What is the year-to-date margin performance and what is expected for Q4 margins given acquisitions' dilution and mix and ROE-related headwinds?
Management said the year-to-date margin is being pressured by acquisition-related dilution of “more than 2 full percentage points” (i.e., over ~200 bps) from recently completed deals. 1
They also referenced other drivers (including ROE-related growth headwinds, as the question notes), but in the excerpts the most explicit quantified components are the acquisition dilution and how margins have been performing sequentially within the year. 213
