DIODES Incorporated Announces Global Price Adjustments Effective April 1, 2026

PLANO, Texas – March 20, 2026 – Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application-specific standard products in the broad discrete, logic, analog, and mixed-signal semiconductor markets, today announced a strategic price adjustment across select product lines. The price increase, ranging from 8% to 15%, will take effect on April 1, 2026, and applies to all new orders received on or after this date, as well as existing backlog for affected components.

This decision follows a comprehensive review of the company’s operational costs and market dynamics, which have been significantly impacted by persistent inflationary pressures throughout the global semiconductor supply chain.

Key Drivers Behind the Price Adjustment

Diodes cited several critical factors that have necessitated this price action, despite ongoing efforts to mitigate cost increases internally:

1. Escalating Raw Material Costs: The prices of core semiconductor materials, including silicon wafers, precious metals (gold, silver, copper), and specialty chemicals, have surged by over 35% year-over-year. This is driven by global supply shortages, geopolitical tensions affecting key mining and production regions, and robust demand from the AI and automotive sectors.
2. Soaring Logistics and Energy Expenses: International shipping costs have risen by nearly 50%, while energy prices for manufacturing facilities have continued their upward trajectory, further compressing margins.
3. Increased Labor and Operational Costs: To attract and retain skilled talent in a competitive market and maintain high production standards, Diodes has implemented wage and benefit increases, adding to operational overhead.
4. Strong Market Demand and Capacity Constraints: The global semiconductor industry is experiencing a significant upswing, fueled by explosive growth in AI computing, electric vehicles (EVs), industrial automation, and IoT devices. This surge in demand has led to tight capacity across mature wafer fabrication nodes (8-inch and 6-inch), which are critical for Diodes’ product portfolio.

Impact on Customers and Market Context

The price adjustment is part of a broader industry trend, with numerous semiconductor manufacturers, including Infineon, TI, and Nexperia, having recently announced similar measures to address cost pressures and ensure supply chain stability. Diodes emphasized that this move is essential to safeguard its ability to invest in R&D, maintain production capacity, and continue delivering the high-quality, reliable components that its global customer base depends on.

“While we deeply regret the impact this will have on our valued partners, this price adjustment is a necessary step to ensure the long-term health of our operations and our ability to support your success,” stated Emily Yang, Senior Vice President of Worldwide Sales and Marketing at Diodes. “Our sales and distribution teams are ready to work closely with each customer to provide detailed information on affected part numbers and assist with a smooth transition.”

Diodes reassured customers that orders placed and confirmed prior to April 1, 2026, will be fulfilled at the original contracted prices. The company remains committed to optimizing its manufacturing processes and exploring efficiencies to minimize future cost impacts.
