Explanation of Responses:

1. This represents the difference between the number of stock appreciation rights (SARs) exercised (16,950) and the number of shares issued as a result of the exercise (6,490). Each SAR represents the right, upon exercise, to receive a number of shares of Common Stock equal in value to the amount, if any, by which the fair market value of Common Stock (as determined on the date of the exercise) exceeds the exercise price.

2. This represents the withholding of shares of Common Stock to satisfy tax withholding liability associated with the exercise of the SARs that was reported in this Form 4.

3. The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $675.00 to $675.65, inclusive. The Reporting Person undertakes to provide to Cable One, Inc., any security holder of Cable One, Inc., or the staff of the Securities and Exchange Commission, upon request, full information regarding the shares sold at each separate price within the ranges set forth in this footnote, and in footnotes (4) to (7), inclusive to this Form 4.
