Dear Sir or Madam:

Pursuant to Rule 477 promulgated under the Securities Act of 1933, as amended (the “Securities Act”), Scorpius Holdings, Inc. f/k/a Nighthawk Biosciences, Inc. (the “Registrant”) hereby requests that the United States Securities and Exchange Commission (the “Commission”) consent to the withdrawal of the Registrant’s Registration Statement on Form S-3, File No. 333-276144, together with all amendments and exhibits thereto (the “Registration Statement”). The Registrant does not intend to conduct the offering of the shares of common stock contemplated by the Registration Statement due to changed circumstances since the filing of the Registration Statement. No shares of common stock of the Registrant have been or will be issued or sold under the Registration Statement.

Accordingly, the Registrant requests an order granting the withdrawal of the Registration Statement to be issued by the Commission as soon as possible.

The Registrant acknowledges that no refund will be made for fees paid to the Commission in connection with filing of the Registration Statement. However, the Registrant requests, in accordance with Rule 457(p) under the Securities Act that all fees paid to the Commission in connection with the filing of the Registration Statement be credited to the Registrant’s account to be offset against the filing fee for any future registration statement or registration statements.

Please contact Leslie Marlow at (212) 885-5358 or Melissa Palat Murawsky at (215) 569-5732 with any questions you may have concerning this application of withdrawal of the Registration Statement, and please notify either Ms. Marlow or Ms. Murawsky when this application of withdrawal has been granted.
