StockStory’s Take

Monolithic Power Systems delivered revenue above Wall Street’s expectations for Q1, with management highlighting the impact of broad-based demand across storage, computing, and automotive segments. CEO Michael Hsing attributed the quarter’s results to strong design win momentum, especially in enterprise data and automotive, and emphasized the company’s ongoing transformation from a chip supplier to a full-service silicon solutions provider. CFO Bernie Blegen also noted the positive contribution of new product ramps and an improved operating margin compared to last year.

Looking ahead, management pointed to continued investment in technology and supply chain diversification as key drivers for the rest of the year. Michael Hsing described growing confidence in the second half due to a backlog of design wins, particularly in enterprise data and automotive, but acknowledged some uncertainty in the timing and magnitude of customer ramps. The company expects revenue for the next quarter to remain steady, with margins influenced by product mix and ongoing supply chain adjustments.

Key Insights from Management’s Remarks

Management emphasized that the company’s diversified strategy and design wins were central to Q1’s performance and set the stage for future growth across several end markets.

• Enterprise Data Momentum: Management cited broad-based design wins and ramping qualifications with major customers, positioning the company for increased enterprise data revenue later this year. Michael Hsing stated that while visibility is improving, the major ramps are expected in the second half.
• Automotive Content Expansion: The automotive business posted its third consecutive quarter of double-digit sequential growth. Management credited this to increased content per vehicle, particularly from new power management modules supporting next-generation vehicle platforms in North America and Europe.
• Storage & Computing Upswing: Segment revenue increased sharply due to both memory and notebook demand. Management said growth was balanced across memory types (like DDR5) and end-user devices, and that results were driven by design wins rather than inventory build-up.
• Supply Chain Diversification: The company’s multi-year effort to localize manufacturing and R&D across regions has improved resilience to tariffs and geopolitical risks. Hsing explained that post-pandemic capacity expansions outside China now support both China and global customers.
• Transformation to Solutions Provider: Management reiterated its strategy of evolving from a chip-only supplier to a provider of complete silicon-based solutions, including system-level modules for building automation and medical devices. Early customer engagement on these new products was described as encouraging for long-term growth.

Drivers of Future Performance

Management expects steady performance in the upcoming quarter, with future growth dependent on new product qualifications, customer ramps, and continued diversification across end markets.

• Design Win Ramps: Many recent design wins in enterprise data and automotive are expected to translate into higher revenue later in the year, though the precise timing of customer adoption remains uncertain.
• Product Mix and Margins: Future margins will be affected by the mix of new versus mature products. Management aims to maintain margins within historical ranges, despite pressure from high-volume, lower-margin products.
• Supply Chain and Tariffs: Ongoing efforts to diversify manufacturing and R&D are intended to reduce exposure to tariffs and supply interruptions, but shifts in global trade policy or customer behavior could still introduce risks.

Top Analyst Questions

• Tore Svanberg (Stifel): Asked if the current quarter marks a low point for enterprise data and how supply chain diversification is impacting competitiveness; management indicated improved confidence and highlighted the benefits of local manufacturing outside China.
• Quinn Bolton (Needham): Sought details on the narrowing of enterprise data outlook and the impact of a customer’s platform change; management maintained a wide forecast range but expressed confidence due to recent product qualifications.
• Ross Seymore (Deutsche Bank): Questioned potential segment volatility and customer order behavior related to tariffs; management reported consistent demand and minimal pull-in/push-out effects.
• Rick Schafer (Oppenheimer): Inquired about timing for significant rack power solution revenue and automotive content drivers; management expects material rack power revenue in 2026 and noted automotive growth is content-driven across multiple regions.
• William Stein (Truist): Asked about direct tariff impacts and the long-term shift to full-system solutions; management said tariffs are not directly affecting unit costs and described positive customer response to new system-level products.
