Amtech Systems (ASYS) Q3 2023: Silicon Carbide Bookings Exceed Prior Year, Offset Semi Weakness

August 9, 2023 | By EarningsIQ Research

Silicon carbide consumables bookings at Amtech Systems are now at or above last year’s full-year totals, signaling robust demand in a key growth vector even as advanced packaging and S&T markets remain soft. Operational missteps, notably ERP implementation challenges and shifting customer delivery dates, weighed on quarterly execution and cash flow. Management’s forward tone is one of cautious optimism, with incremental improvement expected but no near-term demand inflection in core semi equipment.

Summary

• Silicon Carbide Outperformance: Bookings from top silicon carbide customers have already matched or exceeded all of last year’s totals.
• ERP and Delivery Disruption: Operational issues and customer shipment delays constrained revenue and cash flow.
• Incremental Improvement Expected: Management guides for modest sequential gains but remains wary of semi cycle timing.

Business Overview

Amtech Systems designs, manufactures, and sells capital equipment and consumables for the semiconductor, electronics, and power device industries. The company’s revenue is primarily generated from three segments: semiconductor equipment, high-temperature belt furnaces (notably for electric vehicles), and a materials and substrate division with a focus on silicon carbide consumables. Its customer base includes semiconductor manufacturers, outsourced assembly and test (OSAT) providers, and electronics manufacturers globally.

Performance Analysis

The quarter highlighted a sharp divergence between end markets: while overall revenue fell sequentially, year-over-year growth was strong, driven by the Intrepix acquisition and continued strength in high-temp belt furnace shipments. The sequential revenue decline was mainly due to $1.5 million in delayed shipments—half attributed to ERP system implementation issues and half to customer-driven delivery pushes. Gross margin compressed sequentially, reflecting a less favorable product mix in the semiconductor segment, though it improved versus the prior-year period when Shanghai operations were shuttered by COVID restrictions.

Operating expenses rose year-over-year due to the addition of Intrepix and ERP project costs, but fell sequentially as acquisition costs rolled off. Cash consumption remained a concern, with the quarter seeing outflows for ERP investments, pre-acquisition liabilities, and lower contract advances. Inventory levels, though down sequentially, remain elevated due to backlog in high-temp belt furnaces and the Intrepix integration. Non-GAAP profitability was positive but much lower than the prior quarter, underscoring execution challenges and soft demand in core semi markets.

• Silicon Carbide Consumables Strength: Year-to-date bookings from top customers matched or exceeded all of last year, a bullish signal for this growth line.
• Advanced Packaging Weakness: Demand for Paramax and S&T products remained persistently low, with no near-term rebound expected.
• ERP Implementation Drag: System rollout at Pierre Hoffman disrupted production planning and contributed to revenue shortfall.

Despite these headwinds, Amtech’s competitive positioning in silicon carbide and high-temp furnaces provides a foundation for future growth, provided operational execution stabilizes and the semi cycle turns upward.

Executive Commentary

Strategic Positioning

1. Silicon Carbide Leadership

Amtech’s materials and substrate division is capitalizing on industry-wide migration to silicon carbide, a material that enables higher efficiency in power electronics and electric vehicles. The company’s consumables are highly differentiated, providing cost and performance advantages, and bookings from leading customers are already at or above last year’s full-year levels. This positions Amtech to ride secular growth in EVs and power electronics as wafer capacity ramps globally.

2. Advanced Packaging Exposure

The advanced packaging and S&T segment remains in a cyclical trough, with persistent low demand and uncertain timing for recovery. Amtech continues R&D investment and maintains constructive OSAT customer dialogue, but macro uncertainty is delaying a rebound. The company believes its technology and relationships will allow it to capture share when the cycle turns, but near-term visibility is limited.

3. Operational Execution and ERP Transformation

ERP implementation at Pierre Hoffman proved more disruptive than planned, impacting production planning and causing shipment delays. Management asserts that the “go-live” phase is now past, with production ramping back up, but the episode highlights execution risk as the company integrates acquisitions and modernizes systems. Future operational discipline will be critical as Amtech seeks to scale in growth markets.

4. Capital Allocation and Cash Discipline

With cash consumption persisting for three consecutive quarters, management’s near-term focus has shifted to cash collections, improving the cash conversion cycle, and maintaining liquidity. Share repurchases are not currently prioritized, and the company retains a fully available $8 million revolver as a liquidity backstop.

Key Considerations

The quarter’s results expose the crosscurrents shaping Amtech’s outlook, with secular tailwinds in silicon carbide offset by cyclical and execution headwinds in core semi equipment. Investors should weigh the following:

Key Considerations:

• Booking Momentum in Growth Markets: Silicon carbide-related consumables are seeing strong, sustained order flow, supporting the company’s long-term thesis.
• Execution Risk Remains Elevated: ERP system challenges and shipment delays highlight the need for operational rigor as the business scales.
• Cash Management Focus: With ongoing cash outflows, disciplined working capital and collections are now a top priority for management.
• Segment Divergence: High-temp belt furnaces and silicon carbide are outperforming, while advanced packaging and S&T remain weak, creating mixed visibility across the portfolio.

Risks

Amtech faces several material risks: continued softness in advanced packaging and S&T markets could prolong the earnings trough, while further operational missteps—especially in ERP and integration—could constrain margin recovery. Cash consumption and inventory build present liquidity risks if order timing or customer payments slip. Currency fluctuations, particularly RMB/USD, and cyclicality in semiconductor equipment markets, further complicate forecasting and execution.

Forward Outlook

For Q4 2023, Amtech guided to:

• Incremental improvement in revenue and operating profit over Q3
• Continued operational focus on cash collections and working capital

For full-year 2023, management did not provide specific guidance but emphasized:

• Expectations for further improvement as ERP headwinds subside
• Ongoing volatility tied to order timing, customer shipments, and macro demand

Management highlighted that results will be impacted by order timing, logistics, and macro demand cycles, with actual outcomes potentially diverging materially from expectations.

• ERP stabilization is expected to support Q4 revenue rebound
• Silicon carbide momentum to continue, but semi recovery timing remains uncertain

Takeaways

Amtech’s Q3 was defined by end-market divergence and operational disruption, but the company’s positioning in silicon carbide and power electronics remains a structural positive for the long term.

• Growth Vector Outpaces Legacy Weakness: Silicon carbide bookings are a clear bright spot, but core semi equipment remains in a cyclical trough, and operational execution must improve for the company to fully capitalize as demand recovers.
• Execution and Cash Remain Watchpoints: Investors should monitor further ERP progress, working capital discipline, and the pace of backlog conversion, as these will determine the speed of margin and cash flow recovery.
• Cycle Turn is Key for Re-rating: Sustained improvement in advanced packaging and S&T demand, coupled with clean execution, will be necessary for Amtech to deliver on its secular growth promise.

Conclusion

Amtech’s Q3 2023 results reflect a company navigating both structural growth and near-term volatility. The silicon carbide business is outperforming, but operational discipline and semi cycle recovery will be crucial for realizing the company’s full value proposition.

Industry Read-Through

Amtech’s results reinforce the bifurcation within semiconductor capital equipment: suppliers exposed to silicon carbide and EV electrification are seeing robust demand, while traditional advanced packaging and S&T remain mired in a cyclical downturn. ERP implementation missteps are a cautionary tale for peers integrating acquisitions or upgrading legacy systems, as even small operational lapses can materially impact revenue recognition and cash flow. For the broader industry, the secular shift to silicon carbide and complex power electronics continues to accelerate, but capital equipment suppliers must balance growth investments with operational execution and liquidity discipline as the semi cycle remains volatile.
