One thing for certain is if you are currently a Sky shareholder you will not need a Medallion Guarantee in order to sell or transfer shares, however this may soon change. We read last month that Comcast have now made a higher bid that then one previously offered by 21st Century Fox for Sky. If acceptable to all concerned Comcast will become a majority shareholder in Sky and the company will then become a US Company. This would probably mean that when you need to sell shares the company, it will mean you are selling shares in a US company which means you will need a Medallion Signature Guarantee in order to deal with the shares. This is because whoever is the share registrar, known as the Transfer Agent in the US, they will require the medallion stamp in order to confirm the identity of the shareholder before they authorise the transfer.
