Warning signs in its filings

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

1 serious warning sign in Calumet’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 Feb 2026, plus the 10-Q filed 7 Aug 2026 and 9 later 8-Ks.

  • Its past accounts can't be relied on

    Serious

    It told the SEC its earlier accounts should no longer be relied on, usually because they contained errors.

    8-K Item 4.02 filed 7 Nov 2025: the company said its earlier financial statements should no longer be relied on.

    From an 8-K filed 7 November 2025: Previously issued accounts should no longer be relied on. Open 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.
  • It isn't cheap on profits: 150.5× 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
