Thales agreed on 6 July 2026 to buy Exail Technologies for €134 a share, an enterprise value of €3.9 billion ($4.5 billion), in a deal announced at its Meudon headquarters.1 Thales is France's largest defence-electronics group; Exail makes the autonomous underwater vehicles (AUV), uncrewed surface vessels (USV) and inertial navigation units that mine-hunting fleets increasingly run on.
The purchase folds those lines into a group whose TSAM towed synthetic-aperture sonar already sits aboard the Royal Navy's RNMB Ariadne and France's Sirius minehunting drone under the Anglo-French mine-countermeasures (MCM) programme. Thales was buying a supplier its own flagship programme already leaned on, a backward integration into vehicles and navigation it had been sourcing rather than a move into an unrelated line.
That vertical buy gives France a single national champion spanning sonar, autonomy and navigation, in the same undersea-hardware space where Kongsberg and DRASS pitched a European counter-bid for the hardware layer of the AUKUS pact (Australia, UK and US) in June. €134 a share also sets a public benchmark for undersea-autonomy valuations, the first nine-figure deal in a sector that until now traded in trials and memoranda; smaller European AUV specialists will be repriced against it before their next funding rounds.
