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, CFO for four years, will aid Boeing’s transition after steering finances through post-Covid woes, raising $24B and selling assets worth $10.6B.
