current expectations include, among others, the Company’s ability to obtain regulatory approvals for commercialization of its product candidates,

including its COVID-19 vaccines and IBIO-101, or to comply with ongoing regulatory requirements, regulatory limitations relating to its ability to promote or

commercialize its product candidates for specific indications, acceptance of its product candidates in the marketplace and the successful development,

marketing or sale of products, its ability to maintain its license agreements, the continued maintenance and growth of its patent estate, its ability to establish

and maintain collaborations, its ability to obtain or maintain the capital or grants necessary to fund its research and development activities, competition, its

ability to retain its key employees or maintain its NYSE American listing, and the other factors discussed in the Company’s most recent Annual Report on

Form 10-K and the Company’s subsequent filings with the SEC, including subsequent periodic reports on Forms 10-Q and 8-K. The information in this

• Can promote or retard tumorigenesis in a contextdependent

manner

• Recent studies have revealed their roles in immune

• Response to chemotherapy is highly variable3

• CSF is a priority agricultural biothreat

• CSF poses a risk to $7.0B US swine exports

• Current emergency use CSF vaccines have
