Boeing Co. said Chief Financial Officer Brian West, who helped orchestrate one of the biggest capital raises in US corporate history last year to steady the crisis-stricken planemaker, is stepping down.

Boeing said Brian West, its chief financial officer, would depart the role later this summer and be succeeded by the former financial chief of Lockheed Martin.

Brian West will step down as Boeing CFO from mid-August and will be replaced by former Lockheed Martin Corp. executive Jesus “Jay” Malave, Boeing said in a statement.
