One of the most important steps in any acquisition is due diligence, which starts with your due diligence request list. This data gathering process helps provide assurance that there are no skeletons in the closet that could come back to bite you later on. According to The Institute for Mergers, Acquisitions and Alliances, “not anticipating foreseeable events” drives 39% of M&A failures. Let’s do all we can to prevent your acquisition from being in that category.
In this article, we’ll cover a 79 point document request checklist to help you evaluate a potential acquisition target. I’ll also walk through some potential red flags to keep an eye out for.
Due Diligence Request List: Checklist for Buying a Business
Each deal will be different, and you’ll need to tailor your due diligence request list to the specific transaction. With that said, there are certain key themes that should be on every list.
Due diligence can be a long and complex process, but it’s critical to be thorough and patient. A detailed review will help mitigate the risk of any surprises later on and give you a better understanding of what you’re getting yourself into.
As PwC says, now more than ever there is a “greater need to perform robust due diligence – both deeper and beyond traditional areas.”
This checklist will help you make sure that you’re asking all the right questions and getting the information you need to make an informed decision about whether or not to move forward in the process.
As always, consult with your professional M&A advisors (accountants, lawyers, etc.) to ensure that you’re covering all of your bases.
