Wall Street maintains strong buy on Monolithic Power Systems as AI demand drives outperformance

Wall Street analysts continue to express a highly optimistic outlook on Monolithic Power Systems (MPWR), citing the company’s substantial outperformance of the broader market over the past 52 weeks. The semiconductor firm, which holds a market capitalisation of $78.1 billion, has seen its shares soar 136.5 per cent during this period. This trajectory significantly exceeds the S&P 500 Index ($SPX), which gained 27.9 per cent over the same timeframe, and the State Street Technology Select Sector SPDR ETF (XLK), which rose 57.3 per cent.

On a year-to-date basis, the momentum remains robust, with MPWR up 75.4 per cent compared to the SPX’s 8.1 per cent rise and the XLK’s 25.3 per cent increase. The stock’s performance was bolstered on 30 April when shares jumped 5.7 per cent following the release of first-quarter results that surpassed analyst estimates. The company designs advanced power management solutions for critical infrastructure, including artificial intelligence data centres, cloud computing architectures, and telecom networks.

Financially, Monolithic Power Systems reported first-quarter revenue of $804.2 million, representing a 26.1 per cent year-on-year increase that topped consensus estimates by 3 per cent. Adjusted earnings per share (EPS) came in at $5.10, comfortably exceeding the expected $4.89. Management identified the communications segment as a primary growth driver, supported by strong demand for power solutions in optical modules and switches. Additionally, solid momentum in enterprise data markets, particularly from servers and AI-related deployments, contributed to the quarterly performance.

Looking ahead, analysts expect the company’s EPS to grow 57.4 per cent year-on-year to $20.13 for the current fiscal year ending in December. The consensus rating among the 16 covering analysts remains a "Strong Buy," comprising 12 "Strong Buy," two "Moderate Buy," and two "Hold" ratings. This sentiment is slightly less bullish than two months ago, when 13 analysts held a "Strong Buy" rating. The mean price target stands at $1,820, implying a 14.5 per cent premium to current levels.

KeyBanc analyst John Vinh has raised his price target to $2,000, the highest on the street, maintaining an "Overweight" rating. This target suggests a potential upside of 25.8 per cent from current levels. While the company’s earnings surprise history has been mixed, with two beats and two misses in the last four quarters, the current analyst configuration reflects continued confidence in the firm’s ability to capitalise on the growing demand for energy-efficient, high-density analog and mixed-signal power management solutions.
