1950–1990
By the 1950s, the Inchcape family had diverse interests around the world. This period brought new legislation and tax laws and, under The 3rd Earl of Inchcape, the family's many interests, including MMC, were consolidated into Inchcape and Company.[5][8] In August 1958, Inchcape and Company became a public company and offered twenty five per cent of its equity for sale on the London Stock Exchange.[5][3]
Throughout this period, Inchcape's growth came largely as a result of a series of mergers and acquisitions.[9] During 1967, it merged with Borneo Company Limited, which almost doubled the company's size via the addition of operations in Hong Kong, Malaysia, Canada, Singapore, Brunei and Thailand to the operation.[5] In 1971, Millars of Western Australia was purchased for $5 million.[10]
In 1972, Dodwell & Company was acquired, which added extensive shipping, motors and business-machine trading across the Far East;[5] it was during this era that Inchcape pivoted away from its traditional focus on India toward opportunities across the Far East.[11] Dodwell & Company gave Inchcape further interests in this region, which it maintained as quasi-independent companies, rather than forming one large entity. Dodwell & Company was founded in Shanghai in 1858, and by the 1970s had established extensive businesses in shipping, motors and business-machine trading in Hong Kong, Japan and many other Far Eastern ports and cities.[5]
Mann Egerton, acquired in 1973, laid the foundations for Inchcape's motor-distribution business. Founded at the end of the 19th century in Norwich by an electrical engineer and an early motoring pioneer, Mann Egerton sold cars manufactured by De Dion-Bouton, Renault and Daimler at the turn of the century, initially from branches in the eastern counties of England. By the 1970s, Mann Egerton distributed British Leyland cars, as well as an extensive range of luxury cars.[5] Inchcape bought Joska Bourgeois's Japanese car distribution business, the International Motor Company, for £14.6 million in 1979.[12]
Reincorporated as Inchcape plc in 1981, the company acquired several petrol, textile, electronic and mineral testing and inspection companies during the 1980s and formed a specific testing business division. The testing division continued to grow into the 1990s via the acquisition of the Caleb Brett group, SEMKO and various others entities, such as ETL Testing Laboratories.[13][14]
By 1989, the motors division of Inchcape was contributing two-thirds of group turnover and 53.6 percent of group profits, the greater part contributed by Toyota.[5] Between 1980 and 1989, Inchcape had generated an average post-tax return on net capital employed of 12.9 per cent.[15]
