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. 2 things 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 3 Mar 2026, plus the 10-Q filed 11 Aug 2026 and 7 later 8-Ks.
Changed auditor
Worth knowingThe company changed its auditor (the firm that checks its books) in the last two years.
“On October 11, 2024, the Audit Committee (the “Audit Committee”) of the Board of Directors of CPS Technologies Corp. (the “Company”) dismissed Wolf & Company, P.C. (“Wolf”) as the Company’s independent registered public accounting firm, effective with the completion of the Review of the Company’s Form 10-Q for the quarter ended September 28, 2024.”
From an 8-K filed 16 October 2024: Change of auditor. Read it in the filing
One big customer
Worth knowingOne customer brings in a big share of sales: 39% last year. Losing that customer would hurt.
“In 2025, our three largest customers accounted for 39%, 13%, and 12% of revenues, respectively.”
From the 10-K filed 3 March 2026, Item 1. Business. 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.
- 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
