An investment case in an African market is usually decided by three variables that sit outside the operating model. The first is currency: the regime a market operates, the availability of hard currency, and the mechanism by which earnings are repatriated. A business can perform exactly as forecast in local terms and still disappoint in the currency the investor reports in.
The second is regulation, and specifically the gap between the rule as written and the rule as administered. Licensing practice, tariff and pricing determination, local-content requirements and enforcement discretion are frequently more consequential than the headline framework, and they are rarely documented in a form that can be desk-researched.
The third is political economy: who holds the relevant decision, what interests sit around it, and how durable the current arrangement is across an electoral or leadership cycle. This is not a matter of country-risk scoring. It is a specific, answerable question about a specific sector, and the people who can answer it are the people who have operated inside it.
All three are knowable. None of them is reliably knowable from published material, which is the argument for primary expert research rather than a preference for it.
