UBS analysts kicked off coverage of TKO Group Holdings Inc with a ‘Buy' rating and a 12-month target price of $123 per share, calling the combination of WWE and UFC "a rare pure-play in live sports with rights renewals and synergies on the horizon."   "We believe the merger of WWE and UFC will improve monetization through cost and revenue synergies and create an entity generating strong cash flows that will enable returns to shareholders and optionality for management to acquire other live sports properties," the analysts wrote.
