The Schall Law Firm, a national litigation firm focused on shareholder rights, is currently investigating claims on behalf of investors of Adverum Biotechnologies, Inc. (“Adverum” or “the Company”) ADVM regarding potential violations of securities laws.

This investigation centers on whether Adverum issued false or misleading statements, or failed to disclose crucial information impacting investors. On March 31, 2025, the Company filed an SEC report stating that “certain of the Company’s previously issued financial statements should no longer be relied upon due to non-cash errors identified in the accounting for tenant improvement allowances associated with an operating lease and sublease related to a building in North Carolina (the ‘NC Premises’).” Following this announcement, Adverum revealed its intention to restate financial statements for the years ended December 31, 2022, and 2023, as included in its Annual Report on Form 10-K for the year ended December 31, 2023, and for unaudited condensed consolidated quarterly financial information for periods in 2023 and 2024. As a result, shares of Adverum saw a drop of more than 12% on April 1, 2025.
