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 DEGIRO will inform you on a best effort basis with instructions on 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.
