First of all, you need to contact your brokerage company. Most brokers can arrange for your depositary receipts (DRs) to be converted into shares.

Procedures for converting the depositary receipts into PJSC Gazprom’s shares:

• Standard conversion. If the DRs were not converted automatically and the investor did not use the declarative conversion procedure, then the standard conversion procedure can be used up to August 3, 2023;
• Declarative conversion. This option was available for holders or beneficial owners of the DRs the rights to which were recorded in foreign depositories. The declarative conversion was completed on November 24, 2022, but you can still use the standard conversion procedure;
• Automatic conversion was performed only with regard to the DRs which are in the custody of Russian depositories (those are mostly the DRs that were purchased at SPB Exchange). The shares were credited to the accounts of investors in the same depositories where the respective DRs were placed
