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.

2 serious warning signs in Pelthos Therapeutics’ 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 19 Mar 2026, plus the 10-Q filed 13 Aug 2026 and 8 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 upon such evaluation, our principal executive and financial officers have concluded that, because of the material weakness in our internal control over financial reporting discussed below, our disclosure controls and procedures were not effective as of such date at the reasonable assurance level.”
    Show the full paragraph
    As of June 30, 2026, our management, with the participation of our principal executive and financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based upon such evaluation, our principal executive and financial officers have concluded that, because of the material weakness in our internal control over financial reporting discussed below, our disclosure controls and procedures were not effective as of such date at the reasonable assurance level.

  • 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 13 Aug 2026: the company said its earlier financial statements should no longer be relied on.

    From an 8-K filed 13 August 2026: Previously issued accounts should no longer be relied on. Open the filing

  • Changed auditor

    Worth knowing

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

    “On May 16, 2026, the Audit Committee (the “Audit Committee”) of the Board of Directors (the “Board”) of Pelthos Therapeutics Inc. (the “Company”) approved the dismissal of CBIZ CPAs P.C. (“CBIZ”), as the Company’s independent registered public accounting firm.”

    From an 8-K filed 21 May 2026: Change of auditor. Read it in the filing

  • One big customer

    Worth knowing

    One customer brings in a big share of sales: 35% last year. Losing that customer would hurt.

    “In addition, for the year ended December 31, 2025, these three wholesalers accounted for 89% of gross revenue at 35%, 28% and 26%, respectively.”

    From the 10-K filed 19 March 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.

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.
