Jmt

Founded in 1998, JMT is an EMS (electronic manufacturing services) specialist providing integrated production and delivery services using its own manufacturing facilities.

The company's primary revenue comes from OLED FPBA (flexible printed board assembly) products, with OLED-PBA supplied through Samsung Display for use in Apple iPad and related devices forming the core business.

According to an SK Securities report from March 2024, the estimated product mix showed Apple-facing OLED FPBA at 92.6%, LCD PBA at 4.5%, and other items at 2.9%, reflecting a structure heavily weighted toward Apple and OLED.

Production is carried out mainly through its Vietnam subsidiary, with TFT-LCD PBA and OLED panel FPBA for mobile phones as core product lines.

In its SMT (surface-mount technology) business, the company has pursued upfront investment in equipment such as chip mounters to secure competitiveness in productivity and yield management.

Within the supply chain, JMT purchases PCBs from Korea Circuit, performs SMT processing, and supplies the resulting PBA directly to Samsung Display—a structure that allows product-level, rather than simple processing-fee, revenue recognition.

Competitors in SMT within the Apple value chain include Korea Computer and Dreamtech, with SK Securities characterizing JMT as the most Apple-exposed 'pure play' among them in terms of Apple-facing SMT revenue share.

BH is also reported to be building PCB production lines as a potential future supplier, which could alter the competitive landscape.

JMT's consolidated revenue rose steadily over four years, from KRW 90.6bn in 2022 to KRW 122.7bn in 2023, KRW 164.0bn in 2024, and KRW 200.2bn in 2025.

Operating profit, however, showed sharp volatility separate from top-line growth: KRW 20.0bn (22.1% margin) in 2022, KRW 14.8bn (12.1%) in 2023, a steep drop to KRW 5.3bn (3.2%) in 2024, before recovering to KRW 13.1bn (6.6%) in 2025.

Net income attributable to owners followed a similar pattern, declining from KRW 29.4bn in 2022 to KRW 22.5bn in 2023 and KRW 8.9bn in 2024, before recovering to KRW 14.3bn in 2025.

Looking at the trailing four-quarter window (Q3 2025–Q2 2026), revenue rose from KRW 53.4bn in Q3 2025 to KRW 62.2bn in Q4 2025 and KRW 68.0bn in Q1 2026, before pulling back to KRW 60.7bn in Q2 2026.

Operating profit over the same period was solid at KRW 5.6bn in Q3 and KRW 6.1bn in Q4 2025, but declined to KRW 3.4bn in Q1 2026 and KRW 3.3bn in Q2 2026, indicating a clear quarterly margin slowdown.

Net income to owners also peaked at KRW 6.5bn in Q3 2025 before gradually narrowing to KRW 5.8bn, KRW 4.7bn, and KRW 3.3bn in the following three quarters.

On the cash-flow side, operating cash flow briefly turned negative at KRW -3.9bn in 2024 before recovering to KRW 17.3bn in 2025, signaling improved financial stability. The debt ratio, however, climbed steadily from 33.6% in 2022 to 46.8% in 2025, reflecting rising leverage alongside growth-related investment.

JMT's performance is closely tied to the pace of Apple's OLED adoption. According to an August 2026 ZDNet Korea report, Apple plans to extend OLED displays sequentially over the coming years to the iPad mini (2026), MacBook Pro (H2 2026 or early 2027), iPad Air (2027), and iMac/MacBook Air (2028–2029).

This represents an expansion of OLED beyond the existing iPhone and iPad Pro base into the full tablet and notebook lineup, a shift that could affect demand structure across the PBA and SMT supply chain.

On the supply side, Samsung Display announced in April 2023 a plan to invest KRW 4.1 trillion in an 8.6-generation IT-OLED line targeting mass production in 2026, and the timing and yield of this line are expected to influence volume allocation among downstream component and assembly makers.

Competitively, a division of labor has formed in which Korea Circuit supplies PCBs that JMT and Korea Computer purchase, process via SMT, and supply directly as PBA to Samsung Display, while BH—traditionally an FPCB specialist—is reportedly building PCB lines to enter this market, a development that could intensify competition.

Because the tablet and notebook end markets tend to grow more slowly than smartphones, the shift to OLED may act more as a driver of profitability improvement through product mix than of overall volume expansion.

Overall, JMT's results are heavily influenced by a specific supply channel—the Apple–Samsung Display chain—making a single customer's product roadmap and volume allocation a more decisive industry variable than broader cyclical swings.

The company's future earnings trajectory is likely to depend heavily on Apple's OLED expansion roadmap and the ramp timing of Samsung Display's IT-OLED production capacity.

With the iPad mini's OLED conversion reportedly slated for 2026, the timing of the new model launch and the pace of initial volume ramp-up could directly affect results over the coming quarters.

That said, the renewed decline in operating margin during the first half of 2026 suggests that initial yield and cost burdens during product-line transitions, or shifts in customer order timing, remain variables.

An SK Securities report from March 2024 suggested that additional operating profit contribution could emerge in 2025–2026 as Apple's OLED adoption extends to standard iPad models, but as this view is now more than two years old, it should not be read as a current guidance.

The MacBook Pro's expected OLED transition in H2 2026 or early 2027 could represent a mid-term product diversification opportunity, though no specific confirmed order has been disclosed in available materials.

The rise in the debt ratio and the temporary deterioration in operating cash flow in 2024 indicate that investment and inventory burdens tied to new-line preparation could continue to affect earnings stability.

Overall, the key watch points ahead are whether quarterly margins recover and whether Apple and Samsung Display order schedules become more concrete.
