Sunrise announces date of termination of its sponsored Class B ADS program
Following the termination of the sponsored Sunrise Class A ADS program on 13 November 2025, Sunrise announces today that it has instructed J.P. Morgan Chase Bank, N.A (the Depositary Bank) to terminate its sponsored Class B ADS program. The termination of the sponsored Class B ADS program will take effect on 30 January 2026.
As of 12 December 2025, c. 99% of the Class B ADSs have been exchanged for Sunrise Class B Shares on a net basis with approximately 300,000 Class B ADSs outstanding.
Following the termination of the Class B ADS program, the Depositary Bank will exchange any Sunrise Class B Shares underlying outstanding Class B ADSs that continue to remain on deposit with the Depositary Bank into Sunrise Class A Shares ( at a ratio of 10 Sunrise Class B Shares for one Sunrise Class A Share) in accordance with Sunrise’s governing documents, sell the resulting Sunrise Class A Shares and disburse the resulting net proceeds (less fees owing to the Depository Bank), pro rata, to the applicable former Sunrise Class B ADS holders in accordance with, and subject to, the Class B Deposit Agreement. As previously announced, an amendment to the Class B ADS Deposit Agreement has become effective to permit the Depositary Bank (at termination effective time) to exchange any Sunrise Class B Shares underlying remaining Sunrise Class B ADSs for Sunrise Class A Shares prior to their sale.
Holders of Sunrise Class B ADSs will be notified by the Depositary Bank of the details relating to the termination of the Class B ADS program in accordance with the Class B Deposit Agreement, as amended. The Depositary Bank is expected to close the Class B ADS issuance book at the time it provides notification of the details relating to the termination of the Class B ADS program to the Class B ADS holders pursuant to the Class B Deposit Agreement and the Class B ADS cancellation books will be closed as of 5:00 pm EST on 30 January 2026 when the termination of the Class B ADS program becomes effective.
Class B ADS holders will not be able to cancel their Class B ADSs and withdraw the underlying Sunrise Class B Shares once the Class B ADS cancellation books are closed. Holders of Sunrise Class B ADSs that want to avoid having the underlying Sunrise Class B Shares exchanged for Sunrise Class A Shares and sold by the Depositary Bank following the termination of the Class B ADS program are advised to withdraw such Sunrise Class B Shares before the termination becomes effective at 5:00 pm EST on 30 January 2026.
