On November 29, 2012, Nexstar Broadcasting Group, Inc. (the "Company") entered into an underwriting agreement (the "Underwriting Agreement") with Credit Suisse Securities (USA) LLC, Wells Fargo Securities, LLC and UBS Securities LLC, as representatives for the underwriters named therein (collectively, the "Underwriters"), and ABRY Broadcast Partners II, L.P. and ABRY Broadcast Partners III, L.P. (collectively, the "Selling Stockholders"), pursuant to which the Selling Stockholders agreed to sell 8,000,000 shares of the Company's Class A common stock, par value $0.01 per share (the "Common Stock"), to the Underwriters at a public offering price of $9.25 per share (the "Firm Shares"). The Company did not receive any of the proceeds from the Selling Stockholders' sale of the Firm Shares. The offering of the Firm Shares closed on December 5, 2012.

In addition, the Selling Stockholders also provided the Underwriters with a 30-day option from the date of the preliminary prospectus supplement to purchase up to an additional 1,200,000 shares of Common Stock. This option has not been exercised as of the date of this filing.

The Underwriting Agreement includes customary representations, warranties and covenants by the Company and the Selling Stockholders. It also provides that the Company and the Selling Stockholders will indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933 (the "Securities Act"), or contribute to payments the Underwriters may be required to make because of any of those liabilities.

These representations and warranties of the parties contained in the Underwriting Agreement have been made solely for the benefit of the other parties to the Underwriting Agreement and:

• should not be treated as categorical statements of fact, but rather as a way of allocating the risk to one of the parties if those statements prove to be inaccurate

• may have been qualified in the Underwriting Agreement by disclosures that were made to the other party in connection with the negotiation of the Underwriting Agreement;

• may apply contract standards of "materiality" that are different from "materiality" under the applicable securities laws; and

• were made only as of the date of the Underwriting Agreement or such other date or dates as may be specified in the Underwriting Agreement.

The foregoing summary of the Underwriting Agreement is qualified by reference to the full text of the Underwriting Agreement, which is filed as Exhibit 1.1 hereto and incorporated herein by reference.

On December 5, 2012, the Company issued a news release announcing the closing of the previously announced underwritten secondary offering of Common Stock by the Selling Stockholders. A copy of the news release is attached hereto as Exhibit 99.1 and incorporated herein by reference.
