Thematic Exposure -- 9.2/10
KLA dominates semiconductor process control and inspection with ~55% market share -- 6.5x
the size of the #2 player. Over the past 5 years, process control share of WFE has grown
~250bps, and KLA has expanded its share within process control as well. Every major trend in
semiconductor manufacturing -- AI-driven complexity, EUV scaling, HBM architecture, advanced
packaging, and custom silicon proliferation -- structurally increases the need for inspection
and metrology. CY2025 was a record year: process control systems revenue grew 19% and overall
KLA revenue grew 17%, both outpacing estimated WFE growth of mid-to-high single digits.

Process Control Monopoly
~55% Market Share -- 6.5x Larger Than #2 Competitor
KLA holds ~55% of the semiconductor process control market, making it 6.5x larger than the
nearest competitor. Process control share of WFE has grown ~250bps over the past 5 years,
reflecting the structural increase in inspection intensity at every new node. In CY2025,
KLA delivered record revenue of $12.7B (+17% YoY) while process control systems grew 19%,
both meaningfully outpacing estimated WFE growth of mid-to-high single digits. The monopoly
is protected by optical physics, precision engineering, and decades of customer process data
that create formidable barriers to entry.

1. AI / Advanced Node Complexity -- Rising Inspection Intensity
Process Control Intensity Rises at Every New Node
Every major trend in semiconductor manufacturing increases the need for process control:
larger die, more complex designs (gate-all-around), higher-value wafers, reduced redundancy,
and accelerating product cycles. Management noted that process control intensity continues to
rise at each new node, and KLA share at N2 is "meaningfully greater than what we saw at N3."
The proliferation of custom silicon from hyperscalers is creating a proliferation of new
higher-value design starts and increased demand for inspection. AI inference and training chips
require the most advanced nodes with the tightest tolerances, making process control a direct
beneficiary of the AI infrastructure buildout.

2. EUV Stochastics and Reticle Inspection
EUV Lithography Requires More Inspection Layers
EUV lithography requires more inspection layers, and its introduction into DRAM added ~100bps
of process control intensity. Reticle inspection is inflecting -- CY2025 was a record year for
reticle, driven by accelerating design starts and EUV print check requirements. The Gen 5 CTA
for print check is gaining traction among leading-edge customers. As EUV expands from
leading-edge logic into DRAM and potentially High-NA EUV arrives, the inspection requirements
compound further, creating a durable structural tailwind for KLA.

3. HBM / DRAM Process Control Intensity Revolution
~200bps Incremental Intensity -- Most Structurally Significant Shift
This is the most structurally significant shift in KLA thematic exposure. Historically, DRAM
process control intensity was 9-10% of WFE. With EUV insertion: +100bps. With HBM: another
+100bps. Total shift: ~200bps of incremental intensity. The drivers are fundamental: less
redundancy in HBM (customers cannot "bin" devices), bigger die with TSVs, more metallization
layers, more complex base die logic, and tighter reliability specs. Memory now represents 40%
of semi PC systems revenue vs. 18% just two years ago. Management stated: "DRAM is looking
much more similar to what logic did not that long ago." This is not cyclical memory spending
but a permanent elevation of process control requirements driven by HBM architecture.

4. Advanced Packaging Inspection -- New SAM
$950M CY2025 Revenue, +70% YoY -- Genuinely New Served Market
KLA generated $950M in advanced packaging revenue in CY2025, up 70%+ YoY. Process control
share of advanced packaging WFE went from ~1% in 2021 to ~6% in 2025, with KLA approaching
~50% share of process control in packaging. Management expects mid-to-high teens percentage
growth in CY2026. KLA has adapted front-end inspection tools for back-end packaging, pulled
in by customer demand. Sampling rates are high and rising. This is a genuinely new SAM that
augments core WFE growth and is driven by the same AI infrastructure buildout requiring
advanced packaging technologies like CoWoS.

5. E-Beam Inspection Momentum
Doubled Revenue in CY2024, +700bps Share Gain
KLA doubled e-beam inspection revenue in CY2024, gaining ~700bps of market share. E-beam
works in concert with optical inspection for the most challenging layers at leading-edge
nodes -- customers are adopting both modalities as complementary tools. Further capacity
additions are underway to meet demand. This inflection creates a new high-growth product
line that reinforces KLA dominance across the full inspection spectrum, from optical to
electron beam.

6. Services Flywheel
$786M CQ4 2025, 16 Consecutive Years of Growth, 12%+ CAGR
Services grew to
$786M in CQ4 2025,
up 18% YoY -- the 16th consecutive year of annual service revenue growth with a 12%+ CAGR.
Higher tool utilization (AI inference fabs run 24/7), a growing installed base, longer tool
lifetimes, and higher ASP tools all compound the recurring revenue stream. Contract
penetration is rising in memory as HBM reduces redundancy and demands higher uptime.
Management targets 12-14% long-term service growth and expects to operate at the higher end.
Services now represent ~25% of total revenue, providing meaningful countercyclical ballast.

Memory share rising sharply, driven by HBM and EUV adoption in DRAM. CQ1 2026 guided at 40% memory with DRAM 85% of memory. Structural shift, not cyclical.
Score Rationale
9.2/10 — Exceptional thematic
positioning across six reinforcing secular growth vectors. KLA holds a near-monopoly in
semiconductor process control with ~55% share (6.5x the #2 player), and every major trend in
chip manufacturing structurally increases inspection intensity. AI/advanced node complexity
drives rising process control requirements at each new node. EUV stochastics and reticle
inspection are inflecting. The HBM/DRAM intensity revolution represents a ~200bps permanent
elevation of process control requirements -- the most structurally significant shift. Advanced
packaging ($950M, +70% YoY) is a genuinely new SAM. E-beam inspection doubled revenue with
+700bps share gain. The services flywheel ($786M CQ4, 16 years of growth, 12%+ CAGR) provides
compounding recurring revenue and countercyclical ballast. The score does not reach 10 because
China export restrictions have removed $300-350M of revenue and further policy tightening
remains a tail risk, and the premium valuation (~43x forward) leaves limited room for
multiple expansion.
