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.
1 serious warning sign in AirJoule Technologies’ 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 31 Mar 2026, plus the 10-Q filed 14 Aug 2026 and 4 later 8-Ks.
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 on this evaluation, our principal executive officer and principal financial officer concluded that, as of June 30, 2026, our disclosure controls and procedures were not effective at the reasonable assurance level due to the material weakness in our internal control over financial reporting described below.”
Show the full paragraph
Our management, with the participation of our principal executive officer and principal financial officer, evaluated, as of the end of the period covered by this Quarterly Report on Form 10-Q, the effectiveness of our disclosure controls and procedures. Based on this evaluation, our principal executive officer and principal financial officer concluded that, as of June 30, 2026, our disclosure controls and procedures were not effective at the reasonable assurance level due to the material weakness in our internal control over financial reporting described below.
From the 10-Q filed 14 August 2026, Part I, Item 4. Controls and Procedures. Read it in the filing
Changed auditor
Worth knowingThe company changed its auditor (the firm that checks its books) in the last two years.
“On May 20, 2025, the Audit Committee of the Board of Directors (the “ Audit Committee ”) of AirJoule Technologies Corporation (the “ Company ”) approved the appointment of Deloitte & Touche LLP (“ Deloitte ”) as the Company’s new independent registered public accounting firm for the fiscal year ending December 31, 2025 and notified BDO USA, P.C. (“ BDO ”) of its dismissal as the Company’s independent registered public accounting firm, effective as of May 20, 2025.”
From an 8-K filed 27 May 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.
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.
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
- Every number footnoted to the filing it came from
Your first deep dive is free.
