warrant dividend financial

"in connection with the warrant dividend distributed by DeFi Development Corp."

A warrant dividend is a payment to shareholders made in the form of warrants—receipts that give the holder the right to buy company shares at a set price in the future—instead of cash. It matters because it can boost potential upside like a coupon that lets you buy more stock later, but it can also dilute existing ownership and affect share value when the warrants are exercised, so investors should weigh future opportunity against possible dilution.
