Greystone Partners Business Overview

Greystone was incorporated as a public company on 27 January 2009. It is a listed investment company that focuses primarily on unlisted investment opportunities, i.e. the private equity asset class. The Company’s aim and objective is to achieve superior long term capital appreciation through majority or minority equity stakes across a portfolio of investments. Greystone, through its network of business associates, has the ability to leverage off its strong relationships within the business community to identify and execute on the most attractive of investment opportunities.


Although the Company’s main focus is unlisted investments, the Company’s investment mandate allows it to invest in a variety of instruments from pure debt, structured products, quasi equity funding, unlisted equity and listed equity investments. This flexibility provides Greystone with the ability to structure investments that limit downside risk whilst enabling the opportunity to achieve superior returns.

The Company’s primary investment geography is in the Kingdom of Eswatini. Where opportunities are unavailable, there may be a case for investing elsewhere within the Common Monetary Area (“CMA”).

Through the Directors, the Manager and the members of Greystone’s investment committee, the Company has extensive and complimentary backgrounds in public and private investing, principal investing, corporate finance, financial modelling, structured finance and financial engineering with over 50 years combined investment and business management experience in Africa. These skills have enabled Greystone to develop a successful long term track record.

The existing portfolio is currently well diversified. Strategically, Greystone targets businesses which fits the criteria of being clearly understood, management that has significant “skin in the game”, companies which generates high returns on equity and consistent growth in after-tax profits, compelling business models with a revenue “moat” and high growth potential.
