Analysts have rued a "missed opportunity" for identity verification specialist GB Group (GBG) and said another takeover bid "should not be ruled out".
Experts at Panmure Gordon have also said GBG's growth has "continued to disappoint" during the second half of its financial year but that things should pick up in the future.
The briefing note comes after takeover talks between the Chester company and a Chicago-based private equity firm ended in October last year.
