Samsung Electro-Mechanics has signed an 879.3 billion won supply contract for multilayer ceramic capacitors, or MLCCs, with a customer it names only as a large global company, according to a filing on Korea’s DART disclosure system on 30 October. The filing states the amount as $658 million. By our arithmetic, the order equals about 23% of the 3.76 trillion won of revenue the company reported for the third quarter.
Seoul Economic Daily reported that the capacitors are for AI servers, and that the company’s orders this year have “topped 5 trillion won for the first time”. By our count of the company’s DART filings, eight supply contracts signed in 2026 add up to about 5.19 trillion won, or 45.9% of its 2025 revenue.
Short explainer · Samsung Electro-Mechanics’ $658M order

Business Pill · Lead Time
A short explainer on lead time: why the wait is part of the price. It teaches the general idea only and says nothing about any company in this piece.
The key insight: By our arithmetic, Samsung Electro-Mechanics’ 879.3 billion won MLCC order equals about 23% of its preliminary third-quarter revenue, and its eight supply contracts filed on DART in 2026 total about 5.19 trillion won, or 45.9% of its 2025 revenue.
The contract runs from 21 December 2026 to 21 December 2027, the filing says. It was signed on 29 October, carries no down payment, and is worth 7.8% of the company’s 2025 consolidated revenue of 11.31 trillion won.
The buyer’s name and the main terms are withheld until 21 December 2027 at the buyer’s request, the filing says. It adds that the amount and the period may change in the course of business.
Seoul Economic Daily reported that Samsung Electro-Mechanics said the capacitors are for “AI servers and related devices made by the client”. The newspaper called it the sixth long-term agreement for MLCCs this year and the second largest on record, after a 1.07 trillion won contract.
Cumulative value of the eight supply contracts Samsung Electro-Mechanics filed on DART in 2026, by contract date, in trillion won: 5.19 trillion won after the 879.3 billion won MLCC order of 29 October, equal to 45.9% of 2025 revenue by our arithmetic. The May jump is a 1.56 trillion won silicon capacitor contract. Source: DART filings, May to October 2026.
Eight Contracts in Six Months
DART lists eight supply contracts from Samsung Electro-Mechanics between 20 May and 29 October 2026. Six are for MLCCs, one counting inductors as well; one is for silicon capacitors and one for package substrates.
By our arithmetic, the six MLCC contracts total about 3.27 trillion won, or about $2.35 billion at the dollar amounts in the filings, equal to 28.9% of 2025 revenue. The largest was 1.07 trillion won, signed on 31 August; the 879.3 billion won order is the second largest.
The biggest single contract this year was not for MLCCs. A 1.56 trillion won silicon capacitor contract signed on 20 May, 13.8% of 2025 revenue, runs to the end of 2028; the other seven run through 2027.
October alone brought three contracts: MLCCs on 6 and 29 October and package substrates on 18 October. By our arithmetic they total about 1.53 trillion won, or about $1.14 billion, equal to 13.5% of 2025 revenue.
The Quarter Behind It
Samsung Electro-Mechanics’ preliminary third-quarter revenue was 3.76 trillion won, up 30.3% from a year earlier, and operating profit was 691.0 billion won, up 165.5%, according to its DART filing of 28 October. The figures are preliminary and unaudited.
Seoul Economic Daily reported that the company’s component production lines ran at 91% utilisation at the end of the first half, and that it is building a third MLCC plant in Calamba, in the Philippines, targeting operation in the first quarter of next year.
Murata, Ibiden and the Capacitor Squeeze
On the same day, Murata said it plans about 1 trillion yen of MLCC capacity investment over five years, about $6.3 billion by our arithmetic in that piece. A day earlier Ibiden approved about 151 billion yen for new substrate capacity, as we reported. Those are investment plans; the Samsung Electro-Mechanics figures are customer orders, so we do not add them together.
In September the company approved 4.27 trillion won, about $3.14 billion, for FC-BGA substrate capacity at Sejong, as the Korea Times reported. On 26 October we reported that some of its MLCCs carried a 61-week standard lead time at DigiKey, against 17 weeks for Murata by iM Securities’ comparison, as Newspim reported.
The Structural Read
As we read the filings, most of this year’s contracts are for delivery in 2027: seven run through 2027 and the silicon capacitor contract runs to the end of 2028, so the orders mostly describe next year’s sales.
By our arithmetic, the six MLCC contracts alone total about 3.27 trillion won, or 28.9% of 2025 revenue, and the 879.3 billion won order is the second largest of them after the 1.07 trillion won contract signed on 31 August.
As we read the filings, every buyer is withheld: each contract names its counterparty only as a large global company, and the 30 October filing keeps the name and main terms back until 21 December 2027 at the buyer’s request.
A Samsung Electro-Mechanics official, as reported by Seoul Economic Daily, 30 October 2026
“Demand for high-performance, high-reliability MLCCs is expanding along with the growth of the AI industry”
Three Implications
FOR AI SERVER MAKERS Seoul Economic Daily reported that the capacitors in the 30 October contract are for AI servers and related devices made by the client, with deliveries from 21 December 2026 to 21 December 2027 under the filing.
FOR SAMSUNG ELECTRO-MECHANICS’ FINANCES Its preliminary third-quarter revenue rose 30.3% to 3.76 trillion won and operating profit rose 165.5% to 691.0 billion won, according to its DART filing of 28 October.
FOR RIVAL CAPACITOR MAKERS On the same day Murata said it plans about 1 trillion yen of MLCC capacity investment over five years; our 26 October piece reported a 61-week DigiKey lead time for some Samsung Electro-Mechanics MLCCs against 17 weeks for Murata, by iM Securities’ comparison.
The analysis puts it this way: “This entire ecosystem has been shaped by constraints, bottlenecks, chokepoints, and scarcity at every layer.”
As we read it, the contracts show one of those constraints being priced in advance: buyers are signing for capacitors to be delivered through 2027, according to the filings. The analysis does not discuss Samsung Electro-Mechanics or its October 2026 contracts.
What Is Not Established
The filings do not name the buyers, the products’ prices or how much of each order is for AI servers; the AI-server use comes from the company’s statement as Seoul Economic Daily reported it. Seoul Economic Daily’s 5.18 trillion won total and its count of about 50 companies with which the company has signed or is negotiating long-term agreements are the newspaper’s figures. Our totals cover the eight 2026 contracts listed on DART and are our arithmetic.
This Week In The AI Supercycle
Execution Fault Lines, Concentrated Demand, and Geopolitical Firewalls
This week’s issue: the AI build is not short of demand for its parts. It is short of cheap money, and its end revenue rests on a narrow base of large, often venture-funded buyers.
Samsung Electro-Mechanics’ 879.3 billion won MLCC order equals about 23% of its preliminary third-quarter revenue, by our arithmetic, and is the second largest of six MLCC contracts it has filed this year. By our count, its eight 2026 supply contracts total about 5.19 trillion won, 45.9% of its 2025 revenue, with deliveries running through 2027 and, for one contract, 2028.
A note on sourcing. The contract amounts, periods, shares of revenue and the withheld buyer come from Samsung Electro-Mechanics’ single sales and supply contract filings on Korea’s DART system, and the third-quarter figures from its preliminary results filing of 28 October 2026. The AI-server use, the order milestones, utilisation and plant details are as Seoul Economic Daily reported them. The totals and ratios are our arithmetic. We did not contact Samsung Electro-Mechanics.
