How big is it?
CoStar Group bought back $1.0B of stock in the twelve months to Jun 30, 2026. At that pace, $1.5B covers about 1.5 years of buybacks.
The amount equals 536% of its free cash flow over the same twelve months ($280M).
Its diluted share count is down 4.7% from a year earlier.
An authorization is permission, not a promise: the company can buy less, more slowly, or not at all, and usually doesn't have to say when it buys.
