Listing the 25 most recent filings of the 411 on record.

Ownership and control

Schedule 13D: stake and stated purpose

Filed by holders above 5% of a share class who cannot use the short form. It includes the investor's stated purpose: read it before assuming they seek influence.

  • NIKOLAS P. TSAKOS16.7%Nov 27, 24SCHEDULE 13D/A ↗6 co-filers on this document — the figure is the largest single stake, not their sum.
  • TSAKOS HOLDINGS FOUNDATION10.7%May 16, 25SCHEDULE 13D/A ↗3 co-filers on this document — the figure is the largest single stake, not their sum.

Schedule 13G: short-form filing

The short form, for holders who meet specific requirements: institutional investors, passive investors without a control purpose, or exempt investors. Asset managers and index funds usually file it.

  • CastleKnight Master Fund LP4.1%Dec 31, 25SCHEDULE 13G/A ↗6 co-filers on this document — the figure is the largest single stake, not their sum. · 1 earlier filing

Structured 13D/G data starts 2023-12, when the SEC moved these filings to a machine-readable format. Earlier filings exist but are not parsed here.

Sale intention announced

On Oct 13, Saroglou Georgios filed notice of intent to sell up to $266K. That is about 0.02% of shares outstanding.

A notice is not a sale: it may not go ahead, may happen in part, or at a different price.

No sale of theirs is on record yet in Form 4; the 90-day window is still open.

  • No account

    This profile for every company we cover: closing prices with the record's facts on the curve, the SEC file in plain language, insider trades included, and links to its sector and exchange.

  • Pro

    What matters today, with its reason, is free with an account. Pro adds, in the profile, each company's notices and their explanation and the analysis of its insiders; in Radar, all the lenses, which notice each candidate carries, filters by notice type and «no dilution», and the cycle cohort filter; and in Watchlist, more companies and notice changes with their reason.

  • Pro+

    Adds the Lab: test a hypothesis on comparable cohorts before reusing it; and bring your lenses to Radar.

Are the prices real time?

No. It is one close per session, from the provider and with the date shown on the profile; it does not update during the trading day.

Which SEC documents appear here?

Those filed with the SEC by the company, its insiders and its major shareholders, within our coverage: periodic reports (10-K, 10-Q, 20-F), material events (8-K), proposed sale notices (Form 144), insider transactions (Form 4) and stakes above 5% (13D/13G). Each links to the original on EDGAR.

Why does a European company show no SEC records?

It depends on the company: some European issuers file a 20-F or 6-K with the SEC and others don't. The profile shows whatever is on record; when there is nothing, it says so rather than guessing why. Europe does not yet have a common filing archive like EDGAR in the United States. The EU will open its own, ESAP, in July 2027 (managers' transactions arrive in January 2028), and we plan to add it once it is available.

One close per session. The record in plain language. Its sector and its market one link away. Your judgment when deciding.
