Paris, November 3, 2021 - Today, Nexans published its financial information for the third quarter of 2021. Commenting on the Group's achievements, Christopher Guérin, Nexans' Chief Executive Officer, said: "Nexans confirms its solid trajectory and topline momentum supported by new value creation levers around its mission: Electrify the future. Thanks to our amplified solutions, we have initiated our strategic ambition 2022-2024 and reached first successes as our backlog is steadily up year-on-year and we confirm our 2021 financial guidance upgraded in July. Nexans has a sound and clear roadmap to become the Pure player of Electrification. In the last weeks, we have:

• Inaugurated with our key stakeholders our new vessel Nexans Aurora, an important enabler to build a safer, more sustainable and inclusive global energy system. This leading-edge vessel will contribute to unlocking the huge potential of offshore renewable energy and subsea interconnection alongside our unique subsea cable manufacturing plant in Charleston, USA.
• Reached a first milestone of our new strategic ambition by announcing September 10th a Share Purchase Agreement with Xignux SA to acquire Centelsa4, a premium cable maker in Latin America. This world class and iconic South American operation will further contribute to Nexans' ability to serve renewable projects in the Andean Region.
• Continued to launch innovations to support further value creation while also reinforcing our ESG commitments by hosting Nexans' second Climate Day and proposing the election of Laura Bernardelli as an independent director to the shareholders' meeting.

Nexans strives to best serve customer needs while engaging in a better future and focusing on value growth for all its stakeholders."
