FORWARD-LOOKING INFORMATION Certain statements contained in this presentation are “forward-looking statements” within the meaning of the federal securities laws.

Forward-looking statements include statements about, among other things, future costs and prices of commodities, production volumes, industry trends, anticipated cost savings, anticipated benefits from new products, facilities, acquisitions or divestitures, projected results of operations, achievement of production efficiencies, capacity expansions, future prices and demand for our products and estimated cash flows and sufficiency of cash flows to fund operations, capital expenditures and debt service obligations, as well as statements regarding trade cases, tariffs and other governmental actions. Forward-looking statements involve known and unknown risks and uncertainties, which could cause actual results to differ materially from those contained in or implied by any forward-looking statement. Important factors that could cause actual results to differ materially from the forward-looking statements include, but are not limited to, the following: (1) our ability to successfully implement our business strategy; (2) the success of past and future acquisitions or divestitures; (3) the cyclical nature of the aluminum industry, material adverse changes in the aluminum industry or our end-uses, such as global and regional supply and demand conditions for aluminum and aluminum products, and changes in our customers’ industries; (4) increases in the cost, or limited availability, of raw materials and energy; (5) our ability to enter into effective metal, energy and other commodity derivatives or arrangements with customers to manage effectively our exposure to commodity price fluctuations and changes in the pricing of metals, especially London Metal Exchange-based aluminum prices; (6) our ability to generate sufficient cash flows to fund our operations and capital expenditure requirements and to meet our debt obligations; (7) competitor pricing activity, competition of aluminum with alternative materials and the general impact of competition in the industry end-uses we serve; (8) our ability to retain the services of certain members of our management; (9) the loss of order volumes from any of our largest customers; (10) our ability to retain customers, a substantial number of whom do not have long-term contractual arrangements with us; (11) risks of investing in and conducting operations on a global basis, including political, social, economic, currency and regulatory factors; (12) variability in general economic or political conditions on a global or regional basis; (13) current environmental liabilities and the cost of compliance with and liabilities under health and safety laws; (14) labor relations (i.e., disruptions, strikes or work stoppages) and labor costs; (15) our internal controls over financial reporting and our disclosure controls and procedures may not prevent all possible errors that could occur; (16) our levels of indebtedness and debt service obligations, including changes in our credit ratings, material increases in our cost of borrowing or the failure of financial institutions to fulfill their commitments to us under committed facilities; (17) our ability to access credit or capital markets; (18) the possibility that we may incur additional indebtedness in the future; (19) limitations on operating our business and incurring additional indebtedness as a result of covenant restrictions under our indebtedness, and our ability to pay amounts due under our outstanding indebtedness; and (20) risks related to the Merger, including the possibility that the Merger may not be consummated; and (21) other factors discussed in our filings with the Securities and Exchange Commission, including the sections entitled “Risk Factors” contained therein. Investors, potential investors and other readers are urged to consider these factors carefully in evaluating the forward-looking statements and are cautioned not to place undue reliance on such forward- looking statements. We undertake no obligation to publicly update or revise any forward-looking statements, whether in response to new information, futures events or otherwise, except as otherwise required by law. NON-GAAP INFORMATION The non-GAAP financial measures contained in this presentation (including, without limitation, EBITDA, Adjusted EBITDA, commercial margin, and variations thereof) are not measures of financial performance calculated in accordance with U.S. GAAP and should not be considered as alternatives to net income and loss attributable to Aleris Corporation or any other performance measure derived in accordance with GAAP or as alternatives to cash flows from operating activities as a measure of our liquidity. Non- GAAP measures have limitations as analytical tools and should be considered in addition to, not in isolation or as a substitute for, or as superior to, our measures of financial performance prepared in accordance with GAAP. Management believes that certain non-GAAP financial measures may provide investors with additional meaningful comparisons between current results and results in prior periods. Management uses non-GAAP financial measures as performance metrics and believes these measures provide additional information commonly used by the holders of our 2023 Junior Priority Senior Notes and parties to our Term Loan Facility and the ABL Facility with respect to the ongoing performance of our underlying business activities, as well as our ability to meet our future debt service, capital expenditure and working capital needs. We calculate our non-GAAP financial measures 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. See “Appendix.” INDUSTRY INFORMATION Information regarding market and industry statistics contained in this presentation is based on information from third party sources as well as estimates prepared by us using certain assumptions and our knowledge of these industries. Our estimates, in particular as they relate to our general expectations concerning the aluminum industry, involve risks and uncertainties and are subject to changes based on various factors, including those discussed under “Risk Factors” in our filings with the Securities and Exchange Commission. WEBSITE POSTING We use our investor website (investor.aleris.com) as a channel of distribution of Company information. The information we post through this channel may be deemed material. Accordingly, investors should monitor this channel, in addition to following our press releases, Securities and Exchange Commission ("SEC") filings, and public conference calls and webcasts. The content of our website is not, however, a part of this presentation. 2
