Only open-market purchases (SEC code P) and sales (code S) are counted here. Option exercises, vesting/awards, gifts, and shares withheld for taxes are excluded — they are compensation or mechanical, not open-market conviction. Sales may be planned and non-discretionary (e.g. a Rule 10b5-1 plan) and are not necessarily bearish; open-market buying is not a recommendation to buy. Informational only — not financial advice.

Institutional ownership (13F)

5 institutional 13F filers reported holding LBRDK as of 2026-03-31 (quarter-end position, filed within 45 days).

  • Distinct 13F filers 5
  • Reported shares held 7,754,600
  • Reported value $390,056,387

reported quarterly holdings change (2025-12-31 → 2026-03-31): 0 new, 2 increased, 3 decreased, 1 exited. Change counts cover only managers that filed 13F reports in BOTH quarters, derived between two quarter-end snapshots — not same-day trades; a single manager is never said to have "bought" or "sold".

Institutional holdings are quarter-end long positions reported on SEC Form 13F-HR, filed up to 45 days after the quarter ends — they are delayed, are not real-time trades, exclude short positions and most non-US securities, and are not investment advice. Any increase/decrease is a reported change between two quarterly snapshots, not a same-day purchase or sale. These are quarter-end snapshots from the 13F filings on SEC EDGAR, filed within 45 days — not real-time, and any change is a difference between two quarterly reports, not a same-day trade. Informational only — not financial advice.

Short interest (FINRA)

LBRDK had 7,337,946 shares of reported short interest as of the 2026-08-14 FINRA settlement date (delayed, bi-monthly; not real-time).

Short interest as a percent of shares outstanding is not shown for LBRDK because we do not hold a verified share count to divide it by. The reported figures above are unaffected.

  • Reported short interest (shares) 7,337,946
  • Prior settlement (shares) 4,367,337
  • Reported change 68.02%
  • Days to cover (reported) 4.58

Reported to FINRA as of the 2026-08-14 settlement date. Short interest is reported to FINRA and published on a delayed, bi-monthly schedule (as of a settlement date, disseminated roughly eight business days later) — it is NOT real-time, does not cover every venue or all US trading, and is not a short-squeeze prediction or investment advice. Days-to-cover is the value FINRA reports; percent of float is not shown because the source file carries no share-count denominator — where a percent appears it is of shares OUTSTANDING, the larger base, and is therefore a floor on percent of float. Informational only — not financial advice.
