Delta Electronics Thailand Flags Semiconductor Squeeze and Surprise EU Sanctions as AI Demand Outstrips Supply Chain
Q2 2026 earnings call, July 26, 2026
Delta Electronics Thailand posted another blowout top line in the second quarter, with revenue reaching $2.011 billion, up 50.7% year-over-year and 3.4% sequentially. But the headline growth masked a sharper story underneath: net profit of $186 million was up 33.4% year-over-year yet fell 35% quarter-over-quarter, as a tightening raw material market and an unexpected European Union sanctions action against a Chinese semiconductor supplier forced the company to scramble for alternate sourcing and eat into margins.
Raw Material Squeeze Turns Structural, Not Transitory
CEO Victor Cheng was direct about the source of margin compression, telling analysts that the cost pressure has broadened well beyond the usual AI-related components. "IC fabrication costs are going up and DRAM prices have gone up substantially. This trend has percolated to other segments, PCB, Power MOSFET, MLCC, some of these precision cast components, metal parts, even chemical raw materials," Cheng said. The mechanism is a classic supply reallocation problem: AI and data center customers are commanding priority access to constrained semiconductor and passive component supply, starving other segments and pushing up prices across the board. Middle East conflict-driven petroleum cost inflation is compounding the pressure on plastics and chemical inputs.
Management does not expect meaningful relief until the fourth quarter, when Delta enters its annual pricing negotiation cycle with both suppliers and customers. Cheng was candid that passing through costs will not be quick or easy: "Nobody is that easy or willing to accept price increase... we do believe that we have very justifiable causes to ask for a price increase. It's just various customers will take different length of time to achieve that goal." Investors should treat gross margin normalization as a fourth-quarter-into-2027 event, not a near-term fix.
Surprise EU Sanctions on Chinese Supplier Disrupted AI Shipments
The most notable disclosure on the call was a supply chain shock investors likely had not previously priced in. In April 2026, the European Union sanctioned a Chinese semiconductor company, Yanxi, with immediate effect, cutting Delta off from a specific diode and semiconductor source with no warning. Cheng described the scramble that followed: "The order took effect almost immediately, which caught us by surprise, and then we were constrained to find a second source quickly in order to make the shipment. This did affect some of the AI and Data Center customer deliveries." This follows a similar disruption last year from the US-Netherlands-China export control dispute. While Cheng said the situation "has eased toward Q3," he flagged a "lingering effect," underscoring that geopolitical sanctions risk is now a recurring, rather than one-off, operational variable for Delta's AI-linked supply chain.
Inventory Provisions and Hub Model Exposure
Delta booked a THB 800 million inventory provision in the quarter, tied largely to its hub-based delivery model with North American customers, where product is shipped into regional hubs and revenue is only recognized as customers draw down inventory. Cheng explained that some customers themselves were constrained by DRAM and other component shortages, delaying their ability to integrate finished systems, which slowed hub drawdowns and forced higher provisioning on slower-moving material and finished goods. Management expects this to improve by the third quarter or, at the latest, early in the fourth quarter, but it is a reminder that even amid record AI demand, downstream integration bottlenecks at customers can directly hit Delta's reported profitability.
Tariff Pass-Through Creates a Coming Revenue Headwind
Delta disclosed it has recorded just over $100 million in US import tariffs paid on behalf of customers, which will be refunded to Delta and then passed back to those customers. Cheng flagged that this creates a mechanical revenue reduction in the "next quarter or two" as the refunded tariff flows back out through lower top line, a detail investors will want to strip out when assessing underlying revenue growth in coming quarters. Separately, management said the current US tariff rate of 12.5% is roughly in line with regional peers and does not impair Thailand's relative competitiveness, since most tariff costs are already contractually borne by customers.
Segment Momentum: Data Center Strength, but Timing Volatility
Underlying demand trends remain robust. Industrial Automation revenue rose 23% quarter-over-quarter and 29% year-over-year, powered by PCB and AI server assembly activity in Thailand and Vietnam. Energy Infrastructure first-half revenue was up 121% year-over-year on integrated grid and renewable energy demand. Data center revenue jumped 79% quarter-over-quarter but was still down slightly year-over-year, which management attributed to "major customer projects being postponed to the second half of 2026," rather than any demand destruction, with the pipeline described as "healthy." Australia stood out as the fastest-growing sub-region, with revenue up 144% quarter-over-quarter and 287% year-over-year, driven by AI cooling products, while its energy infrastructure business there grew roughly 500% quarter-over-quarter on microgrid demand. India grew more modestly, up 2.5% quarter-over-quarter, with management citing pricing pressure, currency volatility and battery supply constraints as ongoing headwinds.
Full-Year Guidance and Capital Allocation Signals
Delta declined to give a specific full-year revenue number but reiterated a double-digit growth target for 2026, with Cheng stating the company will "aim for our double-digit revenue growth without any issues" based on order visibility extending roughly six months out via customer rolling forecasts. R&D spending rose 88% year-over-year but management said this is tracking to a targeted 3% to 3.5% of operating revenue, currently sitting at 3% to 3.1%, suggesting the R&D ramp is intentional and will not run away as a margin drag. Delta also opened a new R&D center in Soest, Germany in May 2026 to localize power solution development for AI, high-performance computing and electric mobility applications in the EMEA region, and management expects Delta Thailand's contribution to overall group revenue to rise modestly from roughly one-third currently to a 30% to 40% range over the next few years.
On the macro backdrop, management pointed to the IMF's July 2026 update naming Thailand among the world's top four net exporters of AI hardware, alongside Taiwan, South Korea and Malaysia, and to the establishment of Thailand's National Semiconductor Board in June 2026, targeting THB 2.5 trillion in investment to build domestic chip capability by 2050. These policy tailwinds support the structural bull case for Delta's manufacturing footprint, even as the near-term story is dominated by margin pressure from the very AI supply chain tightness that is driving its growth.
