Atom Achieves 101% Oversubscription in Rights Offering... Accelerates Marine AI Data Center Business with Seawater Cooling Technology

The rights offering conducted by KOSDAQ-listed Atom has been a success, with strong participation from existing shareholders. The company plans to leverage the capital raised and increased market confidence to accelerate the expansion of its “marine AI data center” business.

According to Atom on April 24, a total of 4,044,423 shares were subscribed for by existing shareholders, exceeding the planned issuance of 4 million shares and resulting in a subscription rate of 101.11%. Achieving oversubscription despite ongoing uncertainty in the capital markets is seen as a reflection of confidence in Atom’s stable electric vehicle parts business as well as expectations for its new marine AI data center venture.

The performance of DST, Atom’s subsidiary considered a key pillar of the company’s value, has also been positive. DST, in which Atom holds a 50% stake, benefited from a boom in the shipbuilding industry and recorded sales of 62 billion won, operating profit of 3.7 billion won, and net profit of 1.9 billion won in 2025. As the exclusive vendor for Hanwha Engine and a key partner of HD Hyundai Heavy Industries, DST is targeting sales of 70 billion won this year. Atom aims to maximize synergy by combining these proven results with its own high-efficiency power technology.

The primary focus for the newly raised funds will be on data center cooling technology utilizing seawater. Unlike conventional land-based data centers, which face challenges due to massive power consumption, cooling infrastructure, and water supply issues, Atom and DST are working to overcome these barriers by using seawater as a coolant. This approach enables more effective control of server heat, significantly reduces power consumption for cooling, and provides greater flexibility in site selection.

Moreover, the integration of Atom’s high-efficiency transformer technology with DST’s expertise in marine environmental solutions further maximizes energy efficiency. In addition, the inclusion of AI server and fire response technologies from GlobalTopNet has resulted in a marine AI infrastructure system that is both highly efficient and stable.

Through these efforts, Atom is seeking to transform itself from a company focused mainly on parts supply into a high-value-added platform company that encompasses both the construction and operation of data centers.

A company representative stated, “The results of this rights offering demonstrate the market’s confidence in our technological competitiveness and the stable performance of DST. We will secure new growth drivers and enhance corporate value through seawater-cooled data centers.” The representative added, “We will also work to enhance shareholder value based on our secured technological capabilities and solid business foundation.”
