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 Mar 2026, plus the 10-Q filed 3 Aug 2026 and 5 later 8-Ks.

  • Changed auditor

    Worth knowing

    The company changed its auditor (the firm that checks its books) in the last two years.

    “On September 19, 2025, the Audit Committee (the “Committee”) of the Board of Directors of American Bitcoin Corp. (the “Company”) dismissed RBSM LLP (“RBSM”) as the Company’s independent registered public accounting firm.”

    From an 8-K filed 25 September 2025: Change of auditor. 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.
