About Non-Generally Accepted Accounting Principles ("non-GAAP") Financial Measures

To supplement SMIC's consolidated financial results presented in accordance with IFRS, SMIC uses in this press release non-GAAP measures of operating results that are adjusted to exclude finance cost, depreciation and amortization, income tax benefits and expenses, the effect of employee bonus accrual, government funding, gain or loss on the disposal of machinery and equipment and gain from the disposal of living quarters. This earnings release also includes second quarter 2018 guidance for non-GAAP operating expenses. The presentation of non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with IFRS. This earnings release includes EBITDA, EBITDA margin and non-GAAP operating expenses which consist of total operating expenses as adjusted to exclude the effect of employee bonus accrual, government funding, gain or loss on the disposal of machinery and equipment and gain from the disposal of living quarters. These non-GAAP financial measures are not calculated or presented in accordance with, and are not alternatives or substitutes for financial measures prepared in accordance with IFRS, and should be read only in conjunction with the Group's financial measures prepared in accordance with IFRS. The Group's non-GAAP financial measures may be different from similarly-titled non-GAAP financial measures used by other companies.

SMIC believes that use of these non-GAAP financial measures facilitates investors' and management's comparisons to SMIC's historical performance. The Group's management regularly uses these non-GAAP financial measures to understand, manage and evaluate the Group's business and make financial and operational decisions.

The accompanying table has more information and reconciliations of each non-GAAP financial measure to its most directly comparable GAAP financial measure. A reconciliation of non-GAAP guidance measures to corresponding GAAP measures is not available on a forward-looking basis because the effect of these adjustment items excluded for the purpose of non-GAAP operating expenses guidance are subject to some unpredictable conditions that cannot be estimated with reasonable certainty.

SMIC has filed with the U.S. Securities and Exchange Commission its annual report on Form 20-F for the year ended December 31, 2017. The annual report is available on our website at www.smics.com. In addition, all SMIC ADR holders have the ability, upon request, to receive a hard copy of our complete audited financials free of charge.
