Trading statement in respect of the six months ended 31 December 2010

17 February 2011

In terms of paragraph 3.4(b) of the Listings Requirements of the JSE Limited a listed company is required to publish a trading statement as soon as it is satisfied that a reasonable degree of certainty exists that the financial results for the period to be reported on next will differ by at least 20% from those of the previous corresponding period.

ARM’s interim results for the six months to 31 December 2010 (in comparison to the corresponding six months to 31 December 2009) have been positively impacted by a significant improvement in commodity markets and US Dollar prices for commodities. ARM’s results have further benefited from continuing growth as the Company’s key growth projects ramp up production.

The results for the period were however negatively impacted by the strengthening of the Rand versus the US Dollar.

Accordingly, ARM announces that it expects headline earnings per share to increase for the six months ended 31 December 2010 to between 710 and 750 cents per share (1H F2010: 214 cents per share). Basic earnings per share are expected to be in line with headline earnings per share and therefore expected to be in the same range. (1H F2010: 213 cents per share).

The financial information on which this trading statement is based has not been reviewed or reported on by the external auditors of ARM.

The company’s full interim results will be released on Monday 28 February 2011.
