Ma'aden Wa'ad Al Shamal Phosphate Company runs the second of Saudi Arabia's integrated phosphate fertiliser chains. The joint venture agreement was concluded in August 2013 for an initial 25 year term, bringing together the Saudi Arabian Mining Company (Ma'aden) with Saudi Basic Industries Corporation and the American fertiliser producer Mosaic, which exited in December 2024. Its ore comes from the Al-Khabra mine in the Umm Wu'al area of the northern border region and is upgraded at Wa'ad Al-Shamal Mineral Industrial City in a beneficiation plant designed for 5 million tonnes a year of concentrate, alongside a sulphuric acid plant of 5 million tonnes a year and a phosphoric acid plant of 1.5 million tonnes a year of P2O5. A railway carries the intermediate product to Ras Al-Khair on the Gulf coast, where the venture runs an ammonia plant of roughly 1.1 million tonnes a year and a granulation plant that makes compound phosphate fertilisers. Ammonia production began in January 2017 and fertiliser production in December 2018.

The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from

What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Ma'aden Wa'ad Al Shamal Phosphate Company (MWSPC) where a holder stated one, and are missing where no holder did.
