Hanon Systems at 40: From Auto Parts to Data Center Cooling Powerhouse

SEOUL, South Korea – March 10, 2026 – Hanon Systems, a global pillar in automotive thermal management, is celebrating its 40th anniversary not just with a look back at four decades of engineering, but with a bold strategic leap forward. The company, now a key subsidiary of the Hankook & Company Group, has unveiled an ambitious plan to expand its expertise beyond the automotive chassis and into the burgeoning, high-stakes world of data center cooling and other key infrastructure industries.

Marking the milestone with a new anniversary logo, "40 Years Forward," the company signals that its legacy is the foundation for a significant transformation. While it will continue to innovate for vehicles, its new strategy involves a calculated diversification aimed at capturing growth in sectors where its core competency—managing heat efficiently—is becoming critically important. This pivot comes just over a year after its acquisition by Hankook, suggesting a new era of aggressive, strategic growth is underway.

The New Frontier: Cooling the Digital Age

Hanon Systems is targeting a market experiencing explosive growth: data center cooling. As the world’s demand for data, cloud computing, and artificial intelligence skyrockets, the servers that power this digital revolution are generating unprecedented levels of heat. This has turned thermal management from a back-end utility into a primary challenge for tech infrastructure, directly impacting performance, cost, and sustainability.

The global data center cooling market, valued at over $12 billion in 2026, is projected to grow dramatically, with some forecasts predicting a compound annual growth rate (CAGR) exceeding 15% to 20% over the next decade. This growth is driven by the need for more powerful, energy-efficient cooling solutions to handle the intense heat loads of high-performance computing (HPC) and AI hardware. Traditional air-cooling methods are proving insufficient and inefficient, pushing the industry toward advanced solutions like liquid cooling.

This is where Hanon Systems sees its opening. The company plans to leverage its deep expertise in high-efficiency fluid transport and thermal exchange, honed over decades in the demanding automotive sector, and apply it to this new vertical. The principles of managing battery temperature in an electric vehicle (EV) or cooling an engine are directly transferable to dissipating heat from server racks. The move would pit Hanon Systems against established players like Vertiv and Schneider Electric, but its proven track record in mass-producing reliable, high-performance thermal components could provide a significant competitive edge.

The Hankook Effect: A New Era of Growth

This strategic diversification is heavily influenced by Hanon Systems' new parent company, Hankook & Company Group, which finalized its acquisition in January 2025. The move was part of Hankook's broader vision to build a comprehensive high-tech mobility portfolio, encompassing tires, batteries, and now, thermal management. The acquisition brought Hanon Systems under the leadership of CEO Soo-Il Lee, who has been tasked with integrating Hankook's "successful DNA" and driving a new phase of qualitative growth.

The financial stability and strategic backing from Hankook appear to be a key catalyst. After a challenging period that saw its operating margin decline, Hanon Systems has shown signs of a robust turnaround. The company returned to net profitability in the third quarter of 2025 for the first time in six quarters and reported a significant 184.5% year-over-year increase in operating profit for the full year 2025, reaching KRW 271.8 billion on revenues of KRW 10.88 trillion. This financial strengthening provides a solid platform for investing in new ventures.

"The dedication of our employees, and their continued focus on quality and innovation have been the foundation of Hanon Systems' growth over the past four decades," said Soo-Il Lee, President and CEO of Hanon Systems, in a recent statement. "Our 40th anniversary is not only a celebration of our history, but a commitment to disciplined execution, financial stability, and sustainable long-term growth."

This commitment to disciplined execution is now being channeled into both enhancing operational efficiency in its core business and allocating strategic resources toward these next-generation technologies.

Reinforcing the Core and Expanding the Aftermarket

Even as it ventures into new territory, Hanon Systems is not abandoning its roots. The company remains a dominant force in automotive thermal management, particularly for the rapidly growing EV market. In 2024, parts for electric vehicles already accounted for 26% of its total sales, and a substantial portion of its massive order backlog is tied to EV platforms, underscoring its continued relevance and leadership in its primary industry.

Alongside its high-tech diversification, the company announced a second, more traditional growth strategy: strengthening its position in the global automotive aftermarket. This is a pragmatic move to capitalize on a vast and steady market. The global aftermarket, valued at over $670 billion in 2024, is projected to exceed $800 billion by 2030. This growth is fueled by a consistently aging global vehicle fleet, which requires more frequent repairs and replacement parts.

By bolstering its aftermarket presence, Hanon Systems can create a more resilient business model, balancing the long-term, high-risk, high-reward venture into data centers with the stable, predictable revenue streams from selling replacement parts for the millions of vehicles already on the road. This dual-pronged strategy showcases a company leveraging its 40-year history to both defend its core market and aggressively pursue the thermal management challenges of the future.

With a legacy of engineering excellence, the financial backing of a major conglomerate, and a clear vision for expansion, Hanon Systems is positioning itself to be a critical player in cooling not just the cars of tomorrow, but the digital infrastructure that will run the world.
