Irvin Liu ALL YOU NEED TO KNOW: We’re updating our storage market model

415-800-0183 following IDC’s latest enterprise storage forecast. Given a stronger-

irvin.liu@evercoreisi.com than-expected Mar-qtr result and a more severe memory/component

Victor Santiago pricing environment, we now expect CY26 storage market revenue

212-653-9014 growth of +22.5%, a step-up from our prior forecast of +7.6%. Notably,

CY26 forecast now embeds total market unit growth of only +0.2%

versus ASP growth of +22.3%. By segment, we expect all-flash revenue

growth of +28.7% y/y, HDD revenue growth of +9.6% y/y, and hybrid-

flash revenue growth of +18.5% y/y. Within that, all-flash remains the
