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 warning signs we check for were found.

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 Feb 2026, plus the 10-Q filed 26 Aug 2026 and 6 later 8-Ks.

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.

What could go wrong

Cheap for a reason is the question the numbers cannot answer.

Whether the price already reflects the risks is what the deep dive is for.

What changed in the risks this year

Companies must list what could hurt them each year. These are the parts that changed since last year’s report.

  • We may have exposure to greater than anticipated tax liabilities, which could harm our business.

    Could happen
    While the One Big Beautiful Bill Act (“OBBBA”) did not result in our being subject to the Corporate Alternative Minimum Tax (“CAMT”) for the current year, future changes in our financial results, business operations, or the interpretation and application of OBBBA provisions could cause us to become subject to CAMT in subsequent periods, which may materially increase our effective tax rate. In addition, on February 18, 2026, the U.S. Department of the Treasury and the Internal Revenue Service released guidance addressing adjustments to adjusted financial statement income (AFSI) under CAMT related to domestic research and development expenditures capitalized under Section 174. We believe the guidance is intended to mitigate certain book-tax timing differences associated with the capitalization and amortization of domestic research and development expenditures. Although the guidance does not impact the current fiscal year, it could affect our CAMT calculations in future periods, and we are evaluating its potential impact.

  • Our sales to government entities and other government contractors are subject to a number of additional challenges and risks.

    Could happen
    Additionally, foreign government initiatives intended to reduce reliance on non-domestic technology may cause foreign governmental agency customers to stop using our solutions, decrease the profitability of sales to such customers, or make it less likely that we are able to sell our solutions to other foreign governmental agencies.
    Read more
  • Our security measures, and those of third parties with whom we work, have been compromised in the past and may be compromised in the future. If our security measures are compromised in the future or if our information technology fails, this could harm our reputation, expose us to significant fines and liability, impair our sales, and harm our business. In addition, if our products and services are perceived as not being secure, this could result in customers and users curtailing or ceasing their use of our products, us incurring significant liabilities, and our business being harmed.

    Could happen
    Our customers may place certain security obligations on us. For example, some of our customers may be subject to the EU’s Digital Operational Resilience Act (DORA) and similar UK regulatory requirements on operational resilience. These laws may obligate our customers to impose contractual provisions on us, including certain mandatory third-party risk management provisions. If we fail to materially comply with these contractual requirements, we may be subject to investigations, audits or other adverse consequences.

  • Zoom Phone is subject to U.S. federal and international regulation, and other products we may introduce in the future may also be subject to U.S. federal, state, or international laws, rules, and regulations. Any failure to comply with such laws, rules, and regulations could harm our business and expose us to liability.

    Could happen
    On March 12, 2025, the FCC opened a proceeding to begin the process of identifying FCC rules, regulations, and guidance documents for elimination or modification to alleviate unnecessary regulatory burdens and eliminating or modifying such rules. This proceeding could result in substantial changes to the FCC’s rules, including the elimination or modification of rules that impose burdens on us and rules that benefit us, including those that prevent anticompetitive behavior by competitors. We cannot predict which rules will be affected by this initiative, when the FCC will act, or the impact of any elimination or modification of existing FCC rules on our operations or business.

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
