Looks like you have a potentially great business for corporate compliance, if you can answer with plausibly high confidence (or indemnify?).
I only occasionally research companies, and it's from an engineering&product perspective, aside from corporate ownership compliance. (For example, I was asked to vet a little-known company as a prospective partner, for building our cloud infrastructure atop theirs. One of the first rapid low-cost, high-value things I could do, besides looking at their docs and trying their demos, was to skim through the history of business news about them.)
