SIGNATURE GROUP HOLDINGS REPORTS FIRST QUARTER 2015 RESULTS

SHERMAN OAKS, Calif., May 12, 2015 -- Signature Group Holdings, Inc. (NASDAQ: RELY) (“Signature” or the “Company”) today reported financial results for its first quarter ended March 31, 2015.

Management Commentary

Craig Bouchard, Signature’s Chairman and CEO, stated, “The 2015 first quarter results reflect the acquisition of Aleris Corporation’s global recycling and specifications alloy business (now named “Real Alloy”), multiple securities offerings, and the sale of North American Breaker Co., LLC (“NABCO”). In doing so, the Company was transformed from a modest but well-performing operating business into a leader in a critical, growing industry. We are pleased with the ongoing transition effort and have begun to implement Six Sigma Lean initiatives at Real Alloy.

“During the quarter we proposed two new directors for our Board. Patrick Deconinck and William Hall will be fantastic additions. Patrick will chair a newly formed Operations and Lean/Six Sigma Committee of the Board. His career at 3M makes him the perfect candidate for this responsibility. Bill’s experience is full of exceptional operational and industrial accomplishments, and he will participate on this committee as well.

“The 2015 first quarter results include only one month of performance from Real Alloy, and there are a number of one-time impacts resulting from the various transactions that took place during the period. At Signature, we believe in open and transparent communication with our stockholders, and beginning with the 2015 second quarter, we expect to host a quarterly earnings conference call with investors on an ongoing basis.

“Last month we uplisted our common shares to the Nasdaq Global Select Market. This should lead to increased and improved liquidity in our stock, an expanded shareholder base, and ultimately increased shareholder value.”

Real Alloy Acquisition

During the quarter the Company completed its $525 million Real Alloy acquisition after raising $475.8 million in debt and equity, including the issuance of $305 million in senior secured notes by its indirect wholly owned subsidiary, and capped off by a successful $55 million stapled rights offering that was oversubscribed by $42 million.

The Company has begun reporting the financial results of Real Alloy beginning as of the closing date of February 27, 2015. As such, Signature’s 2015 first quarter results include only thirty-three days of Real Alloy results of operations, representing only a fraction of a typical quarter of performance. The second quarter ending June 30, 2015, will be Real Alloy’s first complete quarter as a Signature operation.

The Company continues to make progress on transitioning Real Alloy into Signature, which includes 25 major transition projects involved in its initial Six Sigma program and more than 25 minor projects. John Miller, the Company’s Executive Vice President of Operations who is a master black belt Six Sigma specialist and possesses advanced technical skills developed during his 28-year tenure at 3M, is managing this transition project and will also take on this role for future acquisitions.

First Quarter 2015 Financial Highlights

Signature posted net earnings of $6.8 million in the first quarter of 2015, compared to $0.1 million in the same period in 2014. Total operating revenues were $137.8 million in 2015, compared to $0.1 million in the same prior in 2014. The Company’s earnings were driven by the one month of performance by the Company’s two operating segments Real Alloy North America and Real Alloy Europe, a $7.4 million income tax benefit in continuing operations, as well as a one-time gain of $38.9 million related to the sale of NABCO. These positive results were offset by a number of one-time expenses related to the transactions that took place during the period, including $14.4 million in expenses associated with the Real Alloy acquisition, $4.9 million in incremental interest expense associated with the private placement of Senior Secured Notes, which funded 50 days prior to the closing of the acquisition, and $3.7 million of noncash charges related to the fair value adjustment of acquired inventory as estimated under purchase accounting.

Balance Sheet

At March 31, 2015, Signature’s cash and cash equivalents were $28.6 million, total debt was $324.5 million, and stockholders’ equity was $145.9 million.  

Outlook for 2015

Mr. Bouchard concluded, “The Real Alloy transition is our top priority. Our goals include: reducing leverage, reducing COGS by 1% in 2015, completing the transition effort on time and ahead of budgeted expense, and organic growth of the business. As this work successfully rolls out, we will begin to look at incremental growth to our platform through additional accretive acquisitions.”

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

A non-GAAP financial measure is a numerical measure of historical or future financial performance, financial position or cash flows that excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance with GAAP in the balance sheets, statements of operations, or statements of cash flows; or includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the most directly comparable measures so calculated and presented. We report our financial results in accordance with GAAP; however, our management believes that certain non-GAAP performance measures, which we use in managing our businesses, may provide investors with additional meaningful comparisons between current results and results in prior periods. Adjusted EBITDA is an example of a non-GAAP financial measure that we believe provides investors and other users of our financial information with useful information.

Management uses Adjusted EBITDA as a performance metric and believes this measure provides additional information commonly used by holders of our common stock, as well as the holders of the Senior Secured Notes and parties to the Asset-Based Facility with respect to the ongoing performance of our underlying business activities, as well as our ability to meet our future debt service, capital expenditures and working capital needs. In addition, Adjusted EBITDA is a component of certain covenants under the Indenture governing the Senior Secured Notes.

Our Adjusted EBITDA calculations represent net earnings before interest, taxes, depreciation and amortization, unrealized gains and losses on derivative financial instruments, share-based compensation expense, charges and expenses related to acquisitions, and certain other gains and losses.

Adjusted EBITDA as we use it may not be comparable to similarly titled measures used by other companies. We calculate Adjusted EBITDA by eliminating the impact of a number of items we do not consider indicative of our ongoing operating performance and certain other items. You are encouraged to evaluate each adjustment and the reasons we consider it appropriate for supplemental analysis. However, Adjusted EBITDA is not a financial measurement calculated and presented in accordance with GAAP, and when analyzing our operating performance, investors should use Adjusted EBITDA in addition to, and not as an alternative for, net earnings, operating income or any other performance measure derived in accordance with GAAP, or in addition to, and not as an alternative for, cash flows from operating activities as a measure of our liquidity. Adjusted EBITDA has limitations as an analytical tool, and it should not be considered in isolation, or as a substitute for, or superior to, our measures of financial performance prepared in accordance with GAAP. These limitations include:

In addition, in evaluating Adjusted EBITDA it should be noted that in the future we may incur expenses similar to the adjustments in the below presentation. Our presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by unusual or nonrecurring items.

The table below provides a reconciliation of Adjusted EBITDA to its most directly comparable financial measure presented in accordance with GAAP. Our reconciliation of Adjusted EBITDA to net earnings for the three months ended March 31, 2015 follows:
