Answer
If you hold a stock that is taking part in mandatory corporate actions such as a share consolidation, share split, spin off, takeover, merger, ISIN change, or exchange swap, this will be booked in automatically on your account.
If you hold a stock which is taking part in an optional corporate action such as a Tender Offer or Rights Issuance, once the action is announced you will receive notification from DEGIRO instructing how to take part. If you wish to take part and do not receive a notification from DEGIRO, please contact our service desk by e-mail.
