and modernisation of the enterprise occurred in the 1960s, 70s and 80s. In 1991 the plants were transformed into a joint-stock S.A. company of the State Treasury. In the period of re-investment (2001-2007) and unsuccessful attempts of privatisation (2001), on 5 March 2006 the management board of Zakłady Azotowe in Tarnów-Mościce S.A. (currently Grupa Azoty S.A.) decided to enter the Warsaw Stock Exchange. From a time perceptive, the company debut on the Stock Exchange on 30 June 2008 turned out to be “spiritus movens” not only for its further development, but also for consolidation of the Polish chemical industry. In May 2010 the Grupa Azoty took on the function of the Polish chemical industry consolidator. In 2014 the process of integration of two largest Polish chemical plants was completed. Thus the Grupa Azoty Capital Group was established, with the dominant unit, Grupa Azoty S.A. based in Tarnów. Grupa Azoty includes other businesses such as Grupa Azoty POLICE, Grupa Azoty PUŁAWY, Grupa Azoty ZAK, Grupa Azoty SIARKOPOL and foreign acquisitions allowed to also include a German company Grupa Azoty ATT Polymers GmbH in the portfolio. Currently, the Grupa Azoty incorporates or is associated with over fifty other entities where it is a minority capital shareholder. Grupa Azoty is included in the following indices WIG, WIG30, mWIG 40, WIG-Poland, WIG-CHEMIA, Respect Index of the Warsaw Stock Exchange as well as International MSCI Emerging Markets and the FTSE Global Equity Index Series Emerging Markets.
