This presentation and any related statements contain certain “forward-looking statements” about MPG’s financial results and estimates and business prospects within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by words such as “expects,” “intends,” “anticipates,” “plans,” “project,” “believes,” “seeks,” “targets,” “forecast,” “estimates,” “will” or other words of similar meaning and include, but are not limited to, statements regarding the outlook for the Company’s future business, prospects, and financial performance; the industry outlook, our backlog and our 2015 financial guidance. Forward-looking statements are based on management’s current expectations and assumptions, which are subject to inherent uncertainties, risks, and changes in circumstances that are difficult to predict. Actual outcomes and results may differ materially due to global political, economic, business, competitive, market, regulatory, and other factors and risks, among them being: volatility in the global economy impacting demand for new vehicles and our products; a decline in vehicle production levels, particularly with respect to platforms for which we are a significant supplier, or the financial distress of any of our major customers; seasonality in the automotive industry; our significant competition; our dependence on large-volume customers for current and future sales; a reduction in outsourcing by our customers, the loss or discontinuation of material production or programs, or a failure to secure sufficient alternative programs; our failure to offset continuing pressure from our customers to reduce our prices; our inability to realize all of the sales expected from awarded business or fully recover pre-production costs; our failure to increase production capacity or over-expanding our production in times of overcapacity; our reliance on key machinery and tooling to manufacture components for powertrain and safety-critical systems that cannot be easily replicated; program launch difficulties; a disruption in our supply or delivery chain which causes one or more of our customers to halt production; work stoppages or production limitations at one or more of our customer’s facilities; a catastrophic loss of one of our key manufacturing facilities; failure to protect our know-how and intellectual property; the disruption or harm to our business as a result of any acquisitions or joint ventures we make; a significant increase in the prices of raw materials and commodities we use; the damage to or termination of our relationships with key third-party suppliers; our failure to maintain our cost structure; the incurrence of significant costs if we close any of our manufacturing facilities; potential significant costs at our facility in Sandusky, Ohio; the failure of or disruptions in our information technology networks and systems, or the inability to successfully implement upgrades to our enterprise resource planning systems; the incurrence of significant costs, liabilities, and obligations as a result of environmental requirements and other regulatory risks; extensive and growing governmental regulations; the adverse impact of climate change and related energy legislation and regulation; the incurrence of material costs related to legal proceedings; our inability to recruit and retain key personnel; any failure to maintain satisfactory labor relations; pension and other postretirement benefit obligations; risks related to our global operations; competitive threats posed by global operations and entering new markets; foreign exchange rate fluctuations; increased costs and obligations as a result of becoming a public company; the failure of our internal controls to meet the standards required by Sarbanes-Oxley; our substantial indebtedness; our inability, or the inability of our customers or our suppliers, to obtain and maintain sufficient debt financing, including working capital lines; our exposure to a number of different tax uncertainties; the mix of profits and losses in various jurisdictions adversely affecting our tax rate; disruption from the combination of our operations and diversion of management’s attention; our limited history of working as a single company and the inability to integrate HHI, Metaldyne, and Grede successfully and achieve the anticipated benefits. For the reasons described above, we caution you against relying on any forward-looking statements, which should also be read in conjunction with the other cautionary statements that are included elsewhere in this press release and in our public filings, including under the heading “Risk Factors” in our filings that we make from time to time w ith the Securities and Exchange Commission. You should not consider any list of such factors to be an exhaustive statement of all of the risks, uncertainties, or potentially inaccurate assumptions that could cause our current expectations or beliefs to change. Further, any forward-looking statement speaks only as of the date on which it is made, and we undertake no obligation to update or revise any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events, except as otherwise may be required by law.

Non-GAAP Financial Measures

Combined Net Sales We define Combined Net Sales as the net sales of MPG plus the net sales of Grede prior to our acquisition of Grede. We present Combined Net Sales because our management considers it to be a useful, supplemental indicator of our performance when comparing periods before and after our acquisition of Grede. For a reconciliation of Combined Net Sales to net sales, the most directly comparable GAAP measure, see Appendix to this presentation.

Adjusted EBITDA and Combined Adjusted EBITDA We define Adjusted EBITDA as net income (loss) before interest expense, provision for (benefit from) income taxes and depreciation and amortization, with further adjustments to reflect the additions and eliminations of certain income statement items, including (i) gains and losses on foreign currency and fixed assets and debt transaction expenses, (ii) stock-based compensation and other non-cash charges, (iii) sponsor management fees and other income and expense items that we consider to be not indicative of our ongoing operations, (iv) specified non-recurring items and (v) other adjustments. We define Combined Adjusted EBITDA as Adjusted EBITDA plus the Adjusted EBITDA of Grede prior to our acquisition of Grede. We believe Adjusted EBITDA is used by investors as a supplemental measure to evaluate the overall operating performance of companies in our industry. Management uses Adjusted EBITDA (i) as a measurement used in comparing our operating performance on a consistent basis, (ii) to calculate incentive compensation for our employees, (iii) for planning purposes, including the preparation of our internal annual operating budget, (iv) to evaluate the performance and effectiveness of our operational strategies and (v) to assess compliance with various metrics associated with our agreements governing our indebtedness. Accordingly, we believe that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating performance in the same manner as our management. We present Combined Adjusted EBITDA because our management considers it to be a useful, supplemental indicator of our performance when comparing periods before and after our acquisition of Grede. For a reconciliation of Adjusted EBITDA and Combined Adjusted EBITDA to net income, the most directly comparable measure determined under U.S. generally accepted accounting principles (“GAAP”), see Appendix to this presentation.

Adjusted Free Cash Flow and Combined Adjusted Free Cash Flow We define Adjusted Free Cash Flow as Adjusted EBITDA less capital expenditures. Capital expenditures can be found in our consolidated statements of cash flows as a component of cash flows from investing activities. We define Combined Adjusted Free Cash Flow as Adjusted Free Cash Flow plus the Adjusted Free Cash Flow of Grede prior to our acquisition of Grede. We present Adjusted Free Cash Flow because our management considers it to be a useful, supplemental indicator of our performance. When measured over time, Adjusted Free Cash Flow provides supplemental information to investors concerning our results of operations and our ability to generate cash flows to satisfy mandatory debt service requirements and make other non-discretionary expenditures. We present Combined Adjusted Free Cash Flow because our management considers it to be a useful, supplemental indicator of our performance when comparing periods before and after our acquisition of Grede. For a reconciliation of Adjusted Free Cash Flow and Combined Adjusted Free Cash Flow to net income, the most directly comparable GAAP measure, see Appendix to this presentation.

Combined Non-GAAP CapEx We define Combined CapEx as the capital expenditures of MPG (“CapEx”) plus the capital expenditures of Grede prior to our acquisition of Grede. We present Combined CapEx because our management considers it to be a useful, supplemental indicator of our performance when comparing periods before and after our acquisition of Grede. For a reconciliation of Combined CapEx to CapEx, the most directly comparable GAAP measure, see “GAAP RECONCILIATION”.
