Questions about who owns Newmarket Corp
Who owns Newmarket Corp?
On this page, 2 holders' latest ownership filings report 5% or more of Newmarket Corp: Bruce C. Gottwald (10.1%, Schedule 13D/A, filed 2026-01-07) and The London Company (5.87%, Schedule 13G/A, filed 2025-08-14).
Who are the largest shareholders of Newmarket Corp?
By the share each holder's latest filing reports, the largest holders of Newmarket Corp on this page are Bruce C. Gottwald (10.1%) and The London Company (5.87%).
When did Bruce C. Gottwald buy into Newmarket Corp?
The filings give report dates, not purchase dates. The earliest filing from Bruce C. Gottwald on this page is the Schedule 13D/A, filed 2026-01-07, reporting 10.1%. That earliest filing is itself an amendment, which updates an earlier report.
Is this an audit or a full list?
Neither. The ownership list on this page covers only Schedule 13D and 13G filings, which holders make once they own 5% or more of a class of shares (an amendment can report a stake that has since fallen below 5%); 5 such filings are shown here. It is not an audit and not a full cap table: holders who never reached 5% are not listed, and a stake can change after its latest filing.

Where this comes from
Anyone who comes to own more than 5% of a class of a listed company's voting shares has to tell the SEC. A holder who may seek to change or influence the company files Schedule 13D, and has to say in Item 4, "Purpose of Transaction", what it intends to do. A holder with no such intent, such as many index and passive funds, may file the shorter Schedule 13G. Both are amended when the stake changes, including when it falls below 5%.
Every row here is one of those filings, linked to the filing itself. Percentages and share counts are exactly as the holder filed them, for the holder the filing names; an amendment showing a lower figure is shown as filed. Item 4 text is quoted word for word. Where a 13D's Item 4 contains a sentence stating a definite intent to influence the company, that sentence is marked and quoted; the page does not describe the holder or its motives beyond the words it filed. Nothing here is investment advice.
