Prysmian to strengthen its global leadership in submarine cables as Transmission accelerates towards full vertical integration

Acquisition of Spain-based ACSM brings subsea surveying, seabed preparation and new installation solutions in-house

Prysmian's fleet is expanding, following its recent acquisition of Acsm, a Spanish company specializing in submarine cable installation solutions, including marine surveying, route planning and seabed preparation, with more than 20 years of experience in the sector the The deal is valued at €169 million (including a €24 million investment in a vessel to be delivered to Acsm in the fourth quarter of 2025). The transaction will be financed using available cash in Prysmian's balance sheet. The deal is expected to close by February.

Strengthen Prysmian's global leadership in submarine cables

ACSM, headquartered in Vigo, Spain, has been operating in 60 countries for over 20 years, with over 350 employees and a track record of hundreds of completed submarine operations. In 2024, ACSM revenues amounted to €62 million and EBITDA was €22 million. As of December 31, 2024, ACSM's net debt was €14.4 million. "The transaction will strengthen Prysmian's global leadership in submarine cables. The integration of ACSM will broaden Prysmian's range of solutions for energy and telecom customers, offering a single source and accelerating the full vertical integration of its submarine operations, contributing industry-leading know-how and assets," the statement added.

ACSM’s role in submarine cable installation

Acsm's solutions and resources are essential for submarine cable installation, as projects require pre-installation surveys to facilitate an effective, timely, and safe process, including route planning, and post-installation surveys to ensure cable operation. After pre-installation surveys, preparatory activities must be carried out and often obstacles must be overcome, before or during cable installation. These include activities such as route clearance, rock and debris removal, unexploded ordnance removal, dredging to remove obstacles, and so-called "mattress installation," in which concrete blocks are placed around the cable for safety. To carry out these activities, Acsm has a suite of unmanned underwater robots (ROVs), trenching machines, and survey equipment, as well as three vessels.

Offshore renewable energy,

These solutions complement Prysmian's global leadership in submarine cable installation, including burial tools and vessels. Acsm has provided Prysmian with surveying and route preparation services for several major projects. Prysmian will also benefit from Acsm's experience in offshore renewable energy, recovery and rescue, and research and development projects.

When the world thinks of submarine cables, they think of Prysmian,

Raul Gil, EVP Transmission at Prysmian, said: “When the world thinks of submarine cables, they think of Prysmian, and this acquisition is another significant step forward. We gain the know-how of over 350 experts in subsea surveying and preparation, three dedicated vessels and essential equipment while strengthening our offer as a one-stop shop for customers. Combining our global leadership and capabilities, with ACSM’s expertise and solutions, we will deliver optimized installation and burial processes that will set the standard for cost-effectiveness, the speed of installation and the most robust protection. Submarine cables are strategic assets, and security is a differentiator for our customers, and this acquisition further strengthens the range of solutions available to keep electricity and data safe under the sea.”

Deliver highly reliable subsea services.

These solutions complement Prysmian’s global leadership in submarine cable installation including burial tools and vessels. ACSM has been a supplier to Prysmian in the delivery of surveying and route-preparation services for several important projects. Prysmian will also benefit from ACSM’s expertise in offshore renewable energy projects, salvage and rescue, and R&D.

“We are very pleased to begin this new chapter together with Prysmian,” commented Jose Cubeiro, ACSM CEO. “ACSM’s growth has been built on our unwavering commitment to operational excellence, the expertise of our teams, and a fleet of state-of-the-art vessels that enable us to deliver highly reliable subsea services. Joining forces with a global leader like Prysmian will allow us to further strengthen these capabilities, ensuring we continue to provide outstanding value to our partners and clients worldwide.”
