Antin-backed Wildstone, an owner of outdoor media infrastructure, completed the acquisition of Grupo Redext, a network of large-format advertising billboards around larger cities in Spain, from GMT Communications Partners, a private equity firm. Financial terms were not disclosed. "Spain represents an important strategic expansion opportunity for Wildstone. The Spanish out-of-home sector has shown exceptionally strong recovery following COVID and the market has the right dynamics for Wildstone’s continued rapid growth," Damian Cox, Wildstone Founder and CEO.
