• Semiconductor Moderation Reflects Macro and Tariff Dynamics: China softness and DRAM deceleration offset growth in next-gen plasma power platforms.
• Industrial Medical Recovery Underway: Backlog and distributor resales point to gradual improvement, but tariff exposure and customer caution temper the pace.

AEIS is now operating at its highest semiconductor revenue levels outside the COVID-recovery spike, with new product ramps expected to catalyze growth as fab processes scale. The company’s ability to absorb data center mix shifts without margin dilution signals a structurally improved cost base.

Executive Commentary

Strategic Positioning

1. AI-Driven Data Center Expansion

AI workloads are fundamentally reshaping AEIS’s data center addressable market, with power requirements per rack rising 5-10x versus legacy architectures. The company’s high-efficiency, high-density power solutions have become critical for hyperscalers and are now being adopted by enterprise customers, broadening the opportunity set. Management is investing in manufacturing capacity and rapid design cycles to keep pace with annual GPU launches, supporting sustained revenue visibility into 2026 and beyond.

2. Next-Gen Semiconductor Platform Momentum

EVOS, Everest, and NavX platforms, AEIS’s next-generation plasma power solutions, are doubling revenue in 2025, validating customer adoption and early production traction. While overall semiconductor growth has moderated due to tariffs, inventory shifts, and China softness, the underlying technology roadmap is driving design win conversion that should accelerate as new fab processes ramp to volume. The company’s exposure is weighted toward leading-edge logic and DRAM, with less reliance on NAND.

3. Industrial Medical Channel Turnaround

INM’s backlog growth and five consecutive quarters of channel inventory drawdown indicate that the correction phase is ending, setting the stage for gradual recovery. Digital marketing and distributor partnerships are yielding a record number of design wins, many originating from new website inquiries. While market recovery is the near-term driver, these design wins are expected to contribute meaningfully to growth and share gains in 2026.

4. Margin Structure and Tariff Mitigation

AEIS’s exit from China manufacturing and supply chain optimization are structurally improving gross margins, even as tariff costs persist. The company expects to approach 40% gross margin by year-end, with further upside as mitigation strategies mature. Margin dilution from data center mix has been largely neutralized by new product rationalization and cost controls.

5. Capital Allocation and Acquisition Pipeline

Strong cash flow generation is enabling both organic investment and opportunistic buybacks, while the balance sheet supports an active M&A pipeline. Management is targeting acquisitions to broaden scope and leverage scale, with a disciplined approach to integration and capital deployment.

Key Considerations

AEIS’s Q2 reflected a strategic inflection, with the business model shifting toward higher-value, AI-driven data center and next-gen semiconductor platforms. Investors should weigh the durability of these drivers against external risks and execution complexity.

Key Considerations:

• AI Power Cycle Accelerates Content Growth: Each new GPU generation increases AEIS’s attach rate and ASPs, but requires rapid engineering response.
• Tariff Volatility Remains a Margin Wildcard: While mitigation is progressing, over 100 basis points of headwind persists and could worsen if trade dynamics shift.
• Design Win Conversion is Critical for 2026: The scale and timing of new product ramps will determine whether AEIS outgrows its markets next year.
• Industrial Medical Recovery Hinges on Channel Health: Distributor inventory normalization is progressing, but small and midsized customers remain sensitive to tariffs and macro uncertainty.
• Acquisition Integration and Capital Discipline: Future M&A must deliver synergy and not dilute the improved margin structure.

Risks

Tariff policy remains a material uncertainty, with potential to disrupt supply chains and compress margins if mitigation lags or costs escalate. Semiconductor demand is exposed to China weakness and memory cycle volatility, while data center growth could moderate if hyperscaler capex slows. Execution risk is elevated as AEIS juggles rapid design cycles, multiple new product ramps, and ongoing factory transitions. The company’s ability to maintain engineering bandwidth and avoid overextension will be tested as project count rises.

Forward Outlook

For Q3, AEIS guided to:

• Revenue of approximately $440 million, plus or minus $20 million
• Gross margin improvement to around 38.5%, with further gains expected exiting the year
• Non-GAAP EPS of $1.45, plus or minus $0.25

For full-year 2025, management raised guidance:

• Overall revenue growth of approximately 17%
• Data center computing revenue growth upgraded to over 80% (from 50%)
• Semiconductor revenue to grow mid-single digits

Management highlighted several factors that will shape the second half:

• Continued strong AI-related demand and design win ramps in data center
• Tariff mitigation actions and factory consolidation benefits supporting margin expansion

Takeaways

AEIS’s Q2 marks a strategic pivot, with AI infrastructure and next-gen platforms driving a higher growth and margin profile. Margin expansion is holding despite mix shifts and tariffs, and design win momentum is setting up for multi-year outperformance if execution remains disciplined.
