Each restricted stock unit represents a contingent right to receive one share of Series C GCI Group Common Stock.

On July 14, 2025, Liberty Broadband Corporation completed the spin-off of the Issuer (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 the Issuer'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.

Remarks:

The number of shares of the Issuer's Series C GCI Group Common Stock subject to each Issuer restricted stock unit was determined on July 17, 2025 in a manner designed to preserve the value associated with the original awards prior to the Spin-Off. Otherwise, such Issuer restricted stock units are generally subject to the same terms and conditions applicable to the Liberty Broadband restricted stock units, and such adjustments were approved by the Issuer's board of directors pursuant to Rule 16b-3.
