The most successful junior single-seater team of recent years on the European ladder announced this week that it will combine its programmes in Formula 2, Formula 3, the Formula Regional European Championship by Alpine and various Formula 4 championships with a move into the US open-wheel scene next year.
It will enter a two-car team using engines from Chevrolet and base itself from a new headquarters in Indiana.
Piers Phillips will head up the operation as IndyCar CEO, following spells at Schmidt Peterson Motorsports and Rahal Letterman Lanigan Racing.
Facing the media following the announcement, alongside Phillips and IndyCar president Jay Frye, Rosin revealed that discussions over expanding into IndyCar had been ongoing for over two years.
Rosin acknowledges that its rookie season "will be a learning year" as it adapts to the unique combination of circuits on the IndyCar calendar that spans ovals as well as road and street courses, but feels the timing is right for Prema to "to expand our boundaries" following its move into sportscars in partnership with Iron Lynx to run the works Lamborghini SC63 programme in the World Endurance Championship.
Rosin said: "Why in '25? Of course, when Prema join a championship, it's not to join to be just a number or to be somebody part of it.
