PLYMOUTH, Minn., August 5, 2013 – The Mosaic Company (NYSE: MOS) today announced that it has entered into a Shareholders’ Agreement with Saudi Arabian Mining Company (Ma’aden) and Saudi Basic Industries Corporation (SABIC) to participate in integrated phosphate production facilities in the Kingdom of Saudi Arabia. The companies have been working toward the agreement since a Heads of Agreement was signed in March. Ma’aden, Mosaic and SABIC will own 60, 25 and 15 percent of the joint venture, respectively. The estimated $7 billion greenfield project, to be known as Wa’ad Al Shamal, or Northern Promise, Phosphate Project, will be built in the northern region of Saudi Arabia at Wa’ad Al-Shammal Minerals Industrial City, and in Ras Al Khair Minerals Industrial City which is located on the east coast of Saudi Arabia. The highly cost-efficient project is expected to have a production capacity of 3.5 million tonnes of finished phosphate per year. Operations are expected to commence in late 2016.
