3 US Semiconductor Stocks With Earnings Growth And Valuation Risk

Simply Wall St·06/21/2026 21:15:29
Listen to the news

The latest rebound in technology and semiconductor stocks has put chip companies back in the spotlight, with the sector moving sharply after Intel’s rally on news of a new U.S. chip partnership with Apple. Combined with lower oil prices after the U.S. Iran interim peace agreement, easing inflation worries and steady, if uncertain, Federal Reserve policy guidance, this creates a very different backdrop from just a week ago. This article looks at 3 semiconductor stocks from our screener that appear especially exposed to these developments and explains why some investors are watching them closely right now.

Impinj (PI)

Overview: Impinj operates a cloud connectivity platform that uses tiny RAIN RFID chips and readers to give physical items in retail, logistics, healthcare and other sectors a unique digital identity, so businesses can track and manage them in real time.

Operations: Impinj generates about US$361.0 million in revenue from the development and sale of its RAIN RFID products and services.

Market Cap: US$3.9b

Impinj sits at the intersection of semiconductors and the physical economy. Many investors are watching it closely after the sector’s sharp rebound. Its RAIN RFID platform is tied to long term themes such as food traceability, supply chain visibility and retail automation. Management commentary points to improving demand signals even as the macro picture remains mixed. At the same time, the stock carries real questions, including continued losses, reliance on a handful of large customers and a P/S multiple that is higher than many semiconductor peers. For investors weighing whether that mix of growth expectations, risks and current valuation still stacks up, the full story on Impinj is more nuanced than recent headlines suggest.

Impinj’s combination of real-economy exposure and a richer P/S valuation has many asking whether the market is underestimating the impact if its growth story fully develops or if key risks start to weigh on performance. Get the full context in the full narrative for Impinj

Allegro MicroSystems (ALGM)

Overview: Allegro MicroSystems designs and manufactures sensor and power integrated circuits that help control motion, sense position and manage power in systems such as electric vehicles, industrial equipment, data centers and robotics.

Operations: Allegro generates about US$890.1 million in revenue from designing, developing, producing and distributing a broad range of integrated circuits, with sales spread across Japan, Greater China, Other Asia, Europe, South Korea, the United States and Other Americas.

Market Cap: US$11.0b

Allegro MicroSystems sits at the heart of several themes investors are focused on after the semiconductor rebound, including vehicle electrification, ADAS, industrial automation and AI data centers. Recent results show higher sales with narrowing losses, and guidance that points to continued revenue growth, while analysts expect strong earnings improvement over the next few years. At the same time, Allegro is still loss making, carries higher valuation multiples, leans heavily on automotive demand, and has seen recent insider selling and board turnover. For investors weighing whether that trade off between growth potential and risk still makes sense, there is more to the Allegro story than the headline AI and auto excitement suggests.

Allegro MicroSystems sits at the crossroads of EVs, automation and AI data centers, yet its higher valuation and insider moves raise real questions, so readers often turn to the analyst forecasts for Allegro MicroSystems to see what the earnings gap and automotive reliance might really be signaling

Power Integrations (POWI)

Overview: Power Integrations designs high-voltage analog and mixed-signal chips that convert power efficiently for everything from phone chargers and home appliances to industrial motors, renewable energy systems, electric vehicles and AI data centers.

Operations: Power Integrations generates about US$446.3 million in revenue, almost entirely from integrated circuits and related components.

Market Cap: US$4.9b

Power Integrations is drawing renewed attention as the semiconductor rebound coincides with growing interest in power efficient hardware for AI data centers, renewable energy and electric vehicles. The company has been investing in high voltage GaN products and reference designs tailored to 800 V AI data centers and industrial power projects. Industrial revenue has recently grown, helped by renewable energy, battery storage and home automation demand. At the same time, earnings have been under pressure, margins have contracted, insider selling has picked up and the stock trades on richer multiples than many peers, so expectations are already high. For investors, the real question is whether Power Integrations’ GaN portfolio and industrial exposure can outweigh its consumer reliance, recent earnings volatility and funding risks over time.

Power Integrations’ AI and renewable push could be bigger than the headline story suggests, but the real tension is how that ambition lines up with its earnings swings, so the analyst forecasts for Power Integrations might change how you see the risk reward balance
