** Shares in France's Exosens EXENS.PA rise about 4.6%, extending gains from Thursday when it closed about 8% higher
** The gains are fuelled by Berlin's backing U.S. demand to hike NATO spending target to 5%, say Oddo BHF analyst Aurelien Sivignon and Bernstein analyst Aleksander Peterc
** Germany is the number one customer for Exosens and investors are anticipating that Berlin will extend security contracts beyond 2027, Sivignon adds
** Exosens, a night vision systems maker, benefits from its role as key NATO supplier, with major contract wins in Germany, it said in April
** At Thursday's close, the mean 12-month forward P/E ratio for Exosens was 21.76 euros, 60.07% higher than at the end of 2024
** The shares are on top of France's large and mid-cap index SBF 120 .SBF120
