Warning signs in its filings
Problems the company itself reported to the SEC, in its own words.
1 serious warning sign in AMC Robotics’ filings.
We look for five warning signs: doubt it can keep going, weak checks on its own accounts, a notice that its past accounts can't be relied on, a change of auditor, and one customer bringing in a big share of sales. We don't check lawsuits, investigations or debt yet.
We checked the auditor's report, internal controls, restatement notices, auditor changes and big customers in the 10-K filed 20 Apr 2026, plus the 10-Q filed 14 Aug 2026 and 7 later 8-Ks.
Weak checks on its own accounts
SeriousThe company said its checks on its own accounts did not work at the end of its latest quarter. Mistakes could slip into the numbers.
“Based on this evaluation, our Principal Executive Officer and Principal Financial Officer concluded that our disclosure controls and procedures were not effective as of June 30, 2026 due to the material weaknesses in our internal control over financial reporting described below.”
From the 10-Q filed 14 August 2026, Part I, Item 4. Controls and Procedures. Read it in the filing
One big customer
Worth knowingOne customer brings in a big share of sales: 52% last year. Losing that customer would hurt.
“For the fiscal year ended December 31, 2025, one customer, Kami Vision Incorporated (“Kami”), a related party to AMC, contributed approximately 52% of AMC’s revenue and accounted for 79% of AMC’s accounts receivable at December 31, 2025.”
From the 10-K filed 20 April 2026, Item 1A. Risk Factors. Read it in the filing
A 10-K is the yearly report every US company files with the SEC. An 8-K is a short notice of a big event.
