Form 4 Ingevity Corp For: 3 March

South Korean stock trading was temporarily halted on March 3, 2026, as the benchmark KOSPI index plunged over 11% amid escalating geopolitical tensions in the Middle East and concerning economic data from China. The dramatic market intervention came as Asian stocks broadly declined, with investors reacting to rising fears of inflation sparked by the widening conflict involving Iran. The South Korean market's sharp downturn reflected growing anxiety among regional investors about the potential economic consequences of escalating hostilities in the Middle East, which threatens to disrupt global energy supplies and supply chains. Beyond South Korea, other Asian markets also faced significant selling pressure as mixed China PMI data added to the uncertain economic outlook, creating a perfect storm of negative sentiment across the region.
