His fortune is derived from a 38.8-percent stake in Netherlands-based OCI N.V. and a six-percent stake in German sportswear behemoth Adidas.
Sawiris' net worth reached $7.45 billion at the end of the month.
The billion-dollar bump in his net worth is due to the company's year-to-date gains.
The billionaire's net worth has risen by $738 million since the start of the year.
The loss is directly linked to the performance of the German sportswear behemoth Adidas.
Meanwhile, his stake in German sportswear behemoth Adidas is valued at $2.59 billion.
With a total net worth of over $6.6 billion, Sawiris remains the richest man in Egypt and the 389th richest man in the world.
Sawiris had a net worth of $6.5 billion at the start of February.
The surge is largely due to gains in his shares in Adidas and OCI N.V.
The company has announced a potential move to list on the Abu Dhabi Stock Exchange.
