Buy Analog-Mixed Signal Players MACOM, Monolithic & Semtech

About the Industry

The electronic gadgets we use to accurately read our commands, and record, store, retrieve and process the information we throw at them run on semiconductor technology, whether analog (enabling the recording and measurement of real-world information), digital (processing information available in machine-readable language) or mixed signal (enabling conversion of analog signals to digital or digital to analog among other things). Most electronic gadgets use a combination of these components, whether in consumer, industrial, auto, medical, communications, or IoT and other markets.

The industry is cyclical and prices are elastic. Players usually serve multiple markets that offset their individual seasonality, or focus on certain core markets for which they have highly differentiated technology and relationships.

Growth Prospects Strong Despite Macro and Geopolitics

• The rapid growth of artificial intelligence and data-center infrastructure has emerged as an increasingly important growth driver for the analog and mixed-signal semiconductor industry. AI computing is increasing demand not only for GPUs and memory but also for the supporting semiconductor infrastructure required to power, connect and control increasingly dense computing systems. AI data centers require sophisticated power-management and power-delivery solutions, high-speed signal conditioning, optical and electrical connectivity, timing components and thermal-management technologies. As AI clusters scale, rising power consumption and increasing data-transfer speeds are driving greater semiconductor content per system, creating significant opportunities for suppliers of analog, mixed-signal, power and high-speed connectivity products.

• Analog and mixed-signal semiconductor demand continues to be driven by several powerful and interconnected secular trends. Foremost among them is the rapid electrification of transportation, particularly the rise of electric vehicles, which significantly increases demand for analog components such as power management ICs, battery monitoring systems and sensor interfaces. Closely related is the expansion of IoT and edge devices, where billions of connected nodes rely on mixed-signal chips with ultra-low power consumption. Industrial automation is another major driver, as smart factories and Industry 4.0 applications depend heavily on precise sensing, control systems and predictive maintenance enabled by these technologies. In parallel, the rollout of 5G and advanced connectivity infrastructure is fueling demand for high-performance RF components, data converters and timing solutions that rely on mixed-signal integration. Additionally, the global energy transition is accelerating the need for advanced power management systems in renewable energy, EV charging and smart grid applications, making power analog the largest segment in the market. While consumer electronics continue to contribute, their growth has matured, shifting focus from volume expansion to increased functionality per device, which still raises analog content. While elevated memory prices are likely to pressure consumer electronics and other memory-intensive applications, AI infrastructure spending is increasingly offsetting this weakness. Consequently, the outlook for analog and mixed-signal semiconductors is becoming increasingly differentiated by end market rather than being uniformly cyclical.

• In general, semiconductor pricing is robust when capacity is tight and utilization high. Companies start adding capacity when they anticipate the next big growth cycle which usually continues for several years. AI is a major driver of the current build cycle and AI demand is expected to remain strong for years to come, lengthening the cycle and supporting prices. Supply chain efficiency also has an effect on chip prices. The significant increase in chip demand is driven by AI, data centers, IoT and EVs and strategic imperatives for countries in the race to technological superiority. However, capacity constraints are becoming increasingly evident in certain mature and specialty processes, including 200mm manufacturing platforms commonly used for analog, power and other mature-node semiconductor products. AI-related demand is competing for some of the same manufacturing resources, and foundries are also reallocating capacity toward higher-margin products. Therefore, pricing should remain relatively resilient in the foreseeable future, particularly for differentiated products and those facing capacity constraints.

• The push toward greater system integration and application-specific solutions is significantly reshaping the analog/mixed-signal industry. The need to reduce system cost, power consumption and physical footprint is driving companies to integrate analog, digital, sensing, processing and connectivity functions into highly integrated solutions. This shift is being enabled by advanced process technologies like CMOS scaling and specialized nodes (for example SOI and BiCMOS). This raises the technical complexity of design, especially in noise isolation, signal integrity and mixed-signal verification, increasing development time and demand for specialized analog design talent. It can also increase the value per chip, as customers pay more for integrated solutionsthat reduce system complexity and development costs. Leading analog and mixed-signal companies like TXN, ADI, Infineon, STM and NXP are increasingly developing highly integrated, application-specific solutions, particularly in automotive, industrial and communications markets.

3 Stocks Worth Buying

Despite growing macro uncertainty, a cyclical recovery and strong industrial and AI demand are serving as powerful tailwinds for the industry. The following stocks are worth a closer look:

MACOM Technology Solutions (MTSI): Headquartered in Lowell, Massachusetts, MACOM designs and manufactures high-performance semiconductor products for the data center, telecommunications, and industrial and defense markets. MACOM’s semiconductor solutions are used across high-speed optical networking, wireless infrastructure, radar, aerospace and defense, and high-performance computing applications.

The company is benefiting from strong AI infrastructure demand, an expanding optical connectivity portfolio and emerging opportunities in satellite communications. A key growth driver is the rapid buildout of AI data centers, which require increasingly high-speed, low-latency connections between processors, switches and other components. MACOM supplies critical optical and analog components used in these connectivity systems, positioning it as an important semiconductor supplier to AI networking infrastructure. The company is expanding its exposure to higher-speed optical technologies, with solutions supporting 800G and 1.6T connectivity and emerging 3.2T architectures.

MACOM is also expanding its opportunity in satellite communications, particularly as low-Earth orbit (LEO) networks drive demand for higher-frequency and higher-bandwidth connectivity. Its RF and optical solutions support satellite communications, providing an additional growth opportunity beyond traditional telecommunications and data centers.

That said, MACOM’s growth is increasingly tied to the AI data-center investment cycle, creating exposure to a potentially cyclical and concentrated market. Its dependence on hyperscalers could amplify this risk, as delays or reductions in customer capital spending could materially affect demand. Competition in optical connectivity could pressure pricing and margins as higher-speed technologies become more standardized. The company also faces execution risks as it ramps 1.6T and 3.2T products, particularly as competition intensifies in next-generation optical connectivity. Meanwhile, satellite communications remains an emerging opportunity and is not yet a significant contributor to revenue.

MACOM‘s third quarter earnings beat the Zacks Consensus Estimate by 4.5%. The estimates for fiscal years 2026 and 2027 (ending September) are up 45 cents (9.1%) and $1.49 (22.7%), respectively, in the last 30 days. This represents revenue and earnings growth of a respective 36.8% and 55% in 2026 and 35.8% and 49.7% in 2027.

Shares of this Zacks Rank #1 (Strong Buy) company have appreciated 105.8% in the past year.

Monolithic Power Systems, Inc. (MPWR): Headquartered in Kirkland, Washington, Monolithic is a fabless semiconductor company that develops high-performance power-management and power-conversion solutions. The company serves a diversified range of markets, including storage and computing, enterprise data, automotive, communications, consumer and industrial applications.

MPWR is increasingly positioned to benefit from the rapid rise in power requirements across AI infrastructure and other high-performance computing applications, with recent results indicating a significant acceleration in demand. Total revenue increased 47.6% year over year in the second quarter of 2026, highlighting the strength of the company’s overall growth trajectory. Enterprise Data revenue surged 164.3% year over year in the quarter, on the back of 97.7% growth in quarter one, after declining 2% in 2025.

The sharp rebound reflects accelerating demand for AI and server power-management solutions, positioning Enterprise Data as an increasingly important growth driver for the company. As AI servers require increasingly dense and efficient power delivery, the company stands to benefit from rising power content per system as it develops more compact, high-power and efficient solutions, advanced packaging technologies and next-generation architectures such as 800V data-center power.

Importantly, growth extends beyond AI: communications revenue was up 78.3% in the quarter, while automotive and industrial increased 8.2% and 17.3%, respectively. In 2025, automotive revenue grew 43.1%, communications 36.8%, storage and computing 46.0% and industrial 35.3%. This diversification implies multiple secular growth avenues while reducing reliance on any single market. Its increasingly integrated power solutions and modules can further increase content per system across served markets, strengthening customer relationships and supporting the company’s long-term growth opportunity.

Given the recent growth trajectory, expectations for AI-driven growth have risen sharply, increasing the risk of disappointment if data-center capital spending slows or is delayed. Sustaining triple-digit Enterprise Data growth will also become more difficult as the base expands, while customer concentration and dependence on large hyperscalers could make revenue growth more volatile if customers alter their spending plans.

The company faces additional execution risks as it ramps next-generation architectures such as 800V data-center power. Competition remains intense, while a premium valuation leaves limited room for execution shortfalls and could result in significant multiple compression if AI growth moderates.

Monolithic Power‘s second quarter earnings beat the Zacks Consensus Estimate by 10.5%. The estimates for fiscal years 2026 and 2027 (ending December) are up $2.93 (12.1%) and $4.88 (16.3%), respectively, in the last 30 days. This works out to expected revenue and earnings growth of 46.4% and 52.6% in 2026 and 26.3% and 28.1% in 2027.

Shares of the Zacks Rank #1 company have appreciated 51.7% in the past year.

Semtech Corporation (SMTC): Camarillo, California-based Semtech is a semiconductor and connectivity company providing high-performance solutions for data centers, communications infrastructure, industrial applications and IoT. Its portfolio spans high-speed signal-integrity products for optical and copper data communications, analog and mixed-signal solutions, and wireless connectivity technologies including LoRa®. The company also provides IoT modules, gateways and connectivity solutions supporting cellular and other wireless networks.

Semtech is benefiting from improving demand across its data-center, industrial and IoT businesses, with recent results showing accelerating growth and expanding margins. Data-center revenue increased 91% year over year in the latest quarter, outpacing 33% growth in total company revenue, as AI-driven increases in bandwidth and connectivity requirements support demand for its optical and connectivity products. FiberEdge and CopperEdge products position the company to benefit from rising bandwidth requirements, as increasingly demanding applications drive higher component content per system.

Beyond data centers, LoRa-enabled solutions are supporting growth in industrial and IoT applications by providing low-power, long-range connectivity for connected devices and infrastructure. The improving growth profile is translating into stronger operating leverage, with Q2 FY2027 adjusted operating margin expanding to 24.4% from 18.8% a year earlier.

The combination of accelerating data-center demand, expanding content per system, growing IoT adoption and strong margin expansion provides a solid foundation for sustained earnings growth.The stock increasingly reflects the AI/data-center opportunity but must execute successfully on a rapid transition toward higher-speed optical connectivity. At the same time, it remains meaningfully exposed to cyclical markets. If AI spending slows, the company’s other businesses may not be strong enough to offset weaker data-center demand, leaving the shares vulnerable to a pullback.
