Although the stallion operation receives the most attention, Coolmore also maintains a large broodmare band and boards mares for clients. Coolmore is active at major breeding stock sales, looking for mares that are best suited to its stallions. For example, in 2012 Coolmore paid $5 million for Untouched Talent, already the dam of grade 1 winner
Bodemeister, with plans to breed her to Galileo. In 2016, Coolmore announced that Untouched Talent was the first mare confirmed in foal to American Pharoah.

National Hunt
Coolmore's National Hunt division consists of three farms in Ireland: Grange Stud, Beeches Stud and Castlehyde Stud. The Magnier family has been breeding horses for the
National Hunt since the 1850s. Over the generations, they have stood several outstanding jump stallions, including 14-time leading sire Deep Run, and 4-time leader Be My Native. Although Sadler's Wells was never a National Hunt sire per se, several champion hurdlers trace back to him.
Yeats, a son of Sadler's Wells renowned for his staying ability, now stands at Castlehyde Stud, in the 2021-22 jumps season Yeats became Champion Sire for the first time.
