Zayat Stables, Susan Magnier, Michael Tabor and Derrick Smith

Ahmed Zayat was born in Cairo, Egypt to a wealthy family, and grew up in an ethnically-diverse neighborhood where he learned to ride horses. At age 18, he moved to the United States where he attended college and ultimately obtained a master's degree in business and public health from Boston University. After a brief career in commercial real estate in New York City, he returned to Egypt, and for about a decade ran the Al-Ahram Beverages Company, which he owned as part of an investment group. In horse racing, Zayat is most famous for campaigning 2015 Triple Crown and Breeders’ Cup Classic winner American Pharoah.

Englishman Derrick Smith, who lives in Barbados, is the part-owner of the Sandy Lane Hotel, a five-diamond luxury getaway in Barbados.

Susan Magnier, wife of Coolmore Stud owner John Magnier, is the daughter of famed Irish trainer Vincent O'Brien, one of the legends of the Turf who won 42 classic races in Europe during his career. Vincent O’Brien started Coolmore as a partnership in the 1970s with Tim Vigors and Robert Sangster. In the 1980s, John Magnier joined Coolmore and eventually became sole owner of one of the two leading international Thoroughbred owning-breeding enterprises, along with Godolphin.

Michael Tabor was the owner and chairman of the Prince Arthur betting shops in Great Britain. He sold the 114 shops on Sept. 29, 1995, to Coral, the country's third-largest operator of betting shops; the sale price was not disclosed, though estimates ranged from $15 million to $35 million. Tabor has been involved with Coolmore partners since the 1990s, and he enjoyed his first top-level success in U.S. racing in 1995 when Thunder Gulch won the Kentucky Derby and Belmont Stakes.
