Summary of TMS INTERNATIONAL CORP.

Item 7.01 Regulation FD Disclosure.

On February 5, 2013, TMS International Corp. (the "Company") announced that certain of its subsidiaries, including Tube City IMS Corporation ("TCIMS") and Metal Services Holdco LLC, are pursuing a proposed repricing of TCIMS's outstanding senior secured Term Loan B (the "Term Loan") as well as requesting certain other changes to the applicable credit agreement. The proposed amendment and Term Loan refinancing are subject to lender consent and market and other conditions, and the Company makes no assurance that such actions will occur as described or at all.

In connection with the proposed repricing, the Company reaffirmed its previous 2012 Adjusted EBITDA guidance in a range of $142 million to $148 million, representing a year-over-year growth rate of 6% to 10%. As previously announced, the Company will report full year earnings on Feb. 14th.

Adjusted EBITDA is not a recognized financial measure under GAAP, but the Company believes it is useful in measuring its operating performance. Adjusted EBITDA is used internally to determine the Company's incentive compensation levels, including under its management bonus plan, and it is required, with some additional adjustments, in certain covenant compliance calculations under its senior secured credit facilities. The Company also uses Adjusted EBITDA to benchmark the performance of its business against expected results, to analyze year-over-year trends and to compare its operating performance to that of its competitors. The Company also use Adjusted EBITDA as a performance measure because it excludes the impact of tax provisions and Depreciation and Amortization, which are difficult to compare across periods due to the impact of accounting for business combinations and the impact of tax net operating losses on cash taxes paid. In addition, the Company uses Adjusted EBITDA as a performance measure of its operating segments in accordance with ASC Topic 280, Disclosures About Segments of an Enterprise and Related Information. The Company believes that the presentation of Adjusted EBITDA enhances its investors' overall understanding of the financial performance of and prospects for its business.
