Jeil Pharma Holdings is a pure holding company overseeing subsidiaries including Jeil Pharmaceutical and Jeil Health Science, with group earnings heavily dependent on the business structure of core subsidiary Jeil Pharmaceutical.
Jeil Pharmaceutical has historically operated as a distribution-heavy business relying on products sourced from multinational drugmakers, with distributed-product sales accounting for 68.9% of revenue in 2024, far exceeding the 29.4% share of self-developed products.
Starting in 2025, the company discontinued distribution of three Viatris pain and anti-inflammatory products, Lyrica, Neurontin and Celebrex, making a reduction in distributed-product sales unavoidable.
In contrast, its self-developed acid-suppressing new drug Jaqubo was approved as Korea's 37th domestically developed new drug in April 2024 and launched in October that year, generating KRW 25.6bn in sales in the first half of 2025, or 8.5% of total revenue.
As a result, Jeil Pharmaceutical's own-product revenue share rose sharply from 29.4% in 2024 to 41.1% in the first half of 2025, while the distributed-goods share fell from 68.9% to 57.9% over the same period.
Jaqubo expanded its distribution network through a co-marketing agreement with Dong-A ST beginning September 2025, running for three years through October 2027 with a targeted sales amount of KRW 189.7bn.
New drug development is handled by research subsidiary Onconic Therapeutics, which Jeil Pharmaceutical established as a wholly owned entity in 2020 and which listed on KOSDAQ in December 2024; Jeil Pharmaceutical currently holds roughly a 45% stake, making Onconic a grandchild company under the holding structure.
Onconic combines licensing revenue from Jaqubo with clinical development of oncology candidate Nesuparib, serving as the external showcase for the group's new drug development capabilities.
