Hidden within the unassuming quarterly transcript of <a href="https://www.tel.com/en/" alt="Tokyo Electron Website">Tokyo Electron (OTCPK:TOELY)</a>, a Japanese semiconductor equipment manufacturer, lies a clue that may have escaped the attention of most analysts: a potential surge in NAND flash investment starting in the latter half of fiscal year 2025. This subtle hint, revealed during a seemingly routine exchange about projected sales figures, suggests that Tokyo Electron is privy to insider knowledge regarding a significant shift in the NAND flash landscape.

While Tokyo Electron's CEO, Toshiki Kawai, acknowledged the current subdued state of NAND investment due to ongoing inventory adjustments, he pointed towards a significant sales increase for NAND customers in the second half of fiscal year 2025. When pressed about the basis for this optimistic projection, Kawai indicated that it stemmed from the "investment plans shared by the customers for NAND."

This statement holds more weight than it appears at first glance. Tokyo Electron, known for its close relationships with major memory manufacturers, likely receives detailed long-term production plans from its key clients. This insight gives Tokyo Electron a unique vantage point into future investment trends, making their projections more akin to informed forecasts than mere speculation.

The timing of this projected NAND flash surge aligns with the anticipated emergence of groundbreaking 3D NAND technology. Currently, manufacturers are pushing the boundaries of vertical stacking, with initiatives underway to achieve 300 layers and beyond. This dramatic increase in density promises a substantial boost in storage capacity, ushering in a new era of high-performance, ultra-high-capacity memory solutions.

Tokyo Electron's portfolio aligns perfectly with the demands of this impending 3D NAND revolution. The company highlighted several key technologies in its transcript, including high-throughput etching, peripheral circuit processing, and multi-layer stacking – all essential for the successful implementation of advanced 3D NAND structures.

Let's delve into the numbers. Tokyo Electron projects NAND sales of JPY 38.5 billion in the first half of fiscal 2025, followed by a staggering jump to JPY 91 billion in the second half. This represents a 136% increase, signaling a substantial ramp-up in NAND investment.

Hypothesis:

Tokyo Electron's projected NAND flash sales surge suggests that major memory manufacturers are planning to initiate substantial investments in 3D NAND technology starting in late 2024 and accelerating through 2025. This investment wave, fueled by the promise of significantly higher storage capacities, could mark the beginning of a 3D memory revolution, with far-reaching implications for the semiconductor industry.
