FOR IMMEDIATE RELEASE

MISCOR Group Reports New Financing Arrangement with PNC Bank, N.A.

MASSILLON, OHIO, Dec. 26, 2012 – MISCOR Group, Ltd. (OTCQB: MIGL), a provider of outsourced maintenance and electro-mechanical repair and complementary services for a diverse range of industries, reported today that it has entered into a new credit facility with PNC Bank, National Association (“PNC”), replacing its secured credit agreement with Wells Fargo Bank, N.A. The new PNC credit facility includes a revolving line of credit and term loan that will be used for working capital, capital expenditures, refinancing of existing debt and general corporate purposes.

“We are pleased to begin this relationship with PNC,” stated Michael P. Moore, President and CEO of MISCOR Group. “Their desire and willingness to step forward with a comprehensive package speaks to their confidence in MISCOR’s business strategy and their commitment to partner with MISCOR in expanding our capabilities to better serve our customers.”

The terms of the new credit facility allow for a two-year $6.5 million secured revolving line of credit with an initial interest rate of LIBOR plus 2.75%. The terms of the new credit facility also provide a five-year $2.5 million secured term loan with an initial interest rate of LIBOR plus 3.00%. In both instances, based on achieving targeted funded debt to EBITDA, the Company can reduce the interest rates to as low as LIBOR plus 1.25% and LIBOR plus 1.50%, respectively.

“The new agreement with PNC provides MISCOR Group with the ability to pay off higher priced subordinated debt, thus consolidating all of MISCOR’s financing with one lender,” said Marc Valentin, Chief Accounting Officer of MISCOR Group. “It provides more flexibility at a significantly lower cost. Additionally, we will be moving all of our cash management activities to PNC. We look forward to working with PNC and their local team.”

“I am extremely proud of our team,” said Moore. “We have come through a very difficult economic period, and are seeing the fruits of our labor. We have greatly improved profitability, margins, cash flow and overall financial stability. Our success in executing on the strategic growth initiatives put in place in 2011 has made this new agreement with PNC possible. We are excited about the opportunities the agreement provides to add strategic capital, improve our existing operations, and execute acquisitions in regions strategic to our key customers.”
