Hi Yumi,
Early in my career, I was involved in some due diligence as a financial analyst. This was in the early 2000s, when technology wasn’t anywhere near where it is today. It was a manual process of collecting vast amounts of information in a limited physical space and time, not like it is today with virtual data rooms. These were the biggest challenges as a “data collector.”
From my readings, challenges today could include:
– Having “good” information to make a reasonable valuation estimate if the target is a small private company.
– Having the resources, as the acquirer, to conduct a thorough due diligence of all aspects, not only the financials.
– Having the internal expertise to conduct proper due diligence. Relying too much on outside advisors could be a problem if the internal team is not experienced enough.
Best,
Peter
