SIGA Announces Commencement of Rights Offering

NEW YORK--()--SIGA Technologies, Inc. (“SIGA” or the “Company”) (OTCMKTS:SIGA) today announced that it has commenced a rights offering (the “Rights Offering”) for approximate gross proceeds of $35,000,000. As part of the Rights Offering, each stockholder of the Company is receiving one subscription right for each share of common stock owned as of the previously announced record date of October 12, 2016. Each subscription right will entitle its holder to invest $0.65 towards the purchase of shares of the Company’s common stock at a subscription price equal to the lower of $1.50 or 85% of the volume weighted average price of our shares during market hours on the expiration date of the Rights Offering, as more fully described in the prospectus relating to the Rights Offering.

The Rights Offering is expected to expire at 5:00 pm, New York City time, on November 8, 2016, subject to early termination or extension. Subscription rights that are not exercised prior to the expiration date will expire and have no value.

Through the Rights Offering, the company will issue subscription rights necessary to raise an aggregate of $35,284,792. The Company has entered into an investment agreement, or ‘‘backstop agreement,’’ pursuant to which certain parties have agreed to backstop the Rights Offering by purchasing from the Company, at the subscription price pursuant to a separate private placement, any unsubscribed shares of common stock in the Rights Offering to reach the aggregate amount.

Proceeds from the Rights Offering, in combination with other sources of liquidity, will be used by the Company to satisfy the remaining portion of PharmAthene Inc.’s judgment against the Company.

Stockholders who hold their shares directly will receive a prospectus, together with a letter from the Company describing the Rights Offering, subscription rights certificate and related documentation. Those wishing to exercise their rights should review all materials, properly complete and execute the subscription rights certificate and deliver it and payment in full to the subscription agent:

Attn: Corporate Actions
Tel: (718) 921.8200
