Item 8.01 Other Events.
On June 16, 2026, Altimmune,
Inc. (the “Company”) announced plans to relocate its corporate headquarters from Gaithersburg, Maryland to Morristown, New
Jersey later this year. The new headquarters is in a geography with a strong presence of biopharmaceutical companies, which is expected
to support the Company’s ability to attract top-tier talent in its hybrid business model, as the Company continues its growth as
a late-stage development company.
The Company has entered into an office lease agreement for the New
Jersey headquarters where the Company will make rent payments of approximately $300,000 annually for the 5-year lease term. The
move of the headquarters is expected to help the company achieve cost efficiencies over the long term.
Cautionary Note Regarding Forward Looking Statements
This Current Report on Form 8-K and certain of the materials
filed herewith contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, as
amended, including, without limitation, statements regarding the Offering and anticipated closing, and expectations regarding our
cash runway, use of capital, expenses and other future financial results. The words “may,” “might,”
“will,” “could,” “would,” “should,” “expect,” “plan,”
“anticipate,” “intend,” “believe,” “expect,” “estimate,”
“seek,” “predict,” “future,” “project,” “potential,”
“continue,” “target” and similar words or expressions are intended to identify forward-looking statements,
although not all forward-looking statements contain these identifying words. Any forward-looking statements, such as those related
to the anticipated plan to relocate the Company’s headquarters, the anticipated timing of the relocation, the potential of the
new location to assist in attracting talent, the continued growth of the company and any potential cost efficiencies created by the
move, are subject to a number of risks, uncertainties and important factors that may cause actual events or results to differ
materially from those expressed or implied by any forward-looking statements contained in this Current Report on Form 8-K. These
statements are based on management's current expectations and are not predictions of actual performance. These forward-looking
statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on, by any investor

difficult or impossible to predict and will differ from assumptions. These and other risks and uncertainties are described in
greater detail in the section entitled “Risk Factors” in the Company’s Annual Report on Form 10-K for the year
