Australia and then in Europe, siring well over 300 stakes winners. His sons include current Coolmore stallions Rock of Gibraltar, Dylan Thomas, Fastnet Rock and Holy Roman Emperor. Coolmore's current leading sire was Galileo, who as of 2022 has led the leading sire list twelve times, unfortunately on the 10 July 2021 Galileo had to be euthanised. With the victory of Minding in the 2016 1000 Guineas, Galileo has sired at least one winner in each of British Classic Races. Several of Galileo's sons are currently standing at Coolmore, including classic winners Australia and Gleneagles. 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. Branches The original farm is now known as Coolmore Ireland, and has three branches: Coolmore Australia, Ashford Stud, which operates as Coolmore America, and Coolmore National Hunt (or Castle Hyde Stud) in Ireland, which specialises in breeding for National Hunt racing. Coolmore has many "shuttle stallions" that cover mares in either Ireland or Kentucky in the northern breeding season and are transported to Australia and South America for the southern breeding season. Coolmore America (Ashford Stud) Ashford Stud, located near Versailles, Kentucky, became a part of Coolmore in the mid-1980s. In 2001, Thunder Gulch was the first Ashford sire to top the American general sire listing. Giant's Causeway later became the leading sire in 2009, 2010 and 2012. Ashford also stands Uncle Mo, leading first year sire of 2015 and sire of 2016 Kentucky Derby winner Nyquist. Whereas most stallions standing at Coolmore Ireland are now homebreds, most of those standing at Ashford Stud had their breeding rights purchased during their racing career. For example, in May 2015 it was announced that Ashford Stud had purchased the breeding rights to American Pharoah from Ahmed Zayat in late 2014 for a reported $13.8 million. American Pharoah went on to become the first racehorse in 37 years to win the American Triple Crown, and the first ever to win the Grand Slam of Thoroughbred racing by
