Tom Diffely inquired about the strength and improvements Kulicke & Soffa is observing in the NAND market, noting that this contrasts with broader industry discussions. He also asked if the company anticipates a typical post-Chinese New Year ramp in incoming new orders, despite expectations of less seasonality.

Answer

Lester Wong, Interim CEO and CFO, highlighted very high utilization rates in memory, exceeding 80%, and increasing purchase orders, particularly in China where utilization is near 90%. Regarding seasonality, Mr. Wong mentioned already seeing orders into Q2 and expects fiscal year 2026 to exhibit more linearity throughout the year, not anticipating a significant uptick after Chinese New Year.

Tom Diffely from D.A. Davidson Companies inquired about the current utilization rates at core customers and the key drivers for the sequential growth forecasted for the fiscal fourth quarter.

Tom Diffely asked whether the increase in the Arizona facility investment to $7 billion was primarily due to added capacity or rising construction costs. He also inquired about the specific portion of the $950 million 2025 CapEx forecast allocated to the Arizona campus.

Answer

CEO Giel Rutten clarified that the increased investment was exclusively related to planned capacity expansion, including twice the land area and an option for a third facility, and was not due to higher construction costs. CFO Megan Faust stated that the increase in the 2025 CapEx guidance to $950 million was driven by more visibility for 2025 spend, specifically for Arizona, with more details on 2026 CapEx and Arizona timing to be provided at the next earnings call.

He clarified that the consolidation in Japan targets mature products, driven by local market difficulties. Regarding the power segment, he noted that while the silicon carbide market growth has moderated from very high expectations due to the EV market, the long-term fundamentals remain strong, and Amkor's investments, like the facility in Portugal, are proceeding.

Tom Diffely inquired about the expected revenue mix for the fourth quarter, the direct and indirect impacts of tariffs and trade restrictions on operations, the target customers for the new high-end multi-beam writer, and any regulatory hurdles for expanding to 6-8 nanometer node production in Asia.

Answer

CFO Eric Rivera confirmed that the Q4 revenue mix would be similar to Q3. He explained that trade restrictions primarily impact customers but also affect Photronics through tariffs on material purchases from regions like Japan. Rivera clarified that the multi-beam writer serves high-end node customers like Samsung and that the planned 6-8nm expansion in Asia would occur in a non-China location, such as Taiwan or Korea, thus avoiding specific restrictions.

Tom Diffely of D.A. Davidson & Co. asked for details on the mainstream business, including the causes of its continued softness, the current supply-demand balance for mask making capacity, and the impact on margins and capital spending. He also inquired about the geographic nature of the weakness, the year-over-year earnings drivers, and the initial priorities for newly appointed CEO George Macricostas.

Answer

CEO Frank Lee attributed mainstream weakness to low wafer fab utilization among customers in the power, industrial, and consumer sectors, but noted that long-term agreements help stabilize pricing. CTO Christopher Progler added that while end-of-life tool replacements initially constrained supply, new capacity has since been added globally, creating a temporarily unfavorable supply-demand balance amid muted demand. He clarified the weakness is broad-based, not confined to Asia. CFO Eric Rivera mentioned the company is using product mix to offset pricing pressure. Incoming CEO George Macricostas stated his initial focus will be on learning the Asia operations from Frank Lee and managing administrative functions, while pursuing a dual strategy of cost containment and market share growth.
