Warning signs in its filings

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

2 serious warning signs in Leslie'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 18 Dec 2025, plus the 10-Q filed 12 Aug 2026 and 9 later 8-Ks.

  • Doubt it can keep going

    Serious

    The company or its auditor warned it may not have enough money to last the next year.

    “These conditions and events raise substantial doubt about the Company’s ability to continue as a going concern.”
    Show the full paragraph
    We believe that the persistently challenging retail environment, including observed reductions and delays in consumer spending in the pool and spa care industry, along with consumers’ increased price sensitivity after years of persistent inflation, have significantly impacted the Company’s performance. Historically, we have primarily relied on cash generated from operating activities in our third and fourth fiscal quarters to fund our day-to-day operations and service our debt. Although we continue to pursue our strategic initiatives, including ongoing cost optimization efforts, the timing and realization of our strategy cannot guarantee sufficient cash flow will be generated to meet the Company’s debt obligations and operating costs. These conditions and events raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans to address our more immediate challenges may include the following:

  • 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 (Principal Executive Officer) and Chief Financial Officer and Treasurer (Principal Financial Officer) have concluded that our disclosure controls and procedures were not effective as the material weaknesses in our internal control over financial reporting disclosed in our Annual Report on Form 10-K for the fiscal year ended October 4, 2025 were not yet remediated as of July 4, 2026.”
    Show the full paragraph
    Our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e)) are designed to ensure that information required to be disclosed by us in reports we file or submit under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized, and reported within the appropriate time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer and Treasurer, as appropriate, to allow timely discussions regarding required disclosure. We, under the supervision of and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer and Treasurer, have evaluated the effectiveness of our disclosure controls and procedures as of July 4, 2026. Based on that evaluation, our Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer and Treasurer (Principal Financial Officer) have concluded that our disclosure controls and procedures were not effective as the material weaknesses in our internal control over financial reporting disclosed in our Annual Report on Form 10-K for the fiscal year ended October 4, 2025 were not yet remediated as of July 4, 2026.

  • Changed auditor

    Worth knowing

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

    “In addition, on January 27, 2026, the Audit Committee approved the dismissal of Ernst & Young LLP (“EY”) as the Company’s independent registered public accounting firm, effective upon the completion of EY’s interim review of the Company’s financial statements for the quarter ended January 3, 2026.”

    From an 8-K filed 30 January 2026: 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.

  • 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

The company just told the SEC about a big change. The deep dive shows what it means for the price you pay.
