Cemex is owned by public shareholders and global institutional investors, since the company trades openly on both the Mexican and New York stock exchanges with no single controlling owner today.
Cemex has grown from a single Mexican cement plant into one of the largest building materials companies in the world, supplying concrete and cement to construction projects across dozens of countries.
The company was founded in 1906 in Monterrey, Mexico, and the Zambrano family guided its growth for generations before the business expanded well beyond family control.
So how did a family founded cement company become a publicly traded global giant with shareholders spread across the world?
This guide will explore who owns Cemex today, what role the Zambrano family still plays, who the largest institutional shareholders are, and how Cemex compares to other major concrete producers.
So let’s get started.

Who Owns Cemex in 2026
Cemex is a large, publicly traded company listed on the Mexican Stock Exchange and the New York Stock Exchange, meaning ownership is spread across public shareholders rather than concentrated in one owner.
More than 80 percent of the company’s float is held by institutional investors, including major asset managers like BlackRock and The Vanguard Group.
The Zambrano Family Legacy
Cemex was founded in 1906 in Monterrey, Mexico, and the Zambrano family led the company through much of its early growth and eventual global expansion.
Lorenzo Zambrano Gutierrez became a defining figure in the company’s history, steering major decisions that transformed Cemex from a regional cement maker into an international operator, according to Pestel Analysis.
Today Chairman Rogelio Zambrano Lozano remains the most visible link to that family legacy, even though the family no longer holds a controlling equity stake.
Who Are the Largest Institutional Shareholders
BlackRock holds roughly 6.2 percent of Cemex shares, making it one of the very largest single institutional shareholders in the entire company.
The Vanguard Group holds close to 4.5 percent, with State Street and Dodge and Cox also appearing among the notable institutional holders listed in recent filings.
How Cemex Became a Global Company
A pivotal 1987 merger helped set the stage for decades of expansion, positioning Cemex to acquire operations across Latin America, Europe, Asia, and the United States.
That international growth turned a single country cement business into one of the largest building materials suppliers on the planet, with operations spanning dozens of countries today.
Cemex vs Other Concrete Producers
Cemex competes with a mix of large multinational suppliers and smaller regional family owned operators, standing apart for its sheer global scale and stock market presence.
Unlike privately held regional producers such as SRM Concrete, Cemex answers to public shareholders and must report quarterly earnings just like any other listed company.
Cemex also supplies raw materials and finished products that support heavy machinery operators using brands like Bobcat and Rotary Lifts on job sites around the world.
Is Cemex Good Quality?
Cemex has built a strong global reputation for reliable cement and concrete products, supplying materials for major infrastructure projects and large scale construction efforts across multiple continents.
The company’s scale allows it to invest heavily in research and sustainable production methods, an advantage smaller regional producers often cannot match.
