Financial Trends -- 9.2/10

• Revenue grew from $2.36B in CQ1 2024 to $3.30B in CQ4 2025, a 40% increase over 8 quarters with sequential growth nearly every period
• CQ4 2025 YoY revenue growth of +7.1% masks underlying strength -- $300-350M of lost China revenue from Dec 2024 export controls; organic growth was likely mid-teens
• Non-GAAP gross margins expanded ~470bps from 57.9% in CQ1 2024 to 62.6% in CQ4 2025, reflecting favorable mix and operating leverage
• Operating margins expanded from 36.8% to 42.8%, consistently above 42% in the last 5 quarters -- industry-leading for semi equipment
• Non-GAAP EPS grew from $5.26 to $8.85, a 68% increase over 8 quarters driven by revenue growth, margin expansion, and steady buybacks

• Semi Process Control (core business, ~91% of product revenue): Grew from $2,096M to $3,005M (+43% over 8Q), driven by AI fab buildouts and process control intensity gains
• Services ($786M in CQ4 2025, +18% YoY): The compounding flywheel -- 16 consecutive years of annual growth at 12%+ CAGR. Higher tool utilization from AI inference fabs and growing installed base drive expansion
• Specialty Semi ($141M) and PCB/Component Inspection ($152M): Smaller segments with more cyclical behavior. PCB showed strength in CQ3 2025 ($189M) before normalizing
• Services now represents ~24% of total revenue, providing a growing recurring revenue floor that dampens cyclicality

• Memory share surged from 18% in CQ2 2024 to 40% in CQ4 2025 -- a structural shift driven by HBM and EUV adoption in DRAM
• Historically, DRAM process control intensity was 9-10% of WFE; EUV insertion added ~100bps, HBM added another ~100bps -- a permanent elevation
• Management guided CQ1 2026 memory at 40% with DRAM comprising 85% of memory. Per management: "DRAM is looking much more similar to what logic did not that long ago"
• Foundry/Logic remains the majority at 60% but has compressed from 82% as memory intensity catches up -- this diversification reduces concentration risk
• The HBM-driven intensity shift is structural, not cyclical: less redundancy, bigger die with TSVs, more metallization layers, tighter reliability specs

• CQ4 2025 FCF of $1.26B was a quarterly record, up 66.7% YoY from $0.76B in CQ4 2024
• TTM FCF reached $4.4B (record), representing a 34% FCF margin on trailing revenue
• Operating cash flow inflected sharply in CY2025, rising from $3.65B (CY2024) to $4.76B -- a 30%+ increase
• CapEx remains modest at ~$100M/quarter (~3% of revenue), reflecting KLA's asset-light model vs. peers
• FCF CAGR of 20% over 5 years exceeds the 16% revenue CAGR, demonstrating superior cash conversion

• Revenue grew from $5.81B (CY2020) to $9.81B (CY2024), a 14% CAGR over 4 years. CY2025 was a record $12.7B (+30% YoY)
• CY2024 was a down year (-6.5% YoY) driven by China export restrictions and WFE normalization, but CY2025 demonstrated strong recovery
• Non-GAAP operating margins expanded from 35.0% to 41.0%, with CY2025 reaching ~43.6% -- industry-leading for semi equipment
• Non-GAAP EPS compounded from $10.35 to $23.74 (23% CAGR over 4 years), with CY2025 EPS growing 29% to ~$35.45
• FCF nearly doubled from $1.63B to $3.03B over 4 years (17% CAGR), with CY2025 reaching a record $4.4B
• Services grew every single year from $1.48B to $2.33B (12% CAGR) -- 16 consecutive years of annual growth

• KLA beat revenue guidance midpoints in all 5 quarters, with an average beat of ~2.8%
• KLA beat EPS guidance midpoints in all 5 quarters, with an average beat of ~5.1%
• Gross margin has consistently come in at or above guided midpoint
• The pattern of conservative guidance and consistent overdelivery is a hallmark of KLA's operating discipline under Rick Wallace
• Largest beats came in CQ4 2024 (Rev +4.4%, EPS +5.8%) and CQ2 2025 (EPS +10.0%)

• FY2026E (ending Jun 2026) revenue of ~$13.0B reflects only the first half of the CY2026 ramp; FY2027E of ~$15.5B captures the full acceleration
• At ~$1,517, KLAC trades at ~43x FY2026E EPS and ~35x FY2027E EPS -- premium but justified by monopoly position and structural tailwinds
• On a CY2026 basis (management guides mid-single-digit growth, implying ~$14B revenue and ~$38 EPS), the PE is ~40x
• Street models may underappreciate: (1) structural DRAM intensity shift from HBM, (2) advanced packaging as a new $950M+ TAM, (3) e-beam inspection inflection, (4) custom silicon proliferation from hyperscalers
• FCF yield of ~2.2% ($4.4B TTM on $199B market cap) is modest, but FCF growth trajectory is steep

KLA delivered CY2025 record revenue of $12.7B (+30% YoY), Non-GAAP EPS growth of 29%, and record free cash flow of $4.4B (34% margin). This was achieved despite absorbing $300-350M in lost China revenue from December 2024 export controls, masking even stronger underlying organic growth. The company's financial profile is exceptional across every metric: 62.6% gross margins, 43%+ operating margins, and 20% FCF CAGR over 5 years.

The revenue model has structural durability. Semi Process Control systems revenue ($3.0B in CQ4 2025, +9% YoY) benefits from rising process control intensity at every new node, while the Services flywheel ($786M, +18% YoY) has grown for 16 consecutive years at 12%+ CAGR. Together, these provide both growth and visibility. The memory end market shift -- from 18% to 40% of semi PC revenue in just 2 years -- is not cyclical but structural, driven by HBM architecture and EUV adoption in DRAM.

Capital allocation is disciplined: $3.0B in LTM capital returns (buybacks + dividends), 16 consecutive annual dividend increases, steady share count reduction (~2.5% over 6 quarters), and investment-grade balance sheet. CapEx at ~3% of revenue reflects the asset-light model.

Guidance accuracy is outstanding: revenue and EPS beats in every quarter, with average beats of ~2.8% and ~5.1% respectively. Management consistently underpromises and overdelivers.

The only deduction: CY2024 was a down year (-6.5% revenue) reflecting WFE cyclicality and China restrictions. Gross margins guided modestly lower for CY2026 (62% +/- 50bps) due to transitory DRAM component cost inflation. These are minor blemishes on an otherwise pristine financial profile.

Score: 9.2/10 -- Record revenue, EPS, and FCF in CY2025. Industry-leading margins. 20% 5-year FCF CAGR. Flawless guidance track record. Services compounding for 16 years. Deducted for CY2024 cyclical downturn and near-term gross margin headwinds from DRAM costs.
