My organization has had many acquisitions over the past two years. Some were large and other small. We are recordkeepers for 401K plans. If an acquisition bring with it 5,000 plans and another bring with it 500 plans, it’s the same amount of integration work from an IT or HR perspective, for the most part.
Although due diligence was done, there are always unknown ‘things’ that come up and take time. Our integration teams try to prioritize, but it is frustrating when integration is more complicated for a smaller acquisition.
