Watch this stockFree. We tell you when something changes.

This company reports once a year (it is based outside the US), so every figure comes from its annual report for the year to December 2025.

We can't read total debt from the filing, so debt is left out.

Cash flow or capital spending isn't reported, so free cash flow is unknown.

We can't pin down how many shares it has, so we don't rank it.

What insiders did

We have no insider filings for this company yet.

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.

InflaRx doesn’t file a US annual report (10-K), so we haven’t checked it.

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
