Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On May 20, 2015, SIGA Technologies, Inc. (the “Company”) received notice from the Hearings Advisor for The Nasdaq Stock Market LLC (“Nasdaq”) stating that Nasdaq has determined that the Company’s securities will be delisted from Nasdaq. On May 21, 2015, Nasdaq filed a Form 25-NSE with the Securities and Exchange Commission to remove the Company’s securities from listing and registration on Nasdaq. The Form 25-NSE stated that Nasdaq had determined that the Company no longer qualified for listing on Nasdaq pursuant to Nasdaq Listing Rule 5110(b).

As previously disclosed, the Company’s common stock was suspended from trading on the Nasdaq Global Market on March 20, 2015 and has traded on the OTC Markets under the “SIGAQ” symbol since that time.

The delisting is a consequence of the Company’s September 16, 2014 filing for relief under Chapter 11 of the United States Bankruptcy Code. The Company’s Chapter 11 filing was precipitated by its ongoing litigation with PharmAthene, Inc.
