“We are impressed and gratified by the vitality of Hanover's employees, the strength of its customer relationships, and the resilience of its outsourced compression markets,” he said. “I am very impressed with the caliber and quality of Hanover's field operations and equipment fabrication capabilities.”

The board is working with the executive search firm of Korn Ferry International to select a permanent chief executive officer.

The Company has scheduled a conference call to discuss these matters and its second quarter financial results on Monday, August 5, at 1:00 p.m. ET.

“Victor Grijalva is a highly experienced energy services executive with a reputation for sound business judgment and decisiveness, and with an extraordinary amount of experience in developing and leading winning management teams,” said Michael O'Connor, chairman emeritus. “We are fortunate to have his clear-eyed leadership and global perspective as Hanover Compressor makes the transition to its next stage of growth. Since joining the board, Victor has injected a renewed sense of enthusiasm and confidence in the continued growth potential of the Company.”
