07 Apr 2026 22:00 CEST

Luxembourg - 7 April 2026 - Subsea 7 S.A. (Oslo Børs: SUBC, ADR: SUBCY) today
announced the signing of a strategic collaboration agreement between PETRONAS
Suriname E&P B.V. ("PETRONAS Suriname"), a subsidiary of PETRONAS and Subsea
Integration Alliance (SIA), which comprises Subsea7 and SLB OneSubsea.  The
agreement creates a long-term framework for close collaboration on field
development projects in Suriname.

Through early engagement and integrated execution, the collaboration aims to
simplify complex procurement processes, reduce total development costs and
enhance delivery certainty. The optimisation of project timelines, combined with
a reduction in execution risk, will enhance project economics and unlock
opportunities across a portfolio of prospects in Suriname.

Under the framework, SIA will provide pre-FEED, FEED and engineering,
procurement, construction, installation and commissioning (EPCIC) solutions for
multiple prospective projects. The scope includes subsea umbilical, riser and
flowlines (SURF) from Subsea7, and subsea production systems (SPS) from SLB
OneSubsea.

Craig Broussard, Senior Vice President for Subsea7, said: "We are proud to be
working with PETRONAS Suriname through this strategic agreement to establish
strong, sustainable foundations in Suriname that will support growth in this
emerging frontier basin. The agreement builds on our track record of
collaborating with our clients to drive value creation through the delivery of
optimised development solutions. We are excited to see the positive impact this
work will have in the region."

Olivier Blaringhem, CEO of Subsea Integration Alliance, said: "This is an
exciting and important step for the development of the significant opportunities
of PETRONAS Suriname in Suriname's frontier basins. The combined deepwater
expertise and collaborative, agile approach of Subsea7 and SLB OneSubsea, will
maximize value as the developments secure vital energy resources in the region."
