Ongoing Business Conditions

In the second quarter of 2026, MPS achieved record quarterly revenue of $980.6 million, 21.9% higher than the first quarter of 2026 and 47.6% higher than revenue in the second quarter of 2025.

Our quarterly performance was the result of our continued innovation, our consistent execution and the resilience of our diversified market and supply chain strategy.

Q2 2026 highlights include:

•All end markets grew sequentially with Enterprise Data growing 45% as we continued to see strong, broad-based ordering patterns.

•We extended our capacity goal significantly beyond $6B to support future revenue growth and our transformation into a full solution provider.

•We received initial orders for high-speed DDR5 memory components which we expect to grow our SAM into next year.

•We began sampling High Voltage AC to DC products for 800V data center architectures as we expand beyond our current AI and server core power solutions.

•In our Automotive market, so far this year, we have shipped products for over 1500 new sockets as we increase our footprint in both ADAS and other applications within the vehicle.

We continue to adjust to the fluid geopolitical and macro-economic environment, but our diversified market strategy remains unchanged:

•MPS focuses on innovation and solving our customers’ most challenging problems.

•We consistently invest in new technologies that open new end markets and applications.

•We continuously expand and diversify our global supply chain allowing us to capture future growth opportunities, maintain supply stability, and rapidly adapt to market changes as they occur.

“Our results demonstrate the strength of our diversified model and our continued success in transforming from a chip-only, semiconductor supplier to a full service solutions provider,” said Michael Hsing, CEO and founder of MPS.
