My old company, Sepura, continues to "hold its own" with shares holding their ground. Although they have fallen back from their peak of over 150p a share earlier this year, they are hovering around the 140-142p a share currently, which is just above the price at which they were floated about 12 years ago.
With both TETRA and DMR products they have a good future with a world-wide market.
UPDATE 1605z: Shares in Sepura ended the day at 140.5p.
UPDATE 3.9.14 2245z: Shares ended at 141.0p.
