You have "foundation markets" and not "Foundation Markets", so I don't think they are talking about a company, bank...
They list 3 markets they are interested in:
win markets
growth markets
foundation markets
in my opinion they are talking about the different markets in the world economy.
In these slides 3 types of markets are mentioned
https://issuu.com/360com/docs/360com082_2015

international lead markets
high growth markets
foundation markets (the rest of the world)

so in this case: foundation markets=mercati del resto del mondo


Or you could check this article:

https://www.adaci.it/458-internazionalizzazione-degli-acquis...

Matrice di Qualità dei Mercati FTSE

> Developed Markets (Mercati evoluti)
> Advanced Emerging Markets (Mercati Emergenti Avanzati)
> Secondary Emerging Markets (Mercati Emergenti Secondari)
> Frontier Markets (Mercati di Frontiera)

and maybe you could translate: "mercati emergenti secondari e mercati di frontiera"

Hope it helps
