[Form 4] Liberty Broadband Corporation Series A Cumulative Redeemable Preferred Stock Insider Trading Activity

Rhea-AI Filing Summary

Form 4 snapshot: Director Julie D. Frist reported technical adjustments to her Liberty Broadband Corp. (LBRDK) Series C common-stock options on 07/17/2025. The changes stem from the 07/14/2025 spin-off of GCI Liberty, which required proportional revisions to every outstanding option grant.

Five new option positions totalling 25,601 shares were credited at revised strike prices of $71.17‒$153.58, while five legacy awards covering 23,832 shares were cancelled. Net result: an incremental 1,769 additional options; all awards are fully exercisable and expire between 12/07/2027 and 12/11/2030. No non-derivative shares were reported.

The transaction code “J” confirms these were corporate-action adjustments approved under Rule 16b-3; there was no open-market buying or selling and no cash changed hands. Consequently, the insider’s economic exposure is effectively unchanged, and the filing carries minimal direct valuation impact for shareholders.

Insights

Financial Analyst

TL;DR: Spin-off-driven option recalibration; no real buying/selling—neutral.

The board’s Rule 16b-3 action merely resets strike prices and option counts so Ms. Frist’s intrinsic value mirrors pre-spin conditions. Net 1,769 extra options is immaterial relative to Liberty Broadband’s 150 m+ share count and does not signal bullish or bearish sentiment. Because no cash was paid and all options remain fully vested, dilution risk and insider-motivation dynamics are unchanged. Investors can treat the filing as bookkeeping, not a trade signal.

Explanation of Responses:

1. On July 14, 2025, Liberty Broadband Corporation completed the spin-off of GCI Liberty, Inc. (the "Spin-Off"), which was effected by the distribution to each holder of its common stock as of 5:00 p.m., New York City time, on June 30, 2025, of 0.20 of a share of GCI Liberty, Inc.'s Series A, Series B and Series C GCI Group common stock for each whole share of the corresponding series of Liberty Broadband Corporation's common stock, with cash (with no interest) paid in lieu of fractional shares. In connection with the Spin-Off, all stock options held by the Reporting Person in the Issuer's Series C Common Stock were adjusted in a manner designed to preserve the value associated with the original awards prior to the Spin-Off. The number of shares and the exercise price for each adjusted award were determined on July 17, 2025. Otherwise, such award remains subject to the terms and conditions of the corresponding original award.

2. This option award is fully exercisable.

Remarks:

The adjustments described above were approved by the Issuer's board of directors pursuant to Rule 16b-3 under the Securities Exchange Act of 1934, as amended.
