Japanese AI infrastructure investment ideas Report Interpretation

Overview

Ahead of its Japan Conference, BofA presents four AI-linked Japanese equity ideas. The report argues that AI infrastructure demand reaches beyond chips into optical transceivers, power supplies and semiconductor-process chemicals, supporting Buy views on Dexerials, Nichicon and Kao; Nippon Chemi-Con remains Neutral despite its AI-server exposure.

Core views

The report frames its Japan ideas around the broader hardware consequences of AI-server deployment. More AI-server clusters, more powerful GPUs and higher server power consumption are expected to increase demand for both high-speed optical connectivity and higher-output power-supply components. BofA therefore highlights companies exposed to photodiodes, aluminum electrolytic capacitors and semiconductor chemicals rather than treating AI demand as limited to core processors. Dexerials is initiated at Buy. BofA argues that the company is evolving from a traditional smartphone and PC component supplier into an AI-infrastructure beneficiary. Its photodiodes are used in optical transceivers for data centers, and the analyst expects photodiodes to become the principal earnings driver as AI-server deployments expand. Greater connectivity within AI-server clusters and faster optical transceivers should lift both photodiode volumes and average selling prices. The report also expects Dexerials' high-margin anisotropic conductive film and anti-reflection film businesses to outperform their end markets, and considers the company's revised medium-term plan conservative. The ¥4,700 price objective uses 20x FY3/28E P/E, matching the stock's average multiple since the May 2026 FY results, when investor perception began shifting toward an AI-server/CPO growth story. For aluminum electrolytic capacitors, BofA expects higher server power requirements to raise component value per high-output power supply unit. It initiates Nichicon at Buy and Nippon Chemi-Con at Neutral. Nichicon is preferred because BofA sees broader growth opportunities, stable energy-storage earnings and a more balanced risk-reward profile. Its ¥3,300 price objective is based on 9.6x FY3/28E EV/EBITDA, 15% above the past decade's historical peak average of 8.4x, reflecting expected AI-server market expansion and sustainable profit generation in film capacitors for xEV applications. Nippon Chemi-Con has higher exposure to AI-server demand, but BofA believes that advantage is offset by preferred-share-conversion dilution, Singapore Dyson litigation exposure and below-peer shareholder returns. Its ¥3,000 price objective uses 7.3x FY3/28E EV/EBITDA, about 10% below the past decade's peak-multiple average of 8.2x. The report notes potential upside from AI-server capacitor market-share gains, broader adoption of high-value products, industrial-market recovery and financial improvement, but these do not change its Neutral rating. Kao is upgraded from Neutral to Buy as BofA expects profitability to improve across Consumer Products, Cosmetics and Chemicals. The differentiating element is Kao's semiconductor-chemicals business: the company reports leading positions in specialty NAND process chemicals and about 60% share in package-substrate cleaning agents. Its Taiwan precision-cleaning center near TSMC is intended to deepen customer engagement. BofA sees Kao as one of few companies with exposure to both front-end and back-end semiconductor processes and believes the market underappreciates the franchise's long-term value, adding upside to the improving core businesses. The ¥4,000 price objective applies 3.2x P/B, based on the historical correlation between P/B and ROE, to FY12/27E book value per share using BofA's FY12/27E ROE forecast.

Analysis framework

BofA links AI-server deployment to specific hardware demand channels, then evaluates each company’s product exposure, earnings drivers and company-specific risks. It supports price objectives with forecast-year valuation multiples: P/E for Dexerials, EV/EBITDA for the capacitor makers, and P/B linked to forecast ROE for Kao.

Impact & implications

The report argues that AI infrastructure broadens the set of potential beneficiaries beyond semiconductor designers: optical transceiver components can gain from faster connectivity, capacitor suppliers from higher power needs, and chemical suppliers from semiconductor-process demand. BofA favors the names where this exposure is paired with supportive operating trends or a more balanced risk-reward profile.
