Poscoâs company name, Pohang Iron & Steel Co. Ltd, has been officially changed to âPosco.â? The name change was officially passed during the 34th Shareholdersâ Meeting recently held in the Seoul Posco Center. Posco’s previous official name was used since the company’s establishment on 1 April 1968. The recent name change to Posco is expected to raise the company’s international name recognition and consequently strengthen the company’s brand power. Also, by excluding the industry-specific term âsteelâ? from the official name, Posco expects the negative preconceptions and restrictions on future growth that could have been associated with the company’s name to be removed.
