Koç Group is Turkey's leading conglomerate. The Group has been a driving force of the Turkish economy with total sales that make up about 9% of Turkey’s GDP and exports that comprise 11% of Turkey’s total exports. As of 2009, Koç Holding is the only Turkish company in the Fortune Global 500 list of companies, in the 273th place. In addition to its leading market positions in low-penetrated consumer driven sectors, its extensive distribution network, which is yet the largest in Turkey with over 12,000 points of reach and the largest customer database with strong CRM capabilities, the Group is also active abroad with about 25% of revenues stemming from international operations and exports.

As part of the restructuring program adopted during the last several years, Koç Holding went through a significant portfolio shift, with a very successful and pro-active divestiture plan and major acquisitions in the core sectors. As a result, the Group is operating in a less number of core sectors, focusing more on efficiency, margin growth and shareholder value.

Following the acquisition of Tüpraş, Turkey’s sole refiner and the largest refinery in Emerging Europe, Koç Group enhanced its place as Turkey's foremost energy player with leading positions in the Turkish energy sector, maximizing synergies among its petroleum products distribution network and LPG distribution business. Currently, Koç Group is the leader in the LPG sector and has been growing aggressively in fuel retailing as the number three player.

Koç Group manufactures about half of all the motor vehicles in Turkey and is also responsible for about 50% of all Turkish motor vehicle exports. Through strong and committed joint venture partnerships with major international automakers, such as Ford, Fiat and Case New Holland, Koç Group is the largest automotive player in Turkey. The Group, which is aiming to become one of the major manufacturing hubs in the world for leading international brands, offers low cost high quality manufacturing capabilities while also possessing the largest automotive retail network in Turkey.

Koç Group is the undisputable market leader in consumer durables with around 54% market share in Turkey. The largest sales and after-sales service network combined with high quality, innovative products and competitive pricing are the main drivers of this success. Meanwhile, the Group is also replicating its domestic success in the international markets through its exclusive distribution network and low-cost manufacturing centers that are located in Turkey, Romania, Russia and China which are used to serve their respective domestic markets and the neighboring countries.

Koç Group, following its partnership with Unicredit of Italy, has now become a major player in the Turkish financial sector with the acquisition of Yapi Kredi Bank, the third largest private bank in Turkey. The combined efforts of Koç and Unicredit, with Unicredit's expertise in retail banking and risk management and Koç Group's long-standing strong reputation and knowledge of the local market work to add value to Yapı Kredi's strong banking franchise.

Koç Group companies that operate in the food, retail, tourism, information technology and construction sectors are classified under the "Other" segment. Tat Konserve, the leader in tomato products; Koçtaş, the leader in DIY retailing; Setur and Divan Group, the leaders in the tourism sector; Setur Marinas that represent Turkey's highest marina capacity; RMK Marine, a pioneer in ship and yacht building; KoçSistem, the leader in information technology solutions and Koç.net, the leader in alternative telecom services are among the companies that operate in this segment.
