Summary of Conference Call Notes Industry Overview - The conference call focuses on the hard disk drive (HDD) industry, particularly the companies Seagate and Western Digital (WD) [1][2]. Key Insights and Arguments - **Nearline Storage Demand**: There is a significant increase in nearline storage demand, with a projected growth rate of 25% over the next three years. HDD supply shortages are expected to persist until 2026, granting pricing power to Seagate and WD, which will drive the adoption of high-capacity HDDs and the application of Hammer technology [1][3]. - **Cloud Computing Capital Expenditure**: There is a strong correlation (R-squared of 0.9) between cloud computing capital expenditure and HDD revenue growth. Continuous upward adjustments in cloud capital spending indicate robust growth potential for HDD revenues, benefiting related companies [1][4]. - **Impact of Artificial Intelligence (AI)**: The shift in AI towards multimodal reasoning is leading to an exponential increase in data storage needs, as the volume of generated data (images, videos) far exceeds that of text files. This trend is expected to significantly drive HDD demand [1][5]. - **Supply Shortages and Pricing Power**: The ongoing HDD supply shortage is providing Seagate and WD with pricing power, encouraging customers to adopt higher-capacity HDDs. This situation is also promoting the use of profit-generating technologies like Hammer, with Seagate's gross margin expected to reach 40% by the end of fiscal year 2026 [1][6]. - **Valuation of WD and Seagate**: The valuation methods for WD and Seagate involve comparing them with semiconductor hardware and networking companies related to data centers. Despite leading in revenue growth and cloud service revenue share, their price-to-earnings ratios are relatively low. Regression analysis suggests that their current enterprise value/sales ratio of 4-4.5 should rise to around 8, indicating significant upside potential. Target prices are set at $171 for WD and $265 for Seagate [1][7][8]. Other Important Insights - **Beneficiaries of the HDD Cycle**: The long-term strong HDD cycle not only benefits WD and Seagate but also positively impacts TDK (a key supplier of HDD heads and arms), Hoya (the sole supplier of glass substrates for HDD heads), and storage companies like SanDisk and Micron, which are also rated as buy due to the current strong NAND flash cycle driven by HDD shortages [2][9].
