Why they said they were late

Adaptimmune Therapeutics plc (the “Registrant” or the “Company”) is filing this Notification of Late Filing on Form 12b-25 with respect to its Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (the “Form 10-K”) because the Company needs additional time to prepare and review certain information and complete its review of its financial statements and other disclosures in the Form 10-K which could not be completed by March 1, 2022 without incurring unreasonable effort and expense. The delay is due to turnover and unanticipated absences in the finance department affecting the general review process and has not permitted the Company’s independent registered public accounting firm to complete their audit and report on the financial statements by March 1, 2022. The Company anticipates that it will file its Form 10-K as soon as reasonably possible and within the 15-day grace period provided by Rule 12b-25 of the Securities Exchange Act of 1934, as amended

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.
