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 measures of operating results that are adjusted to exclude wafer shipments from Wuhan Xinxin Semiconductor Manufacturing Corporation ("Wuhan Xinxin"), which SMIC began gradually phasing out in 3Q13. This earnings release includes non-GAAP revenue, non-GAAP cost of sales and non-GAAP gross margin. It also includes first quarter 2014 guidance for non-GAAP operating expenses, which is adjusted to exclude the effect of foreign exchange, employee bonus accrual, funding of R&D contracts from the government and gain from the disposal of living quarters. 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.

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