Stock feed and rendering company Ridley is waiting to hear from California-based private equity firm AGR Partners after AGR bought a 19.5% stake in the company from long-term holder GPG. GPG, which is in the process of winding down an international investment portfolio, reported $54 million proceeds from the sale of 19.5% of its 23% stake in Ridley to AGR Partners. AGR has expressed an interest in investing in the company as markets increasingly focus on the opportunities from a growing and increasingly wealthy population in Asia, North Africa and the Middle East and as it invests in companies that it views as indispensable assets to the food chain.
