Heat Biologics Provides Third Quarter 2021 Business Update

Durham, NC – November 10, 2021 – Heat Biologics, Inc. (“Heat”) (NASDAQ: HTBX), today provided strategic, financial, and operational updates for the third quarter ended September 30, 2021.

Jeff Wolf, Chief Executive Officer of Heat, commented, “Our clinical and preclinical programs are progressing well. In September, we expanded dosing in our Phase 1 clinical trial of monoclonal antibody PTX-35 in patients with solid tumors, and are planning a clinical development pathway to utilize PTX-35 in the context of inflammatory disease. We are also preparing for an end of Phase 2 meeting with the FDA for HS-110 to discuss potential Phase 3 registration pathways.”

“Additionally, we recently announced our new biosecurity/biodefense initiative, which leverages our gp96 platform against known or unknown future biological threats. In the short time since launching this program, we have filed patents to protect our proprietary technology and have established collaborations with leading institutions to advance our research. At the same time, we’ve assembled a knowledgeable and experienced biothreat advisory board that is well-versed on our biothreat platform. We plan to provide further updates on our biodefense efforts in the near future.”

“Our strategic vision is to become a fully integrated, immune system-focused biopharmaceutical company, and we continue to evolve in that direction. In August we announced the groundbreaking of our new wholly-owned Scorpion biomanufacturing and bioanalytic subsidiary, which is designed to support our internal manufacturing needs as we advance our programs as well as to offer much-needed biomanufacturing/bioanalytic services to other biotech and pharmaceutical clients. Our ultimate goal is to reduce development costs, accelerate development timelines, and ensure the highest levels of quality by controlling the entire process internally. Overall, we have maintained a solid balance sheet and are well positioned to execute on a number of key milestones that we believe will drive significant value for shareholders.”

Third Quarter 2021 Financial Results

●

Recognized $0.5 million of grant revenue for qualified expenditures under the CPRIT grant for the quarter ended September 30, 2021 compared to $0.8 million for the quarter ended September 30, 2020. The decrease in grant revenue in the current-year period primarily reflects the expected timing of completion of deliveries under the current phase of the contracts. As of September 30, 2021, we had a grant receivable balance of $0.9 million for CPRIT proceeds not yet received but for which the costs had been incurred or the conditions of the award had been met. We continue our efforts to secure future non-dilutive grant funding to subsidize ongoing research and development costs.

●

Research and development expense was $4.4 million and $3.2 million for the three months ended September 30, 2021 and 2020, respectively.

●

General and administrative expense was $3.4 million and $6.6 million for the three months ended September 30, 2021 and 2020. The decrease was primarily due to a decrease in stock-based compensation expense of $3.9 million.

●

Net loss attributable to Heat Biologics was approximately $7.4 million, or ($0.30) per basic and diluted share for the quarter ended September 30, 2021 compared to a net loss of approximately of $8.9 million, or ($0.43) per basic and diluted share for the quarter ended September 30, 2020.
