Notes
Simmtech is a leading Korean memory packaging substrate maker, with significant exposure to DRAM and NAND demand cycles. The holding company structure was established after a 2015 spin-off separating Simmtech Holdings from operating subsidiary Simmtech Co. Growth is tied to memory packaging volumes, particularly mobile and server DRAM.
Simmtech Holdings filed its Q1 2026 quarterly report covering January 1 to March 31, 2026, marking the 40th fiscal year. As a pure holding company, it derives income from dividends, trademark royalties, and rental income from subsidiaries engaged primarily in PCB (Module and Substrate) manufacturing and sales. The consolidation scope remained unchanged at 17 subsidiaries (1 listed, 16 unlisted), with no new additions or removals during the period. The report reaffirms the corporate structure across Korea, China, Japan, Singapore, Malaysia, Taiwan, India, and other overseas entities without disclosing material new business developments in the opening sections. No credit rating changes or special listing matters were reported.
