Monolithic Power Systems, Inc. (MPWR) Q2 2025 Earnings Call Transcript

Monolithic Power Systems (MPWR) reported record Q2 2025 revenue of $664.6 million, a 31% year-over-year increase, driven by broad-based growth across all end markets, notably initial shipments for new ASIC-based AI products. The company projects an 8% sequential revenue increase for Q3, with enterprise data growing 20-30%, and anticipates continued strong demand, albeit with short lead times. MPWR is strategically transforming into a full-service silicon-based solutions provider, expanding its total addressable market in enterprise data with 48V/800V systems, and expects significant contributions from its module business and eMotion solutions in the long term, positioning itself for continued outperformance in the analog sector.

Analysis

Monolithic Power Systems (MPWR) reported a record second quarter, with revenue reaching $664.6 million, representing a 31.0% year-over-year increase and beating expectations. The company issued strong guidance for the third quarter, projecting 8% sequential growth at the midpoint, driven by a significant 20-30% sequential increase in its pivotal Enterprise Data segment. This strength is underpinned by the commencement of initial shipments for new ASIC-based AI platforms, where management indicates MPS is emerging as a 'winner' with broad design-win activity across multiple large customers. Growth is diversified, with the automotive segment on track for 40-50% full-year growth and all other segments, except Storage and Compute, guided to grow in the high single digits for Q3. Management's caution on Storage and Compute stems from two exceptionally strong preceding quarters rather than observed demand weakness. Strategically, the company is managing short customer lead times and lean channel inventories, indicating shipments are aligned with real-time demand. Furthermore, MPS reiterated its capacity to support $4 billion in annual revenue and its progress in diversifying its supply chain, with 50% of capacity expected to be outside China by year-end, positioning it to capture future growth from next-generation 48V and 800V data center architectures, which represent upside to its current $4 billion enterprise data SAM.

Key Decisions for Investors

• Consider the accelerating momentum in the enterprise data segment, as the company is now shipping into new ASIC-based AI platforms and has guided for 20-30% sequential growth in Q3, solidifying its position as a key beneficiary of the AI infrastructure build-out.
• Evaluate the company's long-term growth potential beyond the current AI cycle, factoring in the strategic pivot to a higher-value solutions provider and significant TAM expansion opportunities from future 48V and 800V data center systems.
• Monitor booking patterns and management commentary on lead times, as the current environment of short-term ordering, while reflecting real demand, creates less forward visibility than in typical recovery cycles.
• Recognize the diversification of growth drivers, particularly the automotive segment's projected 40-50% full-year growth, which provides a robust, independent growth pillar alongside the data center business.
