Summary of Conference Call Notes Industry Overview - **Industry**: Electronic Components in Japan - **Key Companies**: Ibiden, TDK, Murata, Taiyo Yuden, HDD manufacturers Core Insights 1. **Investor Interest in HDDs**: There has been a notable increase in investor inquiries regarding HDDs, particularly concerning the production bottlenecks and capacity increases for NL-HDDs in data centers. The production volume of NL-HDDs dropped from 7.45 million units in June 2022 to 2.60 million units in June 2023, with a partial recovery to 6.16 million units by May 2025 [8][8][8] 2. **Earnings Growth Expectations**: Investors have high expectations for Ibiden's earnings growth in the medium term, driven by its significant market share in FC packages for NVIDIA GPUs. However, there are concerns regarding near-term earnings for F3/26 [3][3][3] 3. **AI and Computing Demand**: Companies like Ibiden, TDK, and Murata are expected to benefit from the growing demand for computing components due to the rise of AI technologies. Ibiden is projected to see substantial increases in unit prices of its FC package boards with each new GPU generation [2][2][2] 4. **TDK's Market Position**: TDK has a ~40% share of the global mobile device battery market and is anticipated to see significant sales and profit growth from rechargeable batteries starting in F3/26 2Q. However, there is skepticism among investors regarding TDK's communication strategy about its earnings [4][4][4] 5. **Murata's Earnings Potential**: Investors believe that while Murata's F3/26 1Q earnings are favorable, concerns about declining sales of RF modules for 2025 model smartphones may hinder share price growth. The demand for MLCCs is expected to have a more significant impact on earnings than RF modules [7][7][7] Additional Important Points 1. **Production Bottlenecks**: The decline in NL-HDD production is attributed to workforce reductions during previous downturns, making it challenging to scale up production in response to rising demand. Companies like Suncall have exited the suspension manufacturing market, contributing to supply issues [8][8][8] 2. **Market Dynamics**: The market is demanding increased capacity for NL-HDDs, with manufacturers raising product capacities to 24TB and beyond. This shift is creating a competitive landscape where bottlenecks in production are a critical concern [8][8][8] 3. **Valuation and Risks**: Ibiden's valuation is based on a DCF model with a WACC of 6.3%. Risks include potential competition from overseas in the ABF package market and weaker-than-expected demand for CPUs [15][16][16] Conclusion The electronic components industry in Japan is experiencing significant interest from investors, particularly in the context of AI and computing advancements. Companies like Ibiden, TDK, and Murata are positioned to benefit from these trends, although they face challenges related to production capacity and market dynamics.
