SkyWater Technologies (SKYT) Q1 2025: New Products Drive 60% Wafer Services Mix Shift, Positioning for H2 Margin Expansion

May 7, 2025 | By EarningsIQ Research

SkyWater’s first quarter revealed a decisive shift toward innovation-led wafer services, with new platforms like ThermaView rapidly scaling and legacy mix falling to 40% as 2025 begins. Despite ATS revenue softness tied to government funding delays, management’s visibility into H2 program ramp and the pending Fab 25 acquisition signal a step-change in capacity, margin potential, and end-market diversification.

Summary

• Innovation-Led Mix Shift: New products now drive over half of wafer services revenue, accelerating the pivot away from legacy offerings.
• ATS Funding Drag: Federal budget delays deferred program ramps, but management expects a strong rebound in the second half.
• Fab 25 Acquisition Catalyst: Pending Austin fab deal underpins a multi-year expansion in U.S. specialty and foundational chip capacity.

Performance Analysis

SkyWater’s Q1 results reflected a business in strategic transition, with total revenue slightly above guidance midpoint and gross margin outperforming expectations, aided by a one-time warranty accrual reversal. Wafer services revenue outpaced plan, fueled by the ramp of ThermaView, a 90 nanometer CMOS and MEMS platform, and recent conversions from Advanced Technology Services (ATS) to production. This marks a sharp pivot from last year’s 90% legacy wafer mix to a 60% new/40% legacy split in Q1, with management targeting a sustained innovation-driven mix through 2025.

However, ATS revenue softened versus plan as U.S. government budget delays forced key aerospace and defense (A&D) programs to operate at 2024 spending levels, pushing anticipated funding increases into the second half. Adjusted EBITDA and non-GAAP EPS beat guidance, while operating expenses remained tightly managed and capital expenditures were largely customer-funded. The balance sheet strengthened with a $32 million increase in cash, driven by advanced payments for tool purchases, and $7 million in revolver paydown.

• ThermaView Platform Traction: Drove the majority of wafer services upside, validating SkyWater’s co-creation and rapid ramp model.
• Legacy-to-New Revenue Mix Shift: New products now represent 60% of wafer services, a structural reversal from 2024.
• ATS Drag Offsets Growth: Government funding delays weighed on ATS, but management expects a strong H2 snapback.

Management continues to forecast 5% full-year revenue growth for the combined ATS and wafer services businesses, with growth heavily back-end loaded and margin expansion expected as new programs scale and funding normalizes.

Executive Commentary

Strategic Positioning

1. Wafer Services Innovation Pipeline

SkyWater’s wafer services business is undergoing a structural transformation, as new products and platform launches (notably ThermaView) now drive the majority of revenue, with the legacy share falling to 40%. The company’s technology-as-a-service model, which co-creates and transitions new technologies from ATS (engineering and prototyping) to high-volume wafer production, is now delivering tangible results. Management expects continued conversions and design wins across defense, automotive, and medical device verticals, making innovation-led growth the core engine for Minnesota fab utilization and margin leverage.

2. ATS Exposure and Government Program Dynamics

ATS remains SkyWater’s largest business and a key margin lever, but its performance is now tightly linked to U.S. federal budget cycles and program funding. The current quarter was impacted by continuing resolutions that froze spending at prior-year levels. However, management’s confidence in a H2 rebound is grounded in multi-year government investment, ongoing program reviews, and direct customer engagement. The second half is expected to see a strong snapback, with Florida advanced packaging platform development also contributing incremental ATS revenue.

3. Fab 25 Acquisition and U.S. Sovereignty Tailwind

The pending acquisition of Infineon’s Fab 25 in Austin is a step-change for SkyWater’s scale and market reach. Fab 25, a leading 200 millimeter CMOS facility, is backed by a four-year, $1 billion supply agreement and will enable SkyWater to serve both new product development and dual-sourcing for foundational chips. This move positions SkyWater as a critical enabler of U.S. semiconductor sovereignty, with the ability to address specialty analog, mixed-signal, RF, MEMS, and high-voltage markets across automotive, industrial, medical, and defense end-markets.

4. Quantum and Advanced Compute Enablement

SkyWater’s advanced compute segment, now 10% of revenue, is anchored by quantum technology partnerships with D-Wave and PsyQuantum. The company’s role in enabling lab-to-fab breakthroughs for quantum computing—including superconducting and photonic integration—is gaining visibility, especially as D-Wave’s quantum supremacy milestone underscores the strategic importance of secure, domestic chip manufacturing for next-gen compute and AI leadership.

5. Tariff and Supply Chain Resilience

Management views tariff risk as manageable, with no downward revisions in demand from key customers and limited direct exposure compared to global peers. While higher input costs are possible, especially for non-exempt equipment, the defense-heavy revenue mix and domestic manufacturing footprint provide a buffer. Ongoing cost management and potential supplier diversification are expected to mitigate any residual impact.

Key Considerations

This quarter’s results highlight SkyWater’s accelerating transition from legacy to innovation-led revenue, but also expose the business to timing volatility from government funding cycles and the execution risks of scaling new platforms.

Key Considerations:

• Revenue Mix Reversal: The rapid shift to 60% new wafer services revenue is foundational for sustainable growth and margin expansion.
• ATS Funding Volatility: Government budget negotiations remain a swing factor for near-term results, with H2 recovery contingent on timely appropriations.
• Fab 25 Integration Risks: While transformative, the Austin fab acquisition brings integration, customer ramp, and capital deployment challenges.
• Quantum Segment Traction: Advanced compute is emerging as a strategic growth pillar, but remains a small portion of total revenue and is in early commercialization phases.
• Cost Structure and Margin Leverage: Margin expansion depends on scaling new programs above breakeven levels and managing tools-related dilution.

Risks

SkyWater faces material risks from the timing and magnitude of U.S. government program funding, with continued political uncertainty potentially deferring ATS revenue recovery. Integration of Fab 25 introduces operational and customer ramp risks, while any escalation in tariff or supply chain disruptions could pressure input costs and profitability. The company’s margin outlook is also sensitive to program mix and the pace of new product adoption.

Forward Outlook

For Q2, SkyWater guided to:

• Total revenue of $55 to $60 million
• ATS revenue of $49 to $53 million
• Wafer services revenue of $5 to $6 million
• Gross margin of 16% to 19%

For full-year 2025, management maintained guidance:

• 5% combined revenue growth for ATS and wafer services, plus or minus 2%
• Full-year non-GAAP gross margin in the 23% to 27% range, with margin expansion in H2

Management highlighted several factors that will shape results:

• Second half rebound in ATS and wafer services as government funding normalizes
• Fab 25 acquisition expected to close mid-year, with incremental revenue and cash flow to follow

Takeaways

SkyWater’s Q1 marks a pivotal shift to innovation-driven growth, but near-term execution remains hostage to government funding cycles and the operational ramp of new platforms.

• Wafer Services Transformation: The move to 60% new product mix is a structural change, driving higher-margin, more predictable growth as platforms scale.
