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 serious warning signs we check for were found. 1 thing worth knowing.
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 20 Mar 2026, plus the 10-Q filed 11 Aug 2026 and 3 later 8-Ks.
Changed auditor
Worth knowingThe company changed its auditor (the firm that checks its books) in the last two years.
“On July 10, 2025, GrowGeneration Corp. (the “Company”) dismissed Grant Thornton LLP (“Grant Thornton”) as the Company's independent registered public accounting firm.”
From an 8-K filed 14 July 2025: Change of auditor. 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.

- Prices to start buying, buy, and buy hard
- The three things that would make this a mistake
