Will MKSI's FY2026 chemistry revenue grow at least 10% YoY ex-FX and palladium?

Chemistry revenue grew 11% in FY2025 ex-FX/palladium. The installed base of equipment is growing rapidly (chemistry equipment nearly doubled in FY2025), and the 18-24 month lag means FY2025 equipment shipments drive 2027 consumable revenue. But the question is about FY2026, which is driven by equipment installed in FY2024. AI chemistry growth (5% to 10% of E&P) provides an additional vector. The flywheel thesis and secular AI packaging trend support continued 10%+ growth, though the comparison base is now higher.

The 10% threshold is at the current run rate (FY2025 was 11%). Sustaining 10%+ requires the installed equipment base to continue generating incremental consumable revenue. Key risk: if semiconductor utilization rates drop (downturn scenario), even installed equipment generates less chemistry revenue. The committee noted chemistry revenue is utilization-dependent, not purely installed-base dependent. But absent a severe downturn, the math supports 10%+.

The strongest argument for 10%+ growth is the sheer volume of new equipment installed in FY2024-2025. Chemistry equipment nearly doubled in FY2025, and each $100M generates $20-40M/year in consumables. Even with some demand moderation, the installed base growth alone should drive 8-12% consumable growth. AI chemistry doubling from 5% to 10% in one year adds a powerful secular component. I lean higher probability because the flywheel has demonstrated momentum.

FY2025 chemistry growth was 11% and the drivers are strengthening (AI packaging complexity, growing installed base, record equipment shipments). The 10% threshold is below the recent run rate. Main risks are FX headwinds, semiconductor utilization softness, and the comparison base effect. On balance, momentum and structural drivers favor achieving 10%+.

The chemistry flywheel is the most validated part of the MKSI thesis. Three lenses independently confirmed it. Record equipment shipments mean the installed base is growing faster than at any point in history. AI chemistry growing from 5% to 10% provides a powerful incremental driver. FX is a wildcard but the question specifies ex-FX/palladium. I give moderate-to-high probability because the 10% threshold is at or below recent trajectory.

I temper enthusiasm slightly. The committee classified REVENUE_DURABILITY as CONDITIONAL, meaning the chemistry revenue growth is dependent on the broader semiconductor ecosystem health. If WFE disappoints, chemistry utilization could soften. 10% is still achievable in a moderate scenario but not certain if the cycle turns. The base case is 8-12% growth, putting 10% near the center of the range.

Chemistry revenue momentum is strong at 11% FY2025. Installed base growing from record equipment shipments. AI packaging secular trend supports continued growth. 10% threshold appears achievable.

10% growth is achievable but requires semiconductor utilization to hold. Downturn risk could reduce chemistry demand. Slightly above coin flip given positive momentum.

The chemistry flywheel has the strongest evidence backing of any MKSI thesis element. Three lenses confirmed it. Record FY2025 equipment creates FY2026-2028 consumable revenue. 10%+ growth is the central case.
