No. Form 144 is a notice of proposed sale by affiliates; it lists planned dispositions and dates such as 04/17/2026 and 05/18/2026. Execution and proceeds require subsequent trade reports or broker confirmations not included here.

Are aggregate proceeds or price information included in this ANET excerpt?

Where can I find confirmation that these proposed sales executed?

Execution is confirmed via subsequent public filings (e.g., broker reports or Form 4 disclosures). The excerpt contains only proposed sale notices with dates; later transaction filings would show actual sales and resulting holdings.
