What Happened?

Monolithic Power Systems rose about 34% over the past 6 months, recently trading near $1,108 per share and approaching its $1,256 52 week high.

The advance followed record earnings results, strengthening AI-driven data center demand, and improved order visibility extending into 2026.

The stock moved higher primarily because investors gained confidence in revenue durability and backlog expansion tied to Enterprise Data growth.

Management reported a book-to-bill ratio well in excess of 1, with backlog now extending into Q2 and Q3 2026, signaling stronger forward demand and improving visibility across AI infrastructure, storage, and server power solutions.

This week, the company reported record Q4 revenue of $751.2 million, up 1.9% sequentially and 20.8% year over year, and full year revenue of $2.8 billion, up 26.4%, marking its 14th consecutive year of growth.

Automotive revenue grew 43% in 2025, non-Enterprise Data end markets expanded over 40%, and management raised the quarterly dividend 28% to $2 per share.

CEO Michael Hsing noted that ordering patterns strengthened late in the quarter and that MPS has broad design wins across major AI and hyperscale customers.

Institutional activity has also been active. American Century Companies increased its stake by 18.2% to 214,950 shares worth about $197.9 million, Handelsbanken Fonder AB raised its position by 22.7% to 36,773 shares worth about $33.9 million, and DNB Asset Management lifted its holdings by 8.3% to 27,147 shares valued near $25.0 million.

While Rafferty Asset Management trimmed its position by 28.3%, institutional ownership remains high near 93.5%, with large positions held by Vanguard, JPMorgan, and Norges Bank, reinforcing broader accumulation trends over the past six months.

Is MPWR Undervalued?

Under valuation assumptions, the stock is modeled using:

  • Revenue Growth (CAGR): 19.9%
  • Operating Margins: 36.5%
  • Exit P/E Multiple: 44.8x

Revenue is projected to expand from about $2.8 billion in 2025 toward roughly $4.8 billion by 2028 and over $6.6 billion by 2030, supported by rising power density requirements in AI servers, expanding semiconductor content in automotive systems, and deeper integration across industrial automation platforms.

MPWR Revenue & Analyst Growth Estimates Over Five Years

Enterprise Data remains central. Management increased confidence in 2026 growth after previously guiding to 30% to 40% growth and now suggesting a floor of 50% growth for 2025, with commentary implying potential upside beyond that range.

Strong design wins across hyperscale customers, increasing adoption of vertical power architectures, and module-based solutions position the company to capture higher content per system rather than relying solely on unit volume expansion.

Automotive growth also remains a structural driver. Revenue in the segment rose 43% in 2025, driven by 48-volt architectures, zonal controllers, and increasing ADAS penetration.

As automakers gradually implement higher electronic content per vehicle, MPS benefits from expanding power management complexity rather than depending on overall vehicle production growth.

Operating margins trending toward 36.5% assume continued mix shift toward higher-margin enterprise and automotive programs, along with incremental operating leverage as revenue compounds.

With gross margins in the 55% range and improving backlog visibility, incremental revenue should continue to translate into expanding profitability.

Based on these inputs, the valuation model estimates a target price of $1,687, implying about 48% total upside over the modeled period and a 14.7% annualized return.

At current levels near $1,108, MPWR appears moderately undervalued relative to its forward growth profile, with performance in 2026 likely tied to AI infrastructure deployment pace, automotive electrification adoption, and sustained margin expansion rather than broad semiconductor cycle acceleration.
