ADNOC Drilling Company has appointed Abdulla Ateya Al Messabi as the new Chief Executive Officer (CEO), upon approval of the Board of Directors.

Al Messabi succeeds Abdulrahman Abdulla Al Seiari, who is retiring from the post after 45 years of service to the ADNOC Group and ADNOC Drilling at the end of this year. “He will remain in an advisory capacity through the year-end to support a smooth and seamless leadership transition,” the company said, sharing the transition news.

Adding, “Al Seiari’s retirement marks the culmination of a distinguished career spanning more than 45 years with ADNOC. As CEO of ADNOC Drilling, he led the company through a historic transformation, including its landmark initial public offering on the Abu Dhabi Securities Exchange, which was 31 times oversubscribed—a record at the time.

Under his leadership, ADNOC Drilling has evolved into a high-performing, technology-enabled, future-focused energy services company.”

Extending wishes to Al Seiari, His Excellency Dr. Sultan Al Jaber, ADNOC Managing Director and Group CEO and Chairman of ADNOC Drilling, said, “We extend our deep appreciation to Abdulrahman for more than four decades of distinguished service to ADNOC and ADNOC Drilling.

Under his leadership, the company has transformed into one of the world’s largest and most technologically advanced energy services providers. His commitment to operational excellence, safety, and national talent development has laid a strong foundation for continued success.”

The new CEO, Al Messabi, brings over 28 years of leadership experience across the energy sector. He most recently served the group in a key role and, prior to that, served ADNOC Sour Gas as CEO for over a year. He initially joined the group in 2020 as Unit Manager, Refining and Petrochemicals, and was later promoted to the CEO role for ADNOC Refining.

In other roles, he worked with Borouge as the Senior Vice President of the Technical Group and, before that, served the Ministry of Justice as Senior Administrative Officer. On the academic front, he holds a Bachelor of Science degree in Chemical Engineering from the United Arab Emirates University and holds key certifications in technology and operations from Borealis.
