1 serious warning sign in Peraso’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 30 Mar 2026, plus the 10-Q filed 13 Aug 2026 and 11 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.

    “As a result of the Company’s expected operating losses and cash burn for the foreseeable future, as well as recurring losses from operations, management has concluded that there is substantial doubt regarding the Company’s ability to continue as a going concern for a period of at least 12 months beyond the filing of this Quarterly Report on Form 10-Q.”
    Show the full paragraph
    The Company expects to continue to incur operating losses for the foreseeable future as it secures additional customers and continues to invest in the commercialization of its products. The Company will need to increase revenues substantially beyond levels that it has attained in the past in order to generate sustainable operating profit and sufficient cash flows to continue doing business without raising additional capital from time to time. As a result of the Company’s expected operating losses and cash burn for the foreseeable future, as well as recurring losses from operations, management has concluded that there is substantial doubt regarding the Company’s ability to continue as a going concern for a period of at least 12 months beyond the filing of this Quarterly Report on Form 10-Q. In addition, the Company’s independent registered public accounting firm, in its report on the Company’s consolidated financial statements for the year ended December 31, 2025, expressed substantial doubt about the Company’s ability to continue as a going concern. These condensed consolidated financial statements do not include any adjustments that might result from this uncertainty. There can be no assurance that the Company can raise additional capital, whether in the form of debt or equity financing, that will be sufficient or available and, if available, that such capital will be offered on terms and conditions acceptable to the Company. The Company’s primary focus is producing and selling its products. If the Company is unsuccessful in these efforts, it will need to implement additional cost reduction strategies, which could further affect its near- and long-term business plan. These efforts may include, but are not limited to, reducing headcount and curtailing business activities.

  • One big customer

    Worth knowing

    One customer brings in a big share of sales: 29% last year. Losing that customer would hurt.

    “During the year ended December 31, 2025, five customers accounted for 10% or more of our net revenues, including UI Limited at 29% and F5/Flextronics, Tachyon and Alltek at 13% each and Ikeja at 12%.”

    From the 10-K filed 30 March 2026, Item 1. Business. 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.
