Q&A:

• Question from Steve Barger (KeyBank Capital Markets): Can you update us on what the NAND tool upgrade cycle looks like and how that bridges to Greenfield projects you may see entering equipment planning?
  Response: Upgrade activity is continuing and lumpy; the industry is increasing NAND capacity, with Greenfield NAND fab announcements expected towards end of 2027/beginning of 2028.

• Question from Steve Barger (KeyBank Capital Markets): Can you compare the magnitude of dollar spend for a new leading edge tool versus an upgrade?
  Response: The RF power part of an upgrade is the largest cost/opportunity; for a new tool, the power content is large, but the entire semiconductor portfolio benefits.

• Question from Steve Barger (KeyBank Capital Markets): Can you talk about lead times and visibility into 2027 on the semi side?
  Response: Customers have provided plans further out than normal; lead times are still kind of normal, and MKS is building capacity and inventory to meet anticipated demand increases.

• Question from an unnamed analyst (likely from a firm): Can you give an update around the ramp-up of the Malaysia and Thailand capacities and are you still comfortable with the $180 to $200B WFE support range?
  Response: Malaysia has started ramping (first revenue shipments); capacity planning has been reconfigured so that when Penang is filled out, it can support a WFE range of $200 to $250B, an improvement from last quarter.

• Question from an unnamed analyst (likely from a firm): Can you touch on some of the end markets or sectors that are helping in the specialty industrial platform and discuss its durability and baseline into next year?
  Response: Strength is driven by Datacom (AI-related) and defense; these are expected to continue strong. Automotive is steady, and industrials show incremental improvement.

• Question from Matt (likely from a firm): How should we be thinking about the chemistry growth potential moving forward given continued equipment strength? Any update on AI contribution as a percentage of those revenues?
  Response: AI contribution in chemistry is now 15-20% of total chemistry revenue. Equipment ASPs are higher due to AI demand, which affects the chemistry attach rate (20-40% range, now at the lower end mathematically).

• Question from Matt (likely from a firm): Can you give updated thoughts on strategy around deleveraging and at what point do voluntary payments begin to move more meaningfully higher?
  Response: Investing in organic growth is the first priority, followed closely by deleveraging. $100M prepayments are made each quarter, with additional payments planned for Q3 and Q4.

• Question from Michael (likely from a firm): Could you give an update on the mix of NAND vs DRAM vs Logic in the semi-market and how it may evolve?
  Response: The semi-market is still largely logic and DRAM-driven, with NAND upgrade activity. The Q3 semi revenue guide implies >50% year-over-year growth, with depth etch growing much faster than the average.

• Question from Michael (likely from a firm): Could you help decompose E&P strength between chemistry vs electroplating vs flex drilling and comment on demand destruction fears related to mobile?
  Response: Demand destruction fears are more benign than feared. Flex drilling is strong in smartphones, while AI is driving chemistry growth. Chemistry equipment is shipping as fast as possible, with Germany factory now used to meet demand ahead of the new Guangzhou factory.

• Question from Shane (likely from a firm): Just how much of your quarter-over-quarter decline into September is a result of some E&P chemistry weakness, and are you expecting Palladium to be a tailwind or headwind?
  Response: The Q2 gross margin of 47.6% included ~100 bps from discrete items; excluding those, it was consistent with past quarters. Palladium is expected to stay flat at ~$1,300 in Q3. Investments for capacity and unfavorable mix (VSD and chemistry equipment ramp) are temporary headwinds to gross margin.

• Question from Shane (likely from a firm): Where are we in the margin recovery path for VST, and what is needed for margins to get above the 46-47% prior peak?
  Response: VSD margins are lower due to mix (not highest-end products), ongoing investments in labor/CapEx, and reduced China direct sales tailwind. Over time, volume and operational excellence should help, but it's a different cycle than before.

• Question from Melissa Weathers (DB): How are you thinking about 2027 growth rates? Which will grow faster between semis and E&P?
  Response: Both are at historic growth rates and are coupled (chip making requires packaging). It's hard to determine which will be higher, but they are dynamically linked.

• Question from Melissa Weathers (DB): Is there any change to how you guys are thinking about pricing?
  Response: Pricing strategy remains to be fairly paid, with continuous evaluation; no opportunistic short-term pricing changes planned to maintain long-term customer relationships.

• Question from Krish (likely from a firm): Is it fair to characterize semi-revenue growth as easily over 35% this year? What does that imply about inventory management by semi-cap customers?
  Response: Yes, semi-revenue growth is north of 35%, with depth etch growing faster. Inventory is rising due to high turns and meeting shipment demands, but there is no extra stocking; the industry is ramping to meet demand.

• Question from Krish (likely from a firm): Is chemistry growing despite substrate capacity constraints?
  Response: Chemistry revenue is expected to continue growing as customers utilize existing tools better and new equipment is installed, even with capacity constraints.

• Question from Vijay (likely from a firm): What is driving the acceleration into September in the semi-market?
  Response: Acceleration is driven by both depth etch and litho/metrology/inspection, growing at their normal expected rates, with depth etch growing much faster year-over-year.

• Question from Vijay (likely from a firm): How should we look at 2027 growth for semis and E&P versus WFE?
  Response: Acceleration is expected to continue into 2027; customer conversations indicate preparing for an accelerating environment, which would maintain outperformance of WFE during the ramp.

• Question from Jim (likely from a firm): Can you provide the chemistry growth in the quarter?
  Response: Chemistry grew 21% year-over-year; quarter-over-quarter growth was also healthy. Most growth is from previously installed capacity, though new equipment is contributing.

• Question from Jim (likely from a firm): When do you expect to see more chemistry revenue attached to equipment shipped in the past two years?
  Response: Chemistry revenue will ramp continuously over the next couple of years, with lead times of 24-30 months before volume chemistry appears from new equipment.

• Question from Joe (likely from a firm): Will EMP equipment capacity be constrained until the new Guangzhou facility opens in Q3 2027?
  Response: No, capacity is not constrained due to the Germany factory being brought back online and expanding space in Guangzhou; all orders are being met.

• Question from Joe (likely from a firm): What drove the strong services revenue this quarter?
  Response: High utilization of semiconductor customers' fabs, leading to increased equipment service needs, setting a new elevated level for service revenue.

• Question from Jim Schneider (Goldman Sachs): Can you talk about accounting for startup costs in the new factories and if those headwinds will abate?
  Response: Startup costs are charged to COGS, impacting gross margin by 50-80 bps per quarter for a few quarters; improvements will flow through as plants fully load.

• Question from Jim Schneider (Goldman Sachs): Do you expect pricing increases over the next 12-18 months to offset input cost pressure?
  Response: Yes, the company has successfully done this in the past by securing scalable suppliers and delivering valuable products customers are willing to pay for.
