Well, OP, wonder no more! Because TR has been selling financial data to MSFT for quite a while, yet there have been layoffs all along. This isn't going to move the needle.
Also, I ask: when was the last time you opened PPT or Excel or Word to check the financial markets? I thought so. The market synergies of deals like this are always overblown. There was a time when TR was going to leverage Learning, IP & Science, Healthcare, Legal and Financial to cross market everything to everyone! Oh, Happy Day! Except they never pulled it off. Even though the lack of cooperative business case prioritization between the SBUs would be enough to (and did) doom many of those "cross pollinating" initiatives, the fact is, the customers were lukewarm to the idea. No tax accountant has a pressing need for M&A League Tables, or Patent Search, or D--g Interaction Tables, on a daily basis. It was overkill to 95% of the collective customer base. Hence: Learning, gone. Healthcare, gone. F&R, gone.
Refinativ should slowly pare off niche parts of the business too. Sell the CM&A business to Factset or S&P. Sell FxAll & Tradeweb to the consortium of banks that use them. Sell what's left of Lipper to Broadridge or ADP. Move forward with a lean desktop and feeds platform with reliable trade-through capability that can compete on price with BBG. And get rid of all the high level professional meeting attendees who don't contribute, of which there are still plenty. For example:
I was once with the Head of Sales, and the Head of Client Specialists for my region. I don't remember why, but the head of sales asked the head of cs how many stocks were in the DJIA. She guessed 35. This is an executive responsible for over a hundred client facing professionals in a fintech firm.
