Explanation of Responses:

( 1 )The transactions reported on this Form 4 relate to the spin-off of the Issuer from the Reporting Person effective July 14, 2025. To effect the spin-off, the issued and outstanding common stock of the Issuer, consisting of 1,000 shares of common stock, all of which were held by the Reporting Person, were reclassified into 3,650,938 shares of the Issuer's Series A GCI Group common stock ("GLIBA"), 400,806 shares of the Issuer's Series B GCI Group common stock ("GLIBB"), and 24,646,041 shares of the Issuer's Series C GCI Group common stock ("GLIBK" and, together with GLIBA and GLIBB, "GCI Group Common Stock") (collectively, the "Reclassification"). ( 2 )Immediately following the Reclassification, in such spin-off, the Reporting Person distributed to holders of record of the Reporting Person's common stock, 0.20 of a share of the corresponding series of GCI Group Common Stock, with cash (without interest) paid in lieu of any fractional shares of GCI Group Common Stock, after aggregating all fractional shares of GCI Group Common Stock, separately by series. As a result of the foregoing transactions, the Issuer was spun-off from the Reporting Person and the Reporting Person ceased to have an equity interest in the Issuer and thus is no longer subject to the obligations of Section 16 of the Securities Exchange Act of 1934.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
