Report interpretation
Overview
This is a company research and rating update report on TDK by BofA Securities. In response to FY3/26 results, the report raises earnings forecasts, lifts TDK's target price from ¥2,800 to ¥3,500, and reiterates Buy. The core view is that concerns about a sharp deterioration in battery profitability are easing, magnetic application products are rebounding strongly on data center nearline HDD demand, passive components still have room to grow in automotive and AI server applications, and shareholder returns may improve after the structural reforms.
Core views
The report's core view has four pillars: first, TDK's core battery business is more stable in the near term and still has significant medium- to long-term growth potential, especially through share gains in small batteries, ASP improvement, and the opportunity for medium-size batteries in AI data centers; second, profitability in Magnetic Application Products is clearly improving, with heads and suspensions benefiting from nearline HDD expansion and segment profit expected to grow sharply in FY3/27; third, passive components are supported by automotive electrification and AI server applications, although slowing automotive orders need monitoring, long-term demand support remains intact; fourth, after completing the midterm plan's restructuring of low-ROIC businesses, the next phase of shareholder return policy could become a catalyst for the share price.
Analysis framework
The report uses a framework of earnings forecast revisions, segment trend analysis, and relative valuation. BofA uses FY3/28E EPS as the valuation base, and the target price corresponds to 25x P/E, above the upper end of the company's past five-year range, on the grounds that battery visibility has improved and TDK's valuation re-rating potential as an AI-related company has increased. Segment analysis focuses on Energy Application, Batteries, Magnetic Application, Passive Components, Sensors, and shareholder returns.
Methodology notes
price-to-earnings target price method
The ¥3,500 target price is based on BofA's 25x P/E applied to FY3/28 earnings per share. The prior basis was 20x, and the report argues that battery business stability and AI-related valuation uplift justify a higher multiple.
segment profit forecasting
The report breaks down sales, operating profit, and growth drivers by segment, including Energy Application, Magnetic Application, and Passive Components, to assess the quality and sustainability of the earnings recovery.
standardized financial quality and valuation metrics framework
The report discloses that BofA uses a standardized methodology incorporating business performance, earnings quality, and valuation validation to support comparability across global research.

Impact & implications
For investors, BofA is positioning TDK more clearly as an AI beneficiary rather than a traditional electronic components company: nearline HDD demand from data centers supports heads and suspensions, AI servers drive demand for MLCCs, inductors, and aluminum electrolytic capacitors, and AI data center UPS, BESS, and BBU create room for medium-size battery expansion. If battery profitability stability continues to be validated, Magnetic Application earnings keep recovering, and shareholder return policy is explicitly strengthened, TDK may sustain a valuation above its historical range.
Risks
- Battery business growth could slow more sharply, especially if shipments of smartphones, PCs, and tablets weaken.
- Rising cobalt prices and changes in China's VAT rebate policy could squeeze battery profitability, although the report believes TDK has some pricing power.
- HDD market inventory buildup or slower component demand could affect head and suspension shipments.
- Passive component demand from automotive may be hurt by a slowing Chinese BEV market and pre-buying effects.
- Sensor business profit expansion, especially in automotive applications, may lag expectations.
- Adoption of medium-size batteries for AI data center BBUs, UPS, and BESS may be slower than the company's target or BofA's forecast.
- The research disclosure shows that BofAS and TDK Corp. have investment banking or non-investment banking client relationships, so investors should note potential conflicts of interest.
What to watch
- Whether FY3/27 and FY3/28 battery segment operating profit resumes growth as expected after a temporary pause.
- Recovery in battery shipments to major North American customers, and whether small battery ASP and margins can be supported by a higher-value product mix.
- AI data center medium-size battery orders, BBU adoption progress, and the achievability of the FY3/31 sales target.
- Whether quarterly head shipments rise from slightly above 50mn to around 70mn, and whether expansion in supply to U.S. customers continues.
- Nearline HDD demand, HAMR drive ramp-up, and head ASP trends.
- Whether passive component orders and book-to-bill stay above 1.0, especially for automotive and AI server-related demand.
- Progress on the remaining five business units in the structural reforms, and whether the next midterm plan clearly strengthens dividends or buybacks.
