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.
2 serious warning signs in Cosmos Health’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 15 Apr 2026, plus the 10-Q filed 18 Aug 2026 and 5 later 8-Ks.
Doubt it can keep going
SeriousThe company or its auditor warned it may not have enough money to last the next year.
“This uncertainty, along with the Company's history of losses, indicates that there is substantial doubt about the Company's ability to continue as a going concern within one year after the date that the financial statements are issued.”
Show the full paragraph
The Company expects to continue to incur significant operating losses for the foreseeable future. If the Company is unable to secure additional capital, it may be required to take additional measures to reduce costs in order to conserve its cash in amounts sufficient to sustain operations and meet its obligations. These measures could cause significant delays or entirely prevent the Company's continued efforts to commercialize its current or future products, which are critical to the realization of its business plan and the future operations of the Company. This uncertainty, along with the Company's history of losses, indicates that there is substantial doubt about the Company's ability to continue as a going concern within one year after the date that the financial statements are issued. The accompanying condensed consolidated financial statements do not include any adjustments that may be necessary should the Company be unable to continue as a going concern.

Weak checks on its own accounts
SeriousThe 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 upon that evaluation, the Principal Executive Officer and the Principal Financial Officer have concluded that, as of the end of the period covered by this report, the Company’s disclosure controls and procedures were ineffective due to material weaknesses stated below:”

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.
