(NASDAQ:PTEN) ("Patterson-UTI" or "the Company") today announced a multi-year agreement to lease two high-spec APEX 1500^® drilling rigs to DLS Archer Ltd. S.A ("Archer"), a division of Archer Ltd. The rigs will support Archer's operations in Argentina's Vaca Muerta formation as part of its seven-rig contract with YPF S.A. ("YPF") that was announced in December 2025.
