Additionally, as part of the closing, Tessera is to receive an exclusive, perpetual, worldwide license for MEA’s technology and know-how.

"Drone threats are now a reality at every site we protect, and effective defense begins with rigorous testing," said Michael Oster, CEO of Tessera. "MEA adds a critical testing capability to Tessera's AI-driven security platform, which connects predictive intelligence, sensing, analysis, decisioning and response. Over the long term, what we learn from MEA's testing will strengthen many of those layers. The transaction structure provides a path to full ownership as MEA scales." Following the transaction, MEA will remain majority owned by Motomova, and its management will remain unchanged. About Tessera Defense and Homeland Security Inc.
