BT's ordinary shares are listed on the London Stock Exchange with ticker "BT.A".
BT shares were also listed on the New York Stock Exchange in the form of American Depositary Shares (ADSs) up until 13 September 2019. BT subsequently terminated its American Depositary Receipt (ADR) programme on 23 September, and intends to file a Form 15F with the SEC to deregister its equity securities at the earliest possible date, following the minimum 12 month waiting period from the date of ADR termination, in order to reduce reporting costs and complexity.
