What Happened?
Monolithic Power Systems entered earnings with investors focused on whether its rapid AI-driven expansion could continue after the stock’s strong run. Shares surged about 8% on Friday to close near $1,426 as record results and stronger guidance showed that demand for the company’s data-center power products was still accelerating.
The stock rose specifically because Monolithic Power beat Wall Street’s revenue and earnings expectations and issued third-quarter sales guidance well above consensus. Revenue reached a record $980.6 million, up 47.6% year over year and 21.9% sequentially, while adjusted EPS of $6.50 exceeded the consensus estimate of about $5.90. Management guided third-quarter revenue to between $1.14 billion and $1.16 billion, compared with expectations of around $980 million, indicating that demand could strengthen further during the second half of 2026 rather than fade after one strong quarter.
On this week’s earnings call, management said Enterprise Data revenue increased 45% sequentially as existing customers expanded orders, new customers ramped, and demand strengthened across AI servers, central processing units, and high-density power modules. These compact modules combine multiple power components to help increasingly powerful processors operate efficiently, allowing Monolithic Power to sell more content into each server. The company raised its 2026 Enterprise Data growth floor from 85% to 130%, while Tony Balow said book-to-bill remained “well above 1,” meaning new orders continued to exceed shipments while channel inventory remained low.
Analyst revisions reinforced the earnings-driven advance. KeyBanc raised its target from $2,000 to $2,100, Needham lifted its target from $1,750 to $2,000, and Truist increased its target from $1,805 to $1,889 after the report. MPWR’s 47.6% revenue growth also exceeded the latest reported increases of 23% at Texas Instruments and 37% at Analog Devices, although their reporting periods and product mixes differ, highlighting MPWR’s heavier exposure to fast-growing AI power infrastructure.

Is MPWR Stock Fairly Valued?
Under valuation assumptions, the stock is modeled using:
- Revenue Growth (CAGR): 23%
- Operating Margins: 38%
- Exit P/E Multiple: 41x
The 23% revenue-growth assumption requires Monolithic Power to keep gaining power-management content across AI accelerators, server processors, optical connections, and networking equipment, while initial DDR5 orders and more than 1,500 new automotive sockets provide additional growth beyond its existing AI server business.
The company’s shift from individual chips toward complete power solutions could increase revenue per system, while its capacity goal of more than $6 billion must support growth without creating excess costs or underused supply.
The 41x exit P/E remains a premium assumption, so the model’s target of around $1,790 by the end of 2028, representing about 25% total upside and a 10% annualized return, is better viewed as an optimistic outcome that requires sustained growth and continued margin expansion.

The EBIT chart supports part of the margin case, with consensus estimates placing EBIT margins near 38% through 2030, but maintaining that level still depends on higher-value module sales, disciplined spending, and strong demand across data-center products.
At current levels, MPWR appears closer to fairly valued than deeply undervalued, with performance through the remainder of 2026 tied to durable Enterprise Data orders, rising power content per system, and successful ramps in DDR5, 48-volt modules, and future 800-volt data-center products.
