The companies are: LCY Chemical, Solvay, Chang Chun Group, KPPC Advanced Chemicals (Kanto-PPC) and Topco Scientific.
The companies attributed the postponements to the slow progress on the TSMC and Intel plants, a shortage of construction workers and higher costs on materials and labour.
The slow progress on the Intel and TSMC plants has been attributed to the slow hand-out of the Chips Act money and the delays in Chips Act grants have been blamed on bureaucratic requirements relating to issues like diversity and inclusion.
Earlier today the White House announced $19.5 billion in grants and loans for Intel on top of the 25% investment tax deduction it will get for fab construction.
