UK short positions the FCA published under this name: 15 companies and 240 disclosures between 13 Jan 2015 and 18 Dec 2025. Each figure is that position as a percentage of the company's issued share capital, not a money value, and percentages are not comparable or summable across companies.
This name still appears in the European registers, which do publish holders: current positions for Whitebox Advisors LLC. The two datasets are kept separate and never combined.

Frequently asked questions
- Which UK companies did Whitebox Advisors LLC short?
- The FCA's named register recorded Whitebox Advisors LLC against 15 UK companies between 2015 and 2026, across 240 disclosures. No position was still open when the register closed on 10 Jul 2026.
- Is this list current?
- No. It is a frozen archive. The FCA stopped publishing position-holder names on 13 July 2026 and now publishes one anonymous aggregate per company per day, so no new named UK disclosure exists after 10 Jul 2026. Today's UK figures are on each company's own page.
- Was this the whole of Whitebox Advisors LLC's UK short book?
- No. Only net short positions of 0.5% or more of a company's issued share capital were published with the holder's name. Smaller positions were reported to the FCA privately and never appeared in the register, so the archive is a floor, not a full book.
