There is one clear winner on Wall Street on the Walgreens-Rite Aid mega deal
Swiss bank UBS is the sole advisor to the buyer, Walgreen, and is the sole provider of bridge financing for the deal.
That should generate a monster payday, totaling up to $65 million according to Jeffery Nassof, with M&A consulting firm Freeman & Co.
He told Business Insider that advisory fees should come in at around $25 million. The bridge financing for the deal could net the bank another $25 million to $40 million, he said.
Rite Aid shares soared more than 40% on Tuesday after The Wall Street Journal reported that a deal was close. The companies will host a conference call on Wednesday morning to discuss the transaction.
The deal marks a big win for UBS, which ranked 11 for US M&A prior to the deal's announcement, with about 11% of market share.
The deal is also a win for Citigroup, which is advising Rite Aid on the transaction. It has become a relative rarity to have just one adviser on either side on such big deals.
The bank was not immediately available for comment.
