23 東亞銀行，１０股送１服一問

Sorry that I haven't buy / sell stock for 1.5yr ...  I have no account to check the last day for registration.  You could contact your broker / bank for the last day of registration, usually 2-3 weeks after the result announcement.  In short, you could still have the additional stock if you purchase tomorrow.  But frankly, it is not a good time to buy bank / financial sector share before Q2 this year.
