The stock reached an intraday high of $13.68, marking its 52-week high, before settling near closing levels. Today's rise builds on momentum from the company's mid-June announcement to spin off its Streaming & Studios and Global Networks divisions, a strategic restructuring plan that continues to progress steadily.
