The U.S. equities market closed with contrasting movements on Friday, highlighted by a near 100-point increase in the Nasdaq Composite index. This mixed performance was punctuated by specific companies registering noteworthy gains, driven largely by company-specific news.

Leading the day’s advancements was Worthington Steel Inc (NYSE:WS), which saw its stock price leap by 6.9% to reach $41.43. This surge followed Worthington Steel's announcement of entering into a Business Combination Agreement with the German metal distributor Kloeckner & Co. The agreement outlines a voluntary public offer aimed at acquiring all outstanding shares of Kloeckner & Co at a price of 11 euros per share, roughly translating to $12.80. The move has garnered management backing, with plans in place for the current leadership at Kloeckner to continue post-transaction.
