TLB’s Q3 Operating Profit Jumps 92% as SOCAMM2 Ramps Up

What happened

Memory substrate maker TLB said on Nov. 5 that third-quarter consolidated revenue rose 36.4% year-on-year to 93.965 billion won and operating profit surged 91.8% to 16.595 billion won, posting record quarterly revenue; revenue rose 6.5% and operating profit climbed 29.9% from the previous quarter, with operating margin at 17.7%, up 5.1 percentage points year-on-year and 3.2 percentage points quarter-on-quarter. The growth was driven by expanded shipments of SOCAMM2 substrates for AI servers; the company said the larger share of higher-value products improved its product mix and boosted profitability. SOCAMM2 is a low-power DRAM module used alongside the Vera CPU in Nvidia's next-generation Vera Rubin AI server platform, and its substrates command higher ASPs than conventional PCBs used in standard memory modules. TLB recently started developing SOCAMM3 substrates with two major domestic and overseas memory manufacturers, targeting mass production in 2028. The company also said some customers have agreed to reflect higher raw material costs in product prices in the fourth quarter, which is expected to contribute to earnings.
