GlaxoSmithKline PLC

22 December 2011

This announcement amends the original announcements released on 12 April 2011 at 18.00 (RNS No: 7966E); 12 July 2011 at 17.33 (RNS No: 2743K); and 11 October 2011 at 16.54 (RNS No: 9956P)

The Administrators of the GlaxoSmithKline Performance Share Plan (the "Plan") notified the Company and the under-mentioned persons on 21 December 2011 of an error in the market price of Ordinary shares which was used to calculate the notional number of shares received under the dividend reinvestment element of the Plan, in respect of dividends paid on 7 April 2011. The market price of Ordinary shares should have read 1216.50 pence rather than £12.22, and the participants' increased interests in Ordinary shares have been amended and the correct interests are set out below.

Given the cumulative nature of the dividend reinvestment, the correction in respect of the payment made on 7 April 2011 also had a minor impact on the calculation of the dividends reinvested for the affected Plan participants in respect of the dividend payments made on 7 July 2011 and 6 October 2011.

Amendments are identified with an asterisk (*).

Save as disclosed above, all other details remain unchanged. The full amended text is shown below.
