📉 Samsung Electro-Mechanics: AI Substrate Expansion and the Diverging MLCC Supply Chain - 2026.09.12
Hi, it’s Peanuts. The key issue for Samsung Electro-Mechanics is how quickly it can expand AI substrates and who will capture the gaps in the MLCC supply chain. As AI chips grow larger, ‘bridge’ technology in package substrates is drawing attention, and Samsung Electro-Mechanics has been introduced as a company entering the large-area substrate race [1]. At the same time, its focus on high-value products is creating room for competition in other markets. Is it really enough to look only at the growth drivers?
AI Substrates: Bridges Become a New Verification Point
According to reports, bridge technology is gaining prominence in semiconductor package substrates as AI chips become larger. Samsung Electro-Mechanics was mentioned, along with LG Innotek, as a company competing in large-area substrates [1], while a separate report said it had unveiled a 2.5D package substrate that places a silicon interposer on the substrate. This technology connects the GPU and HBM through fine wiring, and Samsung Electro-Mechanics is targeting mass production in 2027 [2].
What matters here is not the exhibition or technology disclosure itself, but the timeline leading to mass production and whether actual customers adopt it. Even impressive technology has a separate stage before it translates into revenue. A bridge may look sturdy, but traffic must be confirmed before its value can be recalculated. Peanuts sees this as the gap between ‘technology disclosure’ and ‘monetization validation.’
MLCCs: Look at the Other Side of High-Value Concentration Too ⚠️
Reports have also said that while Samsung Electro-Mechanics focuses on AI MLCCs, Chinese companies are attempting to enter the global PC supply chain [3]. Related coverage said leading companies such as Samsung Electro-Mechanics and Murata are concentrating production capacity on high-value MLCCs for AI servers, creating a supply gap in general-purpose MLCCs that Chinese companies are trying to exploit [4].
This is different from simply saying that AI demand is strong. Even if the share of high-value products rises, a shift in competition among general-purpose products can cause pricing and volume conditions to diverge by product category. There is a structural gap that cannot be summarized by saying, ‘The overall MLCC market is good.’ Is that really the case? Whether competitive pressure in general-purpose PCs is also increasing as demand for AI servers grows remains a variable that could determine the possibility of a value trap.
Separate Supply Shortage Forecasts from Confirmed Company Facts
Content from Korea Economic TV explained that MLCC demand is growing as AI data centers and the ESS market expand, while concerns over shortages are increasing as Murata concentrates production capacity on high-value products for AI servers and automotive applications rather than general-purpose products [6]. However, this content conveys a third party’s outlook and concerns, so there is no basis for interpreting it as confirmation of Samsung Electro-Mechanics’ supply situation or earnings improvement.
From a fundamental perspective, product mix, whether supply gaps persist, and the speed of Chinese companies’ entry must be considered separately rather than focusing only on demand growth. Even in short- to medium-term swings, if these three factors move in different directions, the story and the numbers may diverge.
Has the Stock Price Reflected Expectations First? 📉
There was a report that Samsung Electro-Mechanics’ stock price recovered and closed around the ₩1,400,000 level in the second week of September [5]. Recent price movements may be interpreted as reflecting expectations for AI substrates and MLCCs, but the price level alone does not confirm business performance.
There is still time before the large-area substrate target of mass production in 2027, while MLCCs are seeing both a focus on high-value products and intensifying competition in the general-purpose market. Rather than being optimistic about Samsung Electro-Mechanics based solely on technological expansion, Peanuts believes it should be assessed by the speed at which technology disclosures translate into actual revenue and profit. One question remains: Which will show up in the numbers first—the progress toward mass production of AI substrates or changes in the general-purpose MLCC supply chain?
