"Our plan going forward is to pursue a simpler and more direct separation, which is the best path to unlock the full value of Teck for our shareholders," Teck Resources CEO Jonathan Price said in a statement. Teck has been trying to thwart an unsolicited takeover attempt by Swiss commodities trader Glencore. Shares of Teck Resources climbed as much as 7% in pre-market trading Wednesday following the company's surprise announcement. As well, Teck revealed unaudited financial results for its first quarter of 2023, showing revenue of $3.79 billion, down from $4.62 billion a year earlier.
