We own and operate Derby City Gaming, a historical racing machine ("HRM") facility in Louisville, Kentucky. We also own and operate the largest online horse racing wagering platform in the U.S., TwinSpires.com, and we operate sports betting and iGaming through our BetAmerica platform in multiple states.

Our internal management reporting changed primarily due to the continued growth in our Churchill Downs Racetrack and Derby City Gaming business and our casino and associated racing businesses, which resulted in our chief operating decision maker's decision to realign our operating segments primarily based on the regulatory licenses governing each business. Since each of these individual businesses operates under single or interdependent licenses, each of these businesses represents an operating segment. As our TwinSpires business and online sports betting and iGaming businesses are managed together, these businesses represent an operating segment. For financial reporting purposes, we aggregate our operating segments that are similar into three reportable segments as follows: </span></div><div style="text-indent:-18pt;padding-left:36pt;margin-top:9pt;margin-bottom:3pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">•</span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%;padding-left:14.5pt;">Churchill Downs</span></div><div style="padding-left:36pt;text-align:justify;margin-top:3pt;margin-bottom:9pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">The Churchill Downs segment includes live and historical pari-mutuel racing related revenue and expenses at Churchill Downs Racetrack and Derby City Gaming. </span></div><div style="padding-left:36pt;text-align:justify;margin-top:9pt;margin-bottom:9pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">Churchill Downs Racetrack is the home of </span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%;">The Kentucky Derby </span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">and</span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%;"> </span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">conducts live racing during the year.
