Malcolm Unsworth has been appointed to succeed LeRoy Nosbaum as president and chief executive officer of Itron effective March 31, 2009.

Nosbaum will remain on the Board and serve as its executive chairman until December 31, 2009.

Unsworth joined Itron in July 2004 as senior vice president, hardware solutions, following the acquisition of Schlumberger Electricity Metering. In April 2007, he was named senior vice president and chief operating officer of Actaris and promoted to president and COO of the company in April 2008. In December 2008 he was elected to the Board. Prior to joining Itron, he spent 25 years with Schlumberger in a variety of management positions in the electric, gas, water and systems businesses.

“This management change occurs at a very good time for Itron,” said Jon Eliassen, lead director for the company. “With the acquisition of Actaris completed, AMI deployments beginning, and the company’s financial condition strong, Itron is ready to embark on the next growth phase. Malcolm has the right combination of industry experience and a deep understanding of Itron on a global scale to take us into the next decade. Having been responsible for Actaris since the acquisition, he has gained an understanding of exactly what needs to be done, where it needs to be done, and when it needs to be done in order to take full advantage of the opportunities that lie ahead.”

“I’m looking forward to leading this company” said Unsworth. “We are well positioned for growing the company, meeting our customers’ needs, and providing terrific growth opportunities for our employees around the world. We will continue to deliver value to our shareholders and our customers.”
