Furthermore, the report offers detailed financial projections and risk assessments for the key companies under coverage, along with specific rating recommendations.

Core views

Demand Side: A Dual-Engine Driver The research report argues that the electronic components industry is currently propelled by two major trends: first, the widespread adoption of AI computing infrastructure; and second, robust demand in the North American market for high-value-added smartphone components. With hyperscalers—large cloud service providers—significantly ramping up capital expenditures, demand remains strong for AI‑server‑related components such as ABF packaging substrates, connectors, and MLCCs. Meanwhile, despite overall pressure on profit margins stemming from the commoditization of smartphones, high‑value‑added parts—including high‑performance camera actuators and premium MLCCs—continue to offer opportunities for earnings growth. Key Company Recommendation Rationale TDK (6762.T, Overweight, Top Pick): As the preferred stock, TDK stands to benefit from expanding profitability in its rechargeable battery business and steady performance in HDD‑related products. The report forecasts sustained medium‑to‑long-term earnings growth, driven not only by lithium batteries but also by HDDs, sensors, and passive components. Murata Manufacturing (6981.T, Overweight): We are optimistic about the growing demand for its high‑value‑added MLCCs (multilayer ceramic capacitors) and the maintenance of elevated utilization rates. Rising MLCC requirements from AI servers should help sustain strong margins, while RF module sales are expected to bolster profitability after FY2023 Q3. Alps Alpine (6770.T, Overweight): Starting in April–June, shipments of high‑performance smartphone camera actuators are anticipated to ramp up, contributing significantly to earnings. Although below the company’s mid‑term targets, results are still projected to substantially exceed market consensus. Niterra (5334.T, Overweight): The company continues to deliver solid earnings growth in both the automotive spark plug replacement market and its semiconductor manufacturing equipment (SPE) electrostatic chuck business. While total spark plug demand remains relatively flat, Niterra has been steadily expanding its market share and enjoys attractive aftermarket margins. Hirose Electric (6806.T, Overweight): The firm benefits from expanding profitability in general industrial machinery and AI server connector markets. Its fabless production model sustains high margins, while securing high‑margin projects has fueled continued revenue growth. Cautionary Recommendations Ibiden (4062.T, Underweight): Despite an expected near‑100% market share in NVIDIA’s FC packaging segment and rising ABF packaging sales for AI servers, the report believes market expectations may be overly optimistic. With glass cloth shortages likely to persist through FY2023 Q3 and new production lines driving higher costs, FY2023 Q3 earnings could fall short of overly bullish projections, posing downside risks to the stock price. Hamamatsu Photonics (6965.T, Underweight): A decline in FY2022 Q3 earnings appears unavoidable, and even if recovery begins in FY2023 Q1, a full rebound will take considerable time. High inventory levels suggest that it will require time for utilization rates to improve and for profits to fully recover. Industry Trends and Competitive Landscape The report highlights that smartphone commoditization may exert downward pressure on profit margins, yet automotive electrification and other emerging applications are opening new avenues for growth. In a weak yen environment, Japanese electronic component manufacturers enjoy enhanced cost competitiveness relative to their South Korean, Taiwanese, and Chinese counterparts—particularly those with a higher proportion of domestic production or lower reliance on imported materials, such as Murata, Taiyo Yuden, and Nippon Chemi-Con. However, for companies with significant overseas production, exchange rate fluctuations have a more limited impact on competitiveness.

Analysis framework

The research report employs a hybrid analytical approach that combines top-down and bottom-up methodologies. First, starting with macroeconomic and industry trends, the report identifies two key drivers: the widespread adoption of AI computing and surging demand for high‑value‑added smartphone components in North America. By examining hyperscaler capital expenditure patterns and the structural shift in the smartphone market—from volume‑driven growth to value‑driven growth—the report establishes a robust foundation for assessing industry cyclicality. Second, the analysis delves into specific sub‑segments to conduct supply‑and‑demand assessments. For instance, in the MLCC space, attention is paid to utilization rates and the share of high‑margin products; in the packaging substrate segment, focus is placed on the market share of GPU‑based AI server packages and the associated technological barriers; and in automotive electronics, the analysis highlights the increased per‑vehicle component usage driven by electrification and智能化. Finally, the report conducts stock‑specific screening by integrating company fundamentals. By comparing earnings forecasts, valuation metrics (P/E, P/B, EV/EBITDA), currency sensitivity, and competitive advantages—such as technological moats, market share, and production footprint—the report assigns tailored ratings and price targets. Notably, the report underscores the importance of “expectation gaps”: it adopts a cautious stance toward companies whose market consensus is overly optimistic (e.g., Ibiden), while assigning a more bullish rating to firms poised to deliver earnings that exceed expectations (e.g., TDK, Murata).
