POWER OF ATTORNEY


KNOW ALL MEN BY THESE PRESENTS: that I, Stephen C. Mills,
constitute and appoint James G. Gallagher and Anne G. Kelly
as true and lawful attorney-in-fact, with full power of
substitution and resubstitution, for me and in my name, place
and stead, in any and all capacities to sign any Forms 3, 4 and 5
in accordance with Section 16(a) of the Securities and Exchange
Act of 1934 and the rules thereunder (including any amendments or
exhibits thereto and other forms and reports) that I may be required
to file with the U.S. Securities and Exchange Commission as a result
of my ownership or transactions in securities of AMC Networks Inc.,
granting unto said attorneys-in-fact and agents, and each of them, full
power and authority to do and perform each and every act and thing
required and necessary to be done in and about the foregoing as fully
for all intents and purposes as I might or could do in person, hereby
ratifying and confirming all that said attorneys-in-fact and agents or
any of them, or their or his substitute or substitutes, may lawfully do
or cause to be done by virtue hereof.
I acknowledge that the attorneys-in-fact and agents, each serving in
such capacity as requested herein, are not assuming, nor is AMC Networks
Inc. assuming, any of the responsibilities to comply with Section 16 of
the Securities and Exchange Act of 1934. This power of attorney is not
intended to, and does not, revoke, or in any way affect, any prior power
of attorney that I have executed.

This Power of Attorney shall remain in full force and effect until I no
longer am required to file Forms 3, 4, and 5 with respect to my holdings
of and transactions in securities issued by AMC Networks Inc., unless
earlier revoked by me in a signed writing delivered to the foregoing
attorneys-in-fact.

In Witness Whereof, I have hereunto signed my name on the 12th day of
June, 2024.
