This company is 52.8 years old and is currently active. It is controlled by Rolls-Royce Group Limited. The company has negative equity (net assets) of GBP -1.1 billion which has worsened since the previous year's figure of GBP 879 million. The latest reported revenue figure is GBP 16.6 billion which is up 10% on previous year's figure of GBP 15.7 billion. The company is both loss making and has negative equity, it is therefore likely to go bankrupt unless it can raise funding or business has improved since the last accounts were filed. Retained earnings is negative (GBP -3.1 billion), which means the company has aggregate losses since it's inception or it has paid more dividends than it can afford; given the company's age, this is a sign of serious financial problems. The company has 4 active officers (directors or partners) who are or were officers of 5 other companies. The company has no public disputes filed on the Business Disputes Register. There are 17 court cases involving the company that we are aware of.
