Monolithic Power Systems Reports Record Q1 Revenue: A Strong Start to FY2026

Monolithic Power Systems [MPWR] delivered a strong start to FY2026, with Q1 revenue of $804.2 million, a 2.8% beat over the street estimate of $781.9 million. This marks a 7.1% sequential increase from Q4 FY2025 and a 26.1% year-over-year growth, per CEO Tony Balow: "In Q1, MPS achieved record quarterly revenue of $804 million, 7% higher than the fourth quarter of 2025 and 26% higher than the first quarter of 2025." The company's EPS of $5.10 also exceeded the street estimate of $4.90, representing a 4.1% surprise.

Despite the revenue growth, Monolithic Power Systems maintained its gross margin at 55.3%, consistent with the company's guidance. CEO Tony Balow noted, "For the last 4 quarters, we've been flat at 55.5%, which is at the low end of our gross margin model for growth, which ranges 55 -- mid-50s to upper 50s." This stability in gross margin is a testament to the company's efficient cost management and pricing strategies.

The company is also making significant strides in capacity expansion. CEO Tony Balow highlighted, "We sampled our first high-speed interface products for DDR5 at major customers and MPS continued to grow our capacity past our original $4 billion plan with a new goal of reaching $6 billion in the near future." This expansion is geographically diverse, both inside and outside of China, as CFO Michael R. Hsing emphasized: "For the $6 billion goal for manufacturing pipeline."

Monolithic Power Systems saw particularly strong growth in its communications end market, which grew 33% sequentially. The company also noted continued strength in HDD and SSD markets: "We see strength in HDD and SDD continue out of last year and into Q1."

The company's focus on high-speed interface products for DDR5 is another key driver of growth. CEO Tony Balow stated, "And we see strength in DDR5." This aligns with the broader industry trend towards higher data rates and more efficient power solutions, positioning Monolithic Power Systems well for future growth.

Monolithic Power Systems is maintaining a confident outlook for the future. CEO Tony Balow raised the company's growth floor from 50% to 85% year-over-year: "So at this point in time, I think we're comfortable raising that floor up to around 85% year-over-year growth." This increased guidance reflects the company's belief in the strength of its design wins and the potential for these to turn into significant revenue streams.

CFO Michael R. Hsing echoed this sentiment, stating, "We -- clearly, and we have -- we see our near future, we see a lot more activities, a lot potentials and all these design wins is imminent, they will turn into revenues." The company is also optimistic about its new products and capacity expansions, which are expected to drive growth over the next 2 to 3 years: "And these ones will pave the way for our next 2 to 3 years out to remain on the same growth trajectory."

Monolithic Power Systems' strong performance is supported by its relationships with key customers and suppliers. The company's DC-DC converters for GPU power delivery are particularly important for [NVIDIA (NVDA)], a major customer in the data center and high-performance computing markets. CEO Tony Balow noted, "Yes, I just think the last thing I'd add, just so it's really clear is nothing about our outlook or anything we said about enterprise data floors because we see any constraints in the supply chain."

The company's strategic capacity expansion and product diversification are designed to mitigate supply chain risks and ensure consistent delivery to customers. CFO Michael R. Hsing highlighted the company's readiness for high-voltage applications: "And we just have our -- for that application is ready, and also have 800 volts, go to 10,000 volts, okay?"

Monolithic Power Systems' performance stands out when compared to its peers in the fabless semiconductor industry. While many peers are seeing strong revenue growth, Monolithic Power Systems' 26.1% year-over-year revenue growth is particularly noteworthy. For example, [NVIDIA (NVDA)] reported a revenue of $81.61 billion with a 85.2% year-over-year growth, and [GOOGL] reported a revenue of $109.90 billion with a 21.8% year-over-year growth. Monolithic Power Systems' gross margin of 55.3% is also competitive, falling within the mid-50s to upper 50s range, which is consistent with its guidance.
