NEW YORK, May 06, 2021 (GLOBE NEWSWIRE) -- SIGA Technologies, Inc. (SIGA) (NASDAQ:SIGA), a commercial-stage pharmaceutical company, today reported financial results for the three months ended March 31, 2021.

"SIGA's first quarter financial results reflect a positive general trend with international sales," said Phil Gomez, CEO of SIGA. "In 2020, we had $2 million total of international sales, while in this first quarter alone, we've delivered approximately $3 million of oral TPOXX® to the Public Health Agency of Canada ("PHAC"), and in April we delivered an additional $7 million of oral TPOXX® to PHAC. With respect to deliveries of oral TPOXX® to the Biomedical Advanced Research and Development Authority ("BARDA"), we continue to expect those sales pursuant to our 2018 Contract to be concentrated in the second half of 2021, in contrast to international sales which we expect to be concentrated in the first half of 2021."

Summary Financial Results

($ in millions, except per share amounts)

Three Months Ended March 31, 2021 in comparison to Three Months Ended March 31, 2020

Recent Key Activities:

In April and March 2021, the Company delivered approximately $7 million and $3 million, respectively, of oral TPOXX® to PHAC under the contract that was awarded in January 2021 ("2021 PHAC Contract"). The April delivery will be reflected in the second quarter financial results. The 2021 PHAC Contract, as well as the contract for the procurement of oral TPOXX® with the Canadian Military, were coordinated between SIGA and Meridian Medical Technologies, Inc. under the international promotion agreement (as amended) that was entered into by the parties in June 2019.
In April 2021, the Company filed a new drug application ("NDA") with the U.S. Food and Drug Administration ("FDA") for the intravenous formulation of TPOXX ("IV TPOXX®"). The approval of a second formulation of TPOXX® would increase the addressable patient population to those who are too ill to swallow oral capsules. The FDA review process will typically take 10 months for this type of submission.
In March 2021, the Company announced a strategic partnership with Cipla Therapeutics to deliver sustained innovation and access to novel antibacterial drugs. The purpose of the strategic partnership is to provide BARDA, a department within the U.S. Department of Health and Human Services ("HHS"), with potential solutions for biothreat and public health needs in connection with anti-microbial resistance.

Share Repurchase Activity

During the first quarter of 2021, SIGA repurchased approximately 1 million shares of its common stock, for approximately $6.5 million. Since the inception of the current share repurchase program in March 2020, the Company has cumulatively repurchased approximately 5.6 million shares of its common stock for approximately $35 million.

COVID-19 Pandemic

The COVID-19 pandemic has caused significant societal and economic disruption. Such disruption, and the associated risks and costs, are expected to continue for an indeterminate period of time. Given the uncertain scale, scope, and current and future impact of the pandemic, the Company is regularly reviewing business and financial risks, and seeking coordination with its government partners with respect to the performance of current and future contract timing and execution. Additionally, the Company is coordinating closely with service providers and vendors, in particular contract manufacturing organizations that constitute our supply chain, with respect to actions and risks caused by the COVID-19 pandemic. Finally, the Company has proactively provided its employees with resources and other support to help ensure continued success in remote work settings as they navigate the current pandemic environment.

The COVID-19 pandemic has not adversely affected the liquidity position of the Company, nor is it currently expected to have a material adverse effect on the financial condition of the Company. The pandemic could delay the timing of international contract awards for oral TPOXX® given the need of government officials to focus on meeting the demands of the current COVID-19 pandemic. Otherwise, the pandemic is not currently expected to have a material adverse effect on the short-term financial results of the Company, although the Company cannot provide assurances as to the ultimate impact of the pandemic upon the broader macro environment or the Company's industry.

About Smallpox¹

Smallpox is a contagious, disfiguring and often deadly disease that has affected humans for thousands of years. Naturally occurring smallpox was eradicated worldwide by 1980, the result of an unprecedented global immunization campaign. Samples of smallpox virus have been kept for research purposes. This has led to concerns that smallpox could someday be used as a biological warfare agent. A vaccine can prevent smallpox, but the risk of the current vaccine's side effects is too high to justify routine vaccination for people at low risk of exposure to the smallpox virus.
