Private equity firms and an aerospace supplier are actively vying to purchase Boeing's Jeppesen navigation division for over $8 billion. Sources reveal that Boeing will soon start accepting bids from interested parties, with several private equity firms expressing interest in acquiring Jeppesen together. The potential buyers include Vista Equity and Warburg Pincus, Advent International and Permira, and TPG and Francisco Partners. Alongside private equity firms, aircraft parts manufacturer TransDigm, and technology-focused investment firms Thoma Bravo and Silver Lake are also submitting separate bids. While Honeywell and Carlyle have shown interest, it remains uncertain if they will proceed with final offers. If the sale of Jeppesen succeeds, it will mark a significant transaction in the industry. The valuation of Jeppesen is anticipated to range between $8 billion and $9 billion, exceeding Boeing's initial estimation due to strong demand from potential buyers. Boeing is poised to narrow down the list of potential purchasers before final bids are made. The sale of Jeppesen is part of Boeing's strategy to streamline its operations and lower its debt burden. In a parallel effort, Boeing is looking to sell its drone unit Insitu. Jeppesen, known for its navigation solutions, is considered an attractive asset that can enhance aerospace contractors and private equity firms seeking steady cash flow. TransDigm, with a market value of about $77 billion, has made substantial acquisitions in recent years, including DART Aerospace, Calspan, CPI's electron device business, and Raptor Scientific.
