SkyWater vs. Semtech: Which Semiconductor Stock is the Better Buy?

The semiconductor market is projected to grow 11.2% to $700.9 billion by 2025, primarily driven by AI, creating opportunities for SkyWater Technology (SKYT) and Semtech Corporation (SMTC). Semtech (SMTC), rated Zacks #2 (Buy), exhibits stronger near-term growth, reporting record Q1 FY26 data center revenue of $51.6 million (up 143% YoY) and leveraging its low-power interconnects for AI/ML hyperscalers, despite valuation concerns. SkyWater (SKYT), a Zacks #3 (Hold), is strategically positioned as the sole DMEA-accredited U.S. trusted foundry, expanding capacity with the $73 million Fab 25 acquisition to support domestic chip production and quantum computing, though its growth visibility is longer-term. Both stocks are down over 20% YTD, but Semtech's direct AI infrastructure alignment provides a near-term advantage.

Analysis

The semiconductor market is projected for robust growth, with the World Semiconductor Trade Statistics organization forecasting an 11.2% increase in sales to $700.9 billion in 2025, creating a favorable macro environment for both SkyWater Technology (SKYT) and Semtech Corporation (SMTC). Semtech is demonstrating significant near-term momentum directly tied to the artificial intelligence infrastructure build-out, reporting record data center revenue of $51.6 million in its first quarter of fiscal 2026, a 143% year-over-year increase. This growth is driven by its CopperEdge product line's adoption by hyperscalers, underpinning a strong fiscal 2026 earnings forecast of an 88.64% year-over-year increase. This operational strength, however, is contrasted by a high valuation, with a forward Price/Sales ratio of 3.87X. Conversely, SkyWater Technology is positioned as a longer-term, strategic play on U.S. semiconductor reshoring. Its status as the only DMEA-accredited Category 1A trusted foundry is fortified by the recent $73 million acquisition of Fab 25, which significantly expands its domestic manufacturing capacity. While SKYT reported Q1 2025 revenue of $61.3 million, its earnings are projected to decline in 2025, and its growth is more exposed to federal spending cycles. Despite both stocks registering year-to-date declines over 20%, SKYT offers a more attractive valuation at a 1.43X forward Price/Sales multiple, presenting a clear trade-off between SMTC's immediate AI-driven growth and SKYT's strategic, capacity-led potential.

Key Decisions for Investors

• Investors seeking direct, near-term exposure to the AI data center boom should focus on Semtech (SMTC), which exhibits strong revenue acceleration and an 88.6% projected earnings growth, but must be comfortable with its premium valuation.
• For those with a longer-term thesis on U.S. semiconductor independence and strategic manufacturing, SkyWater (SKYT) offers a compelling entry point given its lower valuation and capacity expansion through the Fab 25 acquisition, though this requires patience for its earnings to inflect positively.
• Given both stocks have fallen over 20% year-to-date, risk-conscious investors should monitor SMTC's ability to sustain its momentum against competitors and SKYT's successful integration of Fab 25 and its ability to convert its strategic position into consistent revenue growth.
