1 serious warning sign in IP Strategy Holdings’ 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 14 Apr 2026, plus the 10-Q filed 20 May 2026 and 5 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.

From the 10-Q filed 20 May 2026, Part I, Item 4. Controls and Procedures. 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.
