If Monolithic Power Systems Stock Looks Expensive, You Need To Read This

Monolithic Power Systems (MPWR) stock trades at 64.4 times its adjusted earnings for the twelve months ended June 30, 2026. Those earnings add back stock-based compensation after tax. At that multiple, the chipmaker looks steep. The forecast for the next two years, however, puts the same price in another light. Here is how it compares with the profit forecast for fiscal 2026 and fiscal 2027.

What You Pay For Monolithic Power Systems’ Forecast Profit
At the October 20, 2026 close of $1,248.74, Monolithic Power Systems trades at 46.0 times the consensus earnings forecast for fiscal 2026. Against the forecast for fiscal 2027, the stock price sits at 35.1 times earnings, beside 64.4 times trailing adjusted earnings. The analyst table does not clarify whether its forecast earnings are adjusted. Part of the gap may therefore come from the measure.
Those lower multiples mean something only if the company generates a lot of new profit. The consensus forecast projects net income of $1.33 billion in fiscal 2026, up from the $856 million shown for fiscal 2025 in the same analyst table. By fiscal 2027, the forecast reaches $1.75 billion, roughly twice the fiscal 2025 figure.
Monolithic Power Systems’ Forecast Against Its Own Record
The consensus forecast expects Monolithic Power Systems to grow sales by 29.2% in fiscal 2027, reaching $5.37 billion. That is close to the 28.7% sales growth the company reported over the twelve months ended June 30, 2026. Fiscal 2026 requires a larger leap. Forecast sales of $4.16 billion sit about 50% above the $2.78 billion shown in the same table for fiscal 2025.
During the latest quarter, fiscal Q2 2026, sales climbed 47.6% from a year earlier. Management stated on the July 30, 2026 call that every end market grew from the prior quarter, led by enterprise data. For fiscal Q3 2026, management guided sales to a range of $1.14 billion to $1.16 billion, compared with $981 million in fiscal Q2.
The consensus forecast also models a wider net margin than the same analyst table lists for the latest full year. The projected net margin for fiscal 2026 is 32.1%, compared with 30.8% in fiscal 2025. The fiscal 2027 estimate reaches 32.5%, which also exceeds fiscal 2025. A wider margin in a forecast is an assumption, not a result.
Where The Forecast For Monolithic Power Systems Looks Weakest
Fiscal 2027 sales carry the most uncertainty, because management has not given a figure that far out. During the July 30, 2026 call, management noted that 2027 is still too far away to quantify, even while describing the company’s long-term growth drivers as structurally very sound. Analysts also disagree on fiscal 2027: the highest and lowest EPS estimates for that year stand 17.4% apart relative to the consensus average.
Management noted that fiscal Q3 2026 demand is being driven by its data-centric businesses, with enterprise data and communications leading the way. A slowdown in enterprise data orders could leave fiscal 2027 sales short of consensus expectations.
The wider net margin is the other weak spot. Management guided fiscal Q3 2026 GAAP gross margin to a range of 55.2% to 55.8%, roughly flat with the 55.2% reported for fiscal Q2. With gross margins flat, any net margin expansion in the consensus forecast must come from operating leverage—operating expenses growing more slowly than sales. If spending keeps pace with revenue, the profit forecast for both years will have to come down.
If the consensus forecast holds true, pricing the stock against projected profit offers a fair picture of what Monolithic Power Systems costs. The forecast is most likely to fall short on fiscal 2027 sales. A shortfall there would leave the stock a riskier holding, priced on profit the company has yet to earn. The next look arrives with the fiscal Q3 2026 report, expected on or around October 29, 2026. Watch quarterly sales against management’s guidance.
