GET DAILY SIGNALSKLAC vs MPWR: Two AI Semiconductor Stocks Down -30% from Highs
Key Takeaways
- KLAC (KLA Corporation) dominates semiconductor process-control and inspection equipment, while MPWR (Monolithic Power Systems) supplies analog power-management chips that benefit from the AI data-center expansion.
- Both stocks have fallen roughly 30% from recent highs even as revenue growth accelerated, a move that mirrors a broader re-rating in AI-related semiconductor names rather than any company-specific issues.
- MPWR is expanding more rapidly, with revenue up about 63% year over year, but it trades at a premium valuation and shows higher volatility; KLAC delivers steadier growth, record operating margins, and stronger free-cash-flow generation.
- Tickeron AI Verdict: Based on trend consistency, stability, cash-flow quality, and relative market positioning, Tickeron's AI currently favors KLAC over the two names.

Why These Stocks Matter for AI Investors
Both KLAC and MPWR are closely tied to the buildout of AI infrastructure, yet they sit at different points in the supply chain. KLAC supplies the inspection and measurement tools that chipmakers rely on to produce advanced semiconductors, while MPWR provides the power-management chips that power servers, accelerators, and other systems. Comparing them helps clarify relative performance, growth durability, valuation, and positioning inside the semiconductor sector amid elevated volatility. I also checked this using Tickeron’s AI Screener to see how the stocks compare to others in the industry.
KLAC Overview and Recent Results
KLA Corporation (KLAC) develops process-control and process-enabling solutions for wafer, reticle, and integrated-circuit manufacturing. Its Semiconductor Process Control segment accounts for most revenue, and the company holds a leading share of the inspection and metrology market—roughly seven times larger than its nearest competitor, according to management.
In the latest quarter, KLAC reported revenue of about $4.14 billion, up approximately 29% year over year, with non-GAAP earnings per share beating estimates. Management guided for a solid sequential increase next quarter and raised its calendar 2026 wafer-fab-equipment market outlook, pointing to stronger AI-driven spending, leading-edge logic, high-bandwidth memory, and advanced packaging. Operating margins hit record levels and free cash flow improved sharply.
Even with these results, KLAC shares have dropped roughly 30% from their recent peak, in line with pressure across semiconductor equipment peers. Memory-component cost pressures have weighed on gross-margin expectations, though management expects margins to move back toward target levels over the next year.
MPWR Overview and Recent Results
Monolithic Power Systems (MPWR) designs high-performance analog and mixed-signal power-management solutions for data centers, automotive, communications, industrial, and computing uses. The company follows an asset-light model and has expanded capacity through partnerships, including a long-term agreement with GlobalFoundries.
In its most recent quarter, MPWR surpassed the $1 billion quarterly revenue mark for the first time, posting sales of roughly $1.20 billion, up about 63% year over year. The Enterprise Data segment, tied to AI and server power, jumped more than 160% year over year and now makes up over 40% of total revenue. Management raised its full-year Enterprise Data growth outlook and guided for another sequential revenue increase, citing customer diversification, wider power-module adoption, and early progress in automotive 48-volt and robotics applications.
Nevertheless, MPWR shares have been volatile, with dozens of single-day moves exceeding 5% over the past year, and the stock trades roughly 29% below its 52-week high. The premium valuation and growing revenue concentration in data-center power have kept sentiment mixed despite the strong fundamentals.
Head-to-Head Comparison
The two companies serve distinct parts of the semiconductor value chain. KLAC is a capital-equipment supplier whose revenue tracks chipmakers’ capacity expansion and process-control needs, offering broad exposure across foundry, logic, and memory. MPWR is a component supplier whose growth is more directly linked to AI server power, creating greater concentration but also tighter leverage to near-term data-center spending.
On growth, MPWR leads with revenue expansion above 60% versus roughly 29% for KLAC. On stability, KLAC shows a steadier profile with higher margins, recurring services revenue, and stronger free-cash-flow generation. MPWR carries a richer valuation multiple and greater share-price volatility. Risk factors differ as well—KLAC contends with memory-cost margin pressure and supply-chain constraints, while MPWR faces customer-concentration risk and competition in integrated power modules. Both remain exposed if AI infrastructure spending slows.
Tickeron AI Verdict
After weighing trend consistency, stability, cash-flow quality, and relative positioning, Tickeron's AI currently leans toward KLAC as the more favorable of the two. The preference reflects KLAC’s dominant market share, record operating margins, recurring services base, and a comparatively more reasonable valuation, along with management’s upwardly revised industry outlook. MPWR offers stronger near-term growth momentum and clear catalysts in AI power, yet its higher multiple and elevated volatility add more uncertainty. As with any probabilistic assessment, this view reflects current observable conditions rather than a guarantee of future results.
