Liberty Broadband (LBRDK) 10% Owner John C. Malone Sells Shares

What Happened

John C. Malone (reported as a 10% owner) exercised multiple in‑the‑money derivative positions and disposed of large blocks of Liberty Broadband shares on August 18–19, 2026. Two option exercises (66,000 shares each) showed an $88.37 price, producing roughly $5.83M per exercise (total ≈ $11.66M). In connection with the August 19, 2026 merger with Charter, Malone also had numerous dispositions to the issuer and other derivative-settlement entries affecting millions of shares (amounts reported as dispositions to the issuer or adjustments; dollar values not stated).

Key Details

• Transaction dates: Aug 18, 2026 and Aug 19, 2026. Two exercises reported at $88.37 for 66,000 shares each (≈ $5,832,295 each).
• Major dispositions on Aug 19, 2026: multiple “Disposition to the issuer (D)” entries totaling several million shares (specific dollar values not reported).
• Derivative activity: several exercises (X), expirations (E), and “other acquisition/disposition (J)” entries tied to previously entered zero‑cost collars from 2019 and 2021.
• Shares owned after transaction: not specified in the provided summary of the filing.
• Filing timeliness: Form 4 filed Aug 20, 2026 for transactions dated Aug 18–19, 2026 — filed within the typical two‑business‑day window.
• Footnotes of note:
  • 2019 and 2021 transactions were “zero‑cost collars” (no net premium exchanged) and are divided into multiple components that matured sequentially (F6, F10, F7, F11).
  • Footnotes F1–F2: Malone physically settled components of the 2019 Transaction on Aug 18 and Aug 19, 2026.
  • Merger effects (F3, F8, F9): at the effective time of the Merger each Series C share was converted into 0.2360 shares of Charter Class A common stock (with fractional shares cashed out) and the dealer counterparty adjusted collars and strikes accordingly.
  • F5: Malone disclaims beneficial ownership of certain shares owned by his spouse.

Context

• These transactions stem largely from derivative (zero‑cost collar) arrangements entered in 2019 and 2021. A zero‑cost collar involves selling call options and buying put options so that at expiration only one side can be in the money; settlement can be cash or physical. Malone elected physical settlement for at least some components, triggering exercises, expirations and transfers tied to the Charter merger mechanics.
• As a reported 10% owner (not a company executive), Malone’s moves reflect large, structured derivative settlements and merger adjustments rather than routine open‑market trading by an officer. The filings are factual records of exercises, expirations and merger‑related conversions — they do not themselves explain motivation.
