Warning signs in its filings
Problems the company itself reported to the SEC, in its own words.
1 serious warning sign in T Stamp’s 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 31 Mar 2026, plus the 10-Q filed 13 Aug 2026 and 5 later 8-Ks.
Doubt it can keep going
SeriousThe company or its auditor warned it may not have enough money to last the next year.
“These factors, among others, raise substantial doubt about the ability of the Company to continue as a going concern for 12 months since issuance date.”
Show the full paragraph
The Company’s ability to continue as a going concern in the next twelve months, following the date the unaudited condensed consolidated financial statements were available to be issued, is dependent upon its ability to produce revenues and/or obtain financing sufficient to meet current and future obligations and deploy such to produce profitable operating results. Management has evaluated these conditions and plans to generate revenue and raise capital as needed to satisfy its capital needs. While the negotiation of significant additional revenue is well advanced, it has not reached a stage that allows it to be factored into a going concern evaluation. In addition, although the Company has previously been successful in raising capital as needed and has already made plans to do so as well as restructuring expenses to meet the Company’s cash needs, no assurance can be given that the Company will be successful in its capital raising efforts. These factors, among others, raise substantial doubt about the ability of the Company to continue as a going concern for 12 months since issuance date.
From the 10-Q filed 13 August 2026, Part I, Item 1. Financial Statements. Read it in the filing
One big customer
Worth knowingOne customer brings in a big share of sales: 64.4% last year. Losing that customer would hurt.
“During the year ended December 31, 2025, the Company sold to primarily two customers which made up approximately 83.48 % of total Net revenue, and consisted of 64.36 % and 19.12 % from an S&P 500 Bank and QID, respectively.”
From the 10-K filed 31 March 2026, Item 8. Financial Statements and Notes. 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.
The deep dive
Everything above is arithmetic on public filings. The deep dive reads the last ten years of annual reports, the proxy statements, and the earnings calls, then argues the case the way Buffett, Klarman, and Hohn would, and checks every claim against the source.
