About LyondellBasell Industries N.V. (LYB)
LyondellBasell was formed through a merger between Basell (a joint venture between BASF and Shell) and Lyondell, which was a major chemical producer dating back to the 1950s. Notably, the firm filed for bankruptcy in 2009 after the merger, following a heavy debt burden taken on for the 2007 merger. It was reorganized as LyondellBasell NV and relisted in 2010. LyondellBasell has five reportable segments, after exiting refining in 2025: olefins and polyolefins Americas (O&P A), olefins and polyolefins Europe-Asia-International (O&P EAI), intermediates and derivatives (I&D), advanced polymer solutions (APS), and technology.
