Connecting Value, Building the Future

Welcome, and thank you for visiting TMC.

 Celebrating its 35th anniversary, TMC has grown from our beginnings into a leading
cable manufacturer. Through continuous challenges and technological innovation, we
have established ourselves as a global leader, achieving the No.1 market share in
marine and offshore cables in South Korea. Built on decades of accumulated expertise,
superior quality, and strong customer trust, we have secured a distinct competitive
position as a global top-tier company.

 Today, we are entering a transformative era driven by AI, where infrastructure is rapidly
evolving. Demand for power and data is surging, and energy and information
infrastructure are becoming critical pillars of future competitiveness. These changes
present new opportunities for TMC and mark a turning point toward our next stage of
growth.

 Based on our strong global competitiveness in marine and offshore cables, TMC is
expanding our portfolio into high-value-added segments, including nuclear power
cables, data center and fiber-optic cables, as well as defense cables. By leveraging our
differentiated technologies in high-reliability, safety-critical infrastructure, we will
continue to strengthen our global presence. This expansion goes beyond business
growth, reinforcing the infrastructure that connects energy and information while
creating broader societal value.

 Moving forward, TMC will continue to deliver value to our customers through
unmatched expertise and grow as a globally competitive company enabling the flow of
energy and information.

We sincerely appreciate your continued support.
Thank you.
