Based in Houston, Texas, the company maintains a global footprint across more than 70 countries and a workforce representing roughly 130 nationalities. With around 40,000 employees, it ranks among the largest providers in its field.

This move reflects ongoing efforts to enhance digital solutions alongside its traditional service offerings.
