FOR IMMEDIATE RELEASE

MISCOR Group Removes HK Engine Components As Held-For-Sale

MASSILLON, OHIO, December 19, 2011 – MISCOR Group, Ltd. (MIGL)(“the Company”), a provider of outsourced maintenance and electro-mechanical repair and complementary services for a diverse range of industries, has announced that it’s Board of Directors has voted to change its classification of HK Engine Components, LLC (“HKEC”) from held-for-sale to held-and-used. Accordingly, for the year ended December 31, 2011, the operating results of HKEC will be classified in the continuing operations of the Company.

In 2009, the Company implemented a profit improvement and restructuring plan that included reclassifying HKEC as held-for-sale. During 2010 and for the first three quarters of 2011, HKEC was recorded as held-for-sale. Due to the favorable results from our ongoing profit improvement plan and restructuring activities, management assessed the classification of HKEC and found it to be in the Company’s best interest to forego selling HKEC at this time and reclassify the operations of HKEC into continuing operations. As a result of this assessment, assets with a carrying value of $3,015,000 for HKEC will be reclassified from assets held–for-sale to held-and-used (included in assets held-for-sale on the October 2, 2010 Condensed Consolidated Balance Sheets). As a result of this conversion, the Company will incur a one-time charge of approximately $364,000 during the 4^th quarter 2011. This one-time charge is to catch up for depreciation appropriately not recorded while HKEC was classified as held for sale.

“We do see significant value in HKEC and believe we would not have obtained the appropriate value for this business had we sold it today with the current market conditions,” remarked Michael P. Moore, President and CEO of MISCOR Group. “We continue to look forward to extending our relationship with the customers of HKEC, and management and staff of HKEC.”
