Warning signs in its filings

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

2 serious warning signs in Exozymes’ 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 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.

    “Although the Company believes it has sufficient working capital for the near term, management believes that there remains substantial doubt about its ability to continue as a going concern due to anticipated funding shortfalls and the Company’s pre-revenue status.”
    Show the full paragraph
    These condensed unaudited consolidated financial statements have been prepared on a going concern basis, which implies that the Company will continue to realize its assets and discharge its liabilities in the normal course of business. The Company incurred net losses of $ 5,248,861 and $ 4,216,707 during the six months ended June 30, 2026 and 2025, respectively, and used cash for operations of $ ( 3,164,719 ) and $ ( 2,671,532 ) for the six months ended June 30, 2026 and 2025, respectively. Although the Company believes it has sufficient working capital for the near term, management believes that there remains substantial doubt about its ability to continue as a going concern due to anticipated funding shortfalls and the Company’s pre-revenue status. The Company’s ability to meet its long-term liabilities and obligations depends on securing additional financial support, whether through continued shareholder funding, raising equity or debt financing, or ultimately achieving profitable operations. These financial statements do not include any adjustments to the recoverability and classification of recorded asset amounts or the classification of liabilities that may be necessary should the Company be unable to continue as a going concern.

  • 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, and as a result of the material weaknesses in internal control over financial reporting described below, the Chief Executive Officer and VP of Finance concluded that, as of June 30, 2026, the disclosure controls and procedures were not effective at the reasonable assurance level.”
    Show the full paragraph
    The Company, with the participation of the Chief Executive Officer and VP of Finance, evaluated, as of the end of the period covered by this Quarterly Report on Form 10-Q, the effectiveness of the disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act). Based on that evaluation, and as a result of the material weaknesses in internal control over financial reporting described below, the Chief Executive Officer and VP of Finance concluded that, as of June 30, 2026, the disclosure controls and procedures were not effective at the reasonable assurance level. In light of this fact, the Company has performed additional analyses, reconciliations, and other post-closing procedures and has concluded that, notwithstanding the material weaknesses in the internal control over financial reporting, the condensed unaudited consolidated financial statements for the periods covered by and included in this Quarterly Report on Form 10-Q fairly state, in all material respects, the financial position, results of operations and cash flows for the periods presented in conformity with GAAP.

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.
