In April 2015, Leighton changed its name to CIMIC Group (abbreviated from Construction, Infrastructure, Mining and Concessions).
In March 2022, CIMIC was accused of arranging its affairs through the sale of its Middle Eastern business interests to avoid paying workers, subcontractors and suppliers in the region. Fatima Almass Al-Hamad, a judicial guard in Qatar, who was appointed by the court as an administrator of the Qatar business, Leighton Contractors Qatar, described the situation as "a humanitarian disaster".
Major projects undertaken by Leighton Contractors (renamed CPB Contractors in January 2016) include:
