Brian Chin of Stifel Financial Corp. asked if KLA's advanced packaging opportunity is still primarily in 2.5D packaging and whether the focus is more on inspection or metrology applications.

Answer

EVP & CFO Bren Higgins confirmed that most of the share gains to date have been in the logic area with CoWoS (2.5D), but noted that momentum is increasing in HBM. He clarified that the opportunity is currently more 'defect loaded' than metrology, as the larger design rules in packaging limit some metrology applications, while the high cost of failure drives incredibly high sampling rates for inspection to avoid missing defects.

Brian Chin of Stifel Financial Corp. asked if KLA's near-term advanced packaging opportunity is concentrated more in 2.5D packaging than HBM, and whether the opportunity is primarily in inspection versus metrology.

Answer

EVP & CFO Bren Higgins confirmed that most share gains to date have been in logic-based CoWoS (2.5D) packaging, though momentum in HBM is increasing. He also affirmed the opportunity is more 'defect loaded,' meaning inspection-heavy, because the high cost of failure drives very high inspection sampling rates, while larger design rules in packaging currently limit some metrology applications.

Brian Chin from Stifel Financial Corp. inquired about the level of R&D spending from leading-edge logic customers not expanding capacity and asked about the expected process control intensity change moving to the 16A node.

Answer

CEO Richard Wallace indicated that spending from these customers was 'derisked' in the 2025 plan, implying minimal contribution. CFO Bren Higgins noted it was too early to model 16A intensity but said underlying trends are favorable. Wallace added that new solutions are sometimes 'back-ported' to older nodes, increasing their intensity, which is a positive dynamic for KLA.

Brian Chin asked about the weighting of the AI accelerator business in the second half and Q4 of this year, and if AI accelerator revenue significantly exceeded expectations entering the year. He also inquired about industrial robotics, asking if Q4 is expected to show positive seasonality (QoQ) or approach flat on a year-over-year basis. For System Level Test (SLT), he asked if it's common to win an insertion towards the back end of the test queue or multiple subsequent insertions for a given accelerator chip.

Answer

CEO Greg Smith confirmed that compute (VIP and networking) revenue was stronger than expected, while mobile, auto, and industrial were weaker, with memory strengthening but less significantly than compute. For SLT, Mr. Smith stated there's an incumbency advantage once designed in for an AI accelerator due to upgradeability for subsequent part generations. CFO Sanjay Mehta expects a seasonal uplift for robotics in Q4 (QoQ increase) despite a weaker automation market, with Mr. Smith adding caution due to the high-turns nature of the business.

Brian Chin asked about the weighting of the AI accelerator business in the second half and Q4 2025, and if its revenue significantly exceeded initial expectations. He also inquired about expected seasonality for industrial robotics in Q4 and Q1, and the commonality of winning multiple subsequent insertions for SLT in accelerator chips.

Answer

CEO Greg Smith confirmed that AI accelerator revenue (compute, networking) was significantly higher than expected at the beginning of the year, offsetting weaker mobile and auto/industrial segments. For SLT, Mr. Smith stated that once designed in for an AI accelerator, there is an incumbency advantage due to the system's upgradeability. CFO Sanjay Mehta expects a seasonal uplift for robotics from Q3 to Q4, acknowledging the ongoing strategic shift and weaker automation market. Mr. Smith added that robotics revenue prediction is challenging due to its high-turns nature.

Brian Chin of Stifel asked for an updated sizing of the overall compute TAM and the VIP sub-segment for the current year, and whether Teradyne expects to maintain its 50% share in VIP. He also questioned if the recent uptick in test utilization rates was attributable to any supply chain pull-forward activity.

Answer

President & CEO Greg Smith stated that the VIP TAM is tough to call for 2025 due to Q4/Q1 bridging, but agreed there is upward pressure on previous estimates. He confirmed networking is an important and strengthening part of their 2025 compute revenue. He also noted that while customers may have pulled forward demand, it primarily increased utilization rather than driving significant new capacity buys for Teradyne.

Brian Chin sought clarification on whether the VIP TAM forecast from the Analyst Day included SLT and asked about the potential timing and impact of onshoring advanced back-end test and packaging facilities to the United States.

Answer

CEO Greg Smith confirmed the VIP TAM figures were for semiconductor ATE and did not include SLT, which he estimated could represent an additional 10-30% of that TAM. Regarding onshoring, he explained that while ship-to locations may change, the total demand for testers is driven by end-market chip volume, not manufacturing location, so the overall impact on Teradyne's business should be minimal.

Brian Chin requested the SOC test market size for 2024 and the end-market breakdown for the 2025 TAM. He also asked about current test cell utilization rates and the specifics of the robotics go-to-market consolidation.

Answer

CFO Sanjay Mehta provided the TAM breakdowns: $4.6B in 2024 and a projected $4.9B in 2025, detailing the compute, mobile, and auto/industrial components. CEO Greg Smith estimated that test utilization rose about 10% year-over-year in 2024 and that the business has passed a tipping point toward system sales over upgrades. He explained the robotics consolidation combines the sales, marketing, and service functions of UR and MiR into a single organization.

Brian Chin asked for the reason behind the upward revision to the industrial test TAM, a quantification of the mobile installed tester base that has been repurposed for other markets like AI, and the key considerations driving the VIP compute TAM opportunity for next year.

Answer

CEO Greg Smith confirmed the industrial TAM revision was due to better visibility into the market in China served by local suppliers. He quantified that over 100 testers have been repurposed to date, with over 200 expected by year-end, leading to higher utilization. For the VIP TAM, he noted the 2024 estimate of $300M was a positive surprise, putting upward pressure on the 2026 target of $500M, but cautioned the market is lumpy and constrained by HBM and advanced packaging availability.

Brian Chin asked for a rough partitioning of the $8 billion WFE spending for AI across advanced logic, DRAM, and NAND. He also questioned whether the $40 billion NAND upgrade TAM needs to be fully exhausted before capacity spending occurs, or if these two types of investments can be somewhat concurrent.

Answer

Doug Bettinger, Executive Vice President and CFO, stated that more than half of the $8 billion WFE for AI comes from memory (enterprise SSDs and HBM). Tim Archer, President and CEO, explained that the timing of NAND upgrades versus capacity spending is customer-by-customer, with some concurrency possible, especially towards the back end of the upgrade rollout. However, upgrades are generally prioritized as the fastest and lowest-cost means.

Brian Chin asked for a rough percentage-based partitioning of the $8 billion WFE spending (derived from $100 billion in AI investment) across advanced logic, DRAM, and NAND. He also inquired whether the industry needs to fully exhaust the $40 billion NAND upgrade TAM before capacity spending begins, or if these two types of investments could occur concurrently.

Answer

EVP and CFO Doug Bettinger stated that more than half of the $8 billion WFE is expected to come from memory (enterprise SSDs and high-bandwidth memory). President and CEO Tim Archer explained that the progression from NAND upgrades to capacity spending would be customer-specific. While upgrades are generally prioritized as the fastest and lowest-cost method, some capacity additions are already occurring, and concurrence between upgrades and new capacity builds is expected, particularly towards the latter part of the upgrade rollout.

For Data Center, Kelley confirmed that AI is accelerating refresh cycles, which enhances the value of Advanced Energy's power density, efficiency, and reliability.

Brian Chin asked for details on the Q2 gross margin miss, the cause of the hiring and retention issues, the reason for the OpEx uptick, and the outlook for the second half of the year. He also sought clarification on the new flow control qualification and which end market was affected by a customer push-out.

Answer

CEO Jeffrey Andreson explained that gross margins were impacted by hiring and retention challenges for off-shift, clean-room positions in their Minnesota facility, which limited the output of machined components. He clarified the OpEx increase was due to higher healthcare costs, not hiring. Andreson projected a very slight, low-single-digit decline in revenue for the second half, attributing it to timing, and confirmed the flow control qualification is for advanced logic applications.

Brian Chin asked for details on the revised annual revenue outlook, questioning which semiconductor segments were driving the change, and followed up on the Q1 gross margin miss, inquiring about the execution level of internal sourcing and the progress into Q2.

Answer

Executive Jeffrey Andreson explained the revenue outlook change was driven by softness in lithography, non-semi business, and silicon carbide, not core deposition and etch. Regarding gross margins, he attributed the miss to "growing pains" in managing inventory for internally sourced components, stating they achieved about 75-80% of the plan but had to buy more external supply than forecasted. He expressed confidence that the strategy is working and the trajectory will improve.

Brian Chin inquired about the revenue outlook for the remainder of 2025, questioning if the pull-forward of labor costs implied a more bullish view than stated. He also asked about the potential gross margin impact if revenue upside came from legacy gas panels.

Answer

Executive Jeffrey Andreson clarified that they anticipate Q2 revenue to be similar to Q1, with a modest increase in the second half. He explained that the resource additions are largely to support the internal ramp of proprietary components, which is outgrowing other revenue streams. Andreson added that while a heavier mix of legacy gas panels could slightly mute margin percentage, improved overhead absorption and the tailwind from new internal supply should effectively offset that mix issue.

Brian Chin followed up on the NAND recovery, asking if it was alleviating customer inventory overhangs. He also questioned if the flat Q1 2025 revenue outlook was mainly due to a step-down in China WFE and sought confirmation on the 25% incremental gross margin target for 2025.

Answer

Executive Jeffrey Andreson explained that for gas panels, there is no lag from NAND demand, but a slight lag may persist for components like weldments. He attributed the flat Q1 outlook more to a rebalancing in lithography and muted silicon carbide demand than just China. Executive Greg Swyt confirmed that modeling at least a 25% incremental gross margin flow-through for 2025 is appropriate.

Brian Chin of Stifel Financial Corp. asked for details on the $28 million order, including its quarterly timing and market drivers.
