Warning signs in its filings

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

1 serious warning sign in Comtech Telecommunications’ 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 10 Nov 2025, plus the 10-Q filed 15 Jun 2026 and 10 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 on this evaluation, we concluded that our disclosure controls and procedures were not effective as of April 30, 2026, as a result of the material weaknesses in our internal control over financial reporting discussed below.”

    As of the end of the period covered by this Quarterly Report on Form 10-Q, an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934), was carried out by us under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer. Based on this evaluation, we concluded that our disclosure controls and procedures were not effective as of April 30, 2026, as a result of the material weaknesses in our internal control over financial reporting discussed below.

    From the 10-Q filed 15 June 2026, Part I, Item 4. Controls and Procedures. 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.
