Thales (ENXTPA:HO) has drawn fresh attention after working with HII on an end to end autonomous mine countermeasure system, integrating its modular Expeditionary Pathmaster architecture with HII’s REMUS 620 underwater vehicle.
For context, Thales shares trade at €221.70 after a 1 day share price return that declined 1.29%, and short term momentum has softened with a 7 day share price return down 5.94%. The 3 year total shareholder return of 69.27% and 5 year total shareholder return of 202.44% still point to strong longer term value creation, even as recent defence and AI related headlines, including the mine countermeasure success and the upcoming ISG AI Impact Summit appearance in Paris on 9 November 2026, have not prevented a 90 day share price return that declined 17.09% and a year to date share price return that declined 5.66%.

Most Popular Narrative: 24% Undervalued
Thales is framed as undervalued in the most widely followed thesis, with a fair value of €291.33 set against the recent €221.70 close. The narrative therefore leans on order momentum, margins and cash generation rather than short term share price weakness.
Thales’ capacity expansions in radars, missiles and ammunition, with multiple product lines targeted to reach about 4x to 5x prior output by 2026, position the company to convert strong defence demand and a 15% organic increase in group order intake into higher sales, better fixed cost absorption and potentially stronger net margins.
See why 108 investors see Thales as 24% undervalued.
Result: Fair Value of €291.33 (UNDERVALUED)
Still, the Thales story can crack if Cyber & Digital stumbles again or if pressure in Digital Identity & Security margins persists for longer.

Another View: Thales Through The P/E Lens
On price relative to earnings, Thales looks less generous. The stock trades on a 30.5x P/E, compared with a fair ratio of 26.8x, the European Aerospace & Defense average at 30.4x and a 27.8x peer mean. That richer multiple raises a practical question for investors: Is the DCF upside worth paying above these reference points?
