Mars ditches blue, brown in new dye-free M&M’s for U.S.

Mars has completed its acquisition of Kellanova, ending Kellanova’s run as a standalone, publicly traded snacks giant. If you owned Kellanova heading into the merger’s close, the key headline is simple: your shares were converted into a cash right of $83.50 per share. Trading in the stock was halted, and the company initiated the formal steps to remove the shares from exchange listing and ultimately wind down ongoing SEC reporting. SEC+2SEC+2

Mars has completed its acquisition of Kellanova, and each eligible share was converted into the right to receive $83.50 in cash, with trading halted and delisting actions underway. SEC+1
