Psomagen was established in 2004 in Maryland, U.S. as Macrogen's American subsidiary and became the first foreign company to list on KOSDAQ under the technology special listing track in 2020.
Its core businesses are next-generation sequencing (NGS) and first-generation Sanger sequencing (CES) services; based on previously disclosed figures, NGS accounted for roughly 66% of revenue, CES about 27%, and direct-to-consumer (DTC) genetic testing about 7%, though the most recent segment mix has not been separately confirmed.
The company subsequently expanded into single-cell analysis in 2021, proteomics in 2022, and third-generation long-read sequencing in 2023, positioning itself as a multi-omics total-solution provider in North America. Its major clients include the U.S. National Institutes of Health (NIH), the Michael J.
Fox Foundation (Parkinson's GP2 project), Moderna, AstraZeneca, GSK, and the Chan Zuckerberg Initiative, with multi-year contracts from these institutions underpinning its revenue base.
Psomagen has renewed an annual contract worth roughly KRW 8.3 billion with Moderna, accumulating over KRW 20 billion in revenue from that relationship over three years, while separately securing an KRW 8.3 billion Parkinson's genomics contract with the Michael J.
Fox Foundation and a roughly KRW 10 billion Alzheimer's-related contract with NIH. Macrogen remains the controlling shareholder, holding about 36.88% as of the third quarter of 2023, with combined related-party ownership exceeding half, though the current shareholding structure requires separate confirmation.
In the competitive landscape, China-based Novogene—often cited as the world's largest genomic sequencing company—has reportedly used Psomagen as a reference point in its own online advertising, which some in the industry interpret as a sign of Psomagen's rising brand recognition in the U.S. market.
Kean Health, a home-wellness testing subsidiary Psomagen invested in during 2023, had a portion of its equity stake sold in the first half of 2026, removing it from the consolidation scope.
