Question · Q4 2025

Elizabeth Sun asked about AI's percentage of Entegris's total revenue, given it's 5% of wafer starts but Entegris has higher content for AI-related products. She also inquired about expectations for advanced packaging revenue in 2026, noting its smaller but growing contribution, POR wins, and HBM efforts.

Answer

CEO Dave Reeder stated that approximately 60% of Entegris's 2025 revenue came from advanced nodes (logic 7nm and below, and the last two generations of memory), which is expected to grow as AI drives demand for incremental capacity and memory. For advanced packaging, Dave noted it grew nicely in 2025 (around $100 million+) and is expected to continue growing in 2026. He mentioned product lines are sampling now, with others to follow later in the year, and while more significant benefits are anticipated in 2027 and beyond, it is a growing, complex market that aligns well with Entegris's product portfolio.

Elizabeth Sun's questions to FORMFACTOR (FORM) leadership

Question · Q4 2025

Elizabeth Sun inquired about the outlook for the Foundry and Logic market this year, considering both the upside from networking and potential GPU qualification, and the softness in traditional markets like smartphones and PCs. She also asked for clarification on the target model gross margin of 47%, specifically whether it includes the 200 basis points tariff impact, and inquired about the mitigation methods being implemented for tariffs and potential upside from these efforts.

Answer

CEO Mike Slessor stated that FormFactor expects the Foundry and Logic market to grow overall, with the company aiming to gain share, highlighting the successful shift towards high-performance compute (e.g., networking switches) and the achievement of record revenue without the large microprocessor IDM being a 10% customer as testament to this diversification. Senior VP Aric McKinnis clarified that the 47% target model gross margin does not include tariffs, so the adjusted target is 45% with the 200 basis point tariff headwind. He explained that the primary mitigation path is pursuing "drawbacks" with the customs department to reclaim paid tariffs, but noted it's a detailed, time-intensive process that could take several quarters to show P&L benefits.
