ALTIMMUNE, INC.

ALTIMMUNE, INC. is a Corporation in WILMINGTON, United States with 1 ISIN-identified security mapped to its LEI, which is how regulators tie a traded instrument to the issuer behind it.

The LEI has been on record for 8 years, since 5 Sep 2018. That puts it right on the median for United States, where half of all LEIs date from before 2019.

The next annual re-validation is due 26 Sep 2027, 323 days from now.

This archive holds 2 versions of the record. The most recent change was on 3 Sep 2026 and altered the next renewal; the oldest version we hold dates from 6 Jul 2026. GLEIF publishes only the current state, so superseded values are not available from the source.

The LEI is issued and maintained by Herausgebergemeinschaft Wertpapier-Mitteilungen Keppler, Lehmann GmbH & Co. KG, one of the Local Operating Units accredited by GLEIF.

Beyond the LEI, 1 ISIN is mapped to this entity in the GLEIF cross-reference files.

No direct accounting-consolidating parent is reported, because no parent prepares consolidated accounts that include it. GLEIF requires this to be stated explicitly rather than left blank, so the absence is itself a data point.

No ultimate accounting-consolidating parent is reported, because no parent prepares consolidated accounts that include it. GLEIF requires this to be stated explicitly rather than left blank, so the absence is itself a data point.

The LEI registration is issued, and the entity status (active) records whether the legal entity itself still exists. The two are independent: an LEI can lapse while the company trades on, and it can stay issued after the company has been dissolved.
