Publication of 2021 AGM Notice

GlaxoSmithKline plc

(the 'Company')

Publication of Notice of Annual General Meeting 2021

The Company has today published on its website (www.gsk.com/en-gb/investors/shareholder-information/annual-general-meeting/) the Notice of Annual General Meeting ('AGM') 2021 (the '2021 AGM Notice') which will be distributed to shareholders shortly.

The AGM will be broadcast live and all shareholders are invited to join electronically. UK Government COVID-19 restrictions mean that shareholders will unfortunately not be permitted to physically attend the AGM this year. 

The Company's AGM is to be held at 2.30pm on Wednesday, 5 May 2021 at the Company's registered office at 980 Great West Road, Brentford, Middlesex, TW8 9GS.

We are maximising the use of existing technology to offer shareholders a range of ways to participate in the AGM given that they cannot attend in person. Full details of how to join the meeting are being sent to shareholders directly and are contained in the 2021 AGM Notice and AGM Guide.

In compliance with Listing Rule 9.6.1R of the UK Financial Conduct Authority, the 2021 AGM Notice will be submitted to the UK Listing Authority and will, in due course, be available for inspection at https://data.fca.org.uk/#/nsm/nationalstoragemechanism.
