Brampton, ON- MDA, a Maxar Technologies company (formerly MacDonald, Dettwiler and Associates Ltd.), (NYSE: MAXR; TSX: MAXR), announced today it has acquired Neptec Design Group Ltd. (Neptec), the leading electro-optical and electro-mechanical systems and high-performance intelligent Light Detection and Ranging (LIDAR) company for CA$42 million, comprised of approximately CA$8 million in cash and the balance in Maxar common shares. With Neptec, MDA will deliver end-to-end robotic systems and an expanded set of solutions, positioning the company to capture growth in U.S., Canadian and global space exploration markets and accelerate advancement into new and expanding space segments. The transaction is accretive to Maxar’s operating earnings per share beginning in 2019, solidifies MDA’s leadership in space robotics innovation, and reinforces Maxar’s industry-leading space capabilities.

Neptec’s approximately 100 employees in Ottawa, Canada, and Harwell, U.K., will join MDA’s workforce of approximately 1,900 across Canada. The new Sensor business will combine with the newly createdMDA Commercial divisionunder the MDA brand.

“Today’s announcement provides a tremendous opportunity to advance and grow MDA and Neptec internationally, develop powerful new technologies and drive future economies,” said Mike Greenley, group president of MDA. “The Neptec team is well-established in the industry, and this investment represents an important strategic opportunity to offer broader solutions for the growing space exploration market.”

“As a global leader in space technology,” Greenley continued, “I am excited to solidify our position as the provider of the most valuable space exploration products in the world by adding Neptec’s world-class sensor and vision systems and robust space robotic capabilities to our industry-leading space portfolio.”

MDA’s suite of space robotics and exploration capabilities combine with Neptec’s space sensors and exploration robotics to provide commercial and government customers worldwide with innovative, three-dimensional space systems that augment the functionality of robotic systems, including such tasks as capturing space vehicles and berthing them to structures. Neptec also operates LIDAR systems, which deliver reliable guidance and navigation sensors for space vehicles.

“In our nearly 30-year history, Neptec has contributed critical systems to some of the most demanding space exploration missions, and we’ve built a reputation for making things work in challenging environments,” said Paul Nephin, Neptec CEO. “Combining our capabilities with MDA creates a tremendous opportunity to win new business and continue to expand our footprint in Canada, the United Kingdom and globally.”

Neptec’s capabilities are aligned with growth areas fueling the new space economy including on-orbit servicing, space mining, space manufacturing and theLunar Orbital Platform-Gateway(Gateway), a planned lunar-orbit space station planned for the 2020’s. The next-generation of Canadarm will provide critical Gateway operations, including assembly of the Gateway itself and its ongoing maintenance, capture of visiting spacecraft and execution of scientific experiments and operations conducted in the lunar vicinity. Robotics needed for this project will incorporate significantly more autonomous decision-making capabilities using artificial intelligence and state-of-the-art robotics and software.

Fast, secure communications will also be critical for deep space missions. Neptec has been working to further quantum computing in the area of space communications, and has participated in a project that developed anAcquisition, Pointing and Tracking fine pointing systemfor future satellite payloads to solve the long-standing problem of securely transporting information between distant locations.
