Dear AMC Networks Inc. Stockholder:

Enclosed please find a replacement Letter of Transmittal and Notice of Guaranteed Delivery in connection with the offer by AMC Networks Inc. to purchase up to $250 million in value of shares of its Class A common stock, par value $0.01 per share (the “Shares”), at a purchase price of not greater than $26.50 nor less than $22.50 per Share (the “Offer”). Please refer to the Offer to Purchase, dated September 16, 2020, as may be amended from time to time, for a more detailed explanation of the Offer.

The Letter of Transmittal and Notice of Guaranteed Delivery previously sent to you inadvertently incorrectly listed $26.90 instead of $25.90 in Section 2 on page 4 of the Letter of Transmittal and Section 2 on page 2 of the Notice of Guaranteed Delivery.
