaws, the Board approved the Second Amended and Restated Bylaws, and stockholder approval was not required for such amendment.

The foregoing descriptions are only a summary of the Certificate of Amendment and the Second Amended and Restated Bylaws, and are qualified in their entirety by reference to the full text of the Certificate of Amendment and the Second Amended and Restated Bylaws, copies of which are filed as Exhibits 3.1 and 3.2, respectively, to this Current Report on Form 8-K and incorporated by reference herein.

Item 7.01.   Regulation FD Disclosure.

On May 3, 2022, the Company issued a press release announcing the Name Change and the Symbol Change (as defined below). A copy of the press release is included as Exhibit 99.1 to this Current Report on Form 8-K and incorporated by reference herein.

The information in Item 7.01 of this Current Report on Form 8-K, including Exhibit 99.1, is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed to be incorporated by reference in any registration statement or other document filed under the Securities Act of 1933, as amended, or the Exchange Act.

Item 8.01.   Other Events.

In connection with the Name Change, the Company’s common stock, par value $0.0002 per share (the “Common Stock”), will begin trading on the NYSE American LLC under the new ticker symbol “NHWK,” effective as of the opening of trading hours on May 3, 2022 (the “Symbol Change”). The CUSIP number of the Common Stock will remain the same.

The Name Change and Symbol Change do not affect the rights of the Company’s security holders. The Common Stock will continue to be traded on the NYSE American LLC. Following the Name Change, the stock certificates of the Common Stock, which reflect the former name of the Company, will continue to be valid. Certificates reflecting the Name Change will be issued in due course as old stock certificates are tendered for exchange or transfer to the Company’s transfer agent.
