Capital spending looks too small to be complete, so we leave free cash flow out.

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

Warning signs in its filings

Problems the company itself reported to the SEC, in its own words.

1 serious warning sign in Kodiak Sciences’ 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 13 Aug 2026 and 4 later 8-Ks.

  • Doubt it can keep going

    Serious

    The company or its auditor warned it may not have enough money to last the next year.

    “• Our financial condition raises substantial doubt about our ability to continue as a going concern.”

    From the 10-Q filed 13 August 2026, Part I. 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

A big holder just moved. The deep dive shows what the business is worth.
