NightHawk Biosciences Provides 2022 Year End Business Update

Durham, NC – March 31, 2023 – NightHawk Biosciences (NYSE American: NHWK), a fully-integrated biopharmaceutical company focused on developing first-in-class therapies to modulate the immune system, today provided strategic, financial, and operational updates for the year ended December 31, 2022.

Jeff Wolf, Chief Executive Officer of NightHawk, commented, “We are making progress on our transition towards biodefense and biomanufacturing through our Elusys and Scorpion subsidiaries as we wind  down our HS-110 and PTX-35 oncology programs. Pursuant to this, we are investing in our biomanufacturing technologies and capabilities, including our San Antonio and Manhattan, Kansas biologics manufacturing facilities, which we believe will position us well in the future. The manufacturing capabilities associated with these facilities are designed to streamline the development and delivery of life-saving medical countermeasures, while enabling us to offer excess capacity to third parties on a fee-for-service model.”

2022 Financial Results

● For the year ended December 31, 2022, the Company recognized revenue of $6.4 million, which included $6.0 million of product sales revenue, $0.1 million of contract revenue, and $0.3 million of CPRIT grant revenue. For the year ended December 31, 2021, the Company recognized revenue of $2.1 million for qualified expenditures under the CPRIT grant. The increase in product sales revenue was due to the sale of ANTHIM® (obiltoxaximab) to the Canadian government. The decrease in grant revenue was due to the fact that the Company recognized all $15.2 million of CPRIT grant revenue. For the year ended December 31, 2022, the Company had a grants receivable balance of $1.5 million for CPRIT proceeds not yet received, but for which the costs had been incurred or the conditions of the award had been met.

● For the year ended December 31, 2022, the Company recognized $6.4 million of cost of sales. No product sales were recognized for the year ended December 31, 2021, and thus no cost of sales was recorded. The increase was due to the cost of sales related to the ANTHIM® (obiltoxaximab) sale to the Canadian government. Cost of sales includes $5.9 million of inventory, $0.3 million of pre-acquisition backlog, and $0.2 million of shipping and fulfillment expenses.

● Selling, general and administrative (“SGA”) expenses for the years ended December 31, 2022 and 2021 were $21.1 million and $16.8 million, respectively. The increase of $4.3 million was primarily due to an increase in consulting and other professional expenses to manage the business of $3.2 million, an increase in facilities expense of $1.2 million primarily due to the opening of the Company’s San Antonio facility, an increase in personnel expense of $0.8 million due to an increase in headcount, an increase in rent expense of $0.5 million, an increase in insurance expense of $0.3 million, an increase in depreciation of $0.3 million, an increase in marketing expenses of $0.2 million, an increase in software expense of $0.2 million offset by a decrease in stock-based compensation of $2.4 million.

● Research and development expenses increased to $23.5 million from $16.5 million for the years ended December 31, 2022 and 2021, respectively. HS-110 R&D expense decreased by $1.2 million, HS-130 expense decreased by $0.2 million, and PTX-35 expense decreased by $0.3 million, all due to a decrease in site and investigator fees as a result of the closing of the clinical trials. ANTHIM® (obiltoxaximab) expenses increased due to the Company’s acquisition of Elusys in April 2022. Other program expenses decreased by $0.7 million, including preclinical costs associated with the RapidVax program, T-cell costimulatory programs, and laboratory supplies. Unallocated research expenses increased by $8.2 million primarily from license fees, sponsored research agreements for

preclinical research, as well as increased clinical and CMC consulting expenses and Skunkworx lab and personnel costs.

● Net loss attributable to NightHawk Biosciences was approximately $43.4 million, or ($1.70) per basic and diluted share, for the year ended December 31, 2022, compared to approximately $35.1 million, or ($1.41) per basic and diluted share, for the year ended December 31, 2021.

● As of December 31, 2022, the Company had approximately $44.3 million in cash, cash equivalents, and short-term investments.

Pursuant to the disclosure requirements of the NYSE American Company Guidelines Sections 401(h) and 610(b), NightHawk reports that its audited financial statements for the year ended December 31, 2022, included in the 2022 Form 10-K, contain an audit opinion from its independent registered public accounting firm that includes an explanatory paragraph related to the Company’s ability to continue as a going concern due to the fact that the Company  has suffered recurring losses from operations and has not generated significant revenue or positive cash flows from operations.

About ANTHIM

Anthrax is a life-threatening infectious disease caused by Bacillus anthracis. Cases of inhalational anthrax in humans can occur through intentional spread of B. anthracis spores as a biowarfare or bioterrorism agent. B. anthracis spores introduced through the lungs lead to inhalational anthrax, which is deadly in humans.

ANTHIM is a monoclonal antibody that binds to the protective antigen (PA) component of anthrax toxin. ANTHIM’s toxin neutralizing activity prevents entry of anthrax toxin into susceptible cells, avoiding further spread of the toxin throughout the body and the ensuing tissue damage that leads to death. ANTHIM is supplied as single-dose vials for IV infusion.

Indications and Usage

ANTHIM is indicated in adult and pediatric patients for the treatment of inhalational anthrax due to Bacillus anthracis in combination with appropriate antibacterial drugs, and for prophylaxis of inhalational anthrax when alternative therapies are not available or are not appropriate. ANTHIM should only be used for prophylaxis when its benefit for prevention of inhalational anthrax outweighs the risk of hypersensitivity and anaphylaxis. The effectiveness of ANTHIM is based solely on efficacy studies in animal models of inhalational anthrax. There have been no studies of the safety or pharmacokinetics (PK) of ANTHIM in the pediatric population. Dosing in pediatric patients was derived using a population PK approach. ANTHIM does not have direct antibacterial activity. ANTHIM should be used in combination with appropriate antibacterial drugs. ANTHIM is not expected to cross the blood-brain barrier and does not prevent or treat meningitis.

IMPORTANT SAFETY INFORMATION Including BOXED WARNING

WARNING: HYPERSENSITIVITY and ANAPHYLAXISHypersensitivity reactions, including anaphylaxis, have been reported during ANTHIM infusion. ANTHIM should be administered in monitored settings by personnel trained and equipped to manage anaphylaxis. Stop ANTHIM infusion immediately and treat appropriately if hypersensitivity or anaphylaxis occurs.

WARNINGS AND PRECAUTIONS

Hypersensitivity and anaphylaxis have been reported during the IV infusion of ANTHIM. Due to the risk of hypersensitivity and anaphylaxis, ANTHIM should be administered in monitored settings by personnel trained and equipped to manage anaphylaxis. Monitor individuals who receive ANTHIM closely for signs and symptoms of hypersensitivity reactions throughout the infusion and for a period of time after administration. Stop ANTHIM infusion immediately and treat appropriately if hypersensitivity or anaphylaxis occurs. Pre-medication with diphenhydramine is recommended prior to administration of ANTHIM. Diphenhydramine pre-medication does not prevent anaphylaxis and may mask or delay onset of symptoms of hypersensitivity.

ADVERSE REACTIONS

The safety of ANTHIM has been studied only in healthy volunteers. It has not been studied in patients with inhalational anthrax. The most frequently reported adverse reactions were headache, pruritus, infections of the upper respiratory tract, cough, vessel puncture site bruise, infusion site swelling, urticaria, nasal congestion, infusion site pain, and pain in extremity.

USE IN SPECIFIC POPULATIONS
