Why they said they were late

ACM Research, Inc. (the “Company”) had completed its Annual Report on Form 10-K for the fiscal year ended December 31, 2022 (the “10-K”), and instructed its third party filing service to file the 10-K with the Securities and Exchange Commission prior to the submission deadline on March 1, 2023. Due to technical problems with the filing service’s XBRL tagging software, it was unable to timely file the 10-K. The Company filed the 10-K shortly after the submission deadline on March 1, 2023

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.
