Madison Square Garden Entertainment Corp. (MSGE) on Friday said it would move ahead with a spin-off of its live entertainment business and planned to complete that spin-off by the end of March. Executives for the company said it had confidentially filed an amended registration statement for the proposed deal, and said it expected to file a publicly available registration statement next month. Shares were unchanged after hours. MSG in December said it was weighing separating its live entertainment segment as part of a “revised” spin-off plan approved by its board. The spin-off would be structured as tax-free to stockholders, the company said.
