Following the announcement that ABB (ABB) plans to acquire Bernecker & Rainer Industrie- Elektronik, Wells Fargo analyst Richard Kwas says the deal should provide support for Rockwell Automation's (ROK) shares, and should be a positive read through for the latter. The acquisition fills gaps for ABB in discrete automation, the analyst notes, adding that ABB could become a "more formidable competitor" in discrete. Separately, Kwas acknowledges that he had thought that Bernecker & Rainer Industrie- Elektronik may have been a "good fit" for Emerson (EMR), which he expects to execute additional M&A later in the year.
