Setting the Stage: A Semiconductor Assembly Leader Responds to Evolving Demands

Kulicke & Soffa Industries, Inc. (KLIC) has long stood as a foundational player in the semiconductor assembly equipment market. Founded on innovation in 1951, the company built its legacy on providing essential tools and services for packaging semiconductor devices, primarily through its dominant Ball Bonding and Wedge Bonding technologies. This historical strength in high-volume, cost-sensitive assembly processes, coupled with a robust Aftermarket Products and Services (APS) segment, has provided a stable, albeit cyclical, business base. Over the decades, KLIC demonstrated an inherent competency in critical material transitions, notably leading the shift from gold to copper wire bonding, a testament to its deep engineering expertise.

Today, the semiconductor landscape is undergoing a profound transformation. As traditional node scaling becomes increasingly complex and expensive, the industry is turning to advanced packaging techniques – multi-die integration, heterogeneous assembly, and chiplets – to continue driving performance improvements and transistor density at the package level. This shift presents both challenges and significant opportunities for assembly equipment providers. Recognizing this evolution, KLIC has strategically expanded its focus beyond its core wire bonding strengths to become a key enabler of these next-generation packaging technologies, particularly in Thermo-Compression Bonding (TCB) and Advanced Dispense.

This strategic pivot is not merely an expansion but a deliberate refinement of the company's business model. Facing a prolonged market downturn that has seen revenue levels significantly below historical norms, KLIC recently announced the intended cessation of its Electronics Assembly (EA) equipment business. Acquired in 2015, the EA segment, while contributing to the "All Others" category, was deemed less aligned with the company's core semiconductor assembly priorities and long-term technology trends. This difficult decision, expected to be substantially completed by the first half of fiscal 2026, aims to streamline operations, prioritize higher-growth opportunities, and enhance overall through-cycle financial performance. This move, coupled with the resolution of the Project W advanced display project cancellation (resulting in a significant customer reimbursement in Q1 FY25), underscores management's proactive approach to optimizing the business for the future.

The core investment thesis for KLIC today rests on its ability to leverage its established market leadership and operational resilience through the current cyclical trough while simultaneously capitalizing on secular growth drivers in advanced packaging and power semiconductors through differentiated technology. The success of this strategy hinges on driving customer adoption of its innovative solutions and navigating the persistent macroeconomic and geopolitical uncertainties that continue to impact the industry.

Technological Edge: Enabling the Future of Packaging

KLIC's competitive strength is increasingly defined by its technological differentiation, particularly in the burgeoning field of advanced packaging. While its core Ball and Wedge bonding technologies remain critical for high-volume applications, the company's investments in new areas are opening doors to previously inaccessible markets.

A cornerstone of this strategy is the company's leadership in Fluxless Thermo-Compression Bonding (FTC). KLIC is the first and only provider of Fluxless TCB systems proven in a production environment. This technology offers significant advantages over traditional TCB methods, enabling direct copper-to-copper interconnects with zero die gap and ultra-fine pitch capabilities. These features are crucial for the demanding requirements of high-performance computing (HPC), artificial intelligence (AI) accelerators, and future mobility applications utilizing chiplet architectures. The company's FTC system architecture, embodied in platforms like APTURA™, is designed for flexibility, supporting a wide range of packaging formats including chip-to-chip and chip-to-wafer bonding. KLIC has demonstrated its FTC capability for a chip-to-wafer hybrid bonding process, offering a potentially lower capital-intensive path to hybrid-based chiplet assembly compared to solutions requiring extensive front-end investments. While precise, directly comparable quantitative performance metrics (e.g., specific throughput advantages over all competitors) are not publicly detailed for all applications, management highlights that their dual-head TCB tool with TwinNet aims for advantages or slight improvements in throughput and productivity for HBM applications compared to current competition, emphasizing performance and availability for better productivity. The company's TCB installed base of nearly 120 systems across 10 engaged customers captures a wider portion of the market than many competitors, providing a strong foundation for future growth.

Beyond TCB, KLIC is making strides with its Vertical Wire technology. This innovative approach is specifically designed to address the increasing demand for stacked-die solutions in high-volume markets like memory (DRAM and NAND) and potentially future stacked logic applications. Vertical wire bonding offers benefits such as smaller package footprints (e.g., reducing form factor by about 30% for LPDDR5 applications), improved die layout, lower parasitic capacitance, and lower parasitic resistance compared to traditional wire bonding or even some emerging hybrid bonding methods that can be prohibitively expensive. KLIC is actively engaged with leading memory customers in Korea, the U.S., and China on Vertical Wire, with initial low-volume production anticipated in fiscal 2025 and a significant ramp expected in 2026 and beyond.

In the Power Semiconductor market, KLIC is leveraging its Wedge bonding expertise and developing new solutions like High Power Interconnect (HPI). As electric vehicles (EVs) and sustainable energy applications drive demand for higher-current, higher-reliability, and higher-efficiency power devices, the need for more robust interconnects grows. KLIC's new Asterion-PW system for pin welding, leveraging the Asterion platform, extends its reach in this evolving market, supporting the increasing use of pins and copper materials. Copper interconnects, a core competency for KLIC, are becoming more prevalent in high-performance power modules. HPI is already being deployed in volume battery production and for efficient power conversion.

Furthermore, the Advanced Dispense business is building out its portfolio, recently securing an order from a high-volume U.S.-based IDM and seeing progress with a solid-state EV battery manufacturer, with a potential production ramp anticipated. This expands KLIC's footprint in battery-related opportunities and diversifies its dispense market presence.

These technological advancements are not isolated efforts but interconnected pieces of KLIC's strategy to address the diverse needs of the evolving semiconductor assembly market, from leading-edge chiplets to high-volume stacked memory and power applications.

Strategic Evolution and Segment Performance

KLIC's strategic pivot is clearly reflected in its recent segment performance and forward focus. The decision to discontinue the EA equipment business, while resulting in significant one-time charges ($86.6 million in Q2 FY25, including a $28.9 million inventory write-down and $39.8 million in asset/goodwill impairment), is intended to streamline the portfolio and enhance profitability. The EA business historically contributed a relatively small portion of revenue ($25M-$30M annually) with lower gross margins ($7M-$11M) and operating losses ($20M-$25M operating expense), suggesting its exit should be accretive to overall margins and through-cycle performance once completed.

Looking at the core reportable segments:

• Ball Bonding Equipment: This segment remains KLIC's largest revenue contributor, accounting for 38.4% of net revenue in the six months ended March 29, 2025 ($125.97 million). Revenue decreased by 25.1% year-over-year in H1 FY25, primarily due to lower volume in general semiconductor and memory markets. However, the gross profit margin improved to 49.5% in H1 FY25 (from 47.4%), driven by favorable customer mix. Management notes improving utilization rates, particularly in China (>80%), suggesting a potential trigger for capacity buys, although broader adoption is delayed by macro uncertainty.
• Wedge Bonding Equipment: This segment saw significant growth, with revenue increasing by 48.0% to $68.42 million in H1 FY25, representing 20.9% of total revenue. This growth was primarily driven by higher volume in general semiconductor and automotive markets, linked to EV adoption. Despite the revenue growth, the gross profit margin decreased to 44.5% (from 50.8%), mainly due to a less favorable product and customer mix. Management is optimistic about continued recovery in automotive/industrial driving Wedge demand.
• Advanced Solutions: This segment, which includes TCB and certain advanced display/die-attach, saw revenue more than double to $45.82 million in H1 FY25 (14.0% of total revenue). The significant increase was primarily due to higher volume in general semiconductor markets and the impact of prior year inventory write-downs related to Project W. Gross profit margin was exceptionally high at 70.2% in H1 FY25, heavily influenced by the Project W settlement gain recognized in Q1 FY25. Excluding discrete items, the segment reflects the growing momentum in TCB and other advanced solutions.
• Aftermarket Products and Services (APS): This segment provides a more stable revenue base, contributing 23.4% of total revenue ($76.91 million) in H1 FY25. Revenue decreased by 6.1% year-over-year, mainly due to lower volume in spares and services and unfavorable pricing from bonding tools. Gross profit margin also declined to 51.1% (from 55.6%). Management anticipates this segment will remain relatively stable, supported by improving installed base utilization.
  
  Consolidated revenue for the six months ended March 29, 2025, was $328.11 million, a decrease of 4.4% from the prior year period. Gross profit increased by 32.3% to $127.47 million, with the gross margin expanding significantly to 38.8% (from 28.1%), largely influenced by the Project W settlement and EA inventory write-down impacts. Operating expenses decreased by 37.2% to $125.49 million, primarily due to the $75.99 million gain relating to the cessation of business (Project W reimbursement, subsidiary disposal, supplier settlement) in FY25, partially offset by higher SGA and R&D costs. This resulted in income from operations of $1.98 million in H1 FY25, a substantial improvement from a loss of $103.46 million in the prior year period, which included the $44.47 million Project W impairment charge. The net loss for H1 FY25 was $2.88 million, or $0.05 per diluted share, compared to a net loss of $93.39 million, or $1.66 per diluted share, in H1 FY24.

Competitive Landscape and Positioning

KLIC operates in a competitive semiconductor capital equipment market alongside larger, more diversified players like ASML (ASML), KLA (KLAC), Applied Materials (AMAT), and Lam Research (LRCX), as well as other specialized assembly equipment providers.

Outlook and Future Prospects

Management's outlook reflects cautious optimism amidst ongoing market volatility. The guidance for Q3 FY25 (June quarter) anticipates revenue of $145 million, plus or minus $10 million, with gross margins of 46.5%. This sequential decline from Q2 FY25 ($162.0 million) is primarily attributed to near-term order hesitation and defensive capacity planning, particularly impacting the Southeast Asia Automotive and Industrial market. Non-GAAP operating expenses are guided at $68 million, plus or minus 2%, with a GAAP EPS loss of $0.09 and non-GAAP EPS gain of $0.05 per share.

Looking beyond Q3 FY25, management anticipates a stronger second half of fiscal 2025. This expectation is supported by improving utilization rates in core markets (China >80%, Taiwan ~80%, rest of world in high 70s), which are nearing levels that typically trigger broader capacity additions. While customers are currently delaying non-critical CapEx due to uncertainty, the underlying demand drivers remain. Semiconductor unit growth is expected to improve through fiscal 2025, with updated forecasts suggesting growth a little greater than 10% in calendar 2025, driven by AI, automotive, and general semiconductor markets.

KLIC expects an eventual return to incremental capacity growth in core Ball and Wedge bonding markets, potentially reaching pre-COVID normalized annual revenue levels of $500 million to $600 million for Ball Bonders by late fiscal 2025 or early fiscal 2026. Fiscal 2026 is anticipated to be a more normalized year.

Growth in advanced packaging is expected to continue, supplementing core market recovery. The TCB business is projected to grow from approximately $70 million in FY25 to $100 million or more in FY26. Vertical Wire revenue, while below $20 million in FY25, is targeted at $50 million in 2026 and is expected to take off significantly in 2027. Advanced packaging revenue overall (including TCB, Vertical Wire, etc.) is forecasted to be close to $200 million in FY25, with a target of $275 million to $300 million for calendar year 2025.

Key factors to watch include the timing and strength of the broader semiconductor market recovery, the impact of geopolitical developments on trade and customer CapEx decisions, and the successful execution and market adoption of KLIC's new advanced packaging solutions.
