Sensor developer FLIR Systems announced it has acquired unmanned aerial systems maker Prox Dynamics for $134 million in cash.

Based in Oslo, Norway and founded in 2007 by pioneers in nano helicopter technologies, Prox Dynamics develops, manufactures, and distributes aerial sensors that are revolutionarily small, light, and covert surveillance systems. Prox Dynamics’ Personal Reconnaissance System (PRS) features their Black Hornet aerial sensor and a hand controller, a system that is pocket sized and hand-launched by a soldier in the field, enabling a significant advantage in situational awareness and mission planning.

The Black Hornet aerial sensor utilizes FLIR’s Lepton micro thermal camera, visible spectrum cameras, advanced low-power rotor technology, and proprietary software for flight control, stabilization, and communications. The Black Hornet helicopter is one of the lightest, stealthiest, and safest drones in the market, offering a highly advanced, lifesaving surveillance solution for traditional military forces and special operations forces. Weighing less than one ounce, the Black Hornet helicopter can fly for up to 25 minutes at line-of-sight distances of up to one mile.

The addition of the Prox Dynamics business will augment FLIR’s Surveillance segment by extending FLIR’s Airborne sensor product line and fully leveraging Lepton technology. FLIR intends to invest in optimizing the PRS platform to further enhance the range, cost, flexibility, and performance of the system. The Prox Dynamics team will benefit from close interaction with FLIR’s thermal sensor development group as well as the ability to leverage FLIR’s brand, distribution, and customer support infrastructure to better serve a global base of users. The business will become FLIR’s Unmanned Aerial Systems (UAS) line of business operating within the Surveillance segment.

“This acquisition adds a unique unmanned aerial systems capability to our portfolio. The Prox Dynamics team has created a highly-differentiated solution, incorporating our Lepton sensor, for advanced intelligence, surveillance, and reconnaissance that fits well with our vision for growth for our Surveillance segment,” said Andy Teich, President and CEO of FLIR. “The team at Prox Dynamics operates with a commercial mindset, which is a great fit for FLIR’s ‘commercially developed, military qualified,’ or ‘CDMQ,’ operating philosophy. We are excited to welcome the Prox Dynamics team to FLIR and look forward to working together to further advance this remarkable system capability.”

FLIR anticipates the business and related transaction costs will be approximately $0.01 dilutive to its 2016 earnings per share.
