MLCC distributor inventory drops 8% to record low on AI demand

Global MLCC distributor inventory fell to a record low in early August even as unit prices kept climbing, a divergence UBS says will spread from AI channels to the broader market.

Global multilayer ceramic capacitor (MLCC) distributor inventory fell 8% in the four weeks to Aug. 9 to a record low, while the unit price index climbed 7%, as AI-server demand outpaces supply across the passive-components market.

UBS Evidence Lab, the research arm tracking more than 100 distributors worldwide, published the data. The bank expects the supply-demand tightening to originate from AI-related demand and distributor channels before spreading to the broader market.

Year over year, distributor inventory volume was down 22% at the end of July, while inventory value rose 6% and the unit price index gained 13%, approaching its highest level since January 2023. Among major manufacturers, Samsung Electro-Mechanics posted the steepest inventory decline at 20% and the largest unit price increase at 14%, while Taiyo Yuden's inventory value jumped 32% on a 13% price gain.

UBS maintained Buy ratings on Samsung Electro-Mechanics, Murata Manufacturing and TDK, and a Neutral rating on Taiyo Yuden. The five manufacturers trade at 2026 estimated price-to-earnings ratios of 15.7x to 65.5x, with Samsung Electro-Mechanics carrying the largest premium on its AI-server exposure.

Volume Falls, Prices Rise Across the Board

The divergence between shipment volumes and prices is widening at nearly every major producer. As of Aug. 9 versus four weeks earlier, Murata Manufacturing's inventory volume fell 8% while its inventory value rose 8% and unit price index gained 6%. TDK's inventory dropped 7% with value up 3% and prices up 8%. Taiwan's Yageo slipped 1% in volume but added 13% in value and 7% in price. Taiyo Yuden held volume flat while value surged 32% and prices rose 13%.

Samsung Electro-Mechanics stands out: its 20% inventory decline came with a 4% drop in inventory value but a 14% gain in unit prices, underscoring pricing power in a shrinking-volume environment. The pattern reflects differences in product mix, with higher-end MLCCs used in AI servers and data centers commanding the steepest price increases.

Measured against the previous inventory cycle trough, the price support is even clearer. Inventory value indices are up 19% at Murata, 29% at Samsung Electro-Mechanics, 45% at Yageo, 3% at TDK and 81% at Taiyo Yuden. Taiyo Yuden's inventory volume sits roughly 15% above its recent bottom, the highest positioning among the five.

Book-to-Bill and Utilization Point to Tighter Supply

Two Japanese MLCC makers explicitly flagged in their April-June quarterly reports that distributor demand showed signs of overheating and said they may raise prices to correct the imbalance. UBS acknowledged some distributor orders may include pull-forward buying, but said the rapid decline in inventory is an objective fact.

The transmission path is visible in operating metrics. Murata's April-June book-to-bill ratio stood at 1.47 and Taiyo Yuden's at 1.72, both above 1, meaning orders continue to outstrip shipments. Both companies guided to 95% capacity utilization for July-September, leaving little room for near-term production increases, and both raised AI-related sales guidance. A ratio above 1 combined with near-full utilization provides fundamental support for further price appreciation.

For investors, the MLCC cycle reversal is at a critical juncture. Sustained inventory drawdowns alongside rising unit prices indicate end-market demand, particularly from AI servers, data centers and high-end consumer electronics, is absorbing supply-chain stock. If the trend holds, gross margins and revenue growth at Samsung Electro-Mechanics, Murata, TDK and Yageo could strengthen further in the second half. UBS's targets imply upside for the Buy-rated names, with Samsung Electro-Mechanics at 2.5 million won (about $1,800), Murata at 13,200 yen ($83) and TDK at 4,950 yen ($31), while Taiyo Yuden's Neutral rating carries a 17,700-yen ($110) target.
