Item 8.01. Other Events.

On February 25, 2015, Signature Group Holdings, Inc. (the “Company”) issued a press release announcing the final results of its previously announced completed stapled rights offering (the “Rights Offering”) with respect to its holders of common stock, which expired on February 20, 2015. The Company reported that it received basic subscriptions and requests for oversubscriptions for a total of 17,241,514 shares, and that because 7,899,215 basic subscriptions were received out of maximum offering of 9,751,773 shares, a total of 1,852,558 shares will be issued to fulfill oversubscription requests. The Company also reported that it will allocate the oversubscription shares to the holders who validly exercised oversubscription rights on a pro rata basis, based on such holders’ common stock ownership prior to exercising subscription rights and up to the level of subscription payments received from such holders.

As reported, the closing of the Rights Offering and the issuance of the shares of common stock to subscribing holders are contingent upon the consummation of its previously announced pending acquisition of the global recycling and specification alloys business of Aleris Corporation, to occur on or about February 27, 2015. The Company estimated that within the next few business days, the subscription agent for the Rights Offering will issue 7,899,215 shares in respect of all valid basic subscriptions and 1,852,558 shares in respect of the oversubscription requests that have been fulfilled. In addition, the subscription agent will distribute refund checks, as applicable, for unfulfilled oversubscription requests.  As a result of the Rights Offering, the Company’s outstanding common stock will increase by 9,751,773 shares.

A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated into this Item 8.01 by reference.

ThE Rights Offering is being made only by means of the prospectus supplement, dated January 29, 2015.
