From Form 4 filings: insiders must report trades in their own company's shares within two days.
Warning signs in its filings
Problems the company itself reported to the SEC, in its own words.
None of the serious warning signs we check for were found. 1 thing worth knowing.
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 27 Feb 2026, plus the 10-Q filed 27 Jul 2026 and 8 later 8-Ks.
One big customer
Worth knowingOne customer brings in a big share of sales: 32% last year. Losing that customer would hurt.
“Three customers (all in our CCS segment) individually represented 10% or more of total revenue in 2025 (32%, 14%, and 12%).”
From the 10-K filed 27 February 2026, Item 7. Management's Discussion and Analysis. 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.
What could go wrong
- It isn't cheap on profits: 32.8× operating profit.
Whether the price already reflects the risks is what the deep dive is for.
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.
- What the business is worth, as a range, and the margin of safety at today’s price
- Prices to start buying, buy, and buy hard
- The three things that would make this a mistake
- Every number footnoted to the filing it came from
