Analysis
MPS delivered record quarterly revenue of $980.6 million, up 21.9% from Q1'26 and 47.6% from Q2'25. The result reflected sequential growth across all end markets. Enterprise Data was the principal growth engine, with revenue of $380.6 million, up 44.8% sequentially and 164.3% year over year, driven by AI and server power-management solutions. Communications also expanded strongly, rising 18.0% sequentially and 78.3% year over year.
Mix shifted toward Enterprise Data, which represented 38.8% of Q2'26 revenue compared with 32.7% in Q1'26. Storage & Computing increased 14.6% sequentially to $199.8 million, while Automotive increased 3.1% to $157.1 million. Consumer rose 4.2% sequentially to $56.8 million but was down 4.8% year over year. Management cited initial DDR5 component orders and sampling of High Voltage AC to DC products for 800V data center architectures as expansion opportunities.
Profitability improved despite higher operating expenses. GAAP operating margin increased to 31.0% from 30.0%, while non-GAAP operating margin increased to 37.5% from 35.8%. GAAP net income was $257.3 million and non-GAAP net income was $320.1 million. GAAP gross margin was 55.2%, 0.1 percentage points below Q1'26, while non-GAAP gross margin increased 0.1 percentage points to 55.6%. Total stock-based compensation and related expenses were $53.5 million, including approximately $1.8 million charged to cost of goods sold.
Liquidity remained substantial, with cash, cash equivalents and short-term investments of $1,413.8 million. Operating cash flow was $227.9 million, compared with $250.3 million in Q1'26. Internal inventories increased to $675.8 million, while days of inventory using current quarter revenue declined to 140 Days from 157 Days. The board authorized an additional $500 million for stock repurchases, bringing total current authorization to $1 billion.
The Q3 outlook calls for revenue of $1,140 million to $1,160 million, with GAAP gross margin of 55.2% to 55.8% and non-GAAP gross margin of 55.4% to 56.0%. Management also forecast GAAP operating expenses of $252.7 million to $258.7 million and non-GAAP operating expenses of $201.2 million to $205.2 million. The guide places continued focus on Enterprise Data demand, margin stability, operating-expense growth, and the company's ability to execute amid the geopolitical and macro-economic environment it described as fluid.

AlphAI analysis generated from the company’s SEC earnings filing (Form 8-K Item 2.02, or Form 6-K for a foreign private issuer).

Background
This is an SEC 8-K filing with Exhibit 99.1 summarizing Monolithic Power Systems Q2 2026 results and commentary, including end-market revenue trends and product/capacity updates.
Ticker impact
Monolithic Power Systems reported Q2 2026 revenue of $980.6M, up 21.9% QoQ and 47.6% YoY, with GAAP EPS $5.22.
Likely positive near-term bias as investors focus on record revenue, rising Enterprise Data mix, and capacity expansion.
The filing provides fresh quarterly financials and segment growth rates, plus product sampling and capacity goal extension, which can support forward demand expectations.
Market effects
Strength in Enterprise Data and communications power solutions reinforces demand signals for AI/server power and optical module infrastructure.
No explicit regional impact disclosed beyond global supply chain diversification.
AI and data center power architecture progress (800V sampling) can be read across to broader semiconductor and power-management demand.
Counterpoint
Margin is only slightly down on a GAAP basis and opex rose, so upside may be more growth-led than profitability-led.
