Thank you, John, and good morning, everyone. We delivered strong results in the third quarter, driven by healthy demand in our semiconductor and electronics and packaging end markets and continued stability in our specialty industrial end market. As in prior quarters, our execution remains strong with healthy margins, robust free cash flow and continued progress on our deleveraging goals. Third quarter revenue was $988 million, up 2% sequentially and up 10% year-over-year. The result was at the high end of our guidance and reflected better-than-expected trends in key end markets. Third quarter semiconductor revenue was $415 million, down 4% sequentially, but up 10% year-over-year. This result was at the high end of our expectations. The sequential decline was driven by lower RF power sales due to the timing of NAND upgrade activity as expected. The year-over-year growth was driven by strength in many product categories, including our vacuum products and plasma and reactive gas businesses. The fundamentals of our semiconductor business remains strong. Third quarter Electronics and Packaging revenue was $289 million, up 9% sequentially, driven by growth in our chemistry and equipment businesses. On a year-over-year basis, sales were up 25%, driven by growth in chemistry, chemistry equipment and flexible PCB drilling equipment sales. These strong results underscore the strength of our Electronics and Packaging business as we deliver enabling technologies for high-growth emerging AI applications and today's advanced consumer electronics. Chemistry revenue was up 10% year-over-year, excluding the impact of FX and palladium pass-through, continuing the strong growth trend over the last year. In our specialty industrial market, third quarter revenue was $284 million, an increase of 3% sequentially, mainly due to the improvement in the industrial market. Revenue was down 1% on a year-over-year basis. Overall, our Specialty Industrial business has remained steady for well over a year. Third quarter gross margin was 46.6%, just above the midpoint of our guidance. Gross margin were stable relative to the prior quarter, with tariff impacts of about 80 basis points, 35 basis points better than last quarter, offset by a higher mix of chemistry equipment sales. As we have stated before, the strong equipment sales we have seen throughout 2025 are a good indicator of future high-margin chemistry revenues. Third quarter operating expenses were $256 million at the high end of our guidance and higher sequentially, primarily as a result of an increase in variable costs, mostly related to employee incentive compensation tied to stronger business performance. Third quarter operating income was $205 million with an operating margin of 20.8%. Third quarter adjusted EBITDA was $240 million and above the midpoint of our expectations with adjusted EBITDA margin of 24.3%. Net interest expenses was $45 million, in line with our guidance. Third quarter effective tax rate was 17.9%, just below the midpoint of our guidance. Third quarter net earnings were $130 million or $1.93 per diluted share and above the midpoint of our guidance. Free cash flow generation was very strong at $147 million, representing over 100% of our net earnings and 15% of our revenue. Through the first 3 quarters of 2025, we generated cumulative free cash flow of $405 million, nearly as much as we did in all of 2024. We invested $50 million in capital expenditure in the quarter. We expect CapEx to sequentially increase in Q4 but fall within the low end of our annual CapEx guidance of 4% to 5% of revenue. We closed the quarter with approximately $1.4 billion of liquidity comprised of cash and cash equivalents of $697 million and our undrawn revolving credit facility of $675 million. As John highlighted, we made a voluntary principal prepayment of $100 million in October. In total, we have made $400 million in voluntary payments thus far in 2025. We remain focused on executing our long-term capital allocation priorities of investing in organic growth opportunities while reducing our leverage through principal prepayments and working with our banking partners to reduce our interest expenses as market opportunities arise. We exited the quarter with a gross debt of $4.4 billion and a net leverage ratio of 3.9x based on our trailing 12-month adjusted EBITDA of $953 million. We continue to bring down our net leverage ratio as we generate strong free cash flow, make proactive principal prepayments and deliver high year-over-year adjusted EBITDA. Finally, during the quarter, we paid a dividend of $0.22 per share or $15 million. Let me now turn to our fourth quarter outlook. The guidance we are providing represents our best estimate based on the dynamic trade environment in which we are operating. We expect revenue of $990 million, plus or minus $40 million. By end market, we expect semiconductor revenue to be $415 million, plus or minus $15 million, reflecting the continued strong fundamentals of our business. Revenue from electronics and packaging market is expected to be $295 million, plus or minus $10 million, which would be up 16% year-over-year at midpoint. As we look to model 2026, we would remind you that chemistry equipment revenue is poised to have a record year in 2025 and has historically varied significantly from year-to-year. Chemistry revenue, which is the majority of our E&P revenue, is much steadier and more predictable. Revenue from our specialty industrial market is expected to remain relatively steady at $280 million, plus or minus $15 million. We are guiding gross margin of 46%, plus or minus 100 basis points. The sequential decline is due to higher chemistry equipment sales in the mix and lower chemistry sales due to seasonality, partially offset by lower tariff-related impacts. We anticipate our mitigation actions will nearly offset tariff costs dollar for dollar beginning in Q4; however, these costs are passed through at 0 margins, and we anticipate tariff will continue to dilute our gross margin in Q4 and moving forward by approximately 50 basis points. With our mitigation initiatives in place, we remain confident in our plan to deliver our long-term gross margin objective of 47% plus. We expect fourth quarter operating expense of $255 million, plus or minus $5 million. As a reminder, OpEx is typically higher in Q1 as a result of higher stock-based compensation and fringe benefits consistent with prior years. We expect fourth quarter adjusted EBITDA of $235 million, plus or minus $24 million. We expect tax rate of approximately 2% in the fourth quarter, benefiting from certain favorable discrete tax items in the quarter and bringing our full year tax rate to just over 14%. We expect fourth quarter net earnings per diluted share of $2.27, plus or minus $0.34. Wrapping up, MKS has executed at a high level through the third quarter, and we are expecting this momentum to continue in Q4. We are winning exciting opportunities across our semiconductor and electronics and packaging end markets, and we are focused on managing our business with discipline to drive profitability and free cash flow. We remain focused on reducing our leverage. With our broad portfolio of products, strong secular tailwinds and an improving balance sheet, MKS is in a great position as we look to 2026. With that, operator, please open the call for Q&A.
