Monolithic Power Surges on AI Demand, Lifts Growth Target to $6B

SCHAFFHAUSEN, Switzerland – April 30, 2026 – Monolithic Power Systems (MPS) today announced record-breaking first-quarter financial results that significantly surpassed Wall Street expectations, propelled by explosive demand from the artificial intelligence and data center sectors. The power semiconductor company posted a record quarterly revenue of $804.2 million, a 26.1% increase year-over-year, signaling its pivotal role in the global technology infrastructure buildout.

Investors reacted with strong approval, driving the company’s stock (MPWR) up over 6% in after-hours trading. The robust performance and an optimistic forecast for the second quarter prompted MPS to announce a dramatically increased capacity expansion goal, now targeting $6 billion, up from a previous $4 billion plan. This ambitious move underscores the company's confidence in its trajectory and its evolution from a component supplier to a full-service solutions provider.

“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, silicon-based solutions provider,” said Michael Hsing, CEO and founder of MPS, in the company's official release.

The AI Powerhouse

The engine behind the company's stellar quarter was its Enterprise Data division. Revenue from this segment, which provides critical power management solutions for AI and server applications, skyrocketed by an astonishing 97.7% year-over-year to $262.8 million. This segment alone accounted for nearly a third of the company's total revenue, highlighting the insatiable appetite for efficient power delivery in modern data centers. As AI models become larger and more complex, the demand for sophisticated, high-density power modules—a specialty of MPS—has intensified.

Complementing this growth, the Communications end market also saw a significant surge, with revenue climbing 33.1% sequentially and 55.5% year-over-year to $111.5 million. The company attributed this performance to strong sales of its power solutions for optical modules and switches, essential components for the high-speed networks that connect data centers.

Further cementing its position at the forefront of technology, MPS announced it has begun sampling its first high-speed interface products for DDR5 memory with major customers. The move into the rapidly expanding DDR5 Power Management IC (PMIC) market, which is critical for next-generation computing, positions MPS to capture another significant revenue stream as data centers and high-performance computers upgrade their memory infrastructure for improved speed and energy efficiency.

A Bold Bet on the Future

Beyond the impressive quarterly numbers, the most significant announcement was the upward revision of its capacity goal to $6 billion. This strategic decision is a clear indicator that MPS management foresees a long runway of sustained, high-level demand. The expansion is not merely about producing more chips; it involves advancing process technology from 60nm towards 40-45nm to achieve higher power density and investing in next-generation materials like silicon carbide (SiC) and gallium nitride (GaN) for high-voltage data center and low-voltage applications, respectively.

This strategic expansion aligns with a broader industry trend, where semiconductor companies are investing billions to meet the demands of the AI era. However, MPS's move is particularly notable for a fabless company, signaling deep confidence in its design prowess and its relationships with manufacturing partners.

The company’s forward guidance reinforces this optimistic outlook. For the second quarter of 2026, MPS forecasts revenue in the range of $890 million to $910 million, which would represent another record-setting period and suggests the momentum from the first quarter is not only continuing but accelerating. The non-GAAP diluted earnings per share of $5.10 for Q1 handily beat analyst consensus of $4.90, further bolstering investor confidence.

Navigating a Complex Global Stage

Monolithic Power Systems achieved these record results against a backdrop of what the company termed a “fluid geopolitical and macro-economic environment.” The global semiconductor industry continues to navigate challenges including US-China trade tensions, shifting tariffs, and a strategic realignment of global supply chains. For many industry players, making supply chains more resilient and geographically diverse has become the top strategic priority.

In this context, MPS’s performance is a testament to its diversified market strategy and its proactive supply chain management. The company has long emphasized a geographically diverse manufacturing footprint, both within and outside of China, which appears to be paying significant dividends by providing stability and adaptability. While the high-flying Enterprise Data and Communications segments powered growth, the company’s diversified portfolio showed varied results. The Automotive market posted modest growth of 5.1% year-over-year, while the Consumer and Industrial segments saw slight declines or slower growth, reflecting broader market softness in those areas.

This ability to capitalize on high-growth sectors like AI while weathering volatility in others underscores the success of its strategic model. The company's financial health remains robust, with cash, cash equivalents, and short-term investments growing to $1.37 billion. Operating cash flow was a strong $250.3 million for the quarter. While internal inventories increased, a look at inventory levels relative to the next quarter’s strong revenue forecast shows a decrease in days of inventory, suggesting efficient management and a company well-prepared to meet the surging demand it has forecasted.
