Ultra Clean Holdings, Inc. Q3 FY2026 earnings call

• Strong Financial Execution: Delivered record revenue of $759 million, exceeding guidance highs. Bottom-line results outperformed expectations, with EPS of $1.15 and operating margin expanding to 9.0%.
• AI-Driven Demand Visibility: AI demand is shifting from training to everyday use, driving investment across the entire chip stack. Foundries are adding capacity on new nodes, while memory makers are expanding cleanroom space for DRAM and next-gen HBM.
• UCT 3.0 Strategy Implementation:
  • Ramp Readiness: Maintained capacity ahead of demand, evidenced by the early online status of 26,000 sq ft of cleanroom space in Malaysia.
  • NPX Co-Innovation: Secured eight new program wins across H, ALD, PVD, and lithography applications. Moving similar programs through development/qualification to capture high-value content per tool.
  • Digital Transformation: Launched an integrated planning platform linking demand, supply, inventory, and capacity in real-time to improve operational agility.
• Capacity Expansion: Expects to reach approximately $4 billion of annualized capacity in Q1. Plans to double development capacity in Cebu, Philippines, and add cleanroom capacity in Singapore and the Czech Republic. Vertical integrated manufacturing capacity in Malaysia and Thailand will double next year.
• Supply Chain Resilience: Proactively positioned with excessive capacity one to two quarters ahead of forecasts and built safety stocks. Did not miss a single module or subsystem shipment in Q3 despite industry-wide constraints.

• Semiconductor Products: Revenue of $681.9 million (up 19.1% sequentially), representing 86% of total revenue. Gross margin was 15.9%, up from 15.1% in Q2, driven by strength in etch and deposition subsystems for gate-all-around and high-bandwidth memory.
• Services: Revenue of $77.1 million (up 6.7% sequentially), representing 10% of total revenue. Gross margin was 30.1%, up from 28.9% in Q2. Growth is tied to wafer starts, with expectations for incremental increases as new U.S. fabs ramp through 2027 and 2028.
• Non-Semiconductor Markets: Represented the remaining 4% of total revenue.

• Q4 2026 Revenue Guidance: $800 million to $860 million, representing a 9.4% sequential increase at the midpoint.
• Q4 2026 EPS Guidance: $1.11 to $1.35 on approximately 48.9 million diluted shares.
• Long-Term Capacity & Investment: Path to $5+ billion capacity requires additional investment of roughly $80–$100 million incrementally through 2027 and 2028.
• Margin Outlook: Target of 20% gross margin at $4 billion revenue remains intact, driven by higher volume utilization, higher-value engineered products, increased vertical integration, and production in lower-cost regions.

• Supply Chain Excursions: Industry-wide pressure is causing component shortages, particularly in Mass Flow Controllers (MFCs). While UCT has mitigated this internally, broader ecosystem delays could impact customer system completion.
• Working Capital Intensity: Operating cash flow was negative $42.3 million due to working capital requirements for pre-ordering critical components and maintaining elevated safety stock levels to ensure timely delivery.
• Inventory Buildup: Inventory increased by $93.4 million to $723.3 million. While necessary for resilience, this ties up capital and carries risk if demand shifts unexpectedly.
• Execution Risk on Expansion: Rapid capacity expansion and digital transformation initiatives carry execution risks; capacity expansions may temporarily act as headwinds to margins as new phases come online.

Q: Timothy Arcuri (UBS) asked how UCT ensures share gain and stickiness given the massive capital investment in capacity expansion beyond $5 billion. He questioned if there are formal agreements or assurances with customers in exchange for this investment.

A: James Zhao explained that the industry is seeking long-term agreements starting from the end-customer level. UCT engages in open, constructive discussions with key customers to share future forecasts and demands early. This ensures that newly added capacity is fully utilized by these key partners, creating a resilient supply chain relationship rather than relying solely on transactional contracts.

Q: Charles Shi (Needham) inquired about specific supply chain excursions, particularly the rumored shortage of Mass Flow Controllers (MFCs). He asked how UCT, which does not manufacture MFCs, navigates this constraint and when suppliers expect balance.

A: James Zhao stated that MFC constraints may persist for one to two quarters but will be addressed collectively by the industry. UCT manages this through proactive positioning with excessive capacity and safety stocks, ensuring they did not miss any shipments in Q3. He emphasized that close collaboration with both customers and suppliers is key to smoothing these challenges, though no specific timeline for MFC balance was provided.

Q: Robert Mertens (TD Cowen) asked about the value of co-innovation versus pure manufacturing flexibility. He wanted to know where customized approaches add the most value and how UCT weighs engineering engagement against scaling production.

A: James Zhao highlighted the launch of a Center of Excellence for MPIs (Multi-Product Integration) in Hillsboro, leveraging Edge GIS capabilities. This allows UCT to co-work on new product development, securing eight new programs aligned with customer roadmaps for the next 2-3 years. This approach improves stickiness, margins, and share by moving from 'build-to-print' to 'build-to-spec,' integrating earlier in the design phase.

Q: Edward Young (Oppenheimer) asked if delays from other suppliers in the ecosystem could prevent customers from completing systems, thereby indirectly affecting UCT's performance, even if UCT itself delivers on time.

A: Mike Keogh and James Zhao confirmed that UCT was not gated by anything last quarter and missed zero shipments. They have been buying ahead to ensure strategic supply is met. While they acknowledge ongoing supply chain pressure and diligence is required, they currently feel well-positioned and do not see external supplier failures impacting their ability to ship.
