Citi raises target prices on U.S. semiconductor equipment stocks such as LRCX, bullish on CY2028 WFE reaching $250B

Overview

This is a Citi research report on the U.S. semiconductor equipment industry and on AMAT, LRCX, and KLAC. The core view is that investor focus is extending from 2027 into 2028, with AI data center capex, capacity expansion by TSMC and memory makers, progress at Intel and Samsung foundries, and DRAM supply bottlenecks jointly supporting continued upside in wafer fab equipment spending (WFE). The report focuses on LRCX and raises its target price to $450.

Core views

Citi remains positive on semiconductor equipment stocks. The report incorporates CY2028 WFE into its model, with bull-case CY2026/CY2027/CY2028 WFE of about $145B/$200B/$250B. For LRCX, Citi forecasts total revenue growth of 28%/22% YoY in CY2027/CY2028, including Systems growth of 36%/25% and CSBG growth of 12%/13%; the target price is raised from $315 to $450, valued at 40x P/E on CY2028 earnings. The report believes LRCX benefits from the 3D devices trend, AI data center capex, NAND equipment exposure, service revenue contribution, and higher equipment capital intensity.

Analysis framework

The report uses a top-down WFE demand forecast, company segment revenue modeling, CY2028 earnings roll-forward, and P/E multiple valuation. At the industry level, it first estimates WFE scale based on hyperscaler capex models, fab expansion, and memory demand; at the company level, it then aligns revenue and profit forecasts for AMAT, LRCX, and KLAC with the revised WFE model and derives rolling target prices based on CY2028 EPS.

Methodology notes

• Industry demand forecastingTop-down WFE model

  Derive wafer fab equipment spending from AI capital expenditure, fab expansion, and memory supply-demand dynamics.

  Based on its updated hyperscaler capex model, Citi assumes capex growth of 84%/56%/38% in CY2026/CY2027/CY2028 and accordingly raises its bull-case WFE scenario to about $145B/$200B/$250B.

• Valuation methodsCY2028 earnings power and P/E valuation

  Roll target prices to CY2028 EPS and value them using P/E multiples above historical averages but below peak levels.

  LRCX uses 40x P/E on CY2028 EPS, above the 3-year historical average of 24x but below the 48x peak; AMAT uses 31x and KLAC uses 40x.

• Technology theme analysisDRAM bottlenecks and incremental NAND demand

  Agentic AI inference expands KV cache size, making low-cost, high-capacity NAND part of the tiered memory architecture.

  The report argues that tight DRAM supply and rising costs will drive adoption of KV cache offloading, PCIe Gen6 SSDs, HBF, XL-FLASH, and similar solutions, thereby increasing NAND WFE demand.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• LAM RESEARCH CORP (LRCX)

  Core covered company, rated Buy, with target price raised to $450.

  Strengths

  Benefits from the 3D devices trend, AI data center capex, multi-year WFE upside, NAND equipment exposure, service revenue accounting for about one-third, and higher etch/deposition capital intensity.

  Weaknesses

  The valuation multiple is already above the historical average and is sensitive to realization of CY2028 WFE and earnings.

  Comparison

  Compared with AMAT and KLAC, LRCX has more pronounced exposure to NAND and etch/deposition, making it a more direct beneficiary of NAND WFE upside driven by DRAM bottlenecks.

  Risks

  Intensifying competition in deposition and etch, weaker-than-expected overall semiconductor demand especially memory demand, and China demand affected by U.S.-China trade and IP tensions.

• Applied Materials Inc (AMAT)

  A U.S. semiconductor equipment company in the same report with a raised target price of $710.

  Strengths

  A leader in materials engineering, benefiting from higher WFE, GAA, advanced packaging, ICAPS, and AI data center investment.

  Weaknesses

  As a leader across multiple equipment subsegments, it can benefit from cycle turning points but also faces competitive pressure from major peers.

  Comparison

  AMAT has broader exposure and is valued at 31x P/E, below the 40x P/E used for LRCX and KLAC.

  Risks

  Deviation in fab utilization, capital equipment orders, or supply-demand models could cause the valuation framework to miss the mark.

• KLA Corp (KLAC)

  A process control equipment company in the same report with a raised target price of $290.

  Strengths

  Benefits from rising process control intensity and a multi-year AI-driven WFE upcycle.

  Weaknesses

  The valuation multiple is above the historical average and depends on rerating driven by AI WFE exposure.

  Comparison

  KLAC is more focused on process control and SPC-related sales, and is valued at 40x P/E.

  Risks

  Competitive pressure from AMAT/ASML and others, foundry inventory adjustments, and slower-than-expected adoption of Gen 4/5 and EUV products.

• NAND equipment and enterprise SSD supply chain

  A key incremental demand theme in the report.

  Strengths

  Agentic AI inference expands demand for KV cache and tiered memory, pushing NAND from passive storage toward an active inference memory layer.

  Weaknesses

  Demand realization depends on the maturity of architectures and product roadmaps such as KV cache offloading, CXL, HBF, and XL-FLASH.

  Comparison

  Compared with high-cost HBM/DRAM, NAND provides a lower-cost, higher-capacity complementary layer.

  Risks

  If DRAM supply improves, AI inference architectures change, or high-performance NAND adoption is slower than expected, related equipment demand could fall short of the report’s assumptions.

Impact & implications

If Citi’s WFE and NAND demand outlook materializes, the investment narrative for semiconductor equipment stocks will shift from a short-cycle recovery to a multi-year AI-driven capex upcycle. LRCX stands out relatively for its NAND and etch/deposition exposure, 3D devices trend, and service business contribution; AMAT benefits from materials engineering, GAA, advanced packaging, and ICAPS; KLAC benefits from rising process control intensity. From a valuation perspective, the target price increases depend on the market accepting higher P/E multiples, so order trends, WFE timing, and progress in AI-related NAND adoption will be key validation points going forward.

Risks

• WFE may enter a digestion phase in 2028, leading to equipment orders and revenue growth below the bull-case scenario.
• Memory demand, especially NAND or DRAM recovery, may be weaker than expected, potentially pressuring revenue for LRCX and related equipment vendors.
• Competition in deposition, etch, and process control may intensify, potentially causing share loss or margin pressure.
• U.S.-China trade and IP tensions may cause China demand to be slower than expected.
• Valuation upside depends on AI-driven rerating and high P/E multiples; if market risk appetite declines, target price assumptions may come under pressure.
• The report discloses that Citigroup Global Markets Inc. or its affiliates have client service, non-investment-banking service, or material financial interest relationships with Applied Materials Inc, KLA Corp, and Lam Research Corp; readers should pay attention to conflict-of-interest disclosures.
