Boeing Paid $4.7 Billion to Buy Back a Business It Sold in 2005
Boeing (BA) acquired Spirit AeroSystems for $4.7B in stock, including assumed debt, valuing the deal at $8.3B. Spirit, sold in 2005 for $900M, supplies Boeing with airplane structures. Boeing also agreed to sell three businesses to Archer Aviation (ACHR) for a stake and tech-sharing rights. Boeing's Q2 revenue rose 8% to $24.6B, with improved cash flow but still reporting losses. The company has a $715B backlog but faces debt and production constraints.
