Deutsche not seeing Pfizer buying Bristol-Myers at this time Following yesterday's speculation of a potential deal, Deutsche Bank analyst Gregg Gilbert said he would be surprised to see Pfizer (PFE) make a move on Bristol-Myers Squibb (BMY) at this stage. Such an acquisition "would represent a very large and concentrated opportunity/risk on immuno-oncology, an area fraught with near-term uncertainty," Gilbert told investors last night in a research note. He believes that if Pfizer were to use $90B for a deal, it would prefer to acquire a more diverse set of value drivers. The analyst keeps a Hold rating on Bristol and Buy rating on Pfizer. Bristol shares rose 3% yesterday to $53.71 amid speculation of a potential takeover. The conjecture had Roche (RHHBY), Novartis (NVS) and Pfizer potentially looking into a bid for Bristol.
