B. Riley & Co. 16th Annual Investor Conference PRESENTATION May 13, 2015 Exhibit 99.1

Cautions about Forward-Looking Statements and Other Notices Legal Notices. Signature Group Holdings, Inc. (the “Company”) has filed a registration statement (including a prospectus and two prospectus supplements) with the Securities and Exchange Commission (“SEC”) for the rights offering to which this communication relates. Before you invest, you should read the prospectus supplements and the base prospectus (collectively, the “prospectus”) included in the Company’s registration statement and other documents we have filed with the SEC for more complete information about us and this offering. The prospectus and the registration statement may be accessed through the SEC’s website at www.sec.gov. Alternatively, we will arrange to send you the prospectus if you request it from: 15301 Ventura Boulevard, Suite 400, Sherman Oaks, California 91403, (805) 435-1255. This prospectus is not an offer to sell and we are not soliciting an offer to buy in any state or other jurisdiction in which the offer or sale is not permitted. THE COMMISSIONER OF BUSINESS OVERSIGHT OF THE STATE OF CALIFORNIA DOES NOT RECOMMEND OR ENDORSE THE PURCHASE OF THESE SECURITIES. Use of Non-GAAP Measures. This presentation includes references to the non-GAAP financial measures of earnings before interest, taxes, depreciation and amortization (“EBITDA”) and, with certain additional adjustments (“Adjusted EBITDA”). Management believes that the non-GAAP measures of EBITDA and Adjusted EBITDA enhance the understanding of the financial performance of Real Alloy’s (the former global recycling and separation alloys business of Aleris Corporation) operations by investors and lenders. As a complement to financial measures recognized under GAAP, management believes that EBITDA and Adjusted EBITDA assist investors who follow the practice of some investment analysts who adjust GAAP financial measures to exclude items that may obscure underlying performance and distort comparability. Because EBITDA and Adjusted EBITDA are not measures recognized under GAAP, they are not intended to be presented herein as a substitute for earnings (loss) from continuing operations, net earnings (loss), net income attributable to Aleris or Real Alloy, or segment income, as indicators of operating performance. EBITDA and Adjusted EBITDA are primarily performance measurements used by our senior management and Board of Directors to evaluate certain operating results. Reconciliation to the GAAP equivalent of the non-GAAP measure of EBITDA and Adjusted EBITDA for Real Alloy is provided in Note 4 on page S-35 of the Prospectus Supplement No. 1 dated January 29, 2015 for the rights offering to which this communication relates as filed with the SEC. Cautionary Statement Regarding Forward-Looking Statements. This presentation contains forward-looking statements, which are based on our current expectations, estimates and projections about the Company’s and its subsidiaries’ businesses and prospects, as well as management’s beliefs and certain assumptions made by management. Words such as “anticipates,” “expects,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “may,” “should,” “will” and variations of these words are intended to identify forward-looking statements. Such statements speak only as of the date hereof and are subject to change. The Company undertakes no obligation to revise or update publicly any forward-looking statements for any reason.

Such statements are not guarantees of future performance and are subject to certain risks, uncertainties, and assumptions that are difficult to predict.
