Braskem SA (BAK) experienced a significant pre-market plunge of 5.08% following the release of its quarterly earnings results.

While the company's adjusted loss per share of 2 cents beat analyst estimates, the substantial revenue miss and reported net loss appear to have driven negative investor sentiment during the pre-market session.
