Quarterly Highlights
The upward revision of the Enterprise Data YoY growth floor from 130% to 150% is the most significant single signal this quarter.
First-ever US$1B Quarterly Revenue Milestone: 2026 Q3 revenue reached approximately US$1.2B, up 22% QoQ and 63% YoY (vs. 2025 Q3), about 3.6% above the pre-earnings market expectation of ~US$1.16B. Based on the first three quarters plus the midpoint of Q4 guidance, fiscal 2026 revenue would grow about 55% YoY (the company gave no full-year guidance), which management describes as an "explosive growth period."
Enterprise Data YoY Guidance Floor Significantly Raised: CFO Tony Balow (Note: Source text says Tony Balow; context specifies Tony Balow) clearly announced that the full-year YoY growth floor for Enterprise Data has been raised from 130% to 150%, 20 percentage points higher than last quarter's guidance. Momentum stems from a rapid increase in ASIC customers, rising module penetration, and increased power content per server from new platforms.
Communications Business Grows 43% QoQ, Becoming the Second Fastest Growing End Market: The Communications segment grew approximately 43% this quarter, driven by the dual engines of optical modules and switch business. CFO Tony Balow noted that while optical modules have a long growth runway, the switch business joined earlier this year; the combined effect became apparent in Q3, making Communications the second fastest-growing market after Enterprise Data for the year.
Capacity Surpasses US$6B Annualized Support Level, Path to US$8B Announced: Capacity has exceeded the annualized support level of US$6B in revenue. Management further announced plans to expand capacity to US$8B by the second half of 2027, with a long-term goal of US$10B. Using a fabless model, this expansion does not require a massive increase in CapEx; CFO Tony Balow stated that no major changes to the capital structure are expected.
Automotive Segment Launches Mass Production in Q3, Receives First 48V Orders: The Automotive division began mass production this quarter and received its first orders for 48V power solutions. Management stated that design wins for 48V and zonal architecture will be growth drivers for 2027, with demand geographically diversified across the US, Europe, and China.
Industrial and Robotics Business Shows Strong QoQ Growth, Design Wins Accumulating: The Industrial segment saw broad growth this quarter, with robotics solutions (including sensors and motor control products) starting mass production in multiple regions. Founder and CEO Michael Hsing stated that the robotics business is still in its very early stages; as AI vision technology improves, future revenue will be significantly higher than current levels.
Gross Margin Expands Steadily, Non-GAAP Operating Profit Margin Improving ~1 Percentage Point per Quarter: Non-GAAP gross margin was 55.7%, up 10 basis points QoQ; GAAP gross margin was 55.4%, up 20 basis points QoQ. Q4 guidance midpoint predicts another ~10 bps increase, staying within the 55%~60% target range. CFO Tony Balow noted that the recent non-GAAP operating margin improvement of nearly 1 percentage point per quarter shows significant operating leverage during high-speed growth.
Over US$450M in Share Repurchases This Quarter: MPWR repurchased over US$450M of its own stock this quarter, demonstrating management's confidence in the company's long-term value and continuing an aggressive capital return strategy.
First Large Data Converter Design Win Expands SAM: The company secured its first large data converter design win, with mass production expected to contribute to revenue starting in 2027. CEO Michael Hsing said the company serves many market segments but cannot predict which business will be largest in five or ten years.
