KIOXIA investor day sends positive signals, with BiCS/CBA technology and long-term agreements supporting structural margin improvement

Overview

This report reviews the information released by KIOXIA Holdings at its June 2 investor day. JPMorgan believes the company has above-market growth potential driven by AI inference and data center storage demand, mainly supported by eSSD product mix upgrades, leadership in BiCS/CBA technology, long-term agreements improving revenue and investment visibility, and potential shareholder returns.

Core views

The core views are: first, KIOXIA raised its medium- to long-term bit growth target from 20% to 22%, showing increased confidence in NAND demand; second, demand for multi-year LTAs from hyperscalers and enterprise customers is strong, helping reduce earnings cyclicality; third, the company is increasing its eSSD share through the CM, GP, and LC series, with a target of rising from about 10% to 15%; fourth, BiCS 8 and BiCS 10 represent the current and next-generation technology focus, which should support cost, performance, and energy-efficiency advantages; fifth, if FCF remains after capital expenditures, R&D, working capital, and other committed spending, management may start dividends earlier.

Analysis framework

The report primarily analyzes management commentary from the investor day, capital expenditure plans, eSSD TAM and inference workload growth estimates, product technology roadmap, long-term agreement coverage targets, and a relative valuation framework, while also assessing market expectations based on the stock's performance relative to peers.

Methodology notes

• Valuation methodsP/E relative valuation

  The target price uses average FY2026-27 EPS and about 7x P/E

  JPMorgan uses estimated average FY2026-27 EPS and applies a roughly 7x P/E multiple, derived by discounting the storage manufacturers' 15-year historical average P/E of about 8x by 10%, to reflect risks from potential stake sales by the Bain Capital-led Pangea consortium and insufficient updates on shareholder returns.

• Industry demandTAM/CAGR estimation

  eSSD TAM and AI inference workload growth

  Company guidance shows eSSD TAM rising from 295 EB in 2025 to 909 EB in 2028E, implying a 46% CAGR; inference workload CAGR is 86%, a key driver of demand expansion.

• Fundamental driversProduct mix and operating leverage

  Higher eSSD mix, lower bit cost, and greater capital efficiency

  The report believes that growth in eSSD demand, lower bit costs from advanced technology, scaled capital expenditure efficiency related to the SanDisk JV, and high operating leverage will drive revenue and earnings to grow faster than the broader NAND market.

• KIOXIA Holdings (285A.T)

  Core covered name, rated Overweight by JPMorgan

  Strengths

  AI inference is driving eSSD demand growth, the BiCS/CBA technology roadmap supports advantages in performance, reliability, and energy efficiency, and low bit costs plus SanDisk JV scale effects should help margins.

  Weaknesses

  The shareholder return roadmap still lacks clear quantitative indicators, LTA details have not been disclosed due to confidentiality, and short-term consumer NAND demand is weak.

  Comparison

  The stock rose 113% over the past month, outperforming storage peers at 75% and TOPIX at 5%; the company's eSSD TAM guidance of 46% CAGR is below JPMe's 61% CAGR.

  Risks

  A slowdown in AI demand, excessive capital spending leading to supply-demand deterioration, sharp NAND price increases suppressing demand, delays in new product development, semiconductor downcycles, and macro weakness.

• NAND/eSSD supply chain

  The main industry exposure behind KIOXIA's growth

  Strengths

  AI inference, data center capacity expansion, and demand for high-performance storage are driving eSSD TAM growth, while the three-layer product portfolio covers different performance and capacity scenarios.

  Weaknesses

  The industry remains cyclical, and demand for consumer end markets such as smartphones and PCs may be periodically weak.

  Comparison

  The company aims for data center business to account for at least 60% by FY2028, while JPMe's model assumes about 70%, indicating management guidance is relatively more conservative.

  Risks

  If industry capital spending rises too quickly or NAND price volatility becomes too large, demand, pricing, and earnings elasticity may weaken.

Impact & implications

For investors, the implication of the report is that KIOXIA's medium- to long-term investment thesis is more tied to AI storage demand, eSSD share expansion, and technological cost advantages than to simple short-cycle NAND price elasticity. If LTAs expand in coverage, they could improve demand and capital expenditure visibility and reduce earnings volatility; however, insufficient detail on the shareholder return path and agreement terms may limit the extent of near-term valuation re-rating.

Risks

• AI-related demand comes in below expectations or cannot remain above expectations.
• Aggressive capital expenditures worsen the NAND supply-demand balance.
• Rapid NAND price increases cause demand to weaken.
• New product development or mass production is delayed, especially for BiCS 10 and high-end eSSD products.
• Semiconductor downcycles lead to earnings deterioration.
• Macroeconomic weakness causes further slowing in consumer NAND demand.
• Potential share sales by the Bain Capital-led Pangea consortium may pressure valuation.
• The shareholder return policy lacks clear quantitative metrics, which may affect market confidence.

What to watch

• Whether actual LTA-signed customers, coverage, duration, and pricing mechanisms become clearer.
• Whether eSSD market share can rise from about 10% to 15%.
• Whether BiCS 8 reaches more than 80% of GB output by the end of 2026, and whether BiCS 10 samples in summer 2026 and enters mass production in 2027 as planned.
• Whether annual capital expenditures of about ¥470 billion in FY2026-FY2028 remain disciplined and match real demand.
• Whether the company starts dividends early in 2H FY2026 or establishes a progressive dividend policy in FY2027.
• Whether AI inference workloads and data center storage demand support eSSD TAM growth.
• Changes in consumer NAND demand, NAND prices, and the industry inventory cycle.
