## Key stats

- **Ticker:** KLAC
- **Market Cap:** $240B

## Moat

Near-monopoly (~58% process-control share in 2025, up 360bps since 2021) in semiconductor process control and wafer inspection — every advanced node ramp at TSMC, Samsung, and Intel runs through KLA tools. KLA holds the #1 position in process control for advanced wafer-level packaging, where FY2026 results put calendar-2026 revenue on track for ~$1.1B, growing at roughly twice the underlying market.

### The Yield-Learning Moat

KLA's moat is the **accumulated yield-learning data** from decades of inline wafer inspection — a proprietary defect-signature library that only deepens at each new process node:

- **Yield-Learning Data Compounds Per Node:** Every wafer inspected adds to KLA's defect-signature library. Customers can't replicate this dataset because it's accumulated across the entire industry. New nodes (3nm, 2nm, 1.4nm) extend the lead — defect modes get more subtle and require more inspection sophistication, not less. Process-control share has climbed to ~58%.
- **Inline at Every Wafer:** KLA process-control tools sit inline in fab production lines — every wafer at TSMC's leading-edge fabs passes through KLA inspection. The transaction-embedding moat is structural: pulling KLA tools requires re-architecting fab flow.
- **Advanced Packaging is the New Front:** HBM stacks and chiplet integration require an order of magnitude more process control than monolithic chips. Advanced-packaging process control has gone from $635M in calendar 2025 to a guided ~$1.1B in calendar 2026 — past the company's own $1B target, growing at about twice the market, in a TAM that effectively didn't exist 5 years ago.

**Moat verdict:** KLA is a clear net beneficiary of AI, and nothing in the FY2026 close moved a moat status. The strongest moats — proprietaryData (yield-learning library, ~58% process-control share), systemOfRecord (yield-management software), regulatoryLockIn (foundry certs + export controls), bundling, businessLogic — are all AI-strengthened or AI-neutral. The one AI-vulnerable moat (learnedInterfaces) is correctly downgraded because operator workflows are being automated. FY2026 evidence reinforces rather than changes the picture: a record $3.66B June quarter, ~$12.5B backlog, demand broadening past the single leading-edge customer, and advanced-packaging process control compounding at roughly twice its market. The 2030 framework (~$26B revenue, 45-47% op margin) underscores structural durability — KLA sits in the ASML/MSCI tier, second only to ASML in semicap structural durability.

## Growth

Q4 FY2026 (reported July 28, 2026) revenue $3.66B — a record, +15% YoY and +7% sequentially — with non-GAAP gross margin 62.4%, non-GAAP operating margin 43.7%, and non-GAAP EPS $1.05 against a $1.00 consensus. FY2026 closed at $13.58B revenue (+11.7% YoY), $3.66 GAAP EPS and $3.77B free cash flow. The September quarter is guided to $4.0B ±$200M (+25% YoY) with non-GAAP EPS $1.16 ±$0.10 — a step up, not a continuation. Backlog exits FY2026 at ~$12.5B, management raised its 2026 wafer-equipment market view to the low $150B range, and the industry view for 2027 is ~$190B. Advanced-packaging process control is guided to ~$1.1B in calendar 2026 from $635M in 2025. The offsetting facts: memory pricing is a >100bp gross-margin headwind management expects to persist through 2027, and the 2027 acceleration rests on a market forecast rather than on backlog.

- **Revenue CAGR estimate:** 14-17%
- **Primary type:** both
- **Margin trend:** stable
- **Key risk (moderate):** The ~$190B CY2027 wafer-equipment market that underwrites the acceleration is a forecast, not orders — the ~$12.5B backlog covers roughly three quarters at the guided $4.0B run-rate. If hyperscaler capex digestion holds 2027 WFE near the 2026 low-$150B level instead of growing ~26%, the September-quarter guide is the cycle peak and revenue flattens through FY2027 with the memory-pricing headwind still in the gross margin.
- **Drivers:**
  - Leading-Edge Foundry/Logic — Q4 FY26 +15% YoY; Q1 FY27 guided $4.0B, +25% YoY (accelerating)
  - Advanced Packaging — ~$1.1B CY2026 vs $635M CY2025, +70% — ~2× market growth (accelerating)
  - Memory / HBM — Demand broadening across DRAM, NAND and HBM4 stacking beyond the single leading-edge customer (accelerating)
- **Score derivation:** Base 80 (14-17% blended CAGR — the +24.6% Q1 FY2027 guide decayed toward the 13-17% 2030 framework, not the +11.7% FY2026 actual and not the guide itself) + 4 trajectory (3 of 3 drivers accelerating) + 0 margin (record 62.4% gross margin and 43.7% operating margin, but a >100bp memory-pricing headwind through 2027 offsets the operating leverage) − 5 risk (the ~$190B CY2027 wafer-equipment market is an expectation, not backlog) = 79

## Valuation

The June review caught KLA at the top. Shares peaked at ~$302 on June 30, fell through July with the rest of semicap, and dropped a further 6% into the Q4 print before recovering to ~$184 — a ~39% drawdown from the high, even though the quarter beat and the September guide raised the run-rate 25% YoY. The forward multiple has gone from ~53× to ~37×, which puts the price between the bear ($130) and base ($215) cases and restores a margin of safety the June file explicitly said was gone.

| Multiple | Value | Note |
| --- | --- | --- |
| Trailing P/E (GAAP) | ~50× | FY2026 GAAP EPS $3.66 |
| Forward P/E (NTM) | ~37× | consensus FY2027 non-GAAP EPS ~$4.98 |
| PEG Ratio | ~1.8× | fwd P/E ÷ ~20% multi-year EPS CAGR |
| Price / Sales (NTM) | ~14× | ~$16.9B FY2027 revenue, ~$240B cap |
| Price / FCF | ~64× | FY2026 free cash flow $3.77B |
| Dividend | $2.30/sh | 17th consecutive annual increase; $7B buyback authorised |

The de-rating did the work the earnings did not. Forward P/E fell from ~53× to ~37× while FY2027 estimates rose, so KLA is no longer the outlier it was in June — ASML trades near ~48×, and Lam and Applied sit in the low-to-high 30s on recent data. PEG of ~1.8× is a normal price for a business with this moat. What is still rich is the cash-flow multiple: ~64× FY2026 free cash flow assumes the AI capex cycle keeps running, and FCF conversion has to catch up with reported earnings for the base case to hold. _(as of July 2026)_

## Price scenarios

### Bear — $130

CY2027 wafer-equipment spend flattens near the 2026 low-$150B level instead of the ~$190B consensus, memory pricing stays a >100bp gross-margin headwind, and the multiple reverts toward KLA's pre-AI band — ~26× FY2027 EPS.

- CY2027 WFE lands flat against 2026 rather than growing ~26%; the $4.0B September guide proves the cycle peak
- The ~$12.5B backlog (roughly three quarters of cover) converts without replenishment and FY2028 revenue is flat to down
- Memory pricing pressure persists through FY2027, holding gross margin near 62% against the 60-65% incremental model

### Base — $215

CY2027 WFE reaches roughly $190B, KLA compounds at 14-17%, advanced packaging scales past the ~$1.1B calendar-2026 level, and the multiple holds ~43× FY2027 / ~35× FY2028 EPS.

- FY2027 revenue ~$16.9B (+24%) off the guided $4.0B September run-rate; non-GAAP EPS ~$4.98
- Advanced packaging keeps compounding above market as HBM4 and chiplet stacking raise process-control intensity per wafer
- Operating margin grinds from 43.7% toward the 45-47% 2030 target; FY2028 EPS ~$6.2

### Bull — $300

AI capex runs longer than the usual two-year semicap cycle, 2027 WFE overshoots $190B, memory pricing recovers, and the multiple re-rates back toward ~48× FY2028 EPS.

- CY2027 WFE exceeds $190B and 2028 grows again on hyperscaler ASIC programmes and sovereign fab buildouts
- Advanced packaging passes $2B as HBM4/HBM5 stacking and panel-level packaging expand the process-control TAM
- Memory pricing normalises and gross margin clears 64% on the 60-65% incremental model; FY2028 EPS ~$6.5-7.0
