Airbus supplier Velocity Composites came to power when founder and former boss Jon Bridges called for the board members to be readmitted.
Bridges was knocked down from his position as Chief Executive Officer to Chief Technical Officer in September following his third profit warning. He later left the board.
The 43-year-old, however, together with his co-founders Gerard Johnson and Christopher Banks, demands that he and his former director Peter Turner, who also resigned in August, return to the top brass group.
The founders wrote a letter to Chairman Mark Mills, who took over the responsibility of the chief executive until a replacement was found.
Standstill: Stocks of Airbus' Velocity Composites slumped 74.1 percent last year, wiping out the AIM-listed company by £ 29.5m
They demanded that a number of unspecified board members, who were believed to include Mills themselves, step down at 5:00 pm yesterday.
Mills does not intend to resign, but Bridges and its partners, who together own 43 percent of the company, have threatened to convene a general meeting if no one volunteers.
This would mean that the roles of the Board – and the reinstatement of Bridges and Turner – would be brought to shareholder vote.
Velocity described the planned conversion as "harmful" and not in the interest of all shareholders.
Mills and two other non-executive directors claimed they would resign if Bridges and Turner returned to the company.
Shares in Velocity, which also produce parts for Typhoon fighters, slumped 74.1 percent last year, wiping out the AIM listed company by £ 29.5 million.
