On April 8, 2015, Lions Gate Entertainment Corp. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with J.P. Morgan Securities LLC, as underwriter (the “Underwriter”), and certain investment funds affiliated with MHR Management LLC (the “Selling Shareholders”) in connection with a registered underwritten secondary public offering (the “Offering”) of the Company’s common shares, no par value (the “Shares”). Subject to the terms of the Underwriting Agreement, the Selling Shareholders agreed to sell to the Underwriter, and the Underwriter agreed to purchase from the Selling Shareholders, an aggregate of 10,000,000 Shares. The Selling Shareholders also granted the Underwriter a 30-day option to purchase up to an additional 1,500,000 Shares. The Company will not receive any proceeds from the sale of Shares in the Offering.

The shares to be sold in the Offering have been registered pursuant to the automatically effective registration statement on Form S-3 (Registration Statement No. 333-203280) (the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) on April 7, 2015.

The Underwriting Agreement is also filed with reference to, and is hereby incorporated by reference into, the Registration Statement.

Any offer, if at all, will be made only by means of the prospectus forming a part of the effective Registration Statement.

In addition, on April 8, 2015, the Company issued a press release announcing the pricing of the Offering. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference into this Item 8.01.
