What the company does公司做什么
KLA makes the machines that find faults in computer chips while the chips are made. It does not make chips. It inspects them. A modern chip needs several hundred process steps, and one fault can spoil a whole wafer. KLA equipment finds the fault early, which is why every advanced factory buys it.KLA制造在芯片生产过程中查找缺陷的机器。它自己不造芯片，只负责检查。一块先进芯片要经过几百道工序，其中一个缺陷就可能毁掉整片晶圆。KLA的设备能及早发现缺陷，这就是每一家先进工厂都要买它的原因。
Earns from营收来源 it sells inspection machines to chip factories, then earns service fees on those machines for many years. Service was about 22% of revenue in FY2025.它把检测机器卖给芯片工厂，之后很多年里还能从这些机器上收取服务费。2025财年服务收入约占总收入的22%。

KLA Corporation, together with its subsidiaries, provides process control and process-enabling solutions for manufacturing wafers, reticles/masks, chemicals/materials, integrated circuits (ICs), packaged ICs, and printed circuit boards. It operates through three segments: Semiconductor Process Control; Specialty Semiconductor Process; and PCB and Component Inspection. The company offers inspection and review tools to identify, locate, characterize, review, and analyze defects on various surfaces of patterned and unpatterned wafers; chemical process control equipment; wired and wireless sensor wafers and reticles; wafer defect inspection, review, and metrology systems; reticle inspection and metrology systems; wafer inspection and metrology systems; semiconductor software solutions; KLA Pro systems; and specialty semiconductor manufacturing, benchtop metrology, surface characterization, material strength characterization, and electrical property measurement products. It also provides etch, plasma dicing, deposition and other wafer processing technologies and solutions; direct imaging, inspection, optical shaping, inkjet, and additive printing, as well as computer-aided manufacturing and engineering solutions; and components. In addition, the company offers service programs. It serves semiconductor, and semiconductor-related and electronic device manufacturers. The company operates in China, Taiwan, Korea, North America, Japan, Europe, Israel, and rest of Asia. The company was formerly known as KLA-Tencor Corporation and changed its name to KLA Corporation in July 2019. KLA Corporation was incorporated in 1975 and is headquartered in Milpitas, California.
Revenue breakdown营收构成 share of revenue营收占比
This segment makes the machines that check for faults on silicon wafers and photomasks during chip manufacture, and it measures features only a few nanometres wide. A single flaw can ruin an entire wafer, so chip factories buy this equipment to catch faults early and protect yield. KLA holds a leading share of this market, and each new advanced fab needs the equipment to reach an acceptable yield rate.该部门制造在芯片制造过程中检测硅晶圆和光掩模瑕疵、并测量仅几纳米宽的特征的设备。一个瑕疵就可能毁掉整片晶圆，因此芯片工厂购买这些设备以尽早发现瑕疵、保护良率。KLA在这个市场占据领先份额，每座新建的先进晶圆厂都需要这些设备才能达到可接受的良率。
- Wafer inspection晶圆检测 — Finds particles and pattern faults on a silicon wafer. KLA holds more than 85% of the optical wafer inspection market.找出硅晶圆上的颗粒和图案缺陷。KLA占据了光学晶圆检测市场85%以上的份额。
- Reticle inspection掩膜版检测 — Checks the photomask, which is the master pattern. A fault on the mask repeats on every chip printed from it.检查光掩膜，也就是母版图案。掩膜上的一个缺陷会重复出现在用它印出的每一颗芯片上。
- Metrology量测 — Measures the width and depth of features that are a few nanometres across, to confirm each step worked.测量只有几纳米宽的结构的宽度和深度，来确认每一道工序都做对了。
This segment builds deposition and etch tools used to make semiconductor devices for niche markets, such as power chips and sensors, rather than the leading-edge logic and memory chips its main segment serves. These markets are smaller, so the segment gives KLA a foothold in specialty chip production without the scale of its core inspection business. It broadens the company's reach across the wider chip industry, beyond pure process control.该部门制造用于生产功率芯片和传感器等细分市场半导体器件的沉积和刻蚀设备，而非其主力部门所服务的尖端逻辑和存储芯片。这些市场规模较小，该部门让KLA在专用芯片生产中占有一席之地，但规模不及其核心检测业务。它把公司的业务范围扩展到纯工艺控制之外的更广泛芯片产业。
This segment makes inspection equipment for printed circuit boards and finished electronic component packages, checking boards and packages for faults after they leave the wafer stage. It serves electronics makers rather than chip fabs, so it extends KLA's inspection expertise into the assembly stage of electronics production. It is the smallest of KLA's three segments.该部门制造用于印刷电路板和成品电子元件封装的检测设备，在晶圆阶段之后检查电路板和封装是否存在瑕疵。它服务的是电子产品制造商，而非芯片代工厂，因此把KLA的检测专长延伸到电子产品的组装阶段。这是KLA三个部门中规模最小的一个。

🔄 A2026-09-22 — first real file. HOLD [7.5]. FV $165-205 (base ~$185) entry $155-178 (strong add <$160) trim 42x fwd (~$228).
What's working
- The print cleared well: FQ4 rev $3.66B +15%, EPS beat, GM expanded to 62.4%, Sept guide $4.00B +24.6% at 62.5% GM; FY27 consensus revised up 7.7% to $5.43. The −10.8% next-day drop was tone, not numbers.
- Moat widening: 58% process-control share, ~6x the nearest rival, ROIC 39.4% → 41.6% on 16% more invested capital — the inverse of AMAT
- RE-ENTERED 8/27 — the
<$190rule fired at $183.54, round-tripping from $195.06. Now IN $165-190 at 25.9x fwd, below the 29.6x sector median. Best business in the group: 61% GM, 41% op margin, 31% FCF margin**, ROE 95%, majority share of process control (the toll booth every fab pays). Shares −4.1%/yr
Red flags
- But 34.1x FY27E, not Yahoo’s 27.6x — that figure uses FY2028 EPS → [[pitfall-vendor-forward-eps-is-the-wrong-fiscal-year]]
- Memory is 38% of process-control systems revenue, not the 15-25% assumed.
- FCF/net income decaying 110% → 92% → 78% (FY26 FCF +0.5% vs NI +18.9%, working-capital build). FCF yield 1.54%. ⭐ BUCKET RESOLVED — hold AVGO at size, not KLAC, purely on price: AVGO is 15-27% below its FV, KLAC sits on its midpoint. They are less correlated than the shared label implies (KLAC breaks on capex digestion / China; AVGO on hyperscaler in-sourcing or the $29B Anthropic SPV) — so owning both is fine; the SIZE was the problem. Target allocation 4.5% AVGO / 3.5% KLAC, combined bucket cap 8.5%. Closed to new money above $178. A recent build here should not be reversed — there is no thesis break, and selling at $185 what was bought at $184 pays frictions to fix a weighting with a position decision
Watch
- The prior entry was written the afternoon BEFORE the 7/28 print, with no frontmatter and no recheck — invisible to
kb.py staleand/thesis-driftfor 56 days. - The risk is the ESTIMATE, not the multiple — memory 15-25% of revenue, Korea 15-20% of geography. FV $155-185. Accumulate $165-190, strong <$160. Trim $260+. Fund from INTC/AMD as a quality upgrade within the semi sleeve — not a new AI bet.
🔄 A2026-09-22 —— 第一份真正的文件。 持有 [7.5]。 合理价值 $165-205（基准约 $185）· 买入区间 $155-178（<$160 强烈加仓）· 减持 42x 前瞻（约 $228）。 ** ⚠️ *上一条条目是在 7/28 财报前一天下午写的，没有 frontmatter，也没有 recheck 日期 —— 对 kb.py stale 和 /thesis-drift 来说隐形了 56 天。 * ✅ 财报顺利过关：FQ4 营收 $3.66B，+15%，每股收益超预期，毛利率扩张到 62.4%，9 月季度指引 $4.00B（+24.6%）且毛利率 62.5%；FY27 市场一致预期上调 7.7% 到 $5.43。 次日 −10.8% 的下跌是语气问题，不是数字问题。 ** ✅ 护城河在变宽：过程控制份额 58%，约为最接近的对手的 6 倍，ROIC 39.4% → 41.6%，而投入资本还多了 16% —— 与 AMAT 恰好相反。 🚩 但实际是 FY27E 的 34.1x，而不是 Yahoo 的 27.6x —— 那个数字用的是 FY2028 的每股收益 → [[pitfall-vendor-forward-eps-is-the-wrong-fiscal-year]]。 🚩 存储占过程控制设备收入的 38%，而不是假设的 15-25%。 ** 🚩 自由现金流/净利润在衰减：110% → 92% → 78%（FY26 自由现金流 +0.5%，而净利润 +18.9%，原因是运营资本堆积）。 自由现金流收益率 1.54%。 ⭐ 板块问题已解决 —— 重仓持有 AVGO，而不是 KLAC，纯粹是因为价格：AVGO 比它的合理价值低 15-27%，而 KLAC 就坐在自己的中值上。 它们的相关性比共用的标签所暗示的要低（KLAC 破位的原因是资本开支消化或中国；AVGO 是超大规模云厂商自研自产，或者那笔 $29B 的 Anthropic SPV）—— 所以两个都持有是可以的；问题出在仓位大小。 ** 目标是 AVGO 4.5% / KLAC 3.5%，合计上限 8.5%。 ** $178 以上不再投入新资金。

Why customers stay客户为什么留下
KLA holds about 56% of all process-control equipment worldwide. A new factory must buy it to reach an acceptable yield. The machines also hold years of the customer's own yield data, so a change of supplier means a loss of that record.KLA在全球所有工艺控制设备市场中占有约56%的份额。一家新工厂必须买它的设备，才能达到可接受的良率。这些机器还保存着客户自己多年积累的良率数据，所以换供应商就意味着丢掉这份记录。
