Magnier, Mrs. John, Tabor, Michael B., Smith, Derrick, Westerberg, Rocket Ship Racing, LLC and Brant, Peter M.

The ownership group of Susan Magnier, Michael Tabor, Derrick Smith, Westerberg, Rocket Ship Racing, and Peter Brant enjoyed success in 2024 with standout 3-year-old Sierra Leone, winner of the Longines Breeders’ Cup Classic and Toyota Blue Grass Stakes and runner-up by a nose in the Kentucky Derby Presented by Woodford Reserve.

Magnier, Tabor, and Smith are part of the Ireland-based, internationally successful Coolmore group. Brook Smith is a Louisville businessman, insurance executive, and philanthropist who became a fan of horse racing when attending the Kentucky Derby in 1995. Peter Brant built a fortune in the paper mill industry and publishing, and made his foray into Thoroughbred racing in the 1970s, campaigning standouts including Just a Game, Waya, and Gulch. After a lengthy absence, Brant returned to the horse business in 2016 and quickly resumed winning marquee races with horses such as Sistercharlie.

Coolmore and Peter Brant purchased Sierra Leone for $2.3 million as a yearling at the Fasig-Tipton Saratoga select sale.
