The letters stand for Gesellschaft mit beschränkter Haftung which, translated literally, means a 'company with limited liability'. GmbH companies are incorporated and, as such, are legal entities unto themselves. These companies must have a minimum of two partners and may be, but do not have to be, owned by a public company.

German companies that are publicly traded are designated as such by the letters 'AG' after the company name. 'AG' is an abbreviation for the German word Aktiengesellschaft, which literally translates to 'corporation' in English.
