Lockheed Martin has entered into a definitive agreement to acquire Sikorsky Aircraft, a world leader in military and commercial rotary-wing aircraft, for $9.0 billion. The price is effectively reduced to approximately $7.1 billion, after taking into account tax benefits resulting from the transaction.

“Sikorsky is a natural fit for Lockheed Martin and complements our broad portfolio of world-class aerospace and defense products and technologies,” said Marillyn Hewson, Lockheed Martin chairman, president and CEO. “I’m confident this acquisition will help us extend our core business into the growing areas of helicopter production and sustainment. Together, we’ll offer a strong portfolio of helicopter solutions to our global customers and accelerate the pace of innovation and new technology development.”
