Warning signs in its filings

Problems the company itself reported to the SEC, in its own words.

1 serious warning sign in Andersen Group’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 27 Mar 2026, plus the 10-Q filed 12 Aug 2026 and 5 later 8-Ks.

  • Weak checks on its own accounts

    Serious

    The 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 that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of June 30, 2026, due to the material weaknesses described in Part II, “Item 9A “Controls and Procedures” in the 2025 Annual Report on Form 10-K, which continue to exist as of June 30, 2026.”

    Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of June 30, 2026, due to the material weaknesses described in Part II, “Item 9A “Controls and Procedures” in the 2025 Annual Report on Form 10-K, which continue to exist as of June 30, 2026. For additional information on our disclosure controls and procedures, reference the sections titled "Previously Reported Material Weaknesses in Internal Control Over Financial Reporting" and "Efforts to Address Previously Identified Material Weaknesses" in Part II, Item 9A “Controls and Procedures” of the 2025 Annual Report on Form 10-K.

    From the 10-Q filed 12 August 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.

What could go wrong

  • It owes more than it owns on paper (negative equity). Often that's from borrowing to buy back shares.

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
