Monolithic Power was quoted at $1,450 at 6:58 p.m. EDT, rising 10.2% compared to Thursday’s closing price of $1,316.18. Regular U.S. trading had finished, but after-hours trading was still active.

Stock chart for NASDAQ:MPWR

The company projected its third-quarter revenue in the range of $1.14 billion to $1.16 billion. The midpoint of $1.15 billion indicates 17.3% growth from the previous quarter. This figure is 16.5% higher than a consensus estimate compiled before the report.

The growth composition sends a clearer signal to investors. Enterprise Data and Communications contributed $294.3 million of the $316.0 million rise in yearly sales, accounting for 93.1% of growth from 52.2% of total revenue.

The skew results in significant operating leverage. It further positions data-center and networking demand as the primary variable influencing estimates.

Revenue for the second quarter was $980.6 million, an increase of 47.6% compared to the same period last year. Adjusted earnings, or non-GAAP earnings per share, came in at $6.50. Both results surpassed analyst expectations, with each of the six end markets showing sequential growth.

The company’s previous guidance stood at $890 million to $910 million. StockStory’s aggregated estimates are used for analyst comparisons.

Chief Executive Michael Hsing stated the quarter demonstrated “the strength of our diversified model.” He additionally pointed to the company’s move toward full-service power solutions.

Enterprise Data revenue climbed 164.3% to $380.6 million, which management attributed to demand for AI and server power offerings. Communications revenue increased 78.3%, supported by growth in optical modules and switches.

Fresh product launches expand that opportunity, following early high-speed DDR5 memory orders. The company initiated sampling of high-voltage AC-to-DC solutions for 800-volt data-center infrastructure. Planned capacity now surpasses $6 billion by a substantial margin.

Profitability increased alongside sales, as the adjusted gross margin remained close to 55.6%. The adjusted operating margin climbed to 37.5%, a rise of 2.7 percentage points compared with a year ago.

Inventory increased by 9.1% from the prior quarter to $675.8 million, remaining behind the pace of revenue growth. Inventory days declined by 17 to 140. Cash and investments stood at $1.41 billion.

The board increased its repurchase authorization by $500 million, raising the total to $1 billion. This represents roughly 1.5% of the cash-close market capitalization. The market response is largely focused on the company’s operating prospects.

The stock was cash-close valued significantly higher than two other analog-chip peers.

Thursday’s regular-session prices were used for market data.

The early postmarket increase raises the trailing price-to-earnings ratio to almost 104. This intensifies the challenge of delivering results following the rally sparked by earnings.

The stock rose 1.7% last week and then dropped 1.3% by Thursday’s market close. After-hours trading indicated shares were 8.7% higher compared to last Friday.

Friday’s open will gauge the after-hours reaction. In the coming week, investors will monitor estimate changes relative to the third-quarter earnings consensus of $6.49 per share set before the report.

Risks stay elevated as just two segments are now responsible for the majority of incremental growth. Estimates may be affected by softer AI investment, optical demand, export restrictions or supply limitations. With a preliminary trailing multiple close to 104 times, there is limited tolerance for any disappointments.

Further analysis

How solid were Monolithic Power’s results for the second quarter?

Second-quarter revenue rose to $980.6 million, marking a 47.6% increase year-over-year. This figure surpassed the upper end of management’s previous guidance by $70.6 million, or 7.8%. GAAP diluted EPS came in at $5.22, and non-GAAP diluted EPS was $6.50. GAAP operating margin improved by 6.2 percentage points to reach 31.0% for the quarter. The company delivered notably strong results for the period.

How does the third-quarter guidance reflect on expected growth and earnings?

Management projected third-quarter revenue in the range of $1.14 billion to $1.16 billion. The midpoint, $1.15 billion, represents sequential growth of 17.3% and year-over-year growth of 56.0%. For non-GAAP gross margin, the company expects between 55.4% and 56.0%. Based on the midpoint of the provided guidance and unchanged foreign-exchange rates, adjusted EPS is estimated at about $7.68. This figure is an analyst estimate and not official company EPS guidance.

Is it possible for 2026 revenue to surpass $4 billion at this point?

Revenue for the first half reached $1.785 billion as of June, marking a 37.1% increase from the same period in 2025. Including the midpoint of third-quarter guidance brings nine-month revenue close to $2.935 billion. At that pace, MPS would need $1.065 billion in the fourth quarter to hit the $4 billion mark, a target 7.4% lower than the third-quarter midpoint. Matching the third-quarter midpoint once more would result in about $4.085 billion for 2026. Management has yet to provide official full-year revenue guidance.

To what extent does present growth rely on AI data centers?

Reliance remains strong but not total. Enterprise Data delivered $380.6 million, accounting for 38.8% of revenue in the quarter, with sales up 164.3% from a year earlier. Communications, primarily from optical modules and switches, added $131.5 million, representing a 78.3% increase. Combined, these two sectors made up 52.2% of the quarter’s revenues. Consumer revenue declined by 4.8%, while Storage and Computing posted modest growth of 2.3%. While DDR5 orders and 800-volt sampling are expanding the product pipeline, the outlook for coming revenue is still unclear.

Do margin gains sufficiently support the current valuation?

GAAP operating margin improved to 31.0% from 24.8% a year ago. Adjusted operating margin increased by 2.7 percentage points to 37.5%. Gross margin was little changed, so more moderate expense growth accounted for most of the margin expansion. Shares are trading at $1,316.18, equal to about 62 times trailing adjusted EPS. At approximately $1,454 in after-hours trading, the multiple is nearly 69 times. Using the $7.68 midpoint estimate on an annualized basis brings the multiple down to around 47 times, assuming the pace continues. Valuation remains high at both levels.

How did MPWR perform compared to the wider market?

MPWR ended regular trading at $1,316.18, advancing 5.4% on the session. The S&P 500 added 1.66%, while leading analog competitors posted smaller gains. After-hours trades were mostly quoted around $1,454, marking a further 10.5% jump from the close. Post-market pricing fluctuated across different platforms and timestamps. Shares are still trading about 15% below the May peak of $1,714.09. Volume in the main session rose to 1.7 million shares, surpassing the average of 965,353. marketwatch.com

What do inventory, cash flow, and shareholder returns indicate?

As of June, cash, equivalents and short-term investments totaled $1.414 billion. Operating cash flow for the first half reached $478.2 million, compared with $450.5 million in GAAP income. Inventory was up 37.8% from the prior year to $675.8 million, but inventory days dropped to 140 from 150. The approved $1 billion buyback represents approximately 1.5% of the company’s regular-close market value. The quarterly dividend of $2 offers a yield of about 0.61% based on the regular-close. While cash generation remains strong, the direct yield to shareholders is still limited.

What risks should be prioritized at this time?

Two immediate risks are notable: demand concentration and financial-reporting controls. Enterprise Data makes up 38.8% of total revenue, increasing vulnerability to a pause in AI investment. The 2024 deferred-tax correction lowered reported net income by $194.6 million. Auditors identified ineffective controls regarding the review process for deferred-tax calculations. Management aims to fix these issues by the end of 2026, but has not committed to a completion date. Export controls, tariffs, supplier capacity limitations, and exposure to China are further operational risks. These remain significant concerns. SEC

What do analysts’ existing price targets suggest?

Published consensus from analyst aggregators lists average price targets between roughly $1,520 and $1,777, with top estimates commonly at about $2,000 per share. Based on the $1,316.18 regular session close, this translates to an implied upside of approximately 15%–35%. At an after-hours price of $1,454, that range narrows to around 5%–22%. The number of analysts and the timing for target updates vary significantly between the three aggregator platforms. These numbers might not fully capture the latest model revisions post-results.
