Why they said they were late

Adverum Biotechnologies, Inc. (the “Company”) is unable to timely file with the Securities and Exchange Commission (“SEC”) its Annual Report on Form 10-K for the year ended December 31, 2024 (the “2024 Annual Report”) without unreasonable effort or expense. As previously disclosed, on March 28, 2025, the Audit Committee of the Board of Directors (the “Audit Committee”) of the Company, following consultation with the Company’s management and independent registered public accounting firm, Ernst & Young LLP, concluded 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 an operating lease and sublease related to a building in North Carolina (the “NC Premises”). In January 2021, the Company entered into the operating lease for the NC Premises, and in October 2021, the Company entered into the sublease agreement with Jaguar Gene Therapy, LLC, who subsequently assigned the sublease to Advanced Medical Partners, LLC as the subtenant for the NC Premises, through the remainder of the lease term. While preparing the consolidated financial statements as of and for the year ended December 31, 2024, management discovered non-cash errors in the Company’s accounting for its operating lease and sublease of the NC Premises. The errors relate solely to the Company’s accounting for tenant improvement allowances provided by the landlord to the Company under its operating lease, which were subsequently conveyed from the Company to the subtenant under the sublease. The errors affect the reported amounts of non-cash assets and liabilities, and non-cash general and administrative expenses, related to the lease and sublease (the “Misstatements”)

About this score

reportingrisk.com scores every active US filer on three things a company tells the SEC about itself: late-filing notices on Form NT, 8-K item 4.02 (past accounts declared unreliable) and 4.01 (auditor changes). 1,012 are flagged today.

Every score is frozen and checked twelve months later. Across 91,452 of them, a company scoring 4 or more ended that year delisted, bankrupt, restated or silent 17.2% of the time, against 4.0% for a clean record. Scores before 2026-09-27 were reconstructed from the filing history as it stood at each date, so the record is a backtest rather than years of live calls.

Every item above is a filing this company made with the SEC.
