• The agreement includes the acquisition of a 51% stake in Lantania Aguas by the Emirati giant

• Post transaction completion, the business will operate under the name Lantania NMDC Water

Lantania and NMDC Group (ADX: NMDC), one of the largest engineering and construction groups in the Middle
East, have signed an acquisition agreement to create a new international benchmark in the water sector. Under
the agreement, NMDC Group will acquire 51% of Lantania Aguas, the Lantania Group’s subsidiary specialized
in desalination, water treatment, and purification projects. The Spanish Group will retain the remaining 49% of
the business, which will operate under the name Lantania NMDC Water (post completion). The company will
maintain its headquarters in Seville, have a regional office in Abu Dhabi, and continue to be managed by the
current Lantania Aguas executive team, led by Pedro Almagro as CEO. The completion of the transaction is
subject to customary regulatory approvals.

Given the current challenges posed by water scarcity and its effective management, both companies are joining
forces in a move that strengthens their shared commitment to providing effective solutions for the most critical
needs of clients and communities worldwide.

Lantania NMDC Water will combine NMDC Group’s commercial strength and technical capabilities with
Lantania’s experience, credentials, and expertise in desalination, wastewater treatment, and water reuse, as
well as in large-scale industrial projects, to create a leading global operator in water infrastructure. The
agreement establishes a joint-management structure that will enable the business to strengthen its
technological, financial, and operational capacity, boosting its presence in strategic markets such as the Middle
East, North Africa, Europe, South and Southeast Asia, and Latin America.

The company, comprising over 300 professionals, begins its operations with a project backlog under execution
across several countries, totaling EUR450 million, a solid foundation that supports its growth outlook.

“This alliance marks a milestone in the history of our company and a turning point for Lantania Aguas,” said
Federico Ávila, Chairman and CEO of the Lantania Group. “NMDC Group’s technical and commercial strength,
combined with Lantania’s engineering capabilities and experience in this market, will enable us to jointly
undertake major projects and establish a global benchmark in sustainable water solutions. We share the same vision, focused on promoting innovation, energy efficiency, and sustainability in each of our projects,
contributing in a tangible way to global water security,” Ávila added.

Eng. Yasser Zaghloul, Group CEO, NMDC Group, said: “This acquisition marks NMDC Group’s first entry to the
European market as we are set to export UAE-grown capabilities and scale to complement Lantania’s proven
expertise. It also aligns with our strategic expansion objectives and diversifies our portfolio across many of the
world’s most critical industries and markets. NMDC Group has long recognized the global challenges posed to
water, and through Lantania NMDC Water, we affirm our commitment to harness innovation and advanced
solutions to a more sustainable future.”
