Boeing (NYSE: BA) and Embraer (B3: EMBR3, NYSE: ERJ) announced they have signed a Memorandum of Understanding to establish a strategic partnership that positions both companies to accelerate growth in global aerospace markets.

The non-binding agreement proposes the formation of a joint venture comprising the commercial aircraft and services business of Embraer that would strategically align with Boeing’s commercial development, production, marketing and lifecycle services operations. Under the terms of the agreement, Boeing will hold an 80 percent ownership stake in the joint venture and Embraer will own the remaining 20 percent stake.

The transaction values 100 percent of Embraer’s commercial aircraft operations at $4.75 billion, and contemplates a value of $3.8 billion for Boeing’s 80 percent ownership stake in the joint venture. The proposed partnership is expected to be accretive to Boeing’s earnings per share beginning in 2020 and to generate estimated annual pre-tax cost synergies of approximately $150 million by year three.

The strategic partnership will bring together more than 150 years of combined leadership in aerospace and leverage the two companies’ highly complementary commercial product lines. The partnership is a natural evolution of a long-standing history of collaboration between Boeing and Embraer over more than 20 years.

On finalization, the commercial aviation joint venture will be led by Brazil-based management, including a President and Chief Executive Officer. Boeing will have operational and management control of the new company, which will report directly to Muilenburg.

The joint venture will become one of Boeing’s centers of excellence for end-to-end design, manufacturing, and support of commercial passenger aircraft, and will be fully integrated into Boeing’s broader production and supply chain.

Boeing and the joint venture would be positioned to offer a comprehensive, highly complementary commercial airplane portfolio that ranges from 70 seats to more than 450 seats and freighters, offering best-in-class products and services to better serve the global customer base.

In addition, both companies will create another joint venture to promote and develop new markets and applications for defense products and services, especially the KC-390 multi-mission aircraft, based on jointly-identified opportunities.
