US: USG has rejected a proposal by Germany’s Knauf to buy all of its shares for US$42/share in cash or for around US$5.9bn. Jennifer Scanlon, president and chief executive officer of USG, described the offer as ‘wholly inadequate’ and said that it ‘substantially’ undervalued the company. She added that USG had discussed the proposal on the telephone with Knauf in December 2017 and met in mid-March 2018. Knauf submitted a revised proposal around the same time.
