Warning signs in its filings
Problems the company itself reported to the SEC, in its own words.
2 serious warning signs in HeartSciences’ 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 23 Jul 2026, plus the 10-Q filed 14 Sep 2026 and 10 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.
“These factors raise substantial doubt regarding the Company's ability to continue as a going concern.”
Show the full paragraph
The Company has incurred losses each year since inception and has experienced negative cash flows from operations in each year since inception. At July 31, 2026 and April 30, 2026 , the Company had an accumulated deficit of $ 88.4 million and $ 85.3 million, respectively. These factors raise substantial doubt regarding the Company's ability 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 the most recent evaluation of internal controls over financial reporting, our Chief Executive Officer (our principal executive officer) and our Chief Financial Officer (our principal financial officer) determined that our disclosure controls and procedures were not effective as of July 31, 2026 as a result of identified material weaknesses in our internal control over financial reporting.”
Show the full paragraph
The Company has adopted and maintains disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed in the reports filed under the Exchange Act, such as this Quarterly Report on Form 10-Q, is collected, recorded, processed, summarized and reported within the time periods specified in the rules of the SEC. The Company's disclosure controls and procedures are also designed to ensure that such information is accumulated and communicated to management to allow timely decisions regarding required disclosure. Based upon the most recent evaluation of internal controls over financial reporting, our Chief Executive Officer (our principal executive officer) and our Chief Financial Officer (our principal financial officer) determined that our disclosure controls and procedures were not effective as of July 31, 2026 as a result of identified material weaknesses in our internal control over financial reporting. The identified material weaknesses were as follows: (i) lack of proper approval processes and review processes and documentation for such reviews; (ii) we did not maintain sufficient U.S. GAAP and SEC accounting resources commensurate with those required of a public company; and (iii) insufficient number of staff to maintain optimal segregation of duties and levels of oversight. We have taken and continue to take remedial steps to improve our internal controls over financial reporting, which includes designing and implementing effective processes and controls over significant accounts and disclosure, and the preparation of account reconciliations and review of journal entries. Our Chief Financial Officer frequently attends continuing education for updates on accounting policies and procedures. We cannot assure you that these measures will significantly improve or remediate the material weaknesses described above. Management is monitoring the effectiveness of these and other processes, procedures and controls and will make any further changes deemed appropriate. We are committed to ensuring that our internal controls over financial reporting are designed and operating effectively. Management believes the foregoing actions will effectively remediate the material weaknesses, however, our material weaknesses will not be considered remediated until controls are in place for a period of time, the controls are tested, and management concludes that the controls are properly designed and operating effectively.

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.
