pushing for more binding Long Term Agreements (LTAs), which we estimate could

fix c. 20-30% of total industry volumes and pricing for the next 2-3 years. This Kenji Yasui

would imply higher-for-longer ASPs and ROEs (which memory stocks are yet to Analyst

price in), but also upside to overall hyperscaler capex and memory capacity growth. kenji.yasui@ubs.com
